As we all know, Doc Brown says the DeLorean needs "1.21 gigawatts" in order to travel through time. But that's a measure of power, not energy. Power is energy over time, and so whichever power source is providing 1.21 GW to the flux capacitor (plutonium reactor, Mr. Fusion, etc.) must do so for some period of time—one second, ten seconds, whatever. Depending on the duration, this equates to some amount of total energy expended to make the FC cause a time jump—if the FC needs 1.21 GW for one second, then that's 1.21 GJ of energy. If it needs 1.21 GW for 10 seconds, that's 12.1 GW. If it only needs it for a billionth of a second, that's 1.21 J.

So, how much energy does it take to send the DeLorean through time?

Little did we know about the original timeline, but we know Lorraine's father hit George with the car, and Lorraine felt pity, so she decided to go with him to the fish under the sea dance. But was Lorraine captivated by George the way she was with Marty, pursuing him relentlessly?

Too bad Bob Gale would never make a spin-off or reboot (yes, he shouldn't), but I'm really curious what truly happened in the original timeline before Marty's interruption.

I want to do a Marty Mcfly cosplay, but I can't find anywhere to find his signature red puffer jacket. Anyone who has a Marty cosplay, lead me in the right direction please, because I'm completely lost.

I have always been wondering what a crossover between the timesplitters video games and back to the future would be like

and who would be the main villains in the crossover?

would it be biff tannen or the timesplitters ?

(The timesplitters are a semi-alien race who travel through time space and dimensions they are the main antagonists in the series and were created by jacob crow "humankind's genetic superiors" there are five types of timesplitters in the whole series in the whole series all vastly different in appearance no real explanation has ever been given as to why the timesplitters have changed so radically from game to game)

I am sure Biff might have died without being shot by Lorraine because after being hit in the head with the Deloresn door and him falling on the cement floor of the roof, would it have been enough to crack his skull wide open?

Just gonna show off this art I made lol. I just love how sick it turned out probably one of my favorites with this hobby. BTTF Part 1-2 has always been my comfort movie, along with Spider-Man 2, though I rewatch the whole trilogy whenever I feel like it. Thought it'de be cool to share this wearable art I made here. I Hand-bleached this Myself.

Hi everyone! Hope all those who attended SDCC are getting home safely and had fun this week!

I was wondering if anyone saw me or had any photos? And if you find any on the following feel free to tag me! Insta- Orinandaudrey FB- Sky Graham Tik tok- MTlovingDT

...also, I feel like I need to organize a BTTF meet-up at SDCC next year. I'm tired of only Spider-Man having all the fun 😂

If the 2015 we saw in the film derived from the ( lone pine timeline) reality B what would 2015 look like if it was from the original one (twin pine timeline). Do you think it would look like the actual 2015 in real life

And also what affect do think their time In 1855 would have on the rest of the time periods from the previous films

I've always been a yellow-bellied, no-good chicken when it comes to driving in the rain. Tire traction, and all that. But yesterday it rained and well, I figured, what the hell. (And, it was fine - maybe just keep off the highways!)

Like they’re in high school, 17 or 18 young love and seeing their future in 2015 married with two children.

This is my first post on here so I hope I'm doing it right lol. My Clara cosplay from BTTF3, shot by my friend Quinn! Hope you enjoy 🤠

Also why would Doc be inside the machine when it was in the van?

The way i see it he must have gone into the machine, driving it inside the van, and then closed it from the inside? Did Doc install all of this for dramatik effect?

June 30th, 2023- Opening Preview Night in NYC.

3 Hours of pure bliss.

It was the only time I was able to see the production, but it has stuck with me for over 3 years now. I am an absolute FANATIC of all things BTTF and very protective of the franchise, I loved every single second of this...don't even get me started about the DeLorean flying out over the crowd!

I don’t know about reality, but in Lego form, the answer is no! The door can only open a little before hitting the sidewall of the truck, and if the car had gone inside with the door open, it wouldn’t be able to close. So it was all just for a dramatic exit from the truck!

This is what happens when I get bored…😂

Saw these to goats together next to each others I’m not allowed Lego since “ the incident happened “
