If the dinosaurs were killed off in a mass extinction, then how can they simultaneously be the precursors of chickens and other birds? Isn't this sort of an either/or thing? Either they all died off/or they didn't, but rather evolved into modern avians. Or are we saying most died off, but the ones who survived, evolved into that McChicken sandwich? And if the latter, then which died off and which survived to give me chicken nuggets? I would like some clarification here, please. Is T Rex dead or just nibbling corn awaiting his tasty, tasty doom?
The size of the universe. OK, seriously, this makes my head hurt. 1) The universe exploded from an infinitely-small point 13.7B years ago (more or less). 2) The universe is infinite. 3) No object can travel faster than the speed of light. How do you square this circle? If nothing can travel faster than the speed of light, then no object can currently be more than 13.7B light years from the ultimate 'ground zero', ergo the universe must be finite since nothing in the universe can be further away from that defined point than 13.7B light years. Q.E.D. EXCEPT THEY KEEP TELLING ME IT'S NOT FINITE! Ouch. Seriously, someone explain this.
