Will our sun explode

Answer 1

According to our best understanding of astrophysics, the sun is expected to cease being able to sustain fusion in its interior in approximately five billion years. It will expand into a red giant and then collapse into a white dwarf, at which point it will still be very hot and remain so for many billions of years as the stored heat gradually leaks out, but it will no longer be producing new energy through fusion.

Answer 2

The Sun does not "burn", like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Nuclear fusion occurs when one proton smashes into another proton so hard that they stick together...and release some energy as well. This energy then heats up the other materials (other protons and electrons and such) nearby. This heating eventually grows out from the center (or core) of the star to the outside, finally leaving the surface and radiating out into space to be the heat and light we know stars emit.

People, including scientists, sometimes say that the Sun "burns hydrogen" to make it glow. But that is just a figure of speech. Hydrogen really doesn't burn, it fuses, into helium. So no oxygen is required!

(Source: See related NASA link.)

When things here on Earth burn, what is happening is that oxygen is combining with the molecules of the burning substance and releasing energy, which is the heat of the burning. Some materials give off more heat when combining with oxygen, some give off less. If a material does not readily combine with oxygen, or if the amount of energy released when it does combine is too low, we say that the material is not flammable.

What goes on in the sun, however, is not "burning" like here on Earth. There is no oxygen (or more accurately, no where near enough oxygen, there is a little) in the sun for any kind of normal burning to take place. What is going in is a process called nuclear fusion.

In the sun, hydrogen nuclei are fused together to make helium. This is similar to burning on Earth in the fact that two things are combining together to release energy, but different in every other way. For one thing, the materials involved are different. For another, oxygen on Earth combines chemically via the outer electrons with an appropriate fuel to burn, whereas in the sun, it is the nuclei of hydrogen atoms which are combined. The interior of the sun where this takes place is much to energetic for the hydrogen atoms to even have any outer electrons. Lastly, while chemical burning on earth releases only a little energy compared to the mass of burning materials, nuclear fusion on the sun releases a huge amount of energy compared to the masses of hydrogen involved.

But just like any fire on Earth, the sun can't go on burning forever. When all of the hydrogen has been fused into Helium, the sun will change somewhat and start to fuse the helium nuclei. This does not release as much energy as the fusion of hydrogen, however. This will continue through other elements until the only thing left is gaseous iron, and the sun eventually dies. Don't worry about that, though, our sun has another good 5 billion years left before it dies!

Answer 3

Answer:

Not for a few million years yet. Answer: Our sun is about 5 billion years old, that is about half way through its life.

In five billion years from now the sun will run out of hydrogen gas. This will cause it to grow about one hundred times bigger than it is now. It will then become a white dwarf after that then slowly cool down. EXTRA INFO: * In the next 1.1 billion years, its brightness will increase by 10%. This will super-heat our planet as a result of a severe greenhouse effect. All of the oceans on earth will boil away and all life will be destroyed. * In about 6.5 billion years, our sun will double in brightness and use up all of its supply of hydrogen fuel in its core. This will cause the sun to begin swelling as it uses hydrogen from the layers surrounding the core. * In about 8 billion years the sun will swell to 166 times its present size. This giant star will swallow up Mercury, Venus, and maybe even our Earth. Our sun will then be what scientists call a Red Giant because it will be very large and red in color. * After all hydrogen fuel is used, the sun will begin to use helium as its fuel. This fuel will burn very quickly and only last about 100 million years. * In about 12 billion years, the sun will eject much of its outer layers and become a smoldering, collapsed core that scientists would call a White Dwarf. This will certainly be a violent end for our sun and the earth. This does not, however, mean the end of the human race. If our science and technology capability continues to advance, we may be able to explore and colonize other worlds. Home, for future humans, may be billions and billions of miles from our home world of earth

Answer 4

Answer: Probably yes, about 4 billion years in the future, when the Sun expands into a red giant star. Mercury and Venus will almost certainly be destroyed when the Sun engulfs them, but we're not sure about the Earth. Certainly the Earth will be unlivable.

Answer: No, it won't. Our Creator won't let it get to a point like that; the end times because of His will will happen and it doesn't include the sun destroying the earth.

Answer 5

The sun will go out, in 4 or 5 billion years. it is using its suply of hydrogen atoms which only seven tenths of 1% is turned into helium atoms so the best estimate is that it will take another 4 to 5 billion years for the sun to go out

Answer 6

Scientists Say that the sun will die in about 5 billion more years (the sun is already 4.5 billion years old). The sun will die due to the lack of hydrogen that is nuclearly formed into helium...creating energy. Because of this, in the last few years of it's life (or even days) it will shrink as it's core shrivels up, then luminously flare into a red giant (which would reach out to Jupiter.) from then it would continue to burn of the rest of his energy before imploding and turning into a neutron star or white dwarf. But if the sun is over 8 solar masses, when the core collapses it makes a black hole.

So it's not proven...but its obvious

I hope this helped

Answer 7

It can certainly not shine forever. At some time, it will run out of fuel. However, long before that happens, it will get too hot for there to be any life on planet Earth.

Answer 8

it will suck in all planets then be come a white dwarf then it willtake billions of years to cool off

to the answer above... the question was "When will the earth die when the sun burns out?" not "what will happen to the earth when the sun burns out?".... umm the answer would be "YES" humans could not see any thing with out the sun.... it would be like we are all blind... not including that the earth could like freeze due to non heat ... so i would guess like 1-2hours

WRONG WRONG WRONG when the Sun dies it will swell 108x it's current diameter into a red giant it will consume Mercury and Venus but will spare the Earth however it will be so close that it's solar winds will blow away the atmosphere and the immense heat will boil away all surface water and liquify the surface, and many millions of years later it will shred it's atmosphere and compress to a white dwarf. However it is very likely that in 1 billion years Earth will be uninhabitable anyway (the Sun gets 10% hotter and brighter every billion years) so in a billion years the earth will be hot enough that liquid water will no longer exist on the surface no water equals no life.

Answer 10

no, our sun is too small. it will turn to a red giant and burn us to death. I bet we will be fine.
