Classical Spacetimes of Bouncing Universes and Evaporating

Page ID 1285; Contributors; Physics describes evolution: it tells how, given some initial state, a system will look at later times. To describe the earliest moments of the Universe in quantum cosmology, we need to have some idea about the initial conditions, or "boundary conditions" at the beginning of time.

The No-Boundary Measure in the Regime of Eternal Inflation

‘seed’ state of matter to a dS-invariant state, as all physical states must be in quantum gravity. (Actually, all physical states must be invariant under the full diffeomorphism group, but the de Sitter group is a crucial subgroup of this when there is a positive cosmological constant,

Can quantum cosmology have a starting state? Physics

Abstract. Contemporary final theories consist of a theory of the universe’s dynamics (I) like the avatars of string theory together with a theory of its quantum state (Ψ) like the no-boundary wave function of the universe (NBWF).

"A New Picture of the Big Bang"-The Quantum Universe

The no boundary proposal, predicts that the universe would start at a single point, like the north pole of the Earth. But this point wouldn't be a singularity, like the Big Bang. Instead, it would be an ordinary point of space and time, like the north pole is an ordinary point on …

James Hartle The bubble multiverses of the no-boundary

Abstract. In the no-boundary Universe of Hartle and Hawking, the path integral for the quantum state of the Universe must be summed only over nonsingular histories.

On the initial state of the Universe in quantum cosmology

The Quantum Vacuum and the Cosmological Constant Problem S.E. Rugh…and H. Zinkernagely To appear in Studies in History and Philosophy of Modern Physics Abstract - The cosmological constant problem arises at the intersection be-tween general relativity and quantum field theory, and is regarded as a fun-damental problem in modern physics. In this paper we describe the historical and

On the initial state of the Universe in quantum cosmology

quantum state space for the gravity system and gravity matter system are very limited and the definition of the inner-product in quantum state space has not been found. A natural query is what happened before unification–may be called super unified field.

The State of the Universe CORE

Quantum Cosmology The physical laws that govern the universe prescribe how an initial state evolves with time. In classical physics, if the initial state of a system is specified exactly then the subsequent motion will be completely predictable.

Appearance of a classical mixmaster universe from the no

We analyze the classical spacetime predicted by Hawking’s no-boundary quantum state for a class of minisuperspace models. The quantum state of the universe is the key to the origin of classical spacetime. Minisuperspace Models Geometry: Homogeneous, isotropic, closed. Matter: cosmological constant Λ plus homogeneous scalar field moving in a quadratic potential. Theory: Low-energy …
