Matter Discovered Traveling at Near Light Speed 403
mcgrew writes to mention New Scientist is reporting that scientists have clocked matter traveling at 99.999% the speed of light. "The fastest flows of matter in the universe shoot out of dying stars at more than 99.999% the speed of light, new observations reveal. When a massive star runs out of fuel, it collapses to form a black hole or a neutron star. In the process, some of the matter from the star also explodes outward at blistering speeds, producing an intense burst of gamma rays and other radiation."

"The speed can be translated into something called a Lorentz factor, a number that describes how much time slows down for objects moving close to the speed of light.?"
Let it be clear, time does not slow down for the object. Time, if there even is such a thing, rolls along as it always rolls along for the object. It's just that for most of the rest of the universe (which is more sedentary compared to that of the object), time speeds up.

But as other guy said, yea gravity propagates at the speed of light. We can test this (with precise instruments) because you can measure the pull of the moon easily. If gravity propagated instantly the moon would be pulling from an angle that would be 1.28 seconds ahead of where the moon appeared to be.

Not to mention that there would probably have been relativistic effects making your speed (from your viewpoint) and your speed (from the cop's viewpoint) significantly different!

I hate it when Einstein is used as a muzzle for imagination and thinking outside the box. I think he would hate it too.
