Space is nothing more than the way sentient humans perceive the structures of mass and energy. It is on a macro level equivalent to the gaps between quantum particles within an atom; and it’s known those ‘particles’ are actually waves. People are locked into perceptions of mass/energy/space because of their own composition existing within known and unknown fields.
The host of the fields is unknown, though I prefer to say ‘God’.
