Physics and Feng Shui
Just saw this on FB, although the report apparently came out last year: "Physicists confirmed that clocks in two rooms at identical heights separated by only 10 meters horizontally run at measurably different speeds — not because of gravity differences but because local mass distribution differences create subtly different spacetime curvatures detectable by modern optical atomic clocks. "Researchers at the University of Colorado Boulder placed optical atomic clocks in adjacent laboratories on the same floor and measured tick rate differences for 6 months. The clocks diverged at 10 to the power of minus 21 seconds per second — caused by slightly different gravitational potential created by different wall thickness, equipment mass, and geological substrate beneath each room. "The measurement proves Einstein's general relativity operates measurably at human spatial scales, not just between planets." I assume when they say, "not because of gravity diffe...
