A long-standing question in astrophysics is: how and when did supermassive black holes appear and grow in the early universe? New research using NASA's Chandra X-ray Observatory and the Sloan Digital Sky Survey (SDSS) suggests that an answer to this question lies with the intermittent way giant black holes may consume material in the first billion years after the Big Ban
The astronomers from the University of Texas at Austin and Harvard University test the basic principles of event horizon to seek whether the matter completely vanishes into the supermassive black hole.
When it comes to high-speed collisions, nobody here on Earth has anything on black holes. Astronomers have witnessed a new first: two high-speed knots of matter colliding in a sort of rear-end impact. They saw this after creating a time-lapse video of a super-speed jet of plasma as it shot out of a supermassive black hole. The knots of matter were inside the black hole until it blasted them out-and into each other.
Imagine winning the Powerball jackpot-more than once. You may have a sense of how a team of astronomers feels after their discovery of a set of four quasars at the visible universe's edge. These brilliant beacons of light are typically spread far apart, but this quartet exists shoved together in only 650,000 light-years of space-equivalent to around a quarter of the distance between our closest big neighbor galaxy Andromeda and the Milky Way.
Every science fiction fan is familiar with the notion of parallel universes with the Star Trek series being one of the first to popularize the notion. However, thanks to the Large Hadron Collider, we may soon have proof that a parallel universe does, in fact, exist.
