Fine-Structure Constant is Still Constant

Scientists continue to provide evidence supporting a central assertion of RTB’s cosmic creation model—namely that the laws of physics remain constant. Using a unique property of the element dysprosium, a team of physicists from Berkeley, California, and Los Alamos, New Mexico, searched for variations over time of the fine-structure constant (which determines the strength of the electromagnetic force). Tests based on two different configurations of the element showed that any variation must be less than one part in a million billion during a year. This negative result matches previous tests demonstrating the constancy of the laws of physics, in accord with RTB’s creation model.
