Web12 de jul. de 2024 · The current cosmological model only works by postulating the existence of dark matter – a substance that has never been detected, but that is supposed to constitute 75% of the universe. But a simple test suggests that dark matter does not in fact exist. If it did, we would expect lighter galaxies orbiting heavier ones to be slowed down … 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 hole to make a … Ver mais 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. The matter that falls into a black hole adds … Ver mais 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 eating the whole … Ver mais 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 dwarf. But if, hypothetically, the Sun suddenly became a black hole … Ver mais 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 … Ver mais
