What is the mystery of black hole?

The story starts in the 1980s, when astronomers found that small (stellar-mass) black holes emit X-ray light that flickers in a curious pattern. At first, this flickering occurs every few seconds; however, the time between each flicker shortens over the course of a few months, eventually stopping completely.
This "quasi-periodic oscillation" (QPO) was thought to be a result of a phenomenon predicted by Albert Einstein's theory of general relativity — that any object with enough mass, like a black hole, will twist space-time as it spins. Later, scientists calculated that these gravitational vortices will cause the orbits of particles around the black hole to change orientation, leading to the QPO phenomenon.

"It is a bit like twisting a spoon in honey: Imagine that the honey is space, and anything embedded in the honey will be 'dragged' around by the twisting spoon," Adam Ingram, lead author of a new study describing the findings, said in a statement. "In reality, this means that anything orbiting a spinning object will have its motion affected," added Ingram, of the University of Amsterdam in the Netherlands.
Though the observed QPO periods were close to those predicted by this idea, there had not been enough evidence to nail down the connection — until n

it is said that black holes are formed when a highly dying star of immense energy collapse . it has such a tremendous gravitational pull that nothing could escape from it not even light and it is said that there r wormholes which connects two black holes which can act as time travels
