Nothing (General)
I looked at the George Ellis article, though I had to register with the Institute of Physics to read it.-His opinion is: "The author is thus committing a category error in trying to use scientific proof in areas where it simply does not apply."-This idea that there is a realm of knowledge that is based on other methods than those of reason is the usual religious nonsense. There is no such place. Either that or he has a very restricted view of what counts as science.
