How long does the universe have to live? Where to draw conclusions?

The life span of the universe may be 50 billion years away. In the future, the density of dark energy will remain the same, and the gravitational pull of all things in the universe will not be able to reverse the expansion of space, and the universe will expand infinitely. In the distant future, galaxies' gravitational pull will not be able to bind their structures, and dark energy will tear galaxies apart.

Next, structures like the solar system will also be torn apart, planets will be deorbited, and the universe will be filled with isolated celestial bodies. As space continues to expand at an accelerated pace, gravity is unable to sustain the structure of stars and planets, and these objects are torn apart into nebulae. Not only gravity, but also electromagnetic forces, weak nuclear forces, and strong nuclear forces, which are much stronger than gravity, cannot fight against dark energy.

At the last moment, even the atomic structure will be torn apart by dark energy.

The lifespan of the universe is endless. From the space of the universe, we can conclude that space has no edges.

The lifespan of the universe is incomprehensible to human beings, and after so many years of research, scientists have no way of knowing how people came to be. How can it be ** how long is the lifespan of the universe?

The lifespan of the universe is 140 billion years。At present, there is a well-established theory of the origin of the universe, which is that the universe originated about 13.8 billion years ago, and then began to expand and evolve. But there are many theoretical hypotheses about how the universe came to an end.

Scientists are struggling to find out how the universe will end.

A generalization of the universeThe universe is a general term for the vast expanse of space and the various celestial bodies that exist in it, as well as the diffuse matter. The origin of the universe is an extremely complex issue. The universe is the material world, which is in constant motion and development.

For thousands of years, scientists have been searching for when and how the universe came to be.

To this day, many scientists believe that the universe was formed by a big ** that occurred about 13.7 billion years ago. The matter and energy in the universe are gathered together, and condensed into a very small volume, the temperature is extremely high, the density is extremely high, and the huge pressure is generated in an instant, and then a large ** occurs, and the reaction principle of the big ** is called quantum physics by physicists.

The universe will die one day. The birth of the universe and the inevitable death of the universe have been a logical conclusion since Hubble discovered that galaxies were retreating and came to the conclusion that the universe was expanding. We now have a good idea of how the universe came to be, but how will it end?

Is it a big squeeze or a big fission? This is ultimately determined by its total weight. As far as research and observation are concerned, the weight of the universe is very close to the threshold of eternal expansion (Great Fission) and eventual collapse (Great Extrusion).

It remains to be seen and studied in which direction it will eventually develop and in what way it will end. But it is undeniable that it will die in one of two ways. There are independent universes and mass universes.

The independent universe belongs to the universe, while the mass universe belongs to all things.

<> to ask how long the universe will last, in the case of the mass universe, when the individual life of the mass ends, the universe also ends, because when a life ends, he does not know anything, the universe ends and disappears for him, and it does not matter to him no matter how the universe develops. This is life in the universe. The universe is a brain cell.

It doesn't know where it started, it doesn't know when it will end, and it never will end. The universe is eternal in time and nothing in life.

If you set a time for the universe to die, what would be the name of the eternity after that second? If the universe has one life, then it has death and it has life. What was the name of the universe before it was born?

If we give life to the universe, what if the universe goes on forever before and after? The Chinese have long said that the universe is infinite and boundless.

How can we measure it in terms of longevity? Life is meaningless to the universe, the universe will never disappear, but the internal changes are slightly smaller, the total mass will not be less, if the earth changes before, the total mass of water is still so much, what is the lie of the big **, if there is a star is a fireball, the sun is a fireball and it will not affect other stars. The sun is getting smaller and the other planets are getting bigger.

This means that the total mass of the universe is balanced. How much mass is converted into each other, and the result of heat energy also produces matter.

13.8 billion years ago, the universe produced a big **, because no one has been able to measure how much life the universe still has, and now it is only 4.6 billion years later, because there are no good tools to help us measure this time.

The lifespan of the universe should be billions of years, because no one knows how long the lifespan of the universe is, and the universe has been operating normally, and no one can be sure.

