The second level of civilization is that they can make full use of the energy of their stars and completely control their solar system. You can live and travel freely on the planets in the solar system, and you don't have to worry about energy problemsBecause you know how to efficiently use the endless energy emitted from the stars, the society has become highly developed and the development tends to be highly accelerated.

It should be mentioned that if a civilization reaches the second type, then it is almost indestructible. At least all the natural and man-made means known to mankind cannot 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 will not make a self-destructive move.

Level 3 civilizations: are no longer limited to their solar system, but the entire galaxy in which they are located, such as our Milky Way. Harnesses the energy of all stars in the galaxy. This kind of civilization is beyond our imagination, and we can only guess how they lived. According to Einstein's theory of relativity, exceeding the speed of light is theoretically untenable. A galaxy is very large, and it takes millions of years to fly from one end to the other, even if it is close to the speed of light, so the third type of civilization is not like in science fiction movies, driving huge spaceships and shuttling through the stars.

Level 4 Civilizations: Speculate that they ingest dark matter and dark energy from the universe (both of which account for about 95% of the mass in the visible universe) as their energy source. As for the other aspects of such a civilization, it is impossible to conceive.

Ways of destruction of civilizations of all levels:

Type 0 → Natural disasters, disease, war, shortage of resources.

Type 0+ → Extreme weather disasters, nuclear war, super geological activity, super volcano and earthquake, meteorite collision.

Type 1 → Asteroid or comet collisions, artificial intelligence crises, upheavals in solar activity.

Type 1+ → Artificial intelligence rebels, the sun ages and expands and explodes, and is close to supernova eruptions.

Type 2 → Interstellar Warfare. Ultra-energetic star erupts.

Type 2+ → galaxy collides.

Type 3 → The Big Bang.

Type 3+ → Dissipation of consciousness.

(It is worth mentioning that the output power of each level of civilization is far more than limited to the electricity generated, but how much energy is used to maintain the activities of the civilization, for example, the type 1 civilization uses intelligent artificial clouds to reflect, cover or intersect the sunlight to control the earth's climate and weather, then the power of sunlight: 1000 watts and 1 square meter is one of the output power of civilization.) ）

With each level, the "total energy" of a civilization increases by a factor of 1,010, and the "mass" or "volume" of cosmic man-made objects increases by a factor of 1,010, and the "size" of man-made objects increases by a factor of 2,150.

Note: 21503 = 1010.

The ratio of the size (diameter) of man-made objects built in the universe by different levels of civilization:

Civilization Activity Output Power/s:

Civilization Type 1 = 1016 watts.

Civilization Type 2 = 1026 watts.

Civilization Type 3 = 1036 watts.

Total mass of cosmic man-made objects:

Civilization Type 1 = 10 million tons ; 1010 Kg。

Civilization Type 2 = 1 billion tonnes ;1020 kg.

Civilization Type 3 = 100 billion megatons; 1030 kg.

Total aggregate volume / size of cosmic man-made mass:

Civilization Type 1 = 107 cubic meters 0.215 cubic kilometers 0.215km × 0.215km × 0.215Km

Civilization Type 2 = 1017 cubic meters, 100 million cubic kilometers, 463 km x463 km, × 463 km

Civilization Type 3 = 1027 cubic meters 106Km × 106Km x 106Km

The Earth's human index is currently 0.72, which means:

The output power of a human being is approximately = 1013 × 1.259 × 1.259 = 1.6 × 1013 watts

At present, the cumulative total mass of man-made objects built by human Type 0.72 in the universe is about 10,000 tons, and the volume is several thousand cubic meters

These include satellites, probes, space stations, and laboratories in orbit.

Civilization 1's cosmic artifacts are tens of millions of square kilometers of space solar arrays, space cities/ports, interplanetary spacecraft, etc.

The cosmic artifacts of Civilization 2 are stellar collecting circles, artificial planets/rings, starships, etc.

The cosmic artifacts of Civilization 3 are galactic nucleus collecting circles, artificial celestial bodies, and even wormholes, intergalactic spaceships, etc.

Compared to those invisible futures, Hua Feng knew that there had been more historical civilization destruction events on the earth in the past......

The Bible says: "When Jehovah saw the great sin of man on earth, he declared that he would use a flood to destroy every living thing in the earth and every living thing that breathed flesh and blood on the earth, and that no one would die."

In Chinese legends, the cause of the great flood was a war between the water god Gonggong and Zhuan, and after the Gonggong was defeated by Zhuan, he was angry and broke the Buzhou Mountain, which supported the sky, so that the sky collapsed and the flood was monstrous.

And there is another legend in Jewish legend that "the Lord changed the position of the two stars."

