According to the current mainstream view, the universe was born with the singularity "big**" hundreds of millions of years ago, and the cosmic redshift phenomenon and the cosmic background microwave radiation are the two main evidences of the cosmic greatness. Of course, the universe is still one of the most accepted hypotheses. The current observable universe is about 93.9 billion light-years in diameter, and the unobservable universe is at least 23 trillion light-years in diameter.
Now that mankind understands the beginning of the universe, that is, it originated from a singularity, then the end of the evolution of the universe is a new problem. Where is our universe headed?
I have seen a short science fiction ** by Da Liu, which is about the ending of the universe. The expansion of the universe is likened to an apple being tossed on the ground. At the beginning of the ascent there is a maximum initial velocity, which gradually decreases with the ascent velocity, which is very easy to understand, that is, the direction of motion of the object and the direction of force are opposite, and the object does deceleration motion.
When the apple rises to the highest point, the speed drops to zero and begins to fall, at this time the apple begins to accelerate until it falls to the ground at the maximum speed.
Then our universe is such a model according to the conventional idea, in 100 million years ago, all matter was given an initial velocity and began to expand and escape, but under the effect of its own gravitational collapse, all matter should slow down until the velocity becomes zero and begin to "collapse", which is a cyclical process (the universe changes from small to large and then to small).
But this is not the case, and at the end of the last century, astronomers around the world were thinking about measuring the expansion rate of the universe, mainly by type Ia supernova explosions, which are special and generally occur in binary star systems. When a star evolves into a white dwarf later in its life, the white dwarf will continue to absorb material from its companion star, and eventually the white dwarf will have a supernova explosion.
Astronomers have found through continuous measurements that the universe has been decelerating and expanding for 7 billion years after the big **, and suddenly at a certain moment, under the influence of a certain mechanism, the universe began to expand at an accelerated pace, as if there was a "pushing hand" pushing the universe to accelerate its motion. Finally, scientists came up with a new concept, calling this invisible "pusher" dark energy. Because of the existence of dark energy, the universe is expanding at an accelerated pace, and the final result of the universe is likely to be a state of "heat death".
The black hole of literature and science, the **** network invasion and deletion.

Answer: Everything in the world follows the law of motion and change.
The universe also follows this law, and astronomers have come to the conclusion through continuous measurement experiments: the final result of the universe is likely to be a state of "heat death".
-
The universe will change like this, because they will expand vigorously. It's going to get smaller again, and that's the cycle. So what will become of the universe in the end, it is likely to be destroyed.
-
Definitely! The universe could never have come into existence out of nothing, only once. The universe must have skyrocketed from an infinitesimal singularity to infinity, and then contracted from infinity to infinitesimal singularity, an infinite cycle.
-
The universe will only become more infinite because it is constantly expanding, beyond human imagination. There are many mysteries waiting to be solved in the universe, and its vastness has fascinated countless scientists.
-
The universe is endless, and it is getting bigger and bigger, it will not change from big to small, but it will become more and more powerful, this is the mystery of the universe, and the universe is ever-changing.

The universe is an infinite spheroid, the universe has always existed, but the universe has two major spaces, one is the unchanging material space, the other is the changing material space, the unchanging material space is infinite, it surrounds the finite changing material space, we can only live in the changing material space, and there are also two major spaces in the changing material space, <>
It is the invisible material space, it is the visible material space, and now the invisible material space surrounds the visible material space, that is to say, the infinite unchanging material space, the invisible material space, the invisible material space, and the invisible material space, the visible material space. Now in the middle of the visible material space and the invisible material space, there is still a fire burning! This is the reason why all the planets rotate and the universe expands as we see it!
Because the burning fire can transform the invisible matter into visible matter, the visible material space is expanding, and the invisible material space is shrinking, until the visible material space occupies 100% of the material space, and when the material space is changed by 100%, the invisible material space is zero, and then the visible material space begins to shrink, and the invisible material space begins to increase, and then the burning fire can transform the visible matter into invisible matter, and there will be white holes, <>
When the light disappears, the universe appears static for a moment, absolute zero appears, the singularity appears, the singularity is the smallest particle in the universe and closest to nothingness, and at this moment, the singularity, ignites and rotates, it is the smallest small spark of life, followed by a small fireball and rotates, then a large fireball and rotates to a very large fireball and rotates, to a small ** and rotates, to a large ** and rotates, to the visible matter generation and turns, and now and rotates ......

