Great video, mate! I can't recommend enough the movie, Primer. A low budget time film but it handles the time travel aspect so interestingly. There are loads of reactions/analysis online, but would be great to get your take on it! Cheers!
I'm glad there's an actual scientist video about the subject, wish people were watching this instead of all the clickbait who clearly don't actually understand it
thank you sir ! we need more people like you which tries to explain things in movies in a scientific way. BTW , I think if you watch Loki ( series ) and upcoming Dr strange 2 , you will see the rules of multiverse in a really better way
Imagine having your work on time travel referenced by Tony Stark in End Game, or even knowing the guy who’s work was referenced by Stark in End Game. That is some gangster ass sh*t.
Bill and Ted's excellent adventure has time travel rules similar to Terminator. It's only seen very briefly when they meet themselves just before and just after the adventure, but it seems to be self fulfilling.
Very informative and Great Video Sir. Bt i have a question that, in endgame they showed us that, in end all stones are placed at the right time when they were taken. my question is " In the case of Tesseract, Stark got that in 1950 at military base along with Captain America, bt when in present Cap goes back in that timeline. Were there two Caps at the same time ??" And how the Replacement of stones happened ?
1) How can you travel back to an alternate reality to return the stones without creating a new one? Wouldn't there just be one where you come back and one where you don't? And isn't cap traveling to the past of those timelines when returning those stones. I thought u couldnt change the past. For example the timeline where thanos travels to 2023 main timeline continues without the power stone. Cap returns the power stone to the past before thanos travels in time but thanos still travels in time to fight in 2023. Or does that only pertain to your own timeline where u come from and you can change the past of other realities? 2) Assuming from the previous question that you can change the past of another timeline to be one that has the infinity stones, the minute they leave the alternate realities with the stones, that creates a dark future for that timeline. When cap returns the stones he would just appear the moment the previous avengers left so no extra branches would be created and the alternate timeline would have the infinity stone. But what if cap met nebula because she stayed back after Rhodes left with the power stone. That would create a new reality after cap returns with the time stone but what implications would that have for the time traveling nebula who is now back in 2023 after they won. Would the new timeline nebula who met cap be able to come back to the present in 2023 after the avengers' victory?
Ishmeet Singh Totally agree with your first point. Simon forgot to clear that up. How did Cap knew that when he brought the stones back, he was in the exact universes B or C that they had created before and not in a new universe D or E? That could maybe just work if he went back the exact precise moment of Universe Bs and Cs present which would require excellent timing. But even then, how can Cap even jump from Universe B back to A. Him beeing quite old when coming back to A would also implicate that in the universe he aged in, time just runs much faster.
Great video. I’d be interested to see a review of the physics of radioactivity from the Godzilla King of the Monsters movie. (*Minor spoilers*) Radioactivity seems to do everything in that movie, it heals Godzilla, makes him burn up when he falls from the sky, and somehow promotes plant growth. And there is the physics of large flying beasts, how much power is needed to maneuver a large flying ship, an “oxygen destroyer” bomb (whatever that means), and at one point using a baseball field as a radio tower of sorts. It’s was a silly movie.
Ahhh radioactivity -- so much more fun in superhero/monster movies than in real life eh? From what you say, when I get around to watching Godzilla King of the Monsters I guess I'll need to turn the physics part of my brain off to enjoy it :)
"radioactive" in sci-fi stories is treated like a magic spell, it can cause anything that the storyteller wants, no explanation needed 😂 and i fall for it everytime, it's so cool 👻
So in terminator 1, no matter what changes happens in the past actually led to what happened to the current future? i find this is more weird than having universe branching off to another. Maybe i didn't fully understand how it works.