There is no way to tell, it should be at least many hundred million years, and the current universe is in the process of rapid expansion, so it should not disappear.

There should be many years, because there is no way to measure the lifespan of the universe, and the universe will never disappear, so the holding period is relatively long.

The universe is now close to 14 billion years old. This age is determined by measuring the Hubble constant, which is a means of expressing the rate at which the universe is expanding.

Most astrophysicists agree with the idea that the universe is expanding, so the answer to your question is ......

No, we can't calculate the lifespan of something that's still expanding. We can roughly calculate when our star, the Sun, will run out of fuel, i.e. 5 billion years from now, the Sun will enter the red giant phase. We know this because we have been observing and studying the sun for quite some time.

But for the universe, we hardly see the real picture, and whatever we see – we can't fully comprehend it.

As for how the universe will eventually be destroyed, these are some of the theories that claim to know the answer.

The Great Freeze- The Great Freeze is a scenario in which the continuous expansion causes the universe to asymptotically approach absolute zero temperature. It's going to be cold outside.

Great Rift- According to this theory, the density of dark energy increases over time. As a result, all material objects in the universe, starting with galaxies, eventually (in a limited time) all forms, no matter how small, will be torn apart into unconstrained elementary particles and radiation.

Big Crunc H - Just as the big ** began the expansion of the universe, the theory assumes that the average density of the universe is enough to stop expanding and begin to contract. In the end, we will leave a speck of dust behind.

Multiverse Theory - A multiverse hypothesis states that our universe is just one of the largest of an infinite number of simultaneously expanding largesse spread over an infinite distance.

Or things may just be beyond our imagination.

We still have to keep our eyes open and gaze there as much as possible to unlock the mysteries and secrets that our universe holds. It will take some time.

How old is the universe?

Astronomers estimate it to be 13 billion to 14 billion years.

Washington, April 24 (Xinhua) -- Astronomers said on April 24 that they used the "Hubble" space telescope to observe the oldest white dwarf star in the Milky Way discovered so far, which provides a new way to determine the age of the universe. The newly estimated age of the universe is about 13 billion to 14 billion years.

Astronomers told NASA's press conference that the ancient white dwarfs were discovered in a globular cluster called M4, located in the constellation Scorpio, 7,000 light-years from Earth. Analysis shows that these white dwarfs are about 12 billion to 13 billion years old.

White dwarfs are the products of the burn-out of early stars in the universe, and they gradually cool down with age, so they are considered the ideal "clock" to measure the age of the universe. Astronomers have metaphorically said that estimating the age of the universe with the help of white dwarfs is like using embers to guess when a charcoal fire will go out. But the problem is that white dwarfs get fainter and fainter due to constant cooling, which is a difficulty to overcome in actual observations.

In the process of observing the M4 globular cluster, the observation capabilities of the Hubble space telescope have been pushed to the limit. It took the telescope's camera eight days out of 67 days to capture the faintest and hottest white dwarf to date. These white dwarfs are extremely faint and less than 1 billionth as bright as the faintest stars the human eye can see.

Hello, in connection with the question you asked, how much of the total life span of the universe is the time that the universe has life, we can look at it from the history of the universe. The history of the universe can be divided into four stages: the birth of the universe, the development of the universe, the evolution of the universe, and the demise of the universe.

The birth of the universe occurred at the time of the big **, about 100 million years ago, the development of the universe refers to the distribution and structure of the universe matter, the evolution of the universe refers to the formation and change of the universe matter, and the demise of the universe refers to the disappearance of the universe matter.

The question of how much of the total life span of the universe is not good because the total life span of the universe is not known, but it is certain that the time of life in the universe is only a small fraction of the total life span of the universe. The time of life in the universe began about 100 million years ago after the big **, and until now, the time of life in the universe accounts for only a small part of the total life span of the universe, perhaps only a few percentage points.

