Can We Make a Water Star? Black Hole? Gas Giant? - Universe Sandbox² 

Silvia Fox, I think we knew that...

Silvia Fox Just throw a bunch of iron at it. It'll screw up the fusion and prematurely end it, right?

I don't know that much about nuclear fusion within stars, but I think putting huge amounts of iron within a star could kill it. What I'd think you would need to do is put enough iron into the star so that it can't build up a layer of gas large enough to start fusion, so you would need an amount of iron slightly less than the mass of the star. However, that runs into another problem, because the gravity created by all of this iron would compress the star's gases even more, possibly starting up fusion again. That's my theory.

No, that wouldn't do it either. You would need a sizeable percentage of a solar mass worth of iron, and even then I don't think it would work. Remember the Sun contains 99.9% of all the mass in our Solar System, the other 0.1% is everything else combined, including Jupiter. The Sun isn't the same density as Jupiter, the sizes are therefore wildly untrustworthy. Even then the Sun dwarfs Jupiter by over a thousand times. Even if we got a solar mass of iron it would most likely collapse into a black hole due to the immense pressure. What keeps the Sun together are the constant fusion reactions. As soon as the fusion reactions cease the star collapses. Since there is no force sustaining this giant ball of iron I would say it would collapse into a black hole. Iron being made within the star is generally what does it, but even this our Sun won't achieve. It's far to small to get to that stage. To have a star fuse silicon into iron you would need it to be at least 3-4 times larger than our Sun. Our Sun won't get the privilege of going out with a bang. No Supernova awaits it. It'll go with a whimper and become a white dwarf which will then eventually die.

If a star is made of materials other than hydrogen and helium it will be unstable and likely explode.

like the kids in Africa that could have drank that water star

xddd bast junk ovf 202020

LEL IM THE ONLY ONE THAT COPY PASTED IT XD

stop

how to save afrika lets ask anton petrov to make then water stars.

True

Or yes

X D X

Harry Evett :o

Harry Evett ikr

no, you dont

Jacob Maiato I enjoy them a lot:)

Hello mars fan

He just colored the silicate with blue hahahaha

wow very stupid man very stupid WHAT IF IT WAS ERTH DUMBY

EARTH*

Foxy, what the hell are you on about?

foxy plush are you older than 12

?

He said in a parel universe not here

Equlex Still fcking dumb. Now in 2 universes.

Bozebilly how exactly is that dumb I’m just confused

Pay up

That would be cool ... but someone would have to make it unfortunately

Oliver Fanatis That make sense

Oliver Fanatis It would take a ridiculous amount of heat to fuse hydrogen and oxygen, only something like that ever happens inside the core of a star when it is dying and is about to go supernova

Oliver Fanatis Also, fusing Hydrogen and Oxygen would make Flourine. You get water when Oxygen BONDS with hydrogen, not fuses with it.

Y'all got it wrong, stars fuse atoms together, now how would that only happen if a star goes supernova? Stars fuse everything together up to iron. After iron the star will die. (Some larger stars will continue to uranium, and supernova afterwards)

Then why is there naturally occurring plutonium?

For optimum chemical reactions though you going to need to have equal molar amounts LOL

Queen Elsa of Arendelle Well a black hole has so much gravity it rips and compound and element down to the fundemental particles that make up matter.

Volka Gaming A black hole might drink me instead? Well... 😏

Queen Elsa of Arendelle it is entirely arbitrary what kind of material goes in to the formation of a black hole. It is the consequence of compressing a mass into an area below its schwarzschild radius.

In soviet Russia WATER DRINK YOU That’s the quote

Gia Huy GamingVN no they don't they are gas giants they may be blue but it's not water if that's what you're thinking about

never mind I got to the part where he says there is water on them sorry to be bother some

lightning the wolf animates Kittenscute theyre not gas giants actially theyre ice giants

if there's water in Uranus then you have diarrhea, because Uranus should be full of gas actually

Theodoяe Kяap and other stuff ;)

E Martin yep....

Zapper Gaming erase this for a second

Just for a second. No big deal.

He said “I think I’m going to ERASE THIS for a second”

Damn... Anton racist confirmed

genius

Yeah, I was thinking... That's not water...

tehs3raph1m mhm

Yey

He made a glass star? Sort of.

Yes

AgeofJP "Callin from Springfeel!!!"

