Why can't we feel gravity waves?

Homework Answers

Answer #1

the way we perceive the consequences of gravity on Earth is a sensation of the ground "pushing" upwards on our feet, and preventing us from freefall towards the center of the planet.

However the gravity is basically curvature in spacetime. When you're in freefall, you simply follow a geodesic through the curved spacetime in your vicinity. In this sense, you can't "feel" gravity because there's nothing to be "felt" -- in the absence of other forces, your body is simply following a geodesic that is curved by the presence of a massive body (the earth).

If we go to moon where gravitational force is 1/6th time of earth, we will feel the gravitational force because our body is habitual of 9.8m/ss value of g... but after spending some more time at moon our body will be habitual of g/6. After that coming on earth again makes us feel of earth's gravitational force.

For wavelengths longer than about a meter the dispersion relation for gravity waves (waves for which the restoring force is gravity)is approximately given by : ω = k g Tanh(k d) where g is the gravitational acceleration, and d is the fluid depth, and you know what k and ω are.
