About a year ago I saw an article on the net by someone who said that something infact did travel faster than light, and I posted a paraphrasing of his explanation here in the blogs.

I just found out the guy was wrong.

He stated that gravity is instantaneous and therefore faster than light. So if the sun blew up right now, we would still see the light for about 8 and half minutes, but that the grip of the sun holding us in orbit would be instantaneously gone and the earth would hurdle through space in s straight line.

It turns out that it's not the way gravity works, even though it seems logical that it would. Since Einstein had proven that nothing can go faster than light, but Newton  said that gravity would, made Einstein think about how to prove him wrong, which took him 10 years in the doing. That's when Einstein's general theory of relativity was introduced.

And I thought I had a good understanding of that theory. It turns out that if the sun blew up, that disturbance would ripple the well thats created in the fabric of space and time and travel across the 93 million mile expanse at the same rate of the speed of light, thus disproving the guys theory that I read.

A better explanation is in this video.
