really magnificent

Dude, there weren't any dinosaurs before the big bang. There was nothing before the big bang - no matter, no time. As there was no time before the big bang, it's not even logical to talk about "before" the big bang, as "before" is a place in time... Also, the dinosaur / meteor thing is only a theory. At best you could say "this is maybe something like what the dinosaurs might have seen assuming that a giant meteor caused their extinction. Sweet video though. Keep up the good work.
