Mysteries of Physics
I just read We Have No Idea by Jorge Cham and Daniel Whiteson, a book about all the things we don’t know about the physical universe. These include: dark matter, dark energy, the basic elements of matter, the nature of mass, why gravity is so different from other forces, the nature of space and time, how many dimensions there are, why light has the speed it has, the origin of cosmic rays, the puzzles of anti-matter, what happened before and during the big bang, whether there can a theory of everything, how big the universe is. It appears that physics is rife with mystery. I wrote to one of the authors, Professor Whiteson, and asked if he knew about the work of philosophers and others on the mysteries of mind, notably Chomsky and McGinn. He replied that he did but admitted he didn’t know much philosophy. It seems to me that this is a welcome convergence for the mysterians among us: evidently matter is as mysterious as mind. True, the authors fight shy of declaring irresoluble mystery, but they clearly accept that some mysteries of physics look pretty formidable—especially where dark matter and dark energy are concerned. (This made me wonder if Dark Materialism might be true of consciousness, i.e. the mind is material but the matter involved is of the dark variety; but this is not a theory just a wild speculation.) Most authors who write popular physics books seek to wow us with how much physicists know; this one refreshingly owns up to the depth of our ignorance. I recommend it: it’s probably the best popular physics book I’ve ever read.
