IUPAC definition. polymerization: The process of converting a monomer or a mixture of monomers into a polymer. An example of alkene polymerization, in which each styrene monomer's double bond reforms as a single bond plus a bond to another styrene monomer.
There is evidence to indicate the Big Bang may have resulted from another, earlier universe collapsing in on itself, rather than from expanding from a point on infinitely hot and dense material. Instead, the universe appears to be going through constant phases of expansion (as it is at present) and contraction in a never-ending cycle. This theory of universe formation, known as the Big Bounce, was first proposed almost a century ago.
The beginning of the universe, the start of space, and even the initial start of time itself. Nothing we observe today existed prior to that exact moment. Further, it was something outside of time, outside of space, and outside of matter that caused all of this to come into existence.The realization that our universe started, and did not always exist, brings enormous challenges to nontheistic scientists.n this point of origin, all the mass in the universe was compressed into a single point of infinite density...smaller than a single atom. 2 Then in a cosmic explosion--the Big Bang--the universe came into being.
