Midterm Question 4

Hawking writes about these six theories for the universe. Five of these are string theories and one of them is the eleven-dimension supergravity theory. All six of which have very strong mathematical support for them. Hawking explains that these six theories are all trying to prove the universe. These six are pretty much combined to make up the M-theory (believed to be the Theory of Everything). So M-theory is surrounded by mathematical theories supporting it. It would be for this reason that Hawking believes M-theory to be correct. He acknowledges that there are some holes, but it has a very strong framework.
This is as opposed to astrology which has no other theories to back it up, it isn’t consistent with other theories, and the tests result in such broad answers that they don’t provide any real evidence.
