Additional quotes by Frank J. Tipler
The factors <math>f_lf_if_c</math> should not depend strongly on the evolution of the Galaxy... and so can be regarded as constants. Since the Galaxy is between 11 and 18 billion years old, the number N of stars older than 5.3 billion years is about twice the number of stars formed after the Sun, and thus approximately equal to the number of stars in the Galaxy, 10<sup>11</sup>. Thus <math>p \leqslant 10^{-11}</math>. If we accept the usual values of <math>f_p=0.1</math> to 1 and <math>n_e = 1</math> found in most discussions... then <math>f_lf_if_c \leqslant 10^{-10}</math>. The number of communicating civilizations now existing in our Galaxy is less than or equal to <math>p</math> x (number of stars in galaxy) = 1; that is to say, us.
