![]() To anticipate your question, Yes, scientists were able to locate the Black Hole at the center of our Galaxy, the Milky Way, after several years of studies and research. These Black Holes are the result of the combination of several intermediate Black Holes. The most fascinating one is the supermassive, which is usually located at the center of nearly every Galaxy. Technically, there are three types of Black Holes: stellar, supermassive and intermediate Black Holes. The residue consists of a super dense object of subatomic particles and a neutron star (around 16 km in diameter) is formed, whose mass is one Million times greater than the mass of Planet Earth: That’s the birth of our Black Hole. ![]() Then, the star implodes under the effect of its own weight and projects a shock wave, exploding into what is called a Supernova. So to elaborate a bit, when their life comes to an end, the gravitational collapse at the heart of those red supergiants raises the temperature to reach 100 of millions of Kelvins, causing helium and carbon to merge and form heavier elements like oxygen, silicon and sulfur. These stars would collapse under their own gravity, causing them to either die in peace, or contract into an infinitesimal point of extremely large density, forming a Black Hole. In general, stars would resist their own massive gravities, by a combination of nuclear processes, until eventually they run out of fuel. Things are starting to look interesting! But, how exactly are Black Holes formed?īlack Holes are the descendants of stars - supergiant red stars - 10 times more massive than our Sun, but whose lifespan represents only a fraction of the life of ordinary stars. But the most simple and effective definition, away from physics and mathematics, describes a Black Hole as “a region in space where the gravitational field is so intense that light bends”. Some scientists define it as a state of infinite density, a concept that our brain cannot clearly understand, while others refer to it as “a region where the fabric of space-time closes on itself”. So, in brief, a Black Hole is a “monstrous mystery”. From there, many physicists and cosmologists, notably John Wheeler (who renamed Black Holes from “Frozen Stars”) and Stephen Hawking, took Black Holes more seriously and It wasn’t until 55 years after the first mathematical solution, to be precise in 1971, that the first Black Hole was actually discovered.Įnough history, let’s dig deeper into more captivating stuff. It wasn’t however until 1915-1916, when Albert Einstein came up with his theory of General Relativity, and astronomer Karl Schwarzschild solved some tricky equations, that Black Holes started to get into mathematical forms, therefore real science. Few years later, French famous intellect Laplace independently described the same phenomena of massive stars absorbing light particles, calling such objects “Dark Bodies”. The initial hypothesis of the existence of Black Holes, or “Dark Stars” as how it was referenced back then, dates to the 18th century, when professor John Michell reasoned that, since light might be made of particles (based on Sir Isaac Newton’s hypothesis), then a really massive star could have a gravity so strong that even light particles couldn’t escape it, rendering the star invisible to astronomers, hence the name “Dark Stars”. But, what exactly are Black Holes? To start, let’s delve into some brief history first: We’re pretty sure most of you have already heard of Black Holes, those mysterious dark monsters which absorb everything in their perimeter, so that even light cannot escape. So, what are Black Holes? How are they different from White Holes? Buckle up, since we’re going to answer these questions in layman’s terms, in this interesting article! What are Black Holes? ![]() And to keep things balanced, just like the Yin and the Yang, White Holes “might” exist too, mathematically proven but not yet observed. The Universe is merely a vast work of art consisting of tremendous mind-blowing entities, among which are Black Holes. This article is co-written by Elias El Hachem and Elio Gereige
