On one side is the deep sea of the Earth's Pacific Ocean.
On one side is the edge of the solar system several hundred astronomical units away.
A door connects the two spaces.
Chen Yu stood at this end of the portal, picked up the second rock, paused for a moment, and threw it into the space membrane.
In just twenty seconds, the rock with a diameter of more than 30 centimeters spun and disappeared, falling into the terrifying darkness...
"The direction is right, the black hole is not far ahead."
Taking off his hand armor again, Chen Yu glanced at his watch and sent a private message: "The institute sent the second calculation result. The gravity acceleration of the rock falling is 2.2 meters per second, and the distance from the black hole is within 150,000 kilometers. There’s also some acceleration here that I push out.”
"So… "
Putting down his watch, Chen Yu looked at the camera: "Keep moving forward."
"One hundred thousand kilometers!"
Amid the dense barrages in the five live broadcast rooms, Chen Yu calibrated the virtual projection direction and advanced the portal to within 20,000 kilometers of the black hole.
The prompt of successful docking sounded, and he immediately took out a rock with a diameter of one meter and threw it into the darkness inside the portal.
This time, the rocks "falled" extremely fast! In just three or four seconds, he disappeared from the sight of Chen Yu and the audience.
[Fuck! Gone?]
[Isn’t the acceleration too scary?]
[It’s nothing to be afraid of, it’s not a big black hole. After all, it is only more than a hundred times the mass of the earth.]
[It is clear that disaster is imminent, but I always want to call 666...]
[Same as above.]
[The existence of black holes can now be determined, otherwise with this kind of acceleration, it would be impossible not to see the surface of the planet.]
[Why didn’t the gravity of the black hole suck away the anchor at the other end of the portal?]
[Please re-watch the host’s first live broadcast video.]
[The deposit is 300,000. If the UP master cannot save mankind, I will take my family to enjoy it.]
[When the whole world is in chaos, can you still enjoy it? Air tickets booked.]
[I have sold the house. (Smile)]
[Calm down, please...]
…
In aerospace institutes, scientific researchers are getting more and more data, and their calculation results are becoming more and more accurate.
"The mass is 7.45625000E+26, the acceleration due to gravity is 20.72 seconds..."
"Forty-nine thousand kilometers!"
"Forty-nine thousand kilometers!"
"I am here too."
The old dean got the data and immediately forwarded it: "Mr. Wang, the distance between you and the black hole is only 49,000 kilometers."
…
Inside the island-building project ship, Chen Yu received the message and showed his watch screen in front of the camera: "There are 49,000 kilometers left, and the direction is correct."
"This distance is already very close, approximately equivalent to a little more than one circle around the Earth's equator."
"Because the flight speed of my protective suit is in vacuum, which is at least one thousand meters per second, which is much greater than the escape speed at this distance, so I should be able to move forward a little."
"Keep moving forward! Twenty thousand kilometers!"
[… farewell.]
[farewell.]
[farewell.]
[farewell.]
Operating the portal "advanced" 20,000 kilometers.
Inside the door, it was still pitch black. There is a lack of reference objects, as if the distance in space has not been shortened at all.
"Whoosh—"
The fourth rock flew in and disappeared in the blink of an eye...
The calculation results from the Aerospace Research Institute came again.
"The rock accelerates at 59.16 meters per second and is 29,000 kilometers away from the black hole."
After confirming the distance, Chen Yu stretched out his hand to slide the virtual projection and explained casually: "There are less than 30,000 kilometers left. If the Earth is nearby, the terrifying tidal force will tear the Earth apart instantly. On the scale of the universe, it is really already We are close at hand. Then move on..."
"Twenty thousand kilometers!"
With the twisting and turning of space for the fifth time, the portal suddenly lit up with orange light.
This represents the first level of warning.
The space membrane was torn apart by strong gravity...
"There are three levels of warnings for portals in the star system, orange light, red light and black light. If it reaches red, it means extremely dangerous, and black means that space connection cannot be established. So don't be too nervous about the current orange warning."
