GW150914 · · 1.3 billion light-years
A lab of real physics.
Two black holes, 36 and 29 times the Sun's mass, spiral in and merge. The sheet is spacetime: your cursor or finger dents it, and a click or tap sends a ripple.
Modules
Each module pairs real public data with the physics that explains it. Change the parameters and see what the model predicts. Press ? or H in any module for help.
- Gravitational waves
A black hole's shadow
Trace light round a spinning black hole: the shadow, the photon ring and the bent disk. Compare it with the EHT's real images.

Gravitational-wave chirp
Two black holes spiral in and merge. Change their masses, hear the chirp, fit them to real LIGO data and browse every detected event.
webvrarOpen module → - Quantum
Double slit
Fire photons through two slits one at a time and watch the fringes build. Switch on a which-path detector and they vanish.

Find the Higgs
278 real CMS collisions with four leptons. Move the cuts and watch a bump form near 125 GeV: the Higgs.

Dark matter in galaxies
Real rotation curves of 163 SPARC galaxies. Stars and gas alone fall short: add a dark matter halo and fit it.

Currencies and the Higgs
Countries trade currencies on a small map. Find the loop of exchange rates that pays, then sell gold and the field gets a mass: Maldacena's Higgs.

New events as observatories report them, with papers and lab news. Most alerts are preliminary until a later analysis confirms them.
