3 Prevalent Themes
1. AR tracking relies on phone sensors & SLAM
"First time I have AR’d. That was cool. How does it keep the hole in the same point in space as I walk about?" – hahahaa
"Your phone has an accelerometer, which can be integrated twice to result in slightly accurate dead‑reckoning; just keep accumulating 3‑vectors with every time‑slice. That's a helluva lot easier than visual cues." – boothby
"\"SLAM\" is the term to google." – dmd
2. The simulation is marketed as “physically accurate” but is heavily simplified
"Its titled a \"physically accurate black hole\"! Please don’t do this, if its intentionally not physically accurate and heavily simplified!" – 20k
"The accretion disk shouldn't be red, people just expect it because it looks cool. Black‑hole accretion disks are near universally hot enough to be blue." – 20k
"The rendering is also done without taking into account sRGB, and its colours are wrong… the doppler isn’t terribly accurate." – 20k
3. Black‑hole visualisations trigger genuine fear / “melanoheliophobia”
"If somebody feels no fear while zooming towards a black hole, their brain has some strange wires crossed." – chamomeal
"VR is fine when it's small cute bunnies… but a massive thing that tricks my brain like the edge of a gas giant is terrifying." – dluan
"Melanoheliophobia… the Greek term is “mayri trypa”, literally “black hole”." – stavros
