He could have travelled to the future, especially to 2023, and prevented the Avengers from killing 2014's Thanos.
He didn't know he needed to travel to the future.
As far as he's concerned, he's won. He's achieved everything he set out to do, he's destroyed half of all life in the universe and "retired" to the Garden with the Infinity Stones.
He'd have no ...
Nebula didn't ask for a deed, she was just telling the story. Why did Ant-Man use "not it" in this conversation?
He's saying..."Don't choose me to go there"
Scott knows they have to go there to get the Soul Stone and he's making the deliberate statement that he doesn't want to be the one selected.
NEBULA: "A dominion of death, at the very ...
Thanos is enraged when he finally breaks the shield. Prior to his angry onslaught, we see the shield deflect the sword several times. It's not necessarily that Tony's blade is stronger than Steve's shield, but it isn't being hit as hard.
Tony's blade is made up of his nanites, which are extremely durable. For example, We also see the nanites make a gauntlet ...
Because family means more to him and Spider-Man saved his daughter, something he said he will never forget.
Overhearing, Herman Schultz showed Toomes a news report on Spider-Man saving Toomes' daughter.
Source: Vulture > Biography > Vulture's Campaign > Hijacking Damage Control Truck (4th Paragraph)
Toomes: Peter, nothing is more important than family....
Adrian Toomes is not a straight-up evil villain bent on world domination or revenge. He becomes a criminal as a means to support his family. His beef with Spider-Man is not personal; he doesn't try to kill Spider-Man because he hates him, but because Spider-Man got in the way of him running his business.
At the end, Toomes is in jail. His plans have failed; ...
That's just an easter egg for the next movie, Captain America: The First Avenger.
From this interview with director Jon Favreau,
"We introduced Captain America's shield briefly in one shot in the last film," he said. "An [Industrial Light and Magic] artist put it in there as a joke to us for our cineSync sessions, when we're approving visual effects.
Paulie_D's answer is great and I think is the most satisfying one. I'd like to bring an additional argument to the table.
We don't know if the Time Stone is able to do that. (Or, even if it was, if Thanos is able to do the trick)
By memory (I can maybe later fact check a bit more), the Time Stone is used:
1. To forward time locally
Used by Dr. Strange in ...
He did introduce himself, actually. Not by saying his name, but by showing his identification. Hence Vers' line:
We don't carry our identification on little cards.
The "little card" contained various info but most importantly here, his name, which is how Vers was able to name him when she said:
Congratulations agent Fury, you finally asked a relevant ...
One of the ways to start a game of 'tag' is for participants to shout "Not it!". The last one to say it must chase the others (i.e. he or she "is it") until someone else is 'tagged', at which moment that other person "is it".
Scott was thus expressing his reluctance to volunteer for the mission.
Did the Unsnap in Avengers: Endgame put everyone back to the place they were when they were Snapped?
It appears so.
If you look through the "portals" opened by the sorcerers' sling-rings you can see where they are coming from.
GotG & Spiderman from Titan
Valkyrie & Asgardians from New Asgard
Black Panther & Shuri from Wakanda
Wong & ...
It's called inference. Nebula says that Thanos went to Vormir with Gamora and came back without Gamora. The inference is that something happened to Gamora, and that in turn leads to the inference that there is something dangerous about Vormir: based on the information that Thanos and Gamora went to Vormir, and only Thanos came back, there's a 50% survival ...
I'm going to offer an alternate answer based on the facts the movie presents.
It's not because Peter saved his daughter:
Toomes: Peter, nothing is more important than family. You saved my daughter’s life. I could never forget something like that. So I’m gonna give you one chance. Are you ready? You walk through those doors, you forget any of this ...
once they have the time stone they can travel through time without needing the Pym particles?
There is no indication that the Time Stone allows travel through time.
Certainly the Time Stone appears to allow seeing the future and manipulation of time on a local scale...such as affecting an apple (Dr. Strange) and resurrecting the Vision (Infinity War) but ...
There are no official sources for this, just some theories and speculations:
One speculation says it can be touched, but just like the power stone, you will suffer the effects of touching an infinity stone (Maybe it kills you, vaporizes you, etc).
And that's why the Eye of Agamotto was created:
The Eye was created by Agamotto, using the Time Stone as a ...
