Davies1 has argued that the inflationary cosmological scenario2–5 provides a natural explanation for the time asymmetry of the Universe. Here I dispute this argument by noting that the inflationary scenario implicitly invokes time asymmetry with the assumption of an absence of initial spatial correlations. No scenario based on charge-parity-time (CPT)-invariant dynamical laws can explain the time asymmetry apart from postulating or explaining these special initial conditions, as Penrose6,7 has… 

Inflation in the universe and time asymmetry

I previously argued that the origin of time asymmetry is to be sought in the processes that characterized the very early cosmological epochs, and that the recent inflationary scenario provides a

Can inflation explain the second law of thermodynamics?

The inflationary model of the universe can explain several of the cosmological conundra that are mysteries in the standard hot big bang model. Paul Davies has suggested that inflation can also

Violation ofCPT invariance in the typical universe

SummaryWe show that the understanding of the problem of time asymmetry can be reached proceeding from the hypothesis of typicalness of the Universe. We come to the following consequences: 1) the

Does inflation provide natural initial conditions for the universe

If our universe underwent inflation, its entropy during the inflationary phase was substantially lower than it is today. Because a low-entropy state is less likely to be chosen randomly than a

Cyclic Inflation

We present an inflationary model that is geodesically complete and does not suffer from the transplanckian problem. In most inflationary models, massless (conformal) scalar field fluctuations in a

de Sitter equilibrium as a fundamental framework for cosmology

Cosmology might turn out to be the study of fluctuations around a "de Sitter equilibrium" state. In this article I review the basic ideas and the attractive features of this framework, and respond to

Time's Arrows Today: Cosmology, time's arrow, and that old double standard

It is widely accepted that temporal asymmetry is largely a cosmological problem; the task of explaining temporal asymmetry reduces in the main to that of explaining an aspect of the condition of the

Multiverse Cosmological Models

Recent advances in string theory and inflationary cosmology have led to a surge of interest in the possible existence of an ensemble of cosmic regions, or "universes", among the members of which key

The quantum origins of the cosmological asymmetry

The standard inflationary version of the origin of the cosmic structure as the result of the quantum fluctuations during the inflationary stage is less than fully satisfactory: how exactly does the

Inflation and the False Vacuum

Inflation is the idea that the very early universe may have been dominated by vacuum energy, giving rise to a brief period of vastly accelerated expansion. Its roots go back to the late 1960s and the



Inflation and time asymmetry in the Universe

The recently proposed inflationary Universe scenario1–4 explains several of the mysteries of modern cosmology. I argue here that it also provides a natural explanation for the origin of time

Cosmology for Grand Unified Theories with Radiatively Induced Symmetry Breaking

The treatment of first-order phase transitions for standard grand unified theories is shown to break down for models with radiatively induced spontaneous symmetry breaking. It is argued that proper

Evolution of perturbations in an inflationary universe

We analyze the evolution of inhomogeneous density perturbations in a model of the very early universe that is dominated for a time by a constant energy density of a false quantum-mechanical vacuum,

Inflationary universe: A possible solution to the horizon and flatness problems

The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: (1) The early universe is assumed to be highly homogeneous, in spite of the fact that

Cosmological Production of Superheavy Magnetic Monopoles

Grand unified models of elementary particle interactions contain stable superheavy magnetic monopoles. The density of such monopoles in the early universe is estimated to be unacceptably large.

The Direction of Time

It is argued, using a relativistic space-time view of the Universe, that Reichenbach’s “principle of the common cause” provides a good basis for understanding the time direction of a variety of
