First of all this is my first post on this forum, or any other forum of this type. I am extremely interested in cosmology, physics etc. on a personal knowledge level. I usually just read stuff on the web, but Im glad to have found a place where people actually actively talk about this. I wanted to ask a few questions I just recently came up with while reading random posts. How fast are we actually moving? I guess relative to the earth we aren't moving at all, but we are orbiting around the sun. How fast do we move on our orbit? Is our sun orbiting around something larger? if so do we orbit faster in one direction than the other? is that thing(if it exists) orbiting around something larger(is it possible that our entire galaxy is orbiting around something more massive and that thing is orbiting around something more massive etc)? Is there any way to actually stop moving completely? is anything NOT orbiting around something larger? if the entire universe was only composed of 2 atoms at opposite ends of the universe, would their gravitational pull effect eachother? if not replace one atom with a SMBH, then? I guess i'll see if anyone will answer those before I go on to other stuff.
