It was February, and the heating in Huo Laien's house was turned on fully, making it as warm as spring.
As a city that has long been assigned to the south, the provincial capital has not had heating in the past few decades. However, with the completion of controllable nuclear fusion, the use of waste heat has allowed the provincial capital to have the heating system of northern cities.
.
At present, the International Energy Organization has reached a consensus that controllable nuclear fusion power stations on earth should be based on deuterium-tritium fusion reactions, supplemented by helium III reactors.
The prerequisite for this consensus is not only that deuterium-tritium fusion has made a huge breakthrough in tritium reproduction, reaching a self-sustaining recovery rate of more than 99.8%, but more importantly, helium-3 is the only fusion fuel for space travel at present——
Compared with deuterium-tritium fusion engines, it is not only cheaper, but also safer and more suitable for building power stations in space.
After all, helium fusion does not require boiling water.
Therefore, the utilization of waste heat from deuterium-tritium fusion reactors is a very important issue.
Mr. Huo Laien took the fruit plate handed over by his wife, and then placed it in front of Ye Ming: "Come and have a taste. This is a fruit grown with reactor heat."
There were mangoes, grapes, bananas and other tropical fruits in the fruit plate. Ye Ming smiled and picked up a grape and put it into his mouth: "Well, it's quite sweet."
"I heard that there is also a fruit growing base on the Qingxing?"
"Yes, there are not only fruit planting bases, but also breeding bases."
"Hmm..." Professor Huo Laien hummed, and then looked at Ye Ming with a smile. After the latter had eaten a few grapes, he said softly: "If our theory is correct, we can disguise three-dimensional solid matter
Although accurate artificial wormhole instantaneous communication can be achieved by generating information, it still cannot conceal the fact that we cannot get rid of wormholes."
Ye Ming picked up another banana and nodded gently.
"I hold the same view as you about the backside of wormholes." After a few seconds of silence, Professor Huo Laien said slightly seriously: "We really can't expect that behind every wormhole where we jump in time and space.
Safe, or there is no civilization, or civilization has been ended."
Ye Ming hummed again.
Professor Huo Laien thought carefully for a few seconds and then continued: "We are now working hard to confirm whether time is meaningful in high-dimensional space. It is a pity..."
Ye Ming immediately said: "Can't be sure."
"Yes, it's impossible to be sure. But what do you tend to think?" Mr. Huo looked at Ye Ming, his eyes full of expectation.
Ye Ming put down the banana and frowned slightly.
Just after he returned from Space City, he was invited to his home by Mr. Huo. He must have known that this old man had something to discuss with him, or to discuss issues with him.
Moreover, he could probably guess what the old man was thinking.
In the past few years, the old man has been committed to the research of high-dimensional space - to be precise, the old man has been thinking about establishing a coordinate system between different dimensions. He even laments that if he can do it in his lifetime, then
Die without regrets.
Don't underestimate the establishment of this coordinate system between different dimensions - it is not a purely mathematical model, but a theory with practical significance, even great practical significance!
Because once the coordinate system is established, it means that the position can be moved instantly through the operation of dimensionality increase and dimensionality reduction.
But before that... the meaning of time needs to be determined.
At this time, Professor Petunia walked into the living room with two cups of tea. Seeing her husband and Ye Ming looking a little anxious at the same time, Professor Petunia smiled slightly, put down the tea cup and sat down to one side.
"What problem can stump Professor Ye Ming?"
When she interrupted, Ye Ming also raised his head, said thank you and looked at Mr. Huo before smiling and said: "The professor gave me a difficult problem and wanted me to design a device that can teleport to any place.
"
Professor Penny works in economics and knows nothing about theoretical physics. She was startled when she heard this, and then looked at her husband: "Has your physics developed to this extent? It's similar to the teleportation in the Harry Potter world.
Technique?"
"Hahaha, of course not!" Mr. Huo Laien laughed loudly: "We have a theoretical basis!"
Ye Ming also laughed. Seeing that Professor Penny was confused, he picked up a piece of white paper under the coffee table. Upon seeing this, Professor Huo Laien immediately took out a pen and gave it to him.
