Definitions

Noun
  1. 1
    The ultimate basis of physical substance, before it has been given form. uncountable

    "Perhaps the last named, mass-energy, comes closest to converying the Aristotelian idea of protomatter as the basic stuff of the universe.

  2. 2
    A hypothetical substance from which the universe is created. uncountable

    "It is possible that the two principal alternative conceptions of the inexhaustibility of the microworld (an infinite "linear" hierarchy of structures or some primordial entity infinite in itself— single "protomatter" or an infinite number of simplest and equally elementary constituents) do not exhaust all approaches that are feasible here."

  3. 3
    An unstable substance that is powerful and dangerous. uncountable

    "The No Damage option occurs when the computers are directed to control the protomatter environment from directly harming the user. This is because MegaCorps prefer their executives alive rather than dead."
