Question: Did Professor Hulk bring back the original Infinity Stones with the Blip?
Question: What happened to Loki? Does this mean he's now alive?
Answer: The Loki who escaped is in a different timeline, so he will not encounter the "main" versions of the characters. This version of Loki will appear in the new series.
Question: If Captain America had to go back to return the infinity stones to balance the timeline, would he not have to go back to before Black Widow died to return the Soul Stone?
Answer: No before Black Widow died the soul stone was still there, he had to get it back after it was taken, so after Black Widow died.
I think the poster meant he would go back to the time he knew Black Widow and Hawkeye were aiming for, or a bit before for safety, then go there and wait until Black Widow died and Hawkeye got the stone, and then return it. It would be hard for him to watch, but then he would know when the right time was.
Right. But you also have to think that, having witnessed the events, and then seeing that the Red Skull is the guardian, that would have been a damn interesting scene to watch. Does Cap try bargaining with the Red Skull to return Black Widow to life after giving the stone back? On the other hand, the Ancient One's explanation was that the flow of time occurs simply because the stones are in the universe. I don't think it mattered where they are. She only wanted the time stone back because of how it was tied to the Sanctum. So really, Cap probably could have just thrown the stone in a ditch somewhere and been done with it. It also raises a question about the nature of Vormir as the home of the stone. We see the other stones were more or less fashioned into artifacts and out and about. This implies that they too were in some sort of temple in their raw stone form before being found, seized and manipulated into a real-world application. So does Vormir even have a mechanism for receiving the stone back once it's been claimed? And what is the soul stone's solo power, anyway? Reading people's fates like a crystal ball?
I don't think the red skull is really the red skull anymore, just some kind of ghost of whats left of him. However the stone gets returned is irrelevant, yes he could even just leave it in a ditch somewhere. He didn't return other stones in their original form either, except the time stone. These timelines don't continue on as the original one. According to the comics the soul stone is sentient and everyone sacrificed to obtain is has their soul trapped inside the gem. Cap and the others of course don't know that (although Hulk must theoretically know having used it) or in the MCU this does not apply. When possessing it you can control any life and read their souls (their feelings and desires). One can also revert living things back their original state (like Nebula for example).
Question: How did Thanos get to the present timeline? Wasn't Nebula left with just one dose of pym particles, which she used to get back?
Answer: It shows Nebula presenting the vial of Pym particles to Thanos, it's probable that he (or someone like Maw) was able to reverse engineer the particles so that they had their own supply to use.
Answer: 2014 Nebula would have needed the vial to power her future self's suit to get to 2023 so she could impersonate her. But Thanos would have had to re-create enough of the particles so that the time tunnel could lock onto his ship and pull it through.
Answer: She used the excess Pym particles that Tony and Cap brought back.
Is that your own personal interpretation of it? They don't show it in the movie, unless I am mistaken. And it should be Thanos to use the Pym particles to jump into the Quantum dimension, how does she having the particles in the present affect it?
Her robotic fingers seem to be red as they go into the machine, implying they're making use of the Pym particles. And they had Nebula's "GPS" unit they all wore on their hands - given Thanos' technology they could presumably have copied or adapted it in some way to work with the ship, positioning it in time and space if nothing else.
Yes that's my interpretation. The machine works differently than the suits. She did a lot of modification to it as well before activating it. She somehow managed to get an entire ship transported to the future in a matter of minutes. The only logical conclusion is that she used Pym particles to power the machine and then pull the ship through.
No. Thanos on his end, would need those particles to get small and enter the Quantum Realm. Like the others.
Answer: The directors have addressed this and confirmed that Thanos gave the Pym particles to Ebony Maw (a brilliant scientist) who then reverse engineered them and created more.
Answer: He could have gotten the Pym particles from Pym himself. Likely by force. He has Nebula's memory and saw their whole plan. But, the official answer that came out was Maw reversed engineered them.
Question: Spoiler! Given Gamora is brought to 2019 from 2014 with no ill effects, presumably just spinning off a new timeline with no Gamora in it (or Thanos for that matter, making that new timeline pretty peaceful), why can't the Avengers just go and "retrieve" alternate-timeline versions of the other people they've lost? They don't seem too worried about the timelines that have branched off due to their actions, eg. Cap going back in time (a whole other issue), Loki stealing the Tesseract, etc. They could hop back to a day earlier and basically get their friends back.
