Hello,
I have registered here in the hope that someone can answer a couple of dumb questions! My 6 year old son is very interested in planets etc and i cannot answer some of his questions. If anyone is inclined to help me out I'd be so grateful.
1) How do we know that there are millions of galaxies when we cannot see or travel that far?
2) How can we estimate how many stars exsist in unexplored galaxies?
3) Suppose the big bang started with a single particle, where did that particle come from?
4) Something cannot just appear out of nothing, right? So where did the gases and space dust come from in the first place?
See just an old dummy here who needs a friendly scientist to help her out!
Thank you
