I have taken physics to Modern so I understand the basics of time and distance dialation. I don't understand what is distance is. It is always given by reference to something else, or tied together like in space time. The closest I've gotten to something I can understand, and answers my question partially is http://blog.stephenwolfram.com/2015/12/what-is-spacetime-really/ Is the blog on the right path? Am I even asking the right question regarding distance? Most of what I've found looks at space time and it's behavior.
