If he were to implant his Copy into the TVC universe, have the copy run a number of experiments to anchor itself in that universe, and then terminate it, only to find himself still in the TVC universe ( indeed, the purpose of growing the TVC universe from a Garden of Eden configuration was to prove to his Copy that such a TVC universe as it found itself to inhabit must have been launched from a non-TVC universe, as opposed to merely having always existed and evolved towards this the current state in which he did not know whether it had ) rather than back in " the real world " again, then he would be vindicated ; if not, then his hypothesis would be falsified and he might consider himself crazy ( his last several experiences of termination and subsequent continuation involved him finding himself in the position of having been recently cured of psychosis ).

The eocyte hypothesis proposed in the 1980s by James Lake suggests that eukaryotes evolved from the prokaryotic eocyte.

Having evolved from the heuristics of Tversky and Kahneman into the creeping determinism hypothesis and finally into the hindsight bias as we now know it, the concept has many practical applications and is still at the forefront of research today.

Based on the RNA world theory of life, the Virus First hypothesis proposes that viruses evolved from the very first segments of RNA, predating the early cells.

An early psychical researcher to propose an afterlife hypothesis was Edmund Fournier d ' Albe he wrote that at the moment of death the soul floats into the atmosphere.

One of the most frequent speculations is that the entire book ( excepting 9: 4-20 ) was originally written in Aramaic, with portions translated into Hebrew, possibly to increase acceptance-many Aramaisms in the Hebrew text find proposed explanation by the hypothesis of an inexact initial translation into Hebrew.

Charles Darwin proposed the theory of universal common descent through an evolutionary process in On the Origin of Species, twice stating the hypothesis that there was only one progenitor for all life forms and ending with " There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one ".

Wegener was the first to use the phrase " continental drift " ( 1912, 1915 ) ( in German " die Verschiebung der Kontinente " – translated into English in 1922 ) and formally publish the hypothesis that the continents had somehow " drifted " apart.

The history of quantum chemistry essentially began with the 1838 discovery of cathode rays by Michael Faraday, the 1859 statement of the black body radiation problem by Gustav Kirchhoff, the 1877 suggestion by Ludwig Boltzmann that the energy states of a physical system could be discrete, and the 1900 quantum hypothesis by Max Planck that any energy radiating atomic system can theoretically be divided into a number of discrete energy elements ε such that each of these energy elements is proportional to the frequency ν with which they each individually radiate energy and a numerical value called Planck ’ s Constant.

The long accepted " competing browser's hypothesis " by Charles Darwin is now being put into question.

This hypothesis would lay the intellectual groundwork for the British philosopher Max More to begin articulating the principles of transhumanism as a futurist philosophy in 1990, and organizing in California an intelligentsia that has since grown into the worldwide transhumanist movement.

According to this approach, it is not necessary to assign any value to the probability of a hypothesis, although one must certainly take into account the probability of the data given the hypothesis, or given a competing hypothesis, when deciding whether to accept or to reject.

In 1780, for example, Laplace and Lavoisier stated: “ In general, one can change the first hypothesis into the second by changing the words ‘ free heat, combined heat, and heat released ’ into ‘ vis viva, loss of vis viva, and increase of vis viva .’” In this manner, the total mass of caloric in a body, called absolute heat, was regarded as a mixture of two components ; the free or perceptible caloric could affect a thermometer, whereas the other component, the latent caloric, could not.