Answer: They actually do have some concern for the alternate/branched off timelines - that's the whole reason Hulk proposes returning the stones (after they're done with them) to the point they were stolen from, so that those branched off timelines won't be royally screwed with a stone (or 2) missing from their timeline (i.e. The Ancient One telling Hulk that the sorcerers need the stone in order to combat the forces of darkness). Granted, some of the changes they've made they can't do much about - not without spending more time and further interfering (Loki escaping with the Tesseract in the alternate 2012 timeline, or the alternate 2014 timeline's Thanos and co. Traveling to main-timeline 2023 - leaving alt-2014 without a Thanos, which as you say, may not be too bad). With all that in mind, I think they would be hesitant to 'steal' their friends from the past because think about what they were doing just a few days ago... trying to figure out how to unsnap the 50% of the universe that Thanos dusted. If they take their friends, who were pretty integral to figuring out how to/and carrying out the undoing of that, they would be dooming that new alternate 2023 timeline to failure in their endeavors.
Since Thanos coming from the past didn't change 2023, I don't think taking their friends from the past would change anything either. They are constantly creating new time lines/universes. However, the only people they lost were Black Widow and Vision, and Hulk tried to bring Black Widow back and failed with the stones whilst Vision lived on the mind stone, which is gone (brought back to it's own timeline). So bringing those 2 back isn't going to be happening. Who else did they lose?
Chosen answer: There's really no reason that they couldn't. Probably an oversight by the writers. I think an easy fix could maybe have been the Ancient One or Doctor Strange warning the heroes that continually altering the space-time continuum could potentially lead to paradoxes that threaten the existence of the multiverse and it's better to just let sleeping dogs lie. It would have been somewhat of a cop-out, but it would have at least addressed it.
Answer: That would be kidnapping. Also, you would be killing someone else who would need to take their spot. Either way someone dies. Are you going to keep going back and saving a fallen comrade?
Not kidnapping if they agree to it.
You assume they would agree to it. Why would they agree to it?
Because of their imminent death in their own timeline. If they get told they're going to die if they stay, but hop over to our timeline where they can still do some good, that may well persuade people. And yes it makes their timeline more uncertain, it's not guaranteed they'd choose to leave, but they may well be willing to. Regardless, "kidnapping" is a stretch.
Gamora - she's not going to die in her own timeline. Her timeline's Thanos is dead. He's not going to be there to throw her off the cliff. Black Widow - you have to explain to her that her being alive can kill countless others. If you remove her from anytime line she doesn't do the good that she has in the last Avengers movies and as a Shield agent or Hawkeye (or another Avenger) has to take her place for the soul stone. That's counter to her sacrifice. Vision - You remove him, you remove the mind stone from that timeline. Which isn't good. If you remove them from their timeline without telling them all of this, yes that would amount to kidnapping.
Question: Spoiler! At the end why would Steve Rogers pass his Captain America mantle to Sam Wilson? He doesn't possess any kind of super strength, and his only talents are flying and being a decent fighter.
Answer: This is right out of the comics. When Steve Rogers retires as Captain America in All-New Captain America #1, he passes the mantle to Sam Wilson.
Answer: Steve Rogers didn't have super strength when he was chosen to be Cap. His demeanor, personality, and selflessness earned him the mantle. The abilities came with it.
His character earned him the slot in the super soldier program - his abilities are a direct result of the now-unavailable super soldier serum. Falcon is highly skilled and trained, doesn't mean he can't do a good job as a "new" Captain America with a different skillset, but he won't have the same strength and speed.
Answer: As shown throughout the events of the "Captain America" and "Avengers" sequels, Cap and Sam are very much kindred spirits with a great deal in common. Cap thus saw him as the perfect person to pass the mantle onto.
Question: Spider-Man: Far From Home shows that people snapped back after the "blip" come back in exactly the same place they disappeared from - mid-band performance, for example, and getting a basketball to the head as a result. Have the makers of either movie expanded on the ramifications of this? Because people snapped off a flight for example, might reappear mid-air...but with no plane, so plummet to their deaths.
Answer: Kevin Feige said in a Reddit thread that Hulk specifically brought everyone back in a safe place.
