Where is our universe traveling? I understand that the Earth revolves around the sun. And so does the other 7 planets. But what about the sun? I don't recall it revolving around anything. Are we just hurtling through space in one particular direction. Where are we going. Are we going further into the Galaxy? What about the entire Galaxy as a whole? Where is this HUGE Galaxy made up of trillions upon trillions of rocks heading towards?
