Du Fei took out the Void Armor fragment and rubbed it carefully, while carefully recalling the detour of the battle with the Shadow Demon Zeratul, everything was normal, until the moment he used the Hitomi Jutsu Yue to read... ・・

I only felt a huge amount of energy smash my head, and as soon as my eyes went dark, there was a momentary blank in my memory, and after I woke up, the shadow demon Zeratul evaporated from the world.

There is also a black energy on the Shadow Demon's body that is also very strange, very similar to the energy chain transplanted on the Blood Siren, but the nature is very different, the black energy has a strong penetrating ability, and the destructive ability is reduced. In other words, the blood-colored energy chain directly destroys the shield, while the black energy passes through the shield and attacks the person behind the shield.

Du Fei checked a lot of information, trying to figure out what kind of substance this black energy and Void Saint Armor was.

The homogeneity of the energy chain and source force transplanted by the Tyrannosaurus Rex and several people has reached |, but I don't know if this black energy will be homogeneous with the source force.

I just rummaged through the information I could find, and I didn't have a clue.

In the end, Lin Zhen suggested that Du Fei find an astrophysicist, and Du Fei thought that aliens were somewhat related to astronomy, and energy matter was inseparable from physics.

The astrophysicist introduced by Lin Zhen is still a celebrity, named Ye Tianhua, an old man in his seventies, who used to be the director of the Modu Observatory.

Sitting in Ye Tianhua's residence, Du Fei glanced at the furnishings of the room, all of which were planet models and galaxy photos.

Du Fei saw that the old man was very easy-going, and he was not polite, so he went straight to the point and asked; "Chief Ye, do you think the monsters that appear on Earth are really alien creatures?"

Since human beings have not really observed the passage of alien creatures landing on the earth, and have not found UFOs and other flying machines, the invasion of alien creatures is just a thing that everyone believes, in fact, there is no direct evidence that Pandora's creatures are from outer space o and the matter of Protos and the shadow demon Zeratu is only known to Du Fei himself, so he has this question.

"Human beings know too little about the universe, and all cognition depends on the eyes to observe. According to the current scientific and technological understanding of human beings, it will be very difficult for biological races to invade other planets through travel. Ye Tianhua did not answer positively, but the meaning of his words had already expressed his opinion.

"Then what do you think if the monster that appears on Earth is from Kepler's 22ˉB star leaf director?" Du Fei threw out another important piece of information.

Kepler-22B was not fabricated by Du Fei, but a planet suitable for human habitation discovered by country M, and more importantly, the name of Kepler-22B came out of Zeratu's mouth.

Of course, if you communicate in the original language of Zeratul, the planet is definitely not called Kepler-22B, and Zeratul found this term from human knowledge. Since Zeratul's original method of communication was spiritual communication, there was no transliteration or the like, and only the original human nouns could be used.

Ye Tianhua took a sip of the coffee brought by Du Fei and sighed; "It's been a long time since I've tasted like this, thank you, boy. However, the Kepler 22 ̉B you are talking about is so many light years from Earth that even if you travel at the speed of light, it will not be until the 27th century. ”

"Isn't there a being that exceeds the speed of light?" Du Fei asked.

"Perhaps one year ago, the European Center for Nuclear Experiments (EERN) showed that neutrinos can travel faster than the speed of light, which directly overturned Einstein's view. However, this result has not been confirmed by most scientists. Ye Tianhua said.

Human beings have always believed that the speed of light is the ultimate speed of the universe, and Du Fei did not expect that the speed of light would really exist, but this is not the focus of today's inquiry, but he asked; "Is there any matter and energy in the universe that has not been discovered by humans?"

"This is naturally the case with astrophysics that collectively refers to these substances and energies that cannot be observed through electromagnetic radiation as dark matter and dark energy. It is also unknown to humans because they cannot observe this part of the darkness. And how many kinds of dark energy are there, and what are the specific components. Ye Tianhua talked about his profession, and began to explain endlessly.

Du Fei listened quietly.

"According to the Big Bang theory, the expansion of the universe should be at a constant speed, or under the influence of gravity, it should be decelerate. But the scientific community has long confirmed that the universe is still expanding at an accelerated rate. This shows that there is an invisible energy in the universe that is accelerating the expansion of the universe. ”,

"After calculation, the cosmic matter visible to human beings only accounts for ● of the universe, and the dark matter is 2%, and the rest is the dark energy that causes the accelerated expansion of the universe." Ye Tianhua continued to explain.

"Why can't dark matter be observed?" Du Fei asked. Ye Tianhua mentioned dark matter and dark energy, and Du Fei was in his heart, maybe the body of the Shadow Demon Zeratu was made of an unknown dark energy or dark matter.

"Because dark matter does not emit electromagnetic waves, and does not react with electromagnetic waves. Light is a kind of electromagnetic wave, which cannot be seen by humans, and needs to be received by machines, and naturally there are things that cannot be observed by machines. Ye Tianhua explained carefully, now that there is no astronomical observation equipment, he is also willing to have someone to chat with him.

"Then Mr. Ye, do you think it is possible that there are energy creatures?" Du Fei asked again.

"Young man, do you know anything about string theory? If this theory is correct, matter is made of energy. Isn't it amazing that the vibration of the string forms the particles, and the particles build up all kinds of matter? Humans have been searching for the secrets of the microscopic world, but they have been constrained by particle acceleration technology. Ye Tianhua said.

Du Fei was shocked, he only stayed at the stage of hearing about string theory, if it is really as Ye Tianhua said, matter is a manifestation of energy, then what is the difference between the so-called energy creatures and creatures?

"According to string theory, do wormholes really exist?" Du Fei felt that his brain was really a little insufficient.

"In the past, I was skeptical of string theory, but now in the world, there are people who can travel through extra dimensions and move in space. It seems that string theory is not just philosophy. Ye Tianhua sighed.

"Extra dimension?" Du Fei asked suspiciously.

"According to different string theories, the universe has many dimensional spaces. The current M theory holds that the universe has a ||dimensional space, and human beings live in the third dimension. Ye Tianhua explained.

"I don't understand, what's the difference between 4D and 3D?" Du Fei asked, because he was not a physics major, he knew very little about these cutting-edge knowledge.

"Young man, if you want to understand Einstein, you have to jump out of Newton, and if you want to understand string theory, you have to jump out of Einstein. In the two-dimensional world, that is, the flat world, you can only find 2 straight lines that intersect perpendicularly, in the 3D world you can find 3 straight lines that intersect vertically, and in the 4D world, you may be able to find 4 straight lines that intersect vertically. Ye Tianhua explained.

"In this way, by traveling through the dimensional dimension, it is possible to travel through time and space. It may only take a blink of an eye to get from Earth to Kepler 22B? Du Fei guessed.

"Maybe・・・・・・"

PS; Knowledge about dark matter, dark energy, faster than light, string theory, etc., is not made up by the author, these are the frontiers of physics.

I have been thinking about this chapter for a long time, whether to write it or not, because it is estimated that many book lovers have never heard of this knowledge, and it is like a book from heaven when it is written, and it is suspected of irrigation. However, in order to make energy creatures and alien technology seem more reasonable, I decided to write it.

This knowledge is written after the author understands it, and it cannot be guaranteed to be correct・If you are interested, you can Baidu ・・・・・・

"The Big Bang Theory" has the popular science content of string theory・・・・・・ (to be continued.)
