Most of the current controversies associated with science revolve around the vastly different reactions people both within the scientific community and outside it have, not to the strange features of the universe that we can observe for ourselves, but rather to those features we cannot observe.
In my own field of physics, theorists hotly debate the possible existence of an underlying mathematical beauty associated with a host of new dimensions that may or may not exist in nature.
School boards, legislatures and evangelists hotly debate the possible existence of an underlying purpose to nature that similarly may or may not exist.
It seems that humans are hard-wired to yearn for new realms well beyond the reach of our senses into which we can escape, if only with our minds. It is possible that we need to rely on such possibilities or the world of our experience would become intolerable.
