Homework Help: Fermi paradox solution

  1. Mar 25, 2016 #1
    1. The problem statement, all variables and given/known data

    In the book "In searcg of life in the Universe" A.D. Ursula gave the following formula

    R1/C1 = R2/C2 (A)

    when the contact between two civilizations happens, where R - result from a contact and C - cost to make a contact for those civilizations.

    2. Relevant equations

    The key equation is

    R1/C1 = R2/C2

    3. The attempt at a solution

    Let R1 and C1 be result and cost for Earth.

    There is great silence because

    R1/C1 < R2/C2 (B)

    If it were otherwise it would mean that the contact already happened but there is a great silence.

    Hence equation (B) is fulfilled.

    Was there a question?

    Obviously the equation is of little use, we
    don't learn the value of R until after we've spent C ( and even C is subject to change).

    R could be absolute utopia or total destruction. But I, for one, am interested in finding out :smile:
