Why (on space)

Why is there so little matter,and so much space in the macro realm" Why is this worse in quantum realm? BHs have little space. Do they have any space for atoms? Can the electrons wobble inside a BH? Do they spin in place? How close can BH gravity compress quarks? Can they touch? Can BHs hold a charge? If the Earth was compressed to a pea,and could reach a speed of99.999999999 of c would its mass density become 70,000 times greater? Would it have reached its critical mass and imploded? Reality is my thinking its mass density at that speed would be closer to 70 trillion time its rest weight. TreBert
