Yes, the universe is still extending. The current view is that the universe was born today in a great **. And the universe as the name suggests, "Huainanzi Yuan Dao Xun" Note:
The four directions are said to be the universe, and the universe has been said throughout the ages, in order to metaphorize the heaven and the earth. That is, the collective term of time and space. Then the continuation of the universe is the continuation of time and space, so the reason why we still exist is because time and space have been constantly moving, giving us the meaning of existence.
So when the universe stops expanding, in fact, our life has come to an end, time has stopped, and life has stopped continuing! So we won't wait until the universe collapses to a point to perish (the above is a personal opinion).

Personal understanding and experience for your reference:
The universe is like a wheel that continues to reincarnate, and the origin of the universe should be that axis, the closer to the center of the axis, the shorter the time, and the higher the dimensional layer. Conversely, the farther away from the axis, the longer the time and the lower the dimension layer. The realm of a Buddha is like an axis that does not move, and although it is said that it is not moving, it can clearly know everything in the universe.
This is basically the principle of the six realms of reincarnation and the ten-dimensional world that the Buddha said.
You must know that life is self-inflicted, and if you do good, you will receive good rewards. If you do evil, you will also have to suffer bad retribution. Therefore, fate is in one's own hands to a certain extent, and the way to change one's fate is to do good deeds and accumulate virtue.
We humans and most of the life on Earth live in a space below the fourth dimension, firmly bound by time and space. If you want to jump out, you have to "round up".
From the documentary "20 Years of Hubble", we know that the universe has gone through more than 13.7 billion years of history, and after a long period of expansion, it may have to face space compression. If the universe was born from a point of infinite mass, then it means that after a few years, the universe expands to the limit, and then has to be compressed, and finally becomes a point. Just as we humans breathe, life and death, this is the breath and life and death of the universe.
In the end, there is no life and death, just a cycle of life and death.
This is why, in Professor Zeng Shiqiang's "The Mystery of the Book of Changes", it is said that the Book of Changes is a treasure book to unlock the code of the universe. The yin-yang Pisces diagram represents the symbol of the password.
It is also explained that if you want to experience the state at the beginning of life, you can try to practice fetal breath, which is there.

Yes, the universe is expanding all the time. When it reaches a certain point, it shrinks, and then **, and forms a new universe. Re-expansion ———
-
There is no answer to this question for the time being, but it is still being studied.
-
There are three possible modes of development of the universe, and there is little difference in the early stage of the universe's development, and different results will appear in the later stages of evolution. At present, the universe is in a stage of expansion, and it is not yet possible to determine what kind of system the universe is.
Open Universe: The universe expands after it grows, and the expansion force of expansion is much greater than the gravitational force, and the universe will expand endlessly. The continuous expansion of the universe leads to an infinite increase in the entropy of disorder, the universe develops to the most chaotic state, all celestial bodies decompose, and only photons and leptons are left in the universe, entering a state of heat death.
Balancing the Universe: The expansion force of the expansion is about the same as the gravitational force, so the expansion will be slower and slower, and finally expand at an extremely slow rate.
Closing the universe: The universe expands after it is large, and the expansion force of expansion cannot compete with the gravitational force, so when it reaches a certain level, the expansion tends to stop, and thus begins to shrink in the opposite direction of expansion. Finally, the universe collapsed into a singularity after the Great Squeeze.
From the point of view of increasing entropy, an open universe system is more reasonable, while philosophy is more in favor of a closed universe system. But the order of one system comes at the cost of greater disorder in other systems, so it makes more sense to open the universe.

The universe is very vast, and with our current human technology, we cannot truly ** all the things and phenomena in the universe. The universe is constantly changing, and we humans can only monitor the changes that are happening in the universe, but we can't investigate these changes in depth, we can only wait and see the changes in the universe and speculate through all our scientific measuring instruments. Recently, scientists discovered that the universe has been expanding outward, and once this phenomenon was discovered, experts made various speculations about it.
Until now, we humans have not been able to correctly deduce how big the entire universe really is. The universe is boundless and mysterious, so even if we use current technology to detect that the universe has existed for 93 billion light years, we can't know how deep the end of the universe is. Some scientists, through their guesses or some actual satellite measurements, are unable to accurately determine the area of the universeBecause our universe is still changing, constantly expanding outward
Scientists have found that the area of the universe is expanding and expanding, which means that the area of our universe is also expanding. Then some people will ask, the universe is constantly expanding and expanding, so is it expanding and expanding from the beginning? Where is the universe expanding?
