I would imagine it solves the horizon problem and does away with the need for inflation in the early universe; if he can also sort our dark matter and dark energy he's doing rather well, all he needs after that is an "acid test" that will distinguish his theory from GR (much as the 1919 eclipse was supposed to have been the acid test for GR vs Newtonian gravity) and he can claim his Nobel (if he hasn't got one already). In fact, I'm fairly sure we have the Magueijo book somewhere. (When do I get my ansible?) > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
