Why do scientists think that we live in a mild black hole?

In fact, under the premise of constant density, the natural radius of an object is directly proportional to one third of its mass, while the schwarzschild radius is directly proportional to its mass. So when the mass of an object exceeds the critical value, its schwarzschild radius will exceed the natural radius. After calculation, scientists have reached the critical mass of about 65.438+0.5 billion suns.

According to the above theoretical basis, scientists substituted the observed cosmic data into schwarzschild radius's formula. Through calculation, the schwarzschild radius of the universe is140-1500 million light-years, and we all know that the directly observed radius of the universe is1370 million light-years, which is basically consistent with the result calculated by schwarzschild radius formula. Therefore, some scientists have come to a bold conclusion: our universe is actually a super black hole.

This theory supports that for a small black hole, the curvature of spacetime in its horizon is extremely distorted, and when matter enters such a black hole, it will be torn. For a supermassive black hole, the density of matter inside it is not high and the distribution is relatively uniform (this structure is allowed under the framework of general relativity), so this black hole can be called a "mild black hole", and even matter can cross the horizon without destroying another universe.

The black hole universe model points out that the universe is a multi-level structure. There is a bigger universe outside our universe and a smaller universe inside our universe. The size of the whole space determines the total number of layers in the black hole universe. In the process of expansion, adjacent black hole universes may collide to form a higher universe.
