I refute this, actually. Look up Project MKULTRA. That's what they let us know. Imagine what we don't. (And no, I am not a conspiracy theorist. I am going for my PhD after I graduate this summer).

I don't think an explosion can occur in space. At least not one with any flames. But momentum doesn't apply in any way to that lol

I will sum this up in 2 quick and accurate ways: 1: Space is a vacuum. There cannot be explosions in space, as there is not oxygen in space, which fire requires. The movie Armageddon also got this wrong with their nuclear bomb detonation. 2: When you complete a space mission, you go into lightspeed. Now, the issue -- while in lightspeed, you can shoot missiles. The missiles travel ahead of you. Therefor, the missiles are traveling faster than you in lightspeed, and in turn, faster than the speed of light. This is impossible.
