Hold on just a minute

Never thought about Cap meeting the Red Skull again.

what about the red stone? They would suringe it into that girl again? And the purple stone would be returned to whom?

Why was 2014 Thanos so much stronger than 2018 Thanos, who had the Infinity Stones. Thor almost 1 shot 2018 Thanos, while 2014 Thanos was easily holding his own against the original Avengers.

2014 Thanos traveling to the futute caused 2014 Thanos' timeline to split where none of the shit done by Thanos happened.
It's LITERALLY Dragon Ball time travel and you retards still have trouble understanding it.

Captain America's ending contradicts the entire fucking "it's not exactly time travel, guys!..." plot they tried to spin to us.

But again - it's a movie for 12 year olds where a super glowing Lesbian destroys a city-sized spaceship in 4 seconds.

>reverse damage to the timeline, its all one smooth branhc again.
How do you know that? 2014 Thanos was killed so sure there's no IW in that timeline, but that doesn't mean something utterly fucked couldn't have happened. They returned the stones there so someone could've collected them and wipe out the whole universe.

>Novikov Consistency Principle
This. Closed timelike curve is the only time travel that makes sense. DBZ time travel is for retards and not only that, it's just normal multiverse hopping. They should've called it that instead and maybe then it wouldn't be so shit.

>It's never been done but let me tell you how it can't be done
Sciencefags are so annoying I love it when your stupid little theories get proven wrong

>2018
>go back in time and get all infinity stones because you know where all those are
>come back to 2018
>go back in time to the same place 12-24hr before you got your stones
>now you have 2 sets of stones

so that's why they're called "infinity" stones huh

>infinity war scarlett witch (with vision's help) gets BTFO by glaive and proxima

Haha, that would have been a good after-credit scene.

They used the time travel devices in 2012 New York to go to 1970 without the platforn, it's not fucking rocket science.

It has, brainlet. They are literally part of general and special relativity’s theorems. Novikovian self consistency principles are the only way to logically reconcile the implications of the mathematics.

It's honestly like you people just read summaries of the movies you love to hate.

General relativity isn’t fantasy. In fact only 100 years after it was formulated have we been able to visually confirm one of its propositions (black holes). And general relativity’s principles are used every day in astronautics including your GPS satellites which constantly have to be synced with Earth time because they go slower from their orbit and speed. Relativity is the most consistently proven theory in science. You’re the brainlet here, capeshit coper.

2014 avengers was relying on the stones to do everything after he got them. He even gets rid of his armor at the beginning to emphsize this. He got blindsided by thors weapon that was made of an ultra rare material that could absorb the beam.

2014 thanos is still in full warlord mode relying on his actual skills and gear. Thors weapon is strong, but if he cant hit thanos with it then its useless. And Dr strange was not there to help. The only time we see thanos beaten legit is on titan and it was because of strange.

Gay

only in the 2014 timeline. they stated they are different timelines

Travel to the past is impossible in general relativity

Just say theyre in different head canons and it’s all made up. Same shit.

>Relativity is the most consistently proven theory in science
While I agree with all your other points, let's not go that far lol.

Go ahead and give me a citation outlining time travel into the past. Not time dialation, actual traveling to your own timeline and meeting yourself.

Time travel would be possible with faster than light drives in GR tho.

brainlet here
if it's proven time and time again why is it called "theory" and not "principle" or whatever

No it isn’t. It’s possible. Wormholes are one way.
en.m.wikipedia.org/wiki/Time_travel#General_relativity

Because a theory is an explanation for something, not that something itself.

Also, we cannot know 100% of everything and therefore it will always be a theory.

It doesn’t happen in Thanos timeline but it already happened on the main one

And principles are more like axioms that theories are built around. Principle and theory denote two different things.

People who argue over time travel are actual autists.

See first sentence ofAnd if you have issues with wiki, feel free to google it yourself and read the tons of articles written for brainlets like yourself. Enjoy.

>in the process of trying to invent time travel, they accidentally create a machine that is capable of aging and de-aging people
>thinking this literal fountain of youth/insta-death machine will not cause plot holes in future movies
bravo Markus & McFeely, really was worth it so you could make a joke about Ant-Man going pee-pee in his suit

If he went back to 1945 he'd be about 110 in 2023.
He probably stayed with Peggy till she died in 2016 then came back, meaning he'd only be 103.

