it is a theory with regard to the fact that gravity travels faster than light, i have heard this to.
i do not know if it is true, but i think the scientific community are looking into the fact that we may not know everything about gravity.
The speed of gravity has been measured for the first time. The landmark experiment shows that it travels at the speed of light, meaning that Einstein's general theory of relativity has passed another test with flying colours.
Now me with my radio, i shout "look out!" and 8 years later you turn around but are already dead. Lets say instead i give that 2x4 a nice solid push (so much for inertia, but so what), youre gonna feel that 2x4 hit you in the gut right away and whiizzz, the micro-meteorite just misses.

I dont know about that... you can demonstrate unequivocally that in a material with no gaps, the shockwave travels at light speed and not instantly? Got a link?
Basically we know that an increase in the density of a medium decreases the speed of light... as density proceeds to infinity a point where "sound" travels faster than "light" should certainly occur, neg?
