It works the same way, but the time on the moon is different. Because the celestial body has no atmosphere, nothing moves on its surface, so it bears traces of the history of the solar system, but if we look closely, we can even find traces of the birth of the universe.

According to the theory of Bernard Carr and Stephen Hawking in the 1970s, after the Big Bang, the universe was filled with energy and a lot of matter in small places, and due to fluctuations in density, the primordial collapsed into black holes of all sizes. Supermassive black holes formed at one end of the spectrum and black holes were slightly larger than atoms at the other end. According to Hawking and Carr

The first black holes still exist in the universe.

During the Big Bang, these first black holes formed in quantities that, according to some scientific views, contained the dark matter that makes up the vast majority of the universe. The only problem is that no one knows for sure if these ancient black holes ever existed.

If they existed, say at an atomic size, and once a swarm of black holes passed through the solar system, they would almost certainly collide with a few planets. If this happened to Earth, its traces are now gone due to movement of geological plates, water and wind erosion. It would be different if one found the moon – we will still find traces of it today.

The dark side

The root of the idea is that the stars that make up the arms of galaxies rotate around the center at a very high speed. However, galaxies do not fall apart, so it is assumed that they are bound together by a gravitational pull of unknown origin, and the cause of the gravitational pull is dark matter. Physics has not yet been able to clearly detect dark matter. According to one theory, dark matter consists of so-called WIMP particles, which, like neutrinos, for example, hardly interact with other matter but have a mass more than a thousand times that of a proton.

In parallel, there is the theory of the occasional and then recurring disappearance of ancient black holes. The idea last came back in 2016, when LIGO’s international gravitational-wave detector first detected a black hole collision.

Star-sized black holes form when a larger star runs out of fuel and collapses. The outer part of the star is taken down by a huge, bright explosion called a supernova. The star’s core then collapses to a maximum density because it is unable to withstand gravity. In the middle of a black hole, gravity is so strong that nothing can cross the boundary called the event horizon, not even light.

Prior to LIGO’s measurements, astronomy knew that black holes compress the mass of the Sun by about twenty times. In the first LIGO measurement, the colliding black holes were the largest to date, weighing thirty days. Subsequent measurements showed similar masses, but there was also a black hole 100 times larger than the Sun. According to the theory, the last giants include ancient black holes and those smaller than the mass of the Sun.

We know that the smallest black holes have now evaporated. It may still be slightly present and identifiable by X-ray. Hawking described that black holes radiate energy and run out after a very long time and then disappear in a flash. Ancient black holes, which have a mass slightly more but barely a bit larger than an atom, have a lifespan longer than the current age of the universe, but are difficult to detect.

Matthew E. Kaplan and Almog Yalin, who compare the difference between an asteroid and a black hole colliding with a celestial body in models. The result was completely different: the former had a mass similar to the mass of the Moon and, upon impact, would release all its energy, and the latter, much thicker than the Moon, would pass through it almost unhindered.

They travel at an incredible speed, two hundred kilometers per second. They were going through it like a bullet on cotton candy

Kaplan noted.

The key is that after the standard impact, the ejected material will return to a flat ring, while in the case of a black hole, much steeper rings will appear and, according to models, will be at least one meter in diameter. NASA’s Lunar Orbiter Reconnaissance Orbiter, which is currently orbiting the Moon, is capable of taking images with this resolution and can use a machine learning algorithm to find black hole collisions, but even if the right impact trace is found, in situ exploration should justify it. Harsh conditions exist molten silicates and quartz.

According to Kaplan and Yallenwich, the chances of a lunar black hole occurring are ten percent. The tracking will last for a billion years before subsequent meteorite strikes wipe it out. However, professional criticism has questioned this, arguing that it would only take about 15 million years for the traces to disappear. Yalin agreed with the latter, but he believed that if we carefully looked into everything on other planets in the solar system, Mercury, Mars, Pluto, or any other rocky moon, we could still find traces of the influence of an ancient black hole.
