I love triple points. I once saw a graph of the complicated
  nature of various "fracture" points of water (I think of it as
  "reality as we know it fracturing... 'cause our definitions of
  things are primitive compared to how they will be in the future]
  - and there's many points of convergence, each with different
  properties. Maybe it was hydrogen.. but I _think_ it was water.

  The crystalline structure does different things in different
  temperatures and pressure... and I had/have some ridiculously
  elaborate theory regarding "all matter is really the same"
  involving hydrogen's properties at super-low temperatures... but
  then I realized it was a rabbit hole I needed to get out of
  _fast_ before I became too devoutly attached.

  The changes of crystalline structure _may_ hold a key to how
  matter of one "type" becomes matter of another type, NOT by its
  electron configurations or weights or whatever.. but rather by
  its crystalline STRUCTURE. Like keys in a lock, or the way that
  virii mimic... ok ok.. I'm going down the rabbit hole.. Gotta
  come back up. Gotta come back up. Ok. Ok. It's not my dept. It's
  not my dept. It's not my dept. Ok, there. I'm better now.
