The ocean is the same, the water and the sky are the same.

If it weren't for the tireless embrace and fragmentation of the white waves on the sea, it would be really difficult to distinguish between heaven and earth.

A flat boat, as small as a star.

The lone boatman, his eyes glazed over, stared in one direction, as if he had been in this position for centuries.

Time has lost its meaning to him, like time before the birth of the universe.

He felt that 50 billion light-years away was a cosmic sea. The universe he is in spans more than 400 light years, but it is just an ordinary blister in that cosmic sea.

Originally, this universe was just an accidental chance in the abyss, and it obtained a different state from the cosmic sea. If the cosmic sea is like a liquid, then the universe in which it is located has become a gas.

So, at this moment, the universe gained buoyancy and began to rise.

The higher it rises, the less homogeneous the cosmic sea is subjected to, so the universe begins to inflate.

Originally, all the matter in the universe was like neighbors living in a courtyard, visiting each other and being intimate, however, the inflation came, and the courtyard became a community, and the community became a small town, and the town became a city, and the city became a metropolis.

There should be four basic forces in the universe that everyone is familiar with: electromagnetism, strong interactions, weak interactions, and gravity.

However, in the courtyard era of the universe, in addition to gravity, the three forces are one, just like a pair of neighbors, one has a bicycle and the other has a car, because the distance is too close, there is no essential difference in the speed at which they go to each other's houses.

With the expansion of the universe, the era of good-neighborliness and friendship in the courtyard came to an end, and the era of the community came to the beginning, and the first thing to differentiate was the weak force with the shortest operating distance.

Why does a weak force act at the shortest distance? It turns out that the weakly interacting neighbors maintain their relationship by passing gifts to each other, and their gifts are so valuable that they reach 100 times the mass of protons.

These gifts are the +, - and z bosons, which represent eak, the weak of the weak force, one with a positive charge, one with a negative charge, and one without an charge, so it is called zero.

Can you imagine that two families who interact with each other often exchange gifts for 100 times their body weight? It's too much work. In the days of the community, they couldn't come and go.

The strong interaction between the neighbors lasts longer, because the gift they exchange is glue, which has zero mass and can be spread far away, but the gift of glue is so good that it can make the neighborhood so good that it forms quark confinement.

In fact, the binding force of confinement is so strong that it occupies most of the mass energy of protons or neutrons, and the more subdivided quarks themselves account for only 1% of the mass energy.

Here's another example to illustrate the power of quark confinement energy: the nucleon force we are familiar with binds protons or neutrons to form atomic nuclei. With nuclear weapons, we have already appreciated the power of this nuclear force, but the nuclear force is only the force formed by the occasional drop of glue between the fingers of the quark confinement binding force.

Just like this pair of glue-like neighbors, they give each other a big bag of diamonds every day, and the occasional drop of a broken diamond will make the passers-by who pick it up ecstatic, and have a very considerable social capital.

The nuclear force is the force formed by leaking and remaining gluons, and the range of action is the size of the nucleus.

The cosmic bubble continues to inflate, the community era is a thing of the past, and now it is the small town era. In this era, only good neighbors who exchange photons have a chance to stand out.

Photon gifts don't make their neighbors too strong, they have zero mass, and they can enjoy the endless benefits of the Big Bang and travel the ever-expanding universe at the extreme speed of the universe.

The photon flew over the town, over the city, over the metropolis, and became the most successful gift in the history of the universe.

The photon of fraternity, in addition to bringing feelings to the nearby residents, will also fly into any people's homes like a drifting bottle in the universe.

The greatest love of photons is when they encounter a rocky planet, and it just so happens that the surface of this rocky planet is also full of water, and the birthplace of photons, stars, if the distance from the planet is exactly at a proper distance, an endless stream of photons will control the water on this planet in a liquid state.

The extremely abundant chemicals on rocky planets are undergoing extraordinary drastic changes in the perfect reaction vessel of liquid water, and the process of evolution has already begun in this era of inorganic domination.

Drastic change means intense competition, and only the most stable chemicals can achieve a numerical advantage. And among the most stable substances, there is a strange thing that can use the energy brought by photons to reproduce itself unscrupulously, which is the mother of billions of living beings.

What about gravitational force, which is very different from weak, strong, and electromagnetic forces? Or return to the imagery of the cosmic sea.

Our entire cosmic bubble rises in the cosmic sea, so all living beings can't feel their own motion, but they can feel a gravitational pull everywhere, which is gravity.

