Fairy tales of emigrating to other planets

1. It is actually an impossible task for human beings to emigrate to other planets.

I am glad to answer for the landlord.

It is entirely possible for human beings to emigrate to other planets. We humans will definitely check this planet before choosing a good one. What are the disadvantages? We humans can try to avoid it. We don't need to transform the whole planet at once. We can transform it bit by bit. Moreover, when we can emigrate to another planet, we will not shrink back because of the environment of that planet. At that time, we humans will definitely think about it before making plans.

thank you

2. Title If you are a pioneer in moving to another planet and can only take one creature from the earth, which one do you choose?

If you want me, I'll smoke a cigarette first, because there is only one kind, and one day counts.

3. If human beings want to emigrate to other planets, what problems should be solved first?

When people successfully entered the universe, they really saw the real situation of the universe for the first time. At the same time, they also found that the resources on the earth were consumed too quickly and had to find a second planet suitable for human habitation in the universe. If humans want to migrate to other planets, many people will discuss what problems should be solved first. What we need to solve is the problem of adapting to the new environment and spacecraft. Let's analyze it.

But I think the most difficult thing is to transport it to a new planet. We couldn't go for no reason in the past, but we still had to carry some technology, otherwise we couldn't guarantee the safety of people in the past. There are too many unknown factors in the universe. There is nothing wrong with the sentence "The known is not the most terrible, but the most terrible is the unknown". Many unknown factors in the universe are likely to be fatal once they occur. Maybe these planets have their own civilization, but we just don't know it.

If you want to move to another planet, humans may choose Mars as the first choice to move to another planet. Why?

First, because its size is not much different from that of the earth, the gravity of Mars is not much different from that of the earth.

Second, it is because the distance between the earth and the sun is similar to that of the earth. We don't want Mercury and Venus to get too close to the sun, and the surface temperature reaches more than 400 degrees during the day, unlike Saturn and Jupiter, which are too far away from the sun.

Third, because Mars also has an atmosphere, but its composition is different from that of the Earth.

Fourth, it is found that the water on Mars flows very fast, and scientists speculate that solid water can be found in the valleys of Mars.

Although these factors cannot be the conditions for a second earth, they are quite satisfactory compared with other known planets. If we really want to survive on Mars, human technology must make a qualitative leap.

5. Who has a movie about human migration to another planet? Urgent need!

return to earth

Return to Earth describes that a famous general Saif Richie (played by will smith will smith) and his son Katy Richie (played by jaden smith jaden smith) were forced to land on the unrecognizable earth 1000 years after catastrophic events forced humans to flee. When the general is seriously injured, Katie Ritchie must step into a completely unfamiliar danger and send out a distress signal, and also face the serious threat of all kinds of terrible creatures that have evolved on earth and fierce alien monsters that escaped unexpectedly because of plane crashes. In order to survive, father and son must learn to work together, trust each other and try to find their way home on the dangerous earth. Finally, Katie Richie successfully sought help.

7. When can humans migrate to other planets?

Moving to another planet is a long-cherished dream of mankind. Stephen Hawking, a famous physicist, recently accepted the Copley Medal awarded by the Royal Society, saying that human beings must emigrate to other planets in order to get rid of the fate of extinction. Hawking believes that as long as human beings are trapped on a unique planet, their long-term survival is in danger. Threats such as asteroid impact on the earth and nuclear war will destroy us sooner or later. However, if we expand into space and build self-sufficient settlements, our future should be secure. There is no place like the earth in the solar system, so we must find another planet and use more advanced space rockets to help people move to a planet suitable for survival. This is the second time in six months that he has made such amazing remarks.

Griffin, director of the National Aeronautics and Space Administration (NASA), also said that historically, species on a single planet cannot survive forever. "We have conclusive evidence that, on average, every 30 million years, species on earth will suffer mass destruction; One day we will definitely immigrate to another planet, but I don't know when that day will be. "

There are four criteria for migration destination.

What difficulties need to be overcome in emigrating to another planet, and when will it be realized? The first level of immigration: where to migrate. At the beginning of the 20th century, some people thought that Mars and Venus might be good choices, but NASA soon found that other planets around the sun were not suitable for us to live in. People on the surface of Venus must live at a temperature high enough to melt lead. As for Mars, living on it is like living twice as high as Mount Everest.

