At Fairleigh Dickinson University in Teaneck NJ they built a gravity wave detector. They havent seen any activity in a couple of years since it was built.

It is a form of a particular kind of energy, which form of energy is apparently that of the value "h" (Plank's constant). Stephen Hawking in "A Brief History of Time," page 92, paragraph 3, states; "Like light, gravitational waves carry energy away from the objects that emit them". The manner by which these waves are formed is found as being part of the physics trilogy: E = mc2, m = E/c2, and c2 = E/m. The last is that of a field of physical time, or that of a field of gravity. Notice that as the "E" value rises and falls so, also, does that of a field of gravity. Were a mass identical to our planet to have no heat energy within its mass, then that planet would have no field of gravity connected to it. Were the heat (E) value of our planet to increase, then the field of gravity would also increase.
The waves themselves appear to be an expression of "h", the smallest energy value known. These small waves comprise electromagnetic energy of which our universe is formed. There is a short writing at http://360.yahoo.com/noddarc "Concepts Concerning Gravity, Time, and Energy" that may be of interest. Also, a few months ago an experiment was performed that demonstrated a field of gravity is able to be increased and decreased. It is found at http://youtube.com "successful gravity experiment" is its title. This last video takes a long while to go through in that it was posted in segments. The posting was done for information purpose.

supposedly, like light, gravity is transmitted by "gravitons" or "gravity waves." A few years back, two black holes merged in a far off galaxy, and it was proposed that if we had a device that could detect gravity waves, *that* event would've set it off. It's unknown what possible good it would do us to describe the 'graviton', but it would be another piece of the puzzle of our multiverse...

it is a disturbance of the fabric of space which propagates as a wave. supernova explosions create gravity waves.
