🕳️ Black Hole — Gravity's Ultimate Trap

Play with a cartoon black hole! Send stars into it and watch them stretch into spaghetti.

Space Explorers3DEasy60 FPS

Approach the ultimate object in physics — a black hole! Watch light bend, time slow, and matter spiral inward as gravity becomes so strong that nothing, not even light, can escape.

🔬 What It Demonstrates

Near a black hole, Einstein's General Relativity predicts extreme spacetime curvature. Light follows curved paths (gravitational lensing), and time passes more slowly close to the black hole (gravitational time dilation).

🎮 How to Use

Drag objects toward the black hole and watch them accelerate and spiral inward. Move the viewpoint closer to see gravitational lensing bend the background stars. Adjust black hole mass with the slider.

💡 Did You Know?

The first image of a real black hole (M87*) was captured in 2019 by the Event Horizon Telescope — a planet-sized virtual radio telescope. This black hole is 6.5 billion times the mass of our Sun, located 55 million light-years away.
