The Best Test of General Relativity (by 2 Misplaced Satellites)

The video discusses the launch failure of Galileo Satellites 5 and 6 by the European Space Agency, which led to an unexpected opportunity to test general relativity. The satellites were launched into incorrect orbits due to a thermal issue, but scientists used this to measure gravitational effects on time. The video explains the mechanics of atomic clocks and the challenges faced in conducting these experiments. Despite confirming general relativity, the results highlight the need for further tests to explore potential deviations and improve our understanding of gravity.