Chosen answer: The makers haven't said anything that I have heard, but we can see and deduce a couple things. First, if you watch the band members disappear, then the reappearance, those that reappear are not at the locations of those that disappeared (note the two videos are 90° off from each other), meaning either some compensation happened in Stark's invocation, or the filmmakers made a mistake in their portrayal. Second, we don't hear anyone in the movie make any comment about such problems so that implies the blip-ending had a compensation for such events so they didn't happen, though to prevent calamity, not simple harm. If you take this issue to the extreme, the planet is no longer where it was, plus has spun on its axis, so if no compensation occurred, everyone would have reappeared in space millions of miles away from the planet's new location, which they didn't.
Question: Should Nebula not have ceased to exist after the other one was killed?
Answer: No - as stated in the film, timelines/realities are independent from each other. Thanos/Nebula coming to "our" timeline means a new timeline is created where they don't exist any more, but we don't follow that one. "Our" Nebula isn't affected by the actions of the "alternate", because "our" Nebula's history is unchanged.
Question: Why did 2014 Thanos bother to come to the future? As we are already aware, changing one time doesn't affect the other, and whether he knows that or not is sort of irrelevant. He could have stayed in 2014 and completed his mission, in fact he could have done it even more easily with the Pym particles he obtained without anyone ever knowing. He really had no reason to need to come forward in time. Knowing that Thor kills him in the future just means he could take steps to prevent that if/when it happens, he didn't need to act right then.
Answer: As an alternative to the above answer, another thing to keep in mind is that Thanos believes that his vision of a better world shouldn't be fought against. Finding out that an alternate universe version of himself wins the battle and then ends up having his plans ruined makes him believe that the heroes of that universe are ungrateful, and that he should help the alternate universe version of himself that died to stay the winner. He's evil. He doesn't just want to win in this universe. He wants to win in all universes.
Answer: He probably also realises that if the Avengers can get all 6 stones, stealing them all at once would be easier than trying to collect them himself.
Question: Thanos wields Thor's axe and tried to bury it into Thor's chest - is this because the axe doesn't require you to be worthy for it, or is Thanos strong enough to wield it without being worthy, or is he worthy to wield his axe and if so why?
Answer: Thor's hammer was enchanted by Odin in the first Thor movie only to be wieldable by a person who was worthy, but the axe was made later and had no such enchantment.
Question: Considering how many heroes died fighting Thanos, why was only Tony Stark given a funeral?
Answer: There's nothing to indicate that only Stark was given a funeral. While some sorcerers, Ravagers, and Asgardians were certainly killed in the final battle, they wouldn't have been personally known by all the main characters, and showing funerals for any of them would be rather superfluous in an already three-hour long movie.
Question: Why did Vision not appear in the film?
Answer: Short version, because he's dead. Bruce only brought back everyone Thanos "snapped", and Vision was killed before that. Now, whether Shuri managed to finish her work before then, somehow "backing him up" or otherwise separating him from the mind stone, we don't know as yet - it may be they somehow revive him in a future film, or the upcoming WandaVision TV series. But for now, he's gone.
Answer: Technically vision wasn't "killed." He wasn't even alive. He's a robot. Maybe they could have used the mind stone they had to try to revive him, but Thanos ripped out a good chunk of his head already. And they needed to put the mind stone back anyway.
Answer: If you noticed Black Panther's sister had just one connection left with the gem, and who said she didn't download a copy of his Consciousness but didn't finish, due to the snap and the end battle.
Question: Spoiler! Time seems to be defined as somewhat linear, with alternate realities branching off rather than changing the past of any given timeline. But if that's the case, how can Steve go back in time and stay, which should branch off a new reality with him in it, but then "catch up" with "our" reality? Seems like if he stayed in the past he'll have made plenty of changes.
Answer: The Russo brothers have elaborated somewhat: "the old Cap at the end of the movie, he lived his married life in a different universe from the main one. He had to make another jump back to the main universe at the end to give the shield to Sam." They didn't explain his jump back, which leaves the door open for interdimensional travel. They certainly implied there's a bit more to the story which might get revealed in time. But thus far we know there's an alternate timeline where 2019 Cap was running around helping people (again, per Russo interviews), not interfering with "our" timeline.
Answer: He stayed behind but didn't reveal himself or change anything whilst there. That way the future isn't altered and stays "the same." This does mean that the timeline we have been following is the timeline where Cap stayed behind and there were basically 2 Steve Rogers at all times. That can theoretically work in a linear timeline idea.
True, I think that does mostly line up. Peggy told him she got married to someone he rescued, but that could easily have been a cover story so as not to tip him off about what happens too early.
