eli5: Why isn’t outer space hot (or at least not freezing)?

2.64K views

The sun warms up our planet but space is cold. If I lit a candle and stood 20 feet away, I could see the light but not feel the warmth. So, why do we feel warmth from the sun but space isn’t warmed by it?

Space is empty.
So very, very empty.
One star you see in the sky, might just be the light of an entire galaxy.
Space is unfathomably big.

Because entropy is a thing that exists
There will never be enough energy to heat up the universe.
At Noon on Mars, it can reach only as high as 20 degrees, or 70ish f, and mars aint all that far from the sun compared to the other planets, and then there is the fact that there is usually a light year or two between each star, and there between there is nothing to collect or store it.
