A place in the universe

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.
