Ok, so my question isn’t actually about whether or not the speed of gravity is equal to that of light, however, after being given a link from BBC News about the speed of gravity being proven as equal to the speed of light I got a little confused. Now, of many things I might be I’m definately not a physics major, however for some reason the concept of measuring gravity doesn’t quite come through clearly, so, if anyone could kindly explain how one would go about measuring the speed of gravity since the article ( http://news.bbc.co.uk/1/hi/sci/tech/2639043.stm ) doesn’t clarify much about it, with the exception of saying that they measured how the gravitational field of jupiter bent radio waves emitting from a quasar
The funny thing about the SOL is it’s relative. If you are traveling at 1/2 c then the speed of light is exactly the same as it is to the person sitting on the space station at 0 c. I don’t know if gravityu has this property.
There’s already a thread in progress about this:
Gravity moves?.
