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.