Gamora was aboard the Sanctuary II when it arrived, along with Thanos and his army. The only issue I have with your interpretation of Cap's time travel is that it breaks with the rules we're given about how the "time machine" works. If he really did as you described he should have returned to the platform, the implication being that he did not "traveled" at all and let time run its course. Am I missing something? :|
Cheers for the reminder on Gamora's storyline. BTW Am I right in remembering that there wasn't an explanation of how Thanos' mega-ship ('Sanctuary II' I gather from your comment) managed to enter the quantum realm? It just somehow managed to do so once Nebula switched things on at the Avengers' end? Anyway on the cap thing -- yes I agree that the Endgame 'time machine' seems to need a portal of some kind to arrive at -- either the big fancy one they built or the original one in the back of the van. Logically if cap were to return, even after spending 50 years in 'universe 2', he ought to come back to the platform that he launched from. I agree that the audience is led to feel that he came the "long way" just by staying put and ageing -- but if as fans we want to close that loophole we need only suppose, e.g., that he can arrive unobserved a little earlier to that portal. No problem in the Deutsch-type picture with him arriving 'back' before he 'left'!
But if the reality goings to have problems if the avengers decided to keep the stones from the past, because it makes part of the journey that takes them to the endgame fight and they have to return them, so why Gamora can stay on the "present"? Sorry for the bad english, i was more focused on my question
Hi! Just to confirm: So in this “universe A” they killed Thanos 2 times, that means that the avengers “win” in the universe A but also in the universe B, because Thanos came from that universe, so in that universe there is no Thanos, did I get this right? Because without that premise, everything will be inconsistent. So the only future they “really win”(tony is not dead) is the B.
When Cap goes back go put the Infinity Stones back, wouldn't he be creating yet another universe there? So, when travelling from Universe 1 to the past, they take a stone creating Universe 2. They then go back to Universe 1 and do their thing. How can Cap then go back to the point in Universe 2 to put the stone back without creating a Universe 3? It seems to me that Universe 1 and 3 are fine, but Universe 2 will be forever screwed without its stone.
You can think of it either way, but I prefer to think that when two universes split, both did previously exist but they were identical to each other until the key event (e.g. traveller arrives, but more normally just when any quantum-level process can go one way or another).
make video about Rick's gadgets in Rick and Morty series plss, there is a lot. If you haven't watch Rick and Morty then you should, especially people who loves about physics
Yep coz Thor takes his hammer from the past, yet his hammer didn't disappear from his past, suggesting he went back in to a parallel past. Only difference being that Stark made it possible for one to snap back to their own timeline like a rubber band after they've travelled to a parallel past. So Thanos in end game is a different Thanos Multiverse in Marvel appears to be like a fiber bundle.
I see one problem here with Cap at the end. Well, not so much a problem, but a strange detail. To sit on that bench in that moment, he would have arrived in time to get out of the time-travel-suit and go to the bench without anyone noticing. There isn't enough time to do that, unless he arrived before his younger self left. Which means that, via alternate universe, he did indeed travel to the past in his own universe a la Terminator.
Hmmm good point -- but I think we can assume he did just that. Suppose we saw the slightly longer scene: The camera frames the time travel platform. There's a flash and a figure appears and walks slowly out of shot, clearly starting to remove his helmet and gear. Now we see hulk and cap come into scene, and things proceed as in the movie. No problem with this from the multiverse angle. But it might have been a bit confusing for viewers. I'd have liked it though!
Hi Benjamin. I have been approached by Geek Lessons to allow them to use my lessons. I noticed that you have also joined their channel. Do you think this has been helpful for you?
Since you’re a professor of quantum technologies, would you say quantum mechanics also makes logical sense? I’ve heard that it goes against the laws of logic.
Finally got the scientific explanation about the time travel in Avengers end game movie. But I have some questions; 1) You are saying that the avengers won only in one universe(universe 1 acoording to you); and in rest of all the parallel universes (lets say 100-1=99) Thanos won! And as all the universes exists parallelly so ultimately thanos won 99% and avengers 1% ? 2) If the avengers have brought infinity stones from another parallel universe then why did they return those stones? Lets say they didn't return those stones, and as the stones are from another universe it will not hamper the universe1 timeline! 3)And according to your theory Thanos is a dumb! As he could go to another universe 5, instead of universe 1, and get those stones and some pym particles and return to universe 1, and become the king! 4) As thanos knew the future from nebula, he could stay in his timeline instead of coming to universe 1; and then in his timeline let the story end according to Avengers Infinity war but during the first snap he kills all the avengers instead of sparing some of them. That would be wise!
