This theory is not just by Stephen Hawking. A lot of people are working on
it and the original concept of strings or supersymmetry was not invented
by mr Hawking. (our own mr. Dijkgraaf has put a lot of work in this too,

Not exactly. He says that space-time is something like a hyper-ball. It
has no beginning or end, but it is finite. It does not involve even higher
dimensions.
