Remember kids, time is fake
But modern technology can’t deal with flowy time like this. As a result, the timekeepers at Boulder and elsewhere make corrections to ensure these different flows of time look like they’re ticking in lockstep. The same goes for satellites farther from Earth, like those that make up the Global Positioning System. The system works by measuring the time difference between several satellites carrying clocks in space to the time that people measure on the ground.

@thatguyoverthere I just picked up Katie Mack's book 'The end of everything' (referenced in the article) when I visited the Greenwich Observatory. For hundreds or thousands of years we needed a sense of time to know our position on the Earth. With every step to improve the measurement of time we have improved our position on the planet. From the time of the year, to midday, pendulum clocks, time accurate star maps, and through to the atomic clock. #spacetime
