An astronomer has proposed a method for deflecting asteroids away from Earth with missiles to stop the next mass extinction.
Dark matter may not exist. Instead a phenomenon predicted known as Gravitomagnetism could explain the high rotation curves of galaxies.
Physicists found that dark matter halos will eventually collapse into black holes as they leak energy through to gravitational waves.
Astronomers have detected a radio emission in another galaxy from an accretion disk caused by a black hole tearing apart a star.
Introduction Before talking about dark energy, we need to talk about gravitational waves. In his theory of General Relativity, Albert Einstein predicted the existence of gravitational waves. Since then, astronomers have recognized the usefulness it provides for humanity to understand the universe in new ways. Much like what radio astronomy did in the 1930s. With […]
