Review
Laniakea Supercluster, it is one of the breathtaking wonders of the universe. Its magnificence lies not only in its sheer size and number of galaxies, but also in the mystery and unknowns hidden behind its depth.
The Laniakea Supercluster is not only a collection of galaxies, it contains many unknown dangers, shocking secrets, and may even involve the fate of the universe.
Huge family
The Milky Way, as we all know, is like a busy city with countless shining lights, and this is where we live and explore.
However, don't think that the Milky Way is a lonely family, it also has many neighbors who have come together to form a large family called the Local Group of Galaxies. There are about 50 galaxies in this large family, the most famous of which are the Milky Way and the Andromeda Galaxy. The diameter of this group of galaxies is about 10 million light-years, which is 100 times the size of the Milky Way!
You may think that the local group of galaxies is big enough, but in reality, it is only a small part of a much larger structure. There are 100,000 galaxies in this structure, which is named the Laniakea Supercluster, or simply the "La Cluster" for convenience.
This superfamily is one of the largest in the universe as we know it, its size and weight are much larger than you might think, and its movement and development are full of unknowns and surprises.
The name is actually a Hawaiian word meaning "endless paradise." The name was not chosen casually, but in homage to the Polynesians who sailed the Pacific Ocean with their astronomical knowledge.
It is also a fitting illustration of the magnificence and diversity of this supercluster. Imagine that this superfamily is 520 million light-years in diameter, which is more than 1,000 times the distance from Earth to the Andromeda Galaxy. It weighs about 10 times the power of the Sun and 17 times, or 100,000 times that of the Milky Way!
The family is a trinity of three main components: the Virgo Supercluster, the Serpent-Centauri Supercluster, and the Peacock-Indian Supercluster.
The Virgo Supercluster is a superfamily of galaxies in the Milky Way, home to about 2,500 galaxies. The largest of these is the Virgo Cluster, which has about 2,000 galaxies and is our closest large neighbor.
Then there's the Serpent-Centauri Supercluster, which is the gravitational center of the family, attracting galaxies to it.
The Peacock-Indian Supercluster, on the other hand, is another important part of the La cluster, located in the southern sky and home to about 1,000 galaxies. The most conspicuous of these is the Peacock Cluster, which consists of about 300 galaxies and is one of the most dazzling groups of galaxies in the southern sky.
Not only do the Pull Clusters have these three main members, but there are also nearly 300 smaller clusters and groups of galaxies. They are scattered in different directions and distances, forming an intricate network.
However, the actual number may be higher because the Milky Way's hidden zone obscures part of the observed area. Perhaps, there are some undiscovered clusters and groups of galaxies lurking in some places that have not been observed by humans.
Superclusters, as imposing as they sound, are the giants of the universe that are formed by gravity that brings clusters and groups of galaxies together.
But these superstructures are not as static as water, they are constantly affected by the gravitational pull of other superclusters around them, and they have to deal with the expansion of the universe.
As a result, they are likely to undergo dramatic shifts over the next few billion years. Like the Ra Star Cluster, it is moving towards a mysterious realm where there is a center of gravity.
Laniakea may be just one corner of a much larger system, such as the Sharpley Supercluster, one of the largest structures in the known universe. So, even a superfamily may only be part of a much more complex superstructure. The changes and developments in the future make all this full of mystery and uncertainty.
How terrifying it is
First of all, the Ra star cluster is not static, it is moving at a speed of 600 kilometers per second towards a mysterious location, which is known as the "giant gravitational source".
This location has a mass equivalent to tens of thousands of galaxies, and all galaxies are irresistibly attracted. The true identity of the giant source remains a mystery to this day, and it may be a massive black hole, a larger supercluster, or an unknown cosmic phenomenon.
Either way, its attraction to the Pull Cluster is unusually strong, affecting galaxies hundreds of millions of light-years away, including our dear Milky Way. This means that our homeland is being led to an unknown fate by the Pull Star Cluster, and there is nothing humanity can do about it.
Second, the inner galaxies are not at peace with each other, and they often collide and merge, producing enormous amounts of energy and radiation that can have devastating effects on the surrounding stars and planets.
For example, the Milky Way and the Andromeda Galaxy are about to collide, and in 3.75 billion years, they will form a new galaxy called the "Galactic Andromeda System".
In the process, hundreds of millions of stars could be thrown or destroyed, and the fate of the solar system is difficult to predict. And such collisions are not uncommon, and the chaos and destruction caused can be described as unimaginable. All of this makes the Pull Cluster even more mysterious and terrifying.
There are also many unknown dangers hidden within the cluster, such as super-black holes, matter unknown to humans, and other forms of energy. These phenomena belong to the mysteries of the universe that we have not yet fully understood, and they may have an important impact on the movement and evolution of the universe, and even pose a fatal threat to the existence of human beings.
For example, each galaxy in the Pull Cluster may harbor a supermassive black hole with a mass of hundreds of millions of times the mass of the Sun, which can devour stars and planets, releasing extremely destructive rays that can have a significant impact on the surrounding galaxy system.
Both dark matter and dark energy are currently completely unknown to human beings, but they may be the cause of the expansion and acceleration of the universe, and they may also be the key to the formation and movement of superclusters.
epilogue
The horror of the cluster depends on the angle from which you look at it. For a tiny being like us, it unfolds an amazing cosmic wonder, highlighting the magnificence and diversity of the universe.
But for itself, it is a dynamic system that is constantly changing, subject to multiple forces and potentially changing dramatically over the next few billion years. Perhaps it is not a safe and stable "paradise", but more like a "hell" full of challenges and adventures. This diversity and mystery is the mystery of the universe.
