A strange case of a delayed eruption surprised astronomers. Supermassive black holes tear stars to pieces when they approach too closely. This is known as a tidal disruption event (TDE). The spewing out of material follows the destruction of the … Read More
Karl Schwarzchild proposed black holes in 1916 as a solution to Einstein’s field equations for his Theory of General Relativity. By the mid-twentieth century, astronomers were using indirect methods to detect black holes for the first time, observing their effects … Read More
Our Universe may be perfectly nested inside a black hole that is part of a larger Universe, like a cosmic Russian doll. In turn, all of the black holes discovered so far in our Universe—from microscopic to supermassive—could be ultimate … Read More
If you were to fall into a black hole (which we do not recommend), you”d likely find a singularity, or an infinitely small and dense point, at the center.“ That is what physicists have always believed. But now a pair … Read More
NASA has released a haunting audio clip of sound waves rippling out of a 250 million light-years-away supermassive black hole. The black hole is at the heart of the Perseus galaxy cluster, and the acoustic waves it emits have been … Read More
Our universe is so vast that it appears that nothing else could exist. Experts are beginning to suspect that our universe may be contained within a fourth-dimensional black hole. Our universe began as a singularity, an infinitely hot and dense … Read More
