"To sum up, the technology involved in this metal sphere is definitely a second-level civilization, and even far more than a second-level civilization, but I'm curious about why this thing hasn't produced intelligence since it is a second-level civilization" Leox muttered to himself with burning eyes."
What intelligence" Bai Hao's ears were sensitive, so he naturally heard his soft whisper, and couldn't help but ask with some doubts."
Bai Hao, do you know, I suspect that this metal ball is not a machine at all, or an alien's technological product, but a metal life, a real metal life" Leox looked at the metal ball with a complicated expression.Metal life, extremely rare, has not been encountered in the entire tens of millions of years of race history of the Yanshen Race, and has only been heard of.And the reason why he Leox knows about metal life is that during the long interstellar journey, he learned about this magical existence by chance.He couldn't figure out why he was here in Bai Hao, seeing this kind of legendary thing, "What is a metal life?"
Bai Hao wondered."
Metal life is a life form whose whole body is composed of metal elements and has soul consciousness.Just as all living things on Earth are carbon-based lifeforms.In the vast universe, there are countless life forms of all kinds, and no one knows how many life forms exist in this vast universe, but there is no doubt that there are many, many of them. ”Listening to Leox's words, Bai Hao was shocked, and the shock in his heart was indeed not small, although he had long known that aliens really existed, although he had heard that there was indeed extraterrestrial life, but he knew from Leox's mouth that there were all kinds of life forms in the universe, and even the strange life of metal life actually existed.Bai Hao was really shocked.Life composed of a pile of scrap iron, this is Bai Hao's view of metal life.When the poor earthlings are still arguing about whether there is life in the universe, there is a metal life in their hands, which has to be said to be a bit funny, human scientists have been exploring extraterrestrial life for a long time, but the results have been achieved in recent years.On July 7, 2003, NASA launched two planetary probes, Opportunity and Courage, and they were busy on Mars, and the whole world watched them, and every tiny step forward in them was exciting.On March 2, NASA announced that "Chance" had discovered water on Mars, a news that delighted scientists and amazed the public.In fact, the most important thing for human beings on earth is to find other creatures similar to themselves, and they seem to be very lonely.How likely is it that there are other life forms in the universe, astronomers have been working to find evidence of the existence of extraterrestrial microbes, and on Mars, Europa, the Moon, Venus, and everywhere in the solar system is the object of their search.But the most exciting progress in the exploration of extraterrestrial life in recent years has been done on Earth.Extraterrestrial biologists have traveled to the harshest and most extreme places on Earth, in the driest Atacama Desert in Chile, in the harshest caves, under the millennial ice shelves of Antarctica, under thousands of meters of deep sea, and at tens of thousands of meters in the sky.In the ancient frozen rocks of Antarctica, there is a bacterium that comfortably hides in the porous space beneath the surface of the stone, and lives as vigorously as the morning glory in the window of a flower shop; French scientists have discovered a variety of bacteria at the mouth of a hot vent at the bottom of the Pacific Ocean at a temperature of up to 250 degrees Celsius.The "Apollo 12" spacecraft, which landed on the moon in 1969, retrieved the camera left on the moon by the unmanned probe "Observer III" two and a half years ago, and found that there were microorganisms on the earth at the bottom of it, "Streptococcus paldyne", a microorganism from the earth, which survived on the surface of the moon in a vacuum and filled with cosmic rays for two and a half years.
Some bacteria survive by converting iron compounds and sulfur to maintain the continuation of life; Some bacteria thrive in boiling water; Some bacteria survive in salt water below 0C; Some bacteria survive at incredible high pressures.It seems that the life of most bacteria is never-ending, and the spores of some bacteria can be dormant for thousands of years.Their potential for life is completely or almost different from that of other life on Earth.It is this difference that suggests to us another possibility of life, perhaps another possibility of life on other planets in the universe.Since the bacteria on the earth show such a rich form of life, how many possibilities should life be in the universe Life on the earth is composed of nucleic acids and proteins, but is this the only form of life that exists, can there be other life that has developed based on other chemical bases Thinking of this, Bai Hao couldn't help but ask Leox with some curiosity: "Since there is even metal life in the universe, what form of life will exist, should there be stone life?"