He originally had the tools to go back return the stones and then return back to his timeline. Instead of returning back right away when the job was done he just hung around and lived his life. Then as an old man used the particle to return back to his original timeline effectively leaving the different timeline he had just been living in for the last however many years. He could always return back to the the original timeline at any point. He just decided to wait.
Yeah see I don't agre to this because if he had used the particles again to go back to the future after living his life in the past he would have ended up on the platform wouldn't he? I say he just grew old and waited for that moment of his younger self going to back to sit down on that bench.
That's not possible. (a) He was in the ice for 60 years. How would he know what not to do? (b) There's nothing he could do that wouldn't change the timeline. Anything he did means someone else didn't do it from the previous timeline. A house he rented, food he ate, places he went. Even whatever fake name he uses alters history as it wasn't there before.
The point is all those things did exist, but they didn't mess with the events that occurred in the movies. So not a different timeline than the one we have been following, but the same. This can only be done if the second Cap stays out of history. I'm not a fan of the butterfly effect, it doesn't have any basis, that's why I always explain timelines in this way. An extra spoon in the dishwasher or an extra tank of gasoline doesn't change the timeline so much that it can't be the one we were following anymore. So yes, he changed the timeline, but that's the timeline we have been following.
Answer: Since Cap was frozen for 70 years, he could potentially live out his life back in that time without risking interfering with his future self's actions which would allow him to arrive back to the same point where he left. It's not too dissimilar from the first two "Back to the Future" films where Marty arrives back in 1985 from 1955. As long as Marty takes no actions to prevent himself from going back in time in that moment, then he can arrive back to the same point he left without causing a major disruption in the space-time continuum. Consequently though, since Cap married Peggy when he went back, this would effectively erase the marriage she revealed having had in "The Winter Soldier," which could cause minor differences in the timeline.
This is the point though - it's made clear that they can't change the past, just branch off a new timeline. And given we know she got married in "our" timeline, him going back created a new one, one where she married him instead. And that's all well and good, but that leaves him stranded in timeline "B", with no way to jump back to "A." That said of course there's no real reason this couldn't be hand-waved away as using Dr. Strange or other tech to cross dimensions somehow, it's just mildly annoying they didn't clarify it. :-).
Well the way they did it makes it complicated I think. The Pym particles made a certain type of time travel possible I think, a different kind than the time gem for example can do. It's irreversible, but not linear. The linear timeline is what the ancient one explained about the gems. They had to be put back in their place in time in order for the fabric of the universe to stay in tact. Only that had to be restored, but not what Cap did, or even creating alternate timelines in general (which did happen with Loki disappearing).
I feel though that since two Caps were existing in the same timeline, one of which was frozen for several decades, then the Cap that went back to be with Peggy can still end up in the same spot as long as he doesn't interfere with himself or his fellow Avengers in their "future" missions. He might cause a slightly different timeline to happen, but as long as he lets his other self play out the events as they originally unfolded, it allows that other self to be in the same position to travel back to return the Infinity Stones and then be with Peggy, rendering any branching timeline to be inconsequential because he is putting himself in a time loop. Just like Marty in "Back to the Future." Marty's actions in the past create a slightly new timeline, but he is still traveling back to 1955 at the exact same point in this slightly different 1985.
Can't compare it to Back to the Future, there was always 1 Marty in Back to the Future since he goes back to a time before he was born. The changes to the timeline in Back to the Future should have butterflied a lot away. Not sure what you mean with "still end up in the same spot" if there are 2 Caps. The Cap that went back to be with Peggy didn't have to "end up in the same spot", just stay out of history until his past self goes back. Like you say, it's a loop for him.
By "end up in the same spot," I mean the Cap that coexists with the Cap that goes back in time is allowed to play out the events from "The Avengers," "The Winter Soldier," "Civil War," etc. without his alternate self interfering in matters, thus he is able to reach the same point in time where he goes back to return the Infinity Stones and then be with Peggy, which is what creates/continues his loop.
He wouldn't be stranded in "B" if he still had his TimeGPS device (which I imagine he would've held onto). That could have allowed him to make the jump back to the "A" timeline. That device is what links/keeps the time traveler tethered/able to return to their original timeline and not get stuck. Either he used it to make the jump back as he normally would have, or he could've employed some of the great minds of the alternate "B" timeline he was living in (i.e. Hank Pym, Howard Stark (if he prevented his assassination in the "B" timeline), Tony Stark, etc...) to use the GPS's 'tether' as a way to get back to "A"
Exactly. What people seem to miss is that throughout the movie, the time travelers are creating alternate timelines, but always return to their original one. That's the way time travel works in the MCU.
