Gravity waves travel at the speed of light, they are similar to photons (they are quatized)


[/ QUOTE ]

I thought gravity waves were still theoretical. Something we have yet to find physical evidence for. In fact, I thought it was one of the missing links for a unified theory.

Well, no, we haven't observed them directly. But the only theories that explain the orbits of observed pairs of massive objects orbiting each other (black holes and neutron stars) are the theories that have gravitons in them.

The point is no one's saying those theories are very strong. They're just some good ideas that sound right. In the next 50 years we could easily come up with and provide evidence that supports an entirely different theory.

Maybe, but I think that different theory will still have gravitons in there some where

Or at least photons, It would seem impossible for a theory to be correct if it didn't account for light some how
