Eh? What about the law of conservation of momentum? How can you exert a force on a spy satellite and ignore Newton's Third Law?

I don't know about that. It was stated that the character's didn't have to worry about meddling with the timeline because they were actually in an alternate universe -- but the reason the whole thing got started was they noticed, in the present, effects of someone traveling to the past!
Timeline was entertaining, but when you get to the end, you notice several major plot holes and become dissatisfied.

I'm impressed -- Hemos makes a post titled "I'm an idiot" and immediately gets moderated up to "Insightful".

I was under the impression that this was still a conjecture. I certainly could be wrong.

It's offtopic, but I got a laugh out of the fact that a post about someone being burned at the stake was marked "Flamebait." --Sam L-L
