i have a question. if the a mass bends space so that it produce gravity then why those planet, like earth, does not move roll into the sun until it collides?
We would indeed if we were heading straight towards the sun. Problem is that we're rotating around it, we did from the start and we still do because of the gravity. The sun always pulls us towards it, but the gravity is simply too weak to pull us all the way into the sun. The law of centripetal force says the closer you get, the more force is needed to pull you closer (assuming we rotate). So where we are now is as close as we get.
