Hi. I have a question about the expansion of the universe. First off, I'm only 16 and I don't have much knowledge of cosmology or astrophysics other than what I've read in a few books and on this site. That said, this question may be laughed at and it may have a basic answer, but I'll ask anyway.
I've always heard that the universe was expanding, but could it be that the universe itself isn't expanding, but the galaxies and such are just moving away from each other? I always seen galaxies moving away from each other not as the universe getting bigger, just what is in it is getting further apart.
I hope this isn't a stupid question. Thanks in advance.
