True, the disk is rendered optically (and geometrically) thin. This is done so that real-time performance is attained on devices like phones – volumetric GR rendering would be significantly more expensive. The jet (zoom out to see it) is re

The technology has come a long way indeed! The first simulations of how a black hole would look like are from 1979, by Jean-Pierre Luminet – take some time to find and look at them, it's super impressive what they achieved using that e

One side of the accretion disk is indeed brighter than the other – in the default view in the app, the bottom part is brighter. The effect appears quite clearly visible to me, although the exact contrast depends on the colorscale mapping. H

Thanks for sharing – as someone who studies black hole environments daily, I didn't even think of such a phobia existing! I wonder if some tricks, adjustments are feasible, to minimize the effects of these phobias? I see these visualiz

Looks interesting from the first glance! I should probably try that game – having both the artistic and realistic pictures in mind :)

If this app turns the entire screen black, this probably means WebGL is not supported :) Black holes don't really "suck in" light. Whatever falls onto the black hole itself gets deleted, of course – but otherwise, it bends li

In my experience, on Android, it definitely relies on camera: AR doesn't work in dark room, and barely works in slightly-lit room. So it must be fusing camera + accelerometer + ...
