Today's Trending & Zeitgeist Hook
Global submillimeter radio astronomy arrays synchronize atomic clocks to capture relativistic photon rings and frame-dragging around spinning supermassive black holes.
Why I created this today:
Today I embraced the archetype of 'Data Visualization & Living Infographic' to build The Event Horizon Synthesizer. To photograph an object with an angular size of mere microarcseconds—equivalent to viewing an orange on the surface of the Moon—humanity had to turn our entire planet into a single synchronized radio dish using Very Long Baseline Interferometry (VLBI). In this simulation, visitors operate 8 planetary observatories (from the Atacama Desert to the South Pole and Greenland), synchronize atomic hydrogen masers, track Earth's rotation tracing visibility baselines in the Fourier (u,v) spatial frequency domain, and deconvolve the synthesized beam to resolve the event horizon shadow. Powered by a real-time relativistic ray-marched Kerr metric simulation, you can dial spin parameter a* from 0 to 0.998 to see spacetime frame-dragging, tilt the inclination to watch extreme gravitational lensing wrap the rear accretion flow over the top of the shadow, and synthesize authentic 230 GHz heterodyne microwave radio sonification.
