What would happen if we don't have sun for 3 days

I heard the in wont shoe for 3 days supposedly according to NASA

You should read the ACTUAL NASA site and look this stuff up. NASA has already said this was false. And the comet passed on Oct. 16th, 2012. Do you notice anything? I didn't.
Perhaps because nothing happened.

If we didn't have the sun for three days, we would all be screwed for sure. Since the sun is the leading cause for all of our energy, we wouldn't be able to do anything literally. On top of that the sun is responsible for almost all of the heat on the planet, therefore we would freeze up and die from severe cold conditions.

You heard a hoax.
The "according to NASA" is just part of that hoax - NASA never said any such thing (especially since its not even possible).

Its really a shame people don't learn any science in school and aren't even willing to research a story before believing it.

Does the sun shoe now?? How many shoes does it have? And what does it do with these shoes?

There is a town in finland that doesn't have a sunrise from November to January. look it up.

The in wont shoe ????

What happens at night time?
