More than a century has passed since Albert Einstein published his general theory of relativity to refine Isaac Newton’s law of universal gravitation. Giving a description of gravity as a geometric property of space and time, or spacetime, this model is still used by scientists today. Einstein’s theory has important astrophysical implications, as it alludes to the existence of black holes – cosmic phenomena in which space and time are distorted in such a way that nothing, not even light, can escape.
But YouTube channel ‘SpaceRip’ revealed in its documentary “The most powerful black holes in the universe” as a discovery a few years later drew a lot of attention from scientists.
The narrator said: “Models suggest there could be as many as a billion black holes in our Milky Way alone.
“However, they are surpassed by a much larger and much more powerful presence hidden in the very core of the galaxy.
“The first suggestion of this presence came in 1932 – the telephone company Bell was concerned with static interference in what it saw as a revolutionary new technology – long-distance radio communications.
“The company tasked radio astronomer Karl Jansky with finding the sources.
“Using an unpleasant radio receiver, Jansky methodically scanned the broadcasts.”
The series detailed the bizarre discovery the scientist made.
It added: “He tracked most static to thunderstorms – some near, others far away.
“Then, on September 16, 1932, he made a noise, which he could not explain.

“In the 1960s, advanced radio telescopes began capturing signals from outer space.
“Observers called them like stellar radio sources – short for quasars.
“These bright blue beacons emitted much more energy than a star.
“Looking at their light spectra, researchers have realized that they are actually jets of super-hot gas that is speeding rapidly at hundreds of thousands of kilometers every second.”
And as technology progresses, experts will soon learn the true nature of the anomaly.
The series explained: “Just as the Hubble Space Telescope began its spectacular run, several new observatories were christened on the mountains in Hawaii in the north and the Andes.
“Finally in the spring of 2002, a star with the label S-2 approached, rapidly reaching a remarkable 18 million kilometers per hour.
“If its path near Sagittarius A were to appear erratic, astronomers would know that the galactic center is full of many massive objects.
“Instead its path was smooth. They concluded that S-2 and its companions must orbit around one object weighing several million times the mass of our Sun – a supermassive black hole. “
