In particle physics, the hidden sector, also known as the dark sector, is a hypothetical collection of yet to be observed quantum fields and their corresponding hypothetical particles. The interactions between the hidden sector particles and the Standard Model particles are weak, indirect, and typically mediated through gravity or other new ...
A theory of everything (TOE), final theory, ultimate theory, unified field theory, or master theory is a hypothetical singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe.
Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement.
She started making science videos while working as a mobile app developer at General Electric. [11] She started her channel Physics Girl on October 21, 2011. [12] In an interview with Grant Sanderson, she said that some of the earlier videos were later deleted from the channel. [9] Cowern has also participated in various events as a speaker.
Indeed operates in the UK via Indeed UK Operations Ltd, which is a subsidiary of Indeed Operations Ireland Ltd, whose ultimate holding company is Recruit Holding Co Ltd. Turnover in the UK for the year to 31 December 2019 was £41.2m. [citation needed] On October 1, 2012, Indeed became an independent operating unit of Japan-based Recruit Co ...
Another no-go theorem concerning hidden-variable theories is the Kochen–Specker theorem. Physicists such as Alain Aspect and Paul Kwiat have performed experiments that have found violations of these inequalities up to 242 standard deviations. [29] This rules out local hidden-variable theories, but does not rule out non-local ones.

In the interpretation of quantum mechanics, a local hidden-variable theory is a hidden-variable theory that satisfies the principle of locality.These models attempt to account for the probabilistic features of quantum mechanics via the mechanism of underlying, but inaccessible variables, with the additional requirement that distant events be statistically independent.
