"According to the current level of technological development and the limitations of relevant policies and regulations, it is difficult for us to mine faith on a large scale on the earth. Now that the road to sinking has been blocked, the only option left for the company is to go overseas.
.”
Xu Mengyuan said, "Next, let Hephaestus introduce to you the basic theoretical knowledge related to interdimensional travel."
"I'm happy to oblige." The handsome mixed-race guy also found a chair and sat down, rubbing his hands and saying, "Where do we start? Well... you have heard of string theory, buddy."
"I've heard some."
"Very well, let me keep the story short. According to the eternal inflation theory proposed by Soviet physicists Alexander Velenkin and Andrei Linde, the universe we live in is like a bubble, composed of quantum fluctuations.
caused by.
"There are an infinite number of similar bubbles. They are constantly being created and dying, with no beginning and no end. To help you better understand this theory, you can imagine a bottle of Coca-Cola being shaken crazily, and one of the bubbles is where we are.
universe, and other bubbles are other universes.”
"Most of the time, our universe is stable and lonely, growing and expanding on its own, but sometimes we bump into other bubbles. We researchers call this phenomenon interference.
"Normally, interference is silent. Most creatures in the two universes cannot feel the interference at all. They neither know when it starts nor when it ends. Interference
It has almost no impact on the universe.
"Until the founders of the Third Age unlocked the secrets hidden behind those ancient myths, they discovered that we can use interference to travel to another universe. This technology is now also called advent."
"Adventure in the early days was a very, very dangerous thing. It was probably equivalent to sticking your head into a crocodile pool full of crocodiles. Because the Calabi-Yau manifolds are different, the physical rules of different universes are likely to be very different.
.
"Going to a universe with a different Calabi-Yau manifold is basically the same as committing suicide. Fortunately, there are enough bubbles. Later researchers, through trial and error, gradually developed the search method after paying an extremely expensive price.
approach to the same Calabi-Yau manifold universe.
"Then the filter conditions were further narrowed, and finally we selected new worlds that were similar to ours."
"What does "similarity" mean?" Li Yu asked.
"To quantify it, it is probably a world where the deviation is within 5%, with climate, geographical environment, animals and plants that we are familiar with... The most important thing is that classical physics is fully applicable." Hephaestus said, "We call it
These worlds are pure lands."
"But it's not enough to find the right plane and master the technology to descend," Xu Mengyuan interjected, "It's like you have set a destination and prepared a ship for sailing, but in the end you still need a person to pilot it.
it.
"——The captain is the key to all this."
"That's right, only a very small number of people in this world have the ability to cross the universe and descend from one universe to another." Hephaestus continued, "I dream of going to another universe, no matter the cost.
I won't regret it even if I die there in the next second, but I will never have that chance in my life."
The handsome mixed-race man sighed, looking very regretful, "Ordinary people like me are destined to rely on my poor imagination and your descriptions to feel its magnificence. I pray that I can meet it in my dreams."
.”
"That place is indeed quite beautiful," Li Yu said, "It's a bit like medieval Europe, with a little fantasy element added. The most powerful empire there was established by orcs, humans and dwarfs, but there is no magic and
Magician."
"Orcs? Like the ones in "Lord of the Rings" or..."
"It has animal ears, and its appearance is not much different from that of humans."
"Damn!!!" Hephaestus said a rare expletive, "The only thing in this world that I can't refuse is furry! Now a world full of furry is in front of me, but I can't take a fancy to it.
Even one glance, this is not fair! This is not fair at all!!!"
"We can discuss your sexual fetishes later." Xu Mengyuan looked at the time and said, "The next visit will start soon, so you'd better focus on the key points first."
"Okay." The handsome mixed-race man had to suppress the impulse in his heart, "Next, I will introduce to you a few rules related to Advent, but I believe you have already noticed some of them."
"First of all, you can bring things from this world with you."
"But only what my body can touch?" Li Yu said.
"Bingo! Wow, buddy, your observation skills are really good," Hephaestus praised, "And at this stage, the total weight of the things you can bring cannot exceed five kilograms. It cannot be alive.
Food, not even uncooked seeds.”
The words of the handsome mixed-race guy also explained why when Li Yu arrived for the first time, his cell phone, watch and clothes were all there, but the wallet and tissues in his pockets were missing.
Fortunately, the last two items were still in the room when he came back.
"What about germs?" Li Yu asked again. "It's impossible for the bacteria and viruses I carry to disappear with me. What impact will they have there?"
"This is a very interesting question. I have seen similar discussions on many forums before. I think most people have more or less overestimated the power of modern germs, although many people like to use the American continent's
Let’s take the Indians as an example.
"But these people ignore one premise, that is, the smallpox brought by European colonists is itself the most devastating infectious disease in human history. The same is true for influenza viruses, the Black Death, and the coronavirus that is now raging
,our old friend AIDS and so on...
"But if you are a healthy person, the germs you carry will have very limited impact on a similar new environment. In fact, long before the geographical discovery, Eurasians had arrived in the Americas.
The germs they brought didn't destroy it."
Seeing that Li Yu had no other questions, Hephaestus continued.
"Second, you cannot bring anything back from that world, whether physical objects or photos, and the time you can stay in that world at a time does not exceed seven and a half hours in real time.
"Of course, you must have realized that time flows at different speeds in different universes. Our seven and a half hours is not equal to the seven and a half hours over there..."
"Three to one." Li Yu said.
"What?"
"The time flow rate comparison between the two sides is almost three to one. The first time I came, I spent almost a day there."
"You went to a multi-time universe? That's good, it means you have more time to act. Although there is not enough research to prove why this is the case, your watch and phone will still display the real world
Time, make good use of this, and you will be able to seize the opportunity to return."
"Did the return happen naturally, or..." Li Yu asked again.
"It happens naturally. To that universe, you are like a guest. Once the reception time is over, you will be invited out of the house by the host."
