Biff and Delorean

posted by zoitberg on - last edited - Viewed by 2.3K users

Hi everyone !

There was always two things in bttf2 the bothered me.
One is Biff and Delorean and second is Doc become some way commended by goverment (newspaper )

When Marty and Doc travel to the future, senior Biff spot the Delorean and instead of saying some trivial "WTF is this?" He KNEW that this was a Time machine, and knew how to set a clock, go 80 miles etc... Ha ! He even told his younger self that in the future Marty or Doc will go after him.

Question remains : How he knew this much about Delorean?! How he knew this "crazy, wild-eyed old man who claims to be a scientist" ?

In the 2rd part Doc shown Marty newspaper with text "Emmett Brown commended". I assume that in later years he told the world about time travels (and create a Institute of Future Technology <-- non canonical). Then we got two options:

1. Doc in second part (future) is still anonymous, he become recognizable after they alter Biff Hell Valley . In the end of third part when Marty asked Doc about the future Doc replied "we already been there" .

In this timeline (in the future) Biff dont know anything about time travels yet. Doc can build as many time machines as he want because in the future he is... First Citizen Brown (Eeevil Ending ;P )

2. Doc in second part (future) before he come back for Marty he learned that he was honored, he become recognizable person. This would explain that Biff knew what is "Delorean" . But in this time version we don't know how long Doc remained in the future ("Oh no ! Marty's son and his family are in trouble ! I must come back.. but before. Let pimp our Delorean with flying ambility and 18" rims .Yeaach") and.. How may things he know about .. THE FUTURE !!! ;)

There always bother me what "the status" (dead, live,famous, anonymous ect.) have Doc in 2015. For 100% Emmett that goes to the future in the end of first part search for future himself. What he learned? ;) Maybe in game it will be explained...

    If it is an alternate 2015 then Doc and Marty should be alternates too!
    Just because we as the movie spectators stayed at 2015 and didn't follow Biff's trip to 1955 doesn't mean that suddenly there are different rules in the time-travel-theory which BTTF 1 has set up.
    I mean Marty altered 1955 in the first movie and all people that "stayed" in 1985 and did not time-travel were of course affected by Marty's intervention. As the whole 1985 setting was.
    But now in BTTF II when Biff does exactly the same Marty and Doc curiously remain the same and only the surroundings changed? Thats weird.
    So if 2015 changed, Doc and Marty should too.

    I think this is the main reason why I like time travel stories so much, because no one knows what the laws of physics for time travel would really be like, and so rules are able to ebb and flow through different stories and fangirls like me are able to think of their own theories on how a story could believably work. :D

    To me, I've always thought of as a ripple effect in two parts. Biff comes back to 2015 and he doesn't disappear right away because of the time ripple effect as mentioned on the Back to the Future DVD. The future immediately changes around Doc, Marty and Jennifer, but they don't notice it since they're outside the former McFly residence at that point. The way I see it, the reason Doc, Marty, and Jennifer don't change even though their surroundings do is because time reacts differently to someone who has traveled outside their own timeline. The ripple effect takes longer to effect Marty, Doc, and Jennifer because they're displaced from their original timeline.

    I know that was just a typo and you meant biff comes back to 2015 :D

    and yes it could be that it wouldnt make sense for doc and marty to be in 2015 and still remember the alternate timeline since they likely dont time travel in the alternate timeline. Or simply they got out before the ripple effect took place. This is the only instance in the trilogy which takes place immediately after the timeline changes; in part I marty leaves about a half hour after the last ripple (getting lorraine and george back together and george punching out biff) and doesnt get to see the effects til morning. When they go back to 1955 the second time, it's a while before they go back to the present and the only change in 1885 is eastwood ravine. In part II we do see the matchbook, marty's newspaper, and doc newspapers all change at different times despite one event (burning the almanac) causing all the effects; they do all change seconds from each other but still not at the same time meaning the ripple effect is not instant.

  • @Spengler56 said: I'm not really buying this. I think it was originally meant to be a gas alternative and it's function was changed in part 3. When Doc says he needs fuel I think it was meant as a replacement for gas but whatever.

    The thing is that Doc explains it in the first movie.

    Marty:Uh, does it like run on regular unleaded gasoline?
    Doc: Unfortunately no, it requires something with a little more kick. Plutonium!
    Marty: Uh, Plutonium. Wait a minute, are telling me that this sucker is nuclear?!
    Doc: Hey, hey! Keep rolling, keep rolling. No no no no no no. This sucker's electrical, but I need a nuclear reaction to generate the 1.21 Jigawatts of electricity I need.