I agree. Anyone who argues that capeshit time travel isn’t shit based off the simple facts of reality, is an autistic retard.

Do you know a dude named johnny neptune by any chance

SEETHING tripfag

Kek

No why would I.

because you're gay

Sounds like you’re the one that’s seething, little buddy. I’m just stating facts here.

Well, he had armor and a weapon that’s stronger than vibranium this time. Maybe that helped

At least I’m not a retarded capeshit gobbling mutt like yourself.

It is. That is also a fact based on how many times experimental testing has proven it right. There have been more experiments done on relativity than any other theory.

Also they brought a stone back instead of the actual tesseract. And did cap have Loki’s staff or did he just bring back the stone?

Yet you are in a capeshit thread, trying to make sense of it with 5 posts a second
Take your meds

This is definitely going to be the new
>Why didn't he just make more resources?
except somehow even more braindead because the movie doesn't imply but ouright states TWICE how time travel works.

It's alt-verse shit IN spite of Marvel's attempts to claim otherwise, bringing an alt-verse into it is the only way the story's possible.

How did Thanos send his ship to the future without any Pym Particles?

I can be wherever I want for my entertainment. Unfortunately for you, I seek entertainment from brainlets in capeshit threads today.

The very first paragraph mentions that Hawking said it would not be possible. Do you have some knowledge that stephen hawking didnt have?

There is a new timeline where Thanos stopped existing in 2014. The directors have confirmed alternate realities due to time travel.

You are correct.

We've never had proof that those things exist & can be done.
Quantum computing however has done backward time travel . They sent qubits to where it was. But that's more like throwing a ball to the wall, watch it bounces and compute/predict its backwards trajectory. Not actual time travel but close enough.

Oh shit, I didn’t think about that. Why not just de-age old cap?

feast, then, your highness

That is a conjecture that is yet to be proven because it cannot be proven without a unified theory of quantum gravity. The problem with closed timeline loops without causal violations to the outside universe is the problem of energy density and energy pileup, which essentially would require infinite energy and infinite universes. It’s essentially the multiverse theory, which again, is yet to be proven via all the string, M, and other quantum gravity theories which still remain to be tested.

LMAO stay mad tripfag

The reply calling you gay was my only post in this thread. I've never watched capeshit.

Yeah, no. There's teachers doing experiments to teach students about any other branch of physics that outnumbers the expensive relativity experiments every day.

But of course you won't count those.

Because he didnt want to. He wanted to live a life with peggy and find peace then die.

We’ve never had proof of black holes until 100 years later and we got a photo of it. General relativity’s predictions have been true every time and we have yet to prove it wrong.

>shits onto his keyboard
>believes he is making a profound statement
The absolute state of tripfags

Endgame is the endgame. Everything forthcoming is post-script season. Just make your peace with the franchise now.

You're free to pretend that happens and Cap soldiers on under a new identity. But maybe he just wanted for his life to end after he got all the happiness he fought for.

Cope more brainlet.

Wrong. They fucked up two timelines.

Loki escapes with the space stone.
Thanos is dead before executing his plan.

It creates alternate timelines; they can't alter their present by changing things in the past. That's why they needed to return the stones. It would avoid creating these alternate timelines, and screwing over everyone in them. They could have technically just said fuck it and it wouldn't affect them at all, but would have created like six branching timelines.

No but I know Jimmy Neutron

The more important question is, are they going to give serum (or whatever alternative) to Falcon? He's just a guy.

Problem with MCU being so fixated on the cosmic shit is that every race is presented as much stronger than humans and then they're fought off by regular humans. Just give everyone Cap steroids damn it.

>thinking this wasn't 100% intentional

You nerds are forgetting the oldest trick in comics: always leave the door open to bring back a character. Now that we've established multiple timelines, there's all sorts of room to bring back everyone who's died or retired in the last two movies without undermining the resolution we gave them.

In other words

You might say

No one is ever really gone

Coping would mean it was actually threatening to existing theories. No one fears firmament theories because they are easily proven wrong and have no application to the real world. Only head canon.

