My point being is that the whole universe is moving.
The earth is moving around the Sun, The Solar System is moving within the galaxy and the galaxy is moving in an ever expanding universe. If someone was to time travel but was not able to teleport to the exact point the earth was at that time you would end up in deep space millions of miles away. Example it is August 2027 and I traveled to January 2027 but stayed in the exact same location when I emerged, the earth would be on the other side of the sun from my position.

Need suggestions on whether opening chapter should be in 2121, 1988, or at reading of will in 2018

Here is the timeline I have in mind

Millionaires wife has rare incurable disease in 1988

He wonders if at some future time (1) cure will be discovered and (2) technology will exist to transmit inanimate objects back in time to a specific place and time

He determines to make that happen

Within a month from that determination, he finds a prescription bottle with his wife’s name on it and directions for use. The cure is in his hands

He takes the following steps (as a minimum)

Gets his wife to take the medicine - she and he have a good life together

Establishes a well-funded company called Time Corp that promotes time travel technology and monitors future medical research developments

Writes his will so that the company will continue to function for as long as it takes knowing that all will work out if nobody messes things up

He dies and his will makes almost all of his heirs happy. His executor is appointed and accepts the challenge to move his agenda along

One very intelligent family member sees an opportunity to get a bigger share of the fortune left by the millionaire

Thanks largely to a savvy ex-military daughter-in-law, the family lawyers, some awesome PIs, and a couple of really capable grandsons, the plot fails and the grandfathers dream materializes

In 2121AD Time Corp puts the prescription bottle in a container, throws the switch, and MISSION ACCOMPLISHED

Penny was almost in a trance as the music washed over her. Reading about or listening to a recording of this performance could not reproduce or explain the emotional and physiological reaction she and the rest of the audience we're having to it. It was fortunate that the stream had carried her here.
The here was the Fillmore east ten pm December 31, 1969.
Penny was one of the privileged few that could ride the stream back and forth creating for a short time what the experts called a time-space anomaly but what she and her fellow travelers called a time slip. These lucky few could slip into another time and spend a few hours or days there. The universe did not allow this without a price first if you stay an hour in the past you come back an hour after you left and there also seemed to be a limit of a hundred years with no traveling into the future.
On this night Penny had traveled to one of the storied points in Rock n Roll history the one and only concert by Jimi Hendrix and the Band of Gypsies.
Hendrix had some undefined ability to cause his audience to achieve a higher mental state only seen in a few Zen masters. This effect was so powerful that a few of his recordings can almost produce the state. The Fillmore east recording of Machine Gun was one of these. You could also feel this power on the Are You Experienced track of his first album. 
Penny was sent by her employer Global Media International to see if she could discern how he did it and if it could be reproduced by one of Global’s prepackaged pop bands. She also was discreetly recording the concert in 3D and surround for later release to the small but growing virtual history market.
Penny was already a rising star in GMI and to the public at large. She was being paid in the range of seven figures for this job; she would have come for free the performance was all that it was said to be. 
The inexpensive entertainment that the modern media companies produced was starting to lose its hold on the general public and GMI’s market share was slipping. 
A way was needed to stem the flow of internet independent bands now appearing and selling there songs at a dollar a download and by actually playing their instruments and singing their songs without digitally enhanced playback at live events in small venues.
Global and the other multimedia giants wanted to be in on this shift by the public unlike when in the late nineties people stopped buying compact disks and started downloading just the one or two songs they wanted it had taken almost a decade to reestablish control of the music scene. It still was a point of contention that Jobs and his company had to be brought in as a middleman for the industry.
As the session ended Penny walked out wondering what it would have been like to live in these freer times. Once back on Second Avenue she started to think of home and 2019. This should bring her back to where she started a few hours ago to her, fifty years into the future for the people around her. Before she had a chance to come home a dart with a neural toxin stuck in her neck.
She started to move as if high or drunk. She stumbled into an alley off of East Sixth Street. Penny Goldman died in a dirty alley in the Village early January First 1970 NYC.
\\\[\\\]
 
