Black Holes are a predictable Binary Dimension Theory construct.
They are, however, not black, and not holes.
Being fractals, they are of the same geometry as basic units of dimension. The distal ends are connected together. Brain bender, indeed.
If our sensors would indulge, we would classify BH’s as the brightest things in the observable universe.
Almost everything in dimensioned space lives in a black hole, or in one of the equally predictable fractal constructs that are the fabric of a Black Hole.
Black Holes are fractals, and would appear to be rare, but they are not rare at all. They can be defined by a mathematical limit, a boundary condition which divides The Dimensioned from the Undimensioned.
In short, they are very, very, large Higgs Gates.
Black Holes are sinks for quantized dimension (matter), and sources of raw dimension, which means that Black Holes are simultaneously White Holes.
Black Holes, are the norm, our backwater Solar System is the aberrant.
Enjoy your swim. You are being bathed in Dimension that came from, you guessed it, Black/White Holes.
