Chapter 166: The Special Features of Earth

After saying this, he wrote the two characters [Atmosphere] on the whiteboard on the table.

He held it up, facing the camera, "As you can all see, the fifth point is the atmosphere."

"As everyone knows, the universe is everywhere emitting radiation that is harmful to the human body."

"And our [Atmosphere] is just right, ensuring that [useful] radiation enters the Earth. Everything else is shielded."

"What does that concept mean?"

"It's like high-intensity ultraviolet rays, as well as extremely strong [Gamma Rays], which are rays that life does not need to exist; therefore, our atmosphere significantly weakens ultraviolet rays, as well as all gamma rays and the like; even if it doesn't shield all radiation, our Earth's [Ozone Layer] also significantly weakens it and shields the [Threshold] that could potentially cause harm to the human body."

"In the end, the radiation that is useful to us humans remains; unnecessary radiation is entirely reduced and shielded."

"This is one of the miraculous parts!"

Regarding this, some viewers nodded silently.

They briefly explained it in the live stream for those who didn't know, and all the viewers suddenly realized.

"So, you mean our atmosphere and ozone layer achieved 'just right'?"

"Yes, they both reached 'just right', which is why there were dinosaurs, and why we exist."

"Damn, this feels so amazing, it's more like it was designed."

"Yeah, anyway, I can only say that ignorance is bliss; not understanding anything is the happiest state!"

"..."

While the viewers were discussing, Jiang Zhe's explanation continued.

"And what we need is only [Light]."

"Saying [Light] is still a bit too general; what we need is [Visible Light]!"

"And this [Visible Light] is still 'just right' enough to shine on the surface, allowing us to bathe in the light and feel the warmth."

As he finished speaking, he quickly doodled on the whiteboard, turning it black.

Then he wrote four rows of words. They were: [Electromagnetic Waves], [Infrared], [Ultraviolet], [Gamma Rays].

Finally, he replaced the space between Infrared and Ultraviolet with scratches from a seven-colored marker.

He held it up to the camera again.

"As you can all see again, this is the analysis of past scientists."

"This is the [Radiation] emitted into the Earth from the universe."

"Electromagnetic waves and most infrared, ultraviolet, and gamma rays are in the black area."

"And the [Colored Line] between infrared and ultraviolet is the [Light] that we can see with our naked eyes."

"It just so happens that this narrow gap of [Visible Light] is useful to us, while the rest of the areas I blackened are harmful to the human body."

"It just so happens that our Earth's atmosphere can provide exactly this function."

Speaking of this, Jiang Zhe's mouth curled slightly, and he asked rhetorically: "Isn't it very special?"

Once these words were spoken, all the experts and viewers nodded like chicks pecking at rice.

The experts had long experienced this miracle, but many viewers were receiving this knowledge for the first time, and they felt it was extremely amazing!

"Wow, if it were off by even a little bit, or if it were any further away, we wouldn't be able to live on the surface!"

"Yeah, as a college student studying biology and geography, it really feels amazing to encounter this for the first time."

"Why is that? So much evidence indicates that our Earth seems very special!"

"Look at you, getting impatient again. He hasn't finished yet; the special parts haven't even arrived."

"Then I'll stop talking and keep watching."

"..."

Gradually, no matter who they were, everyone was listening silently.

Although this content wasn't explosive, it made people feel the wonders of the Earth.

Jiang Zhe's voice soon came from the live stream.

"For everyone, perhaps many planets have atmospheres, but their atmospheres are incredibly murky, so murky that even sunlight cannot shine through."

"Only the atmosphere on Earth is [Transparent]; only on Earth can these sunlight rays shine through."

"At the same time, what you also need to understand is: oxygen, nitrogen, and carbon dioxide."

"The reason other planets' atmospheres are murky is that the proportions of those gases are severely imbalanced, which leads to a murky atmosphere, and thus no life appears."

"But the composition ratio of our Earth's atmosphere: nitrogen, oxygen, and carbon dioxide are in just the right proportions, which allowed us to appear; if it were even slightly imbalanced, the atmosphere would quickly become murky, and before long, humanity would completely perish from the Earth!"

