Take a square with sides of exactly one yard. Take a yardstick and measure it- it appears to be exactly a yard. Now, measure it to the nearest quadrillionth of a yard. Will it still appear to be exactly one yard? Not likely. The reality, is that you can measure the sides of a square in increasingly smaller increments on to infinity, and you will eventually find, no matter what, that the sides of the square deviate from a perfect yard at some point. This is because infinity is the only perfect number that occurs in nature. Infinite time and infinite space are truly the foundation for all physics as we understand it, and the only perfect concept that occurs in nature. Nothing is perfect, everything is perfect.
