Explore how stronger gravity changes the speed and shape of nearby orbits.
Dark sphere: horizon · amber ring: photon orbit (1.5 rₛ) · blue ring: innermost stable orbit (3 rₛ). Probe hidden in the unstable region.
This browser-based 3d simulation helps you explore how stronger gravity changes the speed and shape of nearby orbits. Designed for Grades 7–12, it turns an abstract idea into a model you can control, measure, reset, and test without signing up.
Explore Gravity, orbital speed, event horizon, accretion by changing the available controls and comparing the model’s visual and numerical evidence. Try one variable at a time, then combine changes to test a stronger explanation.
A typical investigation takes 8–15 min. Use it as a lesson demonstration, a guided inquiry activity, a homework experiment, or a quick review. The simulation runs in a modern web browser and does not require an account.
Explore how stronger gravity changes the speed and shape of nearby orbits. The main ideas are Gravity, orbital speed, event horizon, accretion.
Yes. You can run the simulation online for free without creating an account.
Most learners can complete one investigation in 8–15 min. You can repeat it to compare more variables or improve your explanation.
