Gravitational Time Dilation Using Gravity

Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events as measured by observers situated at varying distances from a gravitating mass. The higher the gravitational potential (the farther the clock is from the source of gravitation), the faster time passes.

The time seen by a stationary observer equals the time in rest frame divided by the square root of 1 minus twice the ratio of the gravitational acceleration times the radius from the center of the massive object to the speed of light squared.

Formula

QuantityVariable["t", "Time"] == QuantityVariable[Subscript["t", "0"], "Time"]/Sqrt[1 + Quantity[-2, "SpeedOfLight"^(-2)]*QuantityVariable["g", "GravitationalAcceleration"]*QuantityVariable["r", "Radius"]]

symbol description physical quantity
t time seen by stationary observer "Time"
g gravitational acceleration "GravitationalAcceleration"
r radius "Radius"
t0 time in rest frame "Time"
