Why is there scientific belief that gravity has speed and has some sort of substance? [ gravitron - higgs ]

Is there any evidence to suggest that gravity is restricted by d/t ?

care to discuss?

if an event occurs, information about that event cannot move through space faster than the speed of light. an object one light year away from that event cannot find out about it until one year passes.

General Relativity?

Keep an eye on this site for event observations of gravitational waves, perhaps by late 2007.

Hello all
Here is another way to test for gravitational waves http://hermes.aei.mpg.de/lrr/2006/1/article.xhtml
