"Five...... Five million tons! How is this possible?! That extraterrestrial device is only that big, how can it have a mass of five million tons? Ye Luo, do you have a new BUG? After hearing Ye Luo's answer, Wei Feng's eyes immediately widened.

"No, Captain, I didn't have a bug." Ye Luo's tone of reply was still calm, "If you don't believe me, I can hand over this data to you, and you will calculate it yourself." It's incredible, but I have to say, it's all true. By the way, Captain, once again, I am talking about five million tons is the lower limit of the mass of this alien device, not its exact mass. Its mass can only be greater than five million tons, and it cannot be smaller than five million tons. As for how big it is...... Sorry, there isn't enough data to calculate and I can't tell you the answer. ”

Wei Feng fell silent. Because of the short hibernation time, Wei Feng's body was not much damaged. So at this moment, Wei Feng's head is very clear. But it is precisely because the head is clear that this result makes Wei Feng feel unacceptable.

The Star Ocean spacecraft is so big, what is its total mass? That alien device was only that big, how could it be dozens of times more massive than the entire Xinghai spacecraft? What material is it made of? What material has such a high density?

Thinking of this, Wei Feng immediately asked again, "What is the lower limit of its density?" What kind of material has such a high density among the materials we know? ”

Knowing the volume of this device and the lower limit of mass, it is very simple to calculate its lower limit of density. So Ye Luo immediately replied: "The lower limit of its density is seventy-six kilograms per cubic centimeter, which is about seventy-six thousand times the density of water." Among the materials known to us humans. No material has such a density. Not. As a contrast. The density of a white dwarf is about 1,000 kilograms per cubic centimeter, and although the density of a white dwarf is much higher than the lower limit of the density of the extraterrestrial device, it is still roughly considered to be of the same order of magnitude as the density of a white dwarf. ”

"How is this possible?" Wei Feng muttered, "Such a large density...... Isn't there an electron degeneracy pressure on this material that composes it? ”

When ordinary matter is compressed to a certain extent, the electron degeneracy pressure prevents it from shrinking further. Electron degenerate matter is usually found on white dwarfs and is created by the enormous gravitational pull of white dwarfs. If a piece of white dwarf material leaves the white dwarf, it loses a huge gravitational pressure. Then the white dwarf material will explode in an instant and return to normal matter. This is because of the pressure to degenerate.

Obviously, ordinary matter cannot have such a huge density, and it is even more obvious that this extraterrestrial device is not in a high-gravity environment like a white dwarf at this moment. According to common sense, it should be impossible to maintain such a state of existence. But that's how it exists, and the facts make Wei Feng have to believe this.

Then there is only one explanation left, this device has a very high technological content, and it is the unknown civilization that created it with unknown technology, so that it can maintain such a state of existence in a low-gravity environment.

It means a lot of things. First of all, the technology that can make this kind of thing must be very high. If you can get it, analyze how it's constructed. If human civilization is allowed to master this kind of technology, the technology of human civilization may make another leap, and it is not impossible to open that dead knot.

Its value is simply immeasurable. But the thing is very contradictory, its mass is too large, which means that it is impossible for Weifeng to capture it. It's like a poor man who sees a mountain of gold in front of him, but can't move it because he doesn't have the strength to do so.

It's a very frustrating thing. In the face of the cruel reality, Wei Feng had to give up the idea of capturing it.

But at this time, Ye Luo spoke again.

"Captain...... I've received some new data. These data ...... I don't know how to judge, so let's take a look. ”

"Oh?" Wei Feng was a little curious, so he got up from the hibernation pod and came to the display screen.

Wei Feng saw the image of the alien device in front of the display screen, but at the moment it was spinning rapidly. Its screw-like body was spinning itself wildly around a point in the nut area. And Weifeng can be sure that it did not rotate before.

Wei Feng was suddenly stunned.

"This is not the real image of the alien device, this is the data transmitted back by the sensors equipped on the four thrusters, and I did some processing of this data to construct this image through a model. If our data is correct, I believe that the true form of motion of the alien device at this point should be similar to what is shown in the picture. ”

"So...... Captain, can you understand the message conveyed in these images? Ye Luo asked faintly.

