I cant seem to understand how we can look to the edges of our universe and see things that happened billions of years ago. I understand that the universe is expanding at an increasing rate, and that nothing can travel faster than light. If everything is expanding away from a fixed point, wouldnt we (our galaxy) have to be traveling as fast as light to be able to look back toward that point and see what happened? In other words, wouldnt the light traveling from the beginning of our universe have already passed us? Any response will help. Thanks
