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…

Same. Especially with circular objects. Placing the black hole in my room using the AR mode was very distressing for me

It was actually after that VR experience with large black circle that now when I look at photos of the inside of Hagia Sofia I get a little heeby jeeby creeped out lol.

If anyone's interested in the accuracy, this is very 'visualisation grade' software. Its a bit of a pet peeve of mine that people present these sims as being very physically accurate, when they contain major inaccuracies, some of which are very obvious and/or deliberate. This one has some serious physical limitations I wouldn't mind at all if it didn't say that this was a *physically accurate* black hole specifically…

Love, Death & Robots: Black hole used red for the disc, too.

On a related note, there's an annoying mistake in one of the Fatalities in "Mortal Kombat 1": Liu Kang teleports with his opponent into outer space, summons a black hole with a snap of his fingers, and throws the poor sod in. But the accretion disc is red where it rotates towards camera, and blue where it rotates away!

Well I thought this is a real black hole. Forgive my ignorance. But what would it take to put a fist sized black hole in your room.

According to this calculator [1] it would take 11.274 times the mass of the earth to create a black hole with a radius of 10cm.

I clicked on this because I worked on the infra that simulated the famous blackhole sim in interstella. I thought "oooh this is interesting I wonder how they are going to do physically accurate on an end device" Recalling how the original particle sim was something like 100TB, took 2 weeks to generate and seemed to write in a way that killed disks. but that was >10 years ago, so what clever stuff has been done to mod…

Someone refers to a sci-fi-esque (more imaginative than scientifically accurate) virtual rendition of an interesting scientific phenomenon (black hole) in a fanous sci-fi movie (Interstellar), in their scientific analysis/critique comment on a HN thread about the virtual sci-fi-esque rentition of such a sci-fi object (black hole)(yes, a simplified easy-on-eyes pseudo-accurate rendition of a black hole, for VR/AR immersion at home, counts as sci-fi-esque, IMHO), and someone else who worked on such famous object (black hole) depicted in that exact sci-fi movie, responds to the comment.

Peak HN, right here!

I think you're being very harsh. I read it as a side project of a scientist meant to entertain as much as educate. Holding it to the same standards as the Event Horizon project seems pedantic and excessive.

> Melanoheliophobia, which is fear of black holes

Thank you for mentioning this. I am an avid space nerd. One day I decided to try Space Engine, and one of the first thing I did was get warped to a black hole. Seeing a literal hole in space time appear in front of my screen was one of the most terrifying things I've experienced. I Alt-F4'd, and never opened that application again.

It's like every single atom, nay, every single subatomic carrier of information in my body was telling me to stay the hell away from that.

Earlier quoted context omitted.

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

Outer Wilds is exactly what came to mind for me, too. Made a jump...missed. Thrown into a decaying orbit around the black hole. Absolutely terrifying, and panicking didn't help in the least! And getting close to the upper atmosphere of Giant's Deep for the first time, staring, thinking about the atmospheres of real-world gas giants, knowing that I need to take the plunge. That game exposed some phobias that I'd only…

> And getting close to the upper atmosphere of Giant's Deep for the first time, staring, thinking about the atmospheres of real-world gas giants, knowing that I need to take the plunge.

I recommend the game Exo One then.

It's a surreal game of flying a spaceship around in the atmosphere of a gas giant. While beautiful to look at, I know enough that flying around in a gas giant is so terrifying a prospect I never managed to complete the demo of the game. "Oh, how do you falling through pitch black clouds with winds in the 3000+ km/h where it's raining literal diamonds until you reach a lake of supercritical fluid at extreme pressures?" You don't even have to go very far, there's 4 of these in our solar system alone.