Makes me wonder how UBW would of ended up if Girugamesh used his armor.

Why didn’t Doctor Strange use the Time Stone to return Tony to a pre-dead state? Thanos was able to do it with Vision

If Susskind says human time travel into the past and wormhole traversal are impossible, then that's good enough for me and you're a tremendous faggot who needs to go back to l*ddit.

Thats not how science works, dumbshit

And in all the other timelines they visited, the stones are no longer mint in box, so their future, while roughly the same, will change as well. At least they'd not fucked up because building blocks of the universe have gone missing.

They didn’t in the comics

>argumentum ad autoritas
Brainlet. Try actually going to the wiki link about timeline protection conjecture. Even there it tells you the same thing. You people need to read before you speak.

He doesn't need any serum as he is already peak human... He's black. Superior genes.

>mad enough to reply
Struck a nerve little guy?

Cope

I dont think they have any serum. So falcon getting the shield is retarded. His suit is better and a shield would just get in the way. He could even get vibranium wings if he wanted from wakanda.

Because RDJ contract ended.

they reverse engineered many more pym particles from the ones found on Nebula. They had time to do this because they could just pick what time they wanted to arrive in the Avengers reality anyway

Only in that offshoot universe, not in the main one.

I wonder if Cap and Red Skull said anything when Cap returned it.

"Oh......hey"
"Hey"
"Here"
"Ok, thanks"
"K, bye"
"Bye"

Sure but humans are actually shit compared to aliens. And yeah I don't see how the shield fits his MO at all.

Go back in time and tell yourself what argumentum ad autoritas actually means before you embarrass yourself.

He literally gets vibrainium wings from Wakanda in the comics

It means argument to authority. Which you used. If you think it’s wrong because it’s supposed to be spelled “autoritad” you should learn Latin and know the difference between a specific object and a general object.

>relativity proves backward time travel
brainlet or bait

It does the exact opposite. You can only get closed timelike curves by twisting the EFEs into nonsense.

Why did Tony genocide Thanos's slave army?

LOL keep trying tripfag you'll make it one day

Wrong. Relativity shows the existence of wormholes which can indeed loop to a point in spacetime that allows you to have the cause come before the effect.

Gamora got dusted as well right? She was still with Thanos then

*effect before the cause

I always wondered why every avenger didnt have a vibranium suit like BP for endgame. It shouldnt take more than a few days and they had 5 years to turn every avenger into jaggernauts. Is there something from the black panther movie about why they dont? I havrnt seen those or antmans.

Wrong objection, try again.

The same considering that Gil never uses his helmet. I'm not even sure if he owns a helmet.

Lol why don’t you tell me more about how much you love authority, brainlet.

They were not slaves. The chitari hivemind signed on with thanos willingly.

>Relativity shows the existence of wormholes
Fucking kek.

Using a nonsensical stress-energy tensor that doesn't correspond to anything real. No one really takes that shit seriously. If I plug negative or imaginary mass into Newtons equations I can get perfectly valid mathematical solutions, but does that correspond to any real phenomena?

Non sequitir ;)

Inconclusive. You can see Peter Quill searching for her on his screen at the end of the movie. She'll probably show up in GoG3 as a badguy.

Before the black panther movie Wakandans didn’t want to help anybody, not even neighboring African villages. T’Challa gets a change of heart after realizing that Killmonger (the villian) was created because Wakanda not giving a fuck about anyone but themselves.

Post snap I’m sure Wakanda was still recorvering after losing so many people and weren’t able to help anyone.

You can't change events in your own timeline. They made that clear with the killing Baby Thanos example.

He got them from Nebula.

Why would she be a bad guy ? She wasn't loyal to Thanos in this timeline either, otherwise she would have gotten dust'd

Deal with it brainlet. That nonsensical stress-energy tensor can be anything from a black hole to some other source of intense energy we haven’t found. Combined with our discover of the higgs field and our potential ability to manipulate it, there is more than enough sense you can make for that tensor.

The theorems allow for them. We haven’t visually been able to confirm it yet. Just like the blackhole, which only happened 100 years later.

