Abstract
The conventional singular hot big bang scenario is questioned. A new model which does not include an initial singularity g00 = ∞ at t = 0, neither a brief period of exponential expansion a(t)~eHt is considered. The main parameters T and ρ are kept finite. The beginning of the universe we occupy is revisited in the framework of quantum field theory in curved spacetime. However, a straightforward alternative mechanism for not only solving the most fundamental problems in modern cosmology-flatness problem, horizon problem and magnetic monopole problem, but even suppressing their number is provided. In the particular paper, we discuss the essential role quantum entanglement plays in the structure of the spacetime and the apparent contradiction between quantum mechanics and general relativity in terms of classical field theory in 3 + 1 dimensions.
Highlights
For the past decades, the prevailing view, regarding the beginning of the universe and its evolution in the first fraction of a second, has been a combination of the big bang theory and the theory of cosmic inflation [1]
We will first discuss the apparent contradiction between quantum mechanics and general relativity by conducting a simple gedanken experiment
The phenomena show the crucial role quantum mechanics plays in the early history of the universe
Summary
The prevailing view, regarding the beginning of the universe and its evolution in the first fraction of a second, has been a combination of the big bang theory and the theory of cosmic inflation [1] We are not going to provide a detailed description of inflation, neither will we examine its different models, as this is not of interest to the particular paper Great effort in this direction has been devoted in the past [2]-[4]. We put forward a novel way for explaining the cosmological principle by making certain assumptions regarding the structure of spacetime in terms of tiny wormholes, and provide a mechanism for their natural arising
