faster than light

[Polynomial]

You are also forgetting the particle and wave nature of light.  Light can be explained both ways so with the doubling of the speed who knows how light would act.

What is your definiton of 'data', if not information? My dictionary has only that one. What is this 'data' you speak of, which needs no medium to travel?

Photons are light particles, which of course travel at light speed. Photons (light particles) ARE the medium, by which information can travel, as is used in 'fibre-optic cable'

Radio waves and microwaves will travel in a vaccuum. They have used radio waves to communicate with Space craft since their inception.

Photons are radiation, light is included in that.

My main (and only) point was with seeing light.  If you had a, say... F-18 at the speed of light and your navigator shined a light behind, could you see it?  To answer this question, I would most trust facts from the speed of sound.  When Chuck Yeager was bopping around and passed Mach 1, could he hear his engine behind him?

Hyvry,

I think we best leave things as they are. We don't seem to be on the same wavelength (pun intended ).

I have read (many times) Einstein's theory of Relativity, those concerning parrallel Universes and a few of his more obscure ideas, and am, I feel, as familiar as a Layperson can be.

Thanks guys. You gave me a headache from thinking. . .

Who ever heard of  a time machine with headlights anyway? Not H.G., I reckon!  ::)

I promised to keep out of this but I've been following it closely along with the one on time travel. All I cay say is that you lot have rich imaginations.
