I made a black hole exploration game based on Schwarzschild physics and research on what happens beyond the inner horizon
You wake up alone on a research station orbiting a black hole. Your task is to measure it, build a descent capsule from the station's remaining materials, and find out how far you can go.
The exploration isn't just about falling in. You have to plan your trajectory, navigate around radiation and thermal anomalies, monitor the capsule's condition, and study what happens as you approach and eventually cross the event horizon. Capsule design matters too — hull materials, shielding and engines all involve trade-offs.
For the visuals, I use a closed-form approximation of exact Schwarzschild light deflection. Each pixel's view direction is bent before a single cubemap lookup, rather than using ray marching. This lets me render gravitational lensing at roughly skybox cost.
One important distinction: the physics-based simulation has its limits. Beyond the Cauchy horizon, the game moves into a speculative interpretation informed by published research on mass inflation. I'm not presenting that part as established physics.
The game is called Event Horizon Research, releasing November 4:

I'd be especially interested in hearing what people here think about the approach to black hole physics and where I've drawn the line between simulation and speculation.
Disclosure: Generative AI was used for some visual assets, audio and parts of the code, all reviewed by hand. The physics model and game design are my own work, developed from published astrophysics research. The same disclosure is on the Steam page.
