Special Relativistic Time Dilation

A moving clock runs slower as observed from a stationary frame.

Formula

t = t0 / sqrt(1 - v^2/c^2) = gamma * t0

*t0* = proper time (time measured by the moving clock)

*v* = relative velocity

*c* = speed of light (2.998 x 10^8 m/s)

*gamma* = Lorentz factor

At 90% of c, time passes about 2.3 times slower for the moving observer.
