Sitting on the sofa, Chen Yike held onto her phone. When she saw Chen Yu's figure appear on the screen, her eyes immediately glowed.
"It's finally livestreaming!"
Standing up abruptly, Little Peach started recording the livestream. Afterward, she carefully placed her phone on the coffee table, picked up a screaming chicken, and tiptoed toward Chen Yu's room.
"Big Sis, what are you doing?" Chen Erke, who was playing with her phone on the sofa, asked in confusion.
"Shh!"
Making a shushing gesture, Chen Yike walked through the living room and up to Chen Yu's room. She then carefully listened to the movements inside.
"Big Sis, what are you doing?"
"I'm revealing a big secret!"
"Secret?" Chen Erke was surprised.
"Shh.
Don't speak. Stand behind me obediently. "
"Oh!"
"Huh?" Chen Yike suddenly became a little dazed. "Don't you find this scene somewhat familiar?"
"Familiar in what way?"
"It feels like I'm watching some evil author rewrite the previous plot..."
"Nope."
"It must be my imagination..." Chen Yike mumbled. After sticking her ear to the door for a while and discovering no sound, she picked up the screaming chicken with a mischievous smile and prepared to make a noise.
If Chen Yu were inside, she was certain that he would get a fright.
If there was no reaction from such a sudden attack, it was enough to prove that there was no one inside!
"Second Eldest, cover your ears. Don't be afraid," Chen Yike whispered.
"Is it a prank?" Licking her lips, Chen Erke excitedly covered her ears.
“3。”
“2。”
“1！”
"Oh!!!"
The screaming chicken instantly made a noise!
However, in the next moment, the door was pulled open without any warning!
"You …" Before Chen Yike could react, a stick fell from the sky and hit her head with a "dong" sound.
Thud.
Seeing Chen Yike fall to the ground, Little Peach eagerly picked up the Amnesia Bat and smashed it into Chen Erke's head.
Thud!
Thud!
Erke also softly fell to the ground and fainted.
She still had her hands covering her ears...
Bending down, Little Peach picked up the screaming chicken on the ground and admired Chen Yu. "When the 'chicken' is in trouble, you can take the initiative to attack!
Are you talking about this' chicken '?
So, Mr. Chen already predicted this. Amazing. "
"W-Who are you?!
What are you doing?! "
Hearing the commotion, Mother Chen walked out of the master bedroom. When she saw Little Peach and her two daughters lying on the floor, she was immediately shocked.
Swoosh!
In the next moment, Little Peach appeared beside Mother Chen as if she had teleported. She then knocked Mother Chen to the ground and shouted, "Take the initiative to attack!"
Then, she knocked both Chen Sanke and the Husky down with her hands on her hips.
"My, Little Peach's, stability is the true stability …"
…
At the same time,
Floating Castle, Headmaster's Tower study.
In a solemn tone, Chen Yu explained everything about Tabby's Star to the audience.
"As we all know, if a star has a planet revolving around it, then when the planet 'blocks' the star, it will cause the star's luminosity to decrease.
This phenomenon was called the transit of the sun.
Modern astronomers use the transit method to obtain information such as whether or not there are planets in other star systems, how many planets there are, and the mass of the planets. "
"But under normal circumstances, this luminosity decrease is only about 1%, or even less."
"And strange times, kic.
The luminosity of 8462852, or Tabby's Star, had decreased by up to 22%!
This is completely beyond common sense.
In humanity's current star system model, it is impossible for such a drastic luminosity decrease to occur on its own.
"Hence, after 2011, the astronomical community has come up with some authoritative hypotheses for this phenomenon."
Flipping to the seventh page, Chen Yu showed the text in the journal to the camera. "First, the cloud hypothesis.
After ruling out equipment or data problems, the Monthly Notices of the Royal Astronomical Society believes that Tabby's Star's luminosity decrease may be due to the gravitational influence of the surrounding star, causing a large number of comets in Tabby's Star's Oort cloud to fall toward the star.
"The evidence supporting this hypothesis is that there is indeed a red dwarf 885 astronomical units away from Tabby's Star. The red dwarf is also very close to Tabby's Star and has the ability to affect the comets in Tabby's Star's Oort cloud.
"However, in 2016, two Chinese astronomical institutions ruled out this hypothesis after conducting calculations.
This is because after Tabby's Star's comet cloud is disturbed by gravity, it orbits the star in an elliptical orbit.
The comet cloud does not have enough mass to cause a 22% luminosity decrease. "
Pausing slightly, Chen Yu gave his audience a ten-second buffer. He then flipped to the eighth page and continued, "Second, the planetary collision hypothesis.
Several planets orbiting Tabby's Star collide, producing warm dust that blocks the star's light.
However, the collision between planets will emit intense infrared light!
Meanwhile, through high-resolution spectrometers and the Nordic Optical Telescope in East Spain, the astronomical community has analyzed the spectral energy distribution for several years. However, they have not observed any excessive infrared energy.
"The planetary collision hypothesis is self-defeating.
"Aside from these two, there are many other explanations that are less likely.
For example, instrument data errors, volatile BE stars, cosmic dust, companion stars, protoplanetary disks, and so on.
"For every hypothesis, there is plenty of evidence to prove them wrong."
Putting down the journal, Chen Yu looked at the camera and said in an even deeper tone, "Only a seemingly absurd but impeccable hypothesis can explain the decline in Tabby's Star's brightness.
Since 2015, more and more astronomers have been inclined to this view.
It's not because they have found evidence, but because all other hypotheses have been declared wrong.
"As Sherlock Holmes said, once you rule out the impossible, the remaining hypothesis, no matter how unbelievable it is, is still the truth.
"This hypothesis is the civilization's creation hypothesis!"
[Crap!]
[Stop messing around...]
[Why does this feel like a joke?]
[There are many people in the industry who truly believe this. I am one of them.
You guys might not understand, but the various countries' governments and astronomical communities are paying a lot of attention to this star!]
[I still don't understand.
Does it mean aliens?
Can it come over?!]
[It can't be a Dyson sphere, right?
This thing is actually quite retarded...]
[More than 1,400 light-years is already very close.]
[It's scary to think about it.]
[Eliminate human tyranny!
The world belongs to Tabby's Star!]
After waiting for the bullet comments to subside slightly, Chen Yu picked up Civilization's Shining Moment again and flipped to the tenth page. Pointing at the photo of a white man, he said, "Many astronomers agree with the civilization's creation hypothesis. However, this person is the first to publish a related professional paper.
He is Jasht, an astronomer at Pennsylvania State University. He is still active even now.
In that paper, it is clearly hypothesized that the luminosity change of Tabby's Star is most likely caused by a giant structure built by an alien civilization.
For example...
"A Dyson sphere."
Closing the journal, Chen Yu stood up and spread his arms. "Jasht, you should be watching my livestream right now. Congratulations to you and Pennsylvania State University.
Half of your reasoning is correct. "
"The non-periodic brightness change of Tabby's Star is indeed caused by a giant structure created by some intelligent life.
"Next, I will throw out a series of indisputable evidence, including several new discoveries made in 2019, to prove your point.
"Meanwhile, the reason why I say half of your reasoning is correct..."
Walking away from the camera, Chen Yu picked up the delivery box containing the 22nd century astronomical telescope and said, "It is because this giant structure isn't the so-called Dyson sphere.
"Instead...
