Lorentz transformations replace Galilean transformations when relative speeds become comparable to light speed.

Particle lifetimes increase at high speed, accelerator measurements obey relativistic energy-momentum relations, atomic clocks on aircraft and satellites show predicted timing shifts, and astronomical jets display relativistic beaming and apparent superluminal motion without transmitting information faster than light.
