There are trillions of stars like the Sun in our universe so "why is it space is dark and cool?" Well I really meant that our stars, giant balls of gases which exist by expelling huge amount of energy in the form of heat and light. So my questions:
Why space is cool even though there are stars like sun in our space that expels huge amount of heat energy?
Why space is dark even though there are stars like sun in our space giving huge of bright light? where does these energy goes? well I meant i.e for example take the planet earth the one side of the which faces the sun is bright and hotter than the earth but another is the opposite so my question is even though there are so many stars in our universe why the space is like the side of the earth that does not faces the sun?
