I am sorry it didn't work out for you. Please elaborate. I make no claim 
that the number unifies anything. I merely state that it is a number that is the 
 maximum photon frequency possible in this universe. It is a constant built of 
constants: fmax=SquareRoot(c^5/(2*G*h)) where c is the speed of light, G is the 
gravitational constant, and h is the Planck constant. Conversely the minimum 
frequency possible in the universe is simply H or the Hubble parameter. That is 
all.