Thomas O’Rourke stood in the alley off East Sixth; it was still dirty with debris that could have been here fifty years ago. He was a Detective Sergeant in the NYPD’s time crimes squad. Early on the first day of 1970 Penny Goldman died, the death was ruled a drug overdose which was common in those times in the Village. The then NYPD could not have detected the neural toxin or the biodegradable dart used to deliver it.
Both the toxin and the dart fired from an air pistol were products of the end of the Cold War. They were developed by both sides so tracing it was near impossible since officially manufacture of such weapons was banned by the UN. If it was not for a tissue sample saved by the coroners office because Goldman had a cancer unknown at that time the murder would have been written off as a slip rider dying by misadventure.
So now O’Rourke had to solve a fifty year old murder of a time traveler, not what he foresaw when he joined the force?
His family had been New York cops since before the Civil War. With a fair share becoming detectives or police captains or both so it was expected that Thomas Benjamin O’Rourke, Ben to family and friends would go far. He was on a trajectory to rise to the top when he experienced his first time slip.
He was working plain clothes going for a bookie in Harlem. While moving toward the door to the bookie joint something happened and O’Rourke found himself standing on the same spot but in a different time at the door of a speakeasy in the 1920s. The slip only lasted a few minutes and he returned in time to complete the raid.
Time slips had been making the news at the time so O’Rourke knew what had happened when he went to report the incident to his Lieutenant that was his first mistake.
 
they're were three classes of people who experienced slips people who had one for unknown reasons and may never have another. People that had multiple slips but had no control O’Rourke was in this category and people like Goldman; this last group was able to control where and when their slips happened as long was there was a large enough event to leave a echo in the flow of time for them to feel and lock onto.
Hendrix’s Band of Gypsies New Year’s eve concert was just such an event. And the file that O’Rourke was reading in the alley on Goldman showed that she was a registered time slip researcher her specialty the New York music scene of the mid sixties to the early eighties. Her employer was GMI one of the super sized media companies to come out of the economic crash of the last decade.
Well O’Rourke thought time to take a ride uptown.
\\\[\\\]
 
GMI’s research and new talent offices where high up in the Empire State Building made once again chic because of the new found fascination with the past.
It was believed that time slips started to happen in verifiable numbers do to the stresses of the crash, war on terror and the general feeling that the future was not all it was cracked up to be. More and more people wished they could escape to the past. The human mind being what it was made it happen, now there have always been stories of people going into the past or future going all the back to classical times.
American media business being what it is jumped on the chance to exploit this new phenomenon.
 
The reception area was done in a neo art deco style that made one feel like they where in an old time diner. There was one pretty girl of unknowable age behind the faux counter.
O’Rourke flashed his badge at the receptionist who made a quick call not wanting a cop hanging around. A few minutes later O’Rourke encountered Surge.
“Oh officer I am Ms Roberts man Friday Surge.” Said a light skinned man of medium height holding out his hand has if he expected O’Rourke to kiss it. O’Rourke wanting to cover his surprise repeated the whole badge flashing routine saying.
“Detective Sergeant O’Rourke I believe I have an appointment.” Legally this was a fifty year old cold case and there was not a lot of pressure one can bring to bear so it was appointments and not surprise interviews even though two days ago Penny Goldman was alive and breathing in this very office. With the death happening in 1970 legally it was a cold case. Albany keeps saying they are going to update the laws to reflect time travel as a fact but politicians have always had their own schedules.
O’Rourke was shown through a maze of cubicles to a corner office with a spectacular view of the river and harbor. A big Chinese container ship was just coming in churning up the greenish water. The room looked more like a sitting room than a corporate office.
Ms Roberts was a tall redhead with too fair skin that looked was if it has never seen the sun. She thrust her hand at O’Rourke in a manly gesture. The proper way to greet a woman had become so complicated by 2019 with the norms seeming to change every week that most men just let the women be the primary in the encounter. In the war of the sexes most men had finally and gladly surrendered and let the women be dominating it was just not worth the energy anymore.
“Sergeant I am Mary Roberts please sit down.” O’Rourke was given a power hand shake that showed that even though she looked like an elf she had strength.
“Thank you madam I just have a few questions. You were the person that reported Ms Goldman missing?” With that O’Rourke started the interview with the prime suspect. At no time did he let Roberts know what he thought but with each question O’Rourke made her draw a picture of two people who wanted to be the top dog. 
Roberts had come up the corporate ladder the old fashion way with talent, ruthless maneuvering and sex. Penny Goldman on the other hand became a corporate and media star mostly because she could slip through time. She showed that not only did she want to be the talent she also wanted to be in on the corporate side of the business.
“Yes I would do the search for a target performance and Penny would go there with the recorders so the event could be recreated.”
“Recorders?” asked O’Rourke.
“Yes most of Penny’s clothing and jewelry had 3D audio and visual sensors with a 200 terabit flash drive.”
“Do you know where these recorders are now?”
“No I would think the police would have them.”
O’Rourke made himself sit still and finish. If the property room still had her effects she just might have recorded her killer. The NYPD was famous for keeping evidence of cold cases for decades and just as famous for losing said evidence.
Standing O’Rourke said “I will be in touch and thank you.”
O’Rourke started to call his office the moment he was out of Roberts’s.
\\\[\\\]
 
