I read this in Wikipedia: "EM radiation in a vacuum always travels at the speed of light, relative to the observer, regardless of the observer's velocity."

Does that mean that if I was in a car going 60 mph, the speed of light would be 670,616,629.2 mph to me? Then would it still be 670,616,629.2 mph to a stationary observer or 670,616,699.2 mph?

I wanted to know that, for example you have a sound system and it can go faster than sound. If it goes twice the speed of sound(343m/s) would you be able to hear the stereo?

It seems kind of possible. I all has to do with the mixing of your body's own kinetic and spiritual energy with that of the sun(or any other star).

I don't know a lot about physics (it may be evident) but the idea of a parallel universe fascinates me. I don't necessarily believe in it, but it's a great idea. But I was wondering, if by some chance one (or more) does exist, would it be possible for there to be intelligent life in it?

Kepler's Second Law states that the imaginary line between any planet and the sun sweeps equal areas in equal times as it orbits the sun. If the gravitation between the sun and the planets were somehow switched off and the planets no longer followed elliptical paths, would Kepler's equal area in equal time law still hold true?

a) Yes, the Second Law would still hold, even with gravity off.

b) No, Kepler's laws relate to elliptical orbits produced by gravity. Turn off gravity and Kepler's Second Law is meaningless.

I've seen films where its been suggested that we are not alone in the universe. It was said that a cover-up has been going on for years, and I was wondering what you think.
