who here think the sun is going explode? if not why?

The sun is not massive enough to supernova.  The Sun will however eventually swell into a giant that will consume all the inner planets (when the hydrogen fuel is depleted 5 billion years or so from now) and then shrink into a white dwarf star.

ya every star has a time to explode but dont worry when the sun explodes they will be no earth.....

The Sun, in 4.5 billion years supposedly, WILL start to swell. It will get bigger, and en-gulp Mercury and Venus. The atmosphere will evaporate, water will melt, and life will be gone. The sun will swell enough to devour the earth, then shrink, grow, Turn into a planetary nebula, then shrink, for the last time, into a white dwarf. Then In a few billion years, cool down to a black dwarf.\n\nThe reason the sun expands, In case you want to know, Is because of its fuel supply. The energy from the sun comes from nuclear fusion of Helium. When the helium supply runs out, The sun has to fuse hydrogen, therefore making the sun swell. The sun then will Shrink, once its helium supply is restored, grow again, then cast out a planetary nebula (For what a planetary nebula looks like, Look up the ring nebula) then it wont have enough hydrogen to grow back to the normal size...and become a white dwarf. Eventually, it will cool into a black dwarf and die. \n\nAnd no, incase someone posts it, the sun will not become a black hole.

Hell no, all humans will die from some crisis or big disaster, or maybe the earth will be swallowed by some black hole (Actually it's happening) scientist found out that our galaxy is being sucked by some Massive black hole.\n\nI just don't want to be there when it happens :D

If we don't blow each others Countries up with nuclear bombs, the Sun will begin to burn up the Earth in about 4 - 5 Billion years.

How would we know? I am not gonna stay alove for a million years, neither will you. I don't mean to be arrogant, but honestly why should we care. I say live by the moment. Focus on what you are doing NOW. But if you really want an answer, I think now. You know what, it won't be the sun or a black hole that destroys us, it will be the human race, and maybe natural disasters. Look at the wars, we are killing eachother! In the past year earthquakes and tsunamis have outbroken wiping out even more of our civilizatiopn. We are only destroying ourselves.

very long. this is because the sun is a very large star and will take billions or rather trillions of years. when it does burn out however, it will be big enough to swell so big that it will swallow mercury, venus and possibly earth ^^ good luck

Who told you the Milky Way is going to explode in 5 million years?\nI know of no scientific evidence or opinion that offers the possiblity that the Milky Way will explode (what would cause it to explode???) in 5 million years.

this is an 11 year cycle of our sun. it will start revving up around 2008 and should peak around 2012.  we have had them in the past say about 22 years ago. If it dose happen the thing we need IS solar panels.  because the transformers on the planet will be taken out by power surges of the sun and we will be without power for as much as 10 years while they rebuild them. (we really need alternative energy then) but i really don't think it is something we really need to worry about.

probably not.  Unless the sun explodes

Hot topic! Woo-eee. This is one of the creationist versus non-creationist hot potatoes!\n\nHere's why, some creationists say if the sun were shrinking steadily, then a  long time ago, it might have been so big and hot as to turn the surface of the Earth into a pit of fire. So nothing would be alive, say when the Earth was a billion years old.\n\nScientists who study the Sun believe that it is a huge ball of glowing gases and matter. Gravity wants to pull all the stuff together, to shrink it. Heat from nuclear and other reactions in the center of the sun wants to blast it all away, to make it grow.\n\nThe Sun seems to have reached a temporary balance point and so it is the size that it is right now.\n\nSome observations were thought to show that the Sun was shrinking during 6 years of monitoring.\n\nOther studies show that the Sun might sometimes expand and shrink at different times. Just like a candle flame will flare up and then settle down again.\n\nThere are no mainstream scientists claiming that the Sun has been STEADILY shrinking since the beginning. They are only investigating to see what might be happening.\n\nSome astronomy research about the possibility of the Sun shrinking has been used by some groups such as the Institute for Creation Research as evidence for a young Earth. The idea being that this research agrees with their way of reading Holy Scripture. Their view is that the Earth is not very old.\n\nOther writers point out that the astronomy research about the size of the sun is interesting and important work about small-scale, and SHORT-TERM changes in stellar structure. And it may or may not have anything to add to the creation debate.\n\nMost solar research and theory shows that stars are initially formed by coalescing matter -- they shrink. But only until a balance is reached. Then over long periods of time stars might oscillate in size as different types of chemical and nuclear reactions take place. Some stars become super-giants, others zoom outward and then crush inwards to tiny sizes. \n\nThese are just theories based on mathematical models and observations of different sized suns and novas. No one knows for sure in a secular sense.

