A Brief History of Time could also explain why there is so much matter in the universe. In the universe that we can observe, there are roughly 100 billion, billions (1 followed by 80 zeros) particles. Where do they come from?
The answer is that in quantum theory, particles can be created from energy in the form of particle anti-particle pairs. But this only raises the question of where the energy comes from. The answer is that the total energy of the universe is exactly zero.
The matter of the universe is made up of positive energy; However, all matter is attracted to each other by gravity. Two pieces of matter that are close to each other have less energy than two pieces of matter that are very separate, because you have to expend energy to overcome the gravitational pull that pulls them together to separate them. In this way, the gravitational field has negative energy in a certain sense.
In the case of a universe that is roughly the same in space, one can show that this negative gravitational energy just cancels out the positive energy represented by matter, so the total energy of the universe is zero.
Twice as many as zero remain zero. In this way, the universe can double its positive material energy and negative gravitational energy at the same time, without breaking its conservation of energy. This did not happen during the normal expansion of the universe.
At this time, when the universe grows larger, the energy density of matter decreases. However, this did happen during the boom. Because when the universe expands, the energy density of the supercooled state remains the same:
When the volume of the universe doubles, both the positive matter energy and the negative gravitational energy are doubled, and the total energy remains zero. In the inflationary phase, the size of the universe increases by a very large multiple. In this way, the total energy that can be used to make particles becomes very large.
As Guth said, "It is said that there is no such thing as a free lunch, but the universe is the most thorough free lunch." ”

The matter of the universe is from the matter itself, from the most primitive particle-free structure, through the continuous squeezing of matter, the various substances that we can observe now, so it can also be said that it is burned leftovers, or born in combustion.

The origin of the universe, the problem of asymmetry of positive and negative compounds, whether there is a mutual influence that violates the conservation of baryon numbers, and the problem that many particles violate the symmetry of cp. The latter two important questions are that the Standard Model is not yet perfect, that is, there are still particles that everyone has not yet discovered to describe some conditions of the universe.
To a large extent, the planets make up your stars, and the planets make up your universe. Antiprotons, neutrons, and electronic components are the basic elements that make up everything new in the world, and they give mechanical energy to all the planets and stars in the universe. At the beginning of the universe, there must be a violation of the conservation of baryon number (you can master the conservation of mass, baryon is what we often call antiprotons, neutrons) of the interaction, I think this is very easy to grasp, everyone knows that compounds are unlikely to fly out, that is to say, the universe at the beginning of the baryon number is 0.
So you need a mutual influence or particle that violates this law of motion, which also means that you can get a lot more antiprotons than antiprotons. Contrary to the problem of conservation of baryon numbers, it is inferred that under the extremist norms of the beginning of the universe, an antiproton can decay into several leptons, thereby damaging the conservation of baryon numbers and leptons, but everyone has not observed such a thing today. In the 20th century and 60th century, everyone discovered particles composed of chia atoms:
K long-lived lock, there is a small probability that a broken CP symmetry will be found in nuclear decay.
This shows that the nuclear decay of the k-long-lived lock is substantially different from the decay of its antiparticles. If this had happened in the early stages of the universe, everyone would have gotten a lot of compounds instead of antimatter! The origin of the components of the universe, which experts call baryon asymmetry, is the second most difficult mystery in cosmology, after "why does the universe exist".
If we could answer this question exactly, it would be the most news coverage of cosmology since the discovery of dark energy in 1998. In general, to solve this problem, we must have new physics, we must have new particles, and we must constantly improve the Standard Model.

I think it's caused by changes in the atmosphere and the magnetic field. If there were no atmospheric magnetic field, there would probably be no matter in the universe.

These substances may be made up of some matter, or they may be formed through the universe.
-
Because after the temperature in the universe has dropped to a critical point, matter begins to convert from energy to mass.

The matter in the universe comes from **, this should be the biggest mystery, especially the rocks, magma, soil, water and gas that are born on each planet, and they cooperate quite closely with each other, there are mountains, seas and plains, etc., as for the matter that only came after human beings, it was later created by human beings using wisdom from the original substance, because human beings still have to survive.
But the congenital material comes from **, it can't be a great god who plays magic to conjure it, like Nuwa can create people, everyone knows that magic is fake, although I can't understand it for a while, but one thing is very clear, the things that are conjured up are originally there, but I don't know that the magician put it in ** at that time, just ask, if the things that are conjured up are not there in the first place, then the magician can't change them no matter how capable he is, in the final analysis, the original thing, that is, the substance came from **.
It's a long story, let's start with the universe, where did the universe come from, according to the theory of the universe, it is a singularity with infinite mass density and infinitely small volume, just like a monkey popping out of the crack in the stone, and finally this monkey becomes powerful and omnipotent, the universe may be the same, the original matter is gathered in the singularity, and only after the first has an infinite cosmic space, and it is also expanding at the speed of light, and the original matter of different sizes in the space is also flying around in the vacuumAfter tens of billions of years of cosmic gravitational consolidation, they slowly combined into spheres of different sizes.
Why are they all round, because all the matter in the celestial body is rotating, so the spheroid body is the main characteristic of the universe, and it is convenient to rotate, all kinds of planets through continuous rotation make all kinds of original substances have an organized home, such as stars, planets, etc., but also galaxies, star clusters, etc., and finally formed the current shape, for example, there is the Milky Way, the Andromeda Galaxy, etc., and then there is the solar system, and the solar system has eight planets revolving around the sun, At the same time, there is life on the rotating earth, and now there are human beings and all things, and so on.

