Extrascience

Extrascience is a term used to refer to everything that is outside natural sciences and usually cannot be studied by the scientific method. Furthermore, extrascience is usually used to refer to sciences related to spirituality, philosophy, occult, metaphysics and extraphysics in a way they are outside natural sciences and should have a non-positivist approach when studied.
"Extrascience is actually a critic to the excessive positivism of nowaday, furthermore, extrascience is a good way to study about extranatural things without need to have positivist recognition or similar."

Extrascience

Extrascience describes hypothetical or future forms of science that extend beyond current physical laws, dimensions, or epistemological limits. It assumes that existing scientific frameworks are incomplete and that new principles are required to study extraphysical realities, multiverses, or non-material structures. Unlike parascience, extrascience is often framed as a continuation of science rather than an alternative to it. It imagines tools, methods, and theories capable of measuring probability dimensions, consciousness layers, or reality-branching mechanisms, functioning as a proposed successor to modern physics rather than a rejection of it.
Extrascience — Example

A future civilization develops instruments capable of measuring probability gradients across branching universes. Using these tools, they map decision points and predict which future timelines are most likely to stabilize. This new discipline extends beyond physics into extrascience, requiring laws that govern probability dimensions rather than spacetime alone.

Extrascience Theory

A conceptual framework that explicitly deals with phenomena claimed to be beyond the current reach or proper domain of conventional scientific investigation. It doesn't just run parallel; it points to a territory science hasn't (or can't) map, like the nature of a soul or the meaning of mystical experience. It's the proposal for an annex to the empire of knowledge that science hasn't yet claimed.
Example: "A theory proposing that near-death experiences provide evidence for non-local consciousness surviving bodily death is an Extrascience Theory. It tackles a topic (the afterlife) that mainstream science, by its materialist methods, currently excludes from consideration. It argues for expanding the map, not just taking a different path on the existing one."

Extrascientism 

Extrascientism, also extrascientificism, id the idea that extrasciences such as extraphysics, metaphysics, spirituality, esoterics, occultism, astrality and supernaturality, and other spiritual sciences and supernatural sciences, are more important and superior than natural sciences in explaining nature, reality and existence, such as extraphysicalism and extramaterialism are philosophically and epistemologically superior than physicalism and materialism on explaining about reality and existence. Extrascientism also advocates that extrasciences should be promoted as the best and only objective means by which society should determine normative, epistemological and spiritual values.
"Extrascientism might be bad such as scientism actually is, but it would be a nice way to balance scientism and balance society as well, such as show that spirituality (spiritual sciences) and supernaturality (supernatural sciences) can also have the same recognition that natural sciences have nowadays, and even show that both things can be united and work together."
