Black holes are so dark, how to study them

A black hole is a substance without substance, and we are not studying its color, but its cosmic significance.

To explore black holes, you need to use a telescope, and some molecules are invisible to the naked eye

Black holes are still quite dangerous, and since we want to study them, we must be prepared for all possible dangers and improve our science and technology.

By calculating the surrounding data, including diameter, gravity, etc., the characteristics of black holes can be understood, which is convenient for human research.

The gravitational pull of a black hole can't even escape light, so it means that it can be used to tunnel space-time. Because the generalized sense is relatively mentioned, any object can travel through time as long as it reaches the speed of light! Black holes may cause large ** (Tunguska big ** has the black hole hypothesis).

What exactly is inside a black hole?

Now, what enters the black hole is stellar dust, gas, light, spaceships with robotic astronauts, and garbage to be converted into energy. Either way, the trapped matter only increases the mass of the black hole itself, while also expanding its radius and surface. If the mass is doubled, the radius is also doubled, and the area of the horizon is increased by a factor of four.

Since it is continuous, the increase is gradual. However, there is a special case, that is, two black holes may touch and collide with each other, and in the process of attracting each other, one black hole enters the other, and the two black holes become a single black hole, while all the components of the two black holes are retained. A larger single black hole may collide with another black hole, and so on, resulting in a more massive and larger black hole.

It is believed that during the collision, about one thousandth of the black hole's static energy is released, which is emitted into the universe in the form of gravitational waves, and the speed is the same as light, its area continues to expand, and the entropy of the black hole also increases. That is, the internal "confusion" is growing, that is, information about the inhaled substance is unusable and cannot be remedied, as if a computer accidentally messed up the letters of a freshly written article. Therefore, only three pieces of information can be transmitted from a black hole that describe it:

Mass, angular momentum (referring to the rotation of a black hole), and electric charge. Wheeler likens this information to a bald man with only three hairs on his head, and it is impossible for us to know what substance is falling into it. On the basis of these three types of information, black holes can be divided:

A Schwarzschild black hole with no angular momentum and no charge, which has the properties of a "singularity" and a "horizon"; Kerr black holes with angular momentum but no charge; and black holes that have angular momentum and are charged. In addition, it is possible to distinguish from the origin of black holes. But the latest classification relies on "color".

This seems a bit ridiculous, how can a black hole that does not emit a beam of light inside be colored? Actually, the colors mentioned here are not the usual colors of red, blue, green, etc., but are used to distinguish the different state "colors" of quarks. Quarks are smaller elementary particles that make up protons and neutrons.

For our astrophysicists, the chase to collect the different "colors" of black holes in the process of tracking infinitesimal to infinitesimal and from infinitesimal to infinitesimal begins in the process of tracking infinitesimal to infinitesimal and from infinitesimal to infinitesimal small.

The numbers in the figure represent the smallest unit of indivisible positive and negative chord information - string bits

Famous physicist John. John Wheeler famously said, "It from bit."

After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits) Note: Bits are bits.

Albert Einstein, who used the limit of equations to prove the existence of black holes.

2.Stephen Hawking, who dedicated his life to the study of black holes, popularized them and brought them into a whole new field.

3.Cal. Schwarzschild mathematically proved the existence of black holes and the surrounding matter.

4.Roger. Penrose, from the noisy silver mathematical liquid feast, further proves the avoidability of the existence of singularities (black holes).

1. Your theory is wrong in the first place. "According to the theory of relativity, when a star collapses to the point where it is about to become a black hole, its gravitational bell effect is so great that it takes much longer to collapse into a black hole than the lifetime of the universe. ”

This is observed as an observer outside the event horizon (and requires that the other party is a static, non-luminous Schwarzschild black hole), and if the observer is located on the surface of the star collapsing along with the star, it will be observed that the surface of the star falls into the event horizon and is compressed into a black hole. Therefore, black holes are formable and do not "take much longer to collapse into black holes than the lifetime of the universe". Moreover, many stars that are very likely to be black holes have been discovered, such as the famous constellation Cygnus.

Black holes are extreme astral bodies that are the domain where the theory of relativity and quantum science comes into play. The data and evidence provided by the study of black holes are important for advancing the theory of relativity as well as quantum theory. Adopt it.
