Not perfect "is not a pity

Hundreds of years ago, Newton told us that everything is held together by gravity, but Newton did not reveal the nature of gravity: how exactly does it work?

Einstein's general theory of relativity explains the nature of gravity. Einstein believed that there was no such thing as gravity, and that gravity was merely a manifestation of the curvature of space-time.

General relativity shows that space-time is not absolute or unchanging. Space-time is elastic, like a spring bed, and can be compressed, stretched, bent, and even torn apart.

Although more accurate than the description of the gravity, general relativity but now we still use Newton's theory of gravity, general relativity can better describe the strong gravitational cases world, but we all live in the low gravity world, so that Newton's theory of gravity is still dominates our lives, to put it bluntly, theory of gravitation is an approximation of general relativity.

Gravity rules our world, and the colorful world we see today was created by gravity, or rather its imbalance.

After the Big Bang, clouds of gas and dust molecules were scattered almost uniformly across the universe. In the process of continuous cooling, this uniformity is broken, some regions are more dense temperature, gravity will be more, there is a phenomenon of gravity imbalance.

This imbalance was crucial to the creation of the universe. If gravity were in balance, things wouldn't come together, stars wouldn't be born, and of course nothing would be here today.

And when the balance of gravity is broken, some places with strong gravity will slowly attract more matter, and gravity will get stronger and stronger and attract more matter, and so on and so on, like a snowball, with more and more effect.

As a result, it's easy to imagine that when the material accumulates enough to reach a critical point, a major event occurs: nuclear fusion, which also means the birth of a star.

I don't need to say enough about how important stars are to the evolution of the universe.

As you can see, the distribution of matter in the universe is imbalanced and imperfect, resulting in an imbalance in gravity, which in turn triggered a series of major natural events, leading up to the colorful world we see today.

So, everything we see today is due to the imperfect, irregular, or lack of order of the universe at its birth. We often yearn for a perfect world, but actually a perfect world is a castle in the air. Not perfect, to reflect the nature of the world.

So, if anyone ever accuses you of making a mistake, you can tell them out loud that it's good to make a mistake, because you and I and everyone else exist because of "imperfection"!

Einstein's space-time is not curved, but everything moving in space is moving in an inertial circle. Newton's apple did not fall to the ground because of the earth's gravity, but because the earth blocked the apple's inertial circular motion. Galileo's free-fall motion was correct. Unfortunately, the Leaning Tower of Pisa was only 30 meters high, and then the Earth stopped the free-fall motion of the two iron balls. Galileo didn't have to stretch his thinking and ask himself, what would it be like if the free fall of two iron balls were not blocked by the Earth? Now, let's demonstrate the mechanism of gravity through the whole course of free fall, the whole course of the falling orbit of the apple, and the whole course of the inertial circular motion of the object on the ground.

Gravitation is a heat parallel tendency, also known as entropy increasing tendency. It should be known that the gas or dust in the universe has a tendency to condense, and this tendency comes from expansion. The expansion speed is uniform and isotropic, but due to the different spins of the gas or particles, the inertial resistance produces condensation, which is called "birds of a feather flock together, people flock together". The aggregation of matter depends on the endowment of free particles. Under the action of the reference coefficient of cosmic expansion, the entropy increase is limited based on the difference of the endowment of free particles. Instead OF ASSUMING THAT REPULSION OF THE SAME SEX PRESERVES DEGREES OF FREEDOM (ENTROPY CONTINUES TO INCREASE), WITHDRAWAL OF THE OPPOSITE SEX PRESERVES GRAVITY (ENTROPY STOPS INCREASING AND TENDS TO DIE), SUCH AS THE STRONG NUCLEAR FORCE FORMED BY PROTONS, NEUTRONS AND ELECTRONS. Condensed molecules: single nature very moment are more molecular weight polymer. The reason is the increase of the opposite phase suction force, the decrease of degrees of freedom and the decrease of the repulsion force, which is determined by the entropy threshold. So obviously, because atoms clump together, molecules expand, gases or particles are happy and sand becomes a tower, the tower becomes a cluster, the cluster becomes a cluster, the cluster becomes a synthesis, and the universe is born. Birds of a feather flock together, and enlarge the aftereffects of gravitational and repulsive forces to accelerate cosmic ray expansion.
