The Speed Of Gravity Revealed

redwolfoz writes "New Scientist is reporting that 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.' Researchers made the measurement of the fundamental physical constant with the help of the planet Jupiter. One important consequence of the result is that it will help constrain the number of possible dimensions in the Universe."

Hmmm... How could we make a weapon out of this?

Well, what if we could accelerate a missile toward the speed of light; it's mass would increase and I would assume it's gravitational field would also increase. If the projectile could approach the speed of gravity (which is probably very close, if not the same as, C) it might radiate a cone of 'compressed' gravity (similiar to a sonic boom). I imagine such a thing could make a very amusing weapon.

Just think, that tree will have 95 more rings before Sonny's copyrights expire.
