Whether it be in the comics or in the movies, Thanos's Snap was one of the biggest events in Marvel history. Thanos's desire, regardless of his reasoning, to destroy half the universe fueled him in his quest to gather the Infinity Stones (or Infinity Gems in the comics) and gave Earth's mightiest heroes a reason to team up and battle the Mad Titan.

Fans all the over world thrilled at the moment Thanos snapped in Avengers: Infinity War, just like comic fans had almost thirty years before in Infinity Gauntlet. However, as great as the moment was, not everything about the Snap makes sense. Let's take a look at some of those things.

10 Conservation Of Energy

While the Infinity Gauntlet in the comics made Thanos into what amounts to a god, the one in the movies wasn't nearly as powerful. For example, in the movie, Thanos with the Gauntlet can be hurt, while the comic version couldn't be harmed.

Onto the point - what happened to all the energy of the dead people in the movies? In the comics, Thanos could easily do away with it because he was essentially a god. Somewhere in the cosmos, there had to be energy beings, so what happened to the energy they were made up of? What terrible things happened because of it?

9 Half Life?

So, Thanos killed half of everything in the universe, but how far down the food chain was he going? Again, the movie Gauntlet was nowhere near as powerful as the comic version, so there's a good chance it didn't target everything.

While we know that species like birds were affected, what about insects? Or the living gut flora inside of every human and the alien equivalent? What about plants? Did Thanos snap away half the food supply of planets as well? This provides us with a nice segue into the next entry.

So, let's say half of all plant life disappeared and that plants on other planets serve the same purpose as the ones on Earth, to take in waste gases and expel breathable ones. Ostensibly, Thanos was killing half of everything to save lives, but at that point, he's also basically just killed a whole bunch of people that he was trying to save.

If half of all plant life disappeared on Earth right now, it would be a disaster that would destroy life as we know it. Even with the vastly reduced carbon emissions of the halved population, the levels would still be more than could be dealt with.

7 Perfectly Halved?

So, next, let's look at the proportions of the Snap's victims. How did that work? Was it like a math problem where the Infinity Gauntlet took the entire population of the universe and divided it by two? Or was it on a planet by planet basis?

Either way, it ends in disaster. If it's just random, then some planets will still use too much in terms of resources, dooming the inhabitants and civilizations Thanos wanted to save. If it went by a "half the life on a given planet" basis, was it half of every species? That's very important because of the delicate balance that makes up a planet's biosphere.

Thanos, again, was trying to save the universe by killing half of everything to save on resources. However, living things make up the food chains of just about any biosphere that humanity can conceive of. So, killing half of the universe's available food supply is supposed to be a good thing... somehow?

Though Thanos was trying to conserve resources, impacting the food chain on any given planet so drastically could actually compound the problem in several ways, creating a staggering degree of fallout that's almost too big to begin to unpack.

5 Dust To Dust

So, the Snap killed living things by reducing them to dust. That's a lot of dust. It all comes down to the Conservation of Mass Theorem and the fact that the movie Gauntlet doesn't make Thanos a god, so he can't break the rules.

So, why is all of the dust a problem? Well, it has to go somewhere. If half of everything on Earth died and was all reduced to dust, that dust would go up in the atmosphere, blocking the sunlight and possibly causing a nuclear winter type situation in more densely populated areas, killing people and destroying resources that the Snap was meant to save.

4 How Did He Know It Would Work?

So, after Thanos snapped, a few things happened. Half of everything died, he burned himself, and the Gauntlet was pretty much left inert, drained of most of its power. Now, with the Power Stone, it was known that it hurt people who used it, so it stands to reason that all of them together would hurt him worse.

So, how did he know it wouldn't kill him even after putting them all together? For that matter, how did he know it would even work? Actually, how did he know it actually worked? The movie Gauntlet didn't grant godhood. The whole thing was a huge risk that a "master" strategist like Thanos shouldn't have taken.

3 Maybe Do Some Targeting?

So, Thanos was fought by the Avengers and Guardians of the Galaxy as he was getting the Stones. He knew that they would be a problem for years. However, he left a fair number of them alive, including some of the most dangerous ones, such as Captain America, Captain Marvel, Thor, and Iron Man.

At this point, wouldn't it have made sense to make sure that when the Gauntlet did its thing that it would take more of them with it? If he can be as specific as "half" of all life in the universe, surely he could have made sure the do-gooders were on the dusty side of the line? Just in case they figured out a way to undo it at some point, of course.

2 His Reasons, Part 1- The Comics

In the comics, Thanos was in love with the physical embodiment of death, Mistress Death. He had offered to kill half the universe for her and that's what he did. She, however, rebuffed his advances completely.

So, Thanos was virtually a god at this point. He could do anything he wanted. That includes seeing the future with the Time Gem. So, why didn't he know that she would reject him? That's not to say he wouldn't still do it, but it may have saved him a little heartbreak after going to so much trouble planning his genocidal date night.

1 His Reasons, Part 2- The Movies

Basically, if he was killing half of everything to save the other half, he actually screwed over the remaining half worse than they would have been if he had done nothing.

Biospheres are all about balance, as we've pointed out above, and Thanos would have thrown them completely out of wack with his actions, causing multiple species to go extinct. The movies were trying to make more sense than the comics, but failed completely in that sense, leaving Thanos with an even more confusing set of ambitions than before.
