According to Rodriguez, the mass of the black hole in the base is about 100 million tons. According to Schwarzschild's formula, the radius of the event horizon of such a black hole is only about 1.5 times 10 to the minus 16th power. For comparison, the radius of a proton is about 8.5 times 10 to the minus 16th power, which means that the size of a black hole with a mass of 100 million tons is about one-sixth the size of a proton.

This is already the category of the microcosm, and it is naturally impossible for the human eye to see. No matter how large its gravitational pull is, according to the gravitational formula, the gravitational force after leaving it has shrunk dramatically to about 7,000 times that of the Earth's gravity, and this number is difficult to cause changes in light that are visible to the naked eye.

So this black hole is actually invisible. But at this moment, Rodriguez said again, "I have a way for you to see it", which can't help but make Zhao Lan feel strange.

But after a while, Zhao Lan instantly understood again, "Hmm, Rodriguez is probably going to feed the black hole." ”

Black holes are invisible, and they cannot be seen except by their impact on the surrounding space and matter. Its impact on the surrounding space is generally divided into three aspects, one is gravitational lensing, the second is to attract the surrounding stars to revolve around itself, and the third is to eat.

If the telescope sees a distorted image of a river system in the sky, or observes two identical river systems at the same time, then one can probably know that a black hole passed between the river system and the Earth, and used its gravity to distort the light transmitted by the river system to the Earth, which is why that strange phenomenon appeared on the Earth. This is the gravitational lensing phenomenon. And if one observes a star or a neutron star or something like a star revolving around an invisible point, then one probably knows that there is a black hole there. And if there is a sudden burst of extremely strong gamma rays and X-rays in a certain place, then people can probably know that there is a hungry black hole that is frantically devouring the surrounding matter.

These three phenomena can be used to mark the existence of black holes. Therefore, although people cannot see black holes directly, they can still be found through various phenomena. However, it is clear that the small black hole in the base cannot be marked by gravitational lensing or star rotation. Then there is only one last possibility, which is to mark the existence of the black hole through its feeding.

"Miss Zhao Lan, you are the first scientist outside the base where you can actually see a black hole feeding." Rodriguez said with a smile on his face. "Today is the day when our base helps government research institutes deal with hazardous waste, and about a ton of hazardous waste is going to be put into a black hole, and you can watch the whole process."

"Really......?" Zhao Lan felt faintly excited in his heart.

"Yes." Rodriguez nodded, "The government used to deal with these hazardous wastes. The price is about 5,000 per gram of waste, and the company set up by the boss is offering 1,000 humans per gram of waste. We've saved the government four-fifths of its waste disposal money. And all we need to do is ...... It's as simple as throwing them into a black hole. ”

Zhao Lan couldn't help but shook his head in disbelief. For every gram of 1,000 human coins, one ton is a billion human coins...... That's enough to buy your own Sylvia.

One billion human coins are a wealth that ordinary people cannot accumulate without eating or drinking in their lives, and they are scientists. But all his monthly income adds up to only a little more than 10,000 human coins, if it weren't for the government's special award, for the sake of his ancestor Zhao Huasheng's face, he gave himself a spaceship, and he would never think that he could afford a private spaceship in his life. And for Li Yunfan's base, one billion human coins is as simple as feeding a ton of hazardous waste to a black hole.

"This ...... It's also a little too easy to make money. Zhao Lan thought silently, "No wonder Li Yunfan can accumulate so much money in a short period of time." ”

"Look...... They're already getting started. Rodriguez said, pointing to another display screen.

So Zhao Lan saw several staff members wearing full-body protective clothing operating a forklift-like machine and placing a large box that was tightly sealed on a conveyor belt. The conveyor belt kept turning, transporting the box deep into a machine.

"This machine is the gateway to the black hole. Black holes are too dangerous, and to prevent the unexpected, everyone. All matter, with the exception of this conveyor belt, is not allowed to go near the black hole. Rodriguez introduced, "Look...... It has been subjected to electric field treatment, and the instrument that binds the black hole will control its movement through electric field bondage, and accurately drop it into the black hole. ”

Through another monitor, Zhao Lan saw that the big iron box wrapped in the black hole began to expand slowly at this moment, from two meters to about eight meters before stopping. A hole was opened on top of it, half a meter long and wide.

