【Maintaining Energy Balance Part I : Cosmic Part 维持能量的平衡上编-宇宙编】
Energy balance is another concept. First, we understand balance: The definition of "balance" in the Xinhua Dictionary: 1. The forces on each part of an object or system are equal, maintaining a stable state. 2. The two sides are equal in quantity, quality, or force, or cancel each other out. 3. Metaphorically, a coordinated and harmonious state. In-depth interpretation: when a system tends to or undergoes some unstable change, there is another change or variation to maintain the stability of the system, and energy plays a key role in this. Other definitions: balance refers to a dynamic or static stable state reached by interactions within a system or between the system and its environment; in chemistry, it is heterogeneous complementarity, and in physics, it is homogeneous uniformity. Here energy does not refer only to a quantity, but can be in different forms, such as forces: gravity, electromagnetic force, strong nuclear force, weak nuclear force; various forms of energy maintain the balance of a system, simply put, "maintaining energy balance." But the universe is not a single system; macroscopic and microscopic, world, all things, and various systems intersect complexly; as Chinese philosophy says: Yin contains Yang, Yang contains Yin, and the systems of the universe are constantly rotating, with dark matter and dark energy at work, so nothing is eternal. A single theory of Yin and Yang is hard to explain clearly in one article; it is enough to explain our world and maintain its balance.
Let us fasten our seat belts and set off.
According to the mainstream view, our universe was born in the Big Bang 13.8 billion years ago; before that, it was just a collapse, an infinitely small, infinitely dense singularity.
The scenario before the Big Bang: the dance of energy from "nothing" to "something"!
Modern quantum field theory holds that the pre-Big Bang universe was not absolute "nothing," but was filled with quantum vacuum — a state of lowest energy but with quantum fluctuations. Virtual particle pairs (such as positron-electron) constantly emerge in the vacuum, borrowing energy
