Weyl's gravity is renormalizable, and Mannheim argues that this should be the starting point for anyĮntanglement Wins - Posted Tuesday Octorber 4 2022įormer pro NFL player Herschel Walker is running for Georgia's Republican seat in the U.S. Gravity first proposed one hundred years ago by the German mathematical physicist Hermann Weyl. To get around this, the author uses a form of quadratic However, it has long been known that classical Einsteinian gravity is non-renormalizable and therfore unsuitable for quantization. The author (Philip Mannheim) splits Einstein's field equations into a classical gravity portion and the associated matter field, which is assumed to be quantum in nature. New paper arguing that not only does gravity "know about" quantum mechanics, but that any attempt to quantize gravity must beīased on the quantum aspect of the gravitational force.
That was pretty neat, since quantum mechanics and gravity aren't normally seen working together. All I could recall about the paper was that it showed how the phase shift is depended on both Planck's constant \(\hbar\) and the gravitational field \(g\) of Earth. Paper from long ago about how a neutron-beam interferometer demonstrated the effects of
With the possible exception of solving the dark matter problem, finding a workable theory of quantum gravity is the number one problem in physics today.