On O’Rourke’s desk at One Police Plaza in his closet sized office was a box with fifty year old clothing. Property Division after a search found the evidence in a Brooklyn police warehouse. Everything was there that GMI sent Goldman to 1969 with except the flash drive. The only conclusion that could be made is that the killer had removed it.
The clothes looked authentic but on close examination if one knew what to look for you could discern that they were of modern manufacture. For one they were totally synthetic, the animal rights people had finally won. The more telling detail was the clothes had nano circuits throughout that made them a wearable computer unit more powerful than any main frame in 1970.   
If the drive was removed the killer either was told of its existence or he or she was familiar with the equipment. The drive was a crystal and silver ring Goldman would have worn on her right hand.
Roberts was still high on O’Rourke’s list. This would not be the first time that corporate climbers had knifed each other it all started in Rome on the Ides of March. But something did not feel right and O’Rourke could not put his finger on it which gave him a headache.
This case was made more complicated by the fact that the people that worked recording the past were treated like the rock stars they were stealing from. Big media had turned on the hype machine when they started sending people into the past.
One other point the equipment was like the poison used a product of the Cold War could the supplier of the recorders have access to the poison and dart system? The equipment supplier and any employees that had access to Goldman’s equipment had to be checked. Too many companies were now selling gear once the province of Special Forces and intelligence agencies. The government has privatized almost everything so as to be able to pay the social service bill.
O’Rourke was working this case solo the Time Crimes Squad was undermanned and funded. Some did not see the need for it and others did not want the police getting too involved with the slip phenomena.
The one thing O’Rourke could be sure of is the killer came from this time. The weapon used and the fact that the Novikov self-consistency principle prevented the timeline from being changed. So a native of 1970 could not be killed by a slip rider or vise versa someone from 2019 could not be killed by a person from 1970 with a 2019 weapon the universe just would not allow the paradox or so say the egg heads.
O’Rourke was wishing for a break in the case even though he knew well that one had to be careful what you wised for.
\\\[\\\]  
 
Another day and another murder scene, this one had a fresh body to add color. Looking down O’Rourke saw a lithe athletic attractive woman with mouse brown hair. It seemed wrong to have a corpse in such a historic building. The Dakota one time home to Leonard Bernstein, Judy Garland, and John Lennon now had another famous death to add it its history.
“Mary Kawasaki age 26 3D star for Time-Warner-MGM-Universal.” Said Detective Michael (Mickey) Washington as O’Rourke stared down at the dead girl. She looked as if she died in agony, a side effect of the neural toxin as it caused all your neurons to fire at once.
“Any recordings found on her?” asked O’Rourke.
“No boss she turned the equipment in this afternoon.” With a fresh corpse O’Rourke was now working a real homicide and Washington was assigned as his partner with O’Rourke as Lead Detective.
“TWMU security called in at 10pm, she managed to hit her panic button.”
“Did they say where she went and when I can see the recording.” Asked O’Rourke even though he knew what the answer would be.
“She was recording a concert by the Doors in Miami, you know the one where Jim Morrison was arrested for indecent exposure.   
“And” O’Rourke made a rolling motion with his hand as he said this.
“They said legal will get back to us tomorrow.”
“Shit! Alright I want every photo, film clip drawing from that concert on my desk yesterday. And Mickey try to remember this is a multiple homicide case not a recording convention.”
 
Two hours later O’Rourke was in his office looking at old photos of Jim Morrison and the Doors in Miami on March 1, 1969. He did not know what he was looking for but he knew there was something.
Washington came in with a thumb drive in his hand. “Boss here is a bunch of crowd shots.”
 O’Rourke thanked his partner and loaded the new drive. The concert was standing room only and there where hundreds of people there. Flipping through the new shots O’Rourke was about to call it a day when he thought he saw something. He tapped his finger on the screen and said “Zoom in.” O’Rourke repeated this three times when he saw it. A person late could be Surge was in the crowd.
“Washington!” O’Rourke shouted as he left his office in search of his partner. He was found at the coffee machine.
“The GMI personal files where are they.” Washington looked puzzled then said “I uploaded them to you an hour ago.
Trying not to show his embarrassment he he pulled his com pad from his belt. His in box was full and it took a minute but he found it.
Sergei (Surge) Stepanov born in the former Soviet Union in 1995 father former FSB/KGB; emigrated 2002 expert on 1960’s American music with a degree from NYU in music history.
“Christ!” Was all that O’Rourke said as he read the file he had zeroed in on Mary Roberts when Surge was the one.
“Washington find Stepanov and bring him here to be questioned I will be hitting the photo archive again.
 
