Just a thought I had, Seeing as a sub light speed particle cant accelerate to C, for given reasons, would this work in reverse? Would a faster then light particle (Techyons) be able to decelerate to C?

The only other thing is, to my understanding Techyons started moving faster the C (when 'created') so say this is at the Big Bang. The universe is expanding at C, right? So wouldnt all the techyons be traveling faster the the universe is expanding, thus putting them outside the universe?

tachyons could deccelerate, light has been slowed to mere meters per second. The Universe is expanding, but noone knows at what exact speed. As far as them being outside the universe, there are plenty of theories out about the structure of the uni/multiverse/whateververse.

When your talking outside of the universe, yeah your talking pure theroy. But that was simply a thought I had.

But I'm not sure 'bout slowing light particles. And even if it is possible, have you got an resouces on how the did it?

the speed of light in a vacuum is always c. The speed of light in a medium depends on the medium. ie light moving through water is slower than light moving through space.

Good point, 'difraction'. Opps, forgot 'bout that.

(Or is it defraction?)

It is commenly accepted that at least in it's early stages the universe expanded at several times the speed of light. The universe isn't matter, so is not confined to the limits of matter.
