It is part of human nature to speculate... at least for some.
Others treat hypothetical metaphysics and physics much as Dr. Johnson (of dictionary fame) did when it was suggested to him that Bishop Berkley's 'immaterialism' might be true... and Johnson 'refuted' it by kicking a stone.
   Some folks simply can't relate to abstract concepts unless they involve 'God'... and they really only do that to cover their bets.

But, as Richard P. Feynman said about his complex concepts..." If I could explain it to the average person, I wouldn't have been worth the Nobel Prize."
