Stellar-mass black holes are left behind when a massive star explodes. These explosions distribute elements such as carbon, nitrogen and oxygen that are necessary for life into space. Mergers between two neutron stars, two black holes, or a neutron star and black hole, similarly spread heavy elements … 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. These relatively small black holes can also be made through the merger of two dense … 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 computed from the speeds of the stars. … 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 … See more WebFeb 21, 2024 · A black hole is extremely dense. The edges are thought to be less so but the core is believed to be infinitely dense. “It appears black because its gravitational pull is so strong that not even light can escape,” says Leah Tolby from Kids Astronomy.
Scientists measure gravity at the edge of a black hole for …
WebBlack holes are some of the most fascinating and mind-bending objects in the cosmos. The very thing that characterizes a black hole also makes it hard to study: its intense gravity. All the mass in a black hole is concentrated in a tiny region, surrounded by a boundary called the “event horizon”. Nothing that crosses that boundary can return to the outside … WebWe have created a website, called ”Black Holes: Gravity’s Relentless Pull”, which explains the physics and astronomy of black holes for a general audience.
