What is space on the grand scale?
space on the grand scale is known as that which holds the universe and sequentially the galaxy, the solar system,, the planet, the molecule, the atom, the proton, the quark, and so on and so forth.
What is the one thing they all have in common?
that one thing is they are all substantially empty and so can be compacted infinitely, and at the same time retain mass, (and at the reference point of that which is compacted) size, distance, and collinearity, betweenness and angle measure (by the laws of geometry)
therefor with those assumptions if we observe the black hole with its phenomenal mass in an infinitely small space. could it not then be assumed that its a black hole is a universe or rather the inverse of a universe.