For the whole universe, all our knowledge seems so poor, and any imagination seems so pale! Faced with the universe, we can only say, "I want to know, but I don't know yet!" ”
The question of embracing the Lord is actually a philosophical question with no answers, boundless and unverifiable. If the photon had intelligence, it would know the secrets of the universe better than we do, because it can easily navigate the microcosm, while we humans cannot, and can only feel helpless like a blind man swimming in space.
But as far as the concept of "universe" is concerned, its literal meaning has already shown that it is an all-encompassing space-time system, since it is all-encompassing, then naturally it should be boundless, and all existence belongs to the universe, that is, there should not exist at all the term "outside the universe", but this is only the logical result of pure rational thinking, just like we study the coordinate system, where is the end of the coordinate axis? Where is the end of the number?
In contrast, the modern popular theory of "cosmic expansion" seems to have changed the concept of "universe", and its meaning is no longer an all-encompassing space-time system, because in order to expand, nature needs to provide it with excess space [strictly speaking space-time], so that there will naturally exist a part "outside the universe", otherwise it will not be able to expand. What's more, Einstein's theory of relativity can also bend our space-time, and these advanced theories are like magic that take us into a fantasy world. It's really high!
Think about it, isn't that the truth?
If you invite the world's greatest mathematician to the world's most advanced computer, ask him to express the scale of the universe with the largest number known to mankind, and let all mankind be his assistants, and keep helping him add "0" to this large number, what will be the final result of the calculation? The result will be "no result", and humans will never be able to figure it out, because the problem itself is not a math problem.
-
These basic concepts are hypotheses that modern science has not yet been able to prove. The most basic idea is a kind of faith. Faith is a choice.
Beyond the universe is the anti-universe; The universe is infinitely large, and elementary particles are infinite time and space are all forms of matter existence, which are the parameters and coordinates for measuring motion. The external force is relative to the internal force.
-
The universe does not change from infinity to infinitesimal to infinitesimal in the first place. I think that the universe is a very mysterious space, and there are many things that our scientific research methods cannot determine, so it will not easily undergo qualitative changes.
-
Yes, because the universe is a moving space, and after a long period of motion, it is very likely that it will become infinitesimal.
-
Of course not. Because the universe is infinite, the universe has no boundaries, and it will not become smaller at all.
-
The question of whether the universe is infinity or not has not yet been answered definitively. Judging from what we know so far, the universe is very large, far beyond the scope of our imagination, but we are not yet sure whether the universe is infinite.
According to astronomers' observations and calculations, the universe is constantly expanding, and different parts of the universe may expand at different rates. This makes it difficult to determine the exact size and extent of the universe.
-
Yes, the universe is infinite. Scientists have discovered that the universe is home to clusters of galaxies billions of light-years small, which are distributed over larger and greater distances. Therefore, the universe is extremely vast and infinite.
-
Judging from the currently known samples of the universe, the universe seems to be closed and unbounded, and the sedan wheel is infinite. When we try to understand its boundaries, there are always new "slices" of the universe that appear due to the curvature of space, which makes the universe seem infinite.
-
Is the universe infinite? For the current human beings, whether it is space navigation or telescope observation, the universe is infinite, no matter how hard the current human beings try, they cannot know the whole picture of the universe, only that it is still endlessly expanding faster than the speed of light.
Modern astronomy believes that the universe came from a great ** 13.7 billion years ago; According to the latest astronomers' "edges" device in Australia, it is said that it detected a faint signal from the first star, which came from the earliest star in the universe: only 100 million years ago, that is, 13.6 billion years ago.
At present, the observable universe of human beings is 93 billion light years, and in fact, we can only observe the scene at the beginning of the universe 13.8 billion years ago, plus phenomena such as the expansion of the universe, and the observable range is calculated to be 93 billion light years, which is the limit that human beings can observe. And this range may only be the current limit of human observability, due to the size limitation of human optical telescopes and the vastness of the universe, no matter how far the signal can not be detected, the universe is unimaginably large, that is, "infinity", and such a large universe it is still accelerating expansion, it is not too much to say infinite.
However, scientists believe that the universe is finite but boundless, finite means that although the universe has been expanding, it has not been formed for a long time, and boundless is the universe may be similar to the earth, where does the spherical arc come from, and it may go from one direction or come back from the other. The universe is very large and has many existences that human beings do not know or know very little, such as black holes, dark matter, and dark energy, which cannot be observed at present, and may not be observable in the future.
Fortunately, human beings have mastered the means of science, inducting principles from the known, speculating on the unknown, and continuing to observe the unknown with the progress of observation technology to verify the unknown and the existing conclusions, and science continues to develop.
-
Not necessarily. If the grand theory of the universe is a perfect theory of real existence, then the universe is finite. But if this theory is not perfect, then the universe may be infinite.
-
Yes. Because the universe is boundless and has no boundaries, and humans have not discovered the edge of the universe, the universe is infinite.
-
No, the universe should also have its boundaries, but with our current level of technology, it can't be detected.
-
I believe that the vast universe should be boundless, endless, beginningless, and infinitely large. The universe already contains everything, and there is no question of internal or external, origin and extinction at all. The universe is infinite in space and has no beginning or end in time.
No matter which direction you go in, it should be endless and endless, and it cannot be blocked by anything, which is the infinite cosmic space. I think it's absurd to think that the universe is boundary, and if the universe is boundary, what is that margin? Is there no beyond the margins?
And since there are edges means that there will be edges, this question is actually difficult to justify, how can people who say that the universe has an end explain it? The only thing that makes sense is that the universe is infinite and infinite! The universe is mainly composed of infinite space, how can an infinite space have the question of origin and extinction?
Matter in the universe can only be in an infinite cycle, endless and endless. It can be said that the infinite universe is indeed unimaginable to us, and it has long been beyond the scope of human cognition! But this is the universe, a mystery that humanity will never be able to solve!
Finally, I would like to emphasize that strictly speaking, the universe can only be regarded as a hypothesis, and there are still many questions about whether the universe has really happened, such as the so-called singularity is a very absurd singularity, how big is this singularity?How long has it been around?Why all of a sudden?
I'm afraid no one can tell. So don't take it too seriously!In addition, the understanding of the universe is inconclusive, and anyone can boldly express their opinions, and I hope you don't have to worry about anything.
At present, the scope of the universe observed by human beings is finite, and no one can know the actual size of the universe, and the possibility of infinite scale cannot be ruled out. >>>More
This is a dirchlet integral, which is more cumbersome to calculate, and has to be calculated using the integral with parametric variables.
In the force analysis, the stiffness infinity rod is regarded as a "passive rod", that is, the ordinary rod bears how much bending moment it bears, and it is regarded as an ordinary rod fixed at both ends If there is no bending moment at the end of the ordinary rod, then the stiffness infinity rod has no bending moment at that end. >>>More
Solution: Might as well set: - x1 x2 1
