Black holes are a class of astronomical objects that have undergone gravitational collapse, leaving behind spheroidal regions of space from which nothing can escape, not even light. Observational evidence indicates that almost every large galaxy has a super massive black hole at its center. An immense event horizon with the Schwarzschild diameter of 590.5 billion kilometres (3,900 astronomical units), assuming if it is a non-rotating black hole, 100 times the distance from the Sun to Pluto . a circumference that would take 71 days and 14 hours to travel at light speed. The idea was ridiculed at first, but other scientists calculated that the star continues forever to fall inward toward its center—thus creating what we called a black hole. Black holes can grow more massive over time as they “eat” gas, stars, planets and even other black holes. Meet your neighborhood super massive black hole, Sagittarius A*. This is the black hole at the heart of the Milky Way, 4 million times more massive than the sun. But it's not as close as you might think and estimated its distance at 26,000 light-years from Earth. Mahakala is typically visualised as black in colour. Just as all colours are absorbed and dissolved into black, all names and forms are said to merge into Mahakala symbolising his all-encompassing nature. Black can also represent total stillness or the complete absence of light, much like a black hole.
Rig Veda calls a black hole, graha a cavern-like lightless dark and deep place. Cavern means a large, dark place. Rig Veda also calls it a patra, meaning a vessel! This is where Soma is created and confined. Ton 618 is the largest black hole known. The largest black hole ever found in the known universe is found in Ton 618. This is a hyper luminous Lyman-alpha blob that has a black hole that measures 6.6×1010 solar masses. It has a mass that equals about 66 billion times that of the Sun. Four years ago, astronomers released the first ever image of a black hole: a reddish, puffy doughnut of light surrounding an empty, dark hole in the center of the giant galaxy M87, which lies 55 million light-years away in the constellation Virgo. The super massive black hole, discovered by JWST, has a mass 10 times that of our Sun, according to Space.com. What's astonishing is this is the oldest black hole that has ever been discovered in the universe, at the center of a galaxy just 570 million years after the universe began. Such a high mass makes it one of the most massive black holes known in the universe. A black hole of this mass has: 24,100 times the mass of the black hole at the center of the Milky Way twice the mass of the Triangulum Galaxy, including its dark matter halo.
