Voyage of the Stars

Scientists said that the reason was that time and space changed, but it was just one sentence, and no specific explanation was given, but their research on this did not stop.

In the following time, scientists threw various experimental bodies into the black hole, such as strong materials, various antimatter rays, etc., and then observed them through the detectors launched before.

In this way, the experiment was carried out again and again, and human civilization gradually found some useful things from the massive data.

For example, the theory of time and space specificity was brought out again.

Some scientists said that the reason for the centrifugal force reversal phenomenon in the photon sphere is that the time coordinates and space coordinates in the black hole are interchanged, that is, the Schwarzschild radius R becomes the time axis, and the original time coordinate T becomes the space coordinate.

This statement seems to be the case. It explains that after the matter passes through the one-way membrane, it will fall rapidly to the singularity, that is, the position where R is equal to 0. It is the result that the space coordinates in the one-way membrane have been interchanged with the time coordinates.

But it just seems that the "inside the black hole" in this theory originally refers to the area from the event horizon to the singularity. This area is the area where the time and space coordinates are replaced, not the photon sphere.

In response to other people's doubts, the scientist who put forward this view explained that the final outcome of matter after entering the innermost stable circular orbit of a black hole is to fall into a black hole, and the photons on the surface of the photon ball cannot come out either, and will eventually be swallowed by the black hole in one direction. The photon ball that people see is just the scattered photons on the critical surface of the photon ball.

Nowadays, there is a theory in the theory of black holes in human civilization, saying that the singularity of an ordinary black hole is only infinitely close to it but not a real singularity, and the space outside the singularity is not everything from the perspective of space-time dimension. At the same time, in the event horizon of a black hole, at the position where R is equal to 0, the space coordinates in the one-way membrane have been exchanged with the time coordinates.

So it is obvious that the time direction in the event horizon of a black hole points to the position where R is equal to 0.

The mass matter in the innermost stable circular orbit and the zero-mass photons in the photon ball conform to the one-way membrane description of this theory, so the scientists who insist on this view feel that their views are correct.

Another group of scientists do not support this rigid view, but they believe that the human substitution of time coordinates and space coordinates within the black hole event horizon is correct, but they also understand that this theoretical inference cannot be found in experiments with current human technology.

Because that requires understanding the nature of space and time, at least having a deep understanding of these two physical quantities, and obtaining information about the time attributes that have been pulled out by the black hole and converted into space attributes, or vice versa, in order to verify whether this theory is correct.

Obviously, this is a dead end for the current level of human technology.

For this reason, most scientists sneer at the idea of ​​explaining the counterintuitive characteristics of the photon ball from this direction, and they believe that the photon centrifugal force does not exist at all.

It's very simple. The centrifugal force theory is for the mass reference system. Photons have no mass at all, so there is no centrifugal force reversal.

This statement directly points to the core argument of previous scientists' research on the photon ball, forcing those scientists who have been studying this for many years to face the problem.

In particular, the problem of stable operation of photons in the photon ball cannot be explained by centrifugal force. It can also explain the phenomenon that tachyons cannot escape. After all, tachyons have negative mass, so it is logical to be subject to negative centrifugal force.

But for zero-mass photons

After some calculations and inferences, scientists believe that it is caused by the strong gravity of the black hole, or that the strong gravity distorts space-time.

To explain this, there are two different views among them. One school believes that the black hole swallows matter only in and not out, which means swallowing space-time itself, and the other school believes that it only swallows matter that exists in space-time.

The difference between the two is easy to distinguish. If space is regarded as water, then the former black hole is an existence that exists in water and swallows water infinitely.

The latter black hole is a black hole that exists in water and only curls the water into a hole that leads to the infinite abyss downward. The water around this hole is all stationary, but because of the curling, there is a potential energy that falls downward around it, so everything falls into it, which is gravity.

Human scientists are not all black and white. Some of them have put forward their own views based on these two schools of thought. They believe that both have their merits and are biased. If space is regarded as water, then the swallowing of a black hole should be to carry the water flow to do rapid twisting and rotating motion, and to make all the surrounding matter have the potential to fall inward.

Of course, this is just an inappropriate metaphor. The situation of a black hole is of course much more complicated than a vortex in water.

However, these scientists believe that their views are correct, because it can explain why photons in the photon sphere form a stable photon sphere, and why the photons in the photon sphere in general relativity show the phenomenon of "negative centrifugal force" but can still be stable in this area.

The reason they gave is also simple, that is, the speed of space rotation is too large due to the strong gravity within the range of the black hole photon sphere. Of course, space and time are one, so the so-called space rotation speed is actually the distortion of space and time.

That is, the degree of space and time distortion is greater than the speed of light!

Everyone knows that in the depths of the distant universe, the speed of space-time expansion is greater than the speed of light, so there is the saying of "chasing the first ray of light in the universe", and now this view tells humans that the space-time distortion here in the black hole or the rotation speed of space itself is also greater than the speed of light.

This leads to the fact that the speed of light inside it can never catch up with the space in front, and finally the space itself goes around the black hole and catches up with the light again. This is why humans use photons as a research perspective to obtain anti-logical calculation results.

And tachyons are faster than light, and because of the negative centrifugal force of negative mass, they fall directly into the black hole, which is consistent with the calculation.

This argument can also be extended and used to explain the black hole theory, when describing the illusion that objects will be "stuck" on the black hole event horizon and never fall into the black hole.

In short, in subsequent research, this view has gradually been recognized by more and more scientists, so that it has almost become the new knowledge of the entire human cognition of black holes. Before other theories come out to overturn it, it is basically considered to be correct.

Because it can explain cosmic phenomena!
