Frequently Asked Questions

Is this simulation scientifically accurate?
Yes! We use a high-precision numerical integrator (Runge-Kutta 4th order) with adaptive time stepping to ensure accurate gravitational calculations while maintaining interactive performance.
Can I save and share my simulations?
Absolutely! All simulations can be saved as JSON files or shared via unique URLs. Pro and Enterprise tiers include cloud saving and collaboration features.
What devices and browsers are supported?
THREE BODY works on all modern browsers (Chrome, Firefox, Safari, Edge) and is fully responsive for desktop, tablet, and mobile devices.
