Balkhaev is an interactive science and visualization project focused on the experience of falling into a black hole. Its central offering is a browser-based simulation that lets visitors explore views at different distances from a non-rotating Schwarzschild black hole. Users can adjust the viewpoint and depth, examine how light bends into multiple images and rings, and observe how gravity and motion shift light toward red or blue.

The experience also illustrates delayed signals, changing views of an accretion disk, tidal effects, and the relationship between local observations and the flow of time. Explanatory panels describe the underlying physics, assumptions, and limits of the model, including its use of Schwarzschild radii and the point at which the simulation ends. Rather than assigning an unspecified black hole a mass, the project presents distances and times in relative units.

Balkhaev combines an immersive visual experience with detailed scientific context, helping users explore how a falling observer might perceive light and the surrounding universe. The site also provides contact links through Telegram and email