Cheers for the comment. (1) Well, I'm saying that all we know for SURE is that the avengers won in universe 1. Although actually in doing so they killed a Thanos from another universe before he 'clicked' there, so they saved that one as a bonus! As for all the other universes, well many-worlds theory would say that in some of them they won, in some they lost. And in some there is no Thanos of course, because they are just too different. All that said, the fact Dr Strange said "1 in 14 million chance" suggests that in many universes the Avengers may lose! (2) Yeah they didn't HAVE to return the stones, failing to do so would only have messed up those universes not "universe 1". But they are nice guys so they did! After all why not? (3) I think that Thanos does not have his own time travel tech, or even universe-jumping tech, or else he would have done lots of other nasty stuff -- unless he knows something about the dangers of time travel that we don't :D (4) I agree with that -- he could have kept quiet, and then once he has won in his universe he could just kill the Avengers to stop the trouble. But I guess he was pissed at the idea that the 'other Thanos' was having his victory reversed.
Let me propose a scenario and see what you think: Bruce goes back to 2012 and borrows the Time Stone from the Ancient One, creating an alternate timeline, 2012A. Then he goes back to 2023, they use the Stone, and they give the Stone to Steve to take back. Steve goes back to 2012 and finds Bruce before Bruce gets to the Ancient One's Sanctum. He says, "Hey, don't worry about taking the Time Stone from this time; just take this one." Steve was supposed to return the Time Stone to the Ancient One, collapsing 2012A, but instead he's changed history again, creating 2012B. But 2012B is a timeline identical to the original 2012 because in 2012B the change is that the Time Stone isn't removed. Now: Are there two Bruces that traveled back to 2023, each with a Time Stone? The Bruce that traveled to 2012 after creating 2012A, and the alternate Bruce that traveled to 2023 after Steve created 2012B? So now there's two Time Stones in 2023, so Steve can go back and give one of them back to the Ancient One, collapsing 2012A, and they can give one to Dr. Strange in 2023. There's also two Hulks, that don't need to be returned anywhere. If that works, Steve can do the same trick on Vormir, which has other implications.
OK typing quick (in a rush... never enough time! :) First: I can only answer you from the multiverse picture, and in that picture alternative timelines don't 'collapse' in the sense of cease to exist: there is branching where universes diverge but there isn't ever a true end to a branch or a perfect reintegration. I admit the scene with the Ancient One can suggest otherwise but I think we can understand her chat with Bruce to be her explaining the difference between a radical catastrophic branch (when infinity stone lost) versus a slight harmless branch that doesn't even look different in most ways (when infinity stone borrowed+returned). So, your proposal: You want Bruce to go and get the stone as per film, but in the final scenes instead of what we might assume, i.e. Cap appearing shortly AFTER Bruce leaves 2012 and meeting Ancient One and saying something like "Here's the stone back, we Avengers keep our promises" instead Cap appears BEFORE Bruce gets to AO and gives him the stone -- OK so then in multiverse theory, the act of going back to that moment branches that universe again -- in one, Bruce gets the stone early, in the other he does not. This leads to two different 2023 branches, one where he returns and says "Oh it was easy Cap gave it to me, I have a good feeling we're gonna win!" and one (the film version) where he returns and says "Had to have a debate with the Ancient One, she's put her trust in us". So we don't get two hulks in one branch. As far as I can see this doesn't create an extra time stone (versus the number of universe branches we have) it's still the case we have to put them back and all 2023 branches end up without one -- unless the Avengers go nasty and hang on to one. I figure the narrative reason for the Ancient One's debate with hulk is that it closes the huge plot hole of "why not keep the gauntlet and get hulk to do loads of stuff with it, including fixing every sad thing that happened in the movie".
@@SimonBenjamin Thanks! I worked out the same thing last night after I posted, when I started drawing the timelines out. It looks to me like it's not possible to use this one weird trick to generate a free set of Infinity Stones (since the new 2023 timeline would still have Thanos destroying the Stones, and there'd still be timelines without Stones), but going to Vormir before the Soul Stone is taken would at least create an alternate 2023 where everyone came back from getting the Stones.
