Something wrong with the galaxy?

What is the edge of the Milky Way, the home of human existence, and the home of the Milky Way? Far from us, the edge of the Milky Way is a very special place, surrounded by a giant halo of hot plasma and dotted with globular clusters, ancient stars, and perhaps even remnants of a ghost galaxy that predates the Milky Way.

As we explore more deeply, the mystery of the Milky Way grows, and recently, an astrophysicist presented research suggesting that a mysterious, unknown force is tearing holes in the galaxy. What exactly is going on?

Scientists have further investigated the cause of these disruptions, which are known as cosmic bullet holes, or things that look like they are being knocked around causing holes in the galaxy, so how do scientists identify the holes in the galaxy? According to research by Anna Banana at the Harvard Smithsonian Center for Astrophysics, a surprising anomaly was found in a uniform stellar stream in the outer halo of the Milky Way, which has a strange kink caused by a closure that looks like a cosmic fist going through the tide and dragging stars.

The alignment of stars in a galaxy is called a stellar stream, and this stellar line passes through the galaxy as a group with a single gap where the gravitational pull of the galaxy should draw a straight line across the sky, however, there is a huge hole in the stellar stream that appears to have been made by a powerful force that has jagged the stars out of order due to the force of the impact. The galaxy in which this hole is located is gd1, a globular cluster, and the remnant of a group of old stars with 70,000 times the mass of the Sun. gd1 was destroyed in the past due to gravitational interaction with the Milky Way. Fortunately, however, this mysterious force is very far from the solar system, so the solar system is safe for the time being.

According to Banana's examination, the new hole appears to have been pierced by something. First, they were able to determine that the imp actor is more massive than any star in the Milky Way and that its mass is millions of times greater than that of the Sun, and scientists suspect that the imp actor is not comparable to known galactic black holes and that it is unlikely to be stellar. Experts have also concluded, based on comparisons, that the jagged black hole in Gd lacks the other characteristic flares or radiation exhibited by black holes. If it were a black hole, it would be a supermassive black hole, but if it were a black hole, it would reveal features that are not at all consistent with a black hole

After ruling out stars and black holes, scientists believe the likely force piercing the galaxy is dark matter, an invisible component that keeps galaxies together and accounts for about 25 percent of the matter and energy of the universe. Gravity holds the universe together. We know how it works, but we are not sure of its actual nature. The mass in the form of stars, dust, and gas must be about 27% higher than what we can perceive because it is undetectable. It is called dark matter, but we have not been able to determine its composition. It is one of the most mysterious things that has ever existed.

However, this unusual observation has left scientists wondering about the existence of dark matter, even though the theory is far from proven. But the dark matter may be the best explanation. Dark matter does not reflect any light, it is almost invisible and only produces gravitational forces, in this case, it may have a cosmic influence. The matter piercing the galaxy, for example, is composed of this mysterious substance, but how are scientists going to prove that it is dark matter? After all, this is a subversive theory!

According to current theories about how the universe was formed, scaffolds around which astrophysical objects made of ordinary matter such as galaxies are assembled may have thousands of small dark matter clumps clustered in and around galaxies, often called dark matter subhalos, which are completely dark and devoid of any stars. Although they cannot be measured directly, scientists can provide indirect evidence of the presence of dark matter by observing gas or dust from the motion of stars in galaxies, so researchers must create new ways to study sub-halos that do not contain any regular matter, for example, if dark matter can be present in galaxies.

If researchers can reach this conclusion, it would be a discovery that would change the current rules of physics, because the mass of the tiniest dark matter clumps is closely related to the mass of as-yet-unidentified dark matter clumps, and dark matter is made up of particles, more specifically, the mass of the particles increases with the size of the dark matter clumps, so is it dark matter that pierces the galaxy? It would be very surprising if scientists found out that it is, because it may provide us with more information about dark matter, but of course, it is only a speculation of dark matter, and more direct evidence is still needed whether dark matter exists.
