Because about 50% of people here in Physics Forum (including even some mentors) don't understand origin of math and keep parroting that math is human descriptive construct (see results of poll), I found educational to point to theory which could unearth deepest layer of reality: http://www.sciam.com/article.cfm?articleID=0007E95C-9597-1DC9-AF71809EC588EEDF&pageNumber=1&catID=2 According to this math (which is the only one to unite GR with QM), not only all matter around us, but space and time themselves are just products of math (of geometry, to be more accurate). This theory deals with metricless objects (Penrose spinors) and quantizying them obtains space and time, gravity and matter. So, Mentat - what do you say now? Just acknowledge that the hurdles you posted about mathematics were a result of your layman misunderstanding of mathematics and of its origin. Laymann "logic" is useless in understanding nature. Math is the key.
