Could the ninth planet be a primary black hole? It’s the size of an atom, but it weighs a billion tons

At the 26th International Astronomical Union in 2006, Pluto was demoted and kicked out of the nine planets.

Because Pluto’s volume and mass are relatively small, compared with the moon, its mass is only one sixth of that of the moon, and its volume is only one third of that of the moon. Its gravity is not enough to clean up other celestial bodies in its orbit, so it is degraded to a dwarf planet.

So there are only eight planets left in the solar system, which are Mercury, Venus, earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Because Pluto’s downgrading has resulted in the vacancy of the ninth planet in the solar system, scientists have been searching for another ninth planet in recent years.

It is reported that yakubo Schultz of Durham University in the UK and James Wen of University of Illinois at Chicago in the US have been interested in watching a documentary about the ninth largest planet in the planetarium, and they want to find out whether other objects can “imitate” planets, such as boson stars, dark matter halos and proto black holes And other possibilities. Therefore, it is proposed that

The ninth planet may not be a planet, but a primary black hole.

Before we know what a primary black hole is, we need to know about it.

How do black holes form?

When a star with enough mass is aging (its mass is at least 3.2 times larger than that of the sun), its thermonuclear reaction will consume the fuel in the center, and it does not have enough strength to bear the huge weight of the shell, so it can not bear the gravity of the shell, and the core will start to collapse until it finally forms a star with nearly infinite volume and almost infinite density.

When its radius shrinks to less than the Schwarzschild radius, the distortion of space-time caused by mass makes it impossible for even light to shoot out, and the black hole is formed.

The nature of black hole

The gravity of a black hole is very strong. All kinds of materials, including light, cannot escape being swallowed by black holes. Also because of the huge gravity of the black hole, it can’t emit and reflect light, so it can’t be directly observed outside, only through the relative motion of the surrounding objects, to make indirect observation.

Primary black hole

The primary black hole is a hypothesis put forward by scientists. It is not formed by the collapse of stars, but in the big bang, because of its extraordinary force, it squeezed some matter very tightly.

Moreover, primary black holes are much smaller than ordinary black holes, and may even be too small to be recognized by naked eyes. For example, a primary black hole may be the size of an atom, but its mass is equivalent to a mountain larger than 1 billion tons.

A team at the University of Tokyo reanalyzed the data collected from the optical gravity lens experiment (ogle) a few months after it began exploring hypotheses about the nature of the ninth largest planet

The mass of a primary black hole is basically the same as the predicted mass of the ninth largest planet, so it is possible that the ninth largest planet may actually be a primary black hole.

conclusion

Xiao Bian thinks that although all kinds of conjectures about the ninth largest planet are just conjectures at present, if we want to find the proof that the ninth largest planet is a primary black hole, we have to wait for scientists to carry out more in-depth exploration, and perhaps with the development of science and technology in the future, we will have a conclusion.

For the ninth planet, do you think it will be a primary black hole? Welcome to comment area.
