Also, to curb the degenerative effects of microgravity, has NASA considered transport ships that create artificial gravity using centripetal forces from a rotating station like the one from the film, The Martian or Interstellar?

Has this study been able to help develop or contribute to personalized medicine for the masses?

First of all, I feel like I must congratulate the LISA Pathfinder team for developing such a clever experiment and for the precision with which this first mission was executed. A relative acceleration lower than 1 part in ten millionths of a billionth of Earth's gravity is simply unimaginable.

So my question is concerning the nature of gravity. Simply asked, what is it? As a third year mech. engineering undergraduate, I've learned much about it from Kepler's to Newton's Laws concerning gravity all the way to Einstein's theory of relativity. But what is the true nature of gravity? Is it a particle? Is space-time an actual physical "fabric" that permeates all of space? Is it truly a fundamental force or simply just the phenomenon of light and matter following the curve of space-item? The idea of gravitational waves alone leads me to assume that it must be some physical fabric or field that permeates spaces but I'm unsure.

So what is the true nature of gravity?

Thanks and good luck to the LISA Pathfinder team!