What's there?
In fact, without scientific explanations, we also know that the universe is constantly expandingIt proves that there is another space beyond our universe。We know there is such a space, but we don't know what the mystery of that space is. Scientists speculate that there is another universe besides the universe through the big ** theory.
Scientists believe that our universe is not only limited to its current area, but may also be expanding outward, compressing other universes and gradually expanding its own area. In order to maintain the status of the current universe, the universe must continue to expand and expand, compressing other universes and making other universes smaller universes.
Then many people will ask, is there an end to the universe? Is there an end? Scientist Penrose believes that the universe is actually the same as our human life, and our human life has to go through the process of birth, decline and death
The existence of our human beings is constantly cyclical, and there are people who die every day, and there are people who are born every day. Therefore, if there is a second universe in the world, then after the death of the first universe, there may be the birth of another universe. So from Penrose's scientist's point of view, there will never be an end or end to the universe.
-
No one knows exactly where the end is, because it collapsed in the process of continuous expansion. It is also starving to be extended, so no one knows how to reach ** in the end.
-
There should be no end, now our scientific and technological level is very limited, there is no way to solve this problem, and the universe is very vast.
-
The universe should have no end, the universe is very large, and there is no end to the universe at present, there should be no end.
-
If the universe continues to expand, I think it has no end, because the universe itself is an infinite existence.
-
There may be no end, because the universe is always changing, and we humans have never groped for the edge of the universe.
-
Our universe is spreading outward away from the Milky Way at a rapid pace, just like the spread of flowers. The space between galaxies is also expanding.
A scientist once used the analogy when he said, "If you compare galaxies to raisins, then the universe is a bread of expanding raisins that has been baked." This means that the size of the raisins has not changed, but the space (bread) has expanded.
The speed at which the universe expands is called the Hubble constant, and scientists have found that the universe has expanded by 10 billion to 15 billion years. In the vicinity of galaxies 10 million light-years away from Earth (1 light-year = 9,460.8 billion kilometers), the rate of expansion in one second is 184 kilometers. So, what is the Andromeda star cluster at a distance of about 2 million light years?
Do the math, please. 1 second should be about 37 km.
Hope it helps! Please, give me the best!
-
According to today's instruments, the phenomenon of redshift can be detected, and the phenomenon of redshift can be determined to be expanding.
-
The redshift of the galaxy's spectra suggests that the star system is moving away from us, and Hubble found that the speed at which the galaxy recedes is proportional to its distance. This makes the farther away from us, the faster the galaxy moves away from us; This has evolved into a big ** faster than light, and even the universe is expanding faster and faster.
It is impossible for the universe or nature to produce more than the speed of light alone, but there will be two or more phenomena in the universe or nature that jointly produce more than the speed of light, for example, when launching a satellite, the relative velocity between the satellite and the sunlight exceeds the speed of light; If a flashlight is held at the sun, the relative velocity between them is twice the speed of light. But none of them produce more than the speed of light on their own, but two together produce more than the speed of light. In the universe, if the expansion rate between the earth and the moon, between the sun and the earth, and between the galactic heart and the sun is the speed of sound, then the moon is expanding at three times the speed of sound in the Milky Way, but the earth, the sun, and the galactic core, each of them does not exceed the speed of sound.
At the same time, the moon is only 20,000 light-years away from the center of the galaxy, and our observation of the universe is 13 billion light-years, especially the error of observation and theory, so that the phenomenon of the sum of multiple velocities is challenged, but these cannot shake the reality that the universe is still expanding.
-
As long as the energy of the universe does not disappear, various reactions will continue to occur, and once the energy disappears, it will shrink abnormally, and I believe that there will be energy beyond the galaxy that is faster than the speed of light.
-
According to scientists, the universe is indeed constantly expanding.
-
Not only is it expanding, but in recent years, it has been observed that it is expanding at an accelerated rate.
-
The expanded theory is based on the relative observation point of the Earth or the Milky Way, and most of the stars on Earth are observed planets and galaxies leaving us, so it is believed that the universe is in a period of expansion, but this theory has great doubts:
1。The center of the singularity is **?
