The start of science and technology - Chapter 280
“Is that why you were attacked?” Du Xingyu asked green pupa.
“Almost,” said the green pupa, “our butterfly civilization doesn’t want to join any camp, so after coming to the galaxy, we have been looking for ways to preserve civilization.”
“At the beginning, we tried to create an independent space to wrap our civilization.”
“Independent space is your star system wrapped in four-dimensional bubbles?” asked tours.
“Yes. But we failed.” green pupa did not shy away from their failure. He said: “whether our four-level civilization uses cutting space or four-dimensional barrier to build space, it is not called independent space at all!”
“In simple terms, it’s like drawing a circle on a two-dimensional plane, which is still in the two-dimensional world.”
“Only by mastering the advanced civilization of dimensional technology can we build a real independent space, that is, the so-called small universe technology!”
“You go on, what happened after the butterfly civilization failed to build an independent space?” Lu Xing is very interested in the butterfly civilization, because human civilization is also facing the same problems as the butterfly civilization.
The green pupa then said, “helpless, we thought of leaving the Milky way.”
“We sent star class warships to explore the surrounding River galaxies. Soon we found that there was no so-called civilized hunting ground in the large and Magellanic galaxies near the Milky way.”
At the same time, the artificial intelligence Ruby opened the star map.
The Magellanic galaxy, also known as the little Magellanic nebula, is located in the constellation Rhododendron, 200000 light-years away from the Milky way, with about hundreds of millions of stars.
The Large Magellanic galaxy is only 163000 light-years away from the Milky way, one fifth the diameter of the Milky way, and has about 20 billion stars.
Their mass is much smaller than that of the Milky way.
“There is no civilized hunting ground in the Magellanic Galaxy?” Du Xingyu was thinking about the green pupa. If this information is accurate, there are several possibilities.
First, the civilized hunting ground in these galaxies has not been opened. Second, these galaxies are too small and do not have enough civilization. It may also be that the civilized hunting ground in these galaxies has ended, and so on.
“We decided to transfer the whole civilization to the Large Magellanic galaxy, which is relatively rich in resources. It took 10000 years for our civilization to slow down in the last river migration!” said the green pupa. “So in order to prepare for this migration, we built a free civilization market and collected a lot of resources.”
“We have created a wormhole in a river Galaxy spanning hundreds of thousands of light-years to achieve the purpose of civilization migration!”
“A wormhole spanning hundreds of thousands of light-years!” everyone was surprised by the wormhole he described. Human civilization has built wormholes. Naturally, we know how difficult it is.
The wormholes of human civilization span hundreds of light-years, and the resources consumed are already very difficult. What they built is actually a wormhole that can span the Milky way!
Just think about it, you will know how much resources and efforts butterfly civilization has spent to build this wormhole in the river system Galaxy!
“Then why didn’t you leave the galaxy?” Chen Hong guessed. “Your wormhole was found?”
“Commander Chen guessed right.” green pupa said with a bitter smile.
“In fact, the butterfly civilization has long been targeted by the civilizations of the two camps. They can get a lot of benefits by hunting the fourth level civilization.”
“Twenty years ago, we closed the free civilization market and prepared the whole civilization to leave the galaxy. But at this time, a level 4 civilization in the angel civilization camp attacked us, forcing us to temporarily close the wormhole and be forced to fight!”
Green pupa shows a picture to human commanders. It is a familiar starry sky, butterfly star cluster.
In the butterfly cluster, tens of billions of warships and spacecraft are busy flying. They are carrying materials and preparing to leave the galaxy.
In a secret space of the butterfly cluster, the star mother tree of butterfly civilization spent many years of energy to open a wormhole that can be connected to the Large Magellanic galaxy.
Outside the wormhole, hyperspace fluctuations suddenly appear.
“Warning, this is the territory of butterfly civilization. You have entered the military control zone, please leave immediately!” while warning, butterfly civilization commanded the warship to lock the place of hyperspace fluctuation.
After a few seconds, an object gradually emerged.
It is a neutron star with very strong density and mass. Its size is less than the volume of those star class warships, but as soon as it appears, the surrounding space-time is immediately affected and distorted by its gravity.
“A neutron star, through hyperspace transition?” Yang Shaolin was stunned. How much gravity is the neutron star?
At the end of the evolution process of stars with different masses, there are many forms, such as white dwarfs, pulsating variable stars, neutron stars and black holes.
White dwarfs are evolved from medium mass stars with great mass and density.
Humans have used the explosion of new stars on the surface of white dwarfs to annihilate the main fleet of Eagle civilization.
Neutron stars are the most dense stars in the universe except black holes!
The density of neutron stars is 8 ^ 14 ~ 10 ^ 15 grams per cubic centimeter, which is equivalent to more than 100 million tons per cubic centimeter [1]. This density, that is, the density of the nucleus, is 100 trillion times the density of water.
Compared with the tens of tons of cubic centimeters of white dwarfs, the latter seems insignificant. If the earth is compressed like this, the diameter of the earth will be only 22 meters!
In fact, the density of neutron stars is so large that the mass of neutron stars with a radius of 10 kilometers is equivalent to that of the sun.
At this time, the enemy of butterfly civilization actually took the neutron star as a weapon and made a hyperspace transition.
“Attack!” no matter who the enemy is, the fleet of butterfly civilization has begun to attack.
This is the core area of their civilization.
However, the attack of butterfly civilization on this neutron star with huge density and mass is like tickling.
On the surface of the neutron star, its gravity collapses all matter, and even the nucleus no longer exists!
Electrons are compressed into the nucleus and neutralized with protons into neutrons, so that the atom becomes only composed of neutrons. Neutron compression supports the neutron star and prevents it from further compression.
The whole neutron star is formed by such nuclei close together. It can be said that a neutron star is a huge atomic nucleus!
The density of neutron stars is the density of atomic nuclei. The mass of neutron stars is so large that the huge gravity makes the light break away in a parabola. It has shown the ability of some black holes!
The neutron star locked the target and hit the star river fleet of butterfly civilization.
Butterfly civilization has been operating for thousands of years, with rich family wealth. The performance of Xinghe class warships is powerful, and the number is much more than that of human civilization.
They use various gravity weapons and space weapons to attack neutron stars.
