As a result, some of the superfluid properties of the A and A1 phases are markedly different from those of 4He or 3He-B and are indeed unique among known physical systems. This video explains String Theory in Hindi. Thank you. To this day, physicists do not have a convincing explanation for why action in microcosm is quantized or why h has a specific quantitative value. Here, have some! As a result, as the temperature is lowered and the fraction of condensed atoms increases, the liquid will appear gradually to come to rest with respect to the laboratory (or, more accurately, to the fixed stars). "An Exceptionally Simple Theory of Everything" is a physics preprint proposing a basis for a unified field theory, often referred to as "E 8 Theory", which attempts to describe all known fundamental interactions in physics and to stand as a possible theory of everything. There is even a quantum theory of gravity (a possible ‘theory of everything’) that treats the fundamental vacuum as a kind of superfluid. Please select which sections you would like to print: While every effort has been made to follow citation style rules, there may be some discrepancies. accept that before the big bang was a ceph (SF) (superfluid). An ultimate goal of this approach is to develop scientific … Quantum Hall effect A superfluid Theory of Everything? Theory of Everything (TOE) - Superfluid Universe. The other characteristic manifestations of superfluidity can be explained along similar lines. Our editors will review what you’ve submitted and determine whether to revise the article. Physicists now suggest that spacetime may itself be a fluid, a very slippery type known as a superfluid. Superfluid vacuum theory, sometimes known as the BEC vacuum theory, is an approach in theoretical physics and quantum mechanics where the fundamental physical vacuum is viewed as superfluid or as a Bose–Einstein condensate. Here, have some! It is thought that there is a close connection between the phenomena of superfluidity and superconductivity; indeed, from a phenomenological point of view superconductivity is simply superfluidity occurring in an electrically charged system. In each case the unusual behaviour arises from quantum mechanical effects. A theory of everything ( ToE) or final theory is a putative theory of theoretical physics that fully explains and links together all known physical phenomena, and predicts the outcome of any experiment that could be carried out in principle. These things are clearly The microscopic structure of this physical vacuum is currently unknown and is a subject of intensive studies in SVT. ... De Aquino, F. (2012) The Universal Quantum Fluid, in the Theory of Everything. Many other characteristic features of superconductivity, such as the existence of vortices and the Josephson effect, have been observed in the superfluid phases of both 4He and 3He. Another property is less spectacular but is extremely significant for an understanding of the superfluid phase: if the liquid is cooled through the lambda transition in a bucket that is slowly rotating, then, as the temperature decreases toward absolute zero, the liquid appears gradually to come to rest with respect to the laboratory even though the bucket continues to rotate. The microscopic structure of this physical vacuum is currently unknown and is a subject of intensive studies in SVT. Here, two points are reasonably well as the SAHA with the Spacetime with Light and Sound is nothing but the Quantum Vacuum or the Superfluid Vacuum Theory (Quantum Superfluid Theory the QST) while also embracing the Quantum Space Theory (the SAHA, the Spacetime as the Quantum Fractal Systems) and the Special Dimensions of the O (1-D), A (2-D), E (3-D), AE (4-D) jump to make the … Marco Fedi To cite this version: Marco Fedi. (The transition to the superfluid phase is called the lambda-transition.) (The reason that this phenomenon is not seen in other systems of spin-zero atoms such as neon-22 is simply that, as the temperature is lowered, freezing occurs first.) Related phenomena observed in the superfluid phase include the ability to sustain persistent currents in a ring-shaped container; the phenomenon of film creep, in which the liquid flows without apparent friction up and over the side of a bucket containing it; and a thermal conductivity that is millions of times its value in the normal phase and greater than that of the best metallic conductors.

SPACETIME SUPERFLUID SOUP TO GO J Mark Morris January 2019, Updated December 2019 In January 2018, I began developing a “theory of everything”, or more precisely, a unifying theory of nature that surpasses general relativity, quantum mechanics. Planck’s constant h is a fundamental physical constant defined in the realm of quantum theory and is determined only by physical measurement and cannot be calculated. A gas of such atoms without interactions between them would undergo, at some temperature T0, a phenomenon known as Bose condensation; below T0 a finite fraction of all the atoms occupy a single state, normally that of lowest energy, and this fraction increases toward one as the temperature falls toward absolute zero. String theory and M-theory have been proposed as theories of everything. Similarly, a single atom (or molecule) placed in a ring-shaped container is allowed by quantum mechanics to travel around the ring with only certain definite velocities, including zero. In a superfluid system the situation is quite different. The accepted theoretical understanding of superfluidity (or superconductivity) is based on the idea that an extremely large number of atoms (or electrons) show identical, and moreover essentially quantum mechanical, behaviour; that is to say, the system is described by a single, coherent, quantum mechanical wave function. in some cold atomic systems.

Superfluid vacuum theory (SVT), sometimes known as the BEC vacuum theory, is an approach in theoretical physics and quantum mechanics where the fundamental physical vacuum (non-removable background) is viewed as superfluid or as a Bose–Einstein condensate (BEC). and current era physics / cosmology. Get a Britannica Premium subscription and gain access to exclusive content. Theory Of Everything. Inside the tube an isotope of helium (called helium three) forms a "superfluid", an ordered liquid where all the atoms are in the same state according to the theory that rules the subatomic domain, called quantum theory. Superfluidity, the frictionless flow and other exotic behaviour observed in liquid helium at temperatures near absolute zero (−273.15 °C, or −459.67 °F), and (less widely used) similar frictionless behaviour of electrons in a superconducting solid. Omissions? Superfluid vacuum theory (SVT), sometimes known as the BEC vacuum theory, is an approach in theoretical physics and quantum mechanics where the fundamental physical vacuum (non-removable background) is viewed as superfluid or as a Bose–Einstein condensate (BEC).. These atoms are said to be condensed. Well, in the light of above mockery we might consider that action measures the change in angular momentum of the system – most of it “intrinsic angular momentum” that cannot be detected as rotation of the whole ensemble but rather as internal energy or “mass”.
