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."
