An artists illustration of what scientists think is happening inside black hole

Scientists have been wondering about black hole since long. Many of us get fascinated by the idea of  a black hole which revolves very near to a planet and mass from that planet keep falling into black hole. That's how planet collapses going into black hole. This thought or imagination may seem but terrifying but actually what scientists have discovered is quite similar to it.

This same black hole Cygnus X-1 was discovered in 1964 and in 1970 Stephen Hawking bet his companions that X-1 is not a black hole. In 1990 Stephen Hawking admitted that he was wrong.Recently NASA has got more accurate data about black hole.

NASA astronomers have precisely determined the spin, mass and distance of Cygnus X-1 and they are more confidently calling it a black hole.
