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. ![]() The main block that comes from the 2nd law of thermodynamics: “the state of entropy of the entire universe, as an isolated system, will always increase over time”.This article is co-written by Elias El Hachem and Elio Gereige White holes are a cosmic phenomenon that can be explained theoretically and mathematically, but they just don’t fit what we know of reality, yet. ![]() Others have posited that the big bang happened from a white hole and an absurd amount of matter and energy were ejected from it. Some believe that white holes are what black holes become after they have completely evaporated, which can take trillions of years. And since we have never really proved their existence, many theories about white holes are just speculation. In reality, it is highly unlikely that white holes are just the other end of black holes. They are called wormholes or Einstein-Rosen bridges. In many science-fiction stories, white holes are used as a way to travel through time or to other parts of the universe. They are supposedly the “opposite” of black holes: regions of space where matter can exit, but nothing can enter. White holes are hypothetical objects we have never seen one. We don’t know what’s on the other side of a black hole, nor if there is one.If you fell into a black hole, you would die by spaghettification.There are four types of black holes: stellar, intermediate, supermassive, and micro.Colliding black holes generate an incredible amount of energy in the form of gravitational waves that propagate through space-time.Two black holes can merge to form an even bigger black hole.Black holes can swallow anything that gets too close to them, including moons, planets and entire stars.It is located about 1,500 light-years away from us. The closest black hole to Earth is called “The Unicorn”. ![]() One out of every thousand stars is massive enough to become a black hole. ![]() The first image of a black hole was captured in 2019.The first black hole, Cygnus X-1, was discovered in 1964.Albert Einstein first predicted the existence of black holes in 1916.Our own milky way could host over 100 million black holes.For example, if you were to fall into a black hole, time would slow down for you. It’s impossible to directly observe a black hole.
