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...
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...
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...
