Event Horizon Telescope Caught Same Photon Across Earth to Image Black Hole
Joe Rogan Experience
#2506 - Michelle Thaller
"They had to catch that same wavefront, the same one. If it was one wavefront later, one millionth of a meter later traveling at the speed of light, they wouldn't have gotten the image."
Thaller explained the astonishing precision required for the Event Horizon Telescope's 2019 black hole image: eight observatories worldwide had to capture the identical light wave traveling at light speed, coordinated to within one-millionth of a meter. One telescope at the South Pole had to physically mail hard drives because internet bandwidth was insufficient for the data volume.
