FIRST STAR ESCAPED TO MILKY WAY'S BLACK HOLE -  S5-HVS1 Black hole is the one of the giant in space. Even fastest thing can not escaped from it's  gravitational force. Gravitational force is the weakest force among all four forces but black hole shows it's still too strong . Black hole is so dense point in the  4 dimensional  space -time which has tremendous mass in single point. According to scientist ,black holes plays important role in formation of galaxies. Every galaxy has one massive black hole at it's  center. The stars in vicinity of black holes revolve around black hole with elliptical path. Even our MILKY WAY also has Saggiritus a.  Sagittarius A  is so massive black hole but still S5-HVS1 manage to escape from it's gravitational pull.  The gravitational pull of these behemoths is so enormous that not even light can escape – which is why we can’t just look into the night sky and ‘see’ one. Now scientists have discovered a star which was lu

Through the wormhole Science fiction is filled with tales of traveling through wormholes. But the reality of such travel is more complicated, and not just because we've yet to spot one. The first problem is size. Primordial wormholes are predicted to exist on microscopic levels, about 10–33 centimeters. However, as the universe expands, it is possible that some may have been stretched to larger sizes. Another problem comes from stability. The predicted Einstein-Rosen wormholes would be useless for travel because they collapse quickly. "You would need some very exotic type of matter in order to stabilize a wormhole," said Hsu, "and it's not clear whether such matter exists in the universe." But more recent research found that a wormhole containing "exotic" matter could stay open and unchanging for longer periods of time. Exotic matter, which should not be confused with dark matter or antimatter, contains negative energy density and a la

WORM HOLE ARE TIME TRAVELING MACHINES A  wormhole  is a sort of tunnel that joins distant points in space, or even two universes, via space-time curvature. Theoretically, such a tunnel could be traversed from one point in space to another without actually traveling the distance between them.  In the 1980's, Thorne, who is the Feynman Professor of Theoretical Physics, Emeritus, at the California institute of Technology, kicked off a serious discussion among physicists about whether or not an object (like a spaceship) could physically travel through a wormhole. In other words, do the laws of physics forbid it? Or, with unlimited resources and knowledge, could a civilization build a wormhole ? Physicists, including Thorne, have made some progress on this question. Scientists knew prior to the 1980s that if wormholes existed, they would evaporate before anything (even light) could pass from one opening to another. So sending something through a worm
