Chapter Nine: Cave

"Ultrasound?" Mo Yu understood, "Did you perform a B ultrasound on it?"

The use of ultrasonic waves to probe the internal materials and structures is a common method, but this approach completely fails in the presence of a black sphere

"But it is indeed a ball," Mo Yu repeated for the third time

Having a great time

Liang Jing is a professional engaged in geology and structural physics. If a theoretical physicist were standing here now, he would most likely have already begun to take out paper, pen, and computer to calculate, attempting to find a black sphere constant to fit over the black sphere, ensuring that the existence of this sphere aligns with the current theoretical models

"But it is indeed a ball, how could it be a hole?" Mo Yu did not understand what Liang Jing meant, as this ball was right in front of everyone.

There is also Jiang Zi

"Do not concern yourself with whether it is allowed to exist; the issue is that it already exists, and this is an established fact. This ball was unearthed by you all." Mo Yu stepped forward, pointing at the black ball in the box, "Take a look for yourself; what else could it be if not a ball? Which do you believe more, our eyes or the theories in the books?"

Mo Yu was slightly taken aback; discussions at this level began to exceed her knowledge scope. Theoretically, the projection of a void in four-dimensional space onto the three-dimensional world is indeed spherical, but this is merely the result of calculations in mathematics and physics on paper. Ultimately, it is a conjecture, and no one has truly seen what four-dimensional space looks like

Both MRI and CT scans are ineffective, so can we only rely on ultrasound? Lou Qi said, "But it's not just ultrasound; C-scan, D-scan, E-F scan are all useless. It's like a mud ox sinking into the sea; even sound waves cannot escape this terrifying cage.

Mo Yu once again realized the crude nature underlying the high-tech facade of human technology. A single ball perplexed everyone, and all it did was remain silent, regardless of what you threw in, I would not respond.

"To call it a ball is less accurate than to call it a hole," Liang Jing suddenly said. "The X-rays and gamma rays we shot in may have already traveled to the other side of the Milky Way by now"

Mo Yu fell silent for a few seconds, and suddenly understood the rigid thought processes of these engineering and science men; if the observed reality contradicts existing theories, they will deny reality.

mechanical wave

Under the conditions within the Cassini station, Hu Donghai and his team found themselves at a loss, left only to stare helplessly.

The conservation of energy and thermodynamics are infallible

The experimental results are always just a coefficient away from the theoretical expectations

Mo Yu glanced at Director Hu beside him, who was leaning against the biosafety cabinet, standing there motionless, staring at the black sphere, seemingly lost in thought.

If it truly is a sphere, then its characteristic of swallowing without regurgitating would violate the laws of energy conservation and thermodynamics, thus it cannot be a sphere, Liang Jing explained

Jiang Zi is playing on his mobile phone

"In order to adhere to existing theories, can you physicists brazenly call a deer a horse and speak nonsense with your eyes wide open?" Mo Yu sighed in exasperation

If there is.

Ah? Oh, oh, oh, oh, yes, there is something. Mo Yu was momentarily stunned, then came to her senses and hurriedly nodded. If Hu Donghai hadn't reminded her, she would have almost forgotten the important matter. "The video! CCTV is urging us to shoot the video! We need to send New Year greetings to the people across the country! Everyone, go up, go up! The chef and Ya Xiang are still waiting up there!"

If this black ball is indeed a rigid body, without any deformation or distortion occurring, then mechanical waves cannot propagate within it at all

Mo Yu was taken aback

Nothing is unsolvable with a coefficient

"A hole in three-dimensional space is two-dimensional, specifically a circle, which is easy to understand. If a hole were to form in four-dimensional space, it would appear to us as three-dimensional, that is, a sphere." Liang Jing said, "Do you understand this? It looks like a sphere, but in essence, it could be a hole, merely a higher-dimensional hole."

"Let's pause here for now," said Director Hu, straightening up and adjusting his glasses. "Daydreaming will yield no results. We lack effective observation methods and need to gather more opinions from experts. Let's head up first, contact the Earth side, and report this matter... Also, Mo Yu, didn't you come to see us for a reason?"

The existence of black balls contradicts the principles of energy conservation and thermodynamics

Why is a standard sphere with a diameter of 10 centimeters referred to as a hole

"But it is indeed a sphere," Mo Yu asked, "How can it be a hole? A black hole?"

They do not even know whether the ultrasound was completely absorbed or simply failed to enter the interior of the sphere. If this black sphere is an indivisible rigid body, everyone knows that there are no true rigid bodies in the world. However, the appearance of the black sphere has shaken everyone's worldview. Before the emergence of the black sphere, people also believed that there was no standard sphere with a mass of e and a diameter of ten centimeters in the world.

Mo Yu did not immediately understand what this meant, but soon after, Lou Qi pushed the ultrasound contrast imaging equipment over.

However, even if this sphere were sent to Earth, the people on Earth would not necessarily have any effective means to analyze it. All they could do would be to use more sophisticated microscopes, employ shorter wavelength rays, and utilize higher energy particle beams. The black sphere has already proven that such methods are ineffective. According to human observational logic, they would never be able to gain insight into the internal structure of the sphere

That is merely because the coefficient is not large enough

"It is not just talking nonsense; you do not understand my point... A hole can also appear as a sphere." Liang Jing shook his protective suit and asked, "Let me ask you, if there is a hole in my clothing, what shape does it appear to be?"

Luo Qi stood across the way, furrowing his brow, appearing to be deep in thought. However, judging by his expression, he seemed to have no clue, as he looked as pained as someone suffering from constipation. Physics was not his field of expertise, and no matter how hard he tried, he was unlikely to come up with anything.

Thus, it is reality that is at fault

No, no, no, it is not a black hole. It cannot be a black hole if it truly has a Schwarzschild radius of 5 centimeters. Not to mention anything else, the mass of this sphere should be 2.25 x 10^25 kilograms, which is equivalent to 225 trillion tons, or about 3.75 times the weight of Earth. If its event horizon radius is much smaller than 5 centimeters, then it is impossible for any electromagnetic waves to escape. Liang Jing waved his hand, "I mean a proper hole, a hole in the ground." "I mean a proper hole, a hole in the ground."

When Liang Jing mentioned that this ball was a four-dimensional void, he did not speak, and his expression showed no change whatsoever. Perhaps Director Hu had already considered this point, but chose to remain silent.

Circle

Liang Jing's conjecture is quite bold, but I am afraid that even he himself cannot verify his own hypothesis

If it were a sphere, then it would violate the laws of energy conservation and thermodynamics, so it cannot be a sphere. Liang Jing also began to repeat, "The laws of energy conservation and thermodynamics would not permit its existence"

Of course, it is theory. Liang Jing was quite straightforward, without a moment's hesitation
