Flashcards: Hypotheses

In mathematics, the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and the complex numbers with real part 1/2.

In logic, and especially in its applications to mathematics and philosophy, a counterexample is an exception to a proposed general rule or law.

In planetary astronomy and astrobiology, the Rare Earth Hypothesis argues that the origin of life and the evolution of biological complexity such as sexually reproducing, multicellular organisms on Earth (and, subsequently, human intelligence) required an improbable combination of astrophysical and geological events and circumstances.

The just-world hypothesis is the assumption that a person's actions are inherently inclined to bring morally fair and fitting consequences to that person, to the end of all noble actions being eventually rewarded and all evil actions eventually punished.

The heat death of the universe is a possible ultimate fate of the universe in which the universe has diminished to a state of no thermodynamic free energy and therefore can no longer sustain processes that increase entropy (including computation and life).

Nuclear winter (also known as atomic winter) is a hypothesized global climatic effect most often considered a potential threat following a countervalue (or city-targeted), nuclear war, as a result of city and natural wildfire firestorms.

The idea of self-replicating spacecraft has been applied – in theory – to several distinct "tasks".

In future studies, human extinction is the hypothetical end of the human species.

Linguistic relativity, also known as the Sapir–Whorf hypothesis or Whorfianism, is a concept-paradigm in linguistics and cognitive science that holds that the structure of a language affects its speakers' cognition or world view.

The technological singularity (also, simply, the singularity) is the hypothesis that the invention of artificial superintelligence will abruptly trigger runaway technological growth, resulting in unfathomable changes to human civilization.

Tetrahedrane is a platonic hydrocarbon with chemical formula C4H4 and a tetrahedral structure.

In physics and cosmology, the mathematical universe hypothesis (MUH), also known as the Ultimate Ensemble, is a speculative "theory of everything" (TOE) proposed by the cosmologist Max Tegmark.

The input hypothesis, also known as the monitor model, is a group of five hypotheses of second-language acquisition developed by the linguist Stephen Krashen in the 1970s and 1980s.

A working hypothesis is a hypothesis that is provisionally accepted as a basis for further research in the hope that a tenable theory will be produced, even if the hypothesis ultimately fails.

The variability hypothesis originated in the early nineteenth century with Johann Meckel, who argued that males have a greater range of ability than females, especially in intelligence.

The two-gospel hypothesis is that the Gospel of Matthew was written before the Gospel of Luke, and that both were written earlier than the Gospel of Mark.
