This is indeed a very large space for the shape of a hanging hemisphere. Pen fun and pavilion www.biquge.info

Against the backdrop of a tiny sky overhead, the entire huge space seemed even more empty.

It's really empty, so empty that everyone can see everything in the entire dome space at a glance.

"It's so simple, it's not the same as the alien super civilization I imagined!"

Durunik looked at the huge circular platform in front of him, and the lone diamond-shaped console on top of the platform, and was very surprised.

"[The Source of Creation] should not be a spaceship of a super alien civilization, and a real spaceship must not be so simple." Frank looked around and judged based on all the information he had said before, "The [Source of Creation] was designed to be just a spark of life, so from the perspective of resource conservation, except for the necessary equipment, other equipment is estimated to have been reduced. ”

"It's a pity that this cut has made us miss out on a lot of super tech ......"

"At least there are artificial gravity systems, as well as power systems, but I don't know if they can still work after 2.1 billion years of time." Although Frank's tone was calm, his heart was full of anxiety and worry, after all, these only remaining alien technologies were related to the technological leap of human beings on Earth.

"Although we can't be sure of the working condition of the power system for the time being, the artificial gravity system is definitely fine, and we have all learned its power." As soon as Yuan Haochen finished speaking, except for Durunik, everyone present had a wry smile on their faces.

"Let's go ahead and have a preliminary inspection, everyone should pay attention to protecting all the instruments and equipment, and no one should tamper or disassemble any equipment and devices before they are completely sure." Frank ordered solemnly.

As a result, the crowd began to scatter around the dome space for carpet inspections.

Everyone divided their work areas, and then prepared to inspect the surrounding "suspicious areas" first, and after figuring out the overall structure of the [Source of Creation], they would explore the core area.

This is not Earth after all, and there are really not many people who can be called up on Mars.

Therefore, even with the use of the most advanced detection equipment, everyone's exploration is still very slow. But this is a matter that cannot be rushed, slow work, about that.

"Drip~Drip~"

"Buzz~Buzz~"

In every corner, Yuan Haochen had to use a precision X-ray scanner, an infrared thermal energy scanner, and a laser spectrum analyzer to conduct a detailed inspection.

With the deepening of the inspection, Yuan Haochen also began to slowly and initially get in touch with and understand the construction technology and material use of the [Source of Creation].

As far as the main material of the entire dome space is concerned, this alien civilization chooses a synthetic material with low density but extremely high strength.

Due to the lack of professional testing equipment, data indicators such as toughness, corrosion resistance, stiffness, and temperature resistance cannot be obtained for the time being.

The space environment is harsh and complex, so the standards and scales for the selection of aerospace materials are the highest in all industries.

In the current field of geoscience and technology, the progress of space materials depends on the following key factors:

First, new discoveries in materials science theories, such as the directional arrangement of rigid molecular chains in polymer materials, have led to the development of high-strength, high-modulus aramid organic fibers.

Second, the progress of material processing technology, such as: directional solidification technology, precision forging technology, composite reinforced fiber layup design and process technology development, ultra-fine powder manufacturing technology, etc.

Third, the progress of material performance testing and non-destructive testing technology.

Aerospace materials can be divided into aero engine materials, rocket and missile materials and spacecraft materials according to the different objects used in the materials.

Many parts manufactured by aerospace materials often need to work under extreme conditions such as ultra-high temperature, ultra-low temperature, high vacuum, high stress, and strong corrosion, and some are limited by weight and accommodating space, and need to play an equivalent function under normal circumstances with the smallest volume and mass, and some need to operate in the atmosphere or outer space for a long time, and it is impossible to stop for inspection or replacement of parts, so they must have extremely high reliability and quality assurance.

In the manufacture of space vehicles, the selection of materials with light materials, high strength and good stiffness can reduce the structural weight of the space vehicle itself, which means increasing the carrying capacity, improving the maneuverability, increasing the flight distance or range, and reducing the consumption of fuel or propellant.

The Starship spacecraft uses a special titanium alloy as the main material of the spacecraft.

Because titanium alloy has the advantages of high strength, low density, good mechanical properties, high toughness and corrosion resistance. However, the process performance of titanium alloy is poor, the wear resistance is poor, and the production process is complex. Cutting is difficult, and in hot processing, it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen, and carbon.

The interior of the Starship spacecraft uses structural materials with advanced properties and functional composite materials with electrical, optical, thermal and magnetic properties.

"It seems that this synthetic material is very different from the titanium alloy of the starship spaceship...... "Yuan Haochen thought as he scanned and analyzed the elemental composition of the synthetic material.

After preliminary elemental scanning analysis, this synthetic material mainly contains 13 constituent elements, including 6 metallic elements and 7 non-metallic elements.

In terms of the types of elements, there is not much difference from the materials used on the earth, which is also a good verification that the types of elements in the universe are common.

For nearly 100 years, our scientists have discovered more than a hundred basic metallic and non-metallic substances in space.

Among them, 94 species exist on the earth, and other elements that cannot be found in the earth's nature can be synthesized in the laboratory, but substances with atomic number greater than 83 (that is, the elements after bismuth) are very unstable and will undergo radiative decay.

Therefore, Yuan Haochen guessed that the advanced technology contained in the high-strength materials of this alien civilization must be related to the molecular (atomic) structure technology. For example, nanotechnology on Earth can greatly improve the properties and applications of materials by locating the size of the studied structures in the range of 1 nanometer to 100 nanometers.

"Maybe the alien doctors, their technology can study the structure of materials to the size of the nanometer accurately, maybe picometers and femtomi." Yuan Haochen secretly guessed various possibilities in his heart. (1 m = 10^9 nm = 10^12 picometers = 10^15 femtometers)

According to Hara's guess, this alien civilization may have mastered the material technology of the picometer and femtomi level, and even the relative ultimate goal of material technology - directly using atoms or molecules to construct materials with specific functions.
