What will happen if the sun just burns out?

Question

If the sun where to quit shining tomorrow what will happen? Would another star takes its place?

Answer 1

I can't think of a feasible reason for it doing that. It will burn out eventually, but not for billions of years. If it did now though, not much would happen right away. No other star would take it's place since we'd assume that it burned up it's fuels. As a plain ol' small-medium star, it wouldn't form anything exotic or go nova/blackhole. Mostly it'd just get really dark and then everything would slowly die off. We wouldn't float off into space, the gravity of the sun comes from it's mass, not the fact it's a star. Before it does eventually burn off in real life, it'll have expanded out and burned our planet to a crisp before it finally shrinks back down to a tiny husk of it's former self.

Answer 2

Why do people answer a lot of questions, if they don't know anything about the subject. Okay so the answer now. First of all, the sun doesn't burn, it undergoes nuclear fusion (hydrogen & helium molecules fusing together) When the sun would be, how you said, "getting older", then it would keep expanding. By the time it's already a red giant, I'll be so big that it'll be like where the Earth is now, so destroying the planets. Then when the sun stops its nuclear fusion, it'll collapse on itself, creating a super-nova and a black hole. It doesn't really matter because we won't be here anymore its gonna take billions of years. Also even before the time the sun will collapse most life will probably be gone because of all the heat. Hope this helped.

Answer 3

Yes the sun could turn off tomorrow or next year after all no one knows how long the sun has been in existence maybe it's time is near. But when the sun finally loses it's fuel It will not turn into a red giant and fry the Earth because that's propaganda by the mainstream scientists to scare people they have no evidence this will happen to our sun. It might turn into a white dwarf or black hole but the Earth will survive. Stop believing the sun will turn into a red giant it's to scare people no direct evidence it's all guess work.

Answer 4

Luckily, it's unlikely to happen. The nearest other star is in Alpha Centauri which is 4 light years away (as opposed to 8 light minutes to the Sun), so don't count on other stars to heat our planet. The Earth would get cold very fast and all life would start to die.

Answer 5

It would be very hard to stay alive. You would need to find a source of nutrition that doesn't depend on the sun. Maybe we would eat rocks? Then we would also need to take vitamin supplements because our body develops vitamin d? from the sunlight. And if the sun loss mass the earth's orbit pattern would be screwed up. Your best bet is just to find someone special and ...... :)

Answer 6

Actually, we would fry rather than freeze. The Sun will expand, turning into a Red Giant for a few million years. It may even become big enough to actually consume the Earth.

Answer 7

All life on Earth would cease to exist within a week. All life cycles on Earth are dependent upon the sun.

Answer 8

No! We would lose our orbit and fly off into the universe colliding with other planets.

Answer 9

the earth would probably freeze soon after

Answer 10

It'd be awful cold, awful quick!
