According to the Big Bang space is expanding and all that we see is expanding with it correct? Also time and space are intertwined somehow (I can't as of yet grasp exactly how but I'm sure I will in the future.) which then leads me to theorize that time itself is expanding along with space.
Now if time were expanding along with space is it possible that the galaxies in the Universe coudl actually not be speeding up due to some unknown form of energy? Could it just be an optical ilusion to us as a result of the expansion of time?
