What will your world be like in 50 years?

After many years, I walked into a wonderful world.

1957, an American astronaut predicted that it would take several generations for humans to land on the moon when the first artificial satellite of the former Soviet Union was launched, but his statement was overturned after 12 years. 1995, when bill gates painted a digital picture in the road to the future, many people felt incredible. However, when the expectation comes true, no one thinks it is unreasonable.

165438+ 10 15, the British magazine "new scientist" issued a "hero post" to more than 40 top scientists in various fields on the occasion of its 50th anniversary, inviting them to paint the future again. Let's follow their "brainstorming" and walk into the wonderful world after 50 years.

& gt& gt& gt Life Science

Organ renewal to routine

Robert Sinshmir, a scientist, predicted in 1957 that the development potential of genetic science was huge. He's right. Today, Bruce Rahn, a human geneticist at the University of Chicago, has drawn this blueprint more clearly. He said that by 2056, with the help of genetic technology, life forms on the earth will change, and organs for transplantation can be grown and cultivated from animals without waiting for donations from the dead, and unlimited supply will become possible.

And Ellen Haber Katz, a professor at the wistar Institute in Philadelphia, even predicted that the human body could realize self-renewal of some organs with the aid of regenerative medicine without transplantation. "Heart regeneration is in the near future, the regeneration of fingers and toes can be achieved within 5 years to 10 years, limb regeneration technology will appear in the next few years, and finally the damaged spine can be repaired. Within 50 years, the renewal of whole body organs will become routine. " By then, the quadriplegic can not only be cured, but also run a marathon. Even if you are not satisfied with a certain part of your body, you can "update" through this technology.

Human life expectancy has been extended by 40%

Not only that, but also the life span of human beings will be greatly extended. Richard miller, a professor at the University of Michigan in the United States, predicted: "It is now a routine technology in the laboratory to extend the life span of mammals by 40%. By 2056, this enhanced body protection system will be applied to human beings. By then, centenarians will be as energetic and energetic as people in their 60s. "

The childbearing age of women has been extended by 10 years.

Carl djerassi, a professor at Stanford University who is known as the "father of artificial contraceptives", believes that human reproductive technology and population reproduction will continue to change in the next 50 years. He predicted that women can store the extracted ovarian tissue or egg cells when they are young, so that the reproductive age can be extended by 10 years or even longer.

In addition, scientists hope to make a breakthrough in understanding sexual life and sexual health. Beverley whipple, Secretary-General of the World Health Association, said that she hoped that sexual health would become a universal human right in 50 years. "Sexual violence and abuse will be eradicated, sexual health education will be popularized, and diseases spread through sexual behavior will be curbed."

Computer self-renewal

Any technology and tool is an extension of the human body, and the appearance and development of computers make this extension infinite. Scientists also predict that within 50 years, human beings will invent intelligent robots with excellent performance, which can distinguish and classify objects as accurately as a two-year-old baby. They can also evolve and update themselves and deal with the outside world independently, instead of having to accept instructions from the outside world to complete their actions as they do now.

Interpreting animal language

Daniel Pauli, a professor at the University of British Columbia, believes that in 50 years, human beings will have the ability to communicate with animals, just like the protagonist in the movie Dr. Doolittle. "I think the biggest progress will be the emergence of a device that can detect, explain and convey animal emotions and their thoughts. In this way, people can be aroused. The equipment will be used first for primates, then for various mammals, and then for vertebrates, including fish. This will make people reject the eating habit of eating meat. Maybe, in the end, we may all become vegetarians. "

& gt& gt& gt Cosmic astronomy

Earth exploration ET

The discovery of aliens (ET) will be the greatest progress of human science and technology. Professor Freeman Dyson of the Institute for Advanced Life Studies at Princeton University said: "The biggest breakthrough in the next 50 years will be the discovery of extraterrestrial life. We are now stepping up the development of various tools to explore the more distant universe more effectively, and the development of optical tools, radio detection and data processing tools is also changing with each passing day. "

Chris McKay, a scientist at NASA, said that humans may find aliens on the earth. Mike Kay said, "In the next 50 years, we are likely to find alien life in the permafrost of Mars. Although it may be dead, its biochemical characteristics have been completely preserved. We may find alien life on the surface of Europa and even on Earth. "

Paul davis, an expert from Arizona State University, expressed the same view that alien creatures may have lived on the earth for millions of years. "Many lives exist in the form of microorganisms. It is difficult for people to tell which is life on earth and which is alien life just by appearance. If there are alien life on the earth, they will be identified. If we finally find that life on earth has different origins, we can prove that we are not alone in the universe. "

Immigrate to outer space

Some experts also predict that humans will find direct evidence of dark energy, which will help to uncover the mystery of the origin of the universe. It is possible for mankind to solve the mystery of the Big Bang 65.438+0.4 billion years ago. Sean Caroli, a theoretical physicist at the California Institute of Technology, said: "We can know for sure what happened in the second after BIGBANG, but all theories can't explain BIGBANG's moment. We have reason to expect this situation to change within 50 years. " Scientists also want to know whether the big bang that produced the universe is just one of a series of big explosions.

Richard Gott, an astrophysicist at Princeton University, predicts that with the gradual unveiling of the mysteries of the universe, mankind will take a tentative step on the road of emigrating to outer space. "Building a self-sufficient residence on Mars will provide a' life insurance policy' for mankind to cope with the catastrophe on earth."

In addition, scientists have many ideas about the future, such as inventing an inexhaustible green energy source. As the science fiction writer arthur clarke once said, "In the eyes of a backward era, there is no difference between modern science and magic." In fact, modern science has surpassed magic, and the slogan of the new era is: "Nothing is impossible except the unexpected!" "
