hypothesis that humans possess an innate tendency to seek connections with nature and other forms of life

hypothesis that alien life has not been discovered because alien civilizations are silent and very cautious

theory regarding lack of alien contact

thesis that it is impossible to test a scientific hypothesis in isolation, because such an empirical test of it requires other assumptions

hypothesis added to a theory in order to save it from being falsified

conjecture that, in general relativity, there is no naked singularity (i.e. one visible from future null infinity) generically

economic theory that one’s consumption at some time is determined not just by current income but also by expected income in future years (“permanent income“)

hypothesis

in the early days of the Solar System, Jupiter moved inward then reversed course ("tacked") to its current orbit

non-mainstream theory in physics remaining to be validated

hypothesis that the Gospel of Mark was used as a source by the other synoptic gospels (Matthew and Luke)

hypothesis that typical physical systems studied in statistical mechanics are ergodic, such that time averages equal phase space averages

overview about the Egyptian pyramid construction techniques

Hypothesis in evolutionary biology

model of economic consumption

assessment of modern science's ability to detect evidence of a prior advanced civilization

hypothesis that multicellular life, understood as a superorganism, is suicidal, and that microbial-triggered mass extinctions are attempts to return the Earth to a microbial-dominated state

asteroid impact hypothesis as cause of the Cretaceous–Paleogene extinction

hypothesis

idea that any intelligent life is destroyed by aliens

Molecular biology hypothesis

solution to the synoptic problem, according to which Matthew was written first, Mark second and depending on Matthew, and Luke in turn depending on Matthew and Mark

hypothesis, posited and soon abandoned in the 1890s by Freud, that a repressed memory of early childhood sexual abuse is the essential precondition for hysteria or obsessional neurosis (along with active sexual experience up to age 8 for the latter)

solution to the synoptic problem that Mark was written first, that Matthew used Mark, and that Luke used Mark and Matthew

solution to the Fermi paradox by holding that our astronomical observations represent an illusion

economic theory

hypothesis which claims that the first produced or compiled gospel was that of Marcion and that this gospel of Marcion was used as inspiration either for some of the canonical gospels, or for all the canonical gospels (Matthew, Mark, Luke, and John)

hypothesized solution to the Fermi paradox that alien civilizations are storing energy and hibernating till the universe cools to make better use of stored energy to do tasks

hypothesis that is provisionally accepted as a basis for further research in the hope that a tenable theory will be produced
