Relativity of Simultaneity

Δ t^{'} = γ (Δ t - \frac{v Δ x}{c ^{2}})

Events that are simultaneous in one frame may not be simultaneous in another. Two events separated in space will have different time separations in different reference frames.

Variables

\Delta t'

Time interval in moving frame

\Delta t

Time interval in rest frame

\Delta x

Spatial separation in rest frame

\gamma

Lorentz factor

unitless

Relative velocity

m/s

Speed of light

m/s

Derivation

Part of the Lorentz transformation for time coordinates.