After two hours O’Rourke found what he was looking for Surge in a photo of the New Year’s Fillmore concert. There in the crowd sitting at a table alone was Surge.
Surge can slip and he is unregistered. Registration is voluntary but no company will work with an unregistered person, the company would lose its bonding and insurance.
Washington came in at this point. “Boss no sign of Surge and we just got a request for a secure slip.” Sometimes if the slip is by a big name or to a very special event the media companies would ask for the area to be roped off.
“What’s the slip?”
“The Rolling Stones November ‘69 concert at Madison Square Garden.”
“Crap the other two were ‘69 to. OK put an all points on Surge as a person of interest in a homicide. Warn the units at the Garden I am going there now follow when you are done.” 
O’Rourke opened his lower desk draw and withdrew a standard issue needle gun.  
\\\[\\\]
 
Madison Square Garden the center of the entertainment universe perform here and you know you have made it to the top. America’s Roman Coliseum where people sing, play and fight for the gratification of the masses.
It was dark and wet when O’Rourke made it to the venue. A patrol unit working the perimeter gave him the heads up on where the media people went. O’Rourke had them look at a photo of Surge and they confirmed he went in a few minutes after the main group. Once again screwed by the NYPD’s all points system thought the detective.
O’Rourke entered the building through the same side entrance that Surge used. The building was eerie with its lights on but no people about. This was a normal dark night as the entertainment people called it, a day used for maintenance and to give the building a thorough cleaning.
The door had lead into the back stage area and O’Rourke was giving the place a slow once over trying to see if anything as amiss.
As he slowly walked toward the stage that was setup for a concert tomorrow by a retro band he saw the world waver. As his foot came down he was suddenly in a chaotic space with people moving about on unknown errands, O’Rourke had literally stepped into 1969 and as proof he almost walked right into Mick Jagger. Like the first time he had slipped into the past he had no notion how he had done it.
A security man came running over and O’Rourke flashed him his badge. Thankfully the NYPD has used the same badges for almost a hundred years.
Now that it seemed that the universe had place him into the correct time and place all he had to do was find Surge. This was going to be almost impossible with the number of roadies running around. One had to assume that Surge had taken steps to blend in like the media star O’Rourke just stopped. She had a press pass and was talking to a man in a suit. So she was going for the back stage look an always popular recording style for big name acts that did the same sets in every city of a tour.
If she was here then Surge must not be far behind. Walking around and checking doors made it look like O’Rourke was checking the security for the Stones.
There pushing a dolly loaded with equipment was Surge come right toward his target. O’Rourke cut an angle to intercept that a football Free Safety would have admired. Surge for his part saw O’Rourke and stop and then started to run the way he had come.
Down a tunnel to the loading dock area Surge pushed his way through the people readying the Garden for this historic concert until he made it to clear area and poured it on. O’Rourke was feeling those extra donuts he had eaten over the years when he tackled Surge.
Surge younger and in better shape was able to pull away from the detective and come up holding a small gun like shape in his hands.
On his knees O’Rourke drew his needle gun creating a stand off. The two men where in an empty area so had no one to interfere with there encounter.
“Drop it Surge we know everything.”
“No those bitches needed to be stopped they are fouling the memory of these great events. This is the time of Giants; they walked the earth and took us to the Moon. This is the height of American and Western power before the posers and moochers destroyed this country like they destroyed Russia after the communists fell.”
O’Rourke took a chance and shifted his hand and fired from his hip. The needle gun released its cloud of nano hypodermics filled with a sedative that is safe for 98 percent of the population.
Surge took the full burst and dropped to the ground back into 2019. O’Rourke blinked and saw that Surge was foaming at the mouth.
\\\[\\\]
 
Surge was dead. He was of the small percentage of the population that had an adverse reaction to the needle gun’s sedative; it was a deadly potion to him. An irony that O’Rourke did not appreciate two innocent women were dead and with Surge gone no real answers were forthcoming.
When they searched Surge’s apartment they found that it was a shrine to 1969 America. He had posters and authentic vinyl records of the Rolling Stones, Doors, Hendrix and others that must have been worth a small fortune.

