Hi,
There are two types of discussion of time travel. One is the pure BS type that is going on in this thread. Of that type, I agree that "there's no point discussing or debating such theories." In Fact, I believe I said it first.
There is a much more interesting type of discussion of time travel. That is the one where a physical theory that comes close to explaining the observable universe includes within itself the possibility of some form of time travel. A number of such theories exist and are being studied and their ramifications examined. That's how the scientific method works, a hypothesis is postulated that explains all known facts. The hypothesis gives birth to new possibilities which are tested. On the basis of the results of those tests, the hypothesis is (1) provisionally accepted, (2) rejected outright, or (3) modified and tested again.
However, the second type of discussion cannot be held on most fora simply because very few people are conversant enough with the details of the theories to say anything of real use. Most of the "speculation" is really nothing more wild guesses based on ignorance or misunderstandings of the underlying theories. Or, more often, pure moonshine.
Ah, well.
