Press "Bigger!" to travel from a tiny asteroid to the biggest star we know. The ball on screen shows how much bigger each thing is than the one before it!
Stars are born, live for billions of years, and then... something amazing happens! Press "Next" to watch a star grow up.
Drag and release anywhere in the box to launch a star! Can you make a star orbit around the black hole without getting eaten? Slower throws fall in... faster sideways throws orbit! 🌀
A real black hole has SO much gravity that not even light can escape! The edge is called the event horizon — the point of no return.
Gravity is different on every planet! Type your weight on Earth and see what happens.
