The Cube of Classical Electron Diameter is Related to the Mass of the Observable Universe. The Derived Volume = Entropy of the Observable Universe. ΛCDM Problems. Black Hole Electron Related to the Mass of the Observable Universe.

A cubic volume derived from the diameter of a classical electron would fit in 9.2280 × 10⁵³ kg of matter at Planck density, which is well inside the total mass of the observable universe as given by Planck18. The entropy of the particle horizon is very close to the number of these volumes contained within the observable universe. The number of these volumes inside a Hubble volume is very close to the cube root of the direct product of all the 26 sporadic groups. A ring around the observable universe made out of "black hole electrons" would weigh 9.31 × 10⁵³ kg , which is inside the mass of the observable universe as given by Planck18.
