There must be a singularity at each black hole’s center

The more mass you place into a small volume of space, the stronger the gravitational pull gets. According to Einstein’s general theory of relativity, there’s an astrophysical limit to how dense something can get and still remain a macroscopic, three-dimensional object. Exceed that critical value, and you’re destined to become a black hole: a region of space where gravitation is so strong that you create an event horizon, and a region from within which nothing can escape. No matter how fast you move, how quickly you accelerate, or even if you move at the ultimate speed limit of the Universe — the speed of light — you can’t get out. People have often wondered whether there might be a stable form of ultra-dense matter inside that event horizon that will hold up against gravitational collapse, and whether a singularity is truly inevitable. It’s a reasonable thing to wonder, as we simply cannot access the region interior to the event horizon; we cannot know the answer directly. <a href="https://medium.com/starts-with-a-bang/there-must-be-a-singularity-at-each-black-holes-center-b7211b743c99">Click Here</a>
