User Reviews

BlackHolesHD offers a visually striking, realistic-feeling look at gravitational lensing with interactive rotation and a galaxy backdrop. Users appreciate the convincing lensing effect, viewing angle adjustments, and immersive visuals. However, it is largely watch-only, with no zoom/scale or planet-adding features, and occasional rendering glitches and limited educational content. Overall, strong visuals clash with limited interactivity and features.

Pros

Convincing modeling of gravitational lensing with a ring-like appearance similar to Interstellar.
Interactive viewing controls (drag to rotate and adjust viewing angle).
Visually appealing visuals, including a galaxy background.
Feels realistic and immersive.

Cons

No zoom or scaling; cannot zoom to view lensing across more of the screen.
Mostly a watch-only experience with limited interactivity.
Rendering glitches: stray lines and rotation jitter.
No ability to add planets; missing feature many want.
Lacks educational explanations of the physics.

just add planets that’s all i’m asking for

Since this is a free tech demo, once cannot expect it to be packed with numerous features, so I’m simply reviewing it on what it is… The app does a fairly good job at simulating the gravitational lensing effect of a blackhole, by letting the user drag to rotate. That said, the effect is fairly glitchy, often having stray lines that break the fluidity effect. It’s also not possible to rotate the simulation beyond the poles of the blackhole, leading to jittery rotational glitching. The rotation of the accretion disk looks good, but it doesn’t account for the gravitation effects on the brightness of the glowing differing by the direction of rotation. It would also be nice to allow the user to scale the blackhole to see the lensing effect across more of the screen.