Ye Ming quickly drew a small dot on one end of the white paper and a circle on the other end.
"Look, Professor Penny, let's assume that this side of this white paper is a two-dimensional world. And this point is the spaceship in the two-dimensional world, and its destination is this circle."
Professor Penny nodded: "According to the principle of the shortest straight line between two points, it can move at the fastest speed while maintaining a straight line distance, right?"
"Yes. But, what is the fastest speed?" Ye Ming looked at Professor Penny with a smile.
Professor Penny was slightly startled and looked at the white paper thoughtfully.
"The speed of this two-dimensional world is determined by us - now, I will stipulate that it cannot move more than 0.1 centimeters per hour."
Professor Penny hummed softly and immediately looked at Ye Ming: "Does this mean that the speed of light in the three-dimensional world cannot be exceeded?"

"Yes." Ye Ming nodded with a smile: "Back on the paper, we now visually estimate that the distance between the point and its purpose is twenty centimeters, so its minimum time is no less than 200 hours."
"Now, how many ways do we have to make this point move to its destination instantly?"
Professor Penny was startled again. After all, she was also a professor, and her husband was also a great physicist. How could she not understand at all? After hearing this, she immediately picked up the white paper, bent the paper, and aligned the small dot with the circle.
"Does this mean we can arrive instantly?"
"That's right!" Ye Ming laughed: "This is the model of a wormhole, space is curved."
This chapter is not over, please click on the next page to continue reading! "Well..." When Professor Penny saw her husband looking at her with a smile, she knew that this was obviously not what the two of them were discussing. But after thinking about it, she gave up.
He said: "What other way is there?"
"The other way is that we take this point... up."
Ye Ming tapped a point on the white paper with his pen, and then quickly placed the pen tip in a circle twenty centimeters away.
"Just put it in again."
"This is to upgrade the two-dimensional spaceship to the three-dimensional space so that it does not follow the upper limit of the speed of the two-dimensional world - to be precise, the upper limit of the spatial displacement, so that it can move quickly in the three-dimensional space, and finally return to the two-dimensional space.
The world’s destination.”
Professor Huo Laien added: "What we are discussing is that we need to send the three-dimensional spacecraft to the fourth dimension, and then return to the designated location in the third dimension."
Professor Penny: "What's the difficulty now?"
"There are two difficulties now. The first one is that we are not sure whether the time in the four-dimensional space has nothing to do with the three-dimensional space. In other words, whether the spacecraft entering the four-dimensional space can undergo spatial displacement in an 'instantaneous' time."
"The second one is how do we determine that when the spacecraft comes out of the four-dimensional space, its position will be the destination we want in the three-dimensional space."
Professor Penny: "...Okay, you guys can chat, call me if you need anything."
Ye Ming and Professor Huo Laien looked at each other and then laughed.
…
"Professor, if you ask me, I tend to think that three-dimensional time is meaningless in four-dimensional space." After laughing, Ye Ming replied cautiously: "Or to be more precise, when a three-dimensional object is in four-dimensional space
When displacement occurs, time in our three-dimensional world has no perceptual meaning."
Mr. Huo Laien was stunned for a moment, and then joy rose in his eyes: "That means, in theory, it is feasible as long as the coordinates are established?"
"Yes. Moreover, we also need to find a way to perform displacement in high-dimensional space - the displacement caused by the thruster has no meaning in four-dimensional space."
Professor Huo Laien nodded heavily and looked at Ye Ming with burning eyes: "So, Ye Ming, what are you waiting for?"
——After several years of research, Mr. Huo realizes that he may be the person in the world who is most eager to understand the dimensional universe, but... he really has a deeper understanding of the dimensional world and is better able to realize his wishes...
He knew very well that this person should be Ye Ming.
The professor knows that time is one of the most irresistible physical properties. In the past two years, as he grows older, he has increasingly felt that his energy and thinking are insufficient, so that he now spends most of his time in academic conferences.
Make a heuristic summary.
And the person closest to revealing the truth of the universe...
But I have always thought of myself as an engineer...
Go and build those space cities and spaceships.
