back to the future - Why didn't doc and Marty just add a small metal plate or something to the old Delorean?


In the third Back to the future movie, Marty digs up a 70-year-old Delorean in a mine, and uses it to go back to 1885. Then, upon arrival, he gets his fuel tank pierced and it leaks all the fuel, trapping him in that time period.


Other questions have mentioned that they might have been able to siphon the fuel from the other Delorean waiting in the mine, but many reasons seem to prevent this course of actions.


But what about preventing the leak itself? They can see the hole the Arrow left, therefore know the exact location the Arrow would hit the car. They would only need to add a very small piece of metal on that exact spot to prevent the Arrow puncturing the car, and neither marty nor 1955-doc knows the new-model delorean enough to risk messing with it by removing that extra piece. They probably wouldn't even notice it. There is no paradox, as the 1955 team wouldn't do anything differently, the metal can be small enough to have no effect on anything (weight, aerodynamism, etc), so everything should play out the same, except for their own delorean to suddenly be full again.


BTTF already established its time travel rules with the possiblity to change in real time objects and events (Marty losing his hand in the first movie), therefore it would not be surprising to see fuel suddenly appearing in their own car.


Other options would also exist, like modifying the car to have a hidden backup fuel tank that automatically fills up with the main one, but isn't used, thus making them "find" this backup tank on their own car right away.


I'm mostly wondering if, and why, doc didn't mention any timey-wimey options, and went straight to the unlikely method of moving that fast with 100 years old tech.


He even invented long-burning chemical logs for the train, he should have at least tried something easier first in my opinion?



Answer



Why they didn't



Doc was at that point still very much against disturbing the timelines. He was stuck in 1885, but instead of asking Marty to come fetch him, he urged him to return to 1985 and destroy the time machine.
He was also adamant he would not fall in love in 1885.


He has hidden the DeLorean, which has worked, since Marty is now in 1885. Going back to the hidden DeLorean to add a piece of metal plating is exactly the sort of thing that could disturb a great deal, causing Marty to disappear from the timeline that landed him in 1885.


Whether it would have worked


It may not have worked. Remember that they didn't have that much time before Doc's date of death. As we've seen, the timeline does not change instantly. In the first film, it took a while for the McFly-children in the photograph to fade. Had they added a reinforcement to the DeLorean, the ripples in the timeline may not have been fast enough to reach them in time to prevent Doc's death.

futurama - How much time is lost in 'Time Keeps on Slippin''

In time Keeps on Slippin' , Farnsworth creates a basketball team which he matures by abusing Chronitons. This leads to time skipping forward by random, but ever increasing amounts. How much time was skipped in this way? Answer Unfortunately, I don't think a good estimate can be made for this, for two reasons: Many of the time skips move forward by an indeterminate amount of time. At one point, the Professor mentions localized regions of space skipping forward much more than others. We then see two young boys on the street below complaining about having to pay social security, only to suddenly become senior citizens and start complaining about wanting their money. Thus, each individual could have experienced a different amount of time skippage.

What is Tolkien trying to say in this letter?

In a draft of a letter, later recorded as #246, Tolkien makes a strange statement. I am interested in the first few sentences of the letter, but I will include the remainder for the sake of context. In the 'Mirror of Galadriel', 1381, it appears that Galadriel conceived of herself as capable of wielding the Ring and supplanting the Dark Lord. If so, so also were the other guardians of the Three, especially Elrond . But this is another matter. It was part of the essential deceit of the Ring to fill minds with imaginations of supreme power . But this the Great had well considered and had rejected, as is seen in Elrond's words at the Council. Galadriel's rejection of the temptation was founded upon previous thought and resolve. In any case Elrond or Galadriel would have proceeded in the policy now adopted by Sauron: they would have built up an empire with great and absolutely subservient generals and armies and engines of war, until they could challenge Sauron and destroy ...

tolkiens legendarium - Was Galadriel's temptation of Boromir instrumental to his fall?

We know Galadriel tempted the members of the Fellowship, did she tempt Boromir with visions of taking the Ring and saving Gondor? In the books, Boromir willingly accepts the judgement of the council that the Ring should be destroyed, but after the meeting with Celeborn and Galadriel his personality seems to change. Was the temptation offered by Galadriel in some way responsible for Boromir's fall? Answer It's likely, but not certain I believe it is likely Galadriel tempted him with the ring, and in doing so re-ignited a pre-existing idea to take the ring, but to be clear lets break this down into three parts. Boromir at the Council of Elrond Boromir after setting off Boromir after being tempted Boromir at the Council of Elrond Boromir pleas for the ring to go to Minas Tirith, to help Gondor in its defense against Mordor. “ Why should we not think that the Great Ring has come into our hands to serve us in the very hour of need? Wielding it the Free Lords of the Free may surely...

harry potter - What is the difference between Diffindo and Sectumsempra?

In the Harry Potter books, Diffindo is called the 'Severing Charm' and it’s most commonly used to cut ropes and the like. However, in the last book Hermione uses it on Ron but misses, creating a 'slash in his jeans' and his knee gets cut, causing him to 'roar in pain'. We've only seen Sectumsempra used once on screen when Harry directly uses it on Malfoy in the sixth book, but there it's mentioned that he is 'waving his wand wildly'. Wouldn't Diffindo, if used in such a fashion also cause a similar effect? Similarly, if it was able to cut Ron, it would also be able to, say, chop off an ear (George's)? In that case, how are these two spells different, except for Sectumsempra seemingly used exclusively to hurt humans? Answer While Diffindo and Sectumsempra both can be countered by other spells, Diffindo is far more easily countered. Reparo, a relatively common spell, can completely reverse its effect when used once. “He pulled the old cop...