Actually I don't like to think about multiverse...it's messes everything like present is insulted. There shud be only one universe.. and through time machine we can go back in time but not the one in past come to present. We can go back in time and change present or future but it shud all tally up like integration into one story not multiple stories. Terminator 1,2,3,4 works exactly like that... Things that has to happen should happen anyway in one way or another ,if changed there shud be something the present connects with the changed past. Captain America seen explanation is right..he went back in time , and there is no alternate cap in past..he lived with her love, and he knew where avengers finally reach .so he grew old and waited at the bench . Present and past connects.. Past thanos and army came to future- that's future travel...breaking the system actually but overall past and present shud connect . Thanos died in present... His old self came into future and dies. Events resulting to his death changed.. In men in black 3 , also past ,present and future co relates with each other . Just by time machine we witness extra events which shapes the present.. If we go back to past and prevent our birth which means we are wiping entire existence in past, present and future.. if we try to break the system, then it's like windows blue screen in time machine .. or the system should run with the extra events...which ultimately integrates into one... One way or other.. and there is always a limitation... Yes I know so the questions in what iam said is how the rest of things run if there is change in past. Like past thanos dead , past gamora came in to future , so thanos didn't kill Loki and others for infinity stones. But we don't need to think like that's... If thanos is not there, something else should have happened to Loki . But present or future is set... Also when Captain America goes to past and live there, the old cap is still in ice water frozen and dies in there bcos nobody go retrieve the wreckage since the old world has already got Captain America thereby freezes cap shud die in there..and the events of past Captain America didn't happen or happened without his contributions. Or he worked old and retired in present as we seen at the end scene... If we dig up thinking like this.. it messes a lot of things... But better like I said things happened like terminator way... The end
Yeah, like I say in the video Terminator (also HP, Interstella) go for the the idea that you go back into the "one and only" past but everything you do just turns out to be consistent with the future you came from. But Endgame doesn't (and can't) use that idea for what time travel is. You can't 'borrow' infinity stones without making some change that must affect the future. (Well I guess they could have borrowed them all from times when they were just in storage and no one would know they 'blipped out' for a moment... but that would make a boring film!)
@@SimonBenjamin antman says his 5 hours in quantum realm was 5 years in reality. May be the stones just disappeared for seconds in the past .. and returned by cap . Then at present , stones will be there where it's supposed to be irrespective of thanos destroying it .. half of universe came back alive, stones too but ironman used the powers of stones from d past. . Let it be this way. Thanos came from past to present! So he didn't kill Loki and Asgard which means at present they also shud hav come back alive and living somewer. Which we can just guess.. Then from a suitable timeline old ironman and black widow can be picked and brought back to present explaining them all.. this should be the limitation.. or they can do it again instead of mourning. past should change which sets with future. Our terminator theory can be applied 90% by making up things just the movie can't show everything.. and Captain America is d proof of it..
Amazing explanation.!!
Could you also break down the loki series? The last episode messes with my mind everytime I think about it.
You’re analysis of science in movies is really fun could you please do more?
Great video, mate!
I can't recommend enough the movie, Primer. A low budget time film but it handles the time travel aspect so interestingly. There are loads of reactions/analysis online, but would be great to get your take on it!
Cheers!
This is great. Thanks for making it! 12 Monkeys is another Terminator style time travel movie. Can recommend.
@7:20 to skip all the context and get to business

Please could you do a science of Captain America video?
Bill and Ted's excellent adventure has time travel rules similar to Terminator. It's only seen very briefly when they meet themselves just before and just after the adventure, but it seems to be self fulfilling.
What happens to the actual Captain America who already exists in universe 4, if future Captain America comes from universe 1 ?!
Please make more videos
Very informative and Great Video Sir. Bt i have a question that, in endgame they showed us that, in end all stones are placed at the right time when they were taken. my question is " In the case of Tesseract, Stark got that in 1950 at military base along with Captain America, bt when in present Cap goes back in that timeline.

1) How can you travel back to an alternate reality to return the stones without creating a new one? Wouldn't there just be one where you come back and one where you don't? And isn't cap traveling to the past of those timelines when returning those stones. I thought u couldnt change the past. For example the timeline where thanos travels to 2023 main timeline continues without the power stone. Cap returns the power stone to the past before thanos travels in time but thanos still travels in time to fight in 2023. Or does that only pertain to your own timeline where u come from and you can change the past of other realities?
