Abstract

Since the landmark detection of GW150914 by the LIGO Scientific Collaboration in 2015, gravitational wave (GW) astronomy has transitioned from a theoretical frontier to a robust observational science. This breakthrough confirmed a major prediction of General Relativity and inaugurated an entirely new method for observing the universe. Over the past decade, continuous upgrades to ground-based interferometers such as LIGO, Virgo Collaboration, and KAGRA have dramatically improved detector sensitivity, enabling the discovery of dozens of compact binary mergers involving black holes and neutron stars. These observations have deepened our understanding of stellar evolution, compact object formation, and the dynamics of extreme astrophysical environments This review synthesizes the progress made in the decade following the first detection, highlighting not only the refinement of existing observatories but also the emergence of innovative detection paradigms. Among the most significant recent discoveries is the recording of the “cleanest” black hole merger to date, GW250114, whose exceptionally high signal-to-noise ratio has enabled some of the most precise tests yet of General Relativity under strong gravitational fields. The event has provided valuable constraints on alternative gravity theories and has reinforced confidence in current models of black hole dynamics In parallel, the field has increasingly shifted toward multi-messenger astrophysics, combining gravitational wave data with electromagnetic observations, neutrino detections, and high-energy particle measurements. This integrated approach allows researchers to investigate cosmic events with unprecedented depth and accuracy, particularly in neutron star mergers and supernova studies. Looking ahead, theoretical developments in atomic-scale and quantum-enhanced GW detection suggest the possibility of probing gravitational phenomena at previously inaccessible scales. Such advances may ultimately help bridge the longstanding divide between classical relativity and quantum mechanics, opening new pathways toward a unified understanding of fundamental physics.

Keywords: Gravitational waves, general relativity, compact binary mergers, laser interferometry, quantum gravity
