Thanks Bill
Why are gravitational waves only predicted for large things like rotating star and black hole systems? Why can't we see gravitational waves from smaller things like atoms or protons? Wouldn't a vibrating proton create a gravitational wave as well?

By "springyness" I mean to ask if space can behave like a spring. For example, imagine a volume of pure space with no matter in it. The space is of the same density everywhere. Now, let's squeeze a small volume of space such that it is more dense and the area around it is...
Is there springyness in space? If there is mass, and the mass is suddenly moved away, does the space quickly move back to it's original state or does it take some finite time?
I'm thinking that there is not yet an answer to this question because a springyness would show itself as waves in the...
