When two oversized black holes in orbit approach each other, the result is quite "dancing". NASA has released a video showing two black holes dancing "tango". This is an impressive spectacle that can be seen in the video of the simulation of a merger between two greats of black holes. Black holes are the most mysterious cosmic bodies, so deciphering their function, their mechanisms and the phenomena they produce can answer scientists' questions about every aspect of the universe.
The rapid technological progress of the last decades has enabled a more in-depth study of black holes. We now have information about how they behave both with each other and with stars or cosmic matter.
However, scientists do not yet have much information about what can happen when two large black holes are involved in a collision process. We know that basically such a collision results in a merger where a new even larger black hole is eventually formed. But the phenomena produced in this process have not yet been perceived and understood by them scientists.
The impressive video released by NASA shows a simulation of the merger of two black holes. THE a black hole has a mass about 200 million times that of the Sun and is surrounded by red hot gas rings called incremental disks. In its orbit is one second black hole weighing about half that mass, and the gas and dust rings are shown in bright blue.
As shown in the simulation, this is not a violent process, but develops a kind of cosmic dance, where one approaches the other and then moves away, causing each time various phenomena. Based on this simulation, scientists receive important information about what can happen when two black holes merge, and what is the cause and meaning of the data that reach us observing such a phenomenon.
One of the phenomena that the simulation shows to be produced by the merger is that of the so-called gravitational lens. It is a phenomenon of light curvature, in which the light of a cosmic body closest to the observer - a star or galaxy - acts as a magnifying glass, allowing it to see another cosmic body "hidden" behind them at a much greater distance.
The simulation also reveals gravitational forces and phenomena developed during this merger, providing new valuable data to scientists. But even for the non-experts, watching this process is definitely a very interesting and impressive spectacle.
