Gravity Well Simulator
Climb out of the well: An interactive journey through the geometry of gravity and orbital mechanics.
Gravity Well Visualizer
Inspired by The Expanse • Drag planets to warp spacetime
Mass B (Mars-like): 0.4 M
Real-Time Spacetime Deformation
Watch as the coordinate grid responds instantly to the presence of mass. By using a vertex-displacement algorithm, the simulator visualises gravity not as an invisible pull, but as a physical curvature of the 3D environment.
Users can see exactly how a “gravity well” creates a steep incline that objects must climb to reach deep space.
Dynamic Multi-Body Interaction
Move multiple celestial bodies—such as an Earth-like mass and a Mars-like mass—to see how their gravitational fields overlap and interfere.
This feature demonstrates the “Lagrange points” and the complex gravitational “tug-of-war” that spacecraft must navigate when traveling between planets.
Orbital Velocity & Escape Trajectories
The simulator includes a dynamic test particle to demonstrate orbital mechanics. Observe how velocity allows an object to maintain a stable orbit within the curve of the well.
Experiment with “Escape Velocity” to see exactly how much speed is required to break free from a planet’s curvature and reach the flat “high ground” of the interplanetary void.
