Evolution from mushrooms

to his level.

A planet, this kind of area that only occupies less than 1% of the volume of the entire universe.

It is too small.

His range of activities must spread to the dark space of the universe, and even to the boundless dead zone between river systems.

And there, what Chen Mo currently lacks the most is substance.

Creep cannot be generated without matter.

There is no creep as a material backing.

Chen Mo couldn't display any skills.

He is still a creature of this universe after all.

It cannot be separated from the most basic laws of the universe.

So... are there civilizations in the current river system that are not affected by matter?

Chen Mo unfolds the bright star map.

Such a question was raised.

Soon, according to this doubt.

Bright Star Map gives the closest answer:

"Watcher Civilization."

090 can easily come to this conclusion by combining the intelligence of the entire river system.

Because of the construction site of the star gate, only the range of radiation was considered.

And whether it is convenient to extract the substance is not considered.

The closest galaxies around the stargate also have no missing matter.

Of course, some people may say that super civilizations can mine materials from other places.

Anyway, their energy is unlimited.

Transmitting matter through the star gate is a matter of convenience.

But Chen Mo can say with certainty:

There is no such thing.

You know, it has now occupied the entire river system!

Except for very few areas!

He has collected information on the entire river system and any (cabc) star system, but has not found any information on large-scale collection of materials.

The star gate is extremely huge.

The material to be collected is an astronomical number.

There will definitely be batches of star systems that will be eliminated collectively.

Chen Mo has calculated that this will leave at least tens of thousands of "bare suns".

That is:

Only the middle is worthless, and only light elements are stars (stars usually only contain lighter elements such as hydrogen and helium).

But such galaxies are rare in the entire Milky Way.

Even if there was, Chen Mo did a targeted investigation.

It was discovered that their original planets were all moved away by other level 2 civilizations, or the entire star system reached an old age, and the stars expanded and swallowed up the rest of the planets.

Of course, level 3 civilization can disguise the matter of moving materials.

In the entire river system, it is easy to conceal this kind of thing.

However, this is not at all.

A level 3 civilization "Star Capital" is placed there in a big way.

Instead, it hides traces of the excavated material.

This is totally impossible.

So there is only one answer.

The Guardian civilization is capable of birthing matter out of thin air.

Based on Chen Mo's current knowledge analysis.

There are two technical paths to choose from for the Guardian civilization.

first technique,

It is the direct conversion of energy into matter (mass).

Matter can be converted into energy, and energy can naturally be converted into matter.

This process is reversible.

Currently Chen Mo has observed this manifestation in two places.

The first place is in the particle collider of the titanium mechanical civilization that he occupies.

After improvements, the laboratory is now capable of photon collisions.

That is, the "photon" collider.

When two photons collide, electrons and positrons are produced.

The other is something that all Level 2 civilizations can observe: black holes.

No matter how much energy goes in, it will be converted into the mass of the black hole.

Black holes can be regarded as natural "energy-matter converters".

Some civilizations have imagined "drawing" matter from black holes.

However, for a level 2 civilization, how to approach the black hole without any damage is a big problem.

The second option,

It is the extraction of elementary particles from the vacuum to make up matter.

Regarding this technique, Chen Mo has also observed examples.

And it is obviously more feasible than the first technology.

Especially with a 'zero point engine'. .