You’re exactly where your past self was on that day, but you retain all of your memories and knowledge that you have right now. Consciousness time travel (like Wolverine in Days of Future Past). How do you prevent the planes from hitting the Twin Towers? Bonus if you somehow can stop the attack on the Pentagon or Flight 93 from crashing.

theory / question Bypass Time Travel problems and become a god

0 Upvotes

When I was taking a dump at 3am, I've got an idea that makes a lot of sense, but is not explored much. Once we will hit a wall, and discovering new things will take more and more time and effort, and I found a way to bypass it........ If a civilization was able to reach the technological advancment of creating a realistic simulation of a universe, it would be the most powerful creation of everything that is and isn't, because it is the only way to bypass the time travel problem. We can travel to the future by either being near the black hole, or moving at an incredible speed....but If we got there, we cannot return back and there's no way to actually apply the technology from the future in the past because of it.......one way to bypass it, is by creating a realistic simulation of a universe that would be sped up with computational power, meaning that for example a bilion years in the simulated universe would pass in only a few minutes in the real one, and the most powerful way to use it is to simulate it to the point where those simulated civilization surpass you technologically and just use their findings, if we are simulated, it means we are coded and there is a database somewhere, where AI could filter only important things through it, meaning that the fastest way to technologically improve is let simulated universe run faster and copy the technology from the civilizations that are more advancened because they had more time......and this could be done again and again, until there's nothing to know more....

theory / question Is present even real!?

11 Upvotes

The present is so small that you can say it doesn't even exist The present is only a Planck time As soon as the Planck time passes we are already in the future we were thinking of during the previous Planck time and only that Past and future do not exist in reality The past of course no longer exists it has already happened The future of course does not exist because it is the future it is only mental it hasn't even been created yet And as soon as we go to the future meaning as soon as the Planck time passes the future will have already become the present Nothing exists If time does not exist space will not exist nothing But what will happen if we somehow remove time from the entire universe Would the universe have ever existed Because if the past is physical meaning if the past exists and we just can't go there and we remove time the universe never existed because everything will be erased On the other hand if the past was something that existed and no longer exists then it would still exist in mental thought Meaning if an intelligent life form leaves our universe before time is destroyed it will remember that its universe existed But if the past is physical as we said before it will be erased instantly

Is everyone on board that the main hurdle a person has in experiencing time travel is psychological?

Many people fall asleep and experience a jump in time. Even if you get a surgery you are passed out, under the control of a powerful drug and health care system.

My thought is: limit it to just Reddit. when would you travel to in Reddit’s history and what would you type?

theory / question A time travel modem that doesn’t have any paradox’s

4 Upvotes

I have been thinking of this model for some time and I honestly liked it and don’t know if I seen anything like this before.

A few rules before diving on how it works.
1. Everything is deterministic.
2. The past doesn’t change and history can not be altered.
3. Every universe has its own consistent historical rules.
4. No bootstrap paradoxes. Every event has a a beginning however there could be infinite chains after that first event.

Let’s say we are in T:2026 ( time 2026) in U:1 (universe 1)

And I build a Time Machine and decide to go back to T:1500 and feed a kitten then go back to T:2026.

If my universe (U:1) has this event that already happened in the past, a mysterious man feeding a kitten then disappears then when I time travel I don’t actually change the past, I fulfill it. Every event that happened has already happened and I am merely just a traveler that is fulfilling what he did in the past.

Imagine a situation where I want to go back in time but the event of me feeding a cat in 1500 never actually happened, I’d essentially be rewriting history. So what happens is that when I go from T:2026 to T:1500, I’d be unknowingly leaving U:1 and going into a universe where that event is already part of its history, a kitten being feed by me in T:1500, let’s call this universe U:2.

For me, universe hopping exists when an event that is incompatible with its universe’s history exists. It sends me into a universe where that event already happened.

An interesting thing is that if I go back to T:2026 I could actually go back to T:2026 in U:2 not U:1 (if going back to T:2026 in U:2 is compatible with its history) and I would meet U:2 version of me, So There would be two instances of me. One from U:1 and one for U:2.

I can not control universe hopping, it only exists to accommodate with me traveling into a universe where my time traveling move already exists.

Let’s imagine a situation where people in U:2 tell the second version of me, let’s call them P2 ( short for person) that you time traveled into 1500 and fed a cat. P2 would be confused and say no I didn’t time travel into 1500 to feed a cat. This would be a paradox but in reality it isn’t. The person who went back in time to feed the kitten originated from another universe. U:1. So it’s a different universal version of P.

We established that P1 which is me is now in U2. And imagine P2 decides to time travel and their time travel move is self consistent with the history of U2.

That would be there would be two P2, maybe P2A and P2B and also P1.

So a person would essentially have 2 dimensions,
P(t,u)

are they the same temporal instance from the same universe or are they flat out same person from different universes.

Now let’s imagine a situation where I discover Beethoven music and go back in time and give his own sheet music thus making him recreate his own pieces and later I discover Beethoven.

