You're right, I mixed it up with the complex numbers being isomorphic to R^2. Thanks for clearing it up!
Love btw how I get downvoted for an honest mistake.
Is this some joke I'm not getting? Cause yes, real numbers are the closure of irrational numbers, but imaginary numbers are just isomorphic to them.
Just to add some formality to this, the original commenter might want to look up the shell theorem for classical mechanics and Birkhoff's theorem for general relativity.
Also, desolate sounds a lot more negative than empty to me. Maybe something like "devoid of [...]" might convey more of a similar idea?
Actually a good point, tho. And also a good thought: If there is no special direction, what would be up? And that's where quantum mechanics gets even weirder: It's either up or down in the direction you measure.