Loki never got away because since they went back to the 70s, it corrected the interfering they did in 2012. They effectively never screwed in that period and caused Loki to get away

Iron Man snapped his Disney contract out of existence.

so it was some john titor kind of deal?
how did they take the stones back to their exact same universe? did they save the "universe coordinates" or something?

Because in the source material she flips back and forth between being an an ally and an adversary multiple times. She clearly doesn't feel comfortable hanging out with Quill & Co., so she might be going off on her own now. Who knows.

I never understood why everybody didn’t have their own Iron Man suit. Tony made 35 different suits in between Infinity War and Endgame. He could have made everyone their own specific suit like he did for Spider-Man.

Suri made the Black Panther suit and she was snapped away

Yes, actually. That was the whole point of their research before launching the mission.

Time travel clones are always doomed. Did you learn nothing from Futurama?

No she betrayed Thanos for her sister

so if I get my math right, they only really saved 2 universes from Thanos faggotry: the one shown in the movies and that other one where past Thanos travelled to present
rest of the universes remain snapped
is this correct?

But Nebula only had enough Pym Particles to send herself back.

>nonsensical stress-energy tensor can be anything from a black hole
Black holes are a nearly trivial solution to the EFEs and one of the first things that were worked out. They are not "nonsensical" at all and don't require turning that tensor into gibberish, unlike wormholes, "warp drives", and other bullshit like that. Relativity does not allow time travel or FTL (same thing) and your brain is drunk on pop sci.

We see ayo working with the remaining avengers at the start of endgame though, so they are clearly still involved. Do you need the BP powers to be able to move in the suit? They made an vibranium arm for bucky instead of a suit and he even has serum

Thanos is an advanced alien. He can examine them and make his own.

>how did they take the stones back to their exact same universe? did they save the "universe coordinates" or something?

That's where the hand-wavy stuff comes in. They must have, otherwise Cap wouldn't have been able to return the stones. Just accept it. :^)

I didn’t call blackholes nonsensical. I was using your own words because you called it nonsensical. You simply don’t have the sense in you to figure it out yourself, brainlet.

"If you travel to the past, the past becomes your future, and your former present becomes the past, which can't now be changed by your new future." - Hulk

It's a confusing way to say it but what he's saying is "you can't change what already happened." Even if you kill Baby Thanos or if you steal the stones from the past, the Thanos in the original timeline would still be alive to kill half of all life.

Yeah. That's why it was a multiverse heist and not a time heist.

Problem is, the whole movie is a dbz type of time travel but in the end with old Cap it's LOST type of time travel. For fuck's sake. And no, he didn't travel to their time when he got old or he would've come out on the machine and not sit there on some bench.

I suppose you could really stretch and say ANOTHERTIMEMACHINE and then he walked to the park from wherever that machine was but you know, Occam's razor and all that and there was no indication of that.

Exactly. Spiderman and pepper get their own suit, but why not black widow or others. Even cap would be enhanced by all the utility a suit would have like flying and sealed environment.

Aka multiverse theory

A different universe is created when you change something in the past and don’t fix it. So how many different universes were created?

There’s a new universe where Thanos disappeared in 2014

There’s a new universe where Loki escaped with the Tesseract in 2012

What other ones are there?

Ohhhh. I thought his dad had one too.

If everybody had a vibration suit the audience would realize BP is a really lame character, powerlevel-wise

Each of them have a version where the infinity stones are returned and ones where they werent.

>There’s a new universe where Thanos disappeared in 2014
>There’s a new universe where Loki escaped with the Tesseract in 2012
Think those two are meant to be the same. They travelled to the same "past" universe for all the stones, no?

>I didn’t call blackholes nonsensical.
No, you conflated wormhole solutions of the EFEs being nonsensical with black holes solutions being nonsensical because you don't know what you're talking about and don't know how to read my posts.

but cap put it back in the 70s where they got it so Loki would still get it after they failed to get it in 2012

Technically there should be a split for everyone of them. Doesnt matter that they travelled from the same future point.

Even without the suit BP is on the level of cap, maybe better, and everyone likes cap.

Only real life theory that explains time travel as seen in endgame is the many worlds interpretation of quantum mechanics. There are no causality paradox concerns because changing the past doesn't change your future, because you're never really traveling to your own past, you're just traveling to a universe that is nearly identical to your own past.

