What's the difference between outerspace and innerspace?

The terms 'inner space' and 'outer space' are arbitrary. In fact, such terms can apply to any body in the universe, whether it be a planet, a star, a moon, etc. We usually use the term 'outer space' to refer to the black void above Earth's atmosphere where all the other physical bodies in the universe are located. read more
