Thank you Ibix for kind reply :) You are right, using language should be more careful here. Those theories or solutions are mentioned, just because they represent typical prediction about the fate of Universe, expanding, steady, or contracting. This is a last-lasting debate, and seems no wide...

Wishing you can propose something remarkable in physics, by reading up-to-date books and posting sarcasm in forum.

Based on the fact of observed cosmological redshift, scientists have proposed different ideas to explain. One interesting question is whether gravity does negative or positive work now: According to universe expanding in Big Bang theory (Lemaitre, 1927), obviously gravity does overall negative...

Thanks for your patience, Dale. This is a serious discussion about the Philosophy of Physics. I was not trying to break any physics laws, but rather to clarify some longstanding debate problems while also protecting the laws of physics in any local frame. We all agree that the laws of nature...

When we observe distant time dilation effects, usually indicated by redshift, there are three possible explanations: 1) The speed of light, is slower there and then; 2) Space, is contracted for light there and then; 3) The frequency, of specific light is slower there and then. However, it is...
