Black Hole Imager
See a spinning black hole as it would really look: every pixel is a light ray traced through the Kerr spacetime, with frame dragging, Doppler and gravitational shifts, an accretion disk and your own 3D objects.
Use them right in your browser – no downloads, no installs.

Launch particles, light rays and spaceships around a spinning black hole – orbits, light bending, frame dragging and time dilation.
An interactive 2D gravity simulator: planets, binary stars, asteroid belts and colliding galaxies with real physics.
Do prime numbers hide a pattern in base 3? A live laboratory that tests the idea with exact computation, controlled statistics and the zeros behind the primes.