In Babylon there is a prophecy that "when the planets converge in Scorpio and line up in a straight line through their orbits, all mankind on earth will be destroyed, and when the same gathering takes place in Capricorn, there will be another great flood on earth, the former in the middle of summer and the latter in the bitter winter." And the famous European prophet Nostradamus wrote to his family in 1555: "Before the destruction of the world, the raging tide will swallow everything." Lasting. And the few pieces of land that remain on the surface of the water will also be covered by flames and stones falling from the sky, and the beautiful world will be destroyed in one fell swoop!"

Nowadays, there are three main explanations, namely, the theory of external impact, the theory of earth volcanoes, and the theory of planetary changes.

Extraneous impact says: A huge asteroid hit the Pacific Ocean and caused tsunamis, earthquakes and other disasters, causing a major flood in the Northern Hemisphere.

Earth Volcano Theory: Earth volcanic eruptions caused a great flood.

Planetary change theory: the movement of the earth's axis causes changes in the north and south poles, the climate changes drastically, the original temperate zone becomes polar, the polar ice and snow melt, the sea level rises, and the atmosphere changes drastically in the whole process, forming super storms, thus forming a major flood.

The above explanations are all from the interior of the earth.

As researchers have come up with a new explanation, the tidal lock-in between planets caused the Great Flood on Earth.

But all of the above explanations for flooding are not convincing. The mystery of the unknown contained in the legend still needs to be answered.

Since most of the Flood legends are ethnic and appear many times, it may not be related to Christianity. Many Christians claim that the Great Flood was God's use to destroy the corrupt human race of the world. But not necessarily other peoples in the world have legends of the Great Flood. Therefore, some people believe that the Christian stringing together the legend of the Great Flood is nothing more than a kind of speculation and wishful thinking.

However, this peculiar phenomenon has aroused the interest of Christian-dominated geographers and historians, who are determined to find out the cause of the universality of this legend.

A more plausible case is that the global sea level rose by more than one metre 7,000-8,000 years ago. This sea level rise has flooded many nearshore and low-lying areas.

Of all the flood legends, the most well-known is the Bible in Genesis chapters 6 and 8. The Bible records that humanity's evil on earth has led to God's determination to destroy the world's civilization. God commanded the righteous Noah to build a giant ark and put at least one pair of every creature in the world into the ark.

The ark is 130 meters long, 22 meters wide and 13 meters high, and is divided into three levels, each with a small compartment spaced apart. Heavy rain fell from the sky, causing the water level to rise. The flood came and wiped out all the creatures on the earth, and only those in Noah's Ark were saved. So, after the water receded, Noah's family continued to live on a new piece of land. They became the ancestors of the peoples of the Middle East.

Sumerian Civilization –

The legend of the plains of Mesopotamia is very similar to the Bible. Before the story began, there was a heated debate among the gods of heaven about whether or not to destroy the world with a flood.

In Sumerian mythology, Enil, the god of wind and the king of the gods, found humans too noisy and sent floods, droughts, and pestilences to destroy them. However, the human race survived by the good-natured water god Enki, who taught Alahasis about irrigation, grain storage, and medicine.

Enil was quite angry and decided to secretly summon a few gods to send a huge flood to completely exterminate humanity, but Enki still knew about it and arranged for Utanapizm (Ut) in advance

apishtim) took refuge by boat, and later gave Utanapizm the ability to live forever, and told him to live in seclusion in the mountains. Ennier is furious and accuses Enki of obstructing his plan, and Enki explains to him that for the sake of the necessary balance, innocent humans should not be completely exterminated, and that the remaining humans should be sterilized. But, on the other hand, if humanity does not believe in the gods and falls, it can be slaughtered by the gods. This is the earliest version of the account of the Great Flood.

Mayan Civilization –

The Mayan Indians had a sacred text, the Bobovu Sutra, which they considered their lifeline, and it also contains an account of the flood in which the gods punished mankind in their wrath. It is said that the gods created humans at the beginning of the world, but this was a less successful experiment, and the gods first carved human figures out of wood and made them speak. These wooden men later lost their favor because they forgot the existence of the Creator. So the gods decided to launch a flood to destroy humanity......

Chinese Civilization:

Dayu controls the water——

In China, there is also a legend of Dayu controlling the water, telling that from the father of Dayu, he has begun to work on flood control. However, due to the ineffectiveness of his work, he was killed by Emperor Yao. When Emperor Shun took over, he asked Kun's son Yu to continue his father's work (there are two other versions: the legendary ancient emperor Zhurong was ordered by the Yellow Emperor to kill Yu's father Kun in Yushan; the other says that Kun was killed by Emperor Shun in Yushan). Due to the good results of this work, so that the people lived and worked in peace and contentment, Shun then Chan located in Yu and started the first dynasty in China: Xia (Yu's son Qi established the Xia Dynasty).
