Blazing Speed: The Fastest Stuff In The Universe
Unfallversicherung writes "'If you're light, it's fairly easy to travel at your own speed -- that is to say 186,282 miles per second or 299,800 kilometers per second. But if you are matter, then it's another matter altogether.' Astronomers are now measuring matter that moves at 99.9 percent of light-speed. Jupiter-sized blobs of hot gas embedded in streams of material ejected from hyperactive galaxies known as blazars."
what happens if you accelerate to 99.9% of the speed of light?
You start being able to watch early 90's tv shows. Errr wait a min, does that mean that TBS is going 99.9% of the speed of light.. humm

Two words, red shift. As a body of mass travels at relavistic speeds, the light it gives off shifts wavelegnths. Therefore, if we know what something is composed of and hence know the spectrum of light that it would produce, we can study the spectrum of light that it DOES produce and calculate the speeds that those objects would be needing to be traveling to create such a shift in the light.
