Chapter 657: Cosmic Starry Sky

At that time, people also began to become curious about the starry sky, and various conjectures were born. Due to insufficient in-depth understanding, many ideas also had absurd errors, such as the theory that the sky is round and the earth is round, and that the earth in Europe is the center of the solar system.

The false statement that the sun revolves around the earth.

With the progress of society and the continuous development of science and technology, those wrong conjectures have begun to be overturned.

The ancients never thought that people could fly in the sky, but airplanes appeared. In the age of steam, the industrial revolution, and the age of electricity, cars appeared one after another. The iron shells could run faster than horses. Aircrafts even achieved supersonic speeds.

Flying is twice or even three times the speed of sound. In ancient times, it would take several months to walk or ride a horse to Beijing to take the exam. Nowadays, it may only take three to five hours to reach the same destination at the same place, saving dozens of hours.

Hundreds of times.

Entering the 20th century, and even the 21st century, with the launch of manned spacecraft, humans are no longer limited to flying in the sky, but have broken through the atmosphere, entered outer space, orbited the earth, and even landed on the moon.

Science and technology are constantly developing, and human beings are constantly making progress. In one hundred, one thousand, five thousand years, who knows in that distant future, it may not be impossible for humans on earth to break through the constraints of the solar system and enter the wider starry sky of the Milky Way.

.

The starry sky is bright and vast. The diameter of the Milky Way alone is 100,000 light-years, and the speed of light is 300,000 kilometers per second. At the speed of light, it would take 100,000 years, which shows how vast it is. As for the Milky Way,

outside

In the universe, the boundless starry sky, planets, stars, comets, neutron stars, white dwarfs, hundreds of millions, billions, tens of billions, or even hundreds of billions of planets, Ye Xing does not believe that only the earth is the life.

planet.

Among these billions of planets, there is no way that only one planet like Earth is suitable for life. There must be other planets with life in other exotic stars in the universe, and they may or may not be inhabited by humans.

, are other extreme life forms.

The earth is not the center of the universe, and the universe does not revolve around the earth. The earth is just a planet in the solar system, and it revolves around the sun.

In fact, after the Big Bang, the early Earth was also a dead star. Later, as the starry sky environment changed, planets, comets, meteors collided, and the crust moved, they merged together again, with more water and oxygen, and life forms were born.

, that is, dinosaurs, Tyrannosaurus rex, saber-toothed dinosaurs and other large carnivores.

But later on, the dinosaurs became extinct, and the earth gave birth to brand new life forms, single-cell evolution and various other evolutions. Human beings are advanced animals evolved from apes.

In the primitive period, human beings had low productivity and lived a life of eating hair and drinking blood. At that time, many human beings could only live for ten or twenty years. Until entering feudal society, life span was extended a lot, but it was only forty or fifty years old. The ancients

When you are thirty, you call yourself an old man, but when you are fifty, you know your destiny.

People who lived to the age of fifty were considered longevity in ancient times, so the custom of birthday celebrations was born. This custom has been passed down to this day. When modern people reach the age of fifty, they also have relatives and friends send gifts.

Happy birthday, may you be blessed with longevity in the East China Sea, Nanshan Mountain, etc.

Of course, with the improvement of medical standards, modern people generally live to be in their seventh or eighth decade, and some even live to be over a hundred years old.

In terms of medical treatment, biology, etc., human research is getting deeper and deeper. It is possible to clone an identical person or animal from a cell or even a hair. This was an incredible thing in ancient times. As for the future

To what extent science will develop, God knows.

Of course, in addition to these inferences, there is another important reason why Ye Xing believes in aliens. That is that he himself has left the earth. He should be regarded as the first person to leave and reach the Wulin Continent in another world.

Wulin Continent is a world of martial arts, which is completely opposite to that of the earth. Martial arts pursues its own breakthrough from the inside out, cultivating individual energy to the extreme; while the earth follows a technological route, with more technological routes.

The purpose is to rely on external forces, such as pistols, tanks, fighter jets and other mecha-like foreign objects.

Improve yourself. For example, compared with those who hold pistols and the acquired warriors, it is not necessarily true that one can kill the other. It is possible that the earthling holding the pistol was killed by the acquired warrior before he had a chance to shoot, or it is possible that the acquired warrior

The warriors in this realm were defeated by the pistols of the Earthlings. It depends on the tactics and environment, each has its own advantages and disadvantages.

In short, martial arts civilization and technological civilization each have their own characteristics, and they can be regarded as two unique civilizations. Maybe there are more than these two civilizations in the vast starry sky, who knows.

Regarding the spatial location of Wulin Continent, although Ye Xing has a purple light group portal, it is still unknown. It may be in some distant unknown star field, or it may not be in this starry sky at all.

Ye Xing is currently most worried about the issue of aliens. From Aunt Xu's photo and various inferences, it can be judged that alien flying saucers have indeed visited the earth. However, they seemed to have left later for unknown reasons, but since they came once,

Who knows that he won't come again next time, after all, the other party has already discovered the coordinates of the earth's starry sky.

"Instructor Ye, if aliens really invade the earth, will you...will you help?" Aunt Xu suddenly asked.

"Definitely!" Ye Xing nodded, and then smiled bitterly: "It just depends on whether I have the ability to help!"

The earth is Ye Xing's hometown, this beautiful aqua blue planet. Ye Xing naturally can't bear it to be destroyed by war. If there is really an alien invasion, Ye Xing will definitely help. But this kind of thing can only

It can be said that we should act within our ability, after all, we know too little about aliens. Who knows what terrible black technology those mysterious aliens have.

"Instructor Ye, you are too modest." The short-haired girl Feng Qi said: "You were so perverted last time in Japan. Even the missiles couldn't hurt you. You are a superhuman existence. I guess aliens can also attack you."

But you!"

"This is different. A missile is a missile, not the most powerful weapon." Ye Xing rolled his eyes and said, "If I am hit by a nuclear bomb, I will die too, okay?"

"Hehe, it turns out that there are things in this world that you are afraid of!" Feng Qi, a short-haired girl, smiled, rolled her eyes, and couldn't help but said curiously: "Instructor Ye, you said that if there are aliens, what will those aliens do?

What does it look like?”

"How do I know? It could be red skin!" Ye Xing murmured, "It could also be green skin. He was born green."

"Puch, you really dare to think about how ugly it would be if you had green skin!"

"Hey, you really don't believe it. There are three types of people with three skin colors on the earth. Due to the influence of climate environment and other factors, Africa is basically black, Asia is yellow, and Europe and the United States are mostly white.

.How do you know that aliens are not green people? Maybe the environment of other alien planets is more special."

Ye Xing was also aroused by this little girl. "Think about it, we humans on earth evolved from apes, so aliens may also evolve from tigers, or even elephants."

He came here with such a long nose..."

(Yes, the author is preparing to break through the atmosphere and take everyone to travel in the starry sky of the universe. Black holes, white holes, auroras, singularities, nebulae and other wonders of the universe will usher in the interstellar era in the near future. Hum, our