With that said, Chen Yu picked up the fifth rock and threw it into the dark depths.
moment.
The rock disappears.
The speed of being sucked in far exceeds the upper limit of human dynamic vision.
Taking a step back subconsciously, Chen Yu looked at the camera: "Can you calculate the flying speed of the rock? And how far away is the black hole and me?"
Ten seconds later, a reply from the institute came through the private message interface: "I'm very sorry, Mr. Wang, the video recorded by your camera was received by us. There is not much information retained. If it is slowed down to a certain extent, it will be blurred, making it impossible to accurately calculate the gravity of the rock. Accelerate. Can you come to the institute and take away a group of experts and professional equipment?"
After seeing the reply, Chen Yu hesitated for a while and nodded: "Okay, I'll go now."
After saying that, he collected the current space coordinates and turned to the aerospace institute in the capital.
In the square inside the door, there were already a dozen scientific researchers waiting in the cold wind, holding various tools, equipment, and notebooks, shivering.
"Europe!"
"coming!"
"Come in quickly, the lithium battery cannot be frozen."
"Bring the high tripod! Hurry..."
More than a dozen scientific researchers swarmed in. They didn't even have time to say hello to Chen Yu, and they were busy setting up high frame rate cameras and various computing equipment.
Everyone's face turned red with excitement.
Will the earth be destroyed or not
Will mankind be extinct
Does the universe exist
In their eyes, do you have a close relationship with them? !
Black hole!
This is a black hole!
Or a primordial black hole that can be observed at close range!
Just getting the gravitational acceleration data at different distances is a revolutionary breakthrough in the world of physics...
"Wang...Mr. Wang, we are ready." A person in charge held the weighed rock and walked to Chen Yu, suppressing his excitement.
"good."
After taking the rock, Chen Yu said nothing, walked to the portal, adjusted the spatial coordinates, and threw the rock under the focus of the suspended camera and high frame rate equipment.
"Whoosh—"
The rock disappeared into the darkness, not even a trace of light appeared...
"Beep!"
The ultra-high frame rate camera buzzed, and the researchers immediately exported the video data and performed intense calculations.
"The acceleration of gravity is 593.65 meters per second, a=GM/r... 6.6726 multiplied by ten to the negative tenth power Mm/kg... "
"M=5.965×ten to the twenty-fourth power kg times 125..."
"The results are out!"
A middle-aged researcher jumped up and shouted excitedly: "The distance to the black hole is 9,154,730 meters! It's accurate!"
"The mass of the black hole is also accurate." Another researcher breathed quickly: "7.45625331E+26!"
"The escape velocity is also found. At a distance of 9154730 meters, the escape velocity is 104255.92 meters per second."
"One hundred thousand meters per second?!" Chen Yu was suddenly stunned: "Doesn't it mean that I can't escape if I go in?"
Hearing this, many scientific researchers were stunned for a moment, and then a woman quickly explained: "Mr. Wang, that's not the case. You have fallen into the misunderstanding of escape velocity. Escape velocity means that when you reach this speed, you can throw out without power. No power. ! As long as the thrust continues, you can fly out slowly even if you are far from reaching this speed. As long as your flying speed is greater than the falling speed."
"I see."
Chen Yu suddenly realized, and then said: "Then we should be able to move forward, right?"
"Yes, yes, yes!" ×14
All the researchers nodded like chickens pecking at rice, staring at Chen Yu with shining eyes.
"That… "
Chen Yu vaguely felt something was wrong, but he still bit the bullet and said, "Keep going, how many kilometers is appropriate?"
"Let's go another five thousand kilometers!"
"Would...would it be too much?"
"No." The middle-aged researcher stepped forward and patted his chest: "Please absolutely believe us!"
Chen Yu: "..."
…
(Note: All data are calculated personally based on the mass of the black hole. Every 0.1 has been calculated many times to ensure authenticity. Thanks to the two book friends for their "brain power" and "computing power" support. I hope it is not wrong 2333... )
