relativistic effects
Near-lightspeed phenomena
Relativistic effects are phenomena that become significant when objects move at speeds approaching the speed of light, or in extremely strong gravitational fields.
At such extremes, time slows down, lengths contract, and mass effectively increases—consequences predicted by Einstein's theory of relativity.
These effects are negligible in everyday life but essential in particle physics, GPS satellite calibration, and astrophysics: At relativistic speeds, time dilation becomes measurable.
