No it would burn brighter from more hydrogen fuel. However, you could extinguish it with enough iron. But it would explode when you do.

>>11198865
What if you throw antimatter at it?

>>11199057
How much?

there is already water on the sun fyi

>>11198865
Large mass gaseous fusion reactors do not explode.

>if I throw a massive amount of hydrogen and oxygen at the sun will it go out?
Lmao

>>11199060
Idk lets say half the radius of the sun

>>11199099
Half of the mass? For a moment it's gonna be the brightest object in the universe.

>>11199116
Half the radius baka!

If you had a ball of water the size of the sun, or even half the size, it would probably turn into a star just from it's own mass

>>11199129
It doesn't work like this, silly.

>>11199140
Yes it does!
I want my anti matter ball to have half the radius not mass you baka!

>>11199148
To tell you what going to happen I need to know the mass of your ball and to calculate mass i need to know it's a density. I don't know what is your ball made of. Is it antimatter balloon with anti-helium, or maybe it's ball of degenerate antimatter? If it's a ball of anti-sun with half it's radius, it will match super nova explosions at least.

>>11199148
Actually I just found a perfect place to ask your question

>>11199165
It is a anti matter sun half the radius

>>11199134
>Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away.

Theres a really simple method to this:
1. Ship water into space using a space elevator
2. When the elevator doors open at the top the water freezes as it enters space
3. Construct a tube of frozen water pointing at the sun
4. Repeat steps 1-3 using all the water on Earth. Has to be big enough to extinguish the sun, so you’ll need alot of water.
5. Give the ice tube a big push, as theres no air in space due to friction, the tube will keep moving towards the sun due to inertia
6. As the ice hits the sun the water will turn into ice, extinguishing the fire on its surface
7. Once extinguished the fighter cannot be restarted due to the moisture

I have a different question. What if we dumped a synthetic element into our sun to broadcast that we exist to anyone with a spectrograph?

>>11198856
it could, but you need really cold water. like minus 10 billion kelvin

>>11199257
>Negative kelvin

>>11199247
why would you need to ship water into space? use asteroids

>>11199252
Lol
>He forgot about the light years

>>11199099
Check your units retard

retard pseuds

if you put enough water in the sun, it would eventually cool the sun enough that fusion would stop, due to the temperature differential between the water and the Sun

>>11198856
No, because the water would evaporate before it touched it.

>>11199573
That amount of water becomes a star in its own right.

if you used enough water it would put out the sun, but then you'd have a sun made of water, and since space is cold it would freeze and you'd have
a sun made of ice

>>11199234
What antimatter?

>>11198856
Water extinguishes fire by excluding oxygen. The Sun is not burning, it's a fusion reactor releasing energy.
This is science for 10 year olds.

>>11199649
I'm not sure that's correct: for (essentially pure) H2 gas, gravitational forces cause the gas to compress, until it reaches the temperatures/ densities it needs to ignite fusion, at which point it sustains hydrostatic equilibrium

Water, by contrast, is nearly incompressible, so I don't think it would heat up and ignite like molecular clouds do

>>11199573
You could have a huge star load of ice cream. It's still gonna heat up at its core under its own gravity and start fusion.
You're either trolling or you're 12

>>11199699
>what is the Chandrasekhar limit

its like they let any retard freshmen post on this damn site. I can have more than a solar mass, and I can promise you that no nuclear fusion will ever take place: ice cream or rock, or whatever

Its hard to say because nobody knows how big the sun is

>>11199724
lol

>>11199116
Would it all annihilate or would the explosion just throw the matter and antimatter apart?

>>11199691
Your mums ass.
Wtf do you think retard?
I literally said antimatter sun half the radius.
It can't get any clearer you autist

>>11199694
>Water, by contrast, is nearly incompressible

>>11199262
>Kelvins can't result in negative
found the brainlet

What if the moon collided with the sun, but the moon was made out of CHEESE?

>>11199723
>Zero nuclear fusion happens when a mass collapses into a neutron star or black hole
Okay retard. Besides, water and ice cream are light enough that fusion is guaranteed as you're adding the mass. You can't instantaneously have a chandrasekhar limit worth of matter in one place. The only way to get around this is to use something that won't fuse before a collapse happens, like iron, which was mentioned before itt.

Doesn't the sun have lower energy density than mammal tissue or something?

>>11199239
I think he means liquid water the size of the sun in a sphere

>>11201589
High pressure != highly compressible. hydrogen obeys ideal gas law PV = N kb T -> can compress to high densities. Water does not. try doubling pressure on water, how much does volume change?

>>11198856
Probably, but its going to take a lot of water. Like 100 full size pools a lot.
