Relativistic Time Dilation

Time dilation is the phenomenon of a slowing of time as measured by an observer who is traveling at any nonzero velocity relative to the object.

The time seen by a stationary observer equals the time in rest frame times a factor that decreases as the velocity approaches the speed of light.

Formula

QuantityVariable["t", "Time"] == QuantityVariable[Subscript["t", "0"], "Time"]/Sqrt[1 + Quantity[-1, "SpeedOfLight"^(-2)]*QuantityVariable["v", "Speed"]^2]

symbol description physical quantity
t time seen by stationary observer "Time"
v velocity "Speed"
t0 time in rest frame "Time"
