Most of the universe may be trapped inside of ancient black holes

In case you haven't heard, there is a very, very big problem with the universe: About 80% of all of the stuff inside it is missing.<p>Astronomers call this material "dark matter." They know it's out there because its huge mass tugs on and shapes galaxies, but no one has ever detected the material …

Monstrous Cosmic Gas Cloud Set To Ignite The Milky Way

When we think about our galaxy, most people think about the stars in the sky, the grand, sweeping spiral arms, the disk-like plane of our Milky Way filled with dust, and the bulge in the galactic center. All of this combines to make up our run-of-the-mill home, complete with some 400 billion stars …
