I have always believed that the objects billions of light years distant “discovered” by our most powerful telescopes probably aren’t there anymore and have been gone for billions of years. At best, objects we see are not the same now. We will never know. The universe might be smaller than experts think it is.
Interesting hypothesis. However, matter = energy. Energy is neither created nor destroyed, it is only transferred. Therefore, whatever was there billions of years ago is now something else. Shouldn't it all still be moving in the same direction though?
At least those are the laws or physics in our part of the universe.