Dr. Margaret Tenbar, an astronomer at the Carnegie Institute in Washington, DC, summed up four criteria of "the most suitable galaxy for life": 1, at least 3 billion years, enough to form planets and show complex life; 2. The volume of the central star should not exceed 1.5 times that of the sun, otherwise it is difficult to produce planets suitable for life; 3. There should be enough iron to form Earth-like planets; The central star should be neither a red giant nor a white dwarf, so that the complex life on the surrounding planets can exist for a long time. According to this standard, he concluded that there are five galaxies in the universe that meet the standard: one is CVn, the dog constellation 26 light years away from the earth; The second is HD10307; , 42 light years away from the earth; 3. HD 2 1 14 15, and its metal content is about half that of the sun; The fourth is Scorpio SCO18; ; Fifth, Pegasus 5 1.

Level 2: How do humans get to these planets? According to calculation, Alpha Centauri, the closest star to the Earth, is about 4.23 light years. At the current speed of the space shuttle, it will take 158000 years to arrive. This requires the vehicle to reach the speed of light. The American sci-fi movie Star Trek is set in the background that in the middle of the 20th century, engineer Koklen invented the "warp drive" which can fly faster than light. Because "warp speed technology" is the threshold to enter the galactic civilization family, human beings have been accepted into the interstellar Federation, and the level of civilization has reached a new level. In fact, scientists are moving towards this goal. According to New Scientist magazine, the US Air Force and NASA are currently secretly studying a "hyperspace engine". Scientists expect to make a prototype of "Hyperspace Engine" and test it within five years. Once the "hyperspace engine" is proved to be feasible, it only takes three hours to get from the earth to Mars, and it takes 80 days to get from the earth to the planet with a distance of 1 1 light-year. Some scientists predict that the time to actually manufacture a suitable spacecraft and fly to the destination planet will be in the 26th century, and the estimated arrival time is 65,438 years.

The third level: how to solve the problem of life support after human beings arrive at the planet. The United States, Russia and other countries have cultivated peas, wheat, corn, rice, onions, orchids and other plants 100, and animals such as fruit flies, spiders and fish can also grow and reproduce in weightlessness. If this technology can be applied to the future planet, the problem of human survival will be solved.

However, it is also a question whether human beings can reproduce after living in weightlessness for a long time. A French scientist found that under weightlessness, the important structure of living cells can't be formed normally, which means that human beings can't survive and reproduce in near weightlessness for a long time. However, some scientists say that after human beings settle on another planet, the race and body structure will also change with the environment, and perhaps the problem of reproduction can be completed in another way.

return to earth

Moving to other planets seems hopeless, but can we change our minds? Dr. O 'Neill of Princeton University believes that the best way is to build a space city in space and gradually move all human beings to the space city. After hundreds or even thousands of years of recovery, the earth will become a group of animals, the weather will become stable, and human beings can return to the earth without human intervention.

O 'Neill's Space City consists of a pair of cylinders. The inner wall of the Space City has a natural environment suitable for the growth of plants. There are roads, residential areas, commercial areas, work areas, etc. At one end of the space city is a solar power station, and at the other end is a hatch for the space shuttle or spacecraft to park.

8. The necessary conditions for the migration of life on Earth to other planets are as follows

Water is the condition for life on earth. Why do extraterrestrial life need water? It's like a CCTV program

I feel that mankind has entered a dead end, that is, water is a necessary condition for the existence of life.

Water may be at least the standard of the earth, but other living things don't necessarily need water to survive.

9. Why did humans choose Mars as the first stop to emigrate to another planet?

Because Mars is the only planet in the solar system that can barely sustain life.

10. Movies about human migration to aliens

A classic movie about human migration to another planet;

Deep space amnesia

The film tells the story of a group of astronauts who gave up their spacecraft and woke up with no memory at all. It is described as a combination of aliens and solar catastrophe, and at the same time it combines the bloody elements of life and death in a closed space. This sci-fi horror film with different styles and mysterious colors set off a sci-fi craze in the autumn of 2009. //ke。 /view/228492 1
