The Black Hole

     Certainly we often hear the term black hole isn't it? Perhaps in the shadow of us it was the scary thing. But, do you know what that black holes? A black hole is a concentration of mass large enough to produce a very large gravitational force resulting in whatever is nearby sucked into it. The surface of a black hole is called the Event Horizon. The wall that had a small aperture when illuminated from a flashlight would light will penetrate into the side of the wall. However, a black hole is not the case. the light can only be entered into the hole but did not penetrate the hole. Because of this it is said to be "black". Black holes are also often referred to as an abyss of nothingness.

     Black holes are formed from the dead stars that have two times than our Sun.However, there are also saying that the great-grandson of a black hole is blue. It solidifies into a red star. After that it experienced a collapse of gravity and black holes eventually radiated. The density of black holes can be billions of times more densely in the appeal of our Sun.
