"As for Tianyantong, I haven't cultivated it yet, and the body of this world doesn't seem to have this kind of talent, you were born with Tianyan, and you may know a little better than me. Pen & Fun & Pavilion www.biquge.info With my understanding of the meaning of the scriptures, if Tianyantong is explained in popular language, it should be able to see the electromagnetic waves of each spectrum and frequency band, while the normal human eye can only see the visible light part, I don't know if my understanding is wrong? Ning Zhi didn't hold the shelf, and when he said Tianyantong, he actually asked Luoyang's opinion.

Luoyang shook his head, "You can only see below the infrared frequency band, and the high-frequency may be visible, but the frequency is too high for the optic nerve to distinguish, which is equivalent to being invisible, such as ultraviolet rays, X-rays, and gamma rays." ”

When the frequency of electromagnetic waves is too high, there will be a 'stationary effect', such as the first time Luoyang saw a mobile phone emitting a short-wave signal, it had the illusion that it did not exist.

With the improvement of cultivation, the speed of nerve reaction has increased, and Luoyang can now recognize microwaves, but if the frequency is increased a little more, there is nothing that can be done.

For example, ultraviolet rays have a wavelength of only a few tenths of a micron, so how sharp are the nerves to be able to distinguish them? As for X-rays and gamma rays, the wavelength is measured in nanometers and angmi.

"Theoretically, it can be seen, it is true that your nerve reaction speed is not enough, and after your spiritual cultivation is improved, the scope of Tianyan's ability should be expanded." Ning Zhi said.

"There are still some omissions in what you just said." Luoyang added.

Ning was a little surprised, "What did I miss?" ”

"I can also see a strange wave that swirls around the star."

"What's that?" Ning Zhi looked dazed.

Luoyang was even more dazed, he originally wanted to get a useful answer from Ning Zhi here, but he didn't expect that he didn't know anything.

"I don't know, it's not an electromagnetic wave anyway, this kind of wave doesn't travel in a straight line, I guess it might be a gravitational wave." Luoyang thought for a moment and explained to Ning Zhi a little.

"Gravitational waves?" Ning Zhi was surprised.

Luoyang almost knows the level of physics that Ning is waiting for, and he is also at the level of a high school student, and he understands simple concepts such as sound waves and light waves, but he must have never heard of gravitational waves, so he popularized science with him, "Gravitational waves refer to ripples in the bending of space-time, which propagate outward from the radiation source in the form of waves, and this wave transmits energy in the form of gravitational radiation." In 1916, Albert Einstein predicted the existence of gravitational waves based on the general theory of relativity, but gravitational waves have not yet been detected. ”

"No need for popular science, I've heard of it, it's been very popular on the Internet recently." Ning Zhi interrupted Luoyang's words.

"It's been hot on the Internet lately?" Luoyang is confused, gravitational waves are quite an unpopular concept.

Because it has not been detected, many scientists have doubted its existence and have begun to revive the theory that gravity is acting at a distance.

"Come here." Ning wanted to say something, but felt that his professional level might not be clear, so he went to the study and restarted the computer and router, and it took two or three minutes for Baidu to search for a web page and let Luoyang go over to see it.

Luoyang walked over suspiciously, looked down, and was immediately attracted by the headlines of the website.

"LIGO discovers gravitational waves again, experts say it is possible to win the Nobel Prize"

In the early morning of June 16, Gyeonggi time, scientists from the American Astronomical Society's LIGO Scientific Collaboration (LSC) and Virgo Collaboration held a press conference to report that they had once again detected a gravitational wave signal. The signal shows that two black holes with masses of about 14 and 8 solar masses have merged to form a black hole with a mass of about 21 solar masses, showing that matter with about 1 solar mass is released in the form of gravitational waves. This merger of the two black holes took place 1.4 billion light-years away......

"Yesterday's news ......" halfway through the news text, Luoyang was already stunned, muttering to himself.

As a fairly professional physicist, he knows what it means for gravitational waves to be discovered.

It is equivalent to opening the eyes of heaven to physicists all over the world, enabling them to see many things that were once invisible, and opening the door to a new world.

Some undecided theories can also be applied boldly with confidence.

As the summary comment at the end of the news: it is foreseeable that gravitational waves will open an unprecedented great era, and if the last discovery is doubtful, the discovery again has largely eliminated everyone's doubts, and also made us more convinced and aware that as long as the equipment is sensitive enough, we can detect the sound from the sea of stars on a regular basis and see the imperceptible side of the universe.

"Again?" When Luoyang saw this, he couldn't help but be stunned again, and then he searched it on Baidu and figured out what this 'again' meant.

It turns out that this is not the first time that human scientists have discovered gravitational waves, the first time was in February this year, but the data of that discovery was not accurate enough, and the impact and reliability were not as good as this time.

He had just escaped from the Roselle project base in February, fleeing like a headless fly all over the world, presumably because of this reason, he missed the big news that shook the physics community.

Now that the gravitational waves have been confirmed, the unsolved doubts in Luoyang's mind have been solved, and the swirling waves around the star should be gravitational waves.

