The secrets and mysteries of black holes - MSN

WebIf a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star … Yes. The late physicist Stephen Hawking proposed that while black holes get bigger by eating material, they also slowly shrink because they are losing tiny amounts of energy called "Hawking radiation." Hawking radiation occurs because empty space, or the vacuum, is not really empty. It is actually a sea of particles … See more A stellar-mass black hole, with a mass of tens of times the mass of the Sun, can likely form in seconds, after the collapse of a massive star. … See more The research involves looking at the motions of stars in the centers of galaxies. These motions imply a dark, massive body whose mass can be … See more It certainly wouldn't be good! But what we know about the interior of black holes comes from Albert Einstein's General Theory of Relativity. For black holes, distant observers will only see regions outside the event … See more No. There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for … See more WebWhen falling towards a black hole, for example, an object is stretched in the direction of the black hole (and compressed perpendicular to it as it falls). In effect, the object can be distorted into a long, thin version of its undistorted shape, as … development length aci
