Hi all, I'm a beginner to physics stuff and am just learning about space time and general relativity. Often the graph above is used to show a spacetime graph, but I am confused as to what this graph actually means.
Does it represent how much time t passes every "normal" second based on a position x, y, z? But if it did, then gravity wouldn't act as a field force but rather would just multiply your velocity by 1/t (I'm probably wrong about this)? And also, if time were to "slow down" when near a gravitational force, that wouldn't affect your velocity from your own point of reference.
I know this is probably a stupid question, but what is the correct interpretation of this function/graph?
