Voyage of the Stars

People then move on to read the content of the information.

[Yes, if you are good at astronomy, you may have guessed that the place we are talking about is the Great Boötes Void, which is 700 million light-years away from our Milky Way.

We first thought that the local hole near our galaxy could achieve the goal, but we seemed to be wrong. After our scientists' calculations on the structure of dark matter, the local hole seemed not large enough, and it was very likely that it would not be able to eliminate the experimental impact...

We trusted our scientists' calculations, so we didn't choose a local void right next to our galaxy. Yes, it's a pity that there is such a close local hole but there is no choice. There is no way... The diameter of the local hole is only 150 million light-years, and it really doesn't meet the requirements.

Our scientists have calculated that on the huge cosmic scale centered on our Milky Way, perhaps only the Great Boötes Void is the most likely. With a diameter of 250 million light-years, it is the largest of many voids. If it is not suitable yet , maybe we have only one way to perish...]

Seeing this, all the humans on the First Fleet frowned. Of course they knew about the Great Boötes Hollow. It was a very huge area in the universe with almost no galaxies. It was one of the largest holes known to mankind.

The diameter of the hole is about 250 million light-years, which was discovered and roughly measured by humans in 1981. This hole is located in the direction of the constellation Boötes, about 700 million light-years away from the Earth, with an average of only one hole every 10 million light-years. A galaxy.

Because it is roughly in the direction of the constellation Bootes when viewed from the Earth, which is also the origin of its name.

To use an appropriate analogy to describe its size, if the Milky Way was located at the center of the Boötes void, humans would not discover the existence of other galaxies until the 1960s.

According to the distribution density of galaxies in the universe, there should be about 50 million galaxies in such a large area, but there are only 60 galaxies in the Boötes Void.

Some people believe that the Boötes void is formed by the merger of multiple small voids, just like small soap bubbles merging into one large soap bubble. This theory can explain why a few galaxies survive in a central tube-like area in the void.

The development of human astronomy is not bad, at least the estimation of the void of Boötes has been confirmed by the pioneers here.

In fact, for such a large hole structure, it is normal for the observation and calculation results to deviate from the actual result by tens of millions of light years.

This result is still data from the era of human Earth. Human beings have spent most of their time thinking about how to survive after setting foot in the starry sky. Most of the observations of the starry sky are within the Milky Way. It has been a long time since humans have focused on the scale of the large universe.

But now, the information left by the pioneers has once again directed humankind's attention to the vast and exhilarating universe.

After feeling silently in his heart, Yue Yuan once again looked at the message left by the pioneer.

[Oh no... Maybe there are other feasible ways. Maybe there is such a possibility. We will have to face the KBC Hollow by then. But if we really have to face the KBC Hollow, we are really going to die. It’s a last-ditch effort, because it’s impossible for us to get out of that two billion light-year diameter, and we will definitely not be able to get out if we go in...

Of course, we estimate that there are other civilizations that will go to other voids, such as the Fornax void, the Capricornus void, the Sculptor void, the Cygnus void, the Canis Major void, the Microscope void, the Corona Boreal void, and so on. 】

[Some civilizations may try their luck in these voids. After all, due to their location in the universe, some civilizations are still too far away from the Boötes void.

Just like some that were born in the Capricornus Supercluster, the Pisces-Cetus Supercluster, the Sculptor Supercluster, the Phoenix Supercluster, the Clock Supercluster, the Columba Supercluster, the Canis Major Supercluster, Peacock-Indian supercluster, Ophiuchus supercluster, Hydra supercluster, Coma supercluster, Perseus-Pisces supercluster, Sextant supercluster, Cepheus supercluster Civilizations such as clusters and other super-galaxy clusters may really choose these holes. We wish them success...]

[Of course, we believe that if possible, civilizations born in these super galaxy clusters will also give priority to the Boötes void.

Civilizations like ours that were born in the Virgo supercluster are still too far away. Perhaps some civilizations that were born in other nearby superclusters have already advanced like the Boötes void ahead of us.

For example, those civilizations born in the Cebu Supercluster, the Ursa Major Supercluster, the Corona Borealis Supercluster, the Shapley Supercluster, the Bootes Supercluster, etc., I don’t know if they have succeeded. 】

[In fact, we all know that entering a void is almost a dead end, because there are almost no galaxies there, and even if there are, they are extremely rare. Therefore, the biggest problem that a civilization that enters a large void will first face is matter.

Of course, there is matter and galaxies in the large void, but there is too little, and it is certainly not enough to support the material needs of all civilizations. Therefore, civilizations entering the large void will not only face the test of the harsh natural environment of the universe, but also countless dangerous civilizations. …

Of course, the prerequisite for facing these is to be able to reach the Great Hollow. The pioneers of our two civilizations are already the most powerful in the galaxy. We can no longer find any opponents in the galaxy, but even so, we can’t There is no guarantee that we can safely cross the 700 million light-year distance. 】

Yue Yuan and others looked at the information left by the pioneers, and they could not help but think of a great fleet that set out from the Milky Way and sailed across one galaxy after another.

They were all very good at science, so they naturally knew that the 700 million light-year journey mentioned by the pioneers was not actually more than 700 million light-years, because the fleet could not sail straight to the destination, but was just heading towards the target in the general direction.

During this period, it was necessary to follow the location of the galaxy, that is, the Great Route, just like when humans sail today, they use stars as stopovers to replenish materials, but civilizations like the pioneers use galaxies like the Milky Way as stopovers.

In this process, they will inevitably encounter strange and powerful civilizations, just like the awakeners came to the Milky Way, and perhaps they would be buried in a galaxy if they were not careful.

Didn't the pioneers say before that they destroyed a level 6 civilization from the Andromeda Galaxy before starting the Great Voyage?

Maybe that civilization was not the Andromeda Galaxy's original civilization, but a civilization that sailed from other galaxies and was killed in the Milky Way.
