Chapter 836 A small universe with a diameter of one light year

[The captured stars can be placed in the civilization microcosm and used by the star energy extraction device. ]

These are the original words of the fortress master [Ten].

From this sentence, it can be seen that the seventh-level civilization [Tenth Empire] has at least one microcosm of its own.

At first, when he learned the news, Lv Yongchang found it difficult to imagine such a scene.

What kind of technology should a civilization master to "create" a microcosm.

Yes, "create".

Lv Yongchang, who was still in the fifth-level civilization and had only a preliminary understanding of the theory of space and time, once believed that this so-called "microcosm" was created directly out of thin air using technologies such as the Big Bang.

This caused a great shock to Lv Yongchang at the time.

Of course, it was limited to that time.

As human civilization's understanding of space and time gradually deepened, Lv Yongchang had a vague guess about the [microcosm].

Due to the lack of observational and experimental data, it can only remain at the level of guessing.

Until today.

He looked at the dim space without any starlight in the holographic projection, and inspiration continued to gush out of his quantum brain.

Through the various data sent back by the detection ships and detectors, he constantly confirmed his original conjectures about the [microcosm].

Wrong conjectures were eliminated, and correct conclusions were retained...

At some point, a deep blue holographic projection had unfolded in front of him.

The projection was full of formulas and models based on the theory of space and time.

At this moment, apart from the holographic projection full of formulas in front of him, Lu Yongchang only had the rapidly flashing detection data.

The command work was temporarily taken over by Fang Xu.

Under Fang Xu's command, Zero began to control a large number of detection ships and detectors to conduct a comprehensive detection of this suspected microcosm space.

First, humans need to figure out its boundaries.

In other words, how big is it.

Time passed slowly.

The holographic projections in front of Lu Yongchang were stacked layer by layer, and the continuous calculations made Lu Yongchang's face show a little fatigue.

But his eyes became brighter and brighter.

The original doubts and haze were slowly disappearing bit by bit.

At the same time, Zero's detection of the microcosm was gradually coming to an end.

The simple model of the small universe was gradually improved and projected into the holographic projection.

This is a standard spherical space.

The diameter is about one light year.

Not big.

It is even smaller than the solar system - with the Oort Cloud as the boundary of the solar system, its radius is about one light year.

But even so, this small universe still made the faces of the academicians present show joy and excitement.

…

The biggest difficulty in the cross-galactic expedition is actually the problem of material reserves.

Antimatter fuel is nothing.

The biggest part is actually the maintenance materials and starship replacement parts.

After a long journey of 5,000 years, various parts in the starship will inevitably be damaged.

Although the engineering ship can carry out comprehensive repairs on the damaged starship in real time, it requires resources after all!

In the galaxy, these resources are not a big deal.

For a level 6 civilization, it can obtain the required materials by going to the nearest star system with the curvature engine.

But if it is between galaxies...

This is completely different!

That is an area with extremely sparse matter.

That is a vacuum close to the extreme, and the density of matter is even measured by the number of atoms in a unit space.

Even the so-called galaxy bridge is just a small road with a relatively higher density of matter, which is not comparable to the density of matter in the Milky Way!

For the seventh-level civilization that has mastered the technology of mutual conversion of matter and energy, the neutral hydrogen bridge is a perfect route - they can directly spend a considerable amount of time collecting these hydrogen atoms and convert them into pure energy, and then convert the energy into the required matter.

But for human civilization, which is still at the sixth level.

The neutral hydrogen bridge is just a fuel replenishment area that adds icing on the cake.

It can't provide any matter other than hydrogen.

Therefore, the biggest problem facing human civilization has emerged.

In addition to fuel, the fleet also needs to carry enough various supplies, but the more supplies it carries, the more fuel it consumes, and the larger the fleet it needs.

The larger the fleet, the more spare supplies and parts it needs to carry, and the fuel consumption...

"Forward cycle" belongs to it.

Relying on the huge computing power of Zero, the Academy of Sciences once conducted a comprehensive simulation of the entire route and found a relatively suitable navigation plan.

According to that plan, when the human fleet leaves the Milky Way, it will be a huge fleet with more than 20,000 starships.

And when it arrives at the Andromeda Galaxy, the fleet size will drop sharply to more than 3,000 ships.

This is a terrifying drop.

What? Where did all those starships go?

After the supplies inside are consumed, these starships themselves will be dismantled and used.

They have never disappeared, but just changed the way they accompany human civilization.

...

That's why, when they learned about the diameter of this small universe, all the academicians had an idea in their minds.

How much supplies can be loaded in a small universe with a diameter of one light year?

If you can take this small universe with you on an expedition, does human civilization still need to worry about insufficient supplies during the expedition?

What? Insufficient fuel?

Just learn from the mother star fortress left by the [Tenth Empire] and put two stars in it!

Insufficient supplies?

We already have stars, so it is normal to put a few more planets in it, right?

As for the fleet...

Just park the fleet in the small universe and release it when we reach the destination.

Zero loss in the true sense.

In other words, since we already have stars and planets, it is normal for me to build some more starship factories, right?

Since we already have factories, it is reasonable to build a few more research institutes, right?

During the long journey of the Milky Way, humans can even develop quietly in the small universe for five thousand years!

"Start with a small universe, survive until the ninth level civilization and then come out again"

Of course, the above are all imagined pictures in the minds of academicians.

Ideals are beautiful, but reality is cruel.

Today's human civilization currently has almost zero knowledge of this small universe.

The reason for its appearance, whether it is stable, how to move...

It can be said that we know nothing about it.

Not to mention taking the small universe on an expedition, we don't even have the ability to move stars into the small universe.

Of course, the cruel reality did not hit these academicians. On the contrary, when they learned about the size of the microcosm, their enthusiasm for scientific research instantly soared!

Let me ask, who can resist the temptation of carrying a microcosm with them and developing science and technology?
