White holes, which are theoretically exact opposites of black holes, could constitute major portion of mysterious dark matter that's thought to make up most of matter in Universe, new study finds. And some of these bizarre white holes may even predate Big Bang, researchers say. Black holes possess gravitational pulls so powerful that not even light, fastest thing in Universe, can escape them. Invisible Spherical Boundary Surrounding Core Of Black Hole That Marks Its Point Of No Return Is Known As Its Event Horizon. Black Hole Is One Prediction Of Einstein's Theory Of General Relativity. Another is known as white hole, which is like black hole in reverse: Whereas nothing can escape from black hole's event horizon, nothing can enter white hole's event horizon. Previous research has suggested that black holes and white holes are connect, with matter and energy falling into black hole potentially emerging from white hole either somewhere else in cosmos or in another Universe entirely. In 2014, Carlo Rovelli, theoretical physicist at Aix - Marseille University in France, and his colleagues suggested that black holes and white holes might be connected in another way: black holes die, they could become white holes. In 1970s, theoretical physicist Stephen Hawking calculated that all black holes should evaporate mass by emitting radiation. Black holes lose more mass than they gain are expected to shrink and ultimately vanish. However, Rovelli and his colleagues suggest that shrinking black holes could not disappear if fabric of space and time were quantums that is, made of indivisible quantities know as quanta. Space - time is quantum in research that seeks to unite general relativity, which can explain nature of Gravity, with quantum mechanics, which can describe behavior of all known particles, into single theory that can explain all forces of Universe. In 2014 study, Rovelli and his team suggest that, once black hole evaporates to degree where it could not shrink any further because space - time could not be squeezed into anything smaller, dying black hole would then rebound to form white hole. We stumble on fact that black hole becomes white hole at end of its evaporation, Rovelli tells space. Com. Black holes nowadays are thought to form when massive stars die in giant explosions know as supernovas, which compress their corpses into infinitely dense points know as singularities at hearts of black holes. Rovelli and his colleagues previously estimated that it would take black hole with mass equal to that of Sun about quadrillion times current age of Universe to convert into white hole. However, prior work in 1960s and 1970s suggested that black holes also could have originated within second after Big Bang, due to random fluctuations of density in hot, rapidly expanding newborn Universe.

Twin no mans lands

Einstein's field equations hit physics like tsunami in 1915, and theorists are still sorting through wreckage. Beyond describing force of gravity, his hypotheses also bring paradigm - shattering message about nature of reality. More than rigid backdrop, space and time bend and fold along with mass of stars and planets. That insight sparked race to calculate just how much abuse space could take from matter that drifts through it. Within year, physicist and astronomer Karl Schwarzschild found first exact solution to Einstein's equations, calculating how space - time curves around single ball of mass. In his answer, lay seeds of what physicists today call singularity spherical mass shrink down to infinitely dense point, wrapping space around it so tightly that region pinches off from rest of universe. It form no man's land whose event fracture link between cause and effect. Black holes, most singularities, are regions of space so warped that no exits exist. Outside universe can influence inside of Black Hole's horizon, but interior can't affect exterior. When mathematician Martin David Kruskal extended Schwarzchild's black Hole description in 1960 to all domains of space and time, his new picture contained reflection of black Hole singularity, although he didn't realize its significance at time. Later, as black holes enter vernacular, natural terms emerge for their theoretical twins. It took 40 years understand black holes, and it's only recently that people have been focusing on white holes, Rovelli say.

Why white holes don't exist

As with all things cosmic and hole - y, white holes trace their origins to Albert Einstein's general of relativity. Some solutions of theorys complex equations produce black holes and, it turns out, other produce white holes. Two are, mathematically least, equally likely to exist. Further, black holes and holes are as intertwined as names suggest. Nasa astrophysicists have referred to latter as time - inverse of black holes. Reverse film footage of black hole, in other words, and youll get white hole and vice versa. Great, but what that actually mean? Some interpretations are fairly literal. White holes may simply be opposite end of holes, connected by theoretical tunnels of space - time called wormholes. So matter and energy falling into black hole would eventually beam out of white hole, somewhere in this or another universe. But do go rushing into black hole just yet, hoping for free vacation to distant land: crushing gravity would ensure that only mangled and broken down version of you and your luggage would make it out of white hole on other side.