Leox looked at Bai Hao and asked: "Your protein life on the earth is based on the element carbon, open your periodic table and see which element has the most similar properties to carbon, and after reading it, you will find that of course it is the silicon element in the same family."
And the stone life you are talking about is actually silicon-based life" "It's just that, unlike carbon-based life, silicon-based life doesn't need to ingest organic matter as an energy source for action, they only need to absorb the light energy of stars from the universe to sustain life, and the exhaust gas exhaled by your carbon-based life is carbon dioxide, so silicon-based life creatures exhale silica, a compound of silicon and oxygen.Silica is actually the sand we usually see on the beach, that is to say, silicon-based life spews out sand particles when it breathes" "So, all planets where silicon-based life exists are generally gravel planets, and deserts are all over the surface of the planet, and for other life forms, there is a forbidden area for life" "In addition to carbon-based life and silicon-based life, there are also sulfur-based life, amino life, these two kinds of life breathe sulfur and ammonia respectively when breathing, but the temperature of the planet where sulfur-based life lives is extremely high, and sulfur is in the air, It's just in the form of gas" "As for amino life, it's actually the closest life form to you earthlings," Leox said to Bai Hao with a smile."
The closest to the earth" Bai Hao's spirit was shocked, and he wondered: "Where are they" "In your solar system, in addition to the four rocky planets closest to the sun, Mercury, Venus, Earth, and Mars, there are four atmospheric planets of Jupiter, Saturn, Uranus, and Neptune, and on Jupiter, the largest of the eight planets, there is amino life.Because Jupiter is a cold giant gas planet, below its surface, there is a vast ocean of liquid ammonia, and the ocean is full of life forms with ammonia as the medium, that is, amino life is just this amino life, just ordinary life, not even wisdom" "In addition to these forms of life, of course, there are many, many more, such as oxygen-based life, fluorinated silicone organisms, hydrogen-based life, nitrogen-based life, etc., countless, just one earth, there are such brilliant life forms, And in the wider cosmic sea, life is even more abundant. ”"Of course, life forms and intelligent life are not the same concept, although there are many planets in the universe where life forms exist, but there are only a handful of planets that can truly evolve intelligent life.From this point of view, the higher intelligent life in the universe is even rarer. ”"Do you know that your earth has been formed for so many years, and even evolved intelligent life, but few aliens have descended on the earth" Leox smiled: "It's because there are too few intelligent lives near your solar system, and the alien civilizations that have developed advanced civilizations are even more pitiful, and even in the entire Nuoda galaxy, there are few decent advanced civilizations" "So, the galaxy is a large area of virgin land that has not yet been developed, and most of the planets and resources in it do not have their owners, As for who can become their masters in the end, it depends on the performance of you earthlings" Bai Hao swallowed his saliva and said with difficulty: "Is there really no advanced civilization in the entire galaxy" How big is the galaxy is to describe it as boundless The galaxy is the galaxy where the solar system is located, including 1000 to 400 billion stars and a large number of star clusters, nebulae, as well as various types of interstellar gas and interstellar dust.It has a diameter of about 100,000 light-years and a center thickness of about 12,000 light-years, which means that it takes at least 100,000 years for light to fly from one end of the galaxy to the other, which shows how big the galaxy is.And in such a vast galaxy, there are not a few decent advanced civilizations, Bai Hao absolutely does not believe it."
Although there are not a few decent advanced civilizations, there are indeed many planets with a higher level of civilization than your earth, but if they don't enter the stream, they don't know how many years after they find the earth" Leox smiled: "After all, the galaxy is located in a remote part of the universe, and there are few resources, so it's not a very strange thing that it can't develop a higher civilization" "If you have to say, the most strange thing about the galaxy to me is you" "I" Bai Hao pointed to himself."
