Shu's theory is already taking a beating for, among other things, failing to account for the cosmic background radiation - that 3 degrees K microwave noise that's regarded as one of the chief pieces of evidence for the Big Bang. From what I've gathered ( just heard about his idea a couple of days ago myself), if he's right, then it shouldn't be there - but it is.
Doesn't mean he's completely wrong...but he gots lots of 'splanin' to do.
personal fave theory at the moment: M-brane.
