Many people have imagined that the solar system, the Milky Way and even the universe in our place are just a cell of life structure, or it may be an atom. This is actually very similar to the scene at the end of the movie "Men in Black". The last scene is the Milky Way where we live. It's really just an alien toy ball. Of course, these situations make people's brains wide open, but they are impossible in physics.
The laws of physics are not immutable, but will change at different scales. The laws governing galaxies are completely different from those governing atoms. Imagine that an atom is like a solar system. Although it is really similar, the nucleus accounts for 99.99% of the total atomic mass, which is similar to the mass of the sun occupying most of the solar system. Electrons revolve around the nucleus, just as many planets revolve around the sun. The difference is that if two solar systems collide, then these planets will collide and break into pieces, and they must not fluctuate. But when two atoms collide, they may bounce off each other, or they may combine to form fluctuating molecules. And according to Heisenberg's uncertainty principle, we can't know exactly where the electron will go now. It can indirectly jump from Mars orbit to Jupiter orbit.
Quantum theory sounds strange, but it rules the macro world from the micro world. When studying chemistry, the chemistry teacher must have told you that two atoms can combine to form a fluctuating molecule because they can enjoy electrons between them. However, it is really wrong to say that two atoms share one electron. Because electrons can appear anywhere in two atoms today, we can say that these two atoms are bound together because electrons jump between them. This shows that without quantum theory, molecules would scatter and collide with each other, and nothing in the world would exist.
Natural growth or evolution system is like a huge network, so are human cells and the universe. Although the statement that the universe is a living cell can never be confirmed by scientific data, based on the above theory, we have reason to guess that the universe is a huge living cell, and human beings are only a trace element in this cell.
