THE BEST BUG IN THE GAME!!! Universe Sandbox 2 

Ok, you probably know what and why the game is doing this, since if you have an extreme knowledge on astronomy and chemestry, you also probably know about computer programming. But since you did not go into full deph detail on why that happened, I will give myself the benifit of the doubgt so I can say why. When you increase an objects mass to a certain point in this game, it turns into a black hole (eventually, when you raise it high enough), as you already know. And usually, the game expects realistic to be on when you increase the mass of a star to stupid amounts so it will go supernova, when it goes super nova, the original star gets replaced by the result, in the case of the black hole, this tells the game that a the stars glow is gone. But, when you have realistic off, instead of getting REPLACED by a black hole, it TURNS INTO one, and when the game does that, it forgets to remove the stars glow. This is also why the black holes glow depends on the color of the star.

You've got my subscription. I LOVE LOVE LOVE the video's you do! I'm no pro at space, but I am obsessed with it enough to be called an enthusiast. You make explanations very easy for me to understand when they are overly complicated, plus give me tips, tricks, and hints for universe sandbox 2, so it is a win win situation for me! Keep it up, brother!

it hit the "Petrov limit" haha

Its like Insterstellar (The movie)

that explosion could destroy the milkyway

I made Jupiter the exact size of the Milky way and this happened

Its just trapped light. You can trap light with a black hole making it travel almost infinitely around it, untill some of it finally escapes and its that lighht that you can see. With a mass like that you can acturally orbit light. Its pretty normal for black holes, but usually the iris isnt that visible on smaller black holes, but with that mass you can acturally see alot of it.

Can you have like a series that you just screw around in universe sandbox Maybe take suggestions. Like if you agree :)

its called a white whole, it spits stuff out

Anton: And a bunch of color thingys Me: HE SAID THINGYS

This is due to the plasma around the black hole heating, and basically generating the luminosity of a star.. Programming wise, this is because it keeps the stars original properties and "forgets" to remove them. So in fact it is a bug, BUT it is supposed to happen to all black holes with a lot of mass on the edge of the event horizon. The pressure will simply turn it into plasma and create these rings.

Working as intended, no bug

Can you make a Massive black hole (as Massive as the milky way) to crash into the milky way?

Betelgeuse is also my favorite :3 got his deklination tattooed onto my collar bone :D

I tried going back to this version, doing the glitch, and then exporting the object, to see if it would still work if imported into the current version. Unfortunately, though, it just became a normal black hole.

That’s the Black Hole photographed in April2019

Well the thing in the center is definetly a black hole , but since the realistic mode is turned off i think the stars sheds off it's light particles and creates a apparent horizon . Meaning the thing in the center is particles with mass , the outer ring around it is the light of those particles . This is only speculation correct me if I'm wrong

When I was watching the effects of this thing, it brought to mind KIC 8462852.

congrats you created a new universe

I think they fixed this, because I tried to do it, but the star just turned into a black hole without a halo.

Ah, I've been meaning to google what happens if a black hole gets too full of light. I read the comments and learned XD

its 2018 andi experienced a similar bug where i grew a star into a galactic sized black hole really fast with a bunch of objects around it and it left a halo with the orbits still visible as all the planets that were in teh raduis of the black hole got sucked in, i had the orbits on and saw an implosion of lines. turned off orbits and the orbital lines disappeared from everywhere but inside the black hole. im thinking rather than a abug it may just be how the software operates but i could be wrong

could be useful to represent the hawking radiation

I think that it haves gravity to a point were only a few quantity of light can scape of the star, the light on the edges of the view point.

I do believe that what your seeing is the light from the original Star frozen at the event horizon. theoretically speaking, anything falling in to the event horizon should appear frozen in time to us (you would see a shell of stars around or own galaxies supermassive) and your black hole formed pretty... oddly when your start suddenly reached yen times a galaxies mass. it's possible that the light from your start got frozen on the event horizon before the hole had a chance to swallow everything.

That black hole with your favorite sun... yeah, it already looks like it has an ... increasion disk

with the pulsars it looks cool

You should make a small star with planets orbiting around it orbit a huge star.

the dilation around a black hole is called gravitational lensing.

I'm no astrophysicist, but I'm pretty sure the halo is the photon sphere of the black hole. Since inserting a black hole doesn't insert light as well, but when you collapse a pre existing star, it's got light to create the photon sphere. By the way, the photon sphere is the closest point at which light can orbit a black hole stabily. Please correct me if I'm wrong.

Anton, I'm pretty sure that this is supposed to happen. Its the halo of the energy left from the star/body that it used to be. Movie Interstellar had a similar black hole.

It's called a quasar. Super massive black hole that when it passes through galaxy or nebula it sucks everything that is unlucky enough to be in the gravitational field. The mass is spinning around sort of like orbiting around the black hole and due to it's high speed the mass is heating, hence it eliminates. Btw this is just a theory about quasars, so let's not get all jumpy and excited, e.g. previous theory about quasars was that they are galaxies mixed together creating one bigass galaxy.

you can see that this thimg is a black hole because the escape velocity is above light speed

The gravity is so strong that even light can't escape...

isn't something at least like that supposed to happen where if its big enough than it would have enough mass to have such a high gravitational pull and density that even light cant escape.

that halo is just stream particles that where emitted from the object and now orbit the black hole

Wait so if it's 10 times the size of the milky way then how do u still see the next arm of it

it is a quasi star (maybe). quasi stars core is made out of black hole

it's a supernova orbiting the black hole at no speed and at infinity at the same time!

