1️⃣ What is a Black Hole?
A region of spacetime where gravity is so strong that nothing, not even light, can escape.
Calibrating cosmic instruments…
Click the glowing parts of the black hole to open popups. Use the cards to focus the camera and learn in student‑friendly language.
A region of spacetime where gravity is so strong that nothing, not even light, can escape.
Many form when massive stars collapse at the end of their lives, compressing mass into an ultra‑dense point.
Crossing this boundary means no signals can return; physics as we know it reaches its limits.
From gravitational waves to the first black hole image, new data reshapes our view of the cosmos every year.
Move your cursor over the glowing regions in the scene to reveal labels like Event Horizon, Accretion Disk, Photon Sphere, and more.
Follow a star’s final journey, from peaceful orbit to a catastrophic collapse that warps spacetime.
A vast cosmic web of galaxies, dark matter, and energy. On the largest scales, everything looks smooth and uniform.
Islands of stars orbiting supermassive black holes. Our home, the Milky Way, is just one of hundreds of billions.
A massive star runs out of fuel, its core no longer able to counteract gravity’s inward pull.
The outer layers explode in a brilliant flash, briefly outshining entire galaxies and forging heavy elements.
The stellar core collapses into an ultra‑dense object. If massive enough, a black hole is born.
A point of no return. Time slows for an outside observer as matter appears to freeze at the edge.
Deep inside, known physics breaks down. New theories of quantum gravity are needed to describe this realm.
Ask student‑friendly questions about black holes, stars, galaxies, gravity, and space exploration.
Learn gravity and orbit motion by playing. The closer you get to the black hole, the stronger the pull (watch the gravity meter).
