First, let's talk about the universe. "Yu" refers to time, "Zhou" refers to space, and "Yu" and "Zhou" together are the time and space of everything. Before the formation of the universe, there was no time and space, and this state was what Laozi called "nothing" in Tao Te Ching. The universe is born out of nothing, forming "being", which is the mother of all things, and all things are born from it. And the whole process is "out of thin air".
Seeing this, is it a bit similar to the origin of the universe that our modern astrophysics says? The mainstream scientific community believes that our universe originated from the Big Bang, which was erupted by a singularity with extremely high density and extremely high temperature. After the explosion, the universe began to expand, with time and space, and also formed matter, which formed our universe today through continuous evolution.
However, the scientific community does not have a very reasonable explanation for the singularity before the explosion of the universe and why it exploded. It only gives a physical description that it is a thermal existence with infinite mass and infinitesimal volume.
However, this explanation is contrary to our existing physics common sense, because the greater the mass, the greater the gravity of the object, and the singularity, as the existence of infinite mass, should have infinite gravity. So how can such an existence explode? Even if it explodes, we should reunite at the moment of explosion. What force can compete with the great gravity and make it continue to expand for a long time?
Let's open a brain hole here. According to Laozi's Tao Te Ching, we know that the universe originated from nothing, and there is no time, space and everything. Then, we can regard the singularity mentioned in science as a kind of "nothing" state without mass and volume, so there is no such problem as the relationship between mass and gravity, because gravity itself is the law of the material world and may not necessarily apply to the "nothing" state of immaterial matter.
Then, if that singularity is "nothing", how did the universe "make something out of nothing"?
There are clouds in the Book of Changes, Tai Chi gives birth to two instruments, two instruments give birth to four elephants, and four elephants give birth to gossip. And two of them refer to yin and yang, which means Tai Chi gives birth to yin and yang. There is also a saying in Laozi's Tao Te Ching that "Tao gives birth to one, two, three and everything". It means that Tao is the origin of all things in the universe. Tao produces yin and yang, and yin and yang intersect to form tangible things, which is how everything is produced. Everything is cloudy and sunny, and forms a harmonious and even state in the interaction of yin and yang.
If this idea is used to explain the origin of the universe, then the universe is likely to start from the singularity of "nothing" and produce yin and yang. Yang refers to positive matter and positive energy, while Yin refers to antimatter and negative energy.
Everything is uncertain, which may mean that the material world we can see is actually the so-called positive matter, while antimatter is invisible to us. The harmonious and comfortable state formed by the interaction of yin and yang is very similar to the process of collision and energy release of positive and negative substances described by our modern science.
The collision of positive and negative matter disappears and releases energy, so in turn energy can be divided into positive matter and antimatter. That is to say, the singularity mentioned in science is not a kind of existence with high density, but a kind of existence in the form of pure energy, and based on this energy, positive and negative matter is born, and then everything in the universe is formed.
If this hypothesis holds, then our universe probably really originated from "nothing" as described by our ancestors, and everything in the universe originated from "nothing".
Of course, this may only be the author's speculation, or our ancestors really understood the mysteries of the universe, don't you think?
