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.
Some scientists believed that if our universe was created by a singularity, there would have to be a background heat still in existence in the universe. To understand why a scientist would think there is still heat from the big bang you have to know that the universe is still expanding.n other words, the big bang was the beginning of everything. The big bang theory is not the only model that tries to explain the origins of our universe. There are several other theories, but the big bang is the most popular and well known. Here is a link the the NASA page about the big bang theory.
