Now, a new proposed law of physics that describes the geometry of physical reality on the cosmological scale might help answer some of these questions. Plus, the new law could give some clues about the role of gravity in quantum physics, possibly pointing the way to a unified theory of physics. http://www.physorg.com/news169725980.html Physics Mon, 17 Aug 2009 11:07:00 EST news169725980 (PhysOrg.com) -- Although it may seem like gravity is the same everywhere on the Earth, it actually varies a small amount from place to place.
