Math is modeling. It is map, not territory.

Epicycles were brilliant math, as a model of our view of the cosmos, but the crystalline spheres were lousy physics, as physical explanation.

The idea of string theory seems a continuation of the basic premise of atomism, through quanta, that there is some physical entity at the core of reality, some finite little bit of matter.

Here is another way to think about it;

As mobile organisms, this sentient interface our body has with its situation functions as a sequence of perceptions, in order to navigate, so our sense of time is as the present moving past to future, codified as measures of duration.

The evident reality is that activity and the resulting change turns future to past. Tomorrow becomes yesterday, because the earth turns.

There is no dimension of time, because the past is consumed by the present, to inform and drive it. Causality and conservation of energy. Cause becomes effect.

Energy is "conserved," because it manifests this presence, creating time, temperature, pressure, color, sound. Frequencies and amplitudes, rates and degrees.

So the energy goes past to future, because the patterns generated come and go, future to past.

Energy drives the wave, the fluctuations rise and fall. No tiny strings necessary.

The problem goes all the way back to atomism.

As for Big Bang Theory, if space actually expanded, the speed of light would have to increase proportionally, in order to remain CONSTANT!!

It fails on its own basic premises.
