Overview
Over the years, mankind has often been complacent about its own birth, and even in the long course of history once considered itself as the master of the world. However, when we look into the night sky and discover the infinite universe hidden behind it, we realize that the existence of human beings is just a "mayfly shaking a big tree, ridiculous not to measure themselves" compared to the universe.
The earth is like a tiny cell in the universe, and we are born and grow inside this small cell, and over time we begin to think about our meaning to the universe.
Would the universe have any meaning if there had never been a human being? Obviously yes, the universe did not appear and exist because of humans, humans are just a small accident in the development process of the universe, if the universe is really a conscious life form, it may not have actively intended to make humans appear so far. We are like a leaf in the dense jungle of the universe, appearing, growing and falling without any effect on the universe.
Universe
The universe has always been a vague concept in our mind, it seems to be a hand hidden behind the dark night sky, and it seems to be a vessel to incubate the solar system and the earth produced, perhaps we are too small, even with a rich imagination it is difficult to imagine what it looks like.
In physics, the universe is the general name of all space, time and matter, in which is full of all kinds of energy, such as electromagnetic radiation, dark matter, stars and galaxies are actually the energy of the universe, but in different forms.
As early as the Eastern Han Dynasty, the Chinese astronomer Zhang Heng made the following assertion about the "universe", saying, "The sky is like a chicken's son, and the earth is like a yellow chicken. The table of the universe is infinite, the end of the universe is infinite." And later on, the classic reading material for children's enlightenment, "A Thousand Characters", was written at the beginning of the book, "Heaven and earth, the universe and the universe. The sun and the moon are in the sky, and the stars are in the sky." It can be seen that, although people's observation ability was limited at that time, but the concept of the universe was deeply rooted in people's hearts early on.
As for when and how the universe was born has always been a mystery in people's minds, until the emergence of Einstein's general theory of relativity in the last century to give us a glimpse of two, this theory by quantifying some of the universe undetermined values, such as the speed of light, so that we have the opportunity to deduce the birth and evolution of the universe. The Big Bang theory, which followed, pushed mankind's understanding of the universe to another peak.
Many people call the world before the birth of the universe the "primordial world", where they believe that all boundaries are infinite, but there is nothing.
After this world appeared in the matter, named the "beginning particle", it reacted in this world and eventually exploded, thus tearing a hole, the beginning of the world began to occur in a series of explosions, eventually cooling planets and galaxies.
This "beginning particle" is about the Big Bang theory of the singularity. The Big Bang cosmology is a modern cosmological theory, which believes that the universe was formed in a dense and hot singularity expansion explosion, and that the universe was expanding during the evolutionary history from hot to cool.
As for the time of the explosion, they believe it happened 13.7 billion years ago, and we can still observe the "afterglow" of the big explosion through special telescopes. The main founders of this theory are Lemaitre, Gamow and Hubble, and Hubble's discovery of galactic redshift, which led to Hubble's law, is direct proof that our universe is still in expansion.
The Birth of Humanity
The birth of man has been a constant topic of debate since ancient times, from the religious proclamation that "God made man" to the creation of Darwin's Origin of Species, which broke the theological narrative and first explored the birth of man from a scientific perspective, a long process. That is to say, for a long time mankind was in ignorance, believing religiously that our bodies and even our consciousness came from the so-called "hand of God", but fortunately in 1871 Darwin's "The Origin of Man and Sexual Selection" showed us another way to explore.
Darwin's theory of evolution believes that we and other creatures in this world actually have the same origin, only we choose to develop and cut off different things in the evolution, resulting in our evolution into the present appearance. For example, according to Darwin's anatomical evidence. Our skeleton and monkeys, seals and even bats are able to correspond to part of the skeleton.
The human embryo is also initially very similar to the embryos of other animals and is almost indistinguishable. Many people simply interpret the theory of evolution as "Darwin said that man became a monkey", which is biased.
If we want to truly solve the mystery of human origins, we need to find more fossils. After the introduction of Darwin's related theories, many fossils have indeed been found around the world, and these fossils of ancient apes or ancient humans can be used as a basis for exploring the birth of human beings. For example, the discovery of Neanderthal fossils in Europe has pushed the historical process of our human emergence forward some more.
Later, the fossils of Homo erectus and Homo sapiens were found one after another, and the time of our birth has been constantly refreshed. The earliest human ancestor recognized by many biologists is the Lama ape, which lived around 14 million years ago and was first discovered at the northern border of India and Pakistan. This fossil was first discovered in the northern border of India and Pakistan, and was followed by a discovery in Lufeng, Yunnan Province, China, where the fossilized skull of the Lama archaeopteryx was excavated in 1980.
