The loud and deafening music, the crazy swaying waist and hips...... The woman in the dark corner of the makeup teases the men who can't control themselves...... The ambiguous smell everywhere erodes and anesthetizes the pressure and deep pain that people face in real life......

As soon as Li Naixin and the others entered the nightclub, Wendy got on the dance floor, and Elusa stood by the wall of the nightclub with him, watching Wendy dancing to her heart's content.

"Beauty, you're dancing so well, may I give you a drink?"

A handsome scumbag hipster sticks behind Wendy, who is dancing to his heart's content, and says in a very magnetic ear.

"Okay~"

Wendy raised her neck charmingly, whispering like silk, causing the tide man to take her in his arms and walk straight to the bathroom.

"Hmm~"

Li Naixin, who was talking to Elusa about the perception of space, suddenly said: "Didn't you ask for a drink?

"What?" Elosha was listening to Li Tian talk about his space theory, but when she heard him say this, she couldn't help but be stunned.

Li Naixin didn't answer her, but closed her eyes slightly, and Elusa immediately stopped speaking. Because at this time, she already knew: Li Tian used her divine sense to check Wendy's movements, which is now often referred to as brain waves.

The lights leading to the bathroom were even dimer, and as soon as the tide man led Wendy out of the dance floor, he couldn't wait to press her against the wall and move her up and down. Although the rebellious Wendy has always longed for a passion, this is too different from her own reverie, right? She was about to open her mouth to shout, but was blocked by a mouth full of smoke and alcohol, so anxious that she desperately pushed the man on her body with her hands, but her strength was so insignificant.

Just when tears filled her eyes, Wendy saw a hand appear out of thin air and slash at the back of the hipster's neck, and the boomer man collapsed weakly. However, the hand that appeared in the air out of thin air did not stop there, but grabbed him by the collar and threw it hard into the crowd on the dance floor.

Suddenly, the hipster man who fell from the sky hit many people, causing the men and women on the dance floor to flee in an uproar, and one by one stood by the wall and talked about the hipster man who fell in the middle of the dance floor and vomited blood.

At this time, Li Naixin slowly got up and walked to the dance floor, Elusa looked at him in surprise, followed by him, and couldn't wait to whisper, "Could it be that you have also mastered the 'wormhole' technique?"

"Hmm~"

If it was before, Li Naixin really didn't understand what Elusa was saying, but now it is completely different! Li Naixin, who has been in the library of the University of Paris 1 for almost half a month, seems to be a knowledgeable scientific researcher.

The concept of "wormhole" was proposed by Austrian physicist Ludwig Flem in 1916 and perfected by Albert Einstein and Nathan Rosen in 1935. Therefore, the 'wormhole' is also called: the Einstein-Rosen Bridge.

The so-called 'wormhole' in people's mouths is the abbreviation of 'space-time wormhole'. It is considered to be: a possible 'shortcut' in the universe through which objects can be transferred in time and space in an instant; It is a narrow tunnel that may exist in the universe connecting two different time and space.

To put it simply, a 'wormhole' is a thin tube of space-time that connects distant regions of the universe. The dark matter in the universe keeps the wormhole exit open.

Wormholes can connect parallel universes to baby universes and offer the possibility of time travel. The universe is not infinite, but has a starting point in time, and at that starting point the Big Bang occurred, forming the current universe, which is about 13.7 billion years old, just like the infant period of human development, hence the name: infant universe.

The concept of the infant universe first establishes the idea of infinity, and in the infinite, we obtain (1+ environment) through the analysis of nature, and the environment contains infinite unknown space, space and life. In this 1, we define the concept of the baby universe. This universe, historically speaking, is not newborn, it also has a glorious history. Theoretically, the universe in which the white hole is located is the baby universe.

When a celestial body in our universe collapses to form a black hole, it is able to expand through the singularity at the center of the black hole into a different space-time. This space-time zone that expands from the singularity will be exactly equivalent to the expansion of our universe from the Big Bang singularity. Even if the amount of matter that entered the primordial black hole was only several times the mass of the sun, such a baby universe could skyrocket and become as large as our own.

It is likely that our universe collapsed in this way from a black hole in another space-time region, and the total structure of space-time (the 'total universe') is a series of interconnected bubbles, like a bubble on top of a glass of beer, with no beginning and no end. To illustrate this, we can imagine the space-time of our universe as the outer skin of an inflated balloon, from which the infant universe corresponds to a small piece that is squeezed out of the balloon and expands independently, and from the skin of the infant universe a new infant universe is generated like a bud, and so on, to infinity.

