Chapter 162: The Earth Special Hypothesis

"Based on the comparison between ancient oxygen levels and current oxygen levels, it is indeed as Jiang Zhe said."

"If humans really existed on Mars, based on scientific evidence, those Martians would be at least 2.5 meters tall on average."

"Yes, to us modern Earthlings, they would simply be giants!"

"But that's all in the past. Let's see what he says about Venus; I personally believe that it's actually possible that intelligent humans appeared on Venus, and the humans there would have an average height of around 1.9 meters, calculated based on the difference in Gravity."

"Venus? That's probably unlikely. Current evidence indicates that it's almost impossible for humans to have existed on Venus, but Venus many years ago was indeed similar to Earth's environment; there might have been some small fish or shrimp-like creatures."

"..."

Inside the lecture hall, the experts' opinions quickly diverged due to Jiang Zhe's explanation.

However, most experts still believed that intelligent civilization had never existed on Venus.

At this moment, on the big screen.

Jiang Zhe continued to explain:

"Regarding the [Venus] that everyone is concerned about..."

"Referring to Earth, from the first life to modern humans, it took a total of 3.8 billion years."

"Venus is 5.925 billion years old. A simple calculation: subtract 3.8 billion years, and you are left with about 2.125 billion years."

"These 2.125 billion years mean that Venus was constantly in a habitable zone and was a habitable planet, without so many extreme climates and natural disasters."

Facing the camera, he suddenly grinned, "Yes, I'm sorry to disappoint everyone. There is data indicating that oceans existed on Venus in its early stages, but the later Venus really didn't have the chance or the time to evolve complex life."

"If it evolved cyanobacteria or small fish and shrimp, that might be possible. Even if they existed, those fossils would most likely be underground on the surface of Venus."

"If they were on the surface of Venus, the former Russia, which has studied Venus the most, would definitely have discovered fossils of small life forms there; but in reality? No, they haven't discovered anything at all~"

"Therefore, Venus is not as magical as everyone imagines. It really has never hosted intelligent civilization or humans."

"By the way, regarding planets in the entire universe, I can guarantee—there are indeed numerous planets that harbor life like small fish and shrimp; but as for the appearance of humans, that remains to be discussed."

As soon as these words were spoken, the previously confident experts and audience members looked disappointed once again.

They realized that Jiang Zhe was a myth-buster and a fantasy-killer.

Every time they excitedly and enthusiastically proposed a point of view, Jiang Zhe would always refute their opinions from a novel perspective.

At this point, many audience members were going crazy, especially those astronomy graduate students who had previously been popularizing science for the audience. They were incredibly embarrassed, having confidently declared: [Venus has life], only to be slapped in the face by Jiang Zhe the very next moment, it stung!!

"Who? Who was that fake biology or astronomy graduate student who said Venus had humans? Come out here!"

"Exactly, exactly! Did you buy your graduate degree?"

"This... don't blame me. My professor said the same thing; Venus had many, many years of development time; intelligent human life must have evolved there during that process."

"Yeah, and Jiang Zhe said that it took over 3 billion years for the first life on Earth to develop into modern intelligent humans. Venus really did have an environment similar to Earth's a long time ago!"

"To the person above: similar is similar, but Venus's total lifespan is 5.9 billion years, and Earth's is 4.9 billion years. There is a 1-billion-year difference. How can you guarantee that Venus gave birth to its first life around 1 billion years after its formation? The time from the first life to the appearance of intelligent civilization and humans is 3.8 billion years; 3.8 + 1 = 4.8 billion years. Even if there were humans, that would be 1.1 billion years ago... Wait, does it seem actually possible?"

"Yeah, as long as Venus maintained an environment similar to Earth's early environment in its early stages, it is indeed possible."

"To the person above, let me tell you with the latest research data: 3.9 billion years ago, Neptune's orbit shifted outward, disrupting the Gravity of asteroids in the Kuiper Belt. Countless water ice and rocks flew toward Venus, Earth, and Mars. After being impacted, Venus no longer rotated from west to east like other planets, but instead rotated in reverse at an extremely slow speed—thus, a spectacle appeared among the planets of the Solar System: the sun on Venus rises in the west and sets in the east. It takes about 243 Earth days to rotate once, and about 224.7 Earth days to revolve once. In other words, Venus almost doesn't rotate."

