Christianson (an 80 year old veteran of the Korean con¬flict) obtained his engineering de¬gree from Seattle University—a Jesuit school. He re¬tired after a successful aerospace engineering ca¬reer in 1988. He and his wife, "Dodo," now live in Peoria Ari-zona, where he continues to work on a cold-core model for all planetary bodies.Earth sciences piqued his interest, during the heady days of moon walks, when he was chief engineer for the Titan II weapon system. For years he tried unsuccessfully to define an Earth-machine with a hot-core to answer surface observations. However, early models defied consistent definition—all the parts would not mesh. In an attempt to fathom this in-consistency, he set his mind theory free; but, held fast to known physical facts. This shifted his quest to the basic con¬stituents of molecular clouds—wherein stars and planets are known to grow.Article searches led him to the unique physi¬cal characteristics of quantum solid hydrogen, compressed ice and superfluid helium. He blends these characteristics into a working sys-tem's definition of a naturally formed heat pump, whose ex¬pansion and contraction strokes fit well with surface observa¬tionsview less
