Quantum superposition is a fundamental principle of quantum mechanics that states that linear combinations of solutions to the Schrödinger equation are also solutions of the Schrödinger equation. This follows from the fact that the Schrödinger equation is a linear differential equation in time and position.
In theoretical physics, top-down cosmology is a proposal to regard the many possible histories of a given event as having real existence. [1] This idea of multiple histories has been applied to cosmology, in a theoretical interpretation in which the universe has multiple possible cosmologies, and in which reasoning backwards from the current state of the universe to a quantum superposition of ...
Penrose's idea is inspired by quantum gravity because it uses both the physical constants and .It is an alternative to the Copenhagen interpretation which posits that superposition fails when an observation is made (but that it is non-objective in nature), and the many-worlds interpretation, which states that alternative outcomes of a superposition are equally "real," while their mutual ...
About 50 years ago, quantum physicists suggested that the universe could be trapped in a so-called false vacuum, where it appears stable but could be about to move into a true vacuum and be even ...
In quantum physics, a particle does not exist in the way classical physics observes it, with a definite physical location. Instead, it exists as a cloud of probabilities.
Experiments at the atomic scale have been carried out, showing that very small objects may exist as superpositions; but superposing an object as large as a cat would pose considerable technical difficulties. [3] Fundamentally, the Schrödinger's cat experiment asks how long quantum superpositions last and when (or whether) they collapse
Before the eyes of 77 other brilliant scientists, who had all gathered in the Austrian capital to discuss the nascent field of quantum theory, Einstein insisted that quantum states had their own ...
Nevertheless, on the topic of quantum superposition, Kramers writes: "The principle of [quantum] superposition ... has no analogy in classical physics" [citation needed]. According to Dirac: "the superposition that occurs in quantum mechanics is of an essentially different nature from any occurring in the classical theory [italics in original]."
