Hi, new and pondering with much ignorance. Hence the question marks. Had to register! Are we traveling, is our planet, solar system moving along with the universe expansion? This question, statement, is prefaced on the theory that the universe is speeding up rather than slowing down. I understand we have measurements of distance and time by looking at the light spectrum upon supernova explosions that have reached us? Calculating billions of years in some cases. Which has given us dark energy because the math didn't quite add up? If the universe were created with a bang I'd assume everything in it is not necessarily traveling in the same direction? If a Sun were traveling in an opposite direction from us due to the Bang theory, would the math/distance be skewed in some way? I'm trying to get my head around this. Measuring light and to derive distance from two stand still sources makes sense in my skull but when the objects are traveling away from one another at undetermined speed(btw do we know how fast we are hurling outwards through empty space and is everything in it traveling at the same speed? Direction? Are we moving?)it becomes difficult to imagine. I think I painted a simple enough picture. So, is it fair to think of our Universe expansion being due to the one initial bang theory in a 3-D direction? And if so, is the math to determine the distance and time of the supernova explosion accurate if our planet, solar system is traveling along with this expansion? Are the stars light we see from billion of years ago possibly traveling away from us? Thanks for bearing with me and any replies.
