How to detect cosmic black holes

The cosmic black hole is an area of ​​space with extremely strong gravitational force, nothing can escape when approaching them, including light at a speed of 300,000 km / sec.

The black hole is called "black" because it absorbs all radiation and sucked matter through the event horizon.

Scientists know the black hole through X-Chandra observatory . In fact, it is impossible to observe the black hole, but through the surrounding phenomena, the space of the black hole passing through, swirling the stars and the cloud of gas, swirling into the endless space.

The stars and nearby objects then heat up millions of degrees, emitting X-rays. According to Einstein's theory of relativity, gravity can bend space, the space of the black hole passing through will create bending images. Curved on the telescope. Based on the recorded image, astronomers locate the black hole.

Observations show that many black holes exist, even if they appear earlier than the birth of stars and galaxies.
