Often, people think of black hole as an actual hole that appears to be black. I’ve always wondered about how that would work. However, after years and years of research (school projects), I learned that black holes are actually a singularity (point of great mass where everything is clumped together), pulling in everything around them with gravity. As the saying goes, “nothing escapes it, not even light.” So what makes it so dense? A black hole is formed by a gigantic star (supernova) collapsing in on itself from the gravity. So something maybe billions and trillions times the mass of our sun, would be shrunk to the size of the head of a needle; that’s what creates the immense gravity. Black holes can only be formed by supernovas (a giant star) because it’s the only type of star that has enough mass to provide the mass that a blackhole needs to form. Any smaller, and the result would be a dwarf. Many smaller stars, when dying, would collapse into white dwarves, brown dwarves, or red dwarves pulled together by the gravity, and forming into a dense sphere. A supernova (a giant star) does the same. Except the sphere is way smaller. And way denser. And has a way stronger gravity. And way deadlier (Stay tuned for explanation). Resulting in the black hole. Since the mass is so concentrated, its gravity would be unbelievable, too.

Imagine this: on an unbreakable gigantic pillow, there is one grain of rice; the surface would sink in a slight bit, that would be the mass of the earth. Then a half inch metal ball would be put down, and the dent would be slightly bigger compared to the rice, that would be the sun. But compared to a bowling ball, the metal ball would be nothing, there would be a huge dent, and that’s a supernova. Now back to the grain of rice.  If you divide that grain of rice by two, by five, by ten, or even a thousand, and put your weight into the fraction of a grain of rice, that would be the black hole. The entire pillow would concave. The pillow is the fabric of time and space. And the more it sinks, the greater the gravity there. At some point, light (contrary to popular belief, does have a very slight mass), will fall into the pull of its gravity too. The video attached to the bottom would provide a visual explanation.

Here’s an interesting video that gives a visual representation of my pillow example:
