Black Holes: A String/ Theory Perspective
Jacob Berkenstein in 1970 came up with the theory of black hole entropy. This hyperlink will better explain this theory. The main point is that because a black hole has such a high amount of entropy then the event horizon will increase. This was widely discredited because of previous thoughts that black holes were very orderly. But using string theory we can actually see the disorder of the vast amount of entropy in a large black hole. Using previous general relativity and quantum mechanics will not be able to quantify the things we are trying explain.
Reflections on Cosmology
When the universe was first burst into existence and while many things occured something to take notice of is what we call primordial nucleosynthesis. This was the period in which the universe began to cool and quarks formed into groups of three which formed protons and electrons.
Scientists will use very powerful telescopes to view the universes expansion as we have previously discussed. These telescopes not only have picked up this expansion but something called, cosmic background radiation. This led scientists to thinking that at one point the universe was exactly the same at all points and there was no places of high entropy where black holes were located. A picture of this radiation of the universe is located below.
Multiverses
The theory of there being multiple universes is one that holds that different universes hold different rules. In our universe we are in a constant outward expansion, but others may experience expansion at different times. This would then allow different universes to have different physical laws than our own.
