Gravity

[quislibet]

Albert Einstein, who formulated basic theories about space, time and relativity, had assumed that gravity moved with the speed of light, about 186,000 miles (300,000 kilometers) per second, "but until now, no one had measured it," said Kopeikin.

That's just stupid. Turn on a flashlight and drop a spoon or something at the same time and see whether the light or the spoon hits the ground first.

Fools.

I will show them all.

please someone, explain the _speed_ of gravity to me in some sort of visual way (cnn didn't do it for me). cause all i can think of is the _force_ of gravity which must not be the same thing. i didn't realise gravity had speed.

because, if light is both a wave and a particle, then if what my wee brain understands of gravity (force/speed being the same concept), no light would leave the earth. gravity and the speed of light would cancel each other out.

this makes my brain hurt.

Um. Gravity moves?

This makes my brain all owie.

Okay. Gravity is presumed to be emitted the same way that electromagnetic radiation (light, etc.) is, through elementary particles (which don't always behave like particles, but never mind). With light, it's photons. With gravity, it's gravitrons. Therefore, as a particle, it must have a speed.

Make sense?

Want something else to hurt your brain?

If you can generate enough particles of gravity in the opposite direction that they are travelling with respect to your attraction to the earth, you can FLY.

Now, you are all totally making this up.

"First, let's postulate gravitrons! And if there are gravitrons, they must have a speed!"

Balderdash. Next you'll be telling me that the Earth is slightly flattened on one side.
