Abstract
This paper suggests that a universal solution to the Fermi paradox exists and can be derived directly from the definition of life and/or intelligence, therefore eliminating the need for any questionable assumptions and even for the anthropic principle. The proposed solution puts an upper limit on the growth of civilizations that is independent of resource availability or biological factors.
