The Hulk is the one that snapped everyone back into existence. The trillions of people that Thanos killed were brought back, by the Hulk.
The Blip was the resurrection of all the victims of Thanos' Snap. It occurred after the Time Heist, in which the Avengers had taken Infinity Stones from different timelines to assemble the Nano Gauntlet, which Bruce Banner used to restore half of the universe's population.
during the final battle when everyone who thanos snapped away, Dr Strange, spiderman etc come back from Titan via Dr Strange's cosmic sparkle rings.
This sent the galaxy into a state of chaos, and even after the Avengers killed Thanos a few weeks later, they could not immediately reverse his act. After the five-year time jump in Avengers: Endgame though, the Avengers eventually managed to bring everyone back safely and defeat Thanos again.
The Blip occurs at the end of the film in Wakanda, where numerous characters are blipped, including Bucky Barnes, Nick Fury, Maria Hill, Wanda Maximoff, Peter Parker, Stephen Strange, T'Challa, Sam Wilson, Peter Quill, Groot, Drax, and Mantis.
The Asgardian Son of Odin was extremely close to ending Thanos at the end of Avengers: Infinity War. After gaining the powerful weapon Stormbreaker, Thor becomes the wielder of the most powerful weapon in the universe. Stormbreaker is capable of killing Thanos outright, and only Thor is currently worthy of wielding it.
After Tony snaps his fingers while wearing the Iron Gauntlet, he's transported to a mysterious place. As he tries to gather what's going on, he hears a voice call out to him. Tony turns around to see a grown-up version of Morgan, played by Langford. Tony quickly realizes the young woman is his daughter.
As Thanos had soul stone, he viewed Tony's soul. That's it.
Tony Stark asked, “How many do we win?” Doctor Strange replied, “One.” The 'one chance' scene in Endgame is Strange reminding Tony of that single scenario, and Tony realising that the only way for them to win is if he sacrifices himself.
He felt sad, after all he had to kill his own daughter. But not regret. The “Snap” has always been his goal. And now, he finally achieved it.
He didn't double the resources in the universe because that's not what he's trying to accomplish, and also because he's an unhinged, sociopathic supervillain who is basically on a holy crusade. Thanos' plan only has to make sense to him, and in terms of fitting his character, it's perfect.
On Earth, the Snap led to a five-year period in which the world fell into societal collapse and many countries abandoned their national borders. In 2023, the victims of the Snap were resurrected by the Avengers, after they went back in time to alternate timelines to acquire their own set of Infinity Stones.
Why wasn't Gamora at Tony Stark's funeral? Gamora's absence from Tony Stark's funeral in Avengers: Endgame can be attributed to a simple fact: there was no reason for her to be there. The Gamora we saw in the Guardians of the Galaxy movies and Infinity War is dead and never met Tony.
But in Avengers: Infinity War, the Thanos who was on the hunt for infinity stones said that he respects Tony Stark. This scene in the film shocked everyone. It happened during the fight in Titan when Iron Man attacks Thanos. The might villain tells Stark that he respects him.
Endgame might have been the end for many characters, but was clearly never the end of the franchise; new projects had already been announced before the movie's release. The MCU is also unlikely to end any time soon, as it remains a huge financial hit and future projects are planned.
Probably, the user may probably see the one he loves the most, or the one who was sacrificed for the Soul Stone. Gamora fulfills both the criteria. She was the one Thanos loved the most, also she was sacrificed for the Soul stone. Probably this is the reason Thanos saw her moments after the snap.
Why does Thanos respect Stark? Because he sees himself as noble, and is immensely driven, and he sees these things in Stark as well. Both are clearly willing to do anything, willing to sacrifice anything, to fulfill their goals, to see their missions through.
Thanos is trapped in a pocket limbo of stasis by his son. Thanos is freed by Namor and was among the villains that joined his Cabal to destroy other worlds. Thanos later meets his end on Battleworld, where he is easily killed by God Emperor Doom during an attempted insurrection.
The stones were destroyed in the Marvel timeline, but are still intact in the parallel timelines after Captain America restored them.
His solution was simple, fair and brutal: He would kill half the population by random drawing. The rich and poor alike would be killed according to chance, and the rest of the population would have a chance to live in a world of plenty. The other Titans didn't go with his plan.
As per the user, the director of Avengers confirmed that Thanos was most scared of Iron Man. “Not because of his strength, not because of his power, not because of his power, but because of his suit,” he added.
However, Ultron, who was fascinated with the Stones, effortlessly killed Thanos by cutting his body in half with a laser beam from the Mind Stone and obtained all the Stones for himself which turned him into a cosmic being.
Thanos didn't lift Mjolnir, Captain America did
With Mjolnir's worthiness enchantment resulted in Thor being able to lift the hammer only if he is considered to be worthy, but likewise, the enchantment is not discriminatory in nature, and anyone who is deemed worthy is able to lift the hammer.
The kid is none other than Harley Keener, as portrayed by the fantastically named actor Ty Simpkins. We were first introduced to him when he somewhat randomly crossed paths with Tony during the course of the third Iron Man movie, when the superhero found himself without working armor in scenic Rose Hill, Tennessee.
