Time and Causation

TL;DR

This review explores the fundamental concepts of time and causality within relativity theories, addressing paradoxes, the directionality of time, and issues in quantum gravity.

Contribution

It provides a comprehensive overview of the philosophical and physical challenges related to time and causality in modern physics.

Findings

Analysis of closed timelike curves and their paradoxes

Discussion on the directionality of time in relativity

Brief overview of the problem of time in quantum gravity

Abstract

In this review paper, we consider the fundamental nature of time and causality, most particularly, in the context of the theories of special and general relativity. We also discuss the issue of closed timelike curves in the context of general relativity, and the associated paradoxes, the question of directionality of the time flow and, rather briefly, the problem of time in quantum gravity.
