Space: Inside the Outside That's in Between (Unabridged‪)‬

Of all the things we know about the universe, what do we really know about the nature of space? For example, is there a beyond space? Can space exist in the absence of matter? Though it may seem like a dumb question - 'where' does space come from? This essay takes a look at what some scientists have to say on this issue; the work also contains many references on the topic of spacetime and relativity, which should be useful to physics students.
