How to get around Gravity Lab, and the real science behind what you see in it.
Using Gravity Lab
Getting startedFlying, finding things, controlling time, and the two ways to see the scale of space.
Sandbox ModeSwitch on live gravity, then add, throw, grab and explode anything. Includes all 14 ready-made scenarios.
The Theory LabDesign a starship, build a warp drive or a wormhole, and see which laws of physics stand in the way.
The science
How black holes lookWhy the accretion disk wraps over the top, what the photon ring is, and how Gravity Lab ray-traces it.
When galaxies collideTidal tails, dark-matter halos and dynamical friction, and the Milky Way's merger with Andromeda.
Asteroid impactsAirbursts, craters, blast waves and global winters: what decides how bad an impact is.
What's real and what's simulatedWhere each part of the universe comes from, and how simulated objects are labelled.
