Chapter 1: The Mystery of Tabby’s Star

In the vast expanse of the universe lies a peculiar star that raises intriguing questions about the existence of advanced civilizations. Located 1,500 light-years away, Tabby’s Star, or Boyajian’s Star, exhibits irregular brightness fluctuations that defy simple explanations. Initially thought to be a minor curiosity, these anomalies may hint at the presence of a sophisticated alien megastructure.

Section 1.1: Searching for Advanced Civilizations

One method of detecting advanced civilizations involves observing their technological signatures. While their technologies might be beyond our current understanding, they would still adhere to the same physical laws we recognize. Thus, astronomers look for radio frequencies that we would likely use, considering that other civilizations might do the same.

In a previous article titled “Did Aliens Contact Us In 1977?”, we noted a peculiar signal resembling intentional communication on the hydrogen line frequency, which we would utilize to reach out to extraterrestrial life. But what if there exists a civilization far more advanced than our own?

Subsection 1.1.1: The Kardashev Scale

The Kardashev Scale is a framework that categorizes civilizations based on their energy consumption. A Type I Civilization harnesses the resources of its home planet, a Type II Civilization utilizes the energy of its star system, and a Type III Civilization can control energy on a galactic scale.

Currently, we can reasonably assume that Type III civilizations do not exist within our Milky Way unless they view Earth as a kind of zoo. However, there may be a Type II civilization operating near the enigmatic Tabby’s Star, given its potential to construct a structure beyond our imagination.

This hypothetical structure, known as a Dyson Sphere or Dyson Swarm, could capture most or all of the energy emitted by its star, channeling it for the civilization's use. This would grant them immense power while preserving the integrity of their home planets.

To illustrate the scale of this energy, if we could harness the Sun's energy for just one second, it could provide enough power for the United States for 60 billion years. Such advancements would allow civilizations to address challenges in ways that are currently unimaginable.

Section 1.2: Constructing a Dyson Sphere

But how would one capture such immense energy? There are two proposed methods. The first is the Dyson Sphere, a massive hollow structure that envelops a star and its major planets, with solar panels lining its interior to provide energy to the orbiting planets. This monumental object poses significant engineering challenges, leading some scientists to propose a more feasible alternative: the Dyson Swarm.

A Dyson Swarm consists of numerous energy-harvesting satellites that orbit the star, capturing energy at a distance comparable to that of a Dyson Sphere. While it may not collect all available energy, it is theoretically possible to construct such a system using contemporary technology.

The first video titled "Did Scientists Discover Alien Mega-Structures?" explores the intriguing possibilities surrounding these potential structures.

Artists have created stunning visuals, such as one depicting a Dyson Swarm mining Mercury for resources, thus preserving Earth's materials while tapping into vast stellar energy reserves.

Chapter 2: Investigating Tabby’s Star

So, how can we identify these extraordinary star systems? They are likely to be mature stars, akin to our Sun, that have had the time—several billion years—to support the evolution of intelligent life. The light from such stars could be regularly obscured by satellites in a Dyson Swarm or completely blocked by a Dyson Sphere.

In 2015, astronomers observed that Tabby’s Star exhibited dimming patterns that could not be explained by standard solar activity. Initial hypotheses suggested that planets were crossing in front of the star, but these did not align with expected patterns, leading some to propose the Dyson Swarm theory.

However, another plausible explanation is that the star's dimming results from irregularly orbiting dust and comets. Given the star's maturity, it is unlikely to have a cloud-like debris field; such material should have coalesced into planets long ago.

In 2019, astronomers proposed that icy moons from the star's planets might have been stripped away, forming a lopsided ring of debris similar to Saturn's rings but with a distinctly uneven appearance, which could account for the unusual dimming.

Nevertheless, the search for evidence of a Dyson Swarm continues. If such structures exist, they must be channeling energy back to a planet for its civilization to utilize. Detecting significant energy transfer could lend credence to the Dyson Swarm hypothesis.

Astrophysicists have focused on searching for laser signals, as these would represent the most efficient method of energy transport within a Dyson Swarm. Unfortunately, no such signals have been detected, which lends support to the theory that the dimming is due to disrupted icy moons.

The second video titled "New study finds potential alien mega-structures known as 'dyson spheres'" delves into the latest findings surrounding this captivating topic.

For now, it appears that Tabby’s Star does not harbor an advanced alien civilization. However, the failure to detect this star's dimming until 2015 was due to our algorithms not being programmed to identify such phenomena.

Since then, these algorithms have been refined, leading to the discovery of numerous stars exhibiting similar dimming behaviors that had previously gone unnoticed. As research continues, we are now better equipped to analyze these stars for signs of energy distribution, a crucial indicator of Dyson Swarms.

While it may be disappointing that Tabby’s Star likely does not represent an alien megastructure, it has opened the door for us to uncover other stars that may harbor such technologies that were previously undetectable. The realization that we were unaware of such stars before 2015 is astounding, and now we possess the tools to explore and investigate potential cosmic neighbors. The lessons learned from Tabby’s Star could prove invaluable in our quest to identify Type II civilizations.
