What would happen to Earth if there were no light?

Answer 1

Earth Without LightPresuming the question is about what happens if the sun, our principal source of light, suddenly disappeared, what follows is a scientifically credible answer:

Without sunlight, plants die, then animals die.

Without sunlight earth's atmosphere cools.

Note that the Earth does not immediately freeze. The Earth's interior contains many radioactive elements and as they decay the heat released will keep the interior warm for a long time to come. The surface, however, will rapidly radiate heat into space, and fall to the temperature of the solar system's outer planets.

Earth's oceans contain considerable latent heat, these would require months or years to freeze solid. The ocean surfaces would begin freezing from the poles towards the equator within a matter of weeks.

Grass and trees would begin dying within days. Pine trees would last among the longest as these can remain buried beneath ice for months at a time. Water would precipitate out of the atmosphere, making the air very dry and cold.

If the sun went missing altogether, which is the source of gravity holding the solar system together, the planets, including Earth would fly off in straight lines until ultimately interacting with some other massive body millions of years hence.

Answer 2

If you mean the light of the sun, all life on earth would end. The sun is the engine that drives our planet. No light - no photosynthesis. All vegetation dies. Further, if there's no light, there's no warmth. The planet freezes over, and the planet dies.

Answer 3

The Earth would freeze solid without the Sun's warmth.

Answer 4

Complete and utter darkness, like darkness you've never experienced in your life.

Answer 5

we would die

Answer 6

Nobody would be able to see.
