"Mr. Zheng, these samples were just obtained from the water layer under the dry ice layer in the South Pole of Mars."
"Okay~"
"Test the sample immediately."
Zheng Yuan's heart was full of expectations.
Along with the scientific research on Mars, the understanding of Mars is getting deeper and deeper.
Liquid water was actually found at the bottom of the dry ice layer at the South and North Pole of Mars, because the dry ice layer is thick enough, followed by a thick layer of ice, which plays a very good role in insulation, and there is actually liquid at the bottom.
The presence of water.
This makes scientists extremely excited.
Because in such an environment, it is very likely that life exists in liquid water.
Therefore, Zheng Yuan personally ordered that he must find a way to get some samples.
"Yes~"
Soon, as the researchers placed the samples under the microscope, a large number of microorganisms appeared in everyone's sight.
"There really is life!"
Some scientists shouted excitedly on the spot, looking at these microorganisms carefully, they found that there were quite a lot of them, and the types were quite complete.
"It's incredible that there is life in such a place."
Some people lament the magic and greatness of life.
It stands to reason that in an environment like Mars, it is impossible for anything to exist. However, Mars not only has life, but it also seems to be thriving. The population and quantity of these microorganisms are quite good.
"Where did the life on Mars come from? And how did it multiply?"
Zheng Yuan looked at the microorganisms he saw in the microscope. Just by looking at their appearance, he knew that these microorganisms were not the simplest single-celled organisms, but life that had evolved and developed to a certain extent.
Such life should appear on a planet like the Earth, not on a planet like Mars, but now it has appeared on Mars, and it seems that they are thriving well.
This forces people to think carefully, where did this Martian life come from?
How did it continue and multiply in such a harsh environment as Mars?
"Continue to study and analyze these microorganisms and do a good job in protection."
Zheng Yuan thought hard and couldn't find the result, so he gave the order after thinking about it.
"Yes~"
Many scientists and researchers quickly replied in unison, and each of them continued to be busy.
"Amino acids have been found in the remains of Martian lakes, and there are dozens of species."
Research continued, and soon, new major discoveries were made. A large number of amino acids were discovered in what were suspected to be the remains of ancient lakes on Mars.
If there are amino acids, just say that there used to be a lot of life in this lake. Only life can produce amino acids, and nature cannot produce amino acids.
"Amino acids found in lake ruins?"
When Zheng Yuan heard this, he immediately became energetic.
Now not only have Martian life been discovered under the ice at the North and South Poles, but a large number of traces of life have also been found in the remains of lakes. What does this mean?
This shows that life existed widely on Mars a long time ago.
"Amino acids are also found in river remains."
Soon, as expected, a large amount of amino acids were also found in the river ruins, which is enough to prove that there once was a large amount of life on Mars.
At the same time, it can also be explained that there used to be a large amount of liquid water on Mars. It was the existence of this liquid water that allowed a period of prosperous life on Mars. Maybe a long time ago, Mars was still the same as the earth.
It is hard to say that a planet with prosperous life could even evolve advanced species.
This may have happened a long time ago, so long ago that it could be measured in hundreds of millions of years, hundreds of millions of years ago, billions of years ago, or even billions of years ago.
Humanity still knows too little about the history of the solar system.
It can even be said that we know very little about the history of the earth. Very little. We can only study the previous history of the earth through some ancient fossils.
Of course, not to mention the history of the earth and the solar system, even the history of human beings has not been thoroughly studied. Based on genetics and analysis of ancient human skeletons obtained from all over the world, it can be concluded that human beings originated in Africa?
Is this scientific?
Judging from the current science, it must belong to scientists, because genes cannot lie.
But is it the truth?
This is not necessarily the case. There are too many things buried in the long river of history. It is difficult for future generations to know everything that happened in history, not to mention the origin of human beings.
There is no age in the text, so you know it must be like this?
Some people may ask, is history that important?
Do you have to figure this out?
The answer is yes, history is of course important, and the origin and development of human beings are also very important. Once you understand all this, you can naturally know the origin and origin of human beings.
What scientists study is not only the origin of human beings, but also the origin of species on earth and the origin of life on earth.
Why is the earth alone alive?
Are there no other planets?
