The earth is so rich in resources, why should human beings risk their lives to go to space?

When human beings successfully entered space, they really realized that the earth was nothing more than this in space, and at the same time, they began to look for a second planet suitable for human habitation, and Mars was one of the goalsBut many people are very puzzled that the earth's resources are so abundant, why human beings risk their lives to go to space, in fact, because the consumption rate of many resources on the earth is too fast, we have to make this preparation, let's analyze it in detail.

There are indeed a lot of resources on the earth, especially marine resources to give us the conditions for survival, but pollution is also very scary, think about the current environment compared to a few decades ago, although high-rise buildings continue to rise, all kinds of buildings are getting better and better, transportation is more and more convenient, you can go out by bus, subway, car, etc., but the environment has not been there for decades, very simple examples will see fireflies before, but now it has long been seen, this is environmental pollution, Of course, these rapid developments mean that many of the earth's resources are being exploited.

The earth is indeed very rich in resources, but think about how much time the earth has existed, hundreds of millions of years have consumed a lot, plus the development is suitable for not caring about resources at all, large-scale development of resources are greatly and rapidly consumed, if you want to regenerate, the environment has been greatly damaged, simply put, the current environment wants to regenerate these resources are very difficult, and the resource consumption rate is very fast.

So we have to find a second earth in the universe, for the future of human beings to plan, resources this thing is like a short board effect, not depending on the longest board, but depending on the shortest piece, if the least resources are exhausted, other resources are irreplaceable, so the development of new resources is also very important, such as wind energy, hydropower, solar energy, etc., not only healthy and environmentally friendly but also very efficient, but the difficulty is still relatively large, so it is necessary to risk going to space, for the future of mankind.

Because space is very mysterious, human beings have an adventurous spirit, so they want to explore space.

Because the study of space is conducive to the sustainable development of mankind, it will be able to make better use of resources.

The growing population has overwhelmed the earth, and the sun is not eternal, and one day the sun will burn out, and it will be too late to think of a way out.

People will encounter various dangers when they leave the earth to go to space, so let's talk about several common dangers. Clause.

1. In space, suffocation due to the absence of oxygen. Clause.

Second, after going to space, because the spaceship lost control, people were forever floating in space and finally starved to death. Third, there are many rays in space, and people may be shot through the body by some rays in the universe in space, causing people to slowly suffer and die. Clause.

4. Humanity was torn to pieces by black holes in the universe. Fifth, it is very cold in space, so astronauts are easily exposed to space, resulting in being frozen to death.

First, in space, death by suffocation due to the absence of oxygen. We know that if human beings want to be able to live, they must have oxygen to provide to the human body, and when people leave the earth and go to space, because there is too little oxygen in the air, when we run out of oxygen cylinders, we will suffocate to death.

Second, after going to space, because the spaceship lost control, people were forever floating in space and finally starved to death. When we go to space, the spacecraft is empty, and we can't return to Earth to replenish food, in which case we'll end up starving.

Third, there are many rays in space, and people may be shot through the body by some rays in the universe in space, causing people to slowly suffer and die. There are all kinds of dangers in space, and many celestial bodies will also emit rays that are harmful to the human body, and when humans are unfortunately shot, the body's skills will slowly decay, and finally die in pain.

Fourth, humanity is torn to pieces by black holes in the universe or turned into "Northwest Ramen". When human beings go to space, they unfortunately encounter a black hole, and they will be swallowed by the black hole and affected by the gravitational force in the black hole, and will either be torn to pieces or turned into northwest ramen.

Fifth, it is very cold in space, so astronauts are easily exposed to space, resulting in being frozen to death. It's very cold in space, and if there's not enough to keep warm, it's easy for humans to get frozen into popsicles.

What dangers would humanity encounter in space if it left Earth? These points should not be overlooked!

When people leave Earth and go into space, they may encounter the risk of being infected with extraterrestrial viruses and bacteria, and secondly, they will encounter the danger of wandering black holes, which will be swallowed by terrible black holes.

Without gravity in space, humans experience weightlessness; There is no oxygen in space, and if there is not enough oxygen**, humans will suffocate; You may also encounter aliens and be bullied by them.

If you go to space, you may die without oxygen and lack of oxygen, or you may die because you encounter aliens. It can also be sucked into a black hole, which can also lead to death.

There are more than 20 dangers in space, such as being swallowed by a black hole, starving to death, being burned alive, freezing to death, being shot alive by radiation, and so on.

When people leave the earth and go to space, they may encounter the danger of space junk hitting them, they may lose their breath and die due to oxygen leakage, they may be hit by planets, or they may lose their gravitational attraction and float forever in space.

First: Death due to lack of oxygen. Second: After going to space, due to the loss of control of the spaceship, people floated forever in space, and finally starved to death.

There are terrifying gamma-ray bursts in the universe (which can scorch the earth in minutes); There are 1,000 black holes in the Milky Way galaxy alone, and black holes also move, and if a black hole comes close to the Earth, the Earth will be destroyed.

Imagination of the Earth scorched by gamma-ray bursts. ）

There are still many wandering stars and planets in the universe, and if they collide with the earth, the earth will suffer a great disaster!

An asteroid that hit the Earth 65 million years ago caused the extinction of the dinosaurs that dominated the Earth for hundreds of millions of years.

Some stars fly away from the Milky Way at high speed to wander).

The universe is very big and dangerous, the earth is a speck of dust floating in the universe with an uncertain future, and human beings are insects living in the dust.

