Thanos' stated motivation in Avengers: Infinity War is to solve the problems of scarcity and overpopulation, by      wiping out half of the living beings in the universe,   which he needs all of the Infinity Stones to do. However, the Reality Gem allows him to control reality itself, which he uses in the film to      transform Knowhere into a burning ruin. This appears to be applied permanently, since it's still destroyed after he teleports away.   He uses the same power later on to show Titan as a green paradise. It seems to be some sort of illusion or vision in that case, but we know from earlier that he's capable of actually changing the planet itself if he so chooses, and presumably any other.  So, what gives? If Thanos wants to solve the problem of scarcity, why doesn't he just do it with the Reality Gem?

If I had a gauntlet with essentially unlimited power, and my goal was to help make sure life in the universe was able to prosper, then my first thought toward this goal probably would not be      to extinguish half of all life.   This doesn't directly help anyone, and it is, at best, a temporary solution, since      populations will eventually grow back.   Assuming that I am not, in fact, secretly in love with an avatar of death itself, why would I choose to      commit universal genocide   instead of directly solving the limited resource problem?  So, to be specific, my question is: In-universe, what is Thanos's motivation for attempting to do this instead of more reasonable alternatives?

I recently watched Interstellar and it was quite an amazing movie. There is something that has been bothering me. At the end, when Cooper is stuck in the time-space shelf created by the other beings (themselves/humans), he communicates with himself and Murph and he himself is the one to call himself in the space and save the earth by communicating the code back to his daughter.  My question is: If the future humans knew about the solution to the problem, why did they or Cooper chose himself to go through all the trouble to go through the space and then communicate with his daughter. Why couldn't they have done it themselves and sent the solution back to Murph themselves from the future.   Let me put it this way: "When Cooper saw himself from the shelf, why did he send himself the co-ordinates again. Why not just give Murph the solution only" Instead of sending himself the co-ordinates, couldn't he just have given Murph the solution. If the people of the future knew the solution (that they knew because that is how they survived) couldn't Cooper have just sent it to Murph from the future instead of going through the loop in space again?

In Avengers: Infinity War      Thanos snaps his fingers and half the population of the universe is destroyed.   We also know that      Thanos has destroyed half the Asgardians, half of Gamora's people and half of many more civilisations already through the old fashioned method of having them shot.   So are those civilisations immune to the effect of his actions or are they impacted a second time?

The machines turned to using humans as a source of power after the humans darkened the skies, since the machines relied on solar power before.  If the machines were smart at all, they'd realise that their strategy is unsustainable, since energy on Earth predominantly comes from the Sun in some shape or form (i.e. plants, oil, coal). So why would they not invest into penetrating or even getting rid of the clouds?  The 3rd movie clearly shows that it's possible to penetrate the cloud layer when Trinity flies through it. Although there was an issue with the lightning interference, hey, they survived! And I'm sure they can either build some sort of shielding, or even harness the lightning to their advantage.

In Guardians of the Galaxy, Ronan the Accuser possesses the Infinity Stone of Power and smooshes installs it into a large hammer he uses as a weapon.    Once it's in the hammer, he doesn't have physical contact with the stone, so how does he harness its power and use it as a weapon?

In the final fight with Thanos, Tony Stark has a struggle with Thanos to get the gauntlet off him. Later it is shown that the stones are now with Tony on his suit.  The question is, how did he get it off the gauntlet and onto his suit?

Since these plot points are fairly important for Avengers: Endgame I'm going to put them all in spoiler paragraphs.  The Avengers are able to       bring back all of the characters who were snapped in the last film, including Doctor Strange. Stark finds Strange in the final battle and asks him about what he saw in Avengers: Infinity War when he saw 1 successful outcome in 14,000,605 and whether they were living in that reality. Strange says that if he were to tell Stark whether they were in that successful version or not then it could not come to pass (or words to that effect).   Later on, at a pivotal moment,       Strange turns to Stark and indicates the number one to him. This prompts Stark to sacrifice himself. However, didn't this violate the very rule which Strange had outlined just a few moments before? Didn't telling Stark that by taking on Thanos he could realise Strange's vision mean that, by Strange's own logic, that Stark should have failed?   So was Strange talking nonsense when he said that      he couldn't let Stark in on the secret? Or is there some other explanation for what happened that I've missed?

We know that Thanos' plan was to       instantly destroy half of all life in the universe    His plan doesn't appear to apply to lower or non sentient life forms      if it did half the trees in the final Wakanda scene would have disintegrated too   Does his plan apply to all beings more powerful than himself?

