Well, I understand he's not saying the universe is actually 'creating itself' in any sense, its slightly absurd to say the universe is creating itself, because it would have to exist before it existed to create itself, it sounded like sloppy wording to me.
It's just another way of saying physics is different at Planck scale and prior.
Quote:The other interpretation of our results, which is favored by most scientists, is that it indicates that the General Theory of Relativity breaks down in the very strong gravitational fields in the early universe. It has to be replaced by a more complete theory. One would expect this anyway, because General Relativity does not take account of the small scale structure of matter, which is governed by quantum theory. This does not matter normally, because the scale of the universe is enormous compared to the microscopic scales of quantum theory. But when the universe is the Planck size, a billion trillion trillionth of a centimeter, the two scales are the same, and quantum theory has to be taken into account.
