Inside a Black Hole

As I descend through the spiral of hot gases spiraling the black hole, and experiencing time dilation due to the immense gravity near the event horizon, those may be the last things I see. Apart from being ripped apart and thus not being able to see anything, there is also a reason why there is seemingly nothing inside black holes, which is because there is only a singularity inside a black hole.

A singularity is a mass compressed in a volume so small that it would warp space-time into a “hole” straight through; according to the way gravity works, this means that no matter may escape (apart from using the theory of Hawking radiation, in which black holes very slowly radiate away its mass). Inside the singularity, matter will be ripped apart due to this extreme warping.

Past the event horizon, it seems that physics as we know it fail. As matter becomes ripped apart, it has no way of returning outside, which is why we cannot see anything inside. Inside the singularity, I expect to see everything the black hole has ever eaten. However, at this point they are indiscernible; “perfectly featureless”. Only the mass and the state of rotation the matter had before falling would be kept inside the singularity.

Of course, as the physics itself inside the black hole may be different, the singularity might not be what physicists expect it to be. Perhaps, according to another theory, we may see a parallel universe inside, or a different point in space-time, as the black hole may have a counterpart: the white hole, which spits matter out.

Either perfectly featureless, or if there is a whole other universe inside, with our current understanding, one thing is clear. We could only theorize what the inside of a black hole look like. Certainly it is very different from what we understand as space-time.
