Nature's laws may vary across the Universe http://www.physorg.com/news/2011-10-nature-laws-vary-universe.html
---- I have arrived at the opinion that the set of axioms known as the "laws of nature" need only apply to our measuring instruments. Our instruments should work according to such axioms, otherwise they would provide us with unreliable measurements. We design the "laws of nature" into our instruments, but the "laws of nature" need not supply us with a framework for explaining all that transpires in the universe. Harry
