Just wonderng if anybody caught this rather interesting documetary on BBC2 the other night ? [URL]http://www.bbc.co.uk/science/horizon/2003/timetrip.shtml[/URL] Basically, they explored each 'viable' scientific method of time travel. In the end they came to the conclusion that the [I]simplest[/I] method of time travel could be via computers. Given the advances in computer processing power it should be possible for computers in the future to be so fast that they can calculate an INFINITE number of calculations. If this was possible they could create and entire virtual realty of the past and [I]possibly[/I] the future. Then it all became a little scary :MILD: ! They reckoned that it was more likely (based on mathematical probability) for this to have actually happend and that we are actually [I]living[/I] out a program. A bit of a cross between the Matrix and a Star Trek Holo-deck. Overall, a rather enjoyable waste of an hour.
