How do interstellar immigrants move?

Millions of years ago, due to the lack of resources and climate change, human ancestors migrated from the African continent to the whole world, ushered in a more vigorous human population development. Now, marine pollution, global warming and population expansion make us face the same problem again. In this context, interstellar migration has been put on the agenda.

It is the dream of many scientists for nearly half a century to change human beings from a race on earth to an interstellar race (a race that spreads to the universe). However, when we were still struggling for the cause of immigration, an accident made another creature on the earth successfully complete the "interstellar migration" and possibly survive on the moon, that is, the water bear worm.

As we all know, the water bear worm is a simple, petite and slow-moving eight-legged slow-moving animal. Because it often appears in wet moss, it is also called moss pig. 1773 was discovered by scientists under the microscope, with a body length of about1mm. Because its shape is similar to that of a big bear and its body structure is very obvious, it is named after a water bear.

Water bear insects are widely distributed, and they are likely to live in your flowerpot and high temperature pit. In the past hundred years, water bear insects have been gradually known to us for their super survival ability and adaptability.

Interstellar migration should be the cutting-edge technology pursued by human beings. Why did the water bear worm arrive first? This is due to a moon landing accident and a man.

Nova Spivack is an entrepreneur who loves the space industry very much. He is very worried that mankind will face an unknown catastrophe in the future, which will lead to the extinction of mankind. Therefore, in 20 15, he set up a "human civilization reserve plan" for a rainy day, intending to send some human civilization and earth biological genes into space and store them on the moon. The water bear worm with strong survivability naturally became the first choice to be sent into space.

1April 9 1 1 day, this plan was undertaken and implemented by Israel. However, the ideal is beautiful, but the reality is very skinny. This spaceship named Genesis crashed when it landed on the moon, and thousands of water bear insects were scattered on the surface of the moon.

If these water bear insects didn't die in the plane crash, then they probably completed the "interstellar migration" that we humans envy. In an interview, Nova Spivack said, "According to the crash height of the spacecraft, the water bear worm has a great chance of survival."

Many people are puzzled by this. Even if the water bear worm is not killed in the impact, there are still low temperature, lack of oxygen, lack of water, radiation and high temperature on the moon, and they will still kill the water bear worm. But is this really the case? We don't have an answer, but let's not forget how strong the water bear worm is.

First of all, water bear insects are resistant to low temperature and high temperature. According to the Huffington Post, in 20 16, Japanese scientists successfully resurrected the water bear worm that had been frozen for 30 years. These water bear worms were discovered in Antarctica in 1983, and then scientists kept them frozen for 20 16 years.

In addition, German scientists also found that the water bear worm can survive for several days in the environment of 18 1 degree Celsius and MINUS 272 degrees Celsius, which shows that it is entirely possible for the water bear worm to adapt to extreme cold and heat.

Followed by lack of water and oxygen. Scientists say that before being sent to the moon, these water bear insects were in a state of "suspended animation" due to lack of water and stopped all metabolism. They can keep this state 10- 120 years. Isn't it horrible?

As for hypoxia, it is not a problem. According to research, they can survive for 5 days without oxygen.

Finally, talk about their radiation resistance. In 2007, with the help of the European Space Agency, a group of water bear insects successfully entered space and stayed in vacuum and radiation environment for 10 days. Although only one tenth of the water bear worms survived in the end, it shows that they have certain radiation resistance.

According to the available data, their resistance to X-ray radiation is 100 times that of human beings.

Although from various conditions, they may not live on the moon for long, at least they have completed the "interstellar migration", and they were all wrapped in epoxy resin before landing on the moon, which gave them another layer of protection. It's hard to say whether they are still alive now.

However, one thing is certain. If they want to be like the earth, it is impossible for the time being. After all, the water bear worm is a kind of heterotrophs, and it can't wake up and expand its population without water and food. They can only hide quietly in the "escape capsule" like in science fiction movies, waiting for rescue one day in the future.

Unless they can evolve the ability to adapt to the lunar environment, it is a bit difficult to evolve because they can't reproduce. For how long these water bear worms can live, an American biologist once said, "They may live on the moon for several years."

It is quite a long time to survive for several years, which can be regarded as a successful "interstellar migration" and the first earth creature to complete the "interstellar migration".

As for why water bears have such strong viability, there is a report in the journal Nature Communication that a Dsup protein in water bears may be the main reason why they can resist radiation. We don't have a particularly good explanation for other abilities.

In any case, the first person to complete the title of "interstellar migration" obviously belongs to the water bear worm.

On the other hand, at present, human beings have neither a strong physique like a water bear nor a superb technology like a "three-person". Before the interstellar migration, we should still take good care of our earth.
