Astronomers Catch Mysterious Radio Blast From the Distant Universe

[Bear44]

Light has two speeds. The "phase velocity" describes how fast waves of a given wavelength move, and the "group velocity" describes how fast the light conveys energy or information. Only the group velocity must stay below the speed of light in a vacuum.

No matter how hard they have tried, they have never been able to find anything that moves faster than light and there are all kinds of mathematics that back that up. They have not even been able to create math that allows faster than light speed in theoretical physics. Einstein's original observations still hold true. Slowing down a photon is one thing. Making it go faster than it's max is an entirely different story.

Man...If we ever achieve light speed travel, no traffic cam will ever catch my license plate again. How cool would that be?

And we wouldn't be able to watch those high speed car chases on T.V. anymore hiss, boo....

The NASCAR crashes would be F'in awesome though.

Would NOT want to be on a pit crew.

Never mind. Bear has already posted it on another thread.
