Main Question or Discussion Point
If gravity is not a force, rather the curvature of space time influenced by a body's mass, then why do we perceive an acceleration due to gravity, as though there was a force? In my mind, it would make sense for the bend in space to only cause a massive object to change direction. I suppose if something is to maintain a constant "speed" while it is changing direction, it also is accelerating. Does this mean that when someone drops a ball and it accelerates towards earth in what appears to be a straight line, really what is happening that it is maintaining constant speed but accelerating in a different direction due to the curvature of space?