2.The movement of objects is relative, the stars and galaxies leave us, is this movement away or closer (assuming that the universe has a center)? Can't we be self-centered and think that this movement is in expansion, and the direction of movement may also be contraction?
3.The singularity theory may be able to explain the development of galaxies and stars after the big **, but it cannot explain the situation before the big **. Until now, no convincing evidence has been found.
4.Singularity Theory The theory of the great ** holds that the universe starts from the big **, and this theory has an absolute tendency, which is in obvious contradiction with the philosophical belief that everything in the universe is a relative existence.
Human beings are so small relative to the universe, and their understanding of the universe is still extremely limited, and the theory of singularity may only be able to analyze a certain stage of the evolution of the entire universe but not all of them.
The space and time of the universe are infinite, and the cycle of life and life is endless, and galaxies, stars, and planets develop from birth to extinction, and then start another cycle again, and the cycle repeats.
-
Because the universe that general relativity describes to us is a non-static universe that either shrinks and becomes smaller, or expands and expands. And it tells us that our universe must have a beginning, this beginning is an infinitesimal singularity, then it is impossible to continue to contract, on the contrary, it can only produce ** and expand, and continue to expand, which is also in line with the thermodynamic entropy of the whole from order to disorder, in line with the direction of the time arrow of the universe, and more in line with the emergence of intelligent life.
-
Of course, it's expanding, because humans are observing a lot of stars moving away from us.
-
Neither enlarged nor shrunk. The universe in four-dimensional space is one entity. There is no such thing as enlargement or contraction.
-
There is shrinkage in magnification, and the universe is like a box, which Newton said. The contents of the box are no bigger than the box.
-
The expansion of the universe is expanding through the redshift of the spectral lines is detectable.
-
That's not expanding or shrinking, it's expanding. This can be illustrated according to the redshift.
-
For now, the universe is expanding at an accelerated pace. It was discovered in 2011 by astrophysicist Sal Polmatt of the University of California, Berkeley, Brian Schmidt of Australia, and Adam Rees, an American scientist, based on observations of distant supernovae**.

Redshift in cosmology.
There are 3 types of redshifts: Doppler redshifts (caused by the radiation source moving away from us in a fixed space) and gravitational redshifts (due to the gravitational redshifts of photons).
from the outward radiation of the gravitational field) and cosmological redshift (due to the expansion of space itself).
At the beginning of the 20th century, American astronomer Edwin Hubble discovered that the spectral lines of most of the observed galaxies were redshifted. This is due to the expansion of the universe, which elongates the light waves emitted by celestial bodies, and the spectral lines "turn red", which is called cosmological redshift, and thus derives Hubble's law.
In the early 20th century, Schlifer, Harper and others first measured the redshift and blueshift of galaxies outside the Milky Way, and they initially explained the redshift and blueshift caused by the Doppler effect, but later Harbour discovered that there was a rough correlation between distance and redshift, and the farther the distance, the greater the amount of redshift. Theorists almost immediately realized that these observed redshifts could be explained by a different mechanism, Harbher's law, which is the correlation between the interaction between redshifts and distance, which needs to be explained using the cosmological model of general relativity of spatial scale expansion. As a result, the photon is stretched as it passes through the expanding space, creating a cosmological redshift.
This is different from the redshift due to increased velocity described by the Doppler effect (this is the Lorentz transformation), where the photon is redshifted by an increase in wavelength due to the expansion of space instead of momentum and energy between the light source and the observer.
If you don't understand, you can look for me.
Human doubts about the universe often stem from the ambiguity of the concept of the word "universe". The real scope of people's definition of the word "universe" is the sum of the objective world, but in fact, people's knowledge and understanding of the "universe" is actually the sum of sensory knowledge. What is beyond the universe? >>>More
No, at least it won't be destroyed while you're still alive. As for the future, that's unknown.
There are three possible models of cosmic development, which are not very different in the early stages of cosmic development, and have different results in the later stages of evolution. At present, the universe is in a stage of expansion, and it is not yet possible to determine what kind of system the universe is. >>>More
At least at the current level, it is impossible to actually prove what the universe is like, everything is based on theoretical speculation. In fact, because the level of human technology has not yet reached that level, it cannot be confirmed. It's like if you haven't seen God, can you say that God must not exist? >>>More
Hot and cold are opposites and unity, there is no cold without heat, and there is no heat without cold. >>>More
