It is said of the concept that seeks to find out "what" was before the formation of the current universe in which we find ourselves; It's a booming concept given the questioning of the Big Bang. According to the most physics-related versions, the preuniverse must have been a dark fog of matter and energy, and must have been cold. Matter had to be composed of hydrogen, nitrogen, iron and aluminum, the latter possibly one of the most abundant elements before the formation of our planet earth along with hydrogen and nitrogen. From a more philosophical point of view, there may be an approach that there could not really have been a "before" since perhaps there has never been a beginning, or it is considered to be a whole continuum of an evolutionary type, or one more universe among millions of other possible universes, more along the lines of infinity.
