Does this new hypothesis cover as much of the observed data as the
old one? It doesn't seem to. So why consider it as possibly better
or equal? To answer your question all hypothesis need to meet such
criteria. If science is working well the established hypotheses have
already met such criteria in the context of then existing knowledge
and observations. But all are required to meet the same burdens of

cover at minimum the existing covered observation as well and have at