"Before the box was opened, the glass cover was already in a vacuum, so there was no need to worry about the black hole accidentally ingesting." Rodriguez said.

Zhao Lan nodded. If there is not a vacuum in the glass cover. The black hole will first absorb the air around itself, and then under the action of air pressure, the air from other parts will continue to converge towards the black hole until the black hole finally sucks up all the air in the glass enclosure. And if there is an intercommunication between the glass cover and the base. The black hole will then suck up the air throughout the base. And if this base is connected to the natural environment...... Then this black hole will stay here and still, and it will one day be able to suck the entire atmosphere of the Earth into itself. Of course, the most likely scenario is that after the black hole has absorbed a certain amount of air and increased its mass to a certain point, the electric field-bound instruments can no longer support it to hang in the air, and it will fall directly. Then it penetrates everything to the center of the earth, and eventually swallows the whole earth.

The box containing hazardous waste finally appeared inside the glass enclosure, and then suspended in the air and began to slowly fall towards the black hole. As it fell, a number on the display kept jumping and expanding, and Zhao Lan knew that the number showed the magnitude of the black hole's gravity on this sealed box at the moment.

When it came to the gap in the iron box where the black hole was bound, the gravitational reading was 1/37. The distance is five meters, that is, at a distance of five meters, the gravitational pull of the black hole is one-thirty-seventh of the Earth's gravity.

When the distance is reduced to three meters, the gravitational pull of the black hole is about one-thirteenth of the Earth's gravity.

When the distance is reduced to one meter, the gravitational pull of the black hole is about two-thirds of the Earth's.

Combined with the gravitational pull of the Earth itself, it is already subjected to nearly twice the gravitational pull of the Earth. But twice the Earth's gravity doesn't have any effect on the material of the sealed box.

As its distance from the black hole gets shorter and shorter, it shortens to a distance of only two decimeters...... Something strange happened. This black hole can be approximated as a particle, while this box is a macroscopic object, and it cannot be seen as a particle. So there must be a gap in the distance between its different parts and the black hole. Just like now, its center is only two decimeters away from the black hole, but its edge is about 5.8 decimeters away from the black hole. This creates a huge gravitational gap, with a pressure of 17 times the Earth's gravity at a distance of two decimeters from the black hole, and only twice the Earth's gravitational pull at its edge.

So the center of the sealed box began to bulge towards the black hole, and the further it went to the edge, the smaller the bulge. As the electric field control instrument controlled it closer and closer to the black hole, the center of the sealed box bulged more and more until it was only four centimeters away...... The bulge was pulled by the gravitational pull of more than 400 times the earth, and it finally broke. So a thin strip stretched out from the top of the sealed box to the invisible black hole, and when the matter was only a centimeter away from the black hole, the gravitational force had risen to 6,800 times the gravitational pull of the earth, when the distance was reduced to only one millimeter, the gravitational force was 680,000 times that of the earth's gravity, and when the distance was reduced to only a tenth of a millimeter, the figure was 68 million times...... And this number has already exceeded the gravitational strength of neutron stars.

So the whole box was torn apart. It was pulled into a long strip by the black hole, and began to rotate wildly around the black hole, and in the process of rotation, it was gradually swallowed by the black hole into its own body. The matter collided as it swirled, and an extremely bright visible light was emitted, dazzling in the pitch-black box. Zhao Lan knew that this was only what he saw, and in the band where he couldn't see, there were still a large amount of gamma rays and radiation in other bands being released.

This process lasted for a while, and then all the matter was swallowed up by the black hole, and then darkness and silence returned to the box. As high as one ton, the hazardous waste that required human civilization to pay a billion human coins to dispose of was easily swallowed up by the black hole, completely and completely disappeared from the visible universe.
