Heaven

The cosmos, vast and enigmatic, has captivated us since time immemorial with its mysteries and wonders. In the midst of this vast stellar space, a term that scientists coined in 2014 emerges: Laniakea. It is not a star, a planet or a galaxy; It's much more than that. Laniakea is the immense superstructure that houses our galaxy, the Milky Way, and many other galaxies.

In this article, we'll dive into the concept of Laniakea, exploring its meaning, discovery, and the amazing connection we share to this vast cosmic web: exploring Laniakea, our cosmic home in the universe.

The etymological meaning of Laniakea

The word "Laniakea" comes from Hawaiian and means "vast sky" or "vast and welcoming sky." It was coined in 2014 by a team of astronomers led by Brent Tully of the University of Hawaii. This name embodies the essence of its discovery: an immense cosmic conglomeration that brings together countless galaxies, including our own.

The discovery of the Laniakea superstructure

The universe has a structure in the form of a cosmic network

The discovery of Laniakea is not only a scientific feat, but also a testament to the power of international collaboration and astronomical observation. Astronomers realized that galaxies are not randomly distributed in the universe, but instead form structures through interconnected filaments. By observing the velocities and positions of thousands of galaxies, scientists have drawn a three-dimensional map of the regions of space that are bound by gravity. This research resonates with the mayan astronomy, who also sought to understand the cosmos.

The Milky Way in the cosmic context

One of the most fascinating aspects of Laniakea is that our galaxy, the Milky Way, is only a part of this vast cosmic web. We are gravitationally connected to other galaxies in our Laniakea region, which invisibly and intrinsically links us to the entire universe. This connection highlights how we are an intricate part of a cosmic fabric much larger than we could have imagined.

The dance of the galaxies: understanding the organization of this superstructure

the movement of galaxies in the universe is mainly due to the gravity exerted by dark matter

Imagine Laniakea as an immense fabric in which galaxies are interconnected and dance to the rhythm of gravity.. The closest galaxies are strongly influenced by the gravity of the others, giving rise to a cosmic choreography that transcends space and time. This dance of galaxies is a tangible manifestation of the fundamental laws that govern the universe. and reflects the large-scale structure that has evolved over billions of years. This phenomenon can also be compared to the way in which buddhism rites in relation to his spiritual cosmos.

It is a superstructure that would materialize Einstein's theory of relativity and Newton's theory of universal gravitation, where it is explained that space-time forms a fabric that is deformed by the action of gravity. The result would be an ordering of cosmic space that has been called "Laniakea".

Laniakea structure in superclusters

Laniakea is organized in a hierarchy of galactic groupings, with superclusters being one of the largest and most significant structures within this organization. Superclusters are massive clusters of galaxies and groups of galaxies that are gravitationally bound.. These galactic groupings are distributed in a three-dimensional configuration that forms a kind of cosmic network.

The Laniakea Supercluster:

Scientists estimate that the Milky Way and Andromeda will collide in the future

Within Laniakea, one of the most prominent superclusters is the Laniakea Supercluster. This supercluster is a vast galaxy complex that spans hundreds of millions of light-years. It contains multiple smaller clusters and groups of galaxies that are gravitationally connected in a three-dimensional structure. The Laniakea Supercluster includes the Milky Way and the Andromeda galaxy, along with many other nearby galaxies.

How superclusters are organized:

Organization of Laniakea into filaments and nodes

The structure of the superclusters in Laniakea follows a pattern of grouping in filaments and nodes. Filaments are long, thin extensions of galaxies that stretch across vast distances in space, connecting nodes or points of higher density. These filaments can be hundreds of millions of light-years long and contain a large number of galaxies. The nodes, on the other hand, are regions of greater concentration of galaxies and dark matter. These areas are the centers of gravitational attraction that hold the surrounding galaxies together.

