There is no smallest.
Atoms are galaxies.
As above, so below.
Matter never implodes to a Black Hole,
Black Holes explode matter.
The Universe is Everywhere and Everywhen.
Curvature of Space produces matter, which
thereafter radiates the energy away in
an attempt to ‘straighten’ the Space.
But if the curvature is a loop, that never
happens. Radiation is one type of loop.
Matter is another.
