Why are there holes in the universe? Cheng Xuelei, a researcher at the National Astronomical Observatories of the Chinese Academy of Sciences, gave this explanation: In astronomy, a void refers to the space between filamentous structures. The Pen Fun Pavilion www.biquge.info void contains little or no galaxies. If we use a vivid metaphor to describe it, the universe is like a three-dimensional "fishing net", where the network lines are dense, a node is formed, and the density at the node is higher than that of other regions, so there is more matter at the node, and it is also the place where various stars, nebulae and other galaxies are born. And where the network cable is sparsely intertwined, there is a hole.

"It is not uncommon for there to be holes in the universe, and they have long been confirmed in astronomical observations!" A researcher at the Shanghai Planetarium said that the universe is usually composed of visible stars, gases and dust, and most of the matter in the universe is invisible and cannot be observed by the human eye. But why do astronomers know exactly where some of the matter in the universe exists? This is because they can make inferences based on the gravitational effects of matter observed in the universe. Astronomers have discovered cosmic holes, and the key is that in comparison, the previous holes were very small, and this time the size of the holes is indeed large.

Lawrence Rudnico, a professor of astronomy at the University of Minnesota, said: "The volume of the cavity discovered this time is 1,000 times the volume of the 'typical cavity' that we previously speculated. ”

The implications of discovering a giant void could upend the Big Bang theory

It is reported that this huge cosmic hole was known to Lunik and his colleagues when they examined the observation data after using the Very Large Antenna Array (VLA) radio telescope, and they found that the galaxies in this area are almost extinct, thus proving that it is indeed a cosmic giant hole. Lilia Williams, a teaching assistant involved in the study, said: "The results of this discovery are extraordinary, both based on observational data and computer simulations of the large-scale evolution of the universe. ”

So what is so unusual about this huge cosmic void? An expert in space physics at the Institute of Theoretical Physics of the Chinese Academy of Sciences believes that this huge hole is very likely to overturn the "Big Bang" theory. ---introduction

"This ...... You don't have to worry, your injuries will heal soon! ”

The wind didn't blush, he didn't pant for breath, and he pretended to be indifferent and said to Luna.

"Luna, you're finally awake, I'm scared!"

Linda, who was on the side, screamed for joy when she saw Luna wake up, and Catherine was also excited.

"Oh, by the way, this is Master Feng, if Master Wind hadn't appeared and solved a fiery lion, I'm afraid even we would not be able to escape the danger, and your injuries were also saved by Master Feng."

Seeing that Luna has been staring at the wind with strange eyes, Linda immediately introduces Luna.

"Thank you, Master, for saving your life!"

Luna lowered her head and thanked the wind with a blushing face, and at this moment, Luna's ears and neck were full of redness.

"It's nothing, I'm just seeing unevenness on the road and pulling out my sword to help!"

"When the road is uneven, draw a knife to help?"

After hearing the wind's words, Linda and the others couldn't help but be stunned, with a smile on their faces, and they couldn't help but have a good aftertaste.

After bandaging the wounds of Luna, who was flushed, the four of them sat there and chatted together, and Linda and the others, who had been rescued by the wind, were not wary of the wind, and after a while, the wind learned a lot from them.

The time and space that the wind passes through is called the Eryun space-time, the northwest of the space-time is the Caesar Empire that advocates magic, the southwest of the space-time is the Shenwu Empire that advocates martial arts, the center is the Proud Empire with highly developed commerce, and the southeast is the Caton Empire, which is roughly composed of these four empires.

In the northeast of time and space, is the Kasaramagan steppe where the orcs are located, and there are still some small countries in the middle of the four empires, but it does not have a significant impact on the situation in this time and space, and in the easternmost part of time and space, there is the vast Demon Domain Mountains, which are full of dangers, and there are demonic beasts everywhere, according to legend, the powerful dragon clan lives in the deepest part of the Demon Domain Mountains, and the east of the Demon Domain Mountains, but no one can know what exists there.

In the sea to the north of the Eryun space-time, there is a bitter cold and extremely cold land, the area is about one-fifth of the four empires, and the ice country is built on it, and the south of the Eryun space-time also has a land area of one-quarter of the Eryun space-time, the Krar Empire is built on it, and there is an island between the four empires and the Krar, the Dara Island Group.

This is the most basic layout of the entire Eryun space-time!

The mountain forest that the wind crossed is located on the eastern border of the Sith Kingdom, which is a medium-sized country, with the vast Demon Mountains to the east, the Caton Empire, one of the four empires, the sea to the south, and the desert beyond the northern border is the Kasaramagan steppe of the Orc Empire.

Roin and Lacey, who came back after half an hour, were also overjoyed to see Luna wake up, and they were even more grateful to the wind, but since herbal healing is not like magic, it takes a certain amount of time to work, so at the suggestion of the wind, Rin and Lacey made a stretcher for Luna.

Although Catherine was also traumatized and unable to fight for the time being, she was barely able to move forward.

When Luo Yin asked about his plans, of course Feng would not give up this good opportunity now, and he who incarnated as a space-time wanderer was left behind by Linda and others, and "reluctantly" stayed in the Blade Mercenary Group.

The Blade Mercenary Group originally entered the Demon Domain Mountain Range to hunt for some demonic cores, but now that this situation is no longer possible, it is obvious that it is no longer possible to continue the adventure, and under the leadership of Luo Yin, everyone went back along the road they came.

Because someone was injured, after two days of driving in the mountains and forests, they walked out of the mountains and forests, and after walking for half a day, a small town appeared in front of everyone's eyes.

Through understanding, Feng knew that this town was the town where Roin and the others set off, the northern border town of the Sith Kingdom - Green Town.

The town is bustling with people walking the streets, and there are very few ordinary people, most of them adventurers armed with weapons.

Due to its proximity to the dangerous Demon Mountains, Grimm existed as a rest stop for adventurers, and the rest of the merchants and adventurers who moved in later were all except for some of the natives of Grimm Village before it was developed.

Now the place where Roin and the others are going is the center of the town, the mercenary union!

Since Luna and Catherine's injuries were extremely serious, two days of hard work could not allow them to fully recover, so everyone went to the mercenary guild in addition to some tasks, and more importantly, asked the priest who lived next to the mercenary guild and the town to treat their injuries.
