Ylem is a term which was used by George Gamow, Ralph Alpher and their associates in the late 1940's for a hypothetical original substance or condensed state of matter, which became subatomic particles and elements as we understand them today. It reportedly comes from an obsolete Middle English philosophical word that Gamow came across while thumbing through a dictionary, which means something along the lines of "primordial substance from which all matter is formed", and derives from the Greek hylem, "matter". Restated, the Ylem is what "thing" Gamow, et al, presumed to exist immediately after the Big Bang. Along with the ylem, there were assumed to be a large number of high-energy photons present, which we would still observe today as the cosmic microwave background radiation.

In cosmology, the cosmic microwave background radiation (most often abbreviated CMB but occasionally CMBR, CBR or MBR, also referred as relic radiation) is a form of electromagnetic radiation discovered in 1965 that fills the entire universe. ...
The origin and purpose of ylem is unknown, but it is used extensively by nearbaselines and transapients as a self-replicating building material, particularly in high-energy environments.
A given piece of ylem cannot more than double its mass in less than one microsecond (this means that a given square metre of ylem can absorb and convert power in the zettawatt range: up to 9 times 10 to the 19th watts).
In the event that ylem is placed in an environment where it is receiving energy but has no room to grow, (that is, it is encased in a solid) the ylem will increase in density to approximately three times its normal value and then cease to function.
Ylem is a term which was used by George Gamow and his associates for a hypothetical original substance or condensed state of matter, which became subatomic particles and elements as we understand them today.
The Big Bang theory currently assumes that the universe in which we exist began from a "singularity" (a near-dimensionless point) that somehow came about and exploded, converting into the first subatomic particles and lighter elements (hydrogen and helium, possibly some lithium).
In distinction from a singularity, the Ylem had finite size, with mass equal to the whole of the present universe.
