Axions, the Anthropic Principle, and the Tilted Universe*

The axion is a light, weakly interacting particle that is a
consequence of the Peccei-Quinn solution to the strong CP
problem, proposed in the late 1970's. The story of the axion is
like A Thousand and One Nights, digressing its way throughout
particle physics, astrophysics and cosmology. I discuss this
story, including more recent developments, and explain how one
might detect the presence of an axion cosmic string ten trillion
light years away -- a million times farther away from Earth than
our present horizon.
