From black technology to super engineering

Provincial capital, academician community.

It was February, and the heater in Huo Laien's house was also fully turned on, making it as warm as spring.

As a city that has been assigned to the south for a long time, the provincial capital has not had heating in the past few decades, but with the completion of controllable nuclear fusion, the use of waste heat has allowed the provincial capital to have a heating system like that of northern cities .

At present, the International Energy Organization has reached a consensus that the controllable nuclear fusion power station on the earth should be based on deuterium-tritium fusion reaction, supplemented by helium three reactors.

The premise of this consensus is that, on the one hand, deuterium-tritium fusion has achieved a huge breakthrough in tritium multiplication, reaching a self-sustaining recovery rate of more than 99.8%, and more importantly, helium-3 is currently the only fusion fuel for space travel—— Compared with the deuterium-tritium fusion engine, it is not only cheaper, but also safer, and it is also more suitable for building power stations in space.

After all, helium trifusion can be achieved without boiling water.

Therefore, utilization of waste heat from deuterium-tritium fusion reactors is a very important issue.

Mr. Huo Laien took the fruit plate from his wife, and then put it in front of Ye Ming: "Come and taste it, this is a fruit grown with the heat of the reactor."

There are mangoes, grapes, bananas and other tropical fruits in the fruit plate. Ye Ming smiled and picked up a grape and put it in his mouth: "Well, it's quite sweet."

"I heard that there is also a fruit planting base on the Asterisk?"

"Yes, there are not only fruit planting bases, but also breeding bases."

"Hmm..." Professor Huo Laien hummed, then looked at Ye Ming with a smile. After the latter ate a few grapes, he said softly: "If our theory is correct, we can disguise three-dimensional solid matter as information, and of course we can achieve precise instant communication through artificial wormholes, but it still can't cover us up. It is impossible to get rid of the status quo of wormholes."

Ye Ming picked up another banana and nodded slightly.

"As for the back of the wormhole, I hold the same point of view as you." After a few seconds of silence, Professor Hollein said in a slightly serious voice: "We really can't expect that behind every wormhole we jump through time and space is Safe, or there is no civilization, or civilization is terminated."

Ye Ming hummed again.

Professor Huo Laien thought for a few seconds before continuing: "We are now trying to confirm whether time is meaningful in high-dimensional space. It's a pity..."

Ye Ming said immediately: "I can't be sure."

"Yes, I can't 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, frowning slightly.

He was invited to his home by Mr. Huo just after he returned from Aerospace City. He must have known that this Mr. Huo had something to discuss with him, or something to discuss with him.

Moreover, he can probably guess what the old man is 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 considering the establishment of a coordinate system between different dimensions, and he is still feeling that if it can be done in his lifetime, then To die without regret.

Don't underestimate the establishment of the 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 increasing dimension and reducing dimension.

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 that her husband and Ye Ming looked a little bit overwhelmed at the same time, Professor Petunia smiled slightly, put down the teacups and sat to one side.

"What question can stump Professor Ye Ming?"

When she interrupted, Ye Ming raised his head, thanked Mr. Huo and then smiled, "The professor asked me to design a device that can teleport to any place. "

Professor Petunia works in economics and knows nothing about theoretical physics. She was taken aback when she heard the words, and then looked at her husband: "Your physics has developed to this level? Similar to the teleportation in the world of Harry Potter." surgery?"

"Hahaha, of course not!" Mr. Huo Laien laughed loudly: "We have a theoretical basis!"

Ye Ming also laughed. Seeing that Professor Petunia was confused, he picked up a blank piece of 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 then drew a circle on the other end.

"Professor Petunia, 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 Petunia nodded: "According to the principle of the shortest straight line between two points, it can move at the fastest speed while keeping the straight distance, right?"

"Yes. But, how fast is this fastest?" Ye Ming looked at Professor Petunia with a smile.

Professor Petunia was slightly taken aback, looking at the blank paper thoughtfully.

"The speed of this two-dimensional world is determined by us—now, I stipulate that it can move no more than 0.1 centimeters per hour."

Professor Penny hummed lightly, and immediately looked at Ye Ming: "This corresponds to the insurmountable speed of light in the three-dimensional world?"

"Yes." Ye Ming nodded with a smile: "Back to the paper, we now visually measure the distance between this point and its purpose to be 20 centimeters, so its minimum time is no less than 200 hours."

"Now, how many ways do we have to teleport this point to its purpose?"

Professor Penny was taken aback again. After all, she is also a professor, and her husband is a great physicist. How could she not understand anything? Hearing this, she immediately picked up the white paper, bent the paper, and aligned the dot with the circle.

"Is it possible to arrive in an instant?"

"That's right!" Ye Ming laughed: "This is the model of a wormhole, and the space is curved."

"Hmm..." Professor Petunia saw that her husband was also looking at him with a smile, so she knew that this was obviously not what the two of them were discussing. But after thinking about it, she still gave up: "Is there any other way?"

"There is another way, let's take this point..."

Ye Ming tapped a point on the white paper with a pen, and then quickly dropped the tip of the pen 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 space displacement, so as to move rapidly in the three-dimensional space, and finally return to the two-dimensional space The destination of the world."