That's a good point - if they go to the battle of New York and make any change at all, that's a new timeline which they're technically in, but they can still return to their original one without any problem. That new one then carries on without them.
Answer: What's interesting is that during Civil War when Peggy dies and people are carrying her coffin, there is a white haired man of Steve's build carrying one side, but it never shows his face. I believe this is a little Easter egg to show he was there all along.
Answer: Remember Cap took three vials of Pym particles. One for himself and Tony and another for this reason.
Answer: Theory 1: The MCU as we know it is a product of Captain America going back in time and returning the stones. Theory 2: the older Captain America is from another timeline. That's how he got a new shield.
Question: How did Tony know where to find the Tesseract?
Answer: Both Tony and Steve knew that Howard Stark recovered the Tesseract in 1945. SHIELD were then conducting research on it. They knew it was likely stored in the secret shield facility in New Jersey. They weren't 100% certain, but it was their best chance of locating it and at the very least they could obtain additional Pym particles to try another time if necessary.
Question: Why didn't Hulk use the Infinity Gauntlet to snap Thanos and his army? He was able to snap everybody that Thanos killed and survived, so he would have survived another snap.
Answer: The gauntlet fell off after his first snap, then Thanos arrived from the past and destroyed the building, separating them. Hulk never got near the gauntlet and the stones during the ensuing battle, so he didn't have an opportunity to try a second snap to destroy Thanos.
Really what they should have done was pulled the stones off the gauntlet and separated them again, and not run around with a fully assembled and powered up Gauntlet for Thanos to grab.
I agree.
That would mean they had to touch them, and nobody besides Hulk, Thor and Carol could touch one without dying.
Ordinary humans can't just grab an infinity stone. Even when Thanos takes the power stone out of gauntlet you see it start to destroy them.
Only the Power Stone has been shown to kill normal people who try to hold it. Hawkeye literally held the Soul Stone in his hand in this movie.
Because he made the necessary sacrifice. Anyone else touching it, big problem. Could be an exception though. The power, reality and space gems have been proven to be untouchable and killing anyone who does (with exceptions though). Time gem is very carefully handled as well so I wouldn't touch that one either. Mind gem, who knows?
I don't recall the Time Stone killing anyone who touched it. The only example I can think of was the Red Skull presumably being killed when he handled the Tesseract, but was in actuality teleported to Vormir. The Reality Stone has a will of its own, so someone could feasibly handle it without harm. You're wonder about the Mind Stone is correct, as no human character was shown in any movie to have handled it directly. Overall though, I would say that I disagree with someone trying to remove a stone from the gauntlet, as one stone could easily be lost, and Thanos could still kill every hero at the battle even with one or more stones missing.
The reality stone attaches itself to anyone touching it like a parasite and slowly kills them. I'd say it's a bad idea to touch it. As for the time stone only the ancient one and Hulk actually touched it and there is reason Strange handles it carefully and without touching it. As for the Red skull, don't really know if he is really alive on Vormir. Who knows what the tesseract did to him?
Whether or not Red Skull is still alive is an interesting topic, but either way, I'd argue that while the Tesseract transported him, it itself is not what made him in his current state, but rather his curse to guard the Soul Stone and the planet of Vormir itself, as it is a dominion of death as Nebula stated.
Question: *Spoiler* After Tony died, why didn't anyone just use the time stone to bring him back? We saw Thanos do this with Vision in Infinity War so not sure what was stopping anyone from doing the same.
Answer: Vision was killed by Wanda, and Thanos just rewound that "bubble" of time so he was alive. Tony on the other hand was killed due to his internal injuries, caused by using the gauntlet. Rewind time to just before he died, and he'd still die again, because of the damage. Rewind it to before he even used the gauntlet...and he wouldn't have used the gauntlet, leaving Thanos and his army alive and kicking. That's of course assuming that the time stone can even alter events which have been caused by all 6 stones combined.