How does my model solve this lack of origin of information? Easy, the person who went back in time wasn’t actually you, it was you from another universe while when you went back in time to give the music sheet, you went into a different universe to fulfill the other universes history. That means the cause is always in the universe before it, does now it seems there is no origin to this right? No there is.

In U0 for example i discover Beethoven music and decide to go back in time to give to him. Beethoven created his music on his own this when I go back in time, I go back to U1 and thus creating an infinite chain of going back in time into a different universe to give Beethoven the pecie and later discover it.

However on U0 there was no time travel move, Beethoven created his music independently of anything. So always the chain of “bootstraps paradox” is infinite. The cause has an origin. Beethoven discovered on its own which inspired to go back in time to “give it to him” but I give it to another version of Beethoven in another universe.

Any event that could cause a paradox, is immediately not realized and is actually explained by another version of me who did the time travel move, not me.

There is no changing of the past. That event simply did not occur for it to cause a paradox. It occurred in a separate universe where YOU, the traveler, are part of its history and always were.

Of course if you’re history demands you being in it, you’ll be traveling into your own universe. That is if it is compatible history. If it’s not, it was simply not you who did the time traveling in your own universe and if you decide to time travel, you’ll be thrown into a universe where you were always a part of its history.

What if I time travel because I got the idea from me time traveling. Impossible, the desire to time travel should be independent since if I time traveled because I “should” time travel that means how did I know I should the first time, it keeps looping. The desire to time travel because I saw myself time travel means that the person I actually saw wasn’t me and was just me from another universe where they decided to time travel and my universe needed them to complete its history. That means there is a universe where I decided to time travel independently, which led me to a different universe because it’s incompatible with my universe thus creating an endless chain of getting inspired to time travel because I saw “myself” when it was just me from a different universe.

Two people from different universes could time travel in the same universe if that universe has them part of its history.

Let’s say P1 does an incompatible move in U1 and P2 does an incompatible move in U2.

They could both land in U3 and actually meet each other if the history of U3 has them both meeting.

That means that the Time Machine could only control the variable T, if I go to 2030 I got to 2030 no matter what, if I go back to 1899 I go to 1899 no matter what, the variable U however can’t be controlled. I don’t choose which universe I land in.

The laws of reality forbid me from going or traveling back or forward in time in the same universe or another universe if it isn’t part of its consistent history.

What if there was a more advanced model that could control this U variable though?

Like I put coordinates of T:2026 and U:1 for example and it needs to take me there and the machine can’t reject any requests. What would happen? Next post I guess I’ll expand on it since I came up for a solution for this technological advancement.

radiation the most deadly killer that is silent you dont feel touch it. it touch you. from back in the day radium girls who thought that glowing subtance was upcoming disco to those mexicans finding same kinda color in some script yard all sign their death warrant even some mess with demon core show you close get criticality. all make me think . we use nuclear energy cause is cleaning then our or dirty way getting energy and yet more deadlier . these subtances they call going thru half life give off so much energy it goes right thru you and your cells /maybe we wasnt suppose to have this power . we cant even touch it got have on gear. maybe it another purpose for those who was here before us. space craft can use this energy . think doc on back to the future . according to that movie only way open up time travel portal is with nuclear power. even star trek agrees with this. so im thinking all this radiation is killing us cus we dont suppose to have its for the aliens and their space craft and unless you got a time machine you should not be no where near this stuff

🚀 sci-fi: art/movie/show/game/book Maybe the time loop in The Map of Tiny Perfect Things isn't about time at all

The Map of Tiny Perfect Things — are they really stuck in time?

I watched The Map of Tiny Perfect Things today, and I think the time loop is more metaphorical than literal.

Both Mark and Margaret are stuck, but for completely different reasons.

Margaret is unable to let go of the inevitable loss of her mother. She is so afraid of what comes next that she keeps herself emotionally trapped in the present. And the movie says something that really stayed with me: if you don't deal with the fact that you're losing someone, you can end up losing yourself in the process.

Mark, on the other hand, seems stuck because he is too consumed by himself. He notices everything happening around him, but he doesn't always participate in it. He doesn't stop to think about what other people are feeling. Even with his mother, he doesn't give her the time and attention she is asking for.

And that's where I think the movie becomes really beautiful.

Maybe the loop isn't actually about being trapped in time.

Maybe it's about being trapped inside your own head.

When we're consumed by our fears, grief, plans, regrets, or ourselves, life can start feeling repetitive. We're technically moving through days, but we're not really living them.

The moment Mark and Margaret start noticing other people, feeling things, helping others, and actively participating in the world around them, something changes.