Our sun does not have enough mass or density to go nova.\n\n"The Sun is about 4.5 billion years old. it has used up about half of its nuclear fuel (hydrogen). In about 5 billion years from now, the sun will begin to die.\n\nAs the Sun grows old, it will expand. As the core runs out of hydrogen and then helium, the core will contact and the outer layers will expand, cool, and become less bright. It will become a red giant star.\n\nAfter this phase, the outer layers of the Sun will continue to expand. As this happens, the core will contract; the helium atoms in the core will fuse together, forming carbon atoms and releasing energy. The core will then be stable since the carbon atoms are not further compressible.\n\nThen the outer layers of the Sun drift off into space, forming a planetary nebula (a planetary nebula has nothing to do with planets), exposing the core.\n\nMost of its mass will go to the nebula. The remaining Sun will cool and shrink; it will eventually be only a few thousand miles in diameter!\n\nThe star is now a white dwarf, a stable star with no nuclear fuel. It radiates its left-over heat for billions of years. When its heat is all dispersed, it will be a cold, dark black dwarf - essentially a dead star (perhaps replete with diamonds, highly compressed carbon)."\n\n---and---\n\n"Our star, the sun, was born in the heavens about 4.5 billion years ago. Our sun is about 1/3 of the way through its expected life. Scientists are now predicting the following events during the remaining life of our star:\n\n    * 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.\n\n    * 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.\n\n    * 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.\n\n    * 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.\n\n    * 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."

Well we've been through and ice age and a flood. I am guessing our planet will go up in a bid ball of fire...explains the ozone layer hey?

I actually did hear about that in my college Astronomy class. I think it's pretty awesome. I mean, what if our sun burnt out. Maybe we could still have a significant amount of solar energy and radiation that could help us survive. I'm not sure if the star is old enough to develop life or not. It could have already developed it, and we just have no knowledge of it.

if explosion means bursting inside out, then nope, but population explosion has already happened, and global warming has reached the point of no return, so it is scary but true that there is gonna be an end to the mankind, when? i do not know, but how? disastrous natural calamities that is for sure. do not worry, we all are gonna die, so we all will meet in the heaven, if there is one, just do ur work in this world for now

i've already started packing.  i'm scheduling for 8am tomorrow.   \n\nHonestly I don't think anyone can really answer that.  If you are a person of faith then who knows other than when God decides.  If your not then you rely on all the brilliance of scientits, at their guesses I would guess another millenia before we completely wipe out all resources from the earth.  But until it comes to a complete end you have to be more specific, do you mean, end as in uninhabital and we have to leave it, or it completely is wiped out through some catastrophic event?  in the question of catastrophic event i would say 5 billion years (look to my resource link).\n\nIN RESPONSE TO...\nWOLF:  you claim that the sun will super nova in 9 thousand years due to universe facts.  well you have AMAZING universe facts considering that our sun will NEVER become a super nova.  even if it it where a star that would  super nova it wouldn't dry up our water.  come on, do you know what a super nova is?  if our sun exploded then there would be so much energy released that earth would more than likely be completely devasted to the point of utter inhabitation, oh and dry up our water.

The problem is that the universe is so big and we are so small.  I een heard that if all of the nukes on earth were sent into the sun and blown up at the same time nothing would happen, except the equivilent of a solar flare.
