<b>Merging Black Holes: Insights from</b> <b>Gravitational Wave Observations</b>

Before the first formal and direct detection of gravitational waves happened in 2015 by LIGO, Einstein had already predicted its presence in 1916 through his theory of general relativity. These gravitational waves are produced in cosmic events such as colliding and merging black holes, which means that their detection and investigation can be used to study the characteristics and properties of Black Hole Mergers. Studying black hole mergers can enable us to gain a deeper understanding of the universe’s cosmic history and structure. This paper provides a brief summary on the insights of Black Hole mergers from Gravitational Wave Observations, while also exploring some of the observational technique used, such as the technique of interferometry and Pulsar Timing arrays.