Why haven't we discovered extraterrestrial civilizations until now?
Is it because of the barrier of the vast starry sky that we are far apart from each other, so we are unable to know each other's existence?
Or is it because our earth's technology is too low-level that we simply cannot discover technologically advanced alien civilizations?
Or is it, as everyone has always believed, that the earth is the only living planet in the universe?
There are too many, too many mysteries waiting for us to unravel and discover.
What humans currently know is still too little, too little.
"Mr. Zheng, this is a map of ancient Mars that I constructed based on simulations of the rivers, lakes, and ocean ruins currently discovered on Mars."
A scientist sent a message to Zheng Yuan.
Zheng Yuan opened it as soon as his mind moved, and a large amount of information immediately poured into his mind.
This is a computer-generated image. According to this image, it can be clearly seen that a long time ago, Mars was a blue planet similar to the Earth. The northern hemisphere of Mars was covered by oceans.
The Southern Hemisphere also has rivers and many lakes, making it a planet full of life.
"According to our analysis, the water on Mars has been lost mainly due to two reasons. The first reason is Mars itself, because the diameter of Mars is less than 7,000 kilometers, the volume is only 15% of the Earth, and the mass is only
About 10% of the dead Earth.”
"So the cooling time of Mars' own core is much faster than that of the Earth. The core does not receive enough pressure and gradually cools down after a period of time."
"The cooling of the core caused a large amount of water on the original surface to penetrate into the entire planet. This should be the main reason for the disappearance of water on Mars."
"This is also the reason why Mars has no plate movement and there is a huge 20,000-meter-high Olympus Mons on Mars, which also causes Mars to lose its own magnetic field."
"Of course, the cooling of Mars' core is most likely due to the impact of a huge asteroid. The huge impact released the energy of the core prematurely, causing it to cool down prematurely."
"The second reason is that because the core of Mars has cooled and lost its magnetic field, Mars has no protection from the magnetic field. The erosion of Mars by the solar wind has become extremely severe, taking away a large amount of atmosphere and water, making the atmosphere on Mars become thinner and less water.
disappear slowly."
"After we collected and analyzed data from all aspects, we believe that many billions of years ago, when the core of Mars had not yet cooled down."
"Not only is there a large amount of liquid water on Mars, but the density and thickness of the atmosphere on Mars are much higher than now. The temperature on the surface of Mars should also be dozens of degrees higher than now. In such an environment, Mars is very likely to
It is a living planet like the earth."
There are not only simulation diagrams, but also detailed analysis reports.
This is not a random guess, but an inference based on the scientific research results on Mars.
There are remnants of rivers, lakes, and oceans on Mars, which shows that there was once a large amount of liquid water on Mars, and signs of water erosion can be found on the surface of Mars.
At the same time, the existence of life has been found at the North and South Pole of Mars, and a large amount of amino acids have been found in various places on Mars. These all indicate that Mars once had a large amount of life and was a living planet.
It’s just that no fossils of ancient life have been found on Mars yet. Of course, this may be because it is too long ago. In addition, Mars has no plate movement or earthquakes due to the cooling of its core. Ancient fossils are difficult to form and
Save it.
"Mars is just the planet closest to the earth in the solar system. Life was actually discovered on this planet. It was still a living planet in ancient times."
"This is enough to show that life should be widely present in the interstellar universe, the earth should definitely not be the only life in the universe, and human civilization is definitely not the only intelligent life and civilization in the universe."
Zheng Yuan read it carefully and started thinking.
Judging from current signs, life should be widespread in the universe. In this case, the existence of aliens and extraterrestrial civilizations must be an inevitable result.
"Why haven't we encountered any alien civilization until now?"
"Could it be said that all civilizations are similar to our earth civilization, with limited technological level and unable to cross the starry sky and the universe? Therefore, even if there are a large number of civilizations in the universe, they are unable to communicate with each other and cannot be known."
Zheng Yuan thought about it, and soon thought of a possibility, that is, the interstellar universe is too vast and boundless, and technology has not developed to a certain level, and interstellar routes are simply impossible.
"But if life exists widely in the interstellar universe, then where does life come from?"
PS: Do you think there are alien civilizations in the universe?