"So, those who claim to be graduate students, please relearn the basics of astronomy; Jiang Zhe is right, it takes a minimum of 3.8 billion years to evolve humans; Venus's total lifespan is 5.9 billion years, minus 3.9 = 2 billion years. Even if Venus was in an oceanic period from the first day it formed, it was only 2 billion years until Venus lost everything. 2 billion years is not enough to give birth to humans; therefore, Venus could indeed have had small fish and shrimp in its early stages because there was a large area of ocean, until 3.9 billion years ago, when they completely disappeared. Venus is also Earth's older brother who died prematurely!"

As soon as this bullet comment appeared, the arguments in the live stream room quickly diminished.

Upon careful thought, it was indeed so. Jiang Zhe had never deceived anyone, and he always started from factual evidence.

...

Inside the leadership conference room.

After listening to this part of the explanation, Old Zhao showed a look of regret on his face.

"What a pity. Venus was an ocean many billions of years ago. If it had been given the right amount of time, it would surely have evolved intelligent humans, right?"

Broadcasting Minister Old Wang nodded in agreement: "Definitely! Given the right amount of time, it would certainly have appeared!"

Unexpectedly, Xiao Shiyi directly refuted them: "I told you two to read more, read more, but you insisted on drinking and having fun."

"What's wrong?" x2

The two looked at Xiao Shiyi with wronged expressions.

Xiao Shiyi looked at Wang Lin and found that Wang Lin was watching the live stream, so he explained it himself: "Humans would not have appeared; because early Venus was in the habitable zone, it was because when the Solar System was just born, Venus was indeed located within the habitable zone, as the sun's brightness was relatively low at that time, and Venus's environment was suitable for life to exist."

"However, as time passed, the sun's brightness gradually increased, which caused the temperature on Venus's surface to rise sharply, making it no longer habitable. It can also be said that the habitable zone within the Solar System gradually moved further and further away, eventually forming today's high-temperature and high-pressure environment."

"Similarly, Earth will not remain habitable in the next 1 billion years. By then, our Earth will follow the same path as Venus."

"Of course, that is assuming our human civilization can last for 1 billion years, but when you think about it, it's unlikely to last that long."

Wang Lin quickly chimed in: "Xiao Shiyi is right; according to the solar sunlight density map, after Earth is no longer habitable, Mars, which is located behind Earth, will then become the habitable zone. Mars's core is dead now; if Mars becomes habitable in 1 billion years... through various chances and coincidences, it is highly possible that Mars will be resurrected. It might be future humans who go to resurrect Mars and transform it into a habitable planet."

Following the explanations from the two young big shots on the scene, all the experts then awkwardly smiled.

"I didn't expect it to be like that!"

"So whether it's habitable or not depends on the increase in solar heat!"

"When that time comes, once the sun's lifespan completely ends, the Solar System will be gone, and even the habitable zone will be gone."

"..."

While they were discussing, on the big screen, Jiang Zhe spoke up.

"Perhaps some audience members have already realized—"

"The habitable zone of the Solar System is constantly changing; Earth will become uninhabitable in 1 billion years, and the habitable zone will then become Mars."

"That's why scientists list Mars as a habitable planet, of course, 1 billion years from now."

"Alright, through the Ordinary Earth Theory, we conclude—the development from the birth of life on Earth to modern humans is a very ordinary process."

"If life and humans appeared simply based on the habitable zone, then Venus indeed had a human civilization, but unfortunately; another factor for the emergence of life in the habitable zone is looking at how long the planet's lifespan is. If its lifespan is long enough and the habitable period is long enough, indeed, on some day after a comet impacts the planet and brings in some foreign matter, and then under physical and chemical reactions; life will indeed appear. Life will pass through a safe cycle to form complex organisms, eventually leading to primates, and then to humans."

"It can be said that the appearance of life like humans is very difficult; but looking at the entire universe, it is very ordinary!"

At this point in the explanation, Jiang Zhe took a deep breath, "Alright, since I've finished explaining the Ordinary Earth Theory, proving that the conditions for the emergence of life are not too complex; let's now switch to the next hypothesis: 'The Rare Earth Hypothesis'"
