Tegmark takes a mathematical approach without being too mathematical. He posits the notion that earth supports conscious life, which is a mathematics aware that it is information emergent from mathematics. Its as if consciousness is an equation with both sides mathematically defined in such a way that exchanges between sides cannot go unnoticed. Whenever information passes from one side of the equation to another, the result is instantaneous self awareness in order for the mathematical structures to reconcile and be in balance. Consciousness is the eternal imbalance of two sides of a set of equations containing 32 fixed parameters, but simply capable of nonlinear adjustment. The sets of equations, Tegmark describes by their various degrees of universality of information. Being permanently in disequilibrium, we have the driving force of consciousness at many levels and subject to many different systems ...
