Speed of Gravity
So, as I was reading a little about dark energy on Wikipedia, a thought came to mind. How fast is gravity? I mean, if there is something that changes mass, how quickly does that change of mass lead to a change of attraction on an object far away from it? Turns out, gravity is the same speed as light! Pretty cool.