"Next, the planet also needs to have land and oceans."

"Purely oceans cannot support the birth of complex life; only a piece of stable land can evolve higher-level organisms. Taking humans as an example, even if our ancestors many years ago might have been fish, they eventually developed onto land to become primates, and then humans."

The viewers were not unfamiliar with this knowledge.

Summed up in one sentence: it just needs to be [Just Right].

If it is [Not Just Right], then everything would drift away with the wind and vanish into the torrent of time.

"Next, that planet's crust must also be relatively thin; if the crust is not thin, there would be no tectonic movement."

"Without tectonic movement, there would be no chemical reactions, and without chemical reactions, there would be no various chain reactions."

"Like single-celled, multi-celled, or even organisms and higher-level organisms, they are all obtained through massive chemical chain reactions."

"Some are part of the matter brought by asteroid impacts, some are brought by the movement of tectonic plates, and so on."

Speaking of this, Jiang Zhe raised his hand toward the moon outside the window, "Everyone can tell by looking at the moon; the moon has maintained its appearance for millions of years; the only things that change are the various craters."

"The moon's thickness is only about 6 kilometers. I don't mean the moon is only 6 kilometers thick, but that its lunar crust is relatively thick and hard; beneath those 6 kilometers is a thick layer of titanium alloy."

"Resulting in all meteorites, regardless of size, only being able to hit it 6 kilometers deep!"

"Previously, in my spare time, in a popular science program from another province, an unprofessional host seeking traffic said—"

"The United States NASA probe detected [Longitudinal Waves] on it, which means the inside of the moon is hollow, and there is water sloshing around."

"He also said that the [Titanium Alloy Layer] is the outer shell of a spaceship."

"When I saw this at the time, I just grinned."

After saying this, Jiang Zhe still couldn't help but laugh. Back then, that host from another province said the moon was monitoring Earth, always keeping one side facing Earth, and once Earth had any unusual movement, the moon would fire."

To this day, Jiang Zhe still couldn't escape the wild imagination of that host from another province.

Perhaps the first half was fine, as ordinary people cannot detect evidence; but the second half was just wild imagination.

Once these words were spoken, the viewers were stunned, and then many people blushed.

"Ah? Isn't the moon monitoring the Earth?"

"No, it definitely isn't; I can find that report on the NASA official website. The inside of the moon is not sloshing around; saying there is water is fine, but how could it be sloshing..."

"Damn, I get it now. Jiang Zhe, you are a rumor crusher; any perfectly good science fiction can be debunked by you; you really live up to your program's name, [Debunking]!"

"Ahem, I will no longer question the host's professionalism; because... he is just too damn professional!"

"Listening to a professional talk about professional things is truly a wonderful thing!"

"..."

Jiang Zhe didn't know that his popular science lessons caused some children to suffer.

In Su City, many parents at home immediately picked up their belts and gave their children a beating.

"Snap!" sound.

The father scolded angrily: "Who told you the moon is monitoring the Earth? You don't study properly, and you just watch those unprofessional science shows."

The mother followed up with a lash: "You brat, I told you to read more books, but you insisted on going to the countryside to learn how to raise pigs with your grandma; look at you now; you've made a fool of yourself; you even dared to say in a school speech that the moon is monitoring the Earth; if Teacher Jiang hadn't clarified it today, I would have almost believed your nonsense!"

As a result...

The child said with a crying face: "Mom and Dad, I was wrong; I didn't say it; it was my teacher who said it; he said it because he watched another host's science show!"

"Pah! And he's a teacher?"

"Not professional at all, teaching children nonsense; I forbid you from attending your teacher's astronomy class anymore; from now on, you will watch Teacher Jiang's TV program."

Under the tyranny of his parents, the twelve-year-old child could only nod repeatedly, "I promise, I won't miss a single one of Teacher Jiang's science lessons from now on."

Situations like this happened in a small number of families.

Parents do not want their children to go astray, so they dragged their children to watch it forcibly; if they watched even a little less, they would have to accept a 'mixed doubles' beating.