Professor Huo Laien added: "Instead of our discussion, we want to send the three-dimensional spaceship to the four-dimensional spaceship, and then return to the designated three-dimensional place."

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 spaceship that enters the four-dimensional space can perform spatial displacement in an 'instant'."

"The second is, how do we determine that when the spaceship comes out of the four-dimensional space, its position is the destination we want in the three-dimensional space."

Professor Petunia: "...Okay, let's talk, call me if you need it."

Ye Ming and Professor Huo Laien looked at each other, 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 Time in our three-dimensional world has no perceptual meaning when displacement is performed."

Mr. Huo Laien was taken aback for a moment, and then joy rose in his eyes: "That is, in theory, as long as the coordinates are established, it is feasible?"

"Yes. Moreover, we also need to find a way to move in high-dimensional space—the displacement brought by the propeller 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?"

——Several years of research have made Mr. Huo know that he may be the person in this world who is most eager to figure out the dimensional universe, but...the one who really has a deeper understanding of the dimensional world and is more able to see 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 feels more and more powerless in energy and thinking, so that he often spends time in academic conferences Make a heuristic summary.

And the one who came closest to proclaiming the truth of the universe...

But I have always called myself an engineer...

Run to build those space cities, spaceships.

Yes, he admits it makes sense.

But is there more to it than figuring out the truth of the universe?

Isn't that a joke...

As long as Ye Ming is willing to focus on the dimension theory, he believes that maybe he will be able to see the day when "teleportation magic" will be realized.

Facing Professor Huo Laien's gaze, Ye Ming fell into a long silence.

After a while, he exhaled slowly.

"Professor, I know what you think. But... I still lack the tools."

"What tool?"

"A space metric." Ye Ming bit his lip and said softly: "In the past hundreds of years, those ancestors have created countless classic space metrics for us to explain the world and perfect the theory... but it also caused us trouble."

"To unify the coordinate systems of different dimensions, we need to establish a space metric that can adapt to any dimension." Ye Ming said, looking at Professor Huo Laien: "I once wanted to try, but I have limited energy, and secondly... …It's hard to verify engineering, so I'm hoping to find inspiration from alien civilizations."

"Looking at it now, the civilization of Canglan Planet...may not have touched this level of knowledge."

"You have actually completed the metric of the four-dimensional space, right?"

"Yes, but it cannot be used in three-dimensional space at present." Ye Ming nodded, regretfully said: "Now I lack the parameters to pass."

The old man thought about it, of course he thought about it too.

But as the old man said, this artificial wormhole still cannot get rid of the upper limit of the speed of light and the wormholes that exist in reality.

And those naturally occurring wormholes... are dangerous.

Regardless of the fact that the exploration of Canglan Star is in full swing, a manned scientific expedition team has even been dispatched there.

But everyone knows that this is actually a risk—the bet is that "the shells will not fall in the same crater", and the civilization that wiped out the Canglan Star will not come back to take a look when humans arrive at the Canglan Star.

However, what if?

Therefore, the Dalian Shipyard is now working at full capacity to build a Xun Xun that can generate high-dimensional space membranes to block the wormhole in the galaxy where the Canglan Star is located.

Anyone who has played RTS games knows that the first thing to do when opening a sub-mine is to block the road first.

Although space exploration is not a game, the defensive thinking is the same.

So... If the technology of "full image transmission" can be solved, it means that human beings will no longer have to worry about frequently traveling through wormholes or facing unknown wormholes.

The idea of ​​"man-made wormholes" he put forward in Aerospace City was already an unimaginable "great prospect" for ordinary people.

But if such arbitrary coordinate transmission could be achieved, it would be...

The ultimate dream!

"Moreover, I also think that if we want to establish the coordinate system of the entire universe, we must first figure out our universe. We don't even figure out the model of our universe now. How can we establish coordinates?" Ye Ming exhaled again, He looked at the white paper on the coffee table.

A dot and a circle on the white paper are very distinct and clear at a glance.

"Perhaps only by standing in a higher dimension can we recognize our three-dimensional world."

Professor Huo Laien nodded silently, and then looked at Ye Ming: "Maybe the detector is an opportunity? Otherwise, how many more detectors should we send to Gaowei?"

"Well... yes." Ye Ming paused: "If possible, maybe we can send a wormhole teleporter in."

Seeing that Mr. Huo's eyes lit up, Ye Ming immediately patched it up.

"but not now!"

——Now that Director Niu is rushing to the provincial capital, he needs to meet him in person and ask him to clarify in person how much money he needs to prepare.

It's not that the money can't be spent, or dare not be spent. But how do you say that? The landlord's family has no surplus food!

In the past few years, countless huge projects have been launched continuously, even if the productivity is liberated, the resources of the moon are obtained, and the energy problem is solved...

But the improvement of productivity still takes time.

The improvement of productivity, in addition to the establishment of those great super projects, must also be reflected in... people's livelihood!

You can't let the common people be 1B poor and still do construction in space, right?

There was no problem during the war, but there is no threat now!

Therefore, Director Niu was indeed a little anxious to get angry, it was all money!

You said, how dare he make any promises to Mr. Huo.

Then...after leaving Mr. Huo's house, Ye Ming immediately received a call from Director Niu, asking him to wait for him in the office.
