Bai Yang immediately informed his father of this important discovery.

The old man was there, he waved his hand and said, what kind of important discovery is this? What a big deal, the paintings on the wall are gone, it means the putty has been shoveled away, something will definitely happen in the future and all the putty in your room will be shoveled away.

Refresh, do you believe it?

If you don’t believe me, I’ll leave the words here and wait. You can come back and read them later if this happens.

Dad acted like a prophet.

Bai Yang scratched his head. After discovering that the image on the wall disappeared, he imagined tens of thousands of words of the plot of a science fiction blockbuster. What about parallel universes, multiple histories, world line jumps, plot twists and turns, touching, and Taro Gambrenta is about to be possessed.

, preparing to cross the world to save Makise Kurisu and Dudulu, but his father revealed the secret.

Bai Yang cast his gaze at Uncle Wang beside the coffee table.

Lao Wang didn't even raise his head and was not interested in what Bai Yang said. He just signed his name on the article written by Xiao Zhu.

Bai Yang had no choice but to turn his head and look back.

Forsythia leaned against the door of the room, spread her hands and shrugged.

Zhao Bowen is in a meeting.

Not at the provincial and municipal committees, but at the Purple Mountain Observatory.

He was having a normal meeting today to report on the current work progress of the headquarters. Unexpectedly, he suddenly received news from Zitai. He quietly turned on his mobile phone and saw that he had made a major discovery. So Lao Zhao half-said and wrote the manuscript

He threw it away, pushed the table, dragged the chair, and ran away, leaving all the leaders stunned.

The leader quietly asked his secretary if there was a fire at home.

"Can it be clearer?" Zhao Bowen frowned. There was a photo on the PPT, and a stack of photos was spread out on the table in front of him.

"Uh...Teacher Zhao, you also study physics, and you know..."

"I just want to know, can it be clearer?" Zhao Bowen interrupted.

The background of the photo is black. There are a few sparse white dots on the black background, like chalk dust scattered on a blackboard, and a dark red arrow pointing to a dim dot in the center of the photo.

The label at the bottom is SgrA.

Zhao Bowen, a pure layman in astronomy, also knows that SgrA is the Sagittarius A star. The sesame-mung bean-sized spot in the photo is actually a super-giant black hole with a mass of four million times the sun. Sitting in the conference room, you can't tell it at all.

, Zhao Bowen's head couldn't imagine how big it was with four million times the mass of the sun, but fortunately the director explained that it was a black hole, not a star, so even though its mass was as large as four million times the sun

, but its diameter is actually only 40 million kilometers.

The photo in Zhao Bowen's hand is an enlarged version of SgrA, with lower definition and black and white color. The dim white dot on the PPT is enlarged hundreds of times and it is the photo in Zhao Bowen's hand. The clarity is even better than black sesame paste.

It's blurry, but you can still roughly see that the structure is a fuzzy, hazy ring without any details.

Old Zhao inexplicably remembered the big eye he saw that night, which had a similar pupil. This association made Zhao Bowen shudder. Isn't the characteristic that even light cannot escape from a black hole similar to that eye? Looking directly at it

With those huge eyes, Zhao Bowen felt like he was looking into an abyss.

This photo is the result of the work of the astronomical team over the past month.

The astronomy team has undertaken the most important and most confusing task among the major expert groups, which is to analyze and determine the possible source of the black moon. The teacher's draft has pointed out the direction of the Milky Way. The black moon comes from the Milky Way, not the earth.

Born and raised, this is a crucial clue, and it is very reliable, as reliable as the teachers telling you before the exam that the exam scope is the entire book.

With such a clue, the astronomical team also felt that

After rigorous deduction, precise analysis, devout prayers to God and blind voting, everyone agreed that the most valuable target was the super giant black hole in the center of the Milky Way, so the long guns and short guns on the earth turned to focus their fire on the center of the Milky Way.

, don’t tell me, it’s really a bit of a gain.

They found that the fine shadow structure of Sagittarius A was different from what was expected. There may be interference from multiple gravitational sources outside the accretion disk. Further observations in the X-ray frequency band revealed that some of the energy was missing.

Although Zitai has repeatedly emphasized that this is entirely possible a natural phenomenon, after all, the universe is so vast and full of wonders, Zhao Bowen is already pounding the table excitedly: Black hole city! This is a black hole city! This is where the black moon comes from!

"Is this the latest result?"

Zhao Bowen calmed down.

"Old results, the study of supermassive black holes can be said to be a prominent science in the astronomical community. We have been working on it with our colleagues in Europe and America, including UCLA and the Max Planck Institute. In the first half of this year, the world's first

Do you want to take a photo of a black hole? They built an EHT called the Event Horizon Telescope, which also uses VL technology. It took a picture of the supermassive black hole of the M87 Virgo galaxy. The black hole is very big, with a mass of 6.5 billion times that of the sun. Their telescope

The virtual diameter is equivalent to the diameter of the Earth."

"Can we requisition them?" Zhao Bowen's first thought was this.

"Teacher Zhao, that's from abroad." Someone reminded in a low voice.

"Can we cooperate?" Zhao Bowen changed his words.

"We have cooperated." The reporter replied, "This observation plan has contacted EHT's eight radio telescopes. However, the time is too short and the plan is hasty. At present, we can only achieve this effect. After all, they are preparing to photograph the black hole of M87.

Ten years."

"We need to see more clearly." Zhao Bowen tapped his knuckles on the wooden table.

"It is possible, but you need to use a longer baseline and a longer observation time." The reporter on the stage said, "The results we have seen so far are from Beijing's LA-ST, Miyun, Shanghai Observatory and Australia

, the product of cooperation between several telescopes in North and South America, this cross-continental cooperation is already the largest baseline on earth. The baseline cannot be extended, only the observation time can be extended."

"We don't have ten years. After ten years, the day lilies will be cold." Zhao Bowen shook his head, "We can only make the telescope aperture larger."

Zhao Bowen pushed up his glasses, and he showed the excellent qualities of a Party A again: I don't care what you do, I just need you to do it.

But a telescope with an earth-diameter diameter is not enough. How can we build a telescope with a larger diameter?

"I can roughly understand what VL is going on. Multiple radio telescopes are networked to form a virtual large-aperture telescope. If we can move the telescope far enough, the aperture of the virtual telescope will be larger." Zhao Bowen said,

"Then let's use the revolution of the earth itself. The earth itself is rotating, and the movement of the earth itself can form a huge baseline. Ideally, the baseline can be as long as the diameter of the earth's revolution, which is almost two astronomical units."

Zhao Bowen added excitedly:

"This is similar to a telescope with an aperture as large as the Earth's orbit!"

"But VL needs simultaneity..."

Someone reminded me weakly.

"It is definitely difficult and requires technical research. I know that everyone can solve the problem." Zhao Bowen ignored the astronomy team's protest and opened the second folder, "Okay, let's start the second topic.

"

Zhao Bowen glanced down.

"How to capture the Voyager and Pioneer? If you have any ideas, please speak freely. If you have a plan, you can move forward."
Chapter completed!
