The Physics of Time: Current Knowledge and Unanswered Challenges

TL;DR

This paper explores the complex relationship between space and time in physics, examining how their intertwined nature contrasts with everyday perception and analyzing the fundamental property of time's evolution.

Contribution

It provides a conceptual analysis of the physical nature of time and its distinction from space, addressing unresolved questions in current physical theories.

Findings

Space and time are intertwined in physics but perceived separately in everyday life.

Time uniquely evolves from past to future, a property analyzed in the context of physical theories.

The paper discusses unresolved challenges in understanding the nature of time.

Abstract

In contemporary physics space and time are intertwined entities so that kinematical and dynamical quantities are expressed in the four-dimensional space-time. This formulation seems to contradict our every-day experience and perception according to which space and time are distinct entities. In this brief report we shall discuss these apparently antagonist views and analyse the underlying physical property of time, namely that it evolves from the past to the present, from the present to the future.
