America, California Institute of Technology, School of Astronomy:
Several dozen astronomers and researchers sat in the hall and quietly watched Chen Yu's livestream.
Beside them, an Asian man was also performing a professional simultaneous translation.
Meanwhile, as Chen Yu continued his narration, everyone shuddered and broke out in a cold sweat.
They were professional astronomical researchers, so they had a much deeper understanding of what Chen Yu said than ordinary people.
Even before gravitational waves appeared, Einstein had concluded that such things existed.
Before humans had left Earth, the ancient Greek mathematician Pythagoras had deduced that the Earth was round.
In the scientific community, there were some things that didn't need to be witnessed.
Facts could be speculated.
For example, the "ninth planet" Chen Yu spoke of. Since last year, the astronomical community had discovered an anomaly on the planet. Moreover, as more research went on, this anomaly became increasingly terrifying.
Until today, when Chen Yu's livestream made all the researchers who had studied the ninth planet instantly realize the truth...
The so-called ninth planet's true face...
...
Deep in the ocean, inside the island-building ship's study, Chen Yu's narration continued.
"When observing Uranus in the past, astronomers speculated the existence of Neptune based on Uranus's orbital anomalies.
Then, Neptune was discovered. "
"In the solar system, most planets are discovered in this way.
Through gravitational pull, they can sense each other's existence.
"Hence, in 2016, everyone believed that the ninth planet would be discovered soon. However, in the following period, no matter what methods the astronomical community used, they couldn't directly discover the existence of this mysterious planet.
"It was as if this celestial body didn't exist.
"Until 2019, when more and more astronomers noticed that something was amiss."
After saying so, Chen Yu flipped through a dozen pages of the journal and showed a set of data to the camera.
"This is the information observed on this celestial body in 2019.
According to one set of data, this celestial body takes 30,000 years to complete a revolution around Earth.
According to the second set of data, this celestial body is not born in the solar system.
"Because the Kuiper Belt is a remnant left after the solar system's formation, it is almost impossible for such a large planet to form.
Hence, this celestial body is an outsider, and its existence is also a fact.
There is no doubt about it.
"Here comes the problem..."
Straightening his mask, Chen Yu spoke in a deep voice.
"A celestial body that exists in theory, a celestial body heavier than ten Earths, and a celestial body that affects the orbits of countless asteroids around it, why can't we discover it?
Why can't we see it?
Why can't I touch it?
It can only be detected by gravity but not by light? "
"In October 2019, physicists Jacob Schultz of Durham University and James Enwin of the University of Illinois proposed a bold idea..."
After saying so, Chen Yu flipped to the journal's 13th page and showed a black-and-white photo of two researchers. "It's these two."
"Their conjecture is that this celestial body cannot be observed because it is not a planet at all …"
"It's a black hole."
Bang!
Closing the journal, Chen Yu took a deep breath and faced the camera, saying, "Unfortunately, their guesses are correct."
"It is a black hole."
As soon as he said that, the livestream exploded!
[Nani?!]
[Stop fooling around, big brother …]
[You're f * cking telling me that there's a black hole in the solar system?]
'My worldview …'
[Impossible!]
[Impossible!]
[Title clickbait complete.]
[Mr. Lu once said, 'After eliminating all the impossible facts, the remaining facts, no matter how unbelievable, are the truth.']
[Did Mr. Lu really say that?]
[I think Alexander the Great said that.]
[It was obviously Taishang Laotzu.]
[Bullshit!
Pan Jinlian said it!]
[Dammit!
Are you not afraid at all?
A black hole!
Hey, that's a black hole!!]
[A white hole. A white tomorrow awaits us …]
[I'm going back to the countryside to take refuge.]
After a brief burst of bullet comments, the livestream fell silent.
Chen Yu also fell silent as he waited for his seven million viewers to digest this bad news.
A minute later, Chen Yu flipped to the middle of the journal and continued, "According to the latest research report from 2033, this is a primordial black hole. Its true mass is 125 times that of Earth and the size of a football.
"Based on speculation, this black hole has existed in the solar system for at least a billion years.
"Hearing this, some of you might breathe a sigh of relief and think that a black hole that has been safe for more than a billion years can't possibly cause us any harm.
However, on the contrary, after more than a billion years of revolution, this black hole is getting closer and closer to the solar system's interior.
"In this 2019 research report, it has been speculated that 100,000 years ago, this celestial body still took 40,000 years to orbit the sun.
Now, there were only thirty thousand years left.
At that time, people still couldn't understand this strange orbital change.
"However, if it's a black hole, everything can be explained."
Stretching out three fingers, Chen Yu said, "300,000 years. In just 300,000 years, this black hole will appear in front of us.
"This is indeed a long time. Most people in front of the screen won't care, but you've overlooked one thing.
There are many celestial bodies in the solar system... "
Amidst the bullet comments, Chen Yu flipped to the second half of the journal and sped up his speech.
"According to speculation, 12,000 years later, the black hole will collide with an asteroid named 2018 VG14.
The collision of VG14's asteroids will cause a shockwave that will sweep through the entire solar system.
"6,400 years later, under the gravitational pull of the black hole, Sedna's orbit will continue to shift, resulting in a series of complex chain reactions.
At that time, the angle of Earth's orbit will definitely be affected, resulting in an orbital deviation.
"700 years later, the black hole will be closest to the sun during this revolution, only 320 astronomical units away from the sun.
"Twenty-five years later, an asteroid named 2034 VG14 will pass by the black hole.
"VG22's planet, Gisella, will pass by the black hole. According to computer analysis, this planet will be torn apart by the huge gravitational force and fly into the inner solar system at an angle of 78 degrees. It may collide with the sun and cause devastating consequences …"
"Three and a half months later..."
Pausing, Chen Yu looked at the camera and enunciated clearly, "The black hole will be 315 astronomical units away from Jupiter in 30,000 years. The chain reaction will cause the orbits of many near-Earth asteroids to change.
One of these asteroids, an Almo-type asteroid named Bell, will directly collide with Earth.
"In other words, we don't need 300,000 years, 10,000 years, 6,400 years, or 25 years."
Standing up, Chen Yu shrugged and said, "We only need three and a half months to feel the real threat this black hole poses to us.
"This is also the moment of life and death I mentioned.
"Humans only have three and a half months to deal with this asteroid.
Then, within 25 years, we'll deal with the asteroid Gisella. "
"Otherwise, even if human civilization doesn't become history, it will still suffer unbearable damage."
Stepping out of the study, Chen Yu followed the camera into the island-building ship's hall. He then arrived before the protective suit's maintenance cabin and opened the hatch.
"Now, I'll take everyone to see that black hole with their own eyes and confirm its existence 20 years in advance..."
