In no special order ...
I wonder what Earth's population would be if the wars that man has fought through the Ages never happened. Millions more? A Billion?
I wonder how scientists can contemplate a 'closed' universe. If there was a Big Bang, and there was enough matter to 'close' the Universe after that Big Bang, then Expansion never would have happened. The Universe never would have gotten bigger than a beach ball.
If (and it's not proven yet) neutrinos really do exceed the speed of light, what else does? And is this what "Dark Matter" might be - stuff that moves faster than light?
If the Universe actually rotates, is Matter favored over Anti-Matter because Matter rotates in the same direction as the Universe, and Anti-Matter's rotation is counter?
Why do we give value to form over function - as in "What a Car looks like" as opposed to "How well it works"?
I wonder what it's like to drive a Tesla?
I wonder what would have happened had I stayed in school rather than gone in the Service?
