GW detection

Gravitational Wave (GW) detection refers to the discovery of ripples in spacetime caused by massive, accelerating objects, like merging black holes or neutron stars. These waves were predicted by Albert Einstein's theory of general relativity. Specialized instruments, like LIGO and Virgo, use laser beams and mirrors to sense minuscule changes in distance caused by passing gravitational waves. Detecting these waves provides insights into the universe's most violent events, enhancing our understanding of astrophysics and the nature of gravity. It represents a significant advancement in observational astronomy, complementing traditional methods like light observations.
