38.2 "N 10^80", the Square of 10^40        
"the number of protons located inside (the) Hubble radius (cth), the   distance traveled 
by light since the creation of the Universe, is N   10^80... not much less than the 
total number of baryons (protons and   neutrons), or even the total number of baryons and electrons too.   Note that N is the square of the ubiquitous number 10^40, 
a    remarkable apparent coincidence...
Davies.
38.3 Age of Universe and Number of Particles 
    
Because 10^40 is so unusually large, it is all the more striking to   encounter this 
same number in several apparently different    contexts. It was noted by Sir Arthur 
Eddington and Paul Dirac, that   the age of the Universe should be related numerically to the number   of particles...
Davies.
The magic number 10^40 crops up yet again... (concerning the total   number of charged 
particles in the Universe)...
Davies.
38.4 Background Radiation 
          
(and again) concerning cosmic dynamics of background radiation in   equation <radiation/rs 
 is less than 10^-29> and is close to the value  (10^40)^-3/4.
Davies.
38.5 Change Effects of One Part in 10^40 
      
..."dramatic effects would result from changes in the strength of   gravity, or the 
weak force, of less than one part in 10^40.
38.6 Age of Universe and Ratio of Electric and gravitational Forces 
   
...the age of the Universe (10^40) in nuclear units is the same huge   order of magnitude 
as the ratio of electrical to gravitational forces   between two protons.
Davies.
38.7 t^now(human existence) and t^n(nuclear time) 
       
...the mystery is, why does t^ now (existence of the human    community) bear the 
same numerical relation to t^n (nuclear time)   as the electric force between the 
protons bears to their     gravitational attraction?
Davies.
38.8 Ratio (10^40)^1/4 and the Number of Stars and Galaxies 
     
...or the ratio (10^40)^1/4 of the number of stars in the galaxy and   the number 
of galaxies in the Universe.

38.9 Dr. Harold E. Putoff Answers 
       
The answer to these cosmic coincidences seem to be well explained   by Dr. Harold 
E. Putoff in a paper originally appearing in Speculations  in Science and Technology, 
Vol. 13, No. 4, pp. 247-257, 1990. It also   appears on the internet concerning zero-point fluctuation fields   (zpf) and cold fusion.
Under the heading of the paper "The Energetic Vacuum":
The implications for Energy Research, "subheading source of zero-  point energy", 
Dr. Putoff describes why these coincidences occur:
"The details of the calculations (of the previous paragraph) examine   the possibility 
that zpf fields drive particle motion, and that the   sum of particle motions throughout 
the universe in turn, generates   the zpf fields, in the form of a self-regenerating cosmological   feedback cycle not unlike a cat chasing its own tail. This self-   consistent 
field approach, carried out, assuming inflationary    cosmology, is found to yield 
the correct frequency distribution and   the correct order of magnitude to match the known zpf distribution,   thus supporting the hypothesis that the zpf fields 
are dynamically   generated.
As it turns out, there is an additional bonus from the calculations. A  derived expression 
relating to the zero-point energy density to such   factors as the mass density and 
the size of the universe also yields   a precise expression for an observed "cosmological coincidence"   often discussed in the context of Dirac's large-numbers hypothesis: 
  namely, that the electrical to gravitational force ratio between the   electron 
and proton is equal to the ratio of the Hubble distance to   the size of the classical electron. According to the relevant    calculations such a cosmological coincidence 
is seen to be a    consequence of the cosmologically-based zpf-generation mechanism 
 under consideration that serves to link cosmological and atomic   parameters.
The overall picture that emerges, then, is that the electromagnetic   zpf spectrum 
is generated by the motion of charged particles    throughout the Universe which 
are themselves are undergoing zpf-  induced motion, in a kind of self-regenerating 
grand ground state of   the Universe. In contrast to the other particle-field interactions, 
the  zpf-interaction constitutes a stable "bottom rung" vacuum state   that decays 
no further but reproduces itself on a dynamic-generation  basis. In such terms it 
is possible to explicate on a rational basis   the observed presence of vacuum zero-point 
energy".
