Is it possible for human beings to deduce their respective lifespans from the universe?

We know that human beings are made of atoms, and the density of black holes (possibly other universes) that scientists are talking about is a density slightly larger than the nucleus of an atom, so we humans, including all things, are countless small universes. However, particles of different masses have different decay speeds, so the time for an atom to lose all its energy and the boundless universe are simply incomparable, so at present, we still cannot use people and things to solve the mystery of the universe.

It has been said that the human body is a small universe.

Obviously, there is still a big difference between the human body and the universe.

Unfortunately, it has not been confirmed, so the whole hypothesis of the question is not valid.

We all know that stars have lifespans. Most stars have a lifespan of between 1 billion and 10 billion years, and the more massive the star, the shorter the lifespan. Since stars have lifespans, do planets also have lifespans?

How long do they live? In fact, the lifespan of the planet is infinite and can be as long as the universe. The lifespan of a star is unlimited.

1. There are no special circumstances, such as collisions with other planetsAs long as the universe exists, planets can survive. We all know that planets revolve around stars, and stars have lifespans, ranging from 1 billion to 10 billion years. So the star dies, that is, it becomes a white dwarf, a neutron star, or a black hole.

Since planets orbit stars around the world, and stars die, what happens to the planets that orbit it when a star dies? In fact, even if a star dies, the planets orbiting it will not be threatened with any death.

When a star dies and becomes another celestial body, then the planet adjusts its orbit and then orbits the remnants of that star; When a star disappears because of a supernova**, the planet becomes a wandering rogue planet in the universe. As for the meaning of the rogue planet, if you are interested, you can take a closer look at the most terrifying planet in the universe.

2. Planets are celestial bodies that orbit stars and do not emit light on their own. In general, the planet must be more than 800 kilometers in diameter, have a mass of more than 500 million tons, and have no larger objects in its orbit. So, the planets in the solar system that meet the above conditions are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The more massive the star, the hotter its interior and the more active it will be. So the larger the area of nuclear fusion inside the star, the faster the fusion speed will be. For example, if a star can fuse at a depth of 100,000 kilometers below the surface, then a star with a diameter of 200,000 kilometers will fuse at its core; A star with a diameter of 300,000 km.

3. Nuclear fusion can occur in the most central region with a diameter of 100,000 kilometers; A star with a diameter of 3 million kilometers can have an area of 2.8 million kilometers inside that can undergo nuclear fusion. Therefore, the greater the mass of a star, the shorter its lifespan.

The life span of a planet is infinite, and as long as it does not collide with other planets, the planet can exist forever.

The lifespan is infinitely long, and it can have the same lifespan as the universe, and there are no special circumstances, and there will be no danger.

The Earth is similar to the planets, and it may or may not be longer than the planets. Some speculate that the Earth is now 3.5 billion light-years away

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 hail of the universe will travel 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 earth's energy is too large, the earth can't withstand the solid disappearance, how will the star be destroyed, and eventually the energy will disappear and gradually degenerate into a brown dwarf, 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.

Of course, time starts from the universe, and the continuous time from the beginning of the singularity to the present is the age of the universe, which may be what you call lifespan. Recently, NASA released the "infancy" of the universe photographed by the probe, which provides a new basis for the theory of the universe. Based on these, scientists have also accurately measured the actual age of the universe to be 13.7 billion years.

If you're a cosmic lover, these pictures are a bit useful to you, don't forget to give a good review, hee-hee.

According to the current scientists, the universe has the end of its life one day, and there are two views, one is the theory of the collapse of the universe and the other is the theory of the cooling of the universe. The collapse theory states that the end of the universe will collapse again to a cardinal point under the action of gravity. I don't agree with it, but I prefer the cosmic cooling theory.

Because this one sounds more realistic. The universe is lit up by the light of stars, and the stars shine because of the continuous nuclear fusion reaction of hydrogen, but although there are many hydrogen elements in the universe, I have not heard of how to regenerate, so the hydrogen elements in the universe will be exhausted sooner or later, so that there will be no luminous bodies in the universe, so the whole universe will be completely cooled and lose its vitality, I think this may be the end of the universe. As for how long it will take, I don't want to know, and my descendants and I definitely don't have to worry about it, hehe.

The universe we live in has gone through 20 billion years, and it has reached its middle age, and the life span of the universe is still 24 billion years, but there will be many, many universes outside our universe.

Do people have a lifespan? Yes, but it can also be said that there is none, and it can be passed down from generation to generation. I think that the universe, like human beings, has no lifespan.

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.

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.
