If you believe William Tifft’s data, there are problems with the modern cosmos. For instance, maybe--repeat, maybe--it isn’t expanding.
William Tifft is 61 years old, has white hair, a decidedly unflamboyant style of talking, and no obvious penchant for self-promotion. His every outward manifestation, from the neat trim of his mustache to the sharp slant of his small handwriting, bespeaks a meticulous, methodical manner. He is devoted to his data.
