Du Fei took out the Void Armor fragment and rubbed it carefully, while carefully recalling the process of fighting with the Shadow Demon Zeratu over and over again, everything was normal, until the moment when 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 reached 15%, but I don't know if this black energy will also 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 the sky, 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.

Seeing that the old man was very easy-going and not polite, Du Fei cut straight to the point and asked, "Director Ye, do you think the monsters that appear on the earth are really alien creatures?" ”

Since human beings have not really observed the passage of alien creatures landing on the earth, nor have they discovered UFOs and other aircraft, the invasion of alien creatures is just a thing that everyone believes, and there is no direct evidence that Pandora's creatures come from outer space. Moreover, the matter of Protos and the shadow demon Zeratu is only known to Du Fei himself, so he asked.

"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 if the monster that appears on Earth comes from Kepler-22-b, what does Director Ye think?" Du Fei threw out another important piece of information.

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

Of course, if you communicate in Zeratul's original language, the planet is certainly not called Kepler-22-b, 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: "I haven't tasted this taste for a long time, thank you, young man." However, Kepler-22-b is more than 600 light-years away from Earth, and 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, 11 years ago, the European Center for Nuclear Experiments (ECERN) showed that neutrinos can travel faster than the speed of light, which directly overturned Einstein's view. However, it was later proved that it was the optical cable interface problem that caused the error in the experiment. Perhaps, surpassing the speed of light is really just a joke......" Ye Tianhua said, and also sighed, perhaps regretting that he could not see a new breakthrough in physics in his lifetime.

Human beings have always believed that the speed of light is the ultimate speed of the universe, and due to the existence of the mass-energy equation, the speed of light is even regarded as a cosmic constant, which belongs to a law, a law connecting mass and energy.

However, this is not the focus of today's inquiry, Du Fei instead asked: "Is there any matter and energy in the universe that human beings have not discovered?" ”

"This nature exists, and in physics, these substances and energies that cannot be observed through electromagnetic radiation are collectively referred to as dark matter and dark energy. Since humans cannot observe it, it is not known how many kinds of dark matter and dark energy there are in this part, nor what the specific components are. 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 driving the expansion of the universe at an accelerated pace. ”

"After calculation, only 4% of the universe matter visible to human beings is the universe, 23% of the dark matter, and the remaining 73% 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 creature and ** creature?

"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 11 dimensions of space, and that humans 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......"
