In a way, the situation on the planet Pandora and the fantasy world is not much different.

A civilization that is at a stage of disadvantage in development is targeted by a civilization that is at a higher level of development.

Although it is not a national regular army that appears on the planet Pandora, but only the mining department of an interstellar company, it can be seen from the technical level shown in the movie that the level of human civilization behind the mining company is not trivial.

Antimatter energy technology, cryonics technology, spaceship lightsail technology, as well as their power armor, shuttles, and more.

Based on previous research, the Star Empire has hypothesized a hierarchical model of different stages of development of cosmic civilization based on the level and total amount of energy that civilization can grasp and utilize.

The technology mastered by the RDA company is enough to make a judgment on their home civilization, which is a high-level first-level civilization that has entered the interstellar world and is moving towards a second-level civilization.

The first-level cosmic civilization can also be called the home star civilization, which has the ability to mine and utilize almost all the energy and energy on the home planet, that is to say, the civilization is the absolute "master" of the home planet, and can control the weather, land, and various natural phenomena on the planet at will, know the structural changes and rise and fall of the planet above and below the ground, and even have the ability to destroy the surrounding planets.

Generally speaking, it means that the first-level civilization has "supreme" capabilities on the planet where it is located, and the level of science and technology is at least the point of gene technology and nanotechnology, and the universal application of nuclear fusion energy.

The second-level civilization is called a planetary system civilization, and the solar system is a planetary system, which refers to the collection of various celestial bodies orbiting a star, including planets, moons, asteroids, meteoroids, comets, and cosmic dust.

The civilization has reached the point where it can leave its planet at will and exploit the energy of the stars near its planet.

The entire star system is under control, and you can habit, shuttle and develop energy on all the planets of the star system as you like, and you can build a Dyson sphere to make full use of the energy of the star.

If the first-level cosmic civilization or the current human civilization discovers and observes that an unnatural spherical structure has been established around a star, it means that there is really a civilization collecting stellar energy, which proves that the second-level cosmic civilization really exists.

It should be mentioned that if a civilization reaches the second level, then it is almost indestructible within the same level.

At least all the natural and man-made means that the Star Empire now knows can't touch a single hair of them.

Even a supernova explosion near them would not allow them to perish.

They can move their galaxy away from the erupting star, or simply harness the energy of the eruption. In a highly developed society, they themselves do not make self-destructive moves.

The Star Empire has not yet found a civilization that has reached the second level, and if it does, it may be the first thing to run away as soon as possible, as far as it can run.

The gap between the total amount of energy and the level of science and technology between the first-level and second-level civilizations is too great, and the first-level civilization can be said to have no chance of winning against the second-level civilization.

The swarm civilization and the chaotic forces from the subspace that have been encountered in the fantasy world before, the Imperial Research Department judges that they may be second-level civilizations in the universe or higher.

However, due to the limited contact with the other party, it is not possible to make an accurate judgment at this time.

Based on the first two level criteria, the third civilization level can barely be deduced, the stellar civilization.

The Milky Way is a galaxy, and a galaxy, or galaxy, is a collection of countless celestial bodies and stars that can emit light and heat themselves.

Therefore, the third-level cosmic civilization is also called the "galaxy civilization", the civilization can easily control the galaxy where it is located, and can also develop and use all the energy in the galaxy at will, and can even draw the energy needed for its own civilization from the existing black hole in the universe.

The way in which this civilization exists has greatly exceeded all the imagination of the current stellar civilizations, because the way this civilization exists is contrary to the cosmic theory of relativity.

A galaxy is very large, and the farthest distance between the two ends of the galaxy can range from hundreds of thousands of light-years to millions of light-years.

Therefore, the way of existence of the three-level cosmic civilization is unimaginable to human beings at present, and there must be scientific and technological means that transcend the barrier of the speed of light, wormholes or space channels, space curvature engines beyond the speed of light, etc., will be the most basic technologies, and even the emergence of cosmic laws and mathematical laws of weapons cannot be ruled out.

Due to the huge difference between the three levels of civilization, and the transition time for each level is very long, the cosmology researchers of the Star Empire are divided into three levels: high, medium and low according to their level of development.

According to current intelligence estimates, the human civilization behind the RDA is almost a high-level first-level cosmic civilization, and they have begun to climb to the second-level cosmic civilization.

In terms of development level, the Star Empire is currently also a cosmic civilization that has transitioned from the first level to the second level. However, because of the short development time, it may not be as advanced as the human civilization to which the RDA belongs in some aspects.

This is a cruel truth, which means that if Shen Sen decides to make contact with the planet Pandora, he will have to face a cosmic civilization that is not much different from the Star Empire.

Whether the two human civilizations met together would shake hands or break out into war, Shen Sen did not know, but he knew the various ways that could lead to the destruction of the cosmic civilization.

The development of civilization is not smooth sailing, and there is no way for a first-level civilization to disappear to reach a second-level civilization, let alone a weaker civilized world.

While the Star Empire gave the cosmic civilization level model, it also gave Shen Sen a reason for the possible demise of civilization in the development process.

For example, Level 0 civilizations will perish due to natural disasters, diseases, wars, and resource shortages.

The zero-to-one transition phase will fall due to extreme weather disasters, nuclear war, super geological activity, super volcanoes and earthquakes, and meteorite collisions.

Even if it successfully develops to the first level, there is a high probability that it will perish due to asteroid or comet collisions, artificial intelligence crises, drastic changes in solar activity, and imminent supernova explosions.

When it comes to the second-level civilization, it will not sit back and relax, because the demand for resources and the increase in the distance of activity will increase the probability of encountering civilizations, and when the two meet, it is very likely that an interstellar war will break out.

In addition, factors such as ultra-high-energy star explosions and galactic collisions have a chance to cause civilization to disappear.

According to the above possibilities, Shen Sen could not guarantee that the Star Empire would not be destroyed because of an interstellar war in the process of development.

Each civilization has its own needs to perpetuate, and when the two meet, any accident will lead to a war that affects the lives of tens of billions of creatures in both civilizations.

It's not a movie, it's a cold and cruel reality.
