In the 1970s, physicist Stephen Hawking imagined a bizarre radiation emanating from the boundaries of black holes, meaning, among other things, that these objects are not as dark as we thought. A new study adds an essential element to this theory by developing a theoretical framework that will help scientists detect the light that escapes the black holes.
Although it is a beautiful idea, it has remained unconfirmed by observations. Physicists now suggest that we need to catch the black holes at the right time, just after two of them collide. Hawking radiation is the natural consequence of such an event.
Particles can also emerge from this space in pairs, striking one another, then disappear. At the edge of the black holes, it is believed that one of these two particles can escape the gravitational pull of the hole.
This is not a very bright phenomenon and it was only observed recently when it was noticed that the space around the black holes is bent.
What’s even more interesting is that black holes do not emit these Photons, but they collect particles. Thus, light does not have a set of features that would make its own black holes but is a reaction of black holes with the surrounding environment.
Recently, a team of Australian and Canadian researchers went on a different idea, suggesting a method for detecting the weak signals of this hypothetical radiation pattern. They choose to study the unique nature of the light produced by the photons that come out of the gravitational waves produced by the collision of two black holes.
In the second before the collision of the two bodies, they release a large amount of energy in the form of gravitational waves. It would be enough energy to spontaneously produce more photons out of nothing than usual. It would not be a spectacle of magnificent light, but it would be more than the photons almost impossible to observe mentioned before.