Yes, he admits that these are meaningful.
But is it more meaningful than figuring out the truth about the universe?
Isn't that a joke...
As long as Ye Ming is willing to focus on dimensional theory, he believes that he may be able to see the day when "teleportation magic" is realized.
Facing Professor Huo Laien's gaze, Ye Ming fell into a long silence.
After a moment, he slowly exhaled.
"Professor, I know what you are thinking. But...I still lack the tools."
"What tool?"
"A spatial metric." Ye Ming bit his lip and said softly: "In the past hundreds of years, those ancestors created countless classic spatial metrics for us to explain the world and improve the theory... but they also caused us
trouble."
"To unify coordinate systems of different dimensions, we need to establish a spatial metric that can adapt to any dimension." Ye Ming said and looked at Professor Huo Laien: "I once wanted to try, but firstly, I had limited energy, and secondly...
...It is difficult to verify from an engineering perspective, so I hope to find inspiration from alien civilizations.”
"Now it seems that Blue Star's civilization...may not have been exposed to this level of knowledge."
"You have actually completed the metric of the four-dimensional space, right?"
"Yes, but it currently cannot be used in three-dimensional space." Ye Ming nodded and said regretfully: "Now I lack the parameters to pass."
Of course he also thought about what the old man thought.
But as the old man said, this kind of artificial wormhole still cannot escape the upper limit of the speed of light and the wormholes that exist in reality.
And those naturally existing wormholes... are dangerous.
Not to mention that the exploration of Blue Star is in full swing, and a manned scientific expedition team has even been dispatched there.
But everyone knows that this is actually a risk - the bet is that "cannonballs will not fall in the same crater", and the civilization that wiped out the Blue Star will not come back to take a look when humans arrive at the Blue Star.
However, what if?
Therefore, the Dalian Shipyard is now working hard to build a star seeker that can generate a high-dimensional space membrane to block the wormhole in the galaxy where the Blue Star is located.
Anyone who has played RTS games knows that the first thing to do when opening a branch mine is to block the road.
Although space exploration is not a game, the thinking of defense is the same.
So...if the technology of "full image transmission" can be mastered, it means that humans will no longer have to worry about frequently traveling through wormholes or facing unknown wormholes.
The "artificial wormhole" idea he previously proposed in Space City is already an unimaginable "great prospect" for ordinary people.
But if such arbitrary coordinate transmission could be achieved, it would be...
The ultimate dream!
"Furthermore, I also think that if we want to establish the coordinate system of the entire universe, we must first understand our universe. Now, we don't even understand the model of our universe. How can we establish coordinates?" Ye Ming exhaled again,
He looked at the white paper on the coffee table.
A point or a circle on the white paper is extremely clear and clear at a glance.
"Perhaps only by standing in a higher dimension can we understand our three-dimensional world clearly."
Professor Huo Laien nodded silently, then looked at Ye Ming: "The detector, maybe it is an opportunity? Otherwise, we can send a few more detectors to high dimensions?"
"Well... ok." Ye Ming paused: "If possible, maybe we can send a wormhole teleporter in."
Seeing Mr. Huo's eyes light up, Ye Ming immediately patched it up.
"but not now!"
——Now that Director Niu is on his way to the provincial capital, he needs to meet him in person and ask him to explain clearly how much money he still needs to prepare.
It’s not that you can’t spend this money or don’t dare to spend it. But how do you say that? The landlord’s family doesn’t have any surplus food!
In recent years, countless huge projects have been launched, liberating productivity, obtaining moon resources, and solving energy problems...
But improving productivity still takes time.
The improvement of productivity must not only be reflected in the establishment of those great super projects, but also be reflected in... people's livelihood!
You can't let the common people be as poor as 1B and still carry out construction in space, right?
There was no problem during the war, but there is no threat now!
Therefore, Director Niu, or the highest decision-making level of the country and even the entire human race that he represents, is indeed a little anxious to get angry.
Tell me, how dare he make any promise to Mr. Huo.
Then... just after leaving Mr. Huo's house, Ye Ming immediately received a call from Director Niu, asking him to wait for him in the office.