I have a further to this question however. The keeper of the Time Stone is Dr. Strange, and has been shown to have adept knowledge in it's usage since he first acquired it. They do have to return the stones back to the timelines where they originally got them to keep the time lines from really getting screwed up, meaning the stones in their time would still have been destroyed by Thanos 5 years prior. However, what exactly would keep Dr. Strange, someone that powerful and knowledgeable of the Time Stone, from using it to reverse Tony at that point? As demonstrated in his solo movie, he can manipulate time around a single object... i.e. the apple he makes rot/eaten/and whole again without affecting anything else around it. So why can he not do the same for Tony, unless undoing that would make it so he never snapped, but that would only be in that little bubble like you said. It could create a paradox possibly, but this question brings up this issue as well.
The snap caused his death. If he reverses time, he dies again. If he goes back further, he undoes the snap. There isn't a little bubble. The time stone can't be that powerful to undo the ramifications of the snap.
Question: The beginning of the film shows that Clint is still on house arrest. Ant-Man and the Wasp showed that Scott's house arrest ended well before the Snap. Aside from being sentenced at a later time than Scott, is there any reason why Clint would be given a longer house arrest than Scott? Wouldn't his time working for S.H.I.E.L.D. make it more likely that he would have got a more lenient sentence?
Answer: Nothing was said about what Clint's sentence was, but we do know Scott took a plea bargain and therefore may have got a lighter sentence. And the fact that Clint worked with S.H.I.E.L.D. might have given him a longer sentence since he should have known the importance of following the Sokovia Accords. The out-of-universe answer is because the writers needed to show why Clint wasn't in Infinity Wars.
Question: Why wasn't Fury in the final battle? Or Hill?
Answer: Being regular humans without powers or highly advanced technology, they may not have been able to fight properly against Thanos' forces.
Neither did the Asgardians.
The Asgardians were there and they are superhumans.
The average Asgardians are all established to be vastly stronger, more powerful and faster than humans. Their soldiers even more so.
The remaining Asgardians were there.
Answer: Spoilers! Given what we see in Spider-Man: Far From Home it may be that they were offworld doing other vital work.
Answer: Since any reason given would be speculation, the easiest explanation is that they had something else to do in this, the one and only future where the Avengers won against Thanos.
Question: When Hulk has the Infinity Gauntlet, Tony tells Hulk to snap back everybody that Thanos killed. Why not just snap Thanos and his army first and then snap half the world's population back to life? If Thanos had been snapped first, then they wouldn't have to worry about him anymore.
Answer: It's important to remember Tony's motivation as well. He was reluctant to even try because he now had a daughter and didn't want to risk losing her or Pepper. When he reminds Banner, he tells him not to try anything other than bringing everyone back in the present because he doesn't want him to rewrite history, potentially removing his daughter.
Answer: No guarantees they'd get two goes at it. They likely figured it was more important to bring everyone back and hope they can take on Thanos conventionally. Although if I remember rightly, they have no idea Thanos is back before they snap anyway - last they heard they'd chopped his head off, end of story.
Question: At the end when Gamora and the Good Nebula are speaking, Gamora asks Nebula what happens in the future and Nebula responds that she tried to kill her many times, but they eventually became friends. Why didn't Nebula bother to tell Gamora that Thanos killed her to get the Soul Stone. Seems odd that she left that out.
Chosen answer: Nebula already alluded to Gamora being killed by Thanos earlier when she said something along the lines "You know what he does to you?" In this scene in question, Gamora is already disillusioned with Thanos and frees Nebula from captivity to battle him, thus it's not necessary to show the audience Nebula telling Gamora what Thanos did to her. She may have told her offscreen while they were on their way to find the evil Nebula.
Answer: No, his snap simply restored all the people Thanos' snap eliminated. They discuss it before he snaps. Tony reminds him to not try to do anything other than bring the people back.
We don't know that's all he did. Considering the Ancient One's warning that removing a stone for one's universe could have disastrous affects on that universe. One would think he would return the stones.
DetectiveGadget85
She was talking about removing them from the timeline, nothing about destroying them. According to the comics when the stones are destroyed the powers they represent will be made physical again in a different way. This does not happen when they are removed completely, since the power inside (the energy) cannot be reassembled again.
lionhead
Destroying the stones almost killed Thanos. Hulk would not have been able to bring back half the universe and the stones with no further impact.
We do know. As stated in the answer, Tony and Hulk specifically discuss ONLY bringing the people back. Since it's stated in the film, we can say with certainty that's all he did.
As stated in the film, he also tried to bring Natasha back who wasn't one of the half Thanos snapped away, so while unlikely, perhaps he did try more.
