how long do you think the life forms on earth will survive when the sun burns out?

Answer 1

ok, assume no supernova.. just suddenly someone turn off the sun.. *pop*

the whole planet would be much below sub-zero temperature.. (maybe -200 degree celcius?).. before we think about growing up foods, we would think about making some heat.. and since no solar energy, no wind energy, no hydro energy (these resources are basically coming from the sun energy).. we might start to use fusion and fission energy, but we might not use fossil fuel or other combustible energy because we will run out of oxygen since all plants can not do photosynthesis and eventually die.. then we need to produce our own oxygen by extracting from water.. then come to producing our own foods..

do you know how human lives in matrix movie? i think that's the way the best description of how we would live without sun.. though i think we can not support the whole earth population..

so, my answer would be.. some few people will survive.. but eventually they might need to transfer to other solar system.. the other life form probably would be extinct

Answer 2

Life on Earth will become extinct "before" the Sun burns out. The actual life-cycle of our Sun will be as follows: First, when the Sun depletes it's hydrogen it will hyper-dilate 100 times its mass into a helium-burning Red Giant star. This catastrophic event will discharge a sudden hyper-radiation burst and flash that will fry everything on the face of the Earth and it will expand to beyond the orbit of the Earth, between the planet Mars and the Earth. The Earth will have to react similar to a billiard ball as the shock wave of the hyper-dilation impounds into the Earth, thus it will be knocked out of its orbital path a re-establish a new orbit further out from the stellar center of our Solar System. It may become a dead planet, having its entire atmosphere and water torn away by the Hyper-Dilation Event.

Eventually, the Sun will deplete its helium and then undergo a Nebula Discontinuity Event, where its outer shell will be expelled in a great explosion of its photosphere, and the tremendous weight of its gravity will cause an internal "crunch" of its mass, compressing its protons into a dense White Dwarf star equal to the mass of the Earth but still retaining the electromagnetic field of a G-2 class main sequence star.

Answer 3

Hmmm...........i think that it will be millions of years before the sun burns out and in that time mankind will have undergone a couple of evolutionary changes by then, after all it has been 3 million years give or take here and there for mankind to evolve into what we are today so in the future when this happens we will most likely have left the cradle of earth and expanded into other solar systems to form other colony's on distant worlds.

Answer 4

If the sun instantly disappears:

Animals along the equator will die within 3 to 4 days, because of coldness.

Animals in the artic and anartica may die off from weeks to a month as they use to darkness and coldness.

There will still be live forms in the deep ocean even the sun dies off.

Human and it's civilization will extinguished in about a month or two as the energy and food supply vanish.

On the other hand, if the sun was naturally dies, it will becomes an white dwarfs and swallow the earth. We will all extincted simultaneously.

Answer 5

Actually, they won't last that long. Before the Sun goes "out", it will expand into a Red Giant, and will fill the present day Solar System to a distance about that of Venus' orbit. It's hard to imagine life existing on Earth in such circumstances.

Answer 6

No. we can all be useless lengthy before that occurs. in truth, the solar probable gained't burn out for yet another 5 billion years or so. thc probabilities of ANY human beings being left in that element is rather a lot 0. NO animal, modern-day or extinct, has lasted that lengthy. As for the solar "burning out". it gained't fairly "burn out". what is going to ensue is that because it loses gasoline, the interior rigidity led to by using the fusion reactions will be unable to keep up its push adverse to the gravitational forces. the solar will give way. this give way will reason a secondary explosion which will smash an excellent type of the photo voltaic equipment, and reason the solar to educate right into a "brown dwarf" (Our solar is only too small to "go nova"). The brown dwarf is only too at risk of help and life as all of us understand it, so NO, the cycle gained't "repeat itself". by using how, a 'technology" isn't a human life time (70-one hundred years), although this is the standard time between delivery and childbearing -- it is about 20-25 years. one hundred years is 4 or 5 generations.

Answer 7

LMAO not very long....but the sun will expand millions of miles outwards before it burns itself out as a red dwarf. It may even swallow up the earth, but it will certainly make the earth uninhabitable unless you lived deep underground. Unless we humans have annilated ourselves by then my guess is that we would have moved to live on other planets outside of our solar system by then and would not have to wait for the sun to die.

Answer 8

They will be gone long before that. Our sun is expected to expand in about 20 billion years in to a red giant until its size is same as the orbit of Mars and then contract into a white dwarf.

Answer 9

before the sun burns out, it will expand to the point where it completely engulfs the earth. there will be no earth at all long before the sun burns out.
but even so, cockroaches might just survive that.

Answer 10

Less than eight minutes if the sun goes supernova or becomes a dwarf star ! Actually, all life will be long gone before that happens.
