Do you think that one day, the sun will stop shinning?

Question

The possiblilty that the energy of the sun will be over?

Answer 1

Its not a possibility its a reality every star will eventually burn out. but just before it does it will expand to such a size that it will engulf our entire galaxy swallowing up all the planets. So dont worry you wont be left in the Dark ( a boom boom) but its not due to happen for a few million years yet

Answer 2

In theory, that is an eventually event. But who knows, when... ? It is estimated to be such a long time later that maybe human race have long vanished by then. Have you watch the movie "Sunshine" ? Who knows? Maybe before the sun dies, someone, either human or other alien, will try to light it up for purpose only they knew. Or maybe by then human no longer need this star we called Sun. Maybe by then we have decided to live in another paradise world. There may be even brighter and nicer shinning stars. We will never know. This is beyond our control and as a normal human being, we should not be worrying about that for now. Even Scientist won't worry about it for the next few million decades, why should we? There are far more things to worry about than whether the sun will stop shinning. Who knows, maybe in the very late future, human will be so advance that we will create our own "sun" or maintain the "old" sun for future generations... Sigh.. I think too much... lol... Cheers... º¿º

Answer 3

Yes. But not for tens of billions of years.

The sun shines by 'burning' hydrogen. At the center it is a massive hydrogen bomb. It's been burning hydrogen for 4.5 billion years and this will last at least another 4 or 5 billion years.

When the hydrogen is 'burnt' in the nuclear reaction, it is transformed into helium. Eventually there will not be enough hydrogen to fuel the sun and without the burning at the center, it will start to collapse under gravity.

Once it collapses sufficiently, the pressure will build up enough to 'ignite' the helium that was left over. Then it will start shining again but will now be much redder and it will swell up and swallow the inner planets - maybe even earth.

This kind of star is called a red giant.

Eventually the helium will be used up too and because the sun is not very big it will not be able to start another cycle of burning If it was bigger then it could go on to burn left over carbon and eventually it would explode and leave a black hole behind.

Our sun will stop burning at the helium stage the sun will shrink down to the size of the earth but with massive gravity!

This kind of star is called a white dwarf.

It will stay like that for billions of years, cooling slowly and gradually stop shining. It could continue to be visible for tens of billions of years.

So it will stop shining - but not for billions and billions of years

Answer 4

Yes.
Sun is (almost) 5 billion years old.
In another 5 billion years, it will expand into a red giant. It will NOT explode. However, it will expand quite a bit and its surface may extend to Earth's orbit (we are not sure how close, because in the mean time, Earth's orbit will have expanded a bit). It will throw off its outer layers (this will not be good for us if we have survived the red giant phase).

Being too small to trigger Helium fusion, the Sun will settle to become a white dwarf (going from red giant to white dwarf will take a few billion years).

After quite a few more billions of years, it will cool: brown dwarf and eventually, cinder. By then it will be about half its present mass, so nothing more can become of it (not massive enough to become a black hole or to explode or to have occasional nova episodes... nothing).

Answer 5

This is not a possibility, it is a certainty. The energy produced by the sun comes from a nuclear reaction between hydrogen atoms combining to form helium. The sun contains a finite (but very large) amount of hydrogen atoms - once they've all been converted to helium then the sun stops shining (the precise process is more complicated, but in simple terms this should convey the general principle)

Answer 6

yes. remember, the sun is a star. right now, the sun is about 5 billion years old. it's life span is about 10 billion years. so the sun is half way through its life. currently, hydrogen is fusing together, changing it to helium, and about half the hydrogen is gone. so in 5 billion years, all the hydogen that supplies the sun's heat and light will be gone, making the sun blow out into a red giant star. when this happens, the sun will engulf mercury, venus, and earth. that will be the end of the earth. then, the sun will shrink down into a black dwarf. that means that the sun died.

Answer 7

Of course the sun will be over because the sun is a star and all stars die out. I asked a similar question and ppl said that the sun will first turn into a red giant which will eat up all first 3 planets including Earth and we will die. You can look at my question for more answers. :)

Answer 8

In 4.5 billion years the sun will start to expand and destroy the inner planets, earth will fry and that will be the end of us. So not much to look forward to is there ? OK it wont worry me, because i shall have left this place and populated a new planet billions of miles from here. You see i have the answer to eternal life, and if you match the criteria I'm looking for you can come with me !!!

Answer 9

Hello,

(ANS) The sun & the universe were created approximately 200 billion years ago, the earth is estimated to have been formed 60-70 billions years ago.

FACT: The sun will die at some point in the distant future as it runs out of its nuclear fuel. When that happens or starts to happen our sun will turn into a "red giant" a massive object that will eventually explode & cause a supernova or implode upon itself until it becomes a dark lifeless object with super dense mass.

HOWEVER!!
I think you can relax for now as the sun (our closest star) has another estimated 200 Billion years remaining. The sun is only a teenager, its coming close to about half way through its life cycle. In cosmological terms this is nothing, a mere blip.

Answer 10

All stars eventually burn out, due to a lack of fuel. The sun is no different. When I was in school, it was estimated that our sun would last for about another 2 billion years.
