Covariance, relativity, and the proper mass of the universe in the no-boundary wave function
Natalia Gorobey, Alexander Lukyanenk, A. V. Goltsev
A discrete class of privileged reference frames in a closed universe with identical equations of motion for physical degrees of freedom was found. A representation of the quantum s…
CPT symmetry in the mirror universe
Natalia Gorobey, Alexander Lukyanenko, A. V. Goltsev
A model of a two-sheeted universe in the quantum theory of gravity is proposed, based on the definition of 3D invariant and gauge-invariant proper time of the universe. A uniform t…
Observer in quantum cosmology
Natalia Gorobey, Alexander Lukyanenko, Alexander V. Goltsev
Within the framework of the new formalism of quantum theory - the quantum principle of least action - the initial state of the universe is determined, which is an analogue of the H…
No-boundary Wave Functional and Own Mass of the Universe
Natalia Gorobey, Alexander Lukyanenko, A. V. Goltsev
An alternative formulation of the no-boundary initial state of the universe in the Euclidean quantum theory of gravity is proposed. Unlike the no-boundary Hartle-Hawking wave funct…
