Gravity waves are ripples in the fabric of space-time caused by the acceleration of massive objects, such as merging black holes or neutron stars. These waves travel at the speed of light and can stretch and compress space as they pass through it. Detected for the first time in 2015 by the LIGO observatory, gravity waves provide valuable insights into the universe's most violent events.
Unlike ocean waves, which occur on the surface of water, gravity waves are a fundamental aspect of Einstein's theory of general relativity. They help scientists understand the dynamics of cosmic phenomena and the nature of gravity itself, opening new avenues for astrophysical research.
