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.
As written in the citation, This unexpected discovery, offering strong evidence that the universe began with the Big Bang, ushered in experimental cosmology.. Penzias and Wilson shared the Nobel Prize in Physics in 1978 in honor of their findings. The CMB is noise leftover from the creation of the Universe.
