Abnormal crossing

Chapter 95 It's really big
Two days later.

"Is this the Blue Bridge Galaxy?"

Looking at the deep yet ordinary starry sky outside the window, Gu Wei's expression showed a hint of disappointment amidst his expectation:

"It doesn't look like anything special. I thought there would be some unusual phenomena in a galaxy with this name."

Just as Gu Wei said.

At this moment, although the scene outside the starry sky still made him, an Earthling, a little excited, this emotion was more derived from the curiosity of the Earth's "natives" about the universe, rather than the shock brought about by some strange phenomenon.

He originally thought that the Blue Bridge Galaxy would be similar to the green scarf-like magnetic reconnection belt he had seen before, with some special phenomena of its own - for example, it looked like a blue bridge on a certain scale, etc.
"You're overthinking this." Today, Mee Mee changed into a pyramid-shaped skin, floating around Gu Wei. "The name of the Blue Bridge Galaxy comes from the most powerful civilization when the galaxy was incorporated into the alliance. That civilization used some high-strength blue alloy to build a space bridge to the nearest satellite during the planetary period. After the bridge was built, they regarded it as a spiritual symbol, so the entire civilization called itself the Blue Bridge."

"In fact, if you think about it, you will know that celestial phenomena often represent 'instability'. Such areas are not suitable for transformation into garbage stations or placement of other important hubs."

Gu Wei touched his chin and said, "I see."

It is indeed very common to use some kind of wonder as a symbol of civilization. For example, Egypt on Earth is called the Pyramid Civilization by many people, and ancient China is generally considered to be a combination of the Yangtze River Civilization and the Yellow River Civilization, and so on.

If the S3 war had not broken out on Earth and the Earth had developed smoothly into the interstellar era, it might have been referred to by some giant project instead of "Earth".

Then Gu Wei paused, and a wave of curiosity emerged in his heart: "By the way, Meimei, how did the Blue Bridge civilization develop into a garbage station?"

"It's the alliance's decision," Mee Mee said lightly, "There are almost no black holes or pulsars in the Blue Bridge Galaxy, and the radiation and gravitational effects are very weak. Or in other words, very balanced. In addition, the dark matter field in the galaxy is evenly distributed, and the content of interstellar impurities and dust is also very small, which means that there will be no heating or decomposition caused by friction."

"This first-generation galaxy cannot be said to be a single copy in the universe, but it is still much less common than first-generation stars. If you add the remote location, it will be even harder to find - a garbage dump can't be set up in a busy area, right?"

Gu Wei was stunned.

what?
The Blue Bridge Galaxy is actually the first generation of galaxies?
mentioned earlier.

According to modern cosmological theory, the Big Bang created the universe 138 billion years ago.

For a period of time after the birth of the universe, there was darkness everywhere. It was not until 1 million to 2 million years later that the first generation of ancient stars appeared and emitted the first ray of light that illuminated the universe.

The first generation of stars dominated the production of the first metallic elements in the universe and provided the main energy for the cosmic reionization process.

Before Gu Wei traveled through time, the astrophysics community on Earth had only found some clues or candidates for the first generation of stars.

For example, the GN-z11 found by the Americans, and the LAMOST J1010+2358 discovered by the rabbits.

By the way, the sun above our heads belongs to the third generation of stars - well, the third generation, what a coincidence, isn't it?

And compared to the first generation of stars, the first generation of galaxies are even more fuzzy.

Because the early universe could only form two types of stars: massive stars and quasars. The latter is a structure formed by the direct compression of nebulae by gravity, and massive black holes quickly absorb the surrounding high-density nebula matter and continuously emit gamma rays. Among them, the dense and violent gamma-ray bursts of quasars will blow away the star clusters trying to form galaxies. Therefore, compared with the first generation of stars, the first generation of galaxies were formed later, but they are more difficult to find.

And it's interesting.

The first generation of galaxies with the highest probability before Gu Wei traveled through time was the product of a joint effort between China and the United States. The American Webb telescope released a set of data collected by a near-infrared spectrometer, in which the rabbits discovered a galaxy containing a strong ultraviolet radiation source and used photoionization to simulate the characteristics of this galaxy, playing a trick of using someone else's chicken to lay eggs.

"." Then Gu Wei looked out the window again and continued to ask Meime: "What about the Blue Bridge civilization? They are also a galaxy-level civilization after all, so why didn't they refute the resolution?"

"That's the decision of the Galaxy Alliance. How can we protest so easily?" Mee Mee glanced at Gu Wei. "Besides, who told you that the Blue Bridge Civilization is a galaxy-level civilization? They are just the most developed one in the Blue Bridge Galaxy. When the Blue Bridge Civilization joined the Alliance, there were only seven civilizations in the entire galaxy. In addition to the Blue Bridge Civilization, which has more than 300 star systems, the other six civilizations have not even set foot on a planet."

"As I said, looking at the entire galaxy, there are countless civilizations, but when you reduce the scale to reality, most naturally developed galaxies only have a few civilizations. Some galaxies may not even have any civilizations at all."

This time Gu Wei said nothing.

Then MeeMee paused and changed the topic to the specific structure of the Blue Bridge Galaxy:
"So far, the entire Blue Bridge Galaxy has set up more than 15.3 million primary garbage recycling points that allow outsiders to enter the 'Taobao'. Each primary recycling point is about the size of thousands of star systems, and is divided into hundreds to tens of thousands of nodes, which are planets that capture garbage."

"At the same time, each primary garbage collection point has a main channel for entry and exit, and the collection points are connected by small jump points. This is only the area that the Blue Bridge System allows outsiders to enter. Outsiders cannot enter any other areas even if they want to."

Upon hearing this, Gu Wei showed a hint of surprise in his eyes.

Also.

According to the data he found on the Internet platform, the short axis span of the Blue Bridge Galaxy is 8.7 light-years, and the long axis spans 46.9 light-years. The volume of the entire galaxy is approximately 5.213 times that of the Milky Way.

The Milky Way can accommodate 1000-2000 billion star systems, so the Blue Bridge Galaxy can naturally accommodate more.

Even if the 10 million recycling points mentioned by MeeMee are multiplied by the single-point capacity of , the total number of star systems converted by this part is only more than billion, which may not even reach % of the upper limit of the galaxy.

Think of this.

Gu Wei couldn't help but recall a well-known online novel that he had been rereading before traveling through time.

The content of that novel is undoubtedly classic to the extreme, and the writing style can crush Gu Wei into dust, but when describing the so-called big world, the words used are only [1 billion planets] - this scale cannot even cover % of the Milky Way in the universe.
It’s not that there’s something wrong with that great god’s imagination, but that the universe is simply too huge.

When you write, you think that a certain number is very exaggerated, but in the real universe, it may not even be as big as a sesame seed.
The reason why astronomical figures are called astronomical figures is because they often exceed the human cognitive framework and are incredibly large.

And at the same time Gu Wei was chatting with Meime.

Milo on the main console also raised his head and asked a question to the main thread of MeeMee:
"Mee-mee, where are we now?"

Note:
Something happened at home, it was a mess, my uncle went straight to the hospital to ask why grandma didn't die, I'm sorry for the lack of updates in the past two days