No one knows how long the life span of the universe is, because the universe was about 13.8 billion years ago, when there was a prototype of the universe, and then gradually evolved, 13.8 billion years is very, very long for human beings, because the current life of the earth is only 4.6 billion years. Human life is only a few decades, and a hundred years is a relatively long time.

The life span of the universe may be billions of years or tens of billions of years, which is no problem, but the life span of the universe is not equal to the life span of the earth, and the life span of the earth is not equal to the time of human existence, because there is a big time difference, the universe has existed for years, the earth has existed for 4.6 billion years, and human beings have existed for only a few million years. Eventually they disappear, or rather, they develop well, and they disappear from our existing visual universe.

How long the life of the universe lasts depends on the shortcomings of the universe, that is, what will destroy the universe, which is a very puzzling question. Because human beings can enjoy how the earth will be destroyed, for example, when the earth is hit by other planets, the energy of the earth is too great, the earth can not withstand the solid disappearance, how will the star be destroyed, and finally the energy will disappear and gradually degenerate into brown dwarfs, but the universe is so big, how will it disappear? No one knows that it may require a higher level of life, or even a god-level civilization to exert a certain influence on the universe.

In fact, the life span of the universe is not a problem that human beings should be concerned about, human beings should be concerned about the life span of human civilization, not the life of the universe, the life of the universe is very long, but it is not equal to the time that human beings can exist, human beings are affected by viruses, bacteria, and changes in the natural environment, which may affect the time of human civilization.

It is estimated that life may exist in the universe for between 1,1000 and 1,100,000 of the total life span of the universe.

There are still 24 billion years of life in the universe. The universe could "live" for at least 24 billion years, which is longer than they originally expected. Scientists used observations from the Hubble telescope to calculate dark energy in the universe to come to this new conclusion.

The lifespan of the universe is 24 billion years. The analysis is carried out by spectroscopy and is also calculated by a Hubble constant.

The space we live in is infinitely expanding, and when it expands to the limit of the universe, there will be a great tear in the universe. In the very distant future, as the universe expands infinitely, the gravitational pull of galaxies in the universe will weaken accordingly, and at that time, dark energy will tear all galaxies apart. The solar system will also be torn apart.

The planets in the universe will gradually deorbit and become isolated objects, and astronomers speculate that the Great Tear is very likely to occur in 50 billion years. And that was also the time when the life of the universe ended.

The universe is composed of a body of time + a body of matter. The body of time is the body of space-time is the only one, and the body of matter is innumerable, but all of them are in the body of space-time. Therefore, the universe is also unique.

There are basically no large universes, no small universes, and there are no parallel universes and multiple or countless universes.

The universe has a beginning, and there is a beginning and an age. There are various theories about the age of the universe, some say 13.8 billion years, some say 18 billion years, and I don't think either of them is the true age of the universe. The true age of the universe should be much older, it is unknown.

What is the Universe? That is, in infinite space, the sum of all the countless planets that are moving naturally is called the natural universe in which we live today, and the universe is the sum of all the planets that are naturally moving in all the space, and so on! If we can tell how long the life span of the universe can be, if all the planets in the universe we live in today are completely destroyed by nature or man-made and are no longer in natural operation and operation, then the universe we live in can be regarded as the end of life!

If there is a planet in the universe where we live is functioning normally and is not destroyed, then the cosmic life we live in this beautiful universe will be immortal and immortal forever!

Use the method of counter-evidence to prove that time has no beginning and no end. Suppose that time has a source, then there is no matter before the source of time, according to the law of the immortality of matter, from the present to the present, there is still matter before the source of time, and since any matter has time, there was time before the source of time, which is consistent with the assumption that there is no source of time, thus proving that time has no source. Nothing can stop time from moving forward, proving that time has no beginning and no end.

What is the lifespan of the universe? The universe is composed of time body + matter body, time is eternal, and matter is immortal, which determines that the life span of the universe is also permanent and immortal. In other words, the life span of the universe has a beginning and no end, and it is infinitely eternal and eternal.
