| Sumario: | Discusses physics research at the University of New South Wales and elsewhere, which indicates that alpha and other physical constants can change over time. How alpha is calculated, the role of the expanding universe, and the red shift; Mention of string theory, or M-theory, that might allow constants to vary over time; Possibility that a changing alpha might come from an unknown force of nature that could modify the law of gravity; Criticism that the new measurement disagrees with a different way of determining alpha in the remote past. |
