WSOGMM sends in an arXiv blog post about reflecting gravity waves
. The speculation is that reflected gravity could go some ways toward explaining the odd readings being returned by Gravity Probe B
. "In the couple of weeks since he introduced the idea that superconducting sheets can reflect gravity waves, Raymond Chiao from the University of California, Merced, has been busy with a couple of buddies working out how big this effect is... Chiao and co. ask how big the effect of a gravitational wave on a thin superconducting sheet is compared to the effect on an ordinary conducting sheet. The answer? 42 orders of magnitude bigger."