Another form of the infant universe: connecting to the parent universe via the Einstein Rosen Bridge.

A wormhole may also be a space-time tunnel connecting a black hole and a white hole, so it is also called a 'gray tunnel'.

Theoretically, a wormhole is a spatial tunnel connecting two distant space-times, like a whirlpool in the sea, which is ubiquitous but fleeting. These space-time vortices are caused by a combination of star rotation and gravity. Just as a whirlpool can bring a local water surface closer to the bottom of the water, two local spaces that are far apart can instantly get closer together.

In 1962, Robert Fuller and John Wheeler published a paper proving that wormholes are unstable if they connect two parts of the same universe. In 1963, New Zealand mathematician Roy Kerr proposed a hypothesis that regained theoretical support for the existence of 'wormholes'.

Like humans, stars go through the process of birth, aging, sickness and death, and Kerr believes that if stars can keep rotating as they approach death, they will form the 'dynamic black holes' we see in movies. When we launch an object along the axis of rotation as in the movie, if we can break through the gravitational field limit at the center of the black hole, we will enter the so-called 'mirror universe'. For example, the astronaut Cooper in "Interstellar", the 'extradimensional' space in the black hole can actually be regarded as an interpretation of the 'mirror universe'.

Entering the 'mirror universe' from the universe is itself a 'time travel'.

Some scientists have theorized that time does not move forward; On the contrary, everything that exists in time is eternal. According to this theory, if we could manage to 'look down' on the universe, we would be able to see time stretching out in all directions, just as we see space right now. At the time of the Big Bang, a 'mirror universe' was created at the same time, moving in the exact opposite trajectory of time from our own universe. And the highly intelligent species in both universes can realize that there is another universe that is working against them.

Therefore, wormholes can not only serve as a super-space-time conduit, but also manifest in the normal space-time of the universe.

The wormhole has no horizon, it only has a sub-interface with the outside world, through which the wormhole is connected in time and space. The interface between the wormhole and the black hole and the white hole is a space-time pipeline and the connection of two space-time closed regions, where the curvature of space-time is not infinite. As a result, we can safely pass through the wormhole without being destroyed by the huge gravitational pull.

What shocked Elusa was that Li Naixin could still pass through the wormhole with only a part of his body.

Looking at Li Naixin's back, Elusa felt that it was constantly magnifying, and she actually had a feeling of worship! But the next sentence suddenly made her feel fall to the bottom.

"Little Deflated Three~"

As he spoke, Li Naixin stepped on his life, twisted his foot, and blood stained his crotch......

"Ah~"

The tide man who had just been stunned by the handsome woke up again with severe pain.

Li Naixin then swung his sword fingers again, and several sword qi immediately cut off his hands and feet.

"Ah~ Murder!"

I don't know who suddenly shouted, and the nightclub, which was temporarily quiet because of the fall on the dance floor, became chaotic again, and the crowd fled everywhere. It's a pity that Li Naixin's sword fingers are frequent, and the sword aura is horizontal, and the men and women who want to escape from the scene are suddenly cut into several sections. But those who did not have time to flee were unharmed.

"Quack~"

"What do you want to eat?"

"Here are two of your specialties, a soup and a pot of rice. ”

"Okay~"

"Senior Brother Ming, it seems that you have adapted to life here!" Zhu Rongrong praised as Li Ming watched Li Ming and the restaurant guys talk fluently.

Li Ming said embarrassedly: "Senior sister, don't make fun of me! It's been more than ten days! If I still can't order a meal, I should really hit the wall and die!"

"Hahaha~ too!" Zhu Rongrong covered her mouth and smiled.

Restaurants, which are shops that sell food, meals, and snacks, can also be called 'restaurants' because they do not have alcohol; If there is a liquor shop, the smaller one is called: a wine shop or wine house, the larger one is called: a tavern, and the larger one is called: a restaurant; If you manage the meal, you can sell it, and if you can stay there, it is called: inn, also called inn.

"You two drink some water first, and your meal will be ready in no time!" The guy at the restaurant brought a pot of ordinary tea and a small plate of snacks and said, "Also, this is a free snack from our store." ”

After speaking, the guy was just about to leave, but he heard Li Ming say: "The guy asked you about something! How far is Qingyu City from here?"

"This son, don't you also want to go to the Immortal Mansion 'Drunken Immortal Residence'?" the guy asked in surprise.

"Yes!" Li Ming looked at the guy's surprised expression and asked puzzledly, "What's the matter?"

The guy persuaded him with good words: "Childe, I think you'd better not go and join in the fun!
