"The Einstein-Rosen bridge is a hypothesis based on general relativity. Although scientists had actually observed the existence of wormholes before the catastrophe, their observational conclusions also mentioned that their existence is a low-dimensional projection of a high-dimensional space."
Li Fengnian smiled and continued, "Unfortunately, this conclusion hasn't been professionally verified yet, and the catastrophe happened right before, so the conclusion itself is not authoritative. However, even so, we can still believe that the Einstein-Rosen Bridge is related to higher-dimensional space."
Chen Yan looked at Fei Changyuan, then at Li Fengnian, his small eyes filled with great confusion.
The other people in the small group were not much better than Chen Yan.
Including Xu Qinghe, the source of knowledge for everyone in the small group was taught bit by bit by Fei Changyuan.
The only difference is that Xu Qinghe only has Fei Changyuan to teach him, but with the addition of other people, Xu Qinghe, as the eldest brother, has to take on part of the educational responsibilities.
Even in a wasteland world, Fei Changyuan still believes that knowledge is indispensable.
Therefore, even though most of the survivors in the wasteland world can actually be classified as illiterate, these people in the small group have all received higher education!
Even the youngest child, Maomao, had already completed the knowledge education equivalent to that of a junior high school student before the outbreak of the Cataclysm.
But the shortcomings of this kind of teaching by example are very obvious.
Limited by Fei Changyuan's area of expertise, everyone in the small group has some specializations.
At least when it comes to knowledge related to theoretical physics, the people in the small group are basically on par with Chen Yan, and they are all at the level of having mastered nine out of ten things.
Facing these bewildered gazes, Li Fengnian shrugged his shoulders, spread his hands, and said, "One-dimensional space is a line. Two-dimensional space has the concepts of 'length' and 'width', forming a surface. Three-dimensional space has the additional concept of 'thickness', forming a three-dimensional space. Everyone understands this, right?"
Everyone in the small group, including Chen Yan, nodded.
Li Fengnian continued with a smile, "Very good. Based on the increasing relationship of three-dimensional space, we can draw a conclusion. Two-dimensional space is actually composed of countless one-dimensional spaces. Countless lines form a huge 'surface', which is two-dimensional space.
By the same token, three-dimensional space is composed of countless two-dimensional spaces. Countless "faces" form a vast three-dimensional space. So, theoretically, four-dimensional space should be composed of countless three-dimensional spaces stacked together.
The space we live in is just one of countless three-dimensional spaces. We are all three-dimensional beings, so naturally we can only live in three-dimensional space. If four-dimensional space really exists, we can only see a very tiny part of it in the three-dimensional space we live in.
The so-called Einstein-Rosen Bridge theory, in simple terms, is that scientists believe that higher-dimensional space can influence lower-dimensional space, thereby connecting two low-dimensional spaces that were originally extremely far apart. This is the theoretical existence of space folding technology.
Chen Yan and the people in the small group were still confused.
Seeing this, Li Fengnian covered his face with his hands and said helplessly, "Forget it, Chen Yan, just show it directly. Let's see how Chen Yan did it. Maybe we can get a clear conclusion."
Chen Yan nodded and walked straight to the small group's transport vehicle.
After being promoted to a level five awakener, the size of his portable warehouse has expanded to six meters in length, width and height, for a total of 216 cubic meters.
Even though there are still a lot of supplies piled up in the portable warehouse at this time, it is still possible to load another all-terrain transport vehicle.
So Chen Yan didn't play any tricks. He just waved his hand and put the transport truck into his personal warehouse on the spot.
The people in the small group and Li Fengnian only felt a flash before their eyes, and then they found that the transport vehicle in front of Chen Yan had disappeared out of thin air while they were watching intently!
What’s going on?!
That’s it?!
The square suddenly fell silent.
Except for Qin Yourong, who was not surprised, everyone else, including Li Fengnian and Fei Changyuan, stared with their eyes wide open.
No matter how high-tech it is...it shouldn't be this silent, right?!
"Xiao...Xiao Chen, where's the transport vehicle? Has it...has it been stored in the subspace using your space-folding technology?!"
Fei Changyuan asked blankly.
Chen Yan turned around and nodded, "That's right. If you want to take it, you can take it out at any time. Or if you just want to take a specific item instead of taking out the transport truck and everything on it, that's also fine."
Fei Changyuan instinctively exchanged a glance with Li Fengnian, and both of them saw the shock and confusion that was difficult to conceal in each other's eyes.
When the space folding technology was explained just now, Chen Yan still said that he didn't understand.
As a result, as the space folding technology was demonstrated, it was immediately their turn to express that they couldn't understand it.
Is this the law of nature, retribution?
"That shouldn't be the case... The presentation of any technology requires a corresponding medium, or what's known as an instrument. Space folding technology involves the core concepts of high-dimensional space in string theory and M theory. Presenting it would inevitably consume an incredible amount of energy."
Li Fengnian looked at Chen Yan with a puzzled look on his face and continued, "Although controlled nuclear fusion technology provides powerful energy support for many cutting-edge scientific theories, even for controlled nuclear fusion technology, providing enough energy to support high-dimensional interference is still a huge project.
I don't know much about this, so I don't know what reactor power is needed to meet the demand. But no matter how optimistic the predictions, the actual use of this technology shouldn't be so quiet... How did you do it?"
Chen Yan smiled bitterly and said, "To be honest, I really don't know. I only know that I have this ability. As for why I can do it and what the principle is... I can't explain it at all."
Li Fengnian was sure that Chen Yan was not lying.
However, this kind of "truth" made Li Fengnian instinctively start to have wild thoughts again.
Forcing your imagination is the most deadly!
"Forget it, if you don't understand, then you don't understand. This is not important. What's important is that Xiao Chen has indeed solved our biggest problem right now."
Fei Changyuan clapped his hands with a smile and continued, "In that case, there's no need to worry about anything else. Just wait quietly until night, and then we'll go together!"
