Will humans become interstellar species? Among the many science fiction films we have watched, the future of mankind seems to be that many people will travel in the vast universe and even migrate to the human base of various planets . Even in reality, tech tycoon Musk's SpaceX company has proposed the exciting Mars immigration plan . NASA in the United States also proposed a plan to establish a lunar base. Last year, the second shopkeeper also shared that China is also planning a plan for the large-scale space station and related research plans. From these points of view, humans are very interested in interstellar immigration to and becoming an interstellar species.

Why are we keen on interstellar immigration? What kind of "big filter" mechanism should be faced with interstellar species? Why is the key energy development and replacement crucial? The second shopkeeper of will learn about it separately with you. Remember to talk about your views after reading it.
Speaking of interstellar immigration, let’s first think about the motivation. The first thing that comes to mind may be the need for survival, the rapid development of human civilization, and human scientists have various debates about the future judgment, but there is great consistency in the existence of the earth’s environmental crisis. Many scientists even believe that it may be an unimaginable species crisis.
Human scientists have also argued about the future, but there is great consistency in the existence of the Earth's environmental crisis
After all, research on the history of the earth has proved that species on Earth have experienced several mass extinctions in billions of years, and dinosaurs in museums also seem to tell us that even strong can't withstand an environmental catastrophe from the earth. The dinosaurs in the museum also seem to tell us that even strong can't withstand an environmental catastrophe from the earth.
But in fact, the dangers that scientists are worried about are human self-destruction , human destruction to nature, the climate crisis caused by the emission of carbon dioxide , and the threat of super weapons, seem to be more dangerous than the Earth's regular species extinction crisis.
Jonathan Jiang from NASA's Jet Propulsion Laboratory said in a live science article. "We are our own big filter," In fact, as a species we already have the ability to self-destruct and we have not even cracked the first level of the Kardashev scale. A few countries now have enough nuclear weapons to destroy every person on the planet.

The Kardashev scale mentioned here was proposed by Soviet astronomer Nikolai Kardashev in 1964. attributes the level of human civilization to the level of energy utilization. As mentioned in the video of the second shopkeeper before, we have not reached the first level of civilization, that is, we can use all the energy of the planet.
Let's focus on the large filter mechanism, which explains why we have not found evidence of advanced alien civilizations based on the dangers brought about by increasing energy utilization. If the earth is not extremely special and life and wisdom development are not very special, then Milky Way should be full of intelligent life. This assumption sounds a bit like Fermi Paradox , and the following is different, and it is even an explanation of the Fermi Paradox.
2's shopkeeper mentioned in the video that we have not reached a first-level civilization, that is, we can use all the energy of the planet we are located in.
If this assumption is true, although human civilization has not existed for a long time, from an astronomical perspective, the Milky Way has a history of billions of years, and there should be other intelligent life. On a certain planet, it has developed to become an interstellar species and explore the level of immigration to various planets.
But the fact is that we humans are still lonely, and we still have not discovered other intelligent life outside the earth.
Then there is such a theory, there is a large filter mechanism, Perhaps before civilization develops into higher civilization, some mechanisms will erase this intelligent life on his planet . Either it is not an environmental crisis caused by carbon dioxide, or it is not a threat to super weapons such as nuclear bomb , or other dangers caused by the smart civilization's out of control in the process of using energy.

Of course, these theories are not necessarily the future of human beings. This is just a theory proposed by people for not discovering the current situation of alien civilization and human development.
But Jiang and his team explored the best ways to achieve Class I state in a paper by arXiv , and in their research, they built a model in which they followed the recommendations of the UN Framework Convention on Climate Change, which clarified the consequences of the continued unabated use of fossil fuels. Unless humans quickly turn their energy supply to nuclear and renewable energy, we will cause too much damage to our biosphere to continue upgrading the level of civilization.
In a paper on arXiv, the best pathways to reach the Class I state and possible time points were explored, in their research, in building a model
The model they constructed also assumed that renewable energy and nuclear energy use increased by 2.5% per year, and found that these energy usage forms will steadily replace fossil fuels over the next 20 to 30 years. It is also believed that nuclear and renewable energy have the potential to continue to increase production without putting further pressure on the biosphere, and If we continue to consume at the current rate of energy, we will reach a Class I civilization by 2371.
Do you think humans will upgrade to a first-level civilization, pass through the large filter mechanism, become an interstellar species, and preserve the fire of humans?
Finally, they also pointed out that there are many assumptions in this model, and the uncertainty may be around 100 years, including the assumption that we will determine a safe way to deal with nuclear waste and that improving the ability to utilize energy will not lead to disasters.
