What is the difference between a black hole and a stellar black hole? Supermassive black holes are ENORMOUS, and can stretch for nearly 2 billion miles! Stellar black holes however, are much smaller and stretch around 20-100 miles across. They roam...
What makes a stellar remnant a black hole? If the core left behind after a supernova is massive enough (probably about two or three times the mass of the sun), even the star’s neutrons aren’t strong enough to resist the force...
Are there stellar black holes in the Milky Way? The stellar-mass black hole is likely one of 100 million solitary black holes in the Milky Way, scientists said. A rogue black hole wandering the space lanes of our Milky Way galaxy...
Are Stellar black holes small? Stellar black holes — small but deadly Black holes formed by the collapse of individual stars are relatively small but incredibly dense. One of these objects packs more than three times the mass of the sun...
What makes an intermediate black hole? An intermediate-mass black hole (IMBH) is a class of black hole with mass in the range 102–105 solar masses: significantly more than stellar black holes but less than the 105–109 solar mass supermassive black holes....
How many stellar black holes are there in the universe? Most galaxies, and maybe all of them, harbor such a black hole. So in our region of the Universe, there are some 100 billion supermassive black holes. The nearest one resides...
Did a black hole create the Big Bang? Accordingly, the Big Bang was a nonsingular Big Bounce at which the universe had a finite, minimum scale factor. Or, the Big Bang was a supermassive white hole that was the result of...
What is dark matter mostly made of? Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), are believed to have ten to a hundred times the mass of a proton, but...
How does a black hole created? How Do Black Holes Form? Primordial black holes are thought to have formed in the early universe, soon after the big bang. Stellar black holes form when the center of a very massive star collapses...
Is dark energy a form of dark matter? And what’s the difference between dark energy and dark matter? In short, dark matter slows down the expansion of the universe, while dark energy speeds it up. Dark matter works like an attractive...
