Can Superconductors Block Gravitational Fields?

Posted by chrisd on from the lose-weight-fast-with-no-dieting dept.

jswitte writes "Raymond Chiao, of the University of California at Berkel, believes that superconductors can convert electromagnetic radiation into gravitational radiation. His full paper can be found here. His theory is based on the idea that superconductors might be able to block the so-called 'gravitomagnetic' field just as they block the electomagnetic field in the famous Meissner effect allowing superconductors to levitate in magnetic fields. He claims that when he 'adds the gravitomagnetic field to the standard quantum equations for superconductivity, he confirms not only the gravitational Meissner-like effect but also a coupling between the two breeds of magnetic field. An ordinary magnetic field sets electrons in motion near the surface of a superconductor. Those electrons carry mass, and so their motion generates a gravitomagnetic field.'"

    (Great sig you have - what does it really say?)

    See Occams Razor (the original statement, much abused since), which was roughly "Don't multiply entities beyond necessity."

    To me, that translates to deprecate imaginary dimensions in quantum mechanics, beyond necessity. Necessary means observable.

    To me, superstring theory is just too fantasical to stand. Sorry, Hawking, et al. I don't buy it, the Universe doesn't work like that.

    I think we ought to demote most of the physicists in academia to teaching positions - no "research" for about 5 years or so. Then let students loose on the issues, but with none of that former apprenticeship culture that has held back several generations of scientists.
