Hello @guys!!
============
Black Hole
°°°°°°°°°°°°°°°°°
Invisible source of X-ray signals of enormous power, such as excit in large numbers in our own and neighbouring galaxies. They are formed when the thermo-- nuclear fires of a giant star burn out,and it shrinks virtually crushed into annihilation by the momentum of its own gases drawn towards its centre of gravity-- until its atoms are so close together that a spoonful weighs millions of tons. Its escape velocity becomes so great that it exceeds the speed of light.Anything approaching it is, therefore, sucked in and never seen again,and time is distorted by being stretched out so that a second lasts a billion years.
