Only when mankind enters the era of science and technology can we understand how powerful science and technology is. You know, during the five thousand years of human civilization, there has been basically no great progress, and it has been in the era of cold weapons, let alone exploring the mysteries of the world and the universe.
Only after mankind entered the era of science and technology, it took us only a few hundred years to achieve brilliant scientific and technological achievements. It can be said that this development speed is amazing, and no one would have thought that we would have such brilliant technology in just a few hundred years. At this time, many people also saw endless hope. As long as our technology continues to develop, it seems not impossible to surpass or even dominate the universe in the future.
Of course, it is still too far away for human beings to travel around and dominate the universe. Many people will think of such a question: if human science and technology develop so fast, what brilliant achievements will we achieve if we are given hundreds of years of development time? How powerful is human civilization after 300 years?
You know, 300 years ago, mankind just stepped into the road of scientific and technological development. At that time, it was the age of steam engine, just out of the manual age. If we can go back to 300 years ago and compare the technology of that era with today's technology, you will find that it is completely the gap between heaven and earth. If it is not after entering the era of science and technology, the development time of 300 years will not be much improved for human civilization.
However, when mankind enters the road of scientific and technological development, there will be obvious scientific and technological progress and changes every year. Hundreds of years is a short time for the whole history of human civilization, but for a scientific and technological civilization, earth-shaking changes will take place. If a modern person can travel through time and space to the future hundreds of years later, you will also feel that Granny Liu has entered the Grand View Garden.
At that time, you will also find that modern science and technology are worlds apart, and there is no comparability at all. So what great changes will happen to human science and technology in a few hundred years? Speaking of the rapid development of science and technology, we must first talk about energy, which is the core of scientific and technological development. The speed of energy development directly determines the development speed of a science and technology.
In the hundreds of years when mankind entered the era of science and technology, the main energy used was fossil energy, such as coal, oil and natural gas. , including combustible ice, a relatively clean energy source, is still a fossil energy source. Fossil energy makes human science and technology develop rapidly, but it also brings constant damage to the earth's ecology, which is a major side effect of fossil energy.
Hawking also predicted that if human beings rely on fossil energy to continue to develop for hundreds of years, the earth's ecology may collapse completely and the earth will no longer be suitable for human survival. So what is the probability of such a thing happening? In fact, the probability of occurrence is not great. You know, human beings have been working hard on energy exploration.
It is impossible for human science and technology to achieve another leap by relying on fossil energy. Scientists also say that human beings have developed the potential of fossil energy to the extreme. Moreover, fossil energy is not inexhaustible, and these resources on the earth cannot maintain the long-term continuous use of human beings. Therefore, in the future, it is inevitable that more powerful new energy will replace fossil energy.
So what will be the more powerful energy for the next generation of mankind? Someone may have thought of it, and it was controlled nuclear fusion. As we all know, stars rely on internal nuclear fusion reaction to provide huge energy radiation, which is a very powerful energy, far exceeding fossil energy. More importantly, the raw material of fossil energy is the most common hydrogen in the universe.
Nuclear fusion energy is also a very clean energy, which will not produce various environmental pollution like fossil energy. Once the controlled nuclear fusion is realized in the future, fossil energy will withdraw from the historical stage and human civilization will enter the era of nuclear fusion. Some people may say that controlled nuclear fusion is not so easy to appear.
Yes, the realization of controlled nuclear fusion technology is really difficult. Scientists began research and exploration as early as half a century ago, but the progress is still slow. Although there are many difficulties to overcome in the realization, scientists also believe that the realization of controlled nuclear fusion will not be in the foreseeable future. Ideally, it will be realized in another 50 years. Even if the progress is slower, the controlled nuclear fusion technology will basically be realized in 100.
Once the controlled nuclear fusion is realized, it will enter a brand-new era for both the earth's ecology and human development. By then, the deterioration of the earth's ecology will stop, and human beings will rely on other technologies to distort the earth's ecological environment step by step. Hundreds of years later, the earth will once again become a beautiful life planet.
When we master the nuclear fusion technology, the space age will really come. By then, the spacecraft will enter space without rocket boost, but it can easily get in and out of the earth like a normal plane taking off and landing. At the same time, the speed of the spacecraft, with the blessing of nuclear fusion power, may achieve a preliminary sub-light speed flight.
With the primary sub-light speed flight, the solar system has become our back garden, and we can easily travel to every corner of the solar system. We can also go out of the solar system and explore some nearby galaxies. It is possible that by then we will find extraterrestrial life and even extraterrestrial civilization.
Hundreds of years later, human civilization is not only the era of nuclear fusion, but also the era of artificial intelligence. I believe many people know that the development speed of artificial intelligence in recent years is illegal and fast, and we can also predict that artificial intelligence will become a trend in the future. With the rapid development of artificial intelligence, after hundreds of years of human civilization, most of the work will be done by artificial intelligence, and people's daily life is also inseparable from artificial intelligence. Whether it is laundry, cooking, housework or other daily applications, it may be replaced by artificial intelligence. Artificial intelligence will become a very important and indispensable auxiliary partner for human beings.
Of course, in addition to the above, there will be many other changes in human civilization hundreds of years later. Although it will be very difficult and inaccurate for us to predict where human civilization will develop after thousands of years and tens of thousands of years, if we want to predict human civilization after hundreds of years, we still have to predict a lot in advance.
Of course, the road of scientific and technological development of human civilization is still full of many unknowns. Although we expect the future of mankind to be better, we will be able to roam the universe and explore the distant starry sky in a few hundred years, but there may still be some unexpected and unknown events that interfere with human development in a few hundred years, such as the invasion of alien civilization and asteroid impact.
