What will happen if humans enter a star-level civilization?

At present, the civilization created by human beings is the only civilization in the solar system, but the civilization stage we are currently in is still very low. According to the classification of cosmic civilization by the astronomer Nikolai Cadal Shevsky of the former Soviet Union, we can't reach the first-class civilization, which is about 0.75. First-class civilization refers to the ability to master, utilize and arbitrarily transform the resources and energy of a planet. Secondary civilization refers to the resources and energy that can be mastered, utilized and transformed into a galaxy, while tertiary civilization refers to the resources and energy that can be mastered, utilized and transformed into a galaxy. Obviously, at present, we can't grasp, utilize and transform the earth's resources and energy at will, but we can only do some small-scale local construction and transformation, such as building reservoirs or canals and other water conservancy projects.

So today's human civilization is not even a first-class civilization. When we reach the first-class civilization, we will be able to master and use all the resources and energy on the earth, and we can transform our earth at will. However, the resources and energy of the earth are limited after all. When the human population reaches a certain scale and our scientific and technological capabilities reach a certain level, we will move towards the solar system. In other words, we need to become a second-class civilization and strive to master, utilize and transform the resources and energy of the solar system. The energy that secondary civilization can master is 65.438+000 billion times that of primary civilization, so when we become secondary civilization, we can use the resources of the whole solar system. So how will mankind develop the solar system?

I think it will mainly be reflected in the transformation and utilization of other planets, creating a habitable base for human alien immigrants. In the future, human beings will transform Mars, Venus, Titan, Ganymede, Europa, Mercury and even the moon one by one, and some planets will even be pulled into the livable zone of the solar system, artificially installing magnetic fields to retain the atmosphere and transforming it into an ecological environment similar to the earth's surface, so that human intervention can basically be carried out. Of course, to do this requires a lot of energy supply, so where does the energy come from? Perhaps many friends have thought of Dyson sphere, which is to make a light energy collection device around a star like the sun, just like a solar panel, because the sun is the largest energy center in the whole solar system!

If we can use its energy effectively, people in the future will not have to worry about energy problems. However, it is unlikely to realize dyson sphere in science, because there are many alternative ways of energy in the future, such as nuclear fusion energy, and there is no need to build a giant construction project with a diameter of several hundred million kilometers. Moreover, it will require huge material resources and basically has no possibility of realization.

However, humans can implement such projects on a small scale, such as building a huge solar energy collection network similar to satellites near the earth, and then trying to transmit this energy to the earth, which can basically solve most of the energy supply on the earth. If human beings want to transform the whole solar system, it is estimated that science and technology will take thousands of years to develop, but as long as human society can develop steadily, human beings will inevitably develop and transform the whole solar system in the future.
