Question

Define them : Uncertainty principle, Pauli exclusion principle, wave function collapse and one - electron universe and quantum cosmology. I will mark as brainliest if not copied from net and have correct details and also explain in detail.

Answer 1

Heisenbergs uncertainity principle states that 'it is impossible to determine simultaneously both the position and velocity ( momentum) of a microscopic moving particle such as electron with absolute accuracy.

paulis exclusion principle:
It states that no two electrons in an atom can have the same values for all the four quantum numbers.
Thus, capacity of each orbital is limited to " two ".

Wave function collapse is a discontinuous change in the state of a quantum system associated with measurement. In contrast with the continuous evolution of the wave function of an unobserved system according to the Schrödinger equation which produces a superposition of different states, when a system is observed it is not found to be in a superposition but in a single state (e.g., Schrödinger's cat is observed to be either dead or alive, but not a superposition of dead and alive states). The collapse of the wave function is the term used to describe this discontinuous transition from a coherent superposition of states to a single state upon measurement.The nature of wave function collapse is a matter of interpretation, and understanding it is a key aspect of the measurement problem of quantum mechanics. Some interpretations assert that there is no real physical process of collapse at all: what appears as collapse is actually a result of decoherence. The phenomenon of decoherence provides a mechanism for understanding how, due to coupling of the system with the environment, the coherence of the system's wave function becomes for all practical purposesunobservable. However, the coherence can not actually be destroyed or lost by means of a continuous evolution in accordance with the Schrödinger equation. Thus, decoherence alonedoes not provide a solution to the measurement problem.
