Gravity Waves are ripples in spacetime caused by massive accelerating objects like merging black holes. These waves carry energy across the universe, offering a new way to observe celestial events.

Gravity Waves can be detected using advanced interferometers like LIGO. Their discovery confirmed Einstein's theory of general relativity and opened a new window into studying the cosmos.

Gravity Waves are crucial for understanding the universe's fundamental forces. They provide direct evidence of events that were previously only theorized, enhancing our grasp of astrophysics and cosmology.
