Introduction of Gravitational Waves

The discovery of the massive star SN 2006gy, which led to the creation of gravitational waves, marking the largest stellar explosion known. These waves, emanating from the star, travel through space time, a concept predicted by Einstein a century ago. Gravitational waves are distortions in the fabric of space-time caused by mass in motion, propagating outward like a signal.
