WebMay 19, 2016 · The more massive an object you put on the sheet the deeper it sinks. This sinking effect distorts the grid lines so they are no longer straight, but curved. The deeper the well you make in space, the more space distorts and curves. And the deepest of wells are made by black holes. 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 stellar remnants called neutron stars. A neutron star can also merge with a black … 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 … 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, … 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 … See more The Sun will never turn into a black hole because it is not massive enough to explode. Instead, the Sun will become a dense stellar remnant called a white … See more