The matter in the universe should be created when the universe is large. When the universe was large, a lot of molecules were produced, and matter was formed after encountering a magnetic field.

Where does the matter in the universe come from, this question has not yet been answered accordingly, because this matter is still under investigation between the husband and wife, but I think that all the matter in the universe is not created out of thin air, because these substances are relative, and the total amount of matter in the universe is a relative mass, so I think the universe is very magical.

A new theory of physical unity: all things in the universe, including all the microscopic particles and macroscopic and cosmic material bodies that have been discovered, are organized, combined and constructed step by step and at the first level under the constraints and control of environmental conditions and probabilities.
Microscopic particle fragments and macroscopic matter fragments are different from stable and self-consistent particle systems and cosmic star systems.
The smallest and most basic ground state quantum of the universe is filled with the cosmic space and the mass and non-mass matter body, so it is also the most basic (quantum) field medium that fills the cosmic space and the microscopic and macroscopic matter, so it must also be the only and unified medium field that can bear the four physical forces and can be transmitted.
It is the basic quantum medium that is full of the universe and the mass of microscopic particles and the material system of stars, and it is also the only common component of the organizational structure of the magnetic field "magnetic field lines", the electric field "power lines", the strong field "strong lines", the weak force field "weak force lines" and the gravitational fields "gravitational lines and gravitational nets" in the universe and microscopic particles. Although the various lines of force that make up them vary in organizational shape, size, and characteristics.
The essence of space-time: It is composed of the most basic origin of the quantum medium of the size of the superposition of the "space-time force network" structure, which not only penetrates through the material body, but also extends into the large-span space of the universe, although it has no mass, but has the energy with the restrictive nature equivalent to the huge mass, the size of the universe material system, are in the orbit range under the constraints of the space-time force network, running regularly. The variation of the local density of the quantum force line network leads to the curvature of space-time locally.
It is further determined that the mysterious and unpredictable "dark matter" and "dark energy" are also the most basic spatial quantum mediums that are spread throughout the universe and form the "space-time force network". Although they do not have gravitational mass, they do have the function and energy of gravitational and repulsive forces.

Generally speaking, they are all made of **, and there are also a lot of electrons and ions in the universe, including some dark matter and dark energy.

In a sense, we are all stellar dust. Some of the hydrogen originally synthesized by the universe formed stars, and some combined with oxygen to form water. The next time we drink water, let's not forget that the hydrogen in the water molecules is very old, it comes from 13.8 billion years ago.

The matter in the universe should be **in a cosmic great**, and after this great**, these substances in the universe are produced, which increases the diversity of the universe.
-
Matter is the general term for all things, and this concept is drawn from them, so that matter can neither be created nor disappear. Matter exists forever.
-
The energy fragments produced when the universe was big before, the universe must have been nothing before, and slowly formed the current universe through the transformation of time.
-
Matter in the universe is converted from the energy of the universe. Matter has three characteristics: mass, space, rest, or finite velocity.
The mass of matter is transformed from that part of the cosmic energy that is not fully released into velocity; The space occupied by matter is caused by the spin and revolution of this part of energy; The finite velocity of matter is when matter exists well below the speed of light and is close to rest, otherwise there would not be so many square roots of medium velocity to convert to mass.

Where does the matter in the universe come from?
How did all the matter in the universe come into being? Did it come out of nowhere?
The universe is divided into large universes and small universes, the boundless ones are called the big universes, and the boundless ones are called the small universes, and the large universe is composed of a vast number of small universes. >>>More
This is the problem of gravitation, there is a gravitational attraction between any two objects, and the reason why there is an atmosphere around the earth (the difference between vacuum and non-vacuum is whether there are gas molecules in a particular space) is because of the attraction of the earth to the atmosphere (the greater the mass of the object, the greater the gravitational pull). The mass of the Sun is greater, so it can attract the 9 planets around him, and the mass of the Earth is smaller, so it can attract the Moon around him. And stars (such as: >>>More
For Marxist materialism it is truth, unconditionally absolute.
In the solar system, the sun is the center, but the solar system is only a galaxy in the universe.
