The Time Dilation Museum

Time is not absolute — it bends with speed and gravity. From Einstein's thought experiments to the GPS in your pocket, explore how the universe keeps different clocks.

The Twin Paradox

Two clocks side by side — one stationary, one traveling at relativistic speed. Drag the velocity slider and watch time itself slow down for the traveler. The Lorentz factor γ determines exactly how much.

v = 0.50c γ = 1.155
Stationary clock: 0.00s
Traveling clock: 0.00s

A Brief History of Time Dilation

Scroll through the milestones that revealed time's true nature — from Galileo's pendulum to LIGO's gravitational waves.

Playground

Try it yourself — calculate the Lorentz factor, simulate GPS drift, or watch a cosmic ray muon cheat death.
