The Physics of Dead Grandmothers

In this article, we will Delve into the fascinating realm where physics intersects with existential questions about life, time, and the afterlife. The inspiration for this exploration comes from a curious encounter in a taxi, where a young man asked a physicist about the relationship between quantum mechanics and the existence of his deceased grandmother. As we unravel this topic, we will first explain the basics of quantum mechanics and Einstein's theory of special relativity, which are the foundations for understanding the nature of time. We will then explore the concepts of "now," the relativity of simultaneity, and the block universe where past, present, and future coexist. Additionally, we will discuss the scientific viewpoint on information preservation and retrieval, including unresolved issues related to black holes and quantum measurement. By the end, we hope to provide you with a deeper understanding of how physics can shed light on life's biggest questions.

Introduction

The encounter in the taxi sparked a thought-provoking conversation between a physicist and a young man seeking answers. As the physicist introduced herself as a scientist specializing in physics, the young man was eager to ask a question about quantum mechanics. Intrigued, the physicist encouraged him to proceed. The young man revealed that a shaman had shared with him a belief that his deceased grandmother was still alive due to quantum mechanics. Although the connection to quantum mechanics was not accurate, the physicist recognized the underlying question about the reality of time, which lies at the heart of the matter. Throughout this article, we will explore the realm where physics meets existential questions and attempt to shed light on the nature of time and existence. Let's embark on this Journey by understanding the fundamentals of quantum mechanics and Einstein's theory of special relativity.
