The Local Group is quite enormous.
Its diameter exceeds 10 million light-years.
But in reality, it is also incredibly tiny.
There are undoubtedly only two largest galaxies.
The Milky Way and the Andromeda Galaxy.
These two galaxies combined exceed 2.5 trillion solar masses.
The slightly smaller ones are the Large Magellanic Cloud and the Triangulum Galaxy, one with 10 billion solar masses, and the other with 50 billion solar masses.
Even smaller, like the Small Magellanic Cloud, has only 7 billion solar masses.
This is already quite strained to supply a Tier 3 Civilization, and it is even insufficient for multiple top Civilizations to coexist.
It is essentially certain that these Civilizations will come into Contact with each other, Yan Xia asking this question was merely to confirm it further.
“The eighth question: What is the upper limit of the highest Civilization in the Virgo Supercluster?”
“Actually, you should ask me about the Laniakea Supercluster; that is a higher-level structure. Even what you refer to as the Local Group is not a structural body in our eyes.”
“But it doesn’t matter, because these answers are negative. Even if we Contact many more Civilizations, there are still barriers between Civilizations themselves. I believe you also know the importance of information; no Civilization would tell us these things.”
“But if a super Civilization truly exists, then it must be at the Great Attractor. As far as we know, that is not a black hole, but a secondary universe.”
Secondary universe.
It is actually different from a sub-universe.
A sub-universe is essentially another description of subspace by Human Civilization.
It is not a professional term.
A secondary universe is.
Just like its name, it is a truly independent universe.
This is actually an extension of the Bubble Universe hypothesis.
The Bubble Universe hypothesis is a parallel universe hypothesis derived from the cosmic inflation theory.
All universes are individual bubbles, and beyond our universe, there are other universe bubbles different from our own, possessing completely different rule systems.
Based on dimension exploration, scholars of Human Civilization have gone a step further.
Since space can overlap, is it possible that some universe bubbles themselves overlap with our universe?
This is the 【Our Universe Secondary Universe Hypothesis】.
And overly massive black holes are often encompassed by this hypothesis.
The Great Attractor, a giant gravitational source, the Great Attractor at the core of the Laniakea Supercluster itself may have a mass hundreds of times that of the Milky Way, plus external factors, creating a gravitational effect tens of thousands of times greater than the Milky Way’s mass.
Because the distance is too vast, Human Civilization still does not know what exactly exists there.
And the Petrochemical Civilization gave a simple and direct answer to this Civilization.
A secondary universe.
The secondary universe Contacts our universe, creating a huge spacetime tunnel. This spacetime tunnel is similar to a black hole, or can be said to be a black hole, but unlike ordinary black holes, through it, one can reach the secondary universe.
This is still somewhat different from the principle of the Dimension Channel, and it is even more difficult.
“Does a Tier 4 Civilization exist in that place?”
A single Milky Way is tens of trillions of solar masses, which can probably support a Tier 3.2 Civilization.
The energy triggered by a single Great Attractor can support a Tier 3.4 Civilization.
It is hard to imagine what level a Civilization that controls the Great Attractor, then controls the secondary universe, and also the Laniakea Supercluster, would be at.
The Petrochemical Civilization creature shook its head.
“I don’t know, and besides, this is another question.”
“The ninth question, regarding the Light Civilization. The Light Civilization is a very ancient Civilization; it originated in the Milky Way and was once one of the dominators of the Milky Way, but due to an event, they left the Milky Way.”
“It was not other Civilizations in the Milky Way, but a more distant existence. The Light Civilization believes that supermassive black holes hide a great terror. What exactly it is, no Civilization knows, except for themselves.”
“This counts as a prophecy.”
“At the same time, it can also answer your tenth question, the Mirror Civilization.”
“By asking this question, I think you have already noticed that the Mirror Civilization cannot be a weak Civilization; they might not even be a Civilization, but merely a creation, a weapon.”
“Tens of millions of years after the Light Civilization left the Milky Way, the seed of the Copy Civilization was cast into the Milky Way through the Silver Heart black hole, causing a catastrophe within the galactic bulge.”
“Many Civilizations believe this was the first time, but we, the Petrochemical Civilization, know that the Copy Civilization’s ambition to expand has existed for an even longer time, even before our birth.”
That would be hundreds of millions of years ago.
“What you call the Mirror Civilization is their seed weapon, which grows by parasitizing and replacing Civilizations.”
“They not only covet the powerful Civilizations of the Silver Heart but also want to control all Civilizations. They should be a Civilization similar to your Human Civilization, but more aggressive.”
Similar.
That is to say, the Mirror Civilization is a Civilization collective, not a single Civilization.
Aggressiveness means that all Civilizations of the Mirror Civilization are not voluntary; in fact, they only want the Civilization itself, not the creatures of the Civilization.
“Ten questions have been answered.”
“I will remain here until you deliver all the planets, and at the same time, answer your remaining ninety questions.”
The voice of the Petrochemical Civilization life gradually became softer; it entered a state of dormancy.
In fact, the Petrochemical Civilization itself does not have a real Civilization system; all their Civilizations are built upon illusion. The so-called sleep is entering their own illusory world.
Yan Xia also left directly.
These answers were enough for him to digest for a while.
In fact, he still had many questions.
However, asking them now would undoubtedly be a waste.
From this transaction, it can be inferred that the Petrochemical Civilization indeed knows a lot of information.
“According to the information from the Petrochemical Civilization, it can be inferred that the Contact Civilization’s so-called desire to unite the Three-Dimensional is a complete lie.”
“The truth is, they merely hope to gain intelligence and prepare their retreat by controlling the Civilizations on the galactic disk.”
“After all, the retreat of other dimension Civilizations cannot be in the Three-Dimensional either.”
“Therefore, the greatest threat to Human Civilization has never been Civilizations from other dimensions, but those failures at the Silver Heart right now.”
Yan Xia did not ask about the Contact Civilization.
Because this information had already been confirmed from the Crystalline Civilization.
Qiaotuo Fen had intentionally or unintentionally mentioned this part of the information, and the Crystalline Civilization replied that it was impossible to know which Civilization the so-called Contact was based on such partial information.
The Petrochemical Civilization is only ancient, not omnipotent; it is impossible for them to know this information.
“Given the current situation, it is impossible for the Contact to give up monitoring Human Civilization, so where are they?”
This was Yan Xia’s question.
He could not judge now and could only hand over all this information to Ella.
