I saw this this morning and was going to post but you beat me to it. I knew you would be "skeptical" lol.

Radiation probably not the correct way to look at it. Gravity is not transmitted through electromagnetic radiation. We have never been able to observe theoretical bosons called gravitons though. If they do exist, there is no experimental evidence to suggest that they propagate faster than C that I am aware of. An interesting question is how does such a particle if it does exist interact with the architecture of space and how is it generated from the interaction with the fields that impart mass?
