Humanity in the universe. Isn t it going to get old?

No one can give you the right answer to this point.

People who don't grow old are actually constantly leaving you.

If you can reach or exceed the speed of light in the universe, time will pass slowly in geometric proportions.

Time is the order of material movement, human beings in the universe, still have to metabolize, as long as they live and have thinking, they will inevitably grow old!

Human beings originally lived in the universe, but the earth as a medium, if there is no such medium, that is to say, when gravity is lost, the load on the human body will be minimized, and the metabolism of the human body will slow down, but it does not mean that it will stop, so it will be old, but it is relatively slow, and the metabolism of the new cycle of the human body will not change due to the change of human speed, but only due to the load of the human body!

People grow old in space.

Because weightlessness in space only slows down the aging process of human beings, but there is still an aging process, but slowly, so it is said that people will still grow old in space. Although it will slow down aging, it will still return to its normal aging rate when it returns to Earth.

According to Einstein's theory of relativity.

It is said that human aging is related to the speed of movement, and the closer to the speed of light, the slower the aging speed, if you take a spaceship in the universe.

Long-term operation will delay aging, as for the space station, it depends on its state, it should be the earth's space station.

It won't be moving at high speed, so the space station should be about as far away as people on Earth.

Related experiments

NASA conducted a related experiment. Scottrade is the International Space Station.

of one of the astronauts.

He took part in NASA's twin experiments, for which he needed to spend a year on the International Space Station.

But scientists accidentally discovered that Scott's white blood cells.

Telomeres unexpectedly lengthened, which meant that Scotter had reverse growth in space and slowed down aging, but he returned to Earth at a normal rate of aging.

As for the topic of whether human beings will live forever in the universe, I believe that human beings are a biological species, and they are the ecological embodiment of the stages of biological species, just a passer-by of the times, and no species can survive forever, and only the birth and continuation of epochal life will exist forever in the universe.

Why? Because, on the one hand, the formation of biological species is a phased form embodiment, with the passage of time, the phenomenon of variants and variants will evolve, and any species has an evolutionary process of formation and extinction, which is a passing guest of the times.

Natural disasters, viruses, genetic evolutionary limits, contradictions, and so on, species (humans) will disappear one day, and they are the laws of ecological development that cannot survive forever. On the other hand, although a species cannot live in the universe forever, as the universe continues to advance in time, life at different stages is randomly born and continued.

The soul after death should be a kind of consciousness.

And consciousness is an energy. Just like light, it's just that current technology can't detect the wavelengths of energy that release consciousness. Light can carry information, and consciousness can also carry this basic personality information, or a kind of trait information, which is easy to understand, but it should be noted that the same personality does not mean that it is the same person.

I think consciousness is like a driver, it's a foundation. It's like writing a very awesome AI**, but put it into the body of a 386 computer, because of the structure, it may only start to execute simple commands (low-level creatures), or even fail to execute; But if you put it in the galaxy computer, you can give full play to the full ability of this **, and it may also produce the concept of "self".

can exist with the time of the universe, that is to say, life that is born and survive in stages can survive with the time of the universe, in other words, life can live forever in the universe. I wonder if this answer is accurate?

No, because human beings live on the earth, and once the earth's energy consumption is gone, human beings will not be able to survive and will disappear.

Yes. Because human beings have advanced intelligence, and human beings will continue to develop their technological level, human beings will live forever in the universe.

Personally, I think so, because with our current technological development, the universe will definitely develop better, so as to achieve a longer existence.

These are the ripples of space-time caused by Einstein's theory of relativity. It took decades for scientists to develop instruments sensitive enough to detect gravitational wave signals from colliding black holes, an example of how detecting anything depends on advances in technology. So, in terms of technical characteristics, it ,.. with the advancement of our technology

We may suddenly find many signals from the activity of technological civilization. Loeb is broadly optimistic about these results.

<> we humans may not be that special, there are so many planets in the universe, and the rise of civilization may not be so rare. Astronomers say we should try to develop search techniques and strategies now so that we can see more. It remains to be seen whether we are special in the universe.

What do you expect humans to find? Humans have been talking about life all the time, especially in extraterrestrial civilizations. People are becoming more and more curious about them, so they are constantly being explored.

The universe is so big that anything can exist, but proof is needed to prove its existence.

Evidence of extraterrestrial civilizations may be found in the future, but so far no evidence has been found to support their existence. One scientist says that while extraterrestrial civilizations exist, they don't last long. But their technology will still be there, so why would they discover the ruins of a civilization that did not exist before?

Extraterrestrial civilizations have some technical features that our spacecraft cannot detect, and these are too small to exist on exoplanets. Therefore, the technical characteristics of these layers cannot be observed indirectly.

Discovering new features of civilization requires advanced technology, and these advances cannot be achieved in a short period of time. Some scientists can spend decades building a high-tech detector, but discovering more about the universe requires our advanced science. So, what else can we discover in our current exploration of the universe?

Are we special in the universe?

Human beings are too good in the universe at the right time, in the right place. The distance between the Earth and the Sun is not far or near. Just enough to receive the sun's heat.

And there is not a lot of heat, which is very suitable for human survival. And human beings are now the only intelligent life forms in the universe for the time being. None of the other planets can be used for life.

It is relatively unusual, human beings have been exploring a lot of knowledge in the universe and promoting the development of cosmic civilization, so the existence of human beings is unusual.

It's very unique, living in the middle of the earth, creating a lot of unexpected realms, and it's very peculiar.

It's weird, my career is on the side of the earth, and I have created a lot of unexpected situations, and it's very unique.

