Could life on earth continue to exist with if there were no sun?

Question

Great answers and by life, I mean any and all life.. not just humans.

Answer 1

There are actually entire ecosystems around deep ocean thermal vents that do not ultimately get their energy from the sun. The most evolved members include crabs. They do, however, require liquid water and oxygen, except perhaps for the bacteria in the vents themselves. After a few thousands, the oceans would freeze solid, except around the hot vents themselves, and there would be no source of oxygen. Oxygen comes from photosynthesis, which requires sunlight. We're left then with only bacteria.

Answer 2

Not human life, or most other life for that matter. There is possibility for some bacteria and/or viruses to live deep in the earth, but nothing on the surface would survive.

Answer 3

Any life not dependent on sunlight, like the tube worms at the 'smokers' at the bottom of the ocean could keep on living, until the heat received from the center of the earth drops too low.

Answer 4

No, the Earth would freeze if the sun was to for some reason stop existing. But if the Sun was to explode, it would engulf all of the "inner planets" ie the ones inside of the asteroid belt. I doubt any creatures could exist except for certain microbes and bacterium.

Answer 5

Plants would die, hence all land creatures would eventually decease. However, what is interesting is that many sea animals might actually survive assuming they can withstand the extreme cold that follows. Of course, if the sea were to completely freeze over...that chance would be minimized.

On another note, the sun keeps us in an orbit. Without it....perhaps we would be flying through space...destined to impact another solar body and destroy us entirely.

Answer 6

Aside from the extreme cold, with the absence of light, no photosynthesis would eventually deplete the atmosphere of oxygen....that would make a little thing we like to call breathing pretty tough. The sun holds all of the planets in our solar system in orbit with its gravitational pull. If the sun disappears, all planets would be set off on random tangential trajectories. Perhaps the smaller planets and moons would be drawn to Jupiter.

Answer 7

No i think of people cant exist w/o the sunlight by way of fact the sunlight is needed to make the flaws we consume i.e flowers and animals want the flowers to stay nicely the omnivores, manmade easy can basically flow to date ,it can not easy the finished international and it may be quite chilly w/o the sunlight BRRRRRRRRRRRRRRRRRRRR! we could desire to die of the chilly climate and stuff anyhow the sunlight wont flow away it is going to arise till Judgement Day so do no longer hardship

Answer 8

No, except for maybe some specialized bacteria that exist near underwater volcanic vents. Everything else is dependent on chlorophyll

Answer 9

Might get a little chilly. Oceans would freeze, no photosynthesis so plant life would stop..........I'm guessing that the answer is no.

Answer 10

The temp of earth would drop to –459.67 °F on the Fahrenheit scale
