first science

the missing science, the theory of everything, and the arrow of time

Whilst the mathematical laws of nature do not contain an Arrow of Time, it may be possible to deduce by analogy the Arrow of Time from the cornerstone of First Science, the unifying principle "laws of nature exist".

The unifying principle represents the master symmetry of nature, since the laws of nature remain unchanged for all changes in the knowable universe.  The corresponding master conservation law is postulated to be "conservation of the universe," where the conserved quantity is one universe.  If the master symmetry and master conservation law correspond to each other then, according to generalizations of Noether's theorem, the master symmetry must not be time reversible.  That is, the laws of nature must not be time reversible.  In other words, there must exist a Master Arrow of Time.

Now we see that from the single unifying principle "laws of nature exist," it is possible to deduce features of both the Theory of Everything and the Master Arrow of Time:

The Master Arrow of Time is the source of the many directions of time observed in nature, including the causal, cosmological, radioactive, electromagnetic, aging and thermodynamic arrows of time.  Moreover, the Master Arrow of Time is the source of evolution in all the sciences and, as a result, has widespread implications for all of science, including the evolution of complexity (see book).
