Ok when the big bang happened the universe was formed and began to expand outward, now here is what i'm confused about, time moves forward as the universe expands, and the universe becomes a bigger place so if a person was to travel back in time would everything be smaller because the universe was smaller at the time you travelled back to, sure going back in time 20 years probably wouldn't make a difference but what about 100 millions years ago, wouldn't sub atomic particals be smaller because the whole universe was smaller and more compact?
