"On NPR's Science Friday, an astrophysicist proudly asserts that scientists now have a 'simple, well-defined model that explains everything in the universe'--or at least the 5 percent of it that can be described as 'familiar matter.' 'Dark matter' and 'dark energy,' whose properties scientists barely understand, make up the rest. The show's host is incredulous. 'Aren't we in the twenty-first century?' he asks. 'To say we don't know what makes up 95 percent of the universe is astounding.'"
Safransky goes on to say that he found reassurance in these numbers because in spite of years of therapy and spiritual studies, 95 percent of his own existence remains an utter mystery.
