BLACK HOLES

#Black-holes are produced by huge stars. They are called #BLACK-HOLES not because there are real holes in space but because thay cannot be seen as there is no light coming out of them.

When after burning for billions of years stars reach the end of their lives their energy dose not disappear.

The burning core becomes veru small like a pinpoint but its weight is as much as a star. It's also has tremendous gravity and this gravity pulls towards it everything that comes near.
