Okay, I was wrong about the phrase "chain reaction" not appearing in the comic, but it doesn't change a thing because you completely ignore one key piece of evidence. One bomb did go off when Iron Man failed to defuse it and it did destroy one fifth of the universe! No chain reaction. Just destruction.




Apparently you did not read your own link. Thor did not cut the bomb off from the rest of space/time. He created a vortex, which while doing so Thor "shattered the laws which govern time and space." You like to talk about Superman being able to mess with space/time. Here's Thor doing it. And it is explicitly the vortex that contains the bomb's explosion. Hawkeye says, "You managed to completely contain the force of the blast!"




Half a galaxy? Pffft. That's nothing compared to Thor's one fifth of a universe, which contains billions of galaxies.
