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.
Big Bang theory could be debunked by Large Hadron Collider. Scientists at Cern could prove the controversial theory of ârainbow gravityâ which suggests that the universe stretches back into time infinitely, with no Big Bang.
