It was Stephen Hawking who in 1974 predicted that black holes can evaporate entirely. For the first time, physicists confirm this prediction.
Professor Hawking suggested black holes are not perfectly black and they actually emit particles.
According to Hawking this radiation could in the long run siphon sufficient mass and energy far from black holes to cause them to vanish. The hypothesis was once seen as impossible to be proven but is now broadly thought to be valid.

The Hawking radiation is too faint for our instruments to detect it in space. But scientists have seen this radiation in a black hole analog utilizing sound waves and probably the strangest, coldest matter known to man.
As we all know by now, the gravitational force of a black hole is so strong that even light can’t escape.
Even though the vacuum of space is generally believed to be empty, quantum mechanics states that a vacuum is full of virtual particles that fly in and out of existence in matter-antimatter pairs. Particles of antimatter have a similar mass as their issue partners, but opposite electrical charge.
Usually, when a pair of virtual particles pop out, they immediately decimate each other. However, near a black hole, the massive gravitational forces will pull the particles apart. Therefore, absorbing one into the black hole and shooting the other off into space.
The absorbed particle has a negative energy, which reduces the black hole’s energy and mass. So, if a black hole swallows enough of such particles it eventually evaporates. The escaping particle becomes known as Hawking radiation.