Formation and evolution of superclusters:

dark matter

The formation and evolution of superclusters are influenced by gravity and the distribution of matter in the universe. Dark matter, a form of invisible matter that does not emit light but exerts gravitational influence, plays a crucial role in structuring these large galactic groupingsAs dark matter clumps and concentrates in certain areas, it draws visible matter, such as galaxies, into those regions, leading to the formation of superclusters. This phenomenon mirrors the principles of Buddhism in the way the universe is perceived.

Laniakea Superclusters:

structural organization of laniakea

Within Laniakea's cosmic superstructure, there are four major superclusters: the Virgo Supercluster, the Hydra-Centaurus Supercluster, the Centaurus Supercluster, and the Southern Supercluster. We see them below:

  • Virgo Supercluster: The Virgo Supercluster is one of the closest superclusters to us and is an integral part of Laniakea. It contains the Virgo Galaxy and its galaxy cluster, which is one of the most massive and brightest clusters in the sky. The Virgo Supercluster has a significant gravitational influence on nearby galaxies and plays a fundamental role in the local dynamics of the group of galaxies to which the Milky Way belongs.
  • Hydra-Centaurus Supercluster: The Hydra-Centaurus Supercluster is one of the largest and most massive superclusters known. It includes the Centaurus Cluster, one of the closest and brightest galaxy clusters. This supercluster exerts a strong gravitational influence on nearby galaxies and is one of the reasons why the Milky Way and the Andromeda galaxy are on a collision course in the distant future.
  • Centaurus Supercluster: The Centaurus Supercluster, also known as the Centennial Supercluster, is a vast grouping of galaxies that is part of Laniakea. This supercluster is especially prominent in the southern hemisphere of the sky and stretches across hundreds of millions of light-years. It includes the Centaurus Cluster, one of the most massive galaxy clusters closest to Earth. The Centaurus Supercluster plays a crucial role in the structure and dynamics of the cosmic region it encompasses.
  • Southern Supercluster: The Southern Supercluster, also known as the Turkey-Indus Supercluster, is another major galactic grouping within Laniakea. As its name suggests, it is located in the direction of the southern hemisphere of the sky. This supercluster covers a large region and is composed of multiple clusters and groups of galaxies. The gravity exerted by the Southern Supercluster influences the trajectories and motions of the galaxies in its neighborhood.

These superclusters, along with other smaller clusters and galactic groupings, make up Laniakea's complex and hierarchical structure. Gravity is the engine that assembles these galaxies into ever larger clusters., giving rise to an interconnected cosmic web that defines our position in the universe on a large scale.

philosophical perspectives

Existentialism: philosophical current that considers the meaning of the existence of the human being

Laniakea has also sparked philosophical reflections on our position in the universe. While we are small compared to the scale of this cosmic superstructure, our existence has a deep meaning. We are conscious observers of this vast system, capable of both wonder and understanding. This sense of wonder and understanding connects us to the very forces and processes that shape the universe. From this perspective, we can compare our search for insights about Laniakea to the search for knowledge in diverse cultures, such as the egyptian religion.

However, the lack of understanding of much of the cosmos and the physical issues that transcend our capacity for observation and analysis highlight the limitations of our knowledge. many philosophical perspectives emphasize the importance of humility and open-mindedness in our search to understand the universe.

The human position in the universe can also raise questions about the meaning and purpose of our existence.. In considering the vastness of the cosmos and our insignificance within it, some philosophers have explored issues such as the search for meaning, the relationship between humanity and the cosmos, and the possibility that life forms and knowledge exist beyond our comprehension.

A search that continues

In the scientific field the work is indefinite. There is always more to discover and learn.That's why scientists continue to research tirelessly, because the universe is vast enough to make us realize that we only know "the tip of the iceberg," at best.

It is an immensity that transcends us and therefore Technological advances continue to be developed, in such a way that they can provide us with more details about Laniakea and other similar cosmic superstructures. Revelations that could deepen our understanding of the evolution of the universe and how galaxies interact over time.
