Fine-Structure Constant Maybe Not So Constant

Kilrah_il writes "The fine-structure constant, a coupling constant characterizing the strength of the electromagnetic interaction, has been measured lately by scientists from the University of New South Wales in Sydney, Australia and has been found to change slightly in light sent from quasars in galaxies as far back as 12 billion years ago. Although the results look promising, caution is advised: 'This would be sensational if it were real, but I'm still not completely convinced that it's not simply systematic errors' in the data, comments cosmologist Max Tegmark of MIT. Craig Hogan of the University of Chicago and the Fermi National Accelerator Laboratory in Batavia, Ill., acknowledges that 'it's a competent team and a thorough analysis.' But because the work has such profound implications for physics and requires such a high level of precision measurements, 'it needs more proof before we'll believe it.'"

    we need more research to tell if this is first or not.

      I am unable to reproduce your results.

    The fine structure constant is given as being equal to "e^2/hc", so if the FSC is not a constant then one (or more) of the other values must also be a variable.

    Or maybe the "2" is changing?

    Not mathematically, but 1.999--> 2.001 or such.

    They seem to be in good shape. Thank you for your efforts.
