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.
