Went for my evening walk re-listening to an astronomy lecture “Big Bang 1” About Cosmology: that looks at the universe as a whole, cosmological principal: that assumes that the laws of physics are the same throughout the universe, and space on a large scale is both Homogenous: matter is distributed uniformly throughout the universe, and Isotropic: there’s no preferred direction in space.
Read an article the other day “Before the Big Bang; three theories explore the back-story of creation” in Discovery Magazine that Ron left me. I know the subject matter somewhat and didn’t find too much of anything that I didn’t already know. There was one about the Arrow of Time that delves into the direction of time, entropy and equilibrium, where the universe keeps expanding and get to a state of “low entropy” creating other “Big Bangs”, which I found interesting. Also there was another that states there is no such thing as time, only now. This idea of only “now” is something I wrote about before in my column: “Thought for the week: An instant in time is all we have to plan for the future and think of the past. Thought for the week: Time is an illusion."
