Tap the black hole's parts to learn what they are.
The only place where you can stare straight at "nothing" and watch space bend around it. Everything here is computed with real physics from Einstein's equations.
Drag with mouse or finger, or press A / D to look around.
W and S move you closer and farther. Scroll works too.
Follow the Journey. Click anything glowing. Ask questions.
Journey resumes any time — no wrong turns exist here.
Your browser couldn't start WebGL2, which this exhibit needs to compute curved spacetime. Try an up-to-date Chrome, Edge, Firefox or Safari with hardware acceleration on — then come straight back; the black hole isn't going anywhere. It literally can't.
