This is my 1st post here. I need help in finding an equation. I read the time moves slower for larger objects that smaller ones. For example a day form the sun’s point of view could be equal to lets say a month in earth’s view. So if I have the mass of earth and the sun’s mass how can I calculate the exact difference in time? I.e.: 1 sun day equals how many human days. I hope o asked in a clear way. I’m not asking how many times the earth rotates in 1 sun rotation. Thanks in advance
