Chapter 141: The Hidden Star and the Möbius Ring World

One of the primary reasons for choosing Sirius A (Water Commission One) was its massive size.

The universe is filled with numerous red dwarf stars, which are small and emit weak energy.

Yellow dwarf stars like the Sun are no longer sufficient for the Federation.

Hence, they sought a larger blue dwarf star as their capital star.

Despite their name, blue dwarfs generally have twice the mass of the Sun, with a typical example being Sirius, which Yan Xia had considered before.

Sirius has around twice the mass of the Sun and is relatively close to it, making it the brightest star visible to Earth's inhabitants.

However, Sirius is too close to the original capital star, Procyon, and could be affected by long-range weapons. Moreover, its mass isn't exceptionally large, so Ella dismissed it.

Sirius A has a mass approximately 6.7 times that of the Sun, and its companion star is also around twice the mass of the Sun. Together, this binary system has a mass nearly nine times that of the Sun, providing ample energy.

As a blue dwarf, Sirius A doesn't experience the volatile behavior of giant stars. Although it isn't entirely peaceful, it is a B-type emission star, with emission lines in its spectrum in addition to the usual absorption lines.

The emission lines are typically hydrogen lines, known as the 21-centimeter line, as its wavelength is around 21 centimeters, or more precisely, 21.10611405413 centimeters, falling within the microwave range and affecting electronic equipment.

These hydrogen electromagnetic spectral lines are produced by changes in the energy levels of medium-sized hydrogen atoms. Simply put, it occurs when the electron configuration or coupling mode within the atom changes, resulting in electromagnetic waves.

The hydrogen lines emitted by Sirius A are generally the H-alpha and H-beta lines from the Balmer series of the hydrogen atom spectrum, both of which are within the visible light range.

This doesn't imply that B-type emission stars only emit these two electromagnetic spectral lines. They can change rapidly within a short time, emitting other lines such as helium, singly ionized iron, magnesium, and more.

Such instability is challenging for a civilization entering the second level, like the Civilization Federation. However, they have now been at this level for almost 20,000 years, and Sirius A's instability can be suppressed or even utilized.

Both matter and electromagnetic waves can be converted into electromagnetic energy, and Sirius A's instability is beneficial for the Civilization Federation. As long as it doesn't collapse at any moment, the instability is manageable.

This time, Yan Xia didn't stop during his journey; he flew directly to Sirius A.

After exactly 1000 years of sleep, Yan Xia woke up and checked the external view from his spaceship, only to see nothingness. But soon, his spaceship broke through a barrier, and numerous oval-shaped, light blue stars appeared before his eyes.

These ovals were not the kind seen under a microscope but were visible to the naked eye.

Sirius A rotates rapidly at 250 km/s, about 8 to 9 times faster than the Sun. This results in an equatorial diameter of 1,586,880 km, while its polar diameter is only 1,016,160 km, a significant difference.

As Yan Xia observed Sirius A, he also noticed a white star next to it. Its whiteness wasn't a composite of the seven colors like the Sun but was inherently white in its spectrum.

This star was very close to Sirius A, at a distance of only 12 astronomical units. The two massive stars seemed almost intertwined.

"It's actually been realized."

A thousand years ago, Ella had told Yan Xia about a technology they were working on, named "Hidden Star," which was part of the Hidden Galaxy Project.

Since the False Starry Sky could already simulate the starry sky, why not surround the galaxy with it and hide the entire galaxy?

This technology required a massive investment, as it needed to lock down the entry and exit of light from all directions.

To achieve this, the False Starry Sky incorporated the "Wall" technology, creating an effect similar to the Purple Thorn Civilization's blockade of Proxima Centauri. However, it didn't completely seal off the galaxy but only blocked the entry and exit of electromagnetic forces.

Using this technology, Ella not only applied it to Sirius A but also to other galaxies, turning the Civilization Federation's star domain into a cosmic void.

Yan Xia couldn't help but feel suspicious; he wondered if the cosmic voids discovered by other advanced civilizations were also created by them.

With this technology, they could avoid the gravitational weapons of the Olive Branch Civilization.

After all, gravitational weapons aren't cheap; the Olive Branch Civilization wouldn't fire them without detecting the exact location of a star.

After such a long time, Sirius A has widely adopted the Dyson Cloud, although it isn't yet perfectly covered. It can be said that Sirius A's energy utilization has reached a high level.

Sirius A itself doesn't have any planets due to the proximity of the two stars, even closer than the Alpha Centauri binary system.

Ella utilized the technology of ring worlds to create land.

The ring world of Sirius A isn't two intersecting rings but a Möbius ring that encircles both stars, harnessing their energy.

This is an ingenious solution, but the resource consumption is far beyond that of the previous ring world. The surface temperature of Sirius A is a terrifying 15,000 degrees Celsius, so the ring world must be located far from the stars.

The circumference of the Möbius ring world is 4.7 billion kilometers, or 31.4 astronomical units, nearly 45 times that of the Domain of the Gods.

Its total area is more than 30,000 times that of the Domain of the Gods.

The amount of resources invested is so vast that the Möbius ring world is still under construction, with less than 5% completed. Even so, it is much larger than the Domain of the Gods.

Compared to the Domain of the Gods, which was already considered a giant structure, the Möbius ring world surrounding the capital galaxy of the Civilization Federation is like a small toilet.

After entering the "Hidden Star," Yan Xia's spaceship was towed to several ring-shaped devices with a diameter of 1000 kilometers. He initially thought they were deceleration devices, but they turned out to be acceleration devices. After ten accelerations, his spaceship's speed increased by 14.7% to 41,578.75 km/s.

As he approached the Möbius ring world, within 100 million kilometers, he encountered ten more ring-shaped devices, which were deceleration devices. These devices used gravitational constraints to slow down the spaceship.

The ten devices were spaced 8 million kilometers apart, and Yan Xia's spaceship was eventually decelerated to around 500 km/s.

Just under 1 million kilometers ahead was a starport, which towed his spaceship.

The entire experience was so comfortable that Yan Xia marveled at the advancement of technology.

Upon arriving, his life would once again return to tranquility.
