In terminology, immortality, from in- (not) + -mortal (death) + -ity (quality; state; degree), refers to the study of someone or something being exempt from the arrival of Mor, the Greco-Roman goddess of death (reaction end); in a modern sense, the study of the premise that the forces (or bosons) that move a person, or the energy or matter (or fermions) that embodies the summation of the states of existences of a person, are indestructible, conserved, and or eternal, according to the conservation laws of science, in respect to the movement, dynamics, operation, and or workings of the universe, in some systematic, non-chaotic or non-random way.

Overview
The theory of "eternal-life" (or afterlife), in defunct colloquial speak (see: defunct theory of life; life does not exist), or continued perpetual existence, is an often-discussed and sometimes heated topic over the nature of morality, death, and human existence; generally centered around the nature of the existence or not of the soul, as originated in Ra theology, or moral weight of an individual, in the context of the conservation of energy or force.

In 1843, Ludwig Colding derived a conservation of energy theory on the logic of the immortaility of the soul.

The 1874-1878 Tyndall-Stewart-Tait debate on the relationship between religion and science is centered to a large part on the issue of death, the soul, and immortality.

In 1876, artist William Harnett painting the following work titled "Mortality and Immortality":

In 1900, American paleontologist Nathanial Shaler notably discussed immortality and the conservation of energy.

In 1906, German physical chemist Wilhelm Ostwald famously gave his Ingersoll lecture on “Individuality and Immortality”. [1]

In 1994, American physicist Frank Tipler proposed his second law themed omega point theory of immortality.

In 2013, writer Adam Gollner, in his The Book of Immortality, discusses how in his reading of the Immortality Institute’s collection of essays, he learned that many so-called immortalists align themselves with a movement called extropianism, meaning without entropy, based on their guru Max More.
