What’s Inside a Black Hole 

Have you ever heard of something that obliterates the laws of physics?

Black holes are one of the only things that scientists have not fully investigated. Black holes shred anything that gets near its horizon, not even light can escape it.

First of all, what is a black hole? We first know that as you approach the black hole’s event horizon, comes the dreaded point of no return. In longer terms, “A black hole is a tremendous amount of matter crammed into a very small, in fact, zero amount of space. The result is a powerful gravitational pull, from which not even light can escape and, therefore, we have no information or insight as to what life is like inside.” https://www.discovermagazine.com/the-sciences/what-happens-in-a-black-hole . Understanding what a black hole is, is just as important as understanding how a black hole forms. A black hole forms when a supernova explosion occurs. When this explosion occurs, the remnants of a large star is what forms the black hole.  

 The reason its been known that black hole’s form when a massive star dies, is because of Albert Einstein’s general theory of relativity which is” what we perceive as the force of gravity arises from the curvature of space and time”. It was thought to have predicted them by linking space-time with the action of gravity and although we “technically” do not know what happens in a black hole, scientists have still predicted what is happening.  

On the outside of a black hole, something called spaghettification occurs. “As objects and material are drawn into a black hole, they’ll undergo a process evocatively called spaghettification. This is because gravity is so extreme and increasing so rapidly as you approach the black hole that your head and feet would experience drastically different gravitational environments. You would be physically stretched out, and your sense of time would slow to a crawl in the brief moments before you fell into the singularity, the zero-point of the black hole itself.” https://www.discovermagazine.com/the-sciences/what-happens-in-a-black-hole

A gravitational singularity (also called a space-time singularity) occurs when the quantities used to measure the gravitational field become infinite in a way that is independent of the coordinate system. To put it another way, it’s a point at which all physical laws are indistinguishable from one another, where time and space are no longer intertwined realities, but merge almost indistinguishably and lose their separate meaning. 

Some scientists actually believe that black holes could be wormholes to other dimensions. As shown in a new theory, a black hole is essentially a wormhole that connects universes. According to the theory, the matter attracted by the black hole does not collapse into a single point as predicted, but instead gushes out a “white hole” at the other end of the black one. According to the big bang theory, the universe began as a singularity. However, scientists are baffled as to how such a singularity could have formed in the first place.

With limited information, no one knows which theory to believe.

 In this photo, you can see that anything getting pulled in is “spaghettifying” whilst going into the black hole. In order to help understand black holes a bit better, here is a video. 

 I believe that we will never know what goes on inside a black hole. Although, based on the research we have, i agree with the fact that there is a possible “other dimension” through a black hole.
