I guess you are right, "The physics does not depend on what words I use". Thanks.

Thanks for the contributions. Although I further discussed this with some friends at school and we settled for this; Since there isn't any heat flow in or out from the universe, matter is not in anyway transferred out or into the universe, and work is not in any way done on the universe, why...

I agree with you on that, i also personally don't think there is anything out there besides our universe. So do you think it can be treated as an isolated system?

I have gone through some works relating to this topic and have found out that some people are still skeptical about the universe being thermodynamically isolated or closed. The universe being a closed system was based on the fact that, it could allow energy exchange between other universes in...

Can the universe be treated as a thermodynamic isolated system? And why?

Let us take this as an experiment to measure the particle at position X at zero time. If the time T of the particle is zero, then the velocity of the particle should be at infinity, which in real sense is impossible. Plugging this information into the uncertainty principle, the more accurate we...

Good point, noted..

Hmmm.. The cosmological principle and homogeneity of space holds for the universe on a large scale.. But fails when it comes to smaller distances, like the distance between the Earth and other planets, the milky way and Andromeda. On a small scale as stated in your question, the goal post does...
