Fermi Paradox
Each one of the main novels deals with a possible resolution to the Fermi Paradox. The first, Time, is set in a universe that is completely devoid of intelligent life beyond that of mankind and its creations (i.e. A.I. and uplifted animals).
The second in the series, Space, proposes the opposite: that life is endemic to the universe, and there is intelligence in nearly all possible places of the cosmos. The solution to the Fermi Paradox in this novel is that intelligent life is continually wiped out by cosmic disasters before it has time to spread too far.
The third novel, Origin, is set in a multiverse that is a compromise between the ideals in the first two novels: that life is only on Earth, but at the same time is everywhere. This novel solves the Fermi Paradox by suggesting that intelligent life is segregated into separate parallel universes.

Famous quotes containing the word paradox:
“The conclusion suggested by these arguments might be called the paradox of theorizing. It asserts that if the terms and the general principles of a scientific theory serve their purpose, i. e., if they establish the definite connections among observable phenomena, then they can be dispensed with since any chain of laws and interpretive statements establishing such a connection should then be replaceable by a law which directly links observational antecedents to observational consequents.”
—C.G. (Carl Gustav)
