I have thought, where does heat come from? The main thing that provides heat on earth is the Sun, chemical and physical activities within the planet also generate heat, but the absolute main source is the sun.
If the sun ceased to exist, if it one day just dissapeared, would the entire earth freeze over? If it would, does that mean that cold is the natural temperature of the empty universe?
If things are cold without the sun, or stars, or other astral bodies radiating heat, does that mean the universe in itself *is* cold?
