Chapter 1: The Enigma of the Universe

Humanity currently comprehends only about five percent of the cosmos. This limitation isn’t solely due to a lack of discoveries; rather, a staggering 95 percent of the universe is composed of dark matter and dark energy. These elusive components account for roughly 27 percent and 68 percent of the universe, respectively, and have puzzled scientists since their identification.

Dark matter was first theorized in the 1930s when astronomer Fritz Zwicky observed that galaxies were receding at speeds that should have caused them to fly apart. He proposed that an unseen force was binding them together. This idea gained traction when later observations revealed stars on the outskirts of galaxies were rotating at speeds comparable to those near their centers, suggesting the presence of an unseen mass now referred to as dark matter.

In contrast, dark energy is the more formidable of the two phenomena. Despite the immense gravitational forces exerted by massive stars and black holes, the universe continues to expand at an astonishing pace. The nature of dark energy remains a mystery; we are still uncertain about its composition or origin. What we do know is that it is the driving force behind the universe’s expansion, preventing the collapse of cosmic structures.

Recent inquiries by researchers have speculated whether dark energy could be instrumental in uncovering signs of extraterrestrial life. Given the vastness of the universe, the likelihood of randomly encountering alien life may be negligible for eons. However, dark energy might reveal their existence among the stars, even if a direct encounter is impossible.

Imagine Earth as a small vessel adrift on a boundless ocean with no propulsion. As we navigate, we observe logs and rocks, remnants of a past existence, floating by. While these objects may not be alive, their origins could offer insights into the surrounding environment. Unfortunately, as we drift further, some of these objects vanish beyond our horizon, lost forever.

In astronomical terms, galaxies represent the logs, dark energy symbolizes the ocean, and the horizon remains a boundary. There are regions in space beyond which we cannot retrieve or analyze information. Over the next 100 billion years, it is anticipated that stars beyond our Local Group will recede beyond the observable limit, casting an unsettling darkness over the night sky.

Dark energy represents an unyielding force of expansion. If intelligent civilizations exist in the cosmos, they would likely be aware of dark energy, regardless of its nomenclature. They would also grasp the urgency it presents.

According to the Kardashev Scale, a civilization's advancement can be gauged by its energy consumption and output, categorized into three types. Type One refers to harnessing the energy of one’s home planet, a feat humanity has yet to achieve. As civilizations progress, they might reach Type Two by utilizing energy from their own star, and eventually advance to Type Three by harnessing energy from surrounding galaxies.

Given that the universe is approximately 14 billion years old and humans have only inhabited it for about 200,000 years, it’s plausible that older civilizations exist elsewhere. Considering humanity’s rapid advancements over the last two centuries, it’s conceivable that a more advanced society could achieve Type Three status.

This advanced civilization, capable of utilizing stars from neighboring galaxies, would understand that dark energy is pushing cosmic bodies away. Their solution? They might reel in stars before they drift too far, securing energy for their ongoing expansion.

Though it may sound like science fiction, this concept is theoretically feasible through a proposed device known as a Dyson Swarm. Essentially a network of solar-powered satellites, a Dyson Swarm could capture a star’s energy and potentially adjust its orbit closer to a civilization’s home world. Scientist Dan Hooper suggested that such civilizations would require stars ranging from 20 to 100 times the mass of our sun.

As these stars are drawn closer, the energy output may generate detectable electromagnetic radiation. Galaxies that have been harvested would predominantly consist of massive stars, emitting longer wavelengths than expected.

While we currently lack the technology for such precise measurements, advancements in the coming years could enable us to detect these anomalies. The theory of utilizing dark energy as a beacon for extraterrestrial life is both captivating and warrants further exploration. The vastness of space makes accidental discovery of another civilization unlikely, especially as dark energy continues to expand the universe. Advanced civilizations would recognize this challenge and may leave behind identifiable traces of their efforts to mitigate its impact.
