Quantum mechanics has a quantum of gRavity? What is its description?

Question

Was it not Understood that quantum mechanics had no mechanism for explainning Gravitation?

Answer 1

the hypothetical boson which mediates gravity is called the graviton. the graviton travels at the speed of light.

look here:
http://en.wikipedia.org/wiki/Graviton
http://en.wikipedia.org/wiki/Gravitational_radiation

general relativity says that bodies which orbit each other will emit gravitational radiation, and single bodies which oscillate between being flattened at the poles and stretched at the poles will also emit gravitational radiation.

here is the web site of some of those looking for gravitational radiation.

Answer 2

Quatum works really well for the little things like atoms. But does not work on the bigger things like you or a planet. Gravity and Einstein reliativy works really good on big things but cant do the small stuff.

It is that the big rules dont work small and small rules dont work big that has everybody trying to figure out why.

Answer 3

It's called a graviton, and experimenters have been on its trail for decades, so far without success. We are pretty sure that it exists, however, because of the slowing down of rotating pulsars.
