Robert V. Gentry

In his early career, Robert Gentry served as a physicist (B.S., M.S.; University of Florida) in the nuclear/space defense industries and taught college/university math and physics. He then developed an absorbing interest in testing the conventional evolutionary model of Earth’s origin and age, and has dedicated his scientific career to finding answers that could only be obtained through years of investigating fossil traces of an extraordinary type of radioactivity inscribed in Earth’s basement rocks, the granites.
