What do you think will happen if or when the sun "blows up"?

Question

every star blows up at some point in time when do you think our sun will? wat do u think the results will be? how long do you think people on earth will last? and when the sun turns into a "red giant" do u think our sunlight will be red? do you think all the planets will collide due to the loss of the suns gravitational pull??

Answer 1

I only wish that most of you would take the time to read some reference material from a reputable journal or text on astronomy, or do a course at college/school. Why?.....so you would know what you're talking about when you answer people's questions. It would also help you to formulate decent questions as well. Don't go getting your facts from TV shows or other places like many magazines, newspapers etc. They're invariably wrong and many times have erroneously added info.

The Sun will not explode. It doesn't have the mass to generate the conditions in its core to begin with. What the Sun will become in another 7 billion years is a Red Giant. By the time the Sun leaves the Main Sequence, in 5.6 billion years, it will be about 2-2.5 times brighter and nearly twice its present size. It will then leave the Main Sequence and be a subgiant for about 500 million years. The Red Giant phases will last for about 700 million to 1 billion years. And it will go through 3 phases as a Red Giant.....the initial phase where it'll expand to probably 60-70 solar radii (between the orbit of Mercury and Venus) and be M class. It will then shrink after the Helium Flash occurs in the core to around 10-30 solar radii and become K class. As the helium burning phase and build up of the carbon/oxygen core occurs, the Sun will eventually expand out to about 100 solar radii (just beyond Venus) and then begin to puff off its outer layers, in prelude to becoming a planetary nebula and white dwarf remnant.

By the time the Sun even looks like reaching out to Earth's orbit, it will have lost 10-15% of its initial mass, and consequently the Earth will have moved out into a larger orbit due to the decrease in the Sun's gravitational pull. Venus may even make it, but it's unlikely. However, what's left of the Earth will be nothing more than a melted slag heap. It may develop a new atmosphere after the Sun becomes a planetary nebula and dims down, but if it does, it'll very quickly freeze out as the Sun becomes a white dwarf.

That's the jist of what will happen.

Answer 2

Lets say the sun didn't become a red giant, to answer your question with better detail. First you would see a bright flash 100,000,000,000,000 times as bright as a candle, 8 minutes after the sun does blow up. then you would feel a hot wave and the trees and vegetation would burn and the oceans would at first boil, then evaporate away. After about three hours the earth protective magnetic field would be gone and the earth would be impaled with UV and X rays and life would cease to exist, if any still lived. After all this earth would become a boiling ball of lava and eventually rip itself apart. The sun would then shrink to a white dwarf the final stage of a star the suns size. However if we look into the red giant and don't skip it like i did in the first scenario, then we wouldn't last a day after this happens and the earth would be long gone, if we were able to move the earth so the red giant didn't kill us then yes the light would most likely be red.

Answer 3

Our sun will never blow up. It will go through the normal sequence of star degredation and eventually collapse into a white dwarf. It will not go Nova, it will not produce a super nova, nor will it collapse into a black hole - it simply isn't large enough or hot enough to do so.

When the sun turns into a red giant, the inner three planets will be engluphed, so we won't have any sunlight at all - there will be no planet here to see it from. As for the outer planets, their temperatures might change slightly, but their orbits shouldn't be greatly affected.

Answer 4

Well it is a fact that it will expand to be huge and "swallow" or engulf all of the planets in our solar system. But this is millions (maybe billions) of years away so it's no big deal. I think it's obvious that if the human race made it that long, we will have space traveled to a new galaxy with our technology - there is no doubt. The odds are probably against our race suriving that long, however. No, we won't have red sunlight, by the time it turns red, the Earth will be completely gone. Imagine the sun 1000 times bigger in size. Goodbye Earth. Don't worry - I think it will probably be YOUR great great great great.......x1000......great great great granddaughter who develops the technology to travel at the speed of light and move to a new planet!!!

Answer 5

We will get around 8 minutes of warning, as the sun is approximately 8 light minutes away from us. After that, our planet will be a smoking ruin and all life will be dead. if we have any atmosphere left, we might see the red sun. Planets probably won't all collide, depending on where they are in their orbit, but the inner planets will be toast...

I of course will be off on the mother-ship...

Answer 6

Meteors hit the Sun all the time. The Sun is way to large and massive for tiny meteors to have much effect, they would vaporize before getting there anyway. Comets are documented to hit the Sun often, they are more massive than meteors, nothing happens (to the Sun).

Answer 7

The Sun is a constant fusion of atoms and it has been burning since the evolution and creation of our Earth. I would safely guess that it will be around for a while and honestly the creation entity is how the world will end.

Answer 8

Not every star blows up. And it's been proven that ours wont ever explode. It will expand, to such a size that our planet will be engulfed in it. But after that it will shrink back down until it eventually becomes and dark, cold solid piece of carbon floating around in space.

Answer 9

in 5000000000 years sun will become red giant and the Earth will be no more, but sun will never blow because it is a small star.

Answer 10

Hopefully, the majority of humans will be off exploring the rest of the galaxy by that time. Otherwise, you won't feel a thing. Just suddenly, there's this angel saying "oops."
