The expansion of the universe
“Red The discovery of the phenomenon of”shift” reveals that the universe is constantly in motion, constantly expansion . So, is the expansion of the universe finite or infinite?
We As we all know, the universe was born in the Big Bang of Singularity. Before the explosion, the diameter of the singularity is so small that it can almost be regarded as a single point. But this point is very unusual, because it gathers all the conditions necessary for the creation of the universe, that is, matter and energy.
where There are matter and antimatter, and energy has energy and Dark energy. Generally speaking, matter is generally more than antimatter, and energy is generally more than dark energy.
here Here, we may wonder, why does the singularity explode? What is it that drives it to explode?
Front A question is relatively easy to answer. For example, a balloon, we continue to inflate it to a certain limit, it will explode and tear. In other words, the maximum accumulation and concentration of matter and energy promoted the occurrence of the Singularity Big Bang.
Then , What is the energy component that drives it to explode? How did it drive to produce an explosion? All this is not known, this requires continuous exploration by the generations.
odd After the point explosion, matter and energy continue to extend and expand into the void. The speed during this period is very fast, and it has reached the point where it can be calculated in light years. With the continuous interaction of matter and antimatter, the universe as we know it today has gradually formed.
The universe , Is the unity of material energy, space and time. Then, before the formation of the universe, that is, when it was still a singularity, have space and time been created? In other words, space and time were produced in the process of the Big Bang, or when the universe was formed.
this The problem seems simple, but it is actually very complicated. If space and time are produced at the time of the singularity, then to some extent, the singularity itself is a universe, but the universe is too small. Assuming that space and time were produced in the process of the Big Bang, how was it produced? We all understand that matter is in motion, and the movement of matter generates energy, and the form of material motion, It is space and time. In this respect, space and time arise from the movement and development of matter.
Then , Is the expansion of the universe finite or infinite? Let us assume that the expansion of the universe has a limit. We all know that the expansion of the universe, that is, the movement of the universe, movement requires energy, and expansion requires energy. In other words, the energy in the universe causes the universe to expand continuously. And energy is divided into energy and dark energy. We can be sure that as the universe continues to expand, energy will be consumed, but whether dark energy will also be consumed, or that dark energy only acts as an intermediary and does not consume it as a catalyst. What?
If Dark energy is not consumed, so it seems that only energy can power the expansion of the universe. According to Law of Conservation of Energy, energy is consumed, but another form of energy is produced. Here, we might as well call the former raw energy, and the latter as generated energy.
The universe Is there a boundary for the expansion? I think it is. Assuming that the expansion direction of the universe is one-dimensional, then the unexpanded and extended end is the boundary, and the expanded and extended end can also be called the boundary, but the boundary at this time is constantly extending, evolving, and in constant motion. Assuming that the expansion direction of the universe is multidimensional, then the universe has multiple boundaries, and these boundaries are constantly developing and developing.
All in all That is to say, no matter how the universe moves or expands, it has boundaries.
Then Since the expansion of the universe has a boundary, how can the boundary be judged?
The universe Among them, matter has matter and antimatter, so why is antimatter so much smaller than matter? We all know that matter has mass, so does antimatter also have mass? If antimatter has mass, then which mass is greater than the mass of antimatter and which is smaller?
For For the first question, let’s make a bold assumption. Antimatter is only smaller than matter, which may be related to its mass. That is, the mass of antimatter in a unit is greater than the mass of matter in a unit. In order to maintain the balance of mass in the universe, the amount of antimatter should be less than the amount of matter. Of course, this assumption is based on a condition that antimatter has mass.
如若Antimatter has no mass. This assumption is wrong. Although all matter has mass, antimatter is different from matter after all.
If Antimatter has no mass, so what kind of role does it play in the universe? Or is it that it is similar to dark energy and may have a transforming and catalyzing effect? If it really only has a transformation effect, then the antimatter will not be consumed.
Celestial bodies Most of the production of planets comes from the collision, squeezing, and explosion between matter and matter. So, will matter and antimatter also collide? Will the collision between antimatter and antimatter also form celestial planets?
These The problems are all based on the premise that antimatter has mass. If antimatter does not have mass, what kind of scenario is the collision of antimatter and matter, and the collision of antimatter and antimatter?
