EXTRATERRESTRIAL LIFE.

(In honor to the efforts -in this regard- made by Giordano Bruno, RIP)
Xuna's Formula for population estimation.

(Note: Some of the math symbols do not print properly on Facebook. Please, look at the scan of the formulas on the mosaic posted for better detail).

N _X  = N ₀ . P_i=0 (F _i);

P_i=0 (10^-11);

·       N _X  = Planets with intelligent life (Xuna´s Population Estimate).

·       N ₀ = Initial number of stellar objects

·       P_i=0 = Product of reduction factors from i=0 to 10

·       F _i= Reduction factors (powers of 10)¸ F _i= 10 ^{e i} 

·       e _i  = exponents of the powers of 10

·       Evolutionary stages =  ( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

·       Vector of exponents = ( 0, 1, -1, -1, -3, -1, -1, -1, -1, -2, -1)

Log(N _X  )= Log( N ₀ )+ S_i=0 (e _i);

S_i=0 (e _i) = -11

Therefore, applying antilogarithms …

N _X  = N ₀ . (10^-11);
