Sometimes I just think about big things, infinity, dark matter and dark energy. I don’t know much about them so I won’t try and lecture anyone about it. It’s just when you hear that the universe is flying apart more and more quickly and that the gravity that holds things together is not going to hold the universe together. There is something called dark matter which apparently helps hold the universe together, but there is also something called dark energy which is forcing it apart. So in the future the universe will spread out more and more till light cannot reach out and darkness will descend as the universe cools …
So that’s cheerful….
Also the idea that the universe splits each time something happens befuddles me. So if a car crashes in one universe it might not in the next. Terry Pratchett the author wrote about going down the wrong trouser leg of time. Each split can split again and again, ad infenitum.
Maybe all the dark matter and energy is the other universes effecting us? I don’t know. I like thinking about things but I don’t always understand them.