The universe was born 15 billion years ago, laying the material foundation for the creation of the earth. The Earth as a planet originated from the primordial solar nebula 4.6 billion years ago. Since then, the Earth system has evolved from simple to complex, and the evolution of its components is both interconnected and mutually influential.

The movement of the earth system and the resulting geomorphological changes, life phenomena and life activities together constitute the history of the earth. In the nearly 4.6 billion years of the earth's history, human civilization is less than 10,000 years, and the history is only recorded for 5,000 years. It's really a long way to bury the earth.

And human development is only 10,000 years ago, a few billion years ago, a billion years ago, hundreds of millions of years ago. What happened in those hundreds of millions of years in between? Could it be that in these hundreds of millions of years, there will be quite a powerful advanced civilization that has developed, grown, ruled the earth, and then perished?

It's just that the fossils haven't been found yet. What humans know about the Earth is just a drizzle. Is there a prehistoric civilization in the end?

I think there should be, but whether the civilization at that time would be more advanced than it is now, it must be impossible. Because if there is a higher civilization than the current one, no matter what happens, it is impossible to leave no trace at all.

There are definitely prehistoric advanced civilizations. 4.6 billion years old brother, does there must be a fossil in an advanced civilization? Advanced civilization may not be based on the existence of our human body as a cell to dig 4.6 billion years to do a long process, it is very likely that the earth will appear civilization, destruction, civilization, and other processes, the earth's resources have been reorganized many times, the earth's resources are different, the biological species are different, the way of human civilization is different, the history of human beings within 10,000 years is measurable, the history of 100 million years is not examinable, the process of civilization is accelerated, and after 10,000 years, our human beings will exhaust the earth's resources, destroy the ecological environment, and lose civilization, and it is another crustal movement. The production of a new ecological environment, the rebirth of civilization, the ecological environment produced by the movement of the earth's crust determines social civilization, grasslands, forests raise animals, iron ore builds high-rise buildings, Silicon Valley produces semiconductors, enters the electronic society, oil feeds cars, uranium produces nuclear **, so the earth's resources determine social civilization.

I'm coming to you! First of all, according to scientific measurements, the age of the universe is about 13.7 billion years, which is not only its age (time), but also its spatial length. Our universe was created about 13.7 billion years ago.

And this is the beginning of everything in the universe, including time. The speed of light is the fastest speed in the universe. So the distance we might observe is only 13.7 billion light-years!

This distance is called the "horizon". The most perfect unity of time and space, that point (or moment) is the beginning of our entire universe.

Second, this measurement was calculated by scientists based on the redshift phenomenon and the Hubble formula.

The landlord has encountered a situation where a police car or an ambulance siren is blaring past you on Mazhihu Road. The sound waves emitted towards the object that is moving towards you are compressed, so that the sound is higher; The sound waves of objects that are moving away from you are stretched, so that the pitch is lower. Based on the sound waves, you can determine how far and near the vehicle is close to you.

This is the Doppler effect. Doppler redshift is the same thing. In 1929, the American astronomer Hubble established that the redshift of galaxies was proportional to their distance from us (now known as Hubble's Law) by comparing redshift and apparent brightness.

The 12 billion light-years mentioned by the landlord are determined according to Hubble's law.

Hope it helps!

On the issue of human population. In the past, people were busy with life, pretending, and producing. Didn't think about it.

Through the emergence of the epidemic. Only then did I begin to realize that human beings were just the result of biological evolution. And not evolution.

Humans are also one of the many animals.

After the advent of mankind. The special hall is noisy for nearly a hundred years. It's really growing fast.

From the 19th century onwards. It's almost a 100 million a year. Now it's 7 billion.

But beware. Not all of these 7 billion can be worked. The aging of the population is severe.

The carrying capacity of the earth is limited.

Now scientists have begun to think about the Moon and Mars. And that's not even talking about the galaxy and the universe. There is still a lot of room for development.

As for a thousand years later. That's something we can't imagine. No scientist could have foreseen it yet. What happens.

Speaking of the universe. That's too big. How many galaxies does the universe contain? How many solar systems are included in the Milky Way? The Ground Plexus Ball is just one planet in the solar system. Doesn't explain anything. He cannot represent the development of the entire universe.

There are also aliens in the universe who can live for hundreds of millions of years, because many alien civilizations, we can't understand at all, or science and technology are not developed enough to reach the height of friendship with them.

Because it takes time for light to propagate, humans use the magnification factor of a telescope to estimate time.

It's the universe 12 billion light-years away, not 12 billion years ago.

Weightlessness in space slows down the aging process of human beings. The reason is that there is no gravitational acceleration that exists on Earth in space, and in a space environment without gravitational acceleration, people do not need so many calories and can greatly reduce their food intake.

According to Einstein's theory of relativity, human aging is related to the speed of movement The closer to the speed of light, the slower the aging speed, if you take a spaceship in the universe for a long time, it will delay aging, as for the space station, it depends on its state, it should be that the earth's space station will not be moving at high speed, so the space station should be about the same as people on the earth.

Astronauts will not be affected by the vacuum, because the spacesuit can definitely protect the astronaut, if the quality of the spacesuit is slightly worse, the astronaut will be dangerous, not only can not breathe, but more importantly, the blood pressure will burst the whole person.

There is no gravitational acceleration that exists on Earth in space, and in the space environment without gravitational acceleration, people don't need so many calories and can greatly reduce their food intake.

Reduced food intake means a slowdown in the rate of metabolism, and the slower the metabolism of any organism, the longer its growth period. In weightlessness, the mass of the body's muscles decreases and the heart rate slows down, reducing the burden on the heart. As a result, the wear and tear of the body's organs is also reduced.
