hypothetical activity of traveling into the past or future

theories of physics that predate modern, more complete, or more widely applicable theories

In philosophy (metaphysics), physicalism is the position that everything is physical, that there is nothing over and above the physical, and that everything supervenes on the physical. It stands in direct opposition to idealism, which asserts that reality arises from the mind. Physicalism is a form of ontological monism—a single-substance account of the nature of reality, in contrast to "two-substance" (mind–body dualism) or "many-substance" (pluralism) views. Physicalism is closely related to naturalism, though important distinctions exist between them.

Even though the Sun is about 400 times bigger than the Moon, it is also about 400 times farther away. This makes the Sun and the Moon appear almost exactly the same size in our sky. |thumb|Solar eclipse of August 21, 2017|A total solar eclipse at Orin Junction, Wyoming in 2017.

In physics and mathematics, an ansatz (; , meaning: "initial placement of a tool at a work piece", plural ansatzes or, from German, ansätze ; ) is an educated guess or an additional assumption made to help solve a problem, and which may later be verified to be part of the solution by its results.

In quantum mechanics, superdeterminism is a loophole in Bell's theorem. By postulating that all systems being measured are correlated with the choices of which measurements to make on them, the assumptions of the theorem are no longer fulfilled. A hidden variables theory which is superdeterministic can thus fulfill Bell's notion of local causality and still violate the inequalities derived from Bell's theorem. This makes it possible to construct a local hidden-variable theory that reproduces the predictions of quantum mechanics, for which a few toy models have been proposed. In addition to bei

In philosophy, four-dimensionalism (sometimes called the doctrine of temporal parts) is a family of views about the ontology of time and persistence. Roughly, four-dimensionalists hold that persisting objects are extended in time in a way analogous to their extension in space, and that they are composed of distinct temporal parts located at different times, in addition to their spatial parts.
