Gravitational Waves
Gravitational waves are ripples in the fabric of spacetime caused by some of the most violent and energetic processes in the universe, such as the collision of black holes or neutron stars. These disturbances propagate as waves, travelling outward from their source at the speed of light, carrying with them information about their cataclysmic origins and providing a unique glimpse into the inner workings of these extreme events. In the context of high energy physics, gravitational waves serve as an invaluable tool for probing the nature of gravity and the structure of spacetime itself, allowing researchers to test the predictions of general relativity and explore new frontiers in our understanding of the cosmos.
