Imaginary and Real

" 'Imaginary' and 'Real' turn out to be identical. Consider this chow bench. On one level of abstractions it is mathematical equations. At the level just below that it is swirling nothingness, with mass-energy a rare event. But on the gross level abstracted by my senses I can place this drink on it with utter confidence that it will not sink through this near vacuum."

RA Heinlein, The Number of the Beast.
