Black holes are enormous, physics-defying regions in the universe that continue to mystify laymen and scientists alike. Ever since the birth of Einstein’s theory of general relativity, researchers have mulled over the existence of these mysterious, invisible structures. Despite the voluminous body of research on the subject, it is still quite difficult to define what black holes really are.
In case you are looking for the answer, YouTuber morn1415 has created a brilliant animation on the size of these gigantic bodies. It uses a series of fascinating visual comparisons to give us some idea about how big a black hole actually is. To be able to make sense of this mind-scrambling video, you will need to know what Schwarzchild radius means. The term basically refers to the radius of a spherical object which, when crushed beyond that particular point, could turn into a black hole,
The Sun, for instance, needs to be compressed to approximately the size of a small town to become a black hole. In case of Earth, it is around the size of a small peanut. Among the known black holes in the universe is XTE JI650-500, which roughly resembles Manhattan in area and contains a mass equivalent to that of three to four Suns. Possessing the mass of over 1,000 compressed Suns, the M82 X-1 is a lot bigger than the former, and is about the size of the planet Mars.
If this is getting too much to grasp, don’t even try to visualize a supermassive black hole. Situated at the center of most galaxies, these objects are believed to contain the mass of nearly 20 billion Suns. How huge do you think they are?
