I used space to carry a lot of supplies to escape famine in ancient times

Over the course of the earth's history, human society has continued to develop and evolve, the population has grown like a snowball, and the demand for resources has become increasingly huge, and Mother Earth is gradually overwhelmed. The gradual depletion of resources, the deterioration of the environment, and the increasingly cramped living space are like the sword of Damocles hanging over the heads of mankind, constantly threatening the future of mankind.

Against this grim backdrop, world leaders and scientific elites gathered together for an emergency meeting concerning the fate of mankind. The atmosphere in the conference room was solemn, and everyone's eyes were focused on the large screen in front of them, which displayed the various crisis data currently facing the earth.

"Ladies and gentlemen, the situation we are facing now is extremely critical." The UN Secretary-General's face was serious and his voice was low and powerful. "The explosive growth of population and the over-consumption of resources have brought the earth's ecosystem to the brink of collapse. We must find a new way out as soon as possible, otherwise the future of mankind will be in jeopardy."

The participants nodded one after another, their faces full of worry and heaviness. At this time, a famous scientist stood up, pushed his glasses on the bridge of his nose, and his eyes revealed determination and hope.

"Our top priority right now is to develop a practical interstellar migration plan. The universe is vast and boundless, and I believe there must be new planets suitable for human habitation. We must gather global forces and make every effort to find and develop these new living spaces."

His words were like a stone thrown into a calm lake, stirring up a thousand waves. The conference room immediately erupted in heated discussions, with people expressing their opinions and suggestions one after another.

After several days of intense discussion and in-depth research, the interstellar immigration plan took shape. In this major plan related to the future of mankind, Gu Qianning and Chu Mohan were entrusted with the task of promoting the plan in an all-round way, relying on their rich experience and outstanding abilities in the field of exploration.

Gu Qianning and Chu Mohan knew that they had a great responsibility, so they immediately threw themselves into the work. First, they set about forming an interdisciplinary professional team, which included top talents in astronomy, physics, biology, engineering and other fields. The team members gathered in a spacious and bright office, with galaxy maps and various scientific data charts hanging on the surrounding walls.

"Hello everyone, we are now facing an unprecedented challenge, but also an opportunity full of hope." Gu Qianning stood at the front of the conference room, looking at the team members with a firm gaze, "Our mission is to find a new planet suitable for human habitation and develop a detailed plan for interstellar immigration. This requires the efforts and wisdom of each of us. Let us work together to fight for the future of mankind."

Chu Mohan went on to say, "We need to start from multiple aspects. Astronomical observation equipment will conduct a comprehensive scan of the galaxies in the universe to find areas where Earth-like planets may exist. Physicists and engineers will study the technology of interstellar navigation to ensure that we can reach the target planet safely and quickly. Biologists will evaluate the ecological environment of the new planet to see if it is suitable for human survival and reproduction."

Team members nodded one after another, indicating that they understood their responsibilities and tasks, and then all work was carried out in an orderly manner.

The astronomy team stayed in front of the huge astronomical telescope day and night, carefully observing every corner of the universe. By analyzing the spectra of stars, brightness changes, and planetary transits, they screened out a number of galaxies that may have Earth-like planets.

"Look, this star in this galaxy has a planet orbiting within the habitable zone," said a young astronomer, pointing excitedly at the data on the screen.

"Great, we need to focus on this planet. Collect more information about it, such as its size, mass, atmospheric composition, etc." The team leader immediately gave the order.

At the same time, physicists and engineers are also working hard on interstellar travel technology. They are trying to develop new energy drive systems to increase the speed and endurance of aircraft. Chu Mohan personally participated in this project. He discussed various technical solutions with team members and continuously conducted experiments and improvements.

"We can consider using antimatter energy. It has an extremely high energy density. If it can be successfully applied, it will greatly shorten the time of interstellar travel." Chu Mohan put forward a bold idea.

"But antimatter is very difficult to obtain and store, and we need to overcome many technical difficulties," said an engineer worriedly.

"It's okay, let's take it step by step. Let's conduct theoretical research and simulation experiments first to see if it is feasible." Chu Mohan encouraged everyone.

Biologists are also busy. They study organisms in various extreme environments in the laboratory, trying to understand the adaptability of life under different conditions. They also work with geologists to analyze the formation and evolution of different ecosystems on Earth to provide reference for evaluating the ecological environment of the new planet.

"We need to consider the impact of multiple factors on life, such as the new planet's gravity, atmospheric composition, temperature, and water resources," said the biologist team leader. "Only when these conditions meet certain requirements will it be suitable for human habitation."

With the joint efforts of the team members, the interstellar immigration plan has gradually made some progress. They have discovered several potentially habitable planets and have a preliminary understanding of the basic conditions of the habitable planets. However, to determine whether these planets are truly suitable for human habitation, more in-depth exploration and research are needed.

Gu Qianning and Chu Mohan decided to send unmanned probes to these planets. The probes were equipped with various advanced scientific instruments, which could conduct detailed analysis of the planets' atmosphere, soil, water quality, etc., and take high-definition photos and transmit them back to Earth.

After a long wait, the probes finally arrived at their target planets one after another. When the first batch of data and photos were transmitted back to Earth, the entire team gathered around the display screen nervously.

"This planet looks promising. It has an atmosphere and large blue areas on its surface, which may be water," a scientist said excitedly.

However, as they analyzed more data, they also found some problems. The planet has a slightly greater gravity than Earth, a lower oxygen content in the atmosphere, and some unknown microorganisms.

"These issues require further research and solutions," said Gu Qianning. "We cannot be blindly optimistic and must comprehensively assess the impact of each factor on human survival."

As a result, the team members conducted in-depth discussions and research on these issues. They proposed various solutions, such as genetic modification to adapt humans to the gravity environment of the new planet, developing new oxygen production equipment to increase the oxygen content in the atmosphere, and conducting detailed research on unknown microorganisms to ensure that they are harmless to humans.
