Early astronomers such as Ptolemy taught that the stars were
fixed in the heavens and revolved around us. Today to our dismay
we know that we live in a violent and uncaring universe that will
continue to expand beyond the reach of our instruments. We are not
in the center nor is anything fixed in place.
We will always ponder our place in the universe because
understanding of infinity is not biological or genetic; our
experiences do not teach it; our senses do not reach it.