2) Assuming from the previous question that you can change the past of another timeline to be one that has the infinity stones, the minute they leave the alternate realities with the stones, that creates a dark future for that timeline. When cap returns the stones he would just appear the moment the previous avengers left so no extra branches would be created and the alternate timeline would have the infinity stone. But what if cap met nebula because she stayed back after Rhodes left with the power stone. That would create a new reality after cap returns with the time stone but what implications would that have for the time traveling nebula who is now back in 2023 after they won. Would the new timeline nebula who met cap be able to come back to the present in 2023 after the avengers' victory?
Ishmeet Singh Totally agree with your first point. Simon forgot to clear that up. How did Cap knew that when he brought the stones back, he was in the exact universes B or C that they had created before and not in a new universe D or E? That could maybe just work if he went back the exact precise moment of Universe Bs and Cs present which would require excellent timing. But even then, how can Cap even jump from Universe B back to A. Him beeing quite old when coming back to A would also implicate that in the universe he aged in, time just runs much faster.

I recommend you to watch the tv show 12 Monkeys. I think the way in which they explored or developped time travelling is mind blowing :D
Several friends have told me I should watch it. I either love or hate time travel movies... usually hate!... but that sounds like a good one.
Make a video about dark series
I heard "Deutsch Proposition."
So I guess they sort of fictionalized it while giving him credit for the ideas they used? Pretty cool.
Yeah that's it: "proposition"! Thanks. I think that's fine, similar to "conjecture".
Hey, How can I get into OXFORD UNIVERSITY from INDIA in medical science

Wheres our physics analysis of hulk??

@@SimonBenjamin It was implied that Ebony Maw, the old bald grey guy, was able to recreate the Pym particle and apply it to the whole ship
But if the reality goings to have problems if the avengers decided to keep the stones from the past, because it makes part of the journey that takes them to the endgame fight and they have to return them, so why Gamora can stay on the "present"?
Sorry for the bad english, i was more focused on my question
I think you meant to say, "Along with Terminator 2" lol first move is good too but the 2nd is better :D

Yes the team from Universe A sorted out universe B as well, Tony in B doesn't even need to hear Thanos' name :D

When Cap goes back go put the Infinity Stones back, wouldn't he be creating yet another universe there? So, when travelling from Universe 1 to the past, they take a stone creating Universe 2.

Tenet
Let me propose a scenario and see what you think:
Bruce goes back to 2012 and borrows the Time Stone from the Ancient One, creating an alternate timeline, 2012A. Then he goes back to 2023, they use the Stone, and they give the Stone to Steve to take back. Steve goes back to 2012 and finds Bruce before Bruce gets to the Ancient One's Sanctum. He says, "Hey, don't worry about taking the Time Stone from this time; just take this one."
Steve was supposed to return the Time Stone to the Ancient One, collapsing 2012A, but instead he's changed history again, creating 2012B. But 2012B is a timeline identical to the original 2012 because in 2012B the change is that the Time Stone isn't removed.
Now: Are there two Bruces that traveled back to 2023, each with a Time Stone? The Bruce that traveled to 2012 after creating 2012A, and the alternate Bruce that traveled to 2023 after Steve created 2012B? So now there's two Time Stones in 2023, so Steve can go back and give one of them back to the Ancient One, collapsing 2012A, and they can give one to Dr. Strange in 2023. There's also two Hulks, that don't need to be returned anywhere.
If that works, Steve can do the same trick on Vormir, which has other implications.
OK typing quick (in a rush... never enough time! :)
First: I can only answer you from the multiverse picture, and in that picture alternative timelines don't 'collapse' in the sense of cease to exist: there is branching where universes diverge but there isn't ever a true end to a branch or a perfect reintegration. I admit the scene with the Ancient One can suggest otherwise but I think we can understand her chat with Bruce to be her explaining the difference between a radical catastrophic branch (when infinity stone lost) versus a slight harmless branch that doesn't even look different in most ways (when infinity stone borrowed+returned).
