HISTORY OF BLACK HOLES

The theory of black holes was first proposed in the 18th century by John Michell and Pierre-Simon Laplace, further developed by the German astronomer named Karl Schwarzschild, in 1916, based on the general theory of relativity of Albert Einstein, and increasingly popularized by Stephen William Hawking.

Actually Black Hole comply with all the laws of physics, including gravity. In 1687, champion Isaac Newton showed that all objects in the universe are connected via gravity. However on earth, when compared to electricity, magnetism, energy impressed pressure or gravity is the weakest. But unlike the conditions in the Black Hole.

Newton's discovery has been refined by Einstein. He said through his theory of relativity that have a massive objects distort space and time capable of continuous, well is this distortion that we perceive as gravity. So in theory this could be an explanation for why gravity Black Hole  very large, to be able to suck the light.

All Black Hole identical, the difference is its mass, rotation about its axis, and the electric charge. The most remarkable of the Black Hole is when your spouse swallow an object (any object it is) then the characteristics of the object will be deleted.

Is Black Hole immortal ??  

Because no one can escape from the Black Hole, the Black Hole can not be destroyed, it is true. But apparently the Black Hole could die gan, with the passage of time then over time the Black Hole will evaporate back into the original energy and back into the universe. This theory was put forward by the famous physicist Stephen Hawking om in 1974 by using the laws of quantum mechanics.

Such as trying to calculate how much sand in all corners of the world, because the Black Hole were also countless. But the most important thing is no Black Hole that's close enough that harm the Earth (to date). The logic is like this, Black Hole is formed due to the explosion of supermassive stars, while in the Milky Way alone there are approximately 100 million supermassive star, could ente simpulin how tuh Black Hole there. It was still in the Milky Way, other galaxies yet. And to date there are only a dozen Black Hole detected from Earth, and the nearest one is 1600 years light. 

It is possible once a collision between Black Hole (in nature there are billions Black Hole gan), so they come closer together and no one can escape the gravity of each other, they will merge into a Black Hole. This combination will produce tremendous energy, and can cause ripples in space and time, called gravitational waves.
