Ridddle · LIGO measured a change smaller than a proton

sample · UNAFFILIATED · Jessie craft demo. A 59-second science Short re-cut from Ridddle's 19-minute "What Space Really Sounds Like", built around one fact: in LIGO's first detection in 2015, its two arms changed length by only about four quintillionths of a meter, roughly 1/200th of the diameter of a proton. It opens on that number over the real 4 km detector arm, then rewinds to what caused it: two black holes spiraling together and merging, gravitational waves rippling out across spacetime, and the two L-shaped observatories in Washington and Louisiana. An interferometer diagram shows one arm stretching while the other squeezes. Then you hear the real chirp over the actual Hanford and Livingston signal plot, followed by three suns' worth of mass turning into gravitational waves, and it closes on the ripple's 1.3-billion-year trip to reach us. The narration is reordered so the payoff comes first, B-roll is re-timed to each line (merger on "merge", the sun on "sun's worth", the aerial shots on the two states), and word-synced captions run throughout. Cuts sit on measured audio minima, with a warm-high, cool-shadow grade, fine grain and -14 LUFS loudness. Not affiliated with or commissioned by Ridddle or LIGO; original footage © Ridddle.
