I remember like 10 years ago when Occulus first came out there was that space simulation demo where you could go around the solar system in VR. You could also "fast travel" by zooming in towards a planet, moon, blackhole. Yeah, that was the day I learned I have a deep, crippling phobia of large objects. And Melanoheliophobia, which is fear of black holes. The only other time I've felt that way was snorkeling once nea…

I'm exactly the same. This one really give me the ick: https://www.youtube.com/watch?v=usYC_Z36rHw

> Its titled a "physically accurate black hole"! Please don't do this, if its intentionally not physically accurate and heavily simplified! It also doesn't exert the gravity an actually accurate black hole should :) And also, even on a phone with two cameras, they only cover a part of sphere – while a real black hole would bend light coming from all 4pi directions. Some simplification is generally required ("the map…

“Physically accurate” indeed raises the bar significantly. You’ve already done great work here. That said, the feedback seems to come from someone who spent considerable time analyzing your work. Even if only a few of the suggestions are ultimately valuable, that’s still a meaningful contribution and worth considering.

Sure, most of the raised questions are reasonable potential feature additions to be made – things like rotating black holes, or linear brightness-to-screen-pixel mapping. They just aren't "inaccuracies", in my opinion.

> Melanoheliophobia Tangential, but this being a nearly word-for-word translation of “black hole fear” made me realize how odd it is that we insist on latinizing these things.

I've also wondered the same thing about healthcare and other fields. All the complex sounding phrases are child-like in simplicity in their "native" tongue, yet completely indecipherable to most people in modern times. Quite a weird and undesirable path we ended up going down through inertia.

It's useful to search for the same thing and get results in different languages

For anyone that experiences the same, how do you feel about this picture? https://antichamber.fandom.com/wiki/Eye_Wall?file=Eye.png

It has always scared me and I believe it's for the exact same reason. It's possible it invokes no feelings on you if you haven't seen it in context (in the game it's from) so I'd like to test this

>of course this is a simplified visualization Its titled a "physically accurate black hole"! Please don't do this, if its intentionally not physically accurate and heavily simplified! The general public on here don't know better, and it takes someone else with years of experience simulating black holes to dig through your code to show what you've simplified. There's like a few hundred people who have the right experi…

>and they didn't know any better.

i think an "astrophysicist at Harvard's Black Hole Initiative studying quasars and black hole environments" who "work[s] with raytracing/radiative transfer simulations professionally"probably has a decent understanding of what's going on...

If somebody feels no fear while zooming towards a black hole, their brain has some strange wires crossed. Strongly recommend Outer Wilds. Falling into the black hole the first time was one of my most scared moments in gaming. I was totally panicking lol

The Outer Wilds is one of the greatest gaming experiences of all time. I would love to forget all about that game to just experience it again from scratch.

"an astrophysicist at Harvard's Black Hole Initiative" He probably knows. It's in a browser, there are probably some trade-offs. Calm down.

Keep your need for simplified representations of reality (which claim to be complete) out of our information-based community.

From an information theory perspective, isn’t a representation by definition a simplification?
