I'm not so sure if he has seen it. I've seen the movie and I didn't think it painted him as doing it for the money. The motivations presented were mostly petty jealousy, a bit of revenge, and yes, doing it because he thought it was a cool project. I don't know the real Mark Zuckerberg, but the fictional one in the movie, while clearly a douchebag, was also a smart guy who had the motivation, energy, and guts to follow through on his idea. Not the worst light to be painted in.

I think the problem with this analogy is that you assume that you can see Ship A take evasive action immediately. For the analogy to hold up, the fastest way for you to find out that Ship A took evasive action is for someone on Ship A to attach a message to a cannonball and then fire it to you. So, on the one hand, the universe hasn't existed long enough for a cannonball fired from Ship B to reach you, the observer. Yet it has existed long enough for a cannonball from Ship B to reach Ship A, and then from Ship A to you?
