ABSTRACT
Ageing is defined by physicists as entropy. The second law of thermodynamics, in simple terms, dictates that all things move from order to lesser order. This is moving from low entropy to high entropy. In principle, without any external influence, any system, material or physical relationship will break down and, if given long enough, will revert back to the atomic building blocks that created it in the early days of the universe. On an astrophysics level, there is considerable debate as to how far this process could go and the potential effect on the universe as we know it. That is many billions of years into the future, a long way removed from the practical considerations of life as we know it. However, what we experience and attempt to control is governed by this principle.
