Gravitational Waves Could Come From the Cocoons of Dying Stars
Astronomers have recently made an exciting discovery about dying stars: they can act as a source of gravitational waves. After studying the cocoons of these dying stars, researchers have found that the stars can act as a powerful source of gravitational waves. Gravitational waves are ripples in space-time that are created when two massive objects interact. By studying these cocoons, scientists can better understand the physics of how gravitational waves are created and how they propagate through the universe. This is an important step in furthering our understanding of the universe.
