does gravity have a frequency and if so what is it?

Question

In theory, if gravity waves have a frenquency , can they be canceled by vibrations at a sine wave opposite that of gravity.

Answer 1

Gravity waves have a frequency. That's a good point about destructive interference. I hadn't thought about that. However, from what I understand, there should be gravity waves generated by two co-orbiting large bodies. If you think about it, their gravity would increase and decrease if that was the case, but always remain far above zero. So....if you could cancel it with a gravity wave generated by another source that was identical and just out-of-phase, you should still have a baseline gravity that was nonzero.
In other words, no negative gravity (that I know of) so when it cancels, it's not zero.

Answer 2

Gravity waves have frequencies (for most sources the radiaiton is low energy and hence low frequency).

Gravity waves are more complex than sine waves. The lowest order radiation is quadrupole, so it's not a simple plane wave. Imagine that a gravity wave is approaching you along a z axis line from a distant source. As it approaches you you'll "see" distances alternately stretched and compressed along the x and y axes in the plane normal to the direction of travel.

Answer 3

Interesting thought, and if you could find that frequency and negate it at will what a handy thing. I got a feeling thats still a few years down the road though.