It can be said that the birth of mankind to the development of a number of obstacles, from our choice to develop the brain, give up something, the brain needs nutrients make the ancient human had to hunt often, simply eat wild fruit has been unable to meet our physiological needs.
Perhaps, given the circumstances, the choice to develop a brain is really a bad choice, why would you say that?
That's because the ancient times when wild animals were rampant, humans who chose to develop their brains were undoubtedly located at the bottom of the food chain, when the brain could only provide us with simple ideas, far less intelligent than now.
With other animals choose to evolve a strong body, hard armor and even wings to fly into the sky, ancient humans do choose some arbitrary. But also fortunately they chose to use nutrients to develop the brain, the real human evolution was born, so that our emergence is very accidental, if not then the part of the ancestors choose to develop the brain, now perhaps we are no different from other beasts.
The universe for mankind
It must be said that we were once still arrogant, placing our eyes on the acre of land beneath our feet, feeling that we were the masters of this world, an existence similar to that of God. But as we opened the window to observe the universe, everything changed, and we began to realize our own insignificance. The more we stood under the vast river of stars, the more we felt that human existence was just a small gravel. Perhaps we are not meaningful to the universe, but the universe is very significant to human beings.
Science was born out of mankind's desire to know and curiosity about the unknown, and after the birth of science, our knowledge of the universe has become more and more profound. So what is the meaning of the universe for human beings?
I don't know if you can remember the "Petri dish" we mentioned above, but the universe is a vehicle to nurture us, it may have its own consciousness, and even if not, it has acquiesced to many hidden laws after the explosion.
The reason we explore the universe is to find the mysterious law that is hidden in the depths. This law has no meaning for the universe itself, but all forms of energy in the universe are silently following this law, for example, stars are bound to evolve and age, or why the Milky Way spins the way it does, in essence there is a law that secretly governs everything.
If we break this law, it means that we have mastered the most basic laws, and then the unexplained mysteries of the universe, human beings, and consciousness will be solved.
From the birth and development process of the universe known to mankind now, the birth of mankind is "accidental", not deliberately arranged by the universe, the earth just happens to be located in the habitable zone, providing the conditions for the birth of mankind, from the birth of cells to the emergence of individual organisms also went through a long process.
As for the most ancient ancestors of human beings who chose to walk on land from the ocean and chose to abandon other priorities to develop their brains, it was all a choice by chance, so to speak, all kinds of accidents interlocked and eventually made us. Therefore, it can be said that the birth of mankind is a thousand times more fortunate than you buy a lottery ticket to win the first prize.
Humanity for the universe
After talking about the importance of the universe to human beings, let's talk about the meaning of human beings to the universe next. In fact, although we are very small and may not be able to fly out of this small cell of the solar system in our lifetime, unable to see the whole universe, but our existence is still meaningful to the universe. This is the latest "New Man Choice Cosmology" principle, which is developed on top of the human choice cosmology principle.
The new anthropogenic cosmology considers humans as the trend and direction of the evolution of the universe (at a particular stage) and recognizes humans as the inevitable product of the evolution of the universe.
Similarly, although our bodies are fragile and short-lived, it is our existence that proves the possibility of the universe evolving life, in other words, the existence of humans that can be used to explain some of the problems in the universe.
Man may be the product of a set of physical substances spawned by the universe between chance, but we are all products of the universe no matter what
. We are certainly not all of the universe, but even a tiny one like a cell can reflect a certain quality of the universe itself, so exaggerate to say that human knowledge of the universe is actually the universe's knowledge of itself.
Humans are trying to understand the natural universe, and they are also trying to transform it. So this forms the characteristic of self-transformation of the universe. The transformation of nature by human beings is actually the transformation of the universe itself, which is the self-transformation of the universe.
Concluding remarks
I believe that after reading the above discussion, we will have their own ideas, it is true that if humans disappear now, there is no impact on the universe, in this vast sea of stars, in addition to humans, there must be other "life" or "intelligence" can serve as the mirror of the universe.
Smallness and greatness, it seems, have been opposed since ancient times, but they appear to be fused in human beings. Human existence is a drop in the ocean of insignificance, and the proud civilization will be annihilated in the history of the evolution of the universe.
But smallness and greatness often appear together in our life forms. The great giants of thought and science, whose creations and visions were born in this small body, yet their theories contain an infinite universe, we look both strong and fragile, yet this paradox has created many miracles.
Don't think about what we mean to the universe, it's too deep a question. Just focus on our significance to the things around us. Every person is born with the expectation of parents, and every action of everyone actually has to drive the process of history, although we are all small cogs, but for the huge "history wheel", each cog rotation is the driving force to push it forward.
