Everyone: Are mechanics weak? I wake up and rectify the natural disaster

"As for the remaining Rota-6, and Zeta-1..."

“It cannot be said that there are no minerals in these two galaxies, but the mining costs are relatively high, and there are no special mineral veins with large reserves and high treasures.

When compared horizontally with other galaxies...there is no cost advantage. "

"On the contrary, it is because their host stars are special and have some characteristics that are conducive to energy production..."

Hipper finished showing the data and sat back in his chair.

Rota-6 is the three-body system galaxy with three b-type main sequence stars;

Zeta-1 is the only distant galaxy that is more than a hundred light-years away from the central galaxy and is not in the Rota Nebula.

Compared with several other inner ring galaxies, it is also somewhat special:

——Because the main star of Zeta-1 is a blue supergiant.

This is a different celestial body than a red supergiant.

The latter is the state of massive stars reaching the end of their lives.

But the blue super star...

Although it is also a special celestial body with an ancient age,

But usually they are not transformed from stars, but condensed from an entire nebula.

Blue supergiants are extremely large and extremely bright.

An ordinary blue supergiant is so large that it can fit thousands of yellow dwarf stars into its orbit.

As for its brightness, it is even more terrifying.

So much so that the huge thermal radiation will be like the plasma in the tokamak device, and all the ships passing through its close orbit will be like the inner wall of the reactor irradiated by the plasma, roasting it crispy on the outside and tender on the inside.

However, such a special existence also gives it considerable advantages in the field of energy collection:

If at a suitable distance, build a photovoltaic power station.

The surging energy that the corona of a blue supergiant can produce is much greater than that of an ordinary yellow dwarf or orange dwarf.

Of course, this also needs to be considered in the long term...

..

The Zeta Nebula, located more than a hundred light-years away, is much older than the Rota Nebula.

It was formed ten billion years ago.

Although both sides are in the same constellation, the Reticulus constellation.

But in this constellation covering thousands of light-years, there are countless lower-level celestial systems.

Totally too numerous to count.

Don't think that a group of stars with a diameter of only one or two thousand light-years looks small.

The outer edge of the Milky Way is only 80,000 light-years in diameter.

And that is a serious large galaxy, with more than 200 billion stars in it.

The Reticulum constellation can only be regarded as a secondary unit of secondary units under the Perseus galaxy.

But even so, there are at least tens of billions of stars in a star cluster.

The time period when the initial mass condensation was completed, the star-making movement began, and the main celestial bodies were born were also very different from each other.

It is normal for the ages of many intermediate celestial systems to differ by several billion years.

The blue supergiant star in Zeta-1 is one such example.

It was probably already collapsing from a nebula into a giant star when the yellow dwarf star in the central galaxy was just born.

So much so that to this day, its expanded size is already terrifying.

Using the sun as an analogy, it is about fifteen hundred times as big as the sun.

Except for it, almost all the primitive celestial bodies in the entire star system have been covered by its continuous expansion in their orbits, pulled by gravity, and finally fell into the blue sea of ​​fire.

When Hipper led the fleet to this strange galaxy, there was only a piece of scattered cosmic dust around the Zeta-1 main star, and a star with more than stars in a very, very far orbit. year cycle rate, the dwarf planet orbiting it.

That dwarf planet is not as big as Pluto.

It is estimated that it is only slightly larger than some giant asteroids.

It would take hundreds of thousands of years to complete one revolution, and it would be very difficult to see in the dusty interstellar dust.

Looking pitiful.

However, this is the only celestial body left in Zeta-1.

When Hipper scanned it, he felt relieved.

You must know that before this dwarf planet was scanned, she once thought that there was no planet here. The entire orbit was so empty that even the mice couldn't help crying when they looked out of the cabin.

"According to scanning readings, the intensity of the fusion reaction in the core of the Zeta 1 blue supergiant has not yet reached the rapid weakening stage.

Based on the current intensity of the reaction, its expected lifespan is at least 400 to 5 million years.

During this time, it will not suddenly explode as a supernova.

So we can use this star system quite safely instead of isolating it..."

Helena said.

The lifespan of celestial bodies is extremely long.

It's so long that one feels speechless.

The length of their lives is not at all on the same order of magnitude as the length of human life.

Supergiants are indeed the final stage of stellar evolution.

But people's life spans are measured in billions of years and tens of billions of years.

Judging from the expansion of the blue supergiant Zeta 1...

It is like an old coffin man who is seriously ill and dying soon. He is lying on the hospital bed with tubes inserted all over his body, and only his last breath is left to hang on.

But the flesh of such an old coffin is enough to support its existence for millions of years before it finally dies.

...In other words, the entire human civilization, and even the emergence of the human species, has only been less than four million years ago.

This kind of thing really makes no sense.

Even a fraction of this period is still hundreds of thousands of years away.

In these hundreds of thousands of years...if human beings had not developed into a higher civilization, they would have definitely become extinct.

As for four million years...

This is enough for mankind to develop into a super civilization.

If they could.

..

It is undoubtedly very unwise to use the time concept of intelligent life to measure the time concept of celestial bodies in the universe.

Except in extremely rare and coincidental circumstances.

Generally speaking, most ordinary civilizations that have not developed to the level of the Lost Empire do not have the opportunity to see the celestial bodies in their own land undergo morphological evolution as their life spans enter the next stage.

Therefore, Su Wen does not have to worry about the Zeta-1 star system being unable to be used.

“The biggest problem is that it is far away from the mainland of the empire and is isolated overseas.

Unlike other inner ring systems, it is relatively easy to control defensively. "

"It just so happens that it also has a hyperspace channel, which can quickly reach the central galaxy."

"So ... it becomes a defensive gap where we have to establish a strategic pivot."

The Fleet Commander, who currently serves as the First Main Fleet under the Ministry of National Defense, struck back and expressed her opinion,

"Come in, you can use this base to explore the Zeta Nebula and more distant star fields in the same direction;

If you retreat, you can also firmly hold this protrusion to prevent an enemy fleet from using this gap to raid the empire's mainland in the future. "

"To put it simply, the development of this star system must be put on the agenda as soon as possible."

Akashi shook his tail and said with a smile.

She likes this part the most.

Although developing new galaxies will add a lot of work pressure to the industrial production department she is in charge of.

But this feeling of slowly expanding and slowly farming.

But it is the most satisfying thing that can make a profiteer happy.

"Well, security issues are indeed something that cannot be ignored."

Su Wen glanced at the little cat subconsciously, feeling that this guy seemed to have some evil agenda.

But now is not the time to study the personal preferences of your subordinates.

Regarding the desire of government ministries to develop the Zeta-1 star system, he tentatively expressed his affirmation and support.

However, how to further formulate specific plans still requires continued discussion.

"Blue supergiants are not as dangerous as black holes and neutron stars, but they are not harmless objects either."

"Its optical radiation is very strong, so strong that it is not suitable for any ship to stay nearby."

Helena held a handheld terminal, opened the holographic projection, and introduced to everyone,

"If this blue supergiant existed in the solar system...

Then if it weren't for the sun itself, even as far as the orbit of Pluto, it would be completely swallowed up by it. All living planets here would be impossible to exist, let alone intelligent life such as human civilization. "
