The Arrow of Time

On the Arrow of Time

The interface between classical physics and quantum physics is explained from the point of view of quantum information theory (Feynman Processes). The interpretation depends on a hefty sacrifice: the classical determinism or the arrow of time. The wave-particle duality steams from the qubit model, as the root of creation and annihilation of possibilities. A few key experiments are briefly revie...

On the Arrow of Time

We believe the following three ingredients are enough to explain the mystery of the arrow of time: (1). equations of dynamics of gas molecules, (2). chaotic instabilities of the equations of dynamics, (3). unavoidable perturbations to the gas molecules. The level of physical rigor or mathematical rigor that can be reached for such a theory is unclear. 1. The theory. There have been a lot of wri...

The Arrow Of Time In The Landscape

The future is unlike the past. This is an absolutely basic observation, as basic as the observation that “things fall”. We expect that a real understanding of the Arrow of Time — the temporal “direction” defined by the physical differences between the future and the past — will arise only in the context of some deep theory, such as string theory. Conversely, we argue here that such an understan...

A compromised arrow of time

The second law of thermodynamics—the usual statement of the arrow of time—has been called the most fundamental law of physics. It is thus difficult to conceive that a single dynamical system could contain subsystems, in significant mutual contact, possessing opposite thermodynamic arrows of time. By examining cosmological justification for the usual arrow it is found that a consistent way to es...
