The number 1 only exists as a concept in our universe.
It appears that all particles have polarity. Even down to the smallest quark bar, there is polarity.
It appears that the number one could only exist in a singularity, of which we have never measured. There is no way to dissect a particle and maintain its function, there's no way to separate the polarity and exist.
The only time a singularity may have existed, was at the moment of the big bang.
With the discovery of the Higgs Boson in 2012, we know Black holes are not a point of singularity. They are a medium of Higgs Boson Particles accelerating (gravity) to a force that inhibits an electromagnetic bond.
The number 1 only exist in our universe as a concept - we cannot isolate particles to a singularity without polarity. Multiple quarks/bars make up any single atom/molecule/photon ect... there is no way to isolate a singularity because all known particles are made up of other quarks and bars (there's evidence of smaller objects also, however, those have not been scientifically observed yet).
