Cao Chuan's home is now a lot more lively because of the new two lolis, but these days, in order to try to solve the problems encountered so far before the fifth batch of support leaves, he basically has no time to enjoy the pleasant time of leisure.

Of the three remaining questions raised by Professor Russell so far:

The first problem, the communication puzzle, is successfully solved by quantum entanglement communication devices.

The second problem, that the interstellar speed is too slow, is successfully solved by the jump spacecraft.

The third problem, deep space observation, is to be done by himself, and he plans to make a deep space radar.

What they need is not what happened in a few astronomical units around them a few hours ago, which is something that cosmologists are interested in knowing, but as businessmen, as captains, as mayors of cities, they want to know what is happening at least 10 units away, at this moment and second.

"So, so far, there are probably a few solutions." Cao Chuan said to the 3 loli below, don't look at their thinking and consciousness seem to be busy, they are all working everywhere, busy making such a big machine as the East Galaxy Company work, her human body is actually idle, in addition to eating and sleeping every day, plus everyone's own entertainment activities, Cao Chuan feels that it is also a good idea to let them take on some work.

Accompany their owners through this difficult time! When he said his thoughts,Sure enough,3 Lori agreed without hesitation.,After all, it's the master's request.,If you don't obey the master, you'll be angry.。

Cao Chuan taught like a teacher: "The first direction is still the path of light observation, because the light has to walk for 8 minutes to pass the distance of 1 astronomical unit, how do we know what is happening at the moment outside 1 astronomical unit?" At this time, we can use the method of computer deduction, according to the orbit of the planet, to calculate where it will be in 8 minutes, so that we can know its current position. ”

"But. This only makes sense for objects that move regularly, and for ships in battle, their position can be random at any given moment; Also, suppose it's a material that absorbs light, or even absorbs electromagnetic waves, then. We will be helpless about it. ”

"So it's not a long way to go."

"The second is quantum entanglement communication. Suppose our spacecraft has a pair of eyes that are located in space 10 astronomical units outside of the spacecraft, then using the delay-free nature of quantum entanglement, whatever the eye sees will be synchronized to the spacecraft at the same point in time, and we will have a way to understand the world around us in real time, and even extend the distance to 100 astronomical units, 1 light year. ”

"There are quite a few researchers in the research department who feel that this path should be taken, though. This road seems to be bright, but there are still many problems, the most important thing is, how to keep a pair of eyes, or even more probes that act as our eyes, in sync with the spacecraft? ”

"This problem, the research department has been groping for 10 years and has not made progress, or the cost is terrible, which will make the cost of a Changyang-class rise to 6 billion merits. A 200-fold increase is completely unacceptable. ”

"The third solution..."Cao Chuan shared his own exploration and conclusions summarized through the rule simulation. In this way, he will publish the design drawings of the deep space radar below, and the mental model girls will know how to do it.

"This path is the most popular dark energy observation in the last half century, just like the spatial folding brought about by the dark energy tide, making the space shorter, if the light is affected by the dark energy tide. The speed of transmission will increase, and information that would have taken one year to see may take up to half a year to receive. ”

However, the third idea, which is also difficult to solve, is based on the use of light or electromagnetic waves as a medium of observation. There must be a dark energy tidal wave, assuming that the spatial folding rate is extremely small, just let us see that the world 100 years ago is compressed to 50 years, and the effect is not good. ”

"The above are the directions that the research department has worked towards, and I have to say that all three have failed, which is normal, there are many paths through the truth, and not all of them can be taken."

Cao Chuan finished slowly: "Now I'm going to announce the real answer." ”

The 3 loli waited with reverent eyes for the owner to reveal the answer.

"After one year of regular simulation, the real principle of deep space observation should take the high-dimensional observation method, using the same superluminal speed propagation of dark energy as the observation medium to obtain a high-dimensional world picture, and then convert it into a three-dimensional world picture through mathematical formulas, which is what we want."

Nana asked, "Does it sound similar to the third option?" ”

"Indeed, the biggest difference is in the medium of observation, we no longer use light as the medium of observation, and choose dark energy, the superluminal propagation characteristics of dark energy, and even the extradimensional propagation characteristics, resulting in it transmitting information faster than light."

"I think I know what I'm going to do." Nana pondered, "Suppose we dismantle the development of deep space radar, first of all, to understand dark energy? ”

"That's right..."Cao Chuan nodded, "We don't know enough about dark energy, we regard it as an elementary particle, but there is no data on its physical properties, the only thing that can be inferred is that its propagation speed starts from the speed of light, and the upper limit is not known yet." ”

"So... What kind of experiments do we need to design to understand? Even light, on which humans rely the most, is useless in the face of such tachyon particles..."The three loli discussed with each other.

"According to the theory of relativity, in this case, time and space will be distorted, and even if we find an experimental method, we will not necessarily come to a conclusion in the real world." Nana continued to throw questions.

The wisdom of the mental model allowed them to grasp the key to understanding dark energy at once.

Of course, Cao Chuan stumbled on this problem, the rule simulation stumbled for a long time, otherwise he would not necessarily have been in the past time, and completely let the rule simulation hang up, is this possible?

Obviously not, so he already had the answer in his mind. Now, in order to facilitate the participation of 3 Loli in the development process of deep space radar, a guided approach has been adopted to increase the learning effect.

Cao Chuan began to describe the process of the experiment in detail, this experiment called "space penetration" is an upgrade in the dark energy observation experiment, which can be described as a milestone level in the field of basic science, allowing human beings to jump from seeing dark energy to touching dark energy.

In fact, many people can't understand the specific details at all, and they can only understand it from the theoretical knowledge involved.

For example, Hilbert space is used to explain the fundamental laws of operation in high-dimensional spaces.

For example, there is a lack of information from light to refer to, and the experiment adopts a control method to understand the difference between different variables and the experimental results.

For example, in order to counteract the space-time distortion that may be caused by the speed of light, special constants are introduced to facilitate subsequent calculations.

…

If it weren't for the fact that the rule simulation had been carried out many times, Cao Chuan's various hypothetical inferences would have been very likely to be flawed. But now, why not move forward if the rules simulation gives fairly credible results?

With the cooperation of 3 Lori, coupled with Cao Chuan, the work efficiency can be increased by 1000%, they directly found a vast starry sky, and seized the time to complete the calculation in the last few months, obtaining more accurate data on the nature of dark energy, paving the way for the design and implementation of deep space radar behind.
