Science: Thomas Gold
found clouds of them drifting around in space. Thomas' discovery of oil and bacteria at great depths below igneous rocks in Sweden I would think clinched it. A German author whose book I was reading suggested that the natural nuclear reactor discovered by the French in Gabon, W. Africa in 1972, might not have been totally natural in origin. So I asked my friend Stephen Thomas, a nuclear physicist, about it. He referred me to a web site which said that the 1.7 billion-year-old deposits contained 'organic' matter, which at that age cannot have been of biogenic origin.
