I don't know anything about this at all. But I often think about it! I read something once that led me to believe there is no dark matter here on Earth. But I know nothing about this so don't take my word for it. My question has been, if the universe is expanding, am I expanding? Is Earth expanding? Surely it would have to be, (?!) because I keep getting told that the universe isn't expanding into anything but rather, space itself is expanding. Well, I am part of space itself, so am I expanding? Ever so slightly? I think I read that no, in fact, I am not expanding. The space that I occupy is also not expanding. In fact, no space anywhere near us is expanding. The expansion (we think?!) happens due to dark matter (?) which is not evenly distrubuted and which we can kind of measure (?) and we can know that there isn't any here (?) Maybe someone who knows more about this can fill in the question marks or otherwise correct me.
