Gravitomagnetism: We may not need dark matter after all
Dark matter may not exist. Instead a phenomenon predicted known as Gravitomagnetism could explain the high rotation curves of galaxies.
Gravitational waves turn dark matter into black holes as the universe dies
Physicists found that dark matter halos will eventually collapse into black holes as they leak energy through to gravitational waves.
Black hole gruesomely rips apart star in another galaxy
Astronomers have detected a radio emission in another galaxy from an accretion disk caused by a black hole tearing apart a star.
Can Dark Energy be studied using Gravitational Waves?
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 […]