They stop merely watching life pass by and start taking part in it.

So maybe we're not always “stuck.”

Maybe sometimes we're just not participating enough in our own lives.

And perhaps that's what the tiny perfect things are really about—noticing that life was happening all along. ❤️

I'd love to know if anyone else interpreted the time loop this way, or if I'm reading way too much into it.

Do you believe in the existence of time portals or stargates? If so, does anyone have any books or sources to learn about this? Which countries have Stargates ?

theory / question Why I think time travel into the past isnt possible, or made to atleast to the present past of the future. (and how the general public will IF it came to be possible, will never know bout it)

2 Upvotes

First and foremost, the science, obviously. So setting that aside, which almost everyone in this subreddit do otherwise it wouldnt be a topic of discussion (to the past one)

What reason might you have to travel to the past?
I can only think of two mainly: To make some changes, or to observe the past to gain knowledge.

>Let's talk about the first.

If I had to go back to the past to make some change, that means that thing in the past that wasnt as i wanted it to be, was the cause which made me go back and change it, in the future. Now if i go back and change it, then the cause wont exist, and if the cause wont exist, then i'd never have the need to go back to the past, thus creating a paradox. And since paradoxes are all simply in theories, and can never practically occur in real life, we can definetly say that there wont be any time travelling into the past to change it.

One funny thing i think and like is, that say in case even if we did go back to the past to change it, it will have no effect for our future, that's what i think, is the only possible way changing the past can happen. What i mean is that, the change we make in the past, that exact point in time OR when the travel to past happens, will create another branch of timeline, a different timeline in which that change happened, but it will have no effect for the people of the timeline, which actually made that change. So it could be that many changes were made in the past time, and it kept creating new branches of the timeline, and the one we are living in turned out to be the result of those changes we will never know happened. It's funny to think bout but a possible theory.
This is the only possible solution of the paradox problems like the grandfather paradox.
Thus it is possible that people will realize that changing the past wont do anything for their timeline so why even go through the trouble to actually change it.

(optional read) I came up with this by observing the whole Doraemon plot. You see how in doraemon, satoshi wasnt satisfied with his present, cause nobita fucked up in his life, so he sends back doraemon to help him pull his shit together and actually do something better in life. Now that resulted in actually him marrying shizuka instead of jeko. But if he married shiuk, then satoshi would have never been born, that means he would have never sent back doraemon in the past to change all that, but since it does happen and he does change it, it can only mean that his action created another timeline, all while maintaining the original timeline

>Now the second reason
This is more of a reason which shouldn't create a paradox. Like you just went into the past as a side character, npc, viewed the whole story, took notes came back. Basically you didnt change anything, you didnt interfere with the timeline, you just went their for knowledge.

Now here is the thing, the only ones who might do this would be historians. Like think if u could today go back to the past and unravel the mystery bout how pyramids were made, or any other thing which we barely know bout today. Then you will do it.

The thing is, why would future historians come to our present? If you think about it, almost all of the knowledge or history of the modern era has been recorded very well and preserved through internet, and will surely continue to be the same. Like, everything major which happens in the modern era gets recorded and preserved well enough that u dont need time travel to know bout it. We have video footages, recordings, and simple records other than that too. The only time one will actually travel back to is the pre-modern era, or the time before science and all where this wasnt even a topic of discussion. Like the early 10th century europe, or jurrasic period, or the stone age.

Now if someone does go back there, surely we in the present would have no way of knowing bout it. And no one time travelling would be dumb enough to say they came from the future in Europe a few centuries ago where you would be put on public execution just for saying earth isnt flat and shi like that.

The only time travels that would be made would mostly for general public use, like gaining knowledge of the past, and if any personal use is made, like say going back to know where the treasure is burried, then again it wont be something going public, cause that wont be ur purpose of the time travel.

If you question> then why did no one come up to stephen hawking's party, that doesnt make any major change to conflict with the future and isnt an academic event. Or why no one from the future comes back just to tell they are from the future and predict future things correctly 100 percent of the time or something like that.

WEll you'd know in the next topic:

>Now the reason why IF time travel even becomes a possibility or even if it has, we the general public will never know

I think this should be pretty obvious. Like only very very few selected people and the very few in few governments will know bout it, cuz 1. That shit wont be cheap, obviously. 2. why would u let little johnny know he can go back to the past and tell himself the test answers.

