How Large-Scale Structure Formation in the Universe Happens

The large-scale structure of matter is enormous but predictable in many aspects. 

Physicists have calculated about the number of times the proton and electron in an atom can be split, the fraction of protons to electrons and the fraction of protons and electrons in a nucleus. They also have calculated the rate at which these collisions occur. All this tells us about the structure of matter.

The fraction of protons to electrons is known as the half-life of a particle, because the time it takes for an electron to become a quark depends on the energy of its interaction with a quark. 

The value of this specific function is called the density of the proton, which directly indicates the amount of matter at a given temperature. The large-scale structure of matter relies on such predictions, because the rate of collisions that these calculators are able to measure is very sensitive to the model of the universe in which they are working. The large-scale structure of matter is not a one-size-fits-all kind of thing, since the constants of nature, the density of matter and the total number of protons in atoms are not the same everywhere. So a model of the universe that incorporates all of these parameters must be able to run efficiently in various situations.

Experiment #1 – each point in space has a distinct gravitational field that brings it into formation. 

This is the so-called cosmic strings theory. In 2021 a group of researchers made an experimental verification of this cosmological law using a powerful laser at Cagle National Park in Arizona. They found that the distribution of distant quarks in space depends on the makeup of this cosmic string. Based on this research, the researchers came up with a model of the universe that includes large-scale structure of matter.

Experiment #2 – creating computer simulations of the early universe. 

Although the simulations showed some level of accuracy, the accuracy was considered minimal when dealing with large-scale structure of matter. In order to remedy this problem, scientists simulated the formation of clusters of galaxies using high-quality software. By applying steady pressure on groups of these cluster’s members, scientists can observe the effects on the various properties of these cluster’s matter. They discovered that the expansion of the universe occurred at a slower rate than expected, and the clusters formed much later in time than was previously thought.

Experiment #3 – simulation of the creation of the first galaxies in space. 

By assuming that the initial density of dark matter was less than the present-day value, they were able to calculate the number of galaxy clusters with a mass between about one and two times the density of our own Milky Way galaxy. Surprisingly, they found that about half of these clusters have a completely identical composition to our own. These simulations have provided astronomers with a better understanding of how galaxy formation works in our very unique cosmic environment. This study’s results were published in a recent issue of a scientific journal.

The distribution of dark matter in space is studies through the filaments of energy. 

A filament is a collection of quarks held together by their strong force. Astronomers have found many strong filamentary structures, including large-scale structure of matter within clusters and the major galaxy groups. Although not all of these structures are made of quarks, the presence of these filaments indicates that our very own Milky Way must contain a super dark matter, which scientists believe is necessary to produce the large-scale structure of matter within the universe. The simulations that have been conducted with this model indicate that the primordial super grain may be present.

Another group of studies looked at the effects of shockwaves on heavy elliptical galaxies. 

They simulated a minor shockwave passing through a galaxy to see what effect it would have on the formation of stars within it. They found that the amount of radiation coming from the nucleus was greatly reduced during the passage of this shockwave. In this way, they were able to pin-point the reason why this occurs. It is thought that a cloud of dust forms around the nucleus, which absorbs most of the radiation coming from the stars and creates the gaps between the clouds.

Astronomers have used these same simulations in order to learn more about the process of galaxy formation and the early universe. This is because they can test their predictions and see if they fit with observations made. The simulations have enabled them to test different assumptions about gravity and density of matter, as well as detect the existence of “icyclic” gravity, which occurs at very high speeds.
