Analysis Of the Principle, Facility, And Applications of Gravitational Wave

Abstract

When Einstein published his general relativity at the beginning of last century, gravitational wave was predicted in the study. It has been the hottest topic in astronomy, and countless astronomers have studied them. This includes the principles of gravitational wave generation, detection methods, observations, etc. This article will focus on a review of gravitational wave research, and comprehensively write down the gravitational wave research results so far from the perspectives of basic mathematical description, detection principles, detection methods and applications, and future prospects. This study gives a mathematical description of gravitational waves, including calculation formulae for the energy they carry, their amplitude, and their impact on passing objects. In addition, this article also introduces several mainstream methods for detecting gravitational waves today, and details the applications of these methods, such as MiniGRAIL, LIGO, LISA and other detection devices. Finally, the article describes expected developments in gravitational wave detection over the next decade. Based on studying and detecting gravitational waves, humans can detect many astronomical events that cannot be detected with existing methods, and gain a deeper understanding of the universe.