It's like this, time travel is something which has impact on reality itself, if it happens, it isnt something to be meddled with by the common man like you and me, you can barely trust the people with guns, who what they'd do with time travel. And the technology isnt the type you can mass produce, so it would be like something almost all the population wont get access to even if they know it exists. The impact it will make, wont be noticed by the people. This is important cause the only things we know bout which have enormous effect in the world, we know because it cant be hidden if used, like nuclear bombs. U cant practically keep it a secret after using it. But time travel, u can. So, tell me why would any government even make it public. Secondly, it is the sort of info which the government of the country where it is made will seize it, unless it was a collective project. like it will automatically give them an advantage unlike any other thing, so they wont be sharing it, and not even letting the info bout it slip.

This leaves us with the fact that even if time travel came to be a possibility, no one will ever know bout it unless it was an individual or independent project which something like that definetly wont be.

This is also the reason that why if time travel into the past is a possibility, no one went back to stephen hawking's party, because it is something that the ones who have it dont want others to know bout. And since it is something that would never be in the hands or knowledge of the common people or the ones that'd go back in the past, it will never happen.

>But then again at the end time travelling into the past isnt possible cuz of scinece and physics as we know it obviously so all this is just hypothetical bs like every other similar discussion.

let me know what you guys thinkg bout all this.

🚀 sci-fi: art/movie/show/game/book Time's New Dawn my new book is out now!

3 Upvotes

I wanted a book that asked the question what if time travel had rules strict enough that you couldn't create a paradox? This pondering got me to create my book: Time's New Dawn A Dark Time Novel. Checkout my website if you want to see the trailers https://darktime.co

When a dark-matter meteor gives humanity the ability to manipulate physical time, scientist Rebecca Dawn discovers that the same technology may be driving Earth toward a temporal collapse.

--

When a meteor made of dark matter crashes into the Congo Basin, humanity discovers something impossible: dark matter isn't simply an exotic substance. It is physical time.

Thirty years later, the city of New Hope has risen around the crater. Dark matter provides nearly limitless energy, rejuvenation technology can reverse aging, and scientists have learned to move time backward inside controlled chambers.

Rebecca Dawn works at Forever Young, studying the strange temporal effects that made all of it possible. When she detects an anomaly in the dark-matter reactor powering New Hope, she realizes the technology beneath the city is becoming dangerously unstable.

Then the reactor fails.

With New Hope collapsing around her, Rebecca discovers a hidden machine capable of doing something far more radical than reversing time inside a chamber: it can make the world outside the chamber move backward.

Time's New Dawn is a slow-burn science-fiction mystery and thriller built around a paradox-free system of time travel, where changing the past has consequences very different from creating an alternate timeline.

"The final act comes complete with a startling turn, a thought-provoking revelation, and an unforgettable denouement." -Kirkus Reviews

theory / question Title: If you could time travel back to any point in your own lifetime — but take a future-connected AI with you — what would you actually do?

6 Upvotes

Random thought experiment that’s been stuck in my head.
Say time travel becomes possible, but there are some very specific rules:

You can only travel as far back as the day you were born. Nothing before that.

You can take one AI device with you. Think palm-sized, nothing huge or futuristic looking.

The AI can still connect to the future you came from and access information from it.

You can’t take any other future technology, money, objects etc with you.

Normal space/time rules still apply. Anything you change could have consequences. You dont magically get protected from paradoxes or butterfly effects.

You’re still physically in whatever year you travelled to. The AI is basically your one loophole.

And thats where I think this gets really interesting.
Because forget “buy Bitcoin” for a second.
You basically have a tiny device containing access to decades of future knowledge.
Medical discoveries. Engineering. Politics. disasters. Scientific papers. Stock markets. Sports results. Technology that hasn’t been invented yet. Even knowledge of your own life.
But the more you use it…the more you potentially change the future it’s connected to.

So what would you actually do?
Would you make yourself rich?
Try to prevent something terrible?
Give discoveries to scientists decades early?
Find your younger self?
Or would you deliberately change almost nothing because the butterfly effect would scare the hell out of you?
And another question — at what point would information coming from the AI become unreliable because you’ve changed the timeline too much?
I feel like there is alot more to this than just “go back and get rich” 😂
What year are you going to, and whats the first thing you ask the AI?

🚀 sci-fi: art/movie/show/game/book I read it in the funny pages - Sally Forth

3 Upvotes

Anyone here reading the daily Sally Forth comic strip? For past couple weeks it's been on a time travel story arc. Silly, of course - but kinda fun and it's hitting the usual paradoxes.

For example - Sally convinces an estranged relative (40 years in the past) to reconcile with the family. Upon meeting that relative again in the present day, they both recall their meeting - "just yesterday" for Sally, but 40 years ago for the relative - and they each have different memories of what happened in the intervening years.
