Скачать или смотреть Why GPS Fails Without Einstein’s Time Correction

GPS feels simple: open your phone, see your location. But behind that calm blue dot is one of the strangest engineering achievements in history.

This video explores how the Global Positioning System works — and why it only functions because engineers built Einstein’s theory of relativity directly into it. Without relativistic time corrections, GPS would drift by kilometers every day.

We break down how satellites use atomic clocks, how tiny differences in signal timing turn into distance, and why location is secretly a time calculation. Then we travel back to the 1700s and the longitude crisis, where clockmaker John Harrison revolutionized navigation by teaching ships to trust time.

This is a story about physics, history, and the hidden systems that quietly hold modern civilization together — from relativity and satellite engineering to the timeless human quest to measure the world precisely.

If you’ve ever wondered how GPS works, why Einstein matters to everyday technology, or how time and navigation shaped history, this deep dive connects it all.
