What happens to the matter that falls into the black hole

When matter falls into a black hole, it undergoes a series of changes as it approaches and eventually crosses the event horizon, the point of no return. Here's what happens to the matter:

  1. Accretion disk formation: As matter gets closer to a black hole, it forms an accretion disk around it. This is a rotating disk of gas, dust, and other materials that are heated and accelerated due to the black hole's gravity. The accretion disk emits radiation, which can be observed as X-rays, visible light, and other forms of electromagnetic radiation.

  2. Spaghettification: As the matter moves closer to the event horizon, it experiences extreme tidal forces. These forces stretch and compress the matter, causing it to elongate and become "spaghettified." This process is also known as the "tidal stretching" or "tidal distortion" of the infalling matter.

  3. Crossing the event horizon: Once the matter crosses the event horizon, it is irretrievably lost to the outside universe. From an external observer's perspective, the matter appears to slow down and eventually freeze at the event horizon due to the time dilation effect of the black hole's gravity. However, from the perspective of the infalling matter, it continues to fall inward.

  4. Singularity: The ultimate fate of matter inside a black hole is not yet fully understood, as our current understanding of physics breaks down at the singularity. The singularity is a point of infinite density and curvature in spacetime where the laws of physics, including both general relativity and quantum mechanics, are not applicable. It is hypothesized that the matter is crushed into this singularity, but the exact nature of this process remains a mystery.

In summary, matter that falls into a black hole gets stretched and distorted due to tidal forces, crosses the event horizon, and ultimately is thought to be crushed into the singularity at the center of the black hole. However, a complete understanding of this process awaits a unified theory of quantum gravity that can describe the behavior of matter and spacetime under such extreme conditions.