The earth is very dangerous in the universe, and the human beings who have relied on the earth for survival so far are even more vulnerable, and they cannot survive without the protection of the earth.

Cassini flew to the vicinity of Tuxin and looked back at Earth, which is a faint blue dot in the universe).

But are humans a bunch of cooperative, intelligent bugs that can create civilization? Although the universe is dangerous, human beings cannot avoid danger in the universe, and since they cannot escape, they must face it bravely.

Humans walked out of Africa 200,000 years ago, and now humans have spread all over the earth, and there are still some lives in the sky).

Here are the top five reasons why humans explore the universe:

First, human beings are planetary nomads, if we look at human beings in a period of 10,000 years, human development will definitely exhaust the resources on the earth, for the future and long-term prosperity of human beings, human beings need more living space, human beings are the nomads of the universe.

Second, there is a gene of curiosity in human genes, and it is curiosity that makes human beings move from ignorance to civilization; The endless curiosity about the unknown leads to endless human exploration. Why explore space? Because space is in the **, waiting for humans to decipher.

Third, if human beings want to survive and reproduce forever, they cannot live forever in the swaddling clothes of the earth, because the earth and the solar system are to be destroyed.

Humanity needs to colonize the moon and colonize Mars. Colonize other star systems and leave a backup for humanity.

Fourth, as human beings become stronger and more in need of a more affluent life, more and more resources are needed to satisfy human beings' endless desires.

There are countless planets in the universe that are resources for human beings.

Fifth, the earth is a spaceship in the universe, and although civilization has been produced on the earth, in order for civilization to develop rapidly and become strong, it needs to communicate with other civilizations.

Humanity needs to find aliens, allies or enemies of civilization.

Sixth, in order to prevent human beings from destroying the earth due to infighting, human beings also need to go out of the earth and fly into space!

We believe that when people step out of our planet, they will leave their ethnic divisions behind. -- John F. Kennedy, Speech of February 21, 1962

Have you ever discovered that since the beginning of human civilization, we have been studying and exploring space, but the underwater world that is within our reach has rarely been explored, and why is that?

Is it far more important for scientists to explore space than the underwater world?

Actually, no, both the seabed and space are important directions for human exploration, but wanting to explore the underwater world is far from being as simple as we think.

Exploration The study of the deep sea world is actually of great significance to human beings, the deep sea occupies the entire volume of the earth, every year scientists discover new life species in the deep sea, and there are very large natural resources in the deep sea.

In fact, human beings have long been aware of the importance of exploring the deep sea, but the current science and technology are very limited in the study of the deep sea.

At present, human research on space can be said to be very smooth and successful, and the veil of space has been unveiled step by step. In the face of the deep ocean right before our eyes, more than 80% of it is still untouched by humans.

In addition to the technical difficulties, the main reasons for human exploration of the underwater world are the fear of the seabed, low visibility, unpredictable water temperatures, high pressure, corrosive deep sea, and anoxic environment.

At present, most of the land resources of the earth are still used by human beings, and it is believed that one day human beings will gradually unveil the veil of the deep sea of the ocean.

So far, human beings have not discovered any other intelligent beings, that is, extraterrestrial civilizations, therefore, it seems that people look up at the starry sky, starry, but there is no trace of life, as if the huge universe is only human, small and lonely. Human beings have been exploring space all the time, wanting to discover the existence of life, and there really is a higher level of life than humans.

In ancient times, people believed that the heavens were round, and the heavens and the earth themselves were split by a special person or god in the chaos, and gradually people realized that the earth was round, and the sun, moon and stars revolve around the earth, which is the famous geocentric theory; Later, Copernicus discovered that the earth revolves around the sun and established the heliocentric theory; Later, it was discovered that the Sun was nothing more than an ordinary star, and then the Milky Way and the large-scale structure of the universe were discovered.

Therefore, even if the Proxima Centauri system has a civilization similar to or inferior to humans, we have no way of knowing. According to the current level of human science and technology, if we want to observe evidence of the existence of extraterrestrial civilization, this civilization must at least reach the level of second-level civilization in the universe, that is, it can control the star of this level and change the appearance of the star, so that human beings can be aware. Human beings have been exploring space all the time, wanting to discover the existence of life, and there really is a higher level of life than humans.

In fact, scientists have calculated that although the cosmic civilization may be universal, there will not be too many galaxies, that is, the distance between civilizations may be very far, at least more than 10,000 light-years, that is to say, the light and electromagnetic waves there are emitted now, and it will take 10,000 years before we can see and receive them. Some scientists believe that it is very likely that only one civilization exists in a galaxy, so that even if there are trillions of civilizations in the entire observable universe, the chance of civilizations knowing each other and meeting each other is very slim.

Human beings have been exploring space all the time, wanting to discover the existence of life, there is really a higher life than humans, and human civilization is likely to be just a wave in the long river of the universe, which I think is very long, but compared with the time of the universe, it will be extinguished in an instant. Therefore, it is likely that until the demise of human civilization, it will be difficult to find extraterrestrial civilizations, which is the so-called bosom friend is hard to find.

I think there should be, but we're still exploring it.

Possibly, because the universe is infinite, there will be many unknown creatures in it, and there is no way to know for sure.

In fact, scientists have been worried about the problem of resources for many years, because decades ago it was said that oil and coal will be gradually depleted after more than 100 years or three or four hundred years, and there will be an energy crisis, but people continue to discover new mineral resources and new energy technologies, such as solar and nuclear energy, which are basically renewable and very efficientIt can inject a boost into our civilization, but when it will be popularized on a large scale depends on our technology.
