Abnormal crossing

Chapter 111 Look what I found? (Part )
The gray-brown rocky plain stretches to the horizon, with tens of thousands of weathered soil piles distributed in a honeycomb pattern.

The streamlined aircraft flew rapidly between the rolling hills, and the airflow kicked up dust and trailed a spiral trail behind it, as if it was wearing a sand-colored cloak.

"It's so desolate." Looking at the repetitive background of dirt hills, Gu Wei couldn't help scratching his hair. "Mee-mee, isn't it said that the planets in the Lanqiao Galaxy will capture garbage through gravity? It seems that the density is not very high now."

"That's true, but you also have to consider the position of the planet," Mee Mee, who was sitting in the front and seemed to be driving the aircraft with both hands but was actually controlling it remotely, adjusted her glasses and explained, "Generally, planets that rotate left to the deepest areas will have a high load of garbage on their surfaces. This T8097 has only been sent into the galaxy for less than years. In Jin's words, it is still pink and tender after just being in the sea."

"In addition, most of the node planets have been simply transformed, and the garbage will be preferentially attracted to certain areas to form garbage dumps, so you will certainly not easily see waste on the surface."

Hearing this, Gu Wei touched the armrest of the aircraft.

Also.

Planets with a high scrap coverage rate must have many people who like to pick up bargains. After devouring Chokoven's information, the Eraser should have gained consciousness to some extent, and the place it chooses to "digest" the information must be as remote as possible.

"Oh right," Gu Wei then thought of something else: "Meimei, you said these planets have been transformed?"

Meow Meow nodded: "That's right."

"Wouldn't the cost be very high?" Gu Wei had a questioning look on his face. "Instead of spending money on these changes, why not just use a giant device like a super-large crusher to process the garbage? Or just put it into a star and burn it."

Gu Wei has actually been curious about this question for a long time.

The number of stars in a medium-sized galaxy can easily start at hundreds of billions. If you want to deal with garbage, can't you just throw it on the stars and burn it?
Theoretically, except for a few items like Boruto, most stars should be able to function as incinerators, right?
But the Star Alliance chose to empty the entire galaxy, build a hub and fill it with artificial planets. Doesn't it seem a bit unnecessary?
"The cost is very high?" Hearing what Gu Wei said, Mee Mee shook her head like a little adult: "Typical planetary thinking, to put it bluntly, it's just taking things for granted - do you think it's easy to use a star as an incinerator?"

“临近行星需要的技术暂且不提，光是前往恒星需要的能量就夸张到了极点——每运送1吨垃圾至恒星的同步轨道平均需要消耗1.2×10^12焦耳能量，相当于300吨标准煤完全燃烧释放的热能，如果不走轨道直接冲过去也行——用1%光速运送1吨垃圾，单程能耗差不多要4×10^18焦耳，比前者多六个量级。”

"In the starry sky, there is a term called celestial energy return rate for this kind of scenario. The energy return rate of the stellar burning scheme is always less than 0.01. Even the return rate of the near-Earth orbit plasma gasification technology is more than times that."

"However, the method of directly transforming the Blue Bridge Galaxy into a garbage dump is different. The biggest expense is the cost of vacating the galaxy before completion. After that, it only requires some simple transformation of the planet's surface based on the left-hand rotation of celestial bodies. It is a bit like a dam or canal in planetary civilization. Once it is built, it will be a one-time thing."

Meow Meow glanced at Gu Wei as she spoke.

Gu Wei's situation is actually very common in the starry sky. Many planetary life forms come into contact with starry sky civilization by chance, and they usually have the idea that this kind of starry sky energy seems to be inexhaustible.

There is actually nothing wrong with this kind of thinking for individuals. For example, the energy generated by one flight of the Flutter Flutter is enough for all mankind on Earth to use for seven or eight years.

But if we change it to the level of the sea of stars, this idea actually has a serious deviation.

In any civilization at any time, the most energy-efficient method is always to combine technology with nature - such as the ancient waterwheel, the Three Gorges Dam before Gu Wei traveled through time, and the gravity slingshot, etc.
The same is true for the Blue Bridge Galaxy. The cost of vacating an entire galaxy is staggeringly high. It is a cosmic-level project, and the total energy consumption is about 1.7×10^54 joules. (Note: I have calculated it, and there are pictures to prove it. I used the supercomputer of the Academy of Sciences)

But just like the Zhengguo Canal and the Three Gorges Dam on Earth, this is an expenditure that will benefit generations to come, and it can even be said to be a lifeline project for a civilization!

"."

After being given some quick refresher lessons by Mee Mee, Gu Wei stopped asking questions and stood behind the protective shield, waiting quietly.

After a few minutes.

The air waves below the aircraft slightly retracted, and it stopped steadily somewhere in the southern hemisphere of the planet: "We're here."

Gu Wei didn't open the hatch, but followed Milo's example and climbed out of the car. He looked to the right and said, "Oh my god. This is in line with the style of the painting."

I only see this moment.

About a few hundred meters away from him, there stood a three or four hundred meter high mountain of waste. The bottom layer was a dense metal bedrock formed after more than ten years of gravity sedimentation, which was stacked with super-compressed metal modules.

Dark red iron oxide seeps into the cracks in the titanium alloy, forming a rather spectacular rust waterfall.

The middle section was cluttered with all kinds of items, like a single dog's bedroom. There were crooked, upside-down aircraft wreckage, tattered cargo spaceship cargo hold shells, and a large piece of condensed blue-purple ice on the far left.
As for the top of the waste mountain, it is relatively simple, with small objects such as metal skeletons and robotic arms piled up on top of a small hill.

At the very top was a metal robot head similar to Arnold from the Terminator. Its side seemed to have been burned by some hot weapon. Its head looked pointy, and its dull pupils showed that its internal structure was completely empty.

all in all.

This is in line with the painting style that Gu Wei wanted at the beginning.
When Gu Wei landed, Mee Mee also floated down. He came to Gu Wei leisurely and said, "There are two piles of waste on the left, right and front. Where do we start?"

"They're all the same, let's just go to the left," Gu Wei casually picked the direction he used most often and liked the most, then raised his head and looked at the waste mountain: "By the way, Meimei, how should we start picking up trash for the first time?"

There were many large objects in the mountain of waste in front of him. Even the most common metal heads were estimated to be heavy. Calculated at five kilograms per head, Gu Wei asked himself if he had the physical strength to carry only four or five for a distance.
"Oh, that's easy."

Hearing this, MeeMee waved her hand, and a device similar to a medical box on Earth floated out from the seat: "Here, carry this thing first."
