This question already has an answer here:
Let me preface this by saying that I'm a high school student so my knowledge of GR might be seriously flawed.
As far as I'm concerned, Einstein's theory of GR states that matter curves the fabric of space-time so instead of there being an imaginary "tug," objects are simply falling in.
My question is, how do the objects "fall" in because in real-life simulations of the curvature of space-time, the force that's causing objects to "fall" in is Earth's gravity. In other parts of space, what causes objects to "fall" in. Does the Newtonian "tug" of gravity still exist within Einstein's theory because, without it, I can't seem to understand why curving space-time would cause stuff to "fall" in?
