Okay, I am just fooling around with the equation Δt' = Δt * √( 1 - 2GM/RC^2) To find out the suns gravitational effects on close ojbects I keep getting a nonreal answer. I can derive the equation to this. Δt' = Δt * √( 1 - (Schwarzschilds Radius)/R) The suns Schwarzschilds radius of the sun is is 2954.14m So if I want to see how much time will change in 30 seconds from 20 meters away I do 30*√(1-2954.14/20) Then i get a non real answer. What am I doing wrong. Does this equation just have a limit from certain distances or does it just break the laws of physics if an objects time slows down from 20 meters away. If I am not doing anything wrong, could someone give me an equation that works for this stuff. Thanks in advanced.