Wei Feng nodded and said, "I can understand. The fact that it began to spin itself conveyed two messages: one, it was not as technical as we had previously assumed. Two, we still have a chance to capture it. ”

"Yes." Ye Luo replied, "As long as the heaviest part of it is disassembled, we can get the rest of its instruments." ”

"That's a black hole...... A tiny black hole that is almost certainly artificially created. Wei Feng sighed, "Although our human civilization also has the ability to create miniature black holes in the laboratory, the time of their existence can only be calculated in Planck time. If we can obtain this miniature black hole, it will definitely play a great role in promoting the science and technology of our human civilization. But alas, it was so heavy that we didn't have the ability to catch it, so we had to throw it away and get the rest of it. ”

Wei Feng saw the screen of the instrument rotating and came to the conclusion that there was a black hole in it, which seemed very incoherent, but this conclusion was made after rigorous logical thinking.

There is a very simple truth, the greater the mass, the more difficult it is to change its state of motion. So, if the density of this instrument is indeed as high as speculated, then the propulsion of the four thrusters should not change any of its motion, what it was before, and what it will be. It didn't rotate before, and it doesn't rotate now.

But it now has a rotation, and it starts to rotate around a part of it. This means that the rest of its tectonic mass is actually very low, and that the vast majority of the mass of the lower 5 million tons is concentrated above its rotation point, and the connection between that rotation point and the extraterrestrial device determines that the device can only move without changing the distance.

What kind of motion is the state of motion without changing the distance? It's obviously a circular motion. Now, the extraterrestrial device's frantic rotation around the point of rotation is clearly in a circular motion as well.

Only when this is established can its state of motion at the moment be reasonably explained.

According to the part of the alien device that moves at this moment, the upper limit of the volume of the rotation point can be obtained. Divide the lower limit of mass by the upper limit of volume to get the lower limit of density of that heavy object. This is a very simple calculation process, just by doing mental calculations, Weifeng came up with the result: its lower density limit is ten tons per cubic centimeter. That's ten times the density of a typical white dwarf, but nowhere near the density of neutron star matter.

And this density is only the lower limit of its density, and its true density may be many times greater depending on the total mass and volume.

Whereas...... White dwarfs and neutron star matter cannot maintain such a dense state of existence after leaving the astral body and losing the constraints of massive gravity. Of course, the possibility of maintaining the state of existence by unknown technology cannot be ruled out here, but Wei Feng can be sure that that kind of technical means must be very superb, and it may not even be tens of thousands of years more advanced than human civilization at this moment.

Dense matter maintained by super technology is one possibility, and the other possibility is a dense state that does not need to be maintained by super technology. And the dense state that doesn't need super technology to maintain is only black holes. Obviously, a black hole with a mass equivalent to the sun is a black hole, a black hole with a mass of 1,000 tons is still a black hole, it is not like a white dwarf star and a neutron star, a white dwarf with the mass of the sun is a white dwarf, and a piece of white dwarf material with a mass of 1,000 tons will turn into ordinary matter.

So what exactly is the core weight has become a question of probability, one may be that the heavy object is a dense state of existence maintained by advanced technology, and the other may be that it is a miniature black hole. The technology content of miniature black holes is much lower than that of white dwarf or neutron star matter.

And based on the initial observations of this extraterrestrial device, such as through the exposed pipes, cables, passages, etc., it seems unlikely that it is so high-tech. This means that the probability of a "super-tech" is extremely low, and the probability of a miniature black hole is correspondingly high.

So, after seeing this alien device start to spin wildly under the propulsion of four thrusters, Wei Feng immediately came to the conclusion that "One, its technical content is not as high as we had speculated before. Two, we still have a chance to capture it", and believe that it has a miniature black hole in it.

Obviously, as long as he finds a way to throw away the black hole, Wei Feng can capture this alien device into his own hands. (To be continued......)
