'Just as a fish may be barely aware of the medium in which it lives and swims, so the microstructure of empty space could be far too complex for unaided human brains.’

Just like a fish is unable to understand the chemical elements etc... that make up water, maybe us humans might not be smart enough to grasp the full scope of the universe we live in, and never grasp the full extent of what the big bang was or what are parallel universes.