Interesting glitch, quick question though. If you turn it back on realistic mode does it explode or does it behave like a black hole?

It looks like a galactic supermassive black hole, but without all the stars around it. Except the glow would be stars? I dunno.

There is a weird thing going on when I try to do this in Universe Sandbox TWO. Instead of it saying, 'realistic mode', it says 'calculated radius'. Is there any way I can fix this?

well, you turned of the "realistic" what did you think would happen., that like disasembeling a lighter, remove the saferycap, turn the thingy several loops rather than max 1/4 a loop and calling it a "defective product" when the fire coming out is a feet tall.

Such a good bug!

omg he said Beetlejuice three times run for the hills sidenote, it it possible to create "glowing" particles? not the ones from a star collapse, but like the ones you made orbiting the black hole

I am guessing this is a star that has almost reached it's Schwarzinger Radius, but has got a part of it's surface still outside of it. I was wonder what that would look like, if this were to happen, since it can't really occur in nature unless we're dealing with Planck masses, and I doubt we'd be able to observe single quanta. (I've wandered off topic...) So yeah, without doing some calculations, it seems that that is indeed what has happened. On a side note, I doubt that Universe Sandbox² models Photon spheres or Quasars (yet). If it did, it would've been stated in the changelog.

It could be a black hole with a white hole outer layer, just one of my creative ideas

I think you created a Quasar, sort-of-speak

Heh, Is this, the other side of a black hole? Houston, we've located the Star Gate. I wonder if that black area is simply light that is emitted in the nonvisible spectrum such as infrared, X-ray, etc. Can you view this object through various lens from the nonvisible spectrum?

I made this bug occur but the black hole was the size of the universe and the white glow kept expanding and expanding until i zoomed out so far i couldn't see our own universe aka the black hole i made and only the white glow was shown. XD

Can it be, cuz it is supermassive that atracts even the light, so it's a black sun?

Reminds me of Gargantua

That's what happens, when any large does when it gets too much mass. This goes to show how much u know about the universe, because this is a simple law of any star.

Guys, you can still make it by adding a black hole. Click on it. Go to Appearance, and there is a thing called Color. If you change it then you will be able to see a halo around it! Hope it helps! :)

That is very similar to a black hole(except it has light)

That looks exactly like gargantua in interstellar

didn't you turn the realism mode of when trying to mix the black holes?

"If you're a developer you may want to get this checked because this is definitely a bug" 😂

7:21 YEAH LETS PARTY!!! XD

what if, its not a bug, and it actually happens?

You should one day try and create a galaxy from scratch.

beautiful

That is Sahaquiel the 10th angel.

scientist say a star the size of the entire solar system would absorb its own light so a star the size of the milky way should do the same

Seems like it would be real. Something so big would also have a massive amount of gravity. so much, most light particles are not escaping. Technically it's so massive it turned into a black hole

it also looks like a solar eclipse if you get further away from it *Hmmm*

bug bug bug!

you can do a sharingan with 4 of those

Home, home, home! That's right -- I said it three times, too!

and they said it took hundreds of hours to render individual frames

That's a Quasi-star!

could it just be a star but the program has calculated escape v to be the same as or greater than light speed.

I had a bug and the black hole was even bigger

I don't think that black hole was almost twice as big in mass as the milky way

The the blackhole on interstellar

You just...made a Disco.

I got this guys, I'm pretty sure this is what is known as a gravastar. just wiki the cosmological term.

+Anton Petrov This video made me go watch Interstellar... Was not dissapointed

You see Saurons eye I see an eclipse

Reminds me of Eye of Terror from Warhammer 40k

Beeteljuice, loved that movie

Mr. Petrov, I think this object that you call a bug maybe this class of object. en.wikipedia.org/wiki/Quasi-star

My Favorite Star Sirius B

11:58 is like coliding black holes!

That bug has already been fixed a long time ago!

This not a bug, you should read more about "direct collapse" - which hope to answer the question chicken or eggs, in cosmic scale. This what happen when a star receive alot mass from surrounding dust and gas, so much that the star keep gaining mass until the star reach it breaking point and turn into a black hole. And this happen alot when the universe was young. and since you turned off realistic, the star cant explode due to it enormous mass and at the same time, a black hole form inside the core of the star resulting an object that has even-horizon and emit light at the same time.

nice

Realistic Mode is gone, how am I still going to be able to do this? I want my black hole to be with halo...

but if it was an halo then you wouldnt see black that clearly at all i guess, cause whats on the side also should be in the front and on the back since it is a spherical object

Would that be a hypermassive black hole then.

I think they call a black hole with that effect, a quasar.

Plz help me the bug isn't working for me!

Can you explain why adding a black hole to a simulation with 0 or -X gravity makes it supernova?

I think it's orbiting light, because of that mass. Anyway, realistic is off so... Not their buisness I guess

This might not be a bug. I think because you increased the mas so much the gravitational pull would have been huge so It might have pulled it's self to get her crushing itself therfore creating a black hole

Am I the only one whose mum did not appreciate me watching black holes XD

Binary Black holes are a thing

matt shea did this glitch also i think it is supposed to happen not a bug i am not astronomer but here's what i think: i think that the core gravitational force decreases which makes it's weigh and mass decrease which makes it so small that it made the core black hole and i think it didn't adsorb the outer layer of the star because it was apart of it and if it absorbs it it would lead to it absorbing itself idk i am saying straight bullshit

i think this is a black hole with his event horizon.

I think it's some sort of quasar.
