Is Nature that consistent? I don't believe it is. From our point of view nature looks that way, but probably because our time perspective is so brief, and also because our consciousness makes up for its lack of consistency. Reality as we understand it, isn't the smooth thing we have come to believe it is, even scientist have detected that "reality" happens many milliseconds before we become consciously aware of it. Even the damn speed of light has been clocked at all different speeds! Some speeds have been clocked at 300 times faster the "agreed" speed of light. Nothing is consistent, nothing is constant, it is the mind that makes it look that way. Biology, chemistry, all those science are nothing but ways of describing what really is NOT there, but we want to convince ourselves so badly it is. Cheers!
