Quantum Gravity’s Time Problem

12/31/2016

This article discusses the concept of time in the context of quantum gravity. It explores the ongoing search for a theory that harmoniously combines quantum mechanics and general relativity. The article highlights the challenges that arise when trying to reconcile these two fundamental theories, particularly when it comes to the definition and understanding of time. It delves into various approaches and theories proposed by physicists, such as loop quantum gravity and string theory, that attempt to address the so-called 'time problem' in quantum gravity. The article also explores the potential implications of finding a resolution to this problem, including the possibility of shedding light on the nature of the universe itself.