In Avengers: Endgame, we see Captain America use      Thor's Hammer, Mjölnir. But not only does he wield it, he also uses Thor's powers of lightning while holding it.   Does this not contradict that      In Thor: Ragnarok, it is explained that the hammer itself is not "the source" of thunder, rather this power comes from Thor himself and the hammer is just a weapon that he can use to control it, but it isn't required.   Therefore, how can Captain America possibly control      thunder by merely wielding Thor's Hammer?

In Guardians of the Galaxy, when Ronan got stone of infinity on Knowhere and decided to not give the stone to Thanos, Korath told him that Thanos is the most powerful being in the universe. Why is he so powerful? His only abilities so far I can see are achieved using the stones in Avengers. His only visible power is strength, but without stones he would not have chance even against most Avengers in 1v1 fight.  I didn't read any Marvel comics, I've just seen the films, so are there any abilities he doesn't use in the films? Or why is he considered the most powerful being if he seems so weak without the stones (compared to Avengers, for example)?

In Avengers: Endgame      Thanos and his spaceship jump into the future and fight the Avengers.   Towards the end of the battle the ship's cannons rotate upwards and begin firing at the approaching       Captain Marvel.   This was a direct contradiction of the order Thanos himself gave when he commanded the ship to fire at the ground, regardless of whether he was hitting his own troops or not.  Clearly someone on board the ship had the authority to ignore the order and decide to fire somewhere else instead.  Who was it?  Presumably some information exists in the MCU about who is in charge of the ship when Thanos isn't on board.

At the end of The Avengers, Thor takes Loki as prisoner &amp; also takes the Tessaract, to be placed in Asgard.   But why didn't he also take Loki's sceptre with him?   It was a source of power &amp; mind control which was later revealed to be the Mind Infinity Stone.

In Avengers: Endgame...     Black Widow kills herself on Vormir to obtain the Soul Stone.   The instructions from Red Skull to receive the Soul Stone are that you must sacrifice that which you love the most.   Hawkeye didn't sacrifice anything.   He actively tried to stop it...and failed. How is this death sufficient?  edit - It is not the same as  question since I am asking about getting the soul stone out of Vormir, specifically in how they did it in Endgame. Not transferring it once it's been removed from Vormir

In Avengers: Endgame,      Present-Nebula kills Past-Nebula.   I'm confused. Wouldn't it cause a grandfather paradox?  Then how did she survive?

After being created and brought to life by a stroke of Thor's lightning      Vision casually passes Thor his hammer without even straining.   I think there was a gasp from the cinema audience at this point, I'm quite confident this was not in the comics.  Why is this character deemed worthy to lift Mjolnir?  I see three possible reasons:      The mind stone, an infinity gem, overpowers/overrides Odin's enchantment     Thors lightning imparts some of his worthiness     Vision is considered worthy by Odin    Which is it it, or is it another option?

In Avengers: Endgame, we see Doctor Strange and other sorcerers        open multiple portals at multiple locations across the universe to bring all the help they can get to fight against Thanos' army.    When last seen, Black Panther, Falcon, Wanda, etc. were in Wakanda, Wasp was in San Fransisco, Ravagers were on their Ship/Planet somewhere in the universe.  So, my first question is, how were they able to open inter-planet portals? Has it happened before?  and the second, how did Doctor Strange and fellow sorcerers know where to open the portals and look for help?

As so many fans are so fond of pointing out, the Asgardians in the MCU are not actually gods, but rather a super-advanced alien race.  Their "magic" is merely technology, their lives are limited.  Any worship of them as divine beings is either a mistake (e.g. Odin) or a deception (e.g. Loki).  I  how I feel about this, but sadly, the matter has been settled.  And yet, that's not always how it is.  The comic book Thor seems to be a genuine god, at least he was during the , which revolves entirely around gods and their godly nature.  No mention is made of technology or advanced aliens, and numerous mentions are made of "godly" factors such as reliance on worship, etc, not to mention godly feats, like being tossed straight through a moon and coming out the other side.  There are also numerous physical distinctions, such as "godblood" being a material discernible from mortal blood.      And anyone who has read that arc knows that if the gods were merely highly advanced mortals, Gorr would have brought that up.    So I'm wondering, when did this van-Daniken-esque take on Thor begin?  Was it an invention of the MCU, or is there precedent in the comics?  Is this an Ultimate/616 split, or do different writers interpret it differently within the same universe?
