Deliverance

(I ask this in politics because R&S is not my hangout.)

Is the expansion only working at the macro level, or also at the micro level?

I may be uninformed (I don't watch TV except during football season,) but all I hear is people railing against it. If it's so bad how did it get pushed through?

At least a billion people claim that to be true. However, which is more likely... the laws of nature were suspended, or that a bronze age, knocked-up, Jewish girl told a fib? I'm not a biologist. Is there a non-metaphysical answer to this?

With no questions, Y/A ceases to exist!!!

Iron is a single element whereas bronze is an alloy of copper and tin. Why would ancient people know how to combine copper and tin while ignoring iron for many centuries? Why did it take so long for the iron age to come along? It makes me mad that the pyramids could have been built of stainless steel, while bronze is only good for making statues.

I've read that the observable universe is 93 billion light years in diameter, yet the big bang theory puts the age of the universe at 13.7 billion years. How can the size be 93 billion light years in diameter if nothing can go faster than the speed of light? How can we know anything exists past 13.7 billion light years if we can't see the light? How can there be a diameter if there is no center of the universe and everything is moving away when viewed from any point in the universe, as I have read? It all seems counter-intuitive. I realize there's probably not a simple answer to this.

What explanation is there for why the Andromeda galaxy is headed for collision with the Milky Way? Apparently, the universe is not expanding universally. It seems counter-intuitive with the big bang in that everything should be moving away from a central point.