Yes he has OCD

Recalcitrance game is still in alpha lol

The irregularly shaped body turns into a sphere as it gains hydrostatic equilibrium (tldr;its just becoming a sphere due to gravity and mass). I have no idea it turns into an ice world. As you keep adding more and more mass, it gets larger and larger until the mass is large enough to gain a few star like properties, becoming a gas giant. A gas giant evolves into a red dwarf as its mass is compressed further and further (you got to add more and more mass for this to happen) until it triggers the nuclear reaction that fuses Hydrogen further into Helium, violently flaring up into a red dwarf. So basically, it's all just different stages of gravity acting on mass.

Our sun is pretty fucking small in comparison to the biggest stars possible. Idk how wide the biggest stars are in comparison to the solar system but just to give you perspective, the biggest star compared to our sun, is the same as comparing the size of our sun to the size of earth.

unless your UY canis majorus no

That would be a normal planet core with just water around it.

Ravonies Ravenshir gallium?

Zapper Gaming no maybe out of molten tungsten

You mean the liquid mercury?

A star with anything heavier than iron is not self sustainable and will Just collapse

Ravonies Ravenshir Now THAT would be interesting!!

*Y O U ' R E*

Hay is for horses

plush and gaming and vlogs Lol

well they are called pulsars

If it has enough mass to fuse Silicon to Iron, then the star would collapse to a Neutron star or Black Hole, not White Dwarf.

Toby SO kill us ☺☺☺

+Smart Name The sun would collapse into a neutron star, I think.

Atoms! Atoms every where!!!

On the other hand, could you make a *fission* star using something like lead?

Haituga it was my mistake

Anton Petrov combined mercury with silicate and water just a suggestion

Did they ever seen a red dwarf dying/nova?

Have not been observed* Remember that.

Idk what you are talking about but at the white dwarf stage it does not explode it turns into a black dwarf then dies when the universe dies soooo...... we will have to live in a new universe.

Nice

Damn goku must be super saiyan 8273828173848392738262947302739372928749201730472936392647 to create a spirit bomb that large

he did..

Derp.

second saying first

first saying no one gives a fuck

second saying second

Third saying second

me saying nice username

1500-2100 times bigger ^^ not billions...

Anton Henriksson m8, vy canis majoris isn't the largest anymore

Anton Henriksson hey UY Scuti are more bigger than VY Canis Majoris

Uranus is 10 billion times bigger that the sun

ur so high you went past the heavens?

cuz science

This guy is cheating. Try it for yourself, do the same thing to an asteroid or a moon and you’ll see that the temperature will rise up so much in just a few years that your object will lose all of its mass and disappear before even becoming a gas giant. Anton is full of piss. He does that in all of his Universe Sandbox videos. Cheats behind camera every damm time and it’s just a waste of time trying to put his videos to the test. ‘What da math’ more like what a waste.

It's a mechanism of the program, but in a way also in reality. If you keep adding size to the virtual planet, it keeps it's average weight / mass , so a giant plant with a small mass is in average gassies. In reality do the effect depend on what you "add" to the planet, if you have a small amount of gas with nearly no gravity, can that easily attract gasses and dust and depended on the rotational speed of the captured, you can end up with a rotating "cloud". By adding water, or in reality ice, do you start with a lump that attracts more ice and so on, when the mass is getting over a certain point, the pressure from the gravity, start heating the ice and you get an water planet, by keep adding do you get more heat and thereby steam and you have your gas, if you keep adding you end up with a star. But a gas planet is a strange thing, you start in the outer "shell" with gas but if you keep traveling toward the center, do the gas get more dense, fare down will you meet HOT ice, also called ice 7, it looks like ice and behave like ice but it's because it is pressed extremely hard together. below that can you meat all sort of strange matter, and maybe in the center, will you meet a giant diamond!!

it'll happen! I just haven't found a better name

Oxygen burns it making its SO HOT it is on fire basically big fire

What you are describing is basically a Neutronstar

yeah you are right i just googled if there is a way to slow down light but there isn't :o

Try 'cosmic well'

But they live for a VERY LONG TIME

THEN MAKE THAT STAR GO SUPERNOVA

YES

Totally, though nice to know we (galactic scale) won't die of thirst!

BigBrotherMateyka poop

Buy it on g2a it's cheaper

Robert Gough yes as an example, the earth would have to be the size of a pea to turn into a black hole
