Buller, Punch _165_ (December 19, 1923), 591) _There was a young man named Fisk Whose fencing was exceedingly brisk So fast was his action The FitzGerald contraction Reduced his rapier to a disk_ _"[6]Subluminal Applet" by Greg Egan._ There are now several experiments that show that particles and photons can travel faster than the speed of light. Whether _information_ can travel faster than the speed of light is quite another matter. Some would say that this is rigorously excluded by Einstein's theory of relativity, some say that they have shown experimentally that this is possible. A good place to start reading about FTL phenomena is the [7]FTL-FAQs page. Literature on FTL phenomena can be found on the [8]Literature on Faster-than-light experiments site. Famous people have homepages with information on the subject, for example, [9]Raymond Chiao at UC Berkeley or [10]G. Nimtz at the University of Cologne. The UK TV program Horizon once interviewed [11]some people who do research on FTL communication and time-travel. Maybe you would like to check out some FTL work done in the FRC. [12]Here is a link to a poster that was presented at a recent conference. Also check out the [13]reprint section. [14]Time-travel website. This web site is devoted to the explanation of why time travel is possible in both a forward and backward direction and just to show how serious its creators Dr S Preston and Professor K D Hammonds are, they use Dr Who's TARDIS to illustrate the pages. Dig a bit deeper though and there are some serious discussions going on, such as explanations of the nature of black holes and why they are not 'infinitely' dense at all. There's also a cheap and cheerful explanation of time travel for non-physicists in which quantum tunnelling might be used to cross over to faster than light speed and so move through time 'backwards'.