So, your proposal: You want Bruce to go and get the stone as per film, but in the final scenes instead of what we might assume, i.e. Cap appearing shortly AFTER Bruce leaves 2012 and meeting Ancient One and saying something like "Here's the stone back, we Avengers keep our promises" instead Cap appears BEFORE Bruce gets to AO and gives him the stone -- OK so then in multiverse theory, the act of going back to that moment branches that universe again -- in one, Bruce gets the stone early, in the other he does not. This leads to two different 2023 branches, one where he returns and says "Oh it was easy Cap gave it to me, I have a good feeling we're gonna win!" and one (the film version) where he returns and says "Had to have a debate with the Ancient One, she's put her trust in us". So we don't get two hulks in one branch.
As far as I can see this doesn't create an extra time stone (versus the number of universe branches we have) it's still the case we have to put them back and all 2023 branches end up without one -- unless the Avengers go nasty and hang on to one.
I figure the narrative reason for the Ancient One's debate with hulk is that it closes the huge plot hole of "why not keep the gauntlet and get hulk to do loads of stuff with it, including fixing every sad thing that happened in the movie".
@@SimonBenjamin Thanks! I worked out the same thing last night after I posted, when I started drawing the timelines out. It looks to me like it's not possible to use this one weird trick to generate a free set of Infinity Stones (since the new 2023 timeline would still have Thanos destroying the Stones, and there'd still be timelines without Stones), but going to Vormir before the Soul Stone is taken would at least create an alternate 2023 where everyone came back from getting the Stones.
Kevin Mowery Could you post these timelines on social media? I’d love to see it
Actually I don't like to think about multiverse...it's messes everything like present is insulted. There shud be only one universe.. and through time machine we can go back in time but not the one in past come to present. We can go back in time and change present or future but it shud all tally up like integration into one story not multiple stories. Terminator 1,2,3,4 works exactly like that... Things that has to happen should happen anyway in one way or another ,if changed there shud be something the present connects with the changed past.
Captain America seen explanation is right..he went back in time , and there is no alternate cap in past..he lived with her love, and he knew where avengers finally reach .so he grew old and waited at the bench . Present and past connects..
Past thanos and army came to future- that's future travel...breaking the system actually but overall past and present shud connect . Thanos died in present... His old self came into future and dies. Events resulting to his death changed..
In men in black 3 , also past ,present and future co relates with each other . Just by time machine we witness extra events which shapes the present..
If we go back to past and prevent our birth which means we are wiping entire existence in past, present and future.. if we try to break the system, then it's like windows blue screen in time machine .. or the system should run with the extra events...which ultimately integrates into one... One way or other.. and there is always a limitation...
Yes I know so the questions in what iam said is how the rest of things run if there is change in past. Like past thanos dead , past gamora came in to future , so thanos didn't kill Loki and others for infinity stones. But we don't need to think like that's... If thanos is not there, something else should have happened to Loki . But present or future is set...
Also when Captain America goes to past and live there, the old cap is still in ice water frozen and dies in there bcos nobody go retrieve the wreckage since the old world has already got Captain America thereby freezes cap shud die in there..and the events of past Captain America didn't happen or happened without his contributions. Or he worked old and retired in present as we seen at the end scene...
If we dig up thinking like this.. it messes a lot of things... But better like I said things happened like terminator way... The end
Yeah, like I say in the video Terminator (also HP, Interstella) go for the the idea that you go back into the "one and only" past but everything you do just turns out to be consistent with the future you came from. But Endgame doesn't (and can't) use that idea for what time travel is. You can't 'borrow' infinity stones without making some change that must affect the future. (Well I guess they could have borrowed them all from times when they were just in storage and no one would know they 'blipped out' for a moment... but that would make a boring film!)
@@SimonBenjamin antman says his 5 hours in quantum realm was 5 years in reality. May be the stones just disappeared for seconds in the past .. and returned by cap . Then at present , stones will be there where it's supposed to be irrespective of thanos destroying it .. half of universe came back alive, stones too but ironman used the powers of stones from d past. . Let it be this way.
Thanos came from past to present! So he didn't kill Loki and Asgard which means at present they also shud hav come back alive and living somewer. Which we can just guess..
Then from a suitable timeline old ironman and black widow can be picked and brought back to present explaining them all.. this should be the limitation.. or they can do it again instead of mourning. past should change which sets with future. Our terminator theory can be applied 90% by making up things just the movie can't show everything.. and Captain America is d proof of it..
