GPS only works because time is wrong

Every GPS satellite has a clock set to the wrong speed.

Because in space,
time runs differently.

Without correcting for relativity,
your location would be off by kilometers.

So engineers adjust the clocks before launch.

Every time you use GPS,
you’re relying on Einstein.
