THE UNIVERSE WAVES HELLO

The video discusses the groundbreaking detection of gravitational waves, a major prediction of Einstein's theory of general relativity. It explains the nature of these waves as ripples in spacetime caused by massive cosmic events, such as black hole collisions. The video highlights the role of LIGO, a highly precise observatory, in detecting these waves and the significance of this discovery in opening new avenues for understanding the universe. The detection of waves from a black hole collision 1.3 billion years ago marks a new era in astrophysics, akin to Galileo's first use of the telescope.

Explain how LIGO measures gravitational waves.
