The first phase of The Nexus Theory (TNT) is “reaction.” For any configuration of matter to possess the capacity for change, logic requires that it first be able to react to its surroundings. This is the most basic requirement of all nexuses. And, given the logic that apparently governs our Universe, all matter everywhere possesses this basic capacity.
Additionally, the ability to react itself gives a nexus an inherent identity distinct from its surroundings; a nexus that can react to matter other than itself is fundamentally different from that matter. This idea is useful because it means every nexus in the Universe can be distinguished from every other nexus by its reaction.
Evidence
Elementary Particles
Within the standard model of particle physics, it’s estimated that the first elementary particles of matter (the first distinguishable nexuses) condensed from their unified precursors within a tiny fraction of time after the Big Bang. These were the first reactions we know of. At this time, the primordial entropy in the Universe was at an all time low, meaning the potential for work to be done was at its highest.
These basic elementary particles represent the beginning of matter’s journey into consciousness.
