What is the "speed of light technology"? I am not too sure to get what you are referring to. I won't answer most of your comment because I am not sur to get the question, but feel free to come back to me and we will continue chatting ^^
Just one thing: the golden rule is that nothing can go faster than light. We were assuming that gravitational waves were traveling at the speed of light, but this has only been confirmed a year ago when gravitational waves emitted by the merging of two neutron stars have been observed together with gamma rays originating from the same event (in short, both the gravitational waves and the light arrived to Earth at the same moment).