My father is many things. A liar is not one of them.
Apparently, this is true.
I can't find a single instance of Thanos lying about anything.
Certainly, his motivations and reasoning are flawed but he holds his beliefs honestly and he's ruthless and powerful enough to follow through without the need to lie about it,.
As for the example you gave, Thanos ...
Captain Marvel throws it towards the Quantum Tunnel, which Thanos stops by throwing his own sword, deflecting it at the last moment.
No, she doesn't
Am I missing something?
Captain Marvel is carrying the Gauntlet to the van, presumably to either take the stones back herself or for Scott to do it (as he has a Time/Space GPS and she doesn't).
The real world equivalent is pilots saying "Eject, Eject, Eject", either to their backseater, or another pilot who can see that a plane can't be recovered and is using the radio to tell the pilot in it to get out. (Whatever caused the plane to be unrecoverable might have dazed the pilot--he might be functional enough to fire his seat but not functional ...
As you say, they could have handled some things differently.
By the middle of Endgame, the MCU has both time travel capabilities and the deus ex machina Infinity Stones.
So logically the heroes could have done anything and the events should not be fixed to just 1 possible outcome.
The movie simply decided to show us how it played out in that 1 timeline.
As of close of Endgame, no-one (even herself) has referred to her as "Captain Marvel".
In Captain Marvel, she is referred to as "Vers", "Carol" and "Carol Danvers".
In Endgame she's barely referenced and then only as "Carol".
The trailer for "Spider-Man: Far From Home" does have Peter Parker calling her "Captain Marvel" but it's not yet known whether this ...
This Tesseract in Captain Marvel was stable and wasn't overreacting.
However, it was overloaded in The First Avenger, that's why it burned a hole through the metal aircraft. When Red Skull and Captain America fight in the plane, they broke the hydra-built machine holding tesseract. It was already reacting in that machine and breaking it caused it to ...
It was said as part of a sentence:
Thanos: I take it that Maw is dead? This day extracts a heavy toll.
Also, shortly before that scene, Thanos
So the toll is losing people he trusted and cared about a lot.
Excellent answer by Paulie_D and I would like to add one more thing.
Although there is a considerable amount of time between Hulk's (un) snap and all the Avengers returning through portals to fight, we immediately see the effects of (un)snap with the phone call from Laura, Clint's wife.
So, she returns to the same place in her home backyard along ...
When the Avengers show up, Peter Parker says this to Tony Stark when they meet:
You will not believe what's been going on.
Do you remember when we were in space?
And I got all dusty? I must've passed
out, 'cause I woke up, and you were gone.
But Doctor Strange was there, right?
He was like,
"It's been five years.
Come on, they need us!"
This is Gamora dead:
This is Natasha dead:
Let's ignore that similar dead posture for a moment :)
There seems to be a circle at the base of that cliff. And as Sam mentions in the comments, Red Skull brings them to the top of the cliff and then explains the Soul for a Soul concept. So it appears that the offering of the Soul has to be at the circle. And ...
He was bitten by a (radioactive?) spider
...we just don't see it onscreen,
This Q&A on Science Fiction & Fantasy covers it fully but the reasoning for not including it in the movie was..
"We never talked about showing it, because the MO was always to not show anything we've seen before," Watts said. "If anything ever felt slightly ...
The team was just supportive
There are no official sources for this and we don't see a scene on-screen where they do this, but I imagine they had a discussion of where Barton should go and Bartons' request being to go back to his house, to see his family again.
We should remember that Barton lost his family for 5 years now, it's natural that Barton would ...
Nebula from 2023 time traveled with the Avengers to 2014. While there, due to the fact that she has a partially cybernetic brain, her memories became accessible to the Nebula that was already there in 2014. Similar to how 2 computers on the same network can see each other's files.
Taking advantage of this, Thanos was able to find out about the Avengers' ...
Thanos is never incapacitated long enough
During the fight with Captain America and Thor, Thanos is either on the attack or is never down long enough for Mjolnir to be placed anywhere.
Even when Captain America calls down lightning and floors Thanos for a second. At this point Cap attempts to (ahem) hammer Thanos by bringing Mjolnir down on his chest but ...
