hello,
I was reading a recent article about gravitational waves and I had a few questions... I actually have a lot of questions, but I digress. Let me first start with what I think I know to be right, and then move on to the questions about the subject.
-Time and space are connected. This connection is represented by a fabric in which the universe is contained.
Mass is believed to interact with this fabric. What we call gravity is the result of mass and space-time interacting.. I've seen the taut sheet and bowling ball demonstration.
Is it more accurate to view space-time as a 2-dimensional plane, or to see it as a 3-D field in which things reside in?
The article I read also talked about how gravity waves traveled at the speed of light. I was wondering why this would be true? Why would space-time ripple? Water ripples when a stone hit it, and a sheet will ripple when you move the bowling ball, but how do we know that space-time has this property as well?
Thanks!
Josh
