Chinese researchers from the Shanghai Astronomical Observatory have claimed to have solid evidence confirming the “undeniable” existence of a gigantic black hole right at the center of our galaxy, the Milky Way.
Astronomer Zhi-Qiang Shen stated that they have detected signals in the form of radio waves emitted from the mysterious object Sagittarius A located at the heart of the Milky Way, indicating that this object is undoubtedly a supermassive black hole with a mass four million times greater than that of the Sun and a diameter 200 times that of the Sun.
Black holes are among the most enigmatic celestial objects in the universe, formed from the collapse of matter (for example, a star with a mass five times that of the Sun) and possess such immense gravitational force that not even light can escape. Consequently, detecting a black hole is often more challenging than finding a needle in a haystack.
However, scientists have noted that they can still “see” the black hole due to high-energy rays in the form of radio waves generated by atoms being pulled into the black hole, moving and colliding with each other at extremely high speeds.
