Re: My address to the loon committii.

What do you mean by "classical"? Do you just mean non-quantum physics, or do you mean something more like "any theory of physics that's seen as reputable by the mainstream physics establishment" (ie not 'alternative physics')? Because I can promise you that all mainstream physics theories, including quantum ones, would say that light can only be bent in that way by curved spacetime, ie gravity. And as I said before, Titor seemed to claim that the principles the time machine operated on were all basically just minor elaborations on stuff that physicists already know in our time.

Tipler is actually a physicist, not an astronomer. And according to this article he didn't actually come up with this idea, he was just elaborating on an earlier paper on infinite rotating cylinders from 1937, by a physicist named WJ Van Stockum. Although the rotating cylinder would almost certainly be impossible to construct in our universe since it'd have to be infinite in length, I think it is agreed that it's a valid solution of the equations of general relativity, which means you can't really doubt the basic theory without doubting GR.

On QRXe's statements:This is allot of classical physics, which does not adhere to the topic of discussion here.

I know enough about Tipler (an astronomer by trade, not recognized for his deep grasp of difficult topics in physics) to know that his infinite rotating cylinder THEORY has a lower probability of being fact than many other competing theories from reputable physicists.