    Now, if the entire car and time machine ran only on plutonium, then the car wouldn't have been able to drive when it was in 1955 and heading towards the lightning strike without its plutonium.

    The Mr. Fusion was just replacing the nuclear reactor for the electrical part for time travel, and likely also the flight capabilities.

    So when Doc told Marty that he needed fuel, he meant only for the Mr. Fusion reactor, and not that the car completely ran on the Mr. Fusion.

    I'm not an engineer, but if Mr. Fushion supposedly has enough juice to power the 1.21 gw, then whouldn't it be more than enough power for the car to run on? Why not have the car entirely run on Mr. Fushion?

    BTW, is Mr. Fushion mainly a car part? Because it doesn't show on the other cars in the future, if I remember right.

  • @Spengler56 said: I thought this too, but why would he be dead? Was he killed at some point during the second movie? I haven't seen it in a long time.

    BTW, if Biff were dead earlier than 2015, that would also create a time paradox since the events that got Biff the Alamanac would not have happened.

    Biff should not have returned the car. Hell, he should have stayed in an earlier era and make all those bets himself. lol

    Mr. Fusion was always meant to be a replacement for the plutonium, not the gasoline, since the word fusion in Mr. Fusion refers to nuclear fusion, the process by which two atoms fuse, which is how the Delorean gets enough power to travel through time.

    As mentioned in Back to the Future Part III, the DeLorean uses an internal combustion engine. An internal combustion engine combines fuel with air to create force. Electricity wouldn't work at all, and Doc doesn't have the time to create an alternative.

    @Spengler56 said: BTW, is Mr. Fushion mainly a car part? Because it doesn't show on the other cars in the future, if I remember right.


    If it isn't an invention created by Doc himself, Mr. Fusion most likely isn't a car part, since nuclear fusion wouldn't be required for anything a car would need to operate.

    @Spengler56 said: I know that was just a typo and you meant biff comes back to 2015 :D


    Yes, I definitely meant 2015 not 1985. :)

    Plus Marty is the last of his siblings to disappear in the photograph in the first movie, which could be explained either by simply the fact that he was the last to be born so the ripple would reach him last, or that since he's traveled through time the timeline change is catching up to him slower than it did the rest of his siblings.

    I think your first guess makes the most sense. Dave is older than Linda which is probably why Dave starts fading before Linda does. But your second guess holds water as well as marty fades in a different manner; Dave and Linda have different body parts fade out in sequence whereas marty's entire body fades.

    I'm not sure what the thought process for putting Mr. Fusion at the end of part 1 was (remember no sequels planned at this point). Probably so that doc wouldnt have to put on a radiation suit to put the plutonium in just for what they thought would be a gag. Or possibly due to the humour of seeing him go through the trash. But part 2 and 3 were conceived at the same time. So I'm sure they had already considered a problem to have them stuck in 1885. Actually one of the first drafts of the second film was to have Mr. Fusion damaged in the hoverboard chase and have Marty and doc stuck in 2015 similar to part I with the plot to drive the delorean into the grand canyon to get back to the present.

    But anyhow it's clearly shown in the first film that the plutonium needs to be put in for each time travel. Mr. Fusion makes this easier and may possibly allow for multiple time travel without needing to be filled. I'm sure zemeckis and gale realized that if plutonium was not accessible in 1955 the first time around, it certainly would not be a second time around and definitely not in 1885.

    I would think if he can get trash to generate that much power he could it to run the car. He was able to get it to fly. And besides, he had all the time he needed, he had a time machine. :)

  • There's a few problems with that. First, an internal combustion engine and an electric motor work in completely different ways. You can't convert an internal combustion engine to be powered by electricity, he would've had to build an electric motor from scratch. Second, a nuclear reaction produces an enormous amount of energy. Given that there doesn't seem to be any extra energy released (considering that the DeLorean leaves fire trails behind, not an atomic blast) and that it absorbed a bolt of lightning with no ill effects, it can be assumed that 1. time travel requires the full energy of the nuclear reaction, and 2. there's nothing like a battery to store any excess energy.

    Besides, have you seen an entirely electric car? Unless they've made some improvements on them, getting one up to 88 mph could be extremely difficult, if even possible.