"Are these gravitational waves you see?" After Luoyang finished reading the news, Ning waited before asking.

"It should be." Luo Yang nodded.

"Can you harness these gravitational waves in the same way you use electromagnetic waves?" Ning asked asked.

Luo Yang shook his head and said with a wry smile: "Gravitational waves have just been discovered, and the applied physics is still a blank, and I don't know how to use this power, but I can enjoy famous paintings anytime and anywhere, or IMAX, and it's also quite enjoyable." ”

"What famous painting?" Rather let Luoyang be a little confused.

"Van Gogh's Starry Night." Luoyang Road.

Ning waited for a moment to be silent, and after a long while, he spoke: "You may be looking at the world from the perspective of a Buddha. ”

Luoyang heard that he wanted to bring the topic to the side of idealism again, so he hurriedly stopped: "Let's talk about the remaining three supernatural powers, or great supernatural powers, it should be very powerful." ”

"He has a clear mind: he can know what is in the minds of sentient beings in the six realms." I'd rather start with theory.

"This shouldn't be difficult, right?" Luoyang interjected, according to his understanding, his heart communication should even be simpler than Tianyantong, at least theoretically.

If you think of the human brain as a computer, the human mind is the computer's video memory data, and the memory is the hard disk data, and it should not be difficult for a slightly clever hacker to steal it.

But in fact, this is not the case, Bai Haichan told him that people's thinking and memory cannot be stolen, and consciousness cannot be controlled by external forces, but can only affect the nervous system, modify the output and input instructions, and make people hallucinate, or their behavior is controlled.

And his heart is listed as a great supernatural power, and it is enough to see that this matter is not as simple as he thought.

Therefore, Luoyang used interrogative sentences, rather than blind conclusions.

Ning Bei shook his head, "It's very difficult, the human mind is the most complex thing in the world, and even the wisdom of the Buddha can't be discerned. ”

"Why?" Luoyang didn't quite understand.

"I heard that you are a doctor of biology, I wonder if you have studied the structure of the human brain?" Ning asked rhetorically.

Luo Yang nodded, and then shook his head: "My main direction is genetic engineering, and I have not studied the human brain in depth, so my understanding is relatively limited." ”

"I'm interested in that, but I've done some research." Ning Zhi said, this time it is his turn to popularize science with Luoyang, but the theory of popular science is quite simple, Luoyang basically knows everything, presumably his research in this area is also very limited, not in-depth, belongs to the level of half-tone, but some of his own views, but let Luoyang's eyes shine, feel that Ning Zhi is a very imaginative civil science, "There are nearly 100 billion neuronal cells in the human brain, and each neuronal cell has a different number of synapses, as few as dozens, as many as thousands, these synapses are connected to each other, A neuronal network of information exchange and processing is formed. ”

"I know all these basic things." Luoyang said.

Ning Zhi was not interrupted, and continued: "Presynaptic cells use chemical signals to relay information to postsynaptic cells, called chemical synapses, and those who transmit information with the help of electrical signals are called electrical synapses. Almost all of the synapses that are transmitted in mammals are chemical synapses, which is the mainstream view in biology today. ”

"Any questions?" Luoyang asked.

"There is a big flaw in this theory, I have told you how complex the brain's neuronal network is, there are trillions of synaptic connections, assuming that each synapse is only one micron, then the length of the entire neuronal network is more than 3 million kilometers, even if it is an electrical signal transmission, it takes about ten seconds to run a circle in the brain, and if it is a chemical signal transmission, it even takes several years."

"Wait, neuronal synapses are parallel, not tandem, and you can't count them as you do." Luoyang pointed out the mistake of Ningzhi.

"Didn't I give you an example, so that you can understand, of course you can't count it according to me, but think about a question, does information only need to be passed once in each neuronal cell? Factoring in this, my answer is actually not much different. ”

Luoyang nodded, thinking about a problem in his brain, information should be transmitted between synapses millions of times, and then take its weight, which does not take into account the problem of information traffic jams.

"If the synapses are transmitted by chemical signals or electrical signals, this will happen, and we will all be in a vegetative state."

Luoyang was speechless for a while, and there is indeed a problem with the current theory of neuronal information transmission.

"So I think the human mind doesn't actually exist in the real world, but in another world." Ning waited to speak, and the conversation suddenly changed, and he changed from a civil science to a god stick again.

"It's not...... What do you mean? Luoyang was not adapted to this change for a while.

"I mean to say that human consciousness is not generated by the brain, but is determined by the soul, and the soul does not exist in the real world, so it cannot be observed."

"What world, Hades?" Luoyang was a little crying and laughing.

"The Buddha divides the world into the world of desire, the world of color, and the world of colorlessness, collectively known as the three worlds, the world of desire is the realm of beings who have not got rid of the worldly seven emotions and six desires, that is, the real world and the material world, and the world of color is the world that has got rid of appearances and materials, and is a pure spiritual world, which is inhabited by the detached, without birth, old age, sickness and death, resentment, love and separation, and inability to ask for it.

Ning Zhi then said a lot of things that made Luoyang's brain hurt.
