Explanation:
Welcome to
millennium
three.
During
millennium two,
humanity continually redefined its concept of "Universe":
first as spheres centered on the
Earth, in mid-millennium as the
Solar System, a few centuries ago as the
Galaxy, and within the last century as the
matter emanating from the
Big Bang.
During
millennium three humanity may hope to discover
alien life, to understand the
geometry and composition of our present concept of Universe,
and even to
travel through this Universe.
Whatever our
accomplishments, humanity will surely find
adventure and
discovery in the
space above and beyond, and possibly define the
surrounding Universe
in ways and colors we cannot yet imagine by the threshold of
millennium four.
