Why do people age fast in space

When flying in space, especially in deep space beyond the Lunar Space, the number one problem encountered is long-term weightlessness? Short term? Astronautical activities in near-Earth space will cause astronauts"Space motion sickness":

Dizzy? Sweating? Salivation?

Disgusting? Vomiting and so on? Of course, these symptoms usually go away after the astronauts return to the ground?

However, there is one problem that is difficult to solve, that is, can space flight cause osteoporosis? The human skeleton has long been adapted to the gravitational pull of the earth"Anti-Earth gravity"What are the functions? And once you enter the space environment of loss, these abilities are gone, and the muscles will begin to atrophy and the minerals in the bones will decrease?

Will too long a weightless time cause permanent damage to the bones, which can easily lead to fractures? In addition, a large loss of calcium can also exacerbate osteoporosis, causing irreversible consequences? Weightlessness also reduces the amount of hormones secreted by the pituitary gland, which greatly weakens the body's metabolism and immune function?

All of the above factors cause people to age, so people age faster in space than on Earth?

Who told you to age faster in space? Aging slows down in space, so ask NASA to make a twin to send a real-world example of spending a year in space.

When it comes to space, please open your mind and think seriously, what is time? (One revolution is one day, one revolution is one year).

If we put aside the rotation and revolution of the earth, there is no earth as a reference, and there is no sun as a reference, that is, there is no rotation and revolution, then I ask, what is the time we know?

If time is not established, without time, time does not exist at all?

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.

It won't last long. Living in space will have a certain effect of delaying aging, but it will not be immortal, which is unrealistic thinking. Man lives on earth.

Due to the influence of gravity, eventually there are aspects of the body that will be conditioned. Weightlessness in space will better delay human aging, but it will not live long.

No. Because the lifespan of human beings is controlled by genes, and the environment in space is not conducive to the survival of human beings, people will not live long in space for a long time.

Personally, I don't think people will live long if they live in space for a long time, because the conditions in space are not very good, and people will have a lot of physical health problems, which is a very bad living environment.

No, there is no clear scientific evidence for this, so it does not live long.

According to the theory of relativity, time is relative. This means that if you're flying in space, your clock will slow down, while the clock on Earth will run normally. This phenomenon is known as blindness before time dilation.

Therefore, people in space seem to age more slowly, while people on Earth seem to age faster.

This phenomenon is due to the effects of velocity and gravity, as these effects change the rate at which time passes. Traveling at high speed in space or approaching a gravitational field, time slows down, because time and space are interrelated, and high speed and gravitational guessing pull the fibers of time and space.

As a result, people in space will feel like time is passing more slowly than people on Earth. But that doesn't mean their biological age slows down. Their bodies will still age at the same rate, only their time seems slower relative to time on Earth.

When they return to Earth, though, they will actually be a little younger than their peers on Earth. This phenomenon is called twin paradox. Scientists have calculated that if one of the two people goes on a space flight and the other stays on Earth, there will be a difference of how many years in age between the two people.

In conclusion, even though people in space seem younger than people on Earth, their bodies will still age at the same rate. This phenomenon reveals the relative concept of time, and the amazing ability of physics to explain things.

Summary. People in space get old.

Although people in space will disturb the talk of getting old, weightlessness in space will also delay the aging process of human beings. The reason is that 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.

Summary. Qinqin is happy to answer for you: Do people get old in space, it will delay the aging process of human beings, the reason is that there is no gravitational acceleration that exists on Earth in space, and in the space environment without gravitational acceleration, people do not need so many calories, and they can greatly reduce their food intake, and reduced food intake means that the speed of metabolism slows down, and the slower the metabolism of any organism, the longer its growth period.

Qinqin is happy to answer for you: will people get old in space, is it will delay the aging process of human beings, the reason is that there is no gravitational acceleration on earth in space, and in the space environment without gravitational acceleration, people do not need so many calories, which can greatly reduce the intake of food banquet pants, and the reduction of food intake means that the speed of metabolism slows down, and the slower the metabolism of any organism, the longer its growth period.

Under the condition of weightlessness, the mass of human muscles will be reduced, and the rise of heart rate will also be slowed down, thereby reducing the burden on the heart as old as it ages. As a result, the wear and tear of the body's organs is also reduced.

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.

With the rapid development of the aerospace industry, many people must have a heart that is ready to move to an alien planet to experience it. Although outer space is mysterious and new, scientists have found that human spaceflight accelerates human aging. If that's the case, will humans still immigrate to alien planets?