Gravitational attraction is equivalent to our universe moving in a certain direction. Just like balls of different sizes tumbling down a slope, in the end, balls of similar size will cluster together because of the similar resistance they are subjected to.

The properties of matter with mass in the universe and matter without mass fit this analogy, and matter with mass appears to be gradually coming together because of the same resistance.

Scientists may never be able to unify the models of gravity and the other three forces, because they are not the same thing at all. Scientists may never be able to discover the so-called graviton, because gravity does not exist.

It is the relative motion of the whole universe, and the direction of gravitational attraction that we see is a projection of the difference in velocity between matter and vacuum in the fourth dimension of space.

Born from the heart, the boatman lies on his flat boat, looking up, the four seas are vast, he doesn't know if what he sees is the real sea, or the cosmic sea, or neither, just a dream, an enchantment?

The thought of "dream" flashed through him, and he quickly moved on to another image.

This time, 530 million years ago, the earth was even more of an ocean, counting the days, now it is the Cambrian period, and there will be a major explosion of biological species.

The factual evidence of the Cambrian explosion also puzzled Darwin, who proposed the theory of evolution, and wrote in On the Origin of Species: "This matter has not yet been explained." So, maybe some people can just use this case to refute my evolutionary argument."

What is going on to make the species explode at this juncture?

The boater dreamed of a clear blue sky with enough oxygen to produce an ozone layer that shields large amounts of ultraviolet light, which can easily break the DNA chain and make it difficult for complex multicellular organisms to form.

In about 530 million years, it took 20 million years to evolve almost all animal phyla.

Maybe there's something else. The temperature of the earth was dropping, and finally, the dreamer saw that the murky waters were beginning to become clear. Photoreceptors are in use.

The eyes are a super-important organ, and increasingly sophisticated, powerful predators appear, and in order to escape or hunt, chordates appear. Those who can't run fast should be thickened with armor, and crustaceans appear.

Everything is free under the sea, it is really a beautiful dream.

The competition is brutal, yet the most efficient. Why did advanced ancient civilizations appear in Eurasia instead of the Americas or Africa? Because Eurasia is the largest, not only large, but also east-west, at the same latitude, the way of life can be spread at the fastest speed, and the dominant way of life will quickly reach the entire continent.

Africa, on the other hand, is separated by a large desert, with a narrow north-south lifestyle, each with its own climatic zone.

North and South America together are large, but they are also north-south, and the east and west are also blocked by the Andes Mountains. It is difficult for agricultural techniques to cross different climatic zones.

As a result, 10,000 years ago, after the melting of the glaciers, agriculture in Eurasia developed rapidly, while agricultural civilizations in Africa and the Americas struggled.

What about the world after entering the industrial civilization? How did European civilization come to the fore?

It is also because the competitive environment is very different, the great unified civilization of the East is stuck with the arrogance of the dragon, but the fragmented European feudal lords bloom in the cruel competition, and the magnificent Age of Exploration begins in order to pursue profit.

For the manufacture of the nautical clock, the British monarch issued a large bounty to his subjects. For the sake of colonization, the Europeans constantly improved firearms. They also invented the legal system and used the law to protect intellectual property. The power of patent law led to the improvement of the steam engine......

The dreamer sees the vitality of iron and blood brought about by free competition.

But, in the end, what will happen when the brutal competition of the entire human race ends with the strong intervention of the tyrants?

The dreamer thinks he will never have a chance to know, because ...... He was dying. He sensed the coming of death, and perhaps his current dream was just a return to light.

But, no, I seem to be waking up.

"I ...... Who am I? The dreamer whispered.

Someone actually replied to him: "You used to be a person, but you are not now, congratulations, you have become a member of the undead." ”

The dreamer frowned, as if he had just woken up and felt a little dizzy, and he saw a dignified fairy dancing in the sky on the surface of the endless sea.

"You...... Who is it? "Dreamers have a lot of questions.

Fairy: "I'm your nurseryman, Charlotte. ”

Dreamer: "What the hell is a childcare worker?" ”

Xia Luo: "The young of birds and beasts are born with a strong ability to survive, and the human head is getting bigger and bigger, and if it is fully developed and then gives birth, it will not be born at all, so the human childhood is extremely long.

Fortunately, it's all a thing of the past. Now, we humans have evolved to the age of the undead, back to the oviparous age, and everyone is born from a giant egg, not only with a mature brain, but also with a lot of memories.

Do you think you're mature? Actually, you are a baby, you will be born in half an hour, and as soon as you are born, you will be an adult. Welcome to this brave new world. ”
