I apologize for my ignorance but I've looked around a decent bit and still don't quite understand. I understand its no longer a force as Newton described it, but then the bowling ball on a trampoline analogy is useless without a force such as gravity to accelerate objects in the metaphorical "down" on the trampoline.
I have also herd the term geodesics thrown around a bit an I can understand that traveling along one of these lines may simulate a force, but why is it assumed that we are traveling? What's causing the traveling?
I guess the simplest way I can think of describing my confusion is envisioning a dart. If you throw a dart through curved space-time, I can understand how its path can look curved in any number of directions. But what happens if you simply hold on to the dart? Isn't it then no longer traveling through space and only time? What makes it want to travel through space when I release it?