That’s like saying “because America gives relief aid to other countries we should give them tanks and fighter jets that they have full control of”

The time travel is splitting.
There is no "corrected the interfering" and "effectively never did X".

I was expecting Cap to pull out Tony’s MK-50 armor that Tony gave him in the beginning of the move when he was fighting Thanos. Imagine Captain America wearing Iron Man’s armor while holding Thor’s hammer

Not the nano suit that T’Chala had though. Suri made that one. Their fathers was just a regular suit

No, you called the stress energy tensor nonsensical because you’re hyperbolizing your own brainlet perspective that wormholes are impossible when we already have something that can fit the mould of that stress energy tensor such as black holes among other propositions I made. Cope more brainlet.

>Only real life theory that explains time travel as seen in endgame is the many worlds interpretation of quantum mechanics.
Basically this. Many World is almost certainly unfalsifiable but it fits nicely in with the laws of physics rather than straight up contradicting them like other forms of time travel.

Every time you change one thing it branched off to a new universe according to Tilda Swinton.

Your metaphor is broken.

Technically now there’s a new universe where everyone in Hydra thinks Cap is a secret Hydra agent now.

Damn. I bet even the writers forgot about that, cause I completely forgot.

That branched timeline is without its own Thanos but it doesn't affect the main timeline. It's literally as simple as that.

It's a plot device and honestly I'd rather not, especially considering how much of a slog it was in IW with its own expositions already.

Only shit I can remember that just happens with not even a slightest bit of exposition. They definitely should have showed Cap returning the stones and a scene with Red Skull.

Where the fuck did you learn GR from?
Wormhole requires negative mass matter for it to exist and that shit is fictitious. There's littetally no evidence nor anything suggests it can exist in this universe.

General relativity only proves it is "probably impossible but you never know" .

It's already confirmed he lived in an alternate branch/timeline with an alternate Peggy and returned of his own accord to his original timeline to hand down the shield and mantle of Captain America.

Turns out you couldn't understand a movie for 12 year olds.

>Where the fuck did you learn GR from?

The Russos said that Cap returning the stones are practically a story of their own and they infer that he basically became a cosmic traveler, hence why they didn't go too heavy on it.

Russo's already confirmed Cap lived in alt universe until he got old.

Damn you’re stupid buddy. Try learning your own language.

Red flag that the writers know how stupid the shit they wrote is, but they decided to just fuck it.

Loki did get away with it, but he would ultimately give it to Thanos anyway. His tv series will probably start with him appearing out of a portal.

Says the tripfag who thinks "it's" is a possessive pronoun and thinks GR predicts wormholes if you butcher it enough.

They said he went back his own way early on and sat on the bench, not through the machine they used.

In the VN all Shirou does is cut his arm off at the bicep, and his armor doesn't cover that part of his body anyway.

Failed at what? You haven't made a single substantive point or argument in this thread and it's entirely shitposting and doubling down at this point.

Failed at everything:
1. Proving that GR states time travel is impossible (it doesn’t)
2. Being able to support your own arguments about stress energy tensors required and wormhole solutions being nonsensical.
3. Understanding simple English

There are ways to avoid a paradox. They just went with multiverse time travel. So there are two Thanoses from different timelines: one who got decapitated and the one who got dusted. It's not that hard.

I thought they were very clear in establishing time travel as a mcguffin and to not think too hard about it because it's a comic movie and they can do whatever they want to make the plot work.

Exactly. They used the cheap multiverse theory version of timetravel to make it easier for them to write themselves out of a corner.

Because theory in sciencese is not the same word as theory in plebspeak
Theory in plebspeak is hypothesis in sciencese
Theory in sciencese is a hypothesis that has made predictions that nave been independently validated by experiments and evidence by multiple sources

It doesn't mean it's only a thought
It's confirmed as fuck

I personally don’t consider the Novikov consistency principle that sophisticated to be honest. It’s simply just logical and realistic. It’s like saying me complaining about a movie that takes place on earth having green skies because they’re not blue is “sophisticated”.

The "take the stones and bring them back to correct the timeline" thing they explained is bullshit.
Everytime they moved back in time they created a new timeline and cap created additional ones when he returned the stones.
