For the amount of ten times the Sun , his death is much more dramatic . Ejected its outer layers into space in a supernova explosion . Meanwhile , the core compressed by gravity into a neutron star , spinning ball with a diameter of about 20 kilometers . Fractions of a sugar cube of neutron star weighs a billion tons on Earth ; neutron star 's gravitational pull is so great , so if there is candy falls there , that the impact would produce energy for atomic bombs .
But this is nothing compared sakratulmaut star whose mass is 20 times that of the Sun. If the atomic bomb at Hiroshima was detonated every millisecond during the age of the universe , it is still far less than the amount of energy released in the last moments of the collapse of a giant star . The core was plunged into . The temperature reached 55 billion degrees Celsius . Powerful gravitational force , unstoppable . Blocks of iron greater than Mount Everest solidified instantly become as small as grains of sand . Scattered atoms into electrons , protons , neutrons . Small objects were crushed into quarks , leptons , and gluons . And so , more and more smaller , more dense , until ...
Until somehow . When trying to explain this important phenomenon , two main theories that govern the workings of the universe of general relativity and quantum mechanics - mess , like a needle indicator aircraft circling spiral wildly when the plane crashed .
The star becomes a black hole .
What makes the darkest abyss of black holes in the universe is the speed needed to escape its gravitational pull . To overcome the grip of the Earth , we should reach 11 kilometers per second . This fast - six times the speed of a bullet - but man-made rockets have achieved this speed since 1959 . Universal speed limit of 299,792 miles per second , the speed of light . However , it was not enough to overcome the pull of the black hole .( see also: lomba burung cendet )
So , whatever is in a black hole , even light beam , can not come out . And the strange effects of extreme gravity , we may not be able to peek inside . Dividing line between inside and outside the black hole called the ' event horizon ' . Anything past the horizon that the stars , planets , human - lost forever .
