Galaxy Technology Empire

Seeing that everyone was about to return to the solar system in all directions, Ma Wu once again chose a direction and jumped back to the solar system step by step.

In fact, Explorer 4 can jump back in an instant. Level 4 civilization has almost no restrictions in the four-dimensional universe.

However, they still followed their original plan and stopped to investigate every 10 billion light years.

Ma Wu has been carrying out this kind of exploration work for hundreds of years, and he is so skilled in everything.

The star is still bright

The universe is still vast

The sea of ​​​​stars is bright along the way

life is everywhere

The Explorer records these civilizations and lives. There are many Level 3 peak civilizations in the River Galaxy Group, but Explorer 4, which traveled 560 billion light-years, did not discover the existence of a Level 4 civilization.

Of course, it is not ruled out that the other party does not want Ma Wu to know that if it is a fourth-level civilization that has mastered the technology of dimensionality lifting and lowering and particle robot technology, they can easily hide it.

"Captain, would you like some coffee?" Austin asked, holding up a simple ceramic cup.

Ma Wu shook his head: "Let's have a glass of cranberry juice!"

"OK." Austin snapped his fingers, and a glass of cranberry juice appeared out of thin air.

It's very sour, cranberry juice is more sour than lemon juice, but this acidity is just right for Ma Wu.

He took a sip of cranberry juice and flipped through Masayoshi Kobayashi's "Galaxy Odyssey 5", which involuntarily brought back his long-standing memory.

"Huh?"

Ma Wu turned his head: "What's wrong?"

Austin pointed to a large river galaxy group spanning about 600 million light years: "This galaxy group just showed a space jump signal."

Ma Wu put down his book and carefully looked through the radar records. Indeed, ten seconds ago, a short space jump signal appeared in the lower northeastern area of ​​​​the Dahe Galaxy Group.

"Qing Jiao, please track this signal."

"Leave it to me." Tatsucai Aokaku thought, and Explorer 4 immediately launched a hidden dark wave within more than 20 billion light-years nearby.

But what is puzzling is that they stayed at this location for three days, but the space jump signal never appeared again.

"Could he be passing by?" Ma Wu said.

"Could it be those bugs?" Austin thought for a while and said.

Ma Wu was noncommittal: "Don't worry about this matter for the time being, just record it, and we will continue to return to the alliance."

"Okay, kids, let's go home!" Aokaku Tatsu yelled.

Then Explorer 4 started the space jump device and jumped to the next tens of billions of light years away.

…

Not long after Explorer 4 left.

A spaceship appears at this location.

[Weak spatial fluctuations...]

[Confirm direction...continue tracking?]

[give up. ]

The spacecraft stayed nearby for a short while, then jumped away.

The void is still so calm.

It was as if nothing had happened.

Because neither the spacecraft nor Explorer 4 left any traces here, not even light reflections, only some weak signs of space fluctuations, which also disappeared into the void as the two parties left.

…

Continuous jumps, half a month later.

Explorer 4 came to a very empty area-the void of the universe.

Blue Star has existed for more than 4 billion years, but in the vast universe, human beings are actually very small. At the same time, the mysterious universe also brings endless fantasies and speculations to mankind.

According to the Big Bang theory, the universe was born in an explosion at a singularity.

After the explosion, the universe experienced a long period of expansion. At this time, all the stars had not yet formed, and what was formed was clouds of gas.

These gas clouds also gained gravity as they grew, and then gradually evolved into primitive stars.

The existence of cosmic voids is because in the early evolution of the universe, higher-density areas can form celestial bodies faster, and celestial bodies attract lower-density matter away through gravity, so that matter in originally low-density areas becomes Became even less.

Humans have discovered the existence of voids in the universe since the AD era. In 2015, scientists discovered a super-large void with a range of 1.8 billion light-years, which is 3 billion light-years away from the Blue Star.

The cosmic void and the cosmic Great Wall are the largest entities in the cosmic structure of the four-dimensional universe.

The largest cosmic void observed by the alliance spans 5.9 billion light-years and is a true dead zone.

"Captain, the maximum span of this hollow area is 2.4 billion light-years, and the minimum span is 860 million light-years, showing an oval shape." Austin Hui reported.

Ma Wu looked at the microwave radiation background map and star map. This radiation map is called the cosmic microwave background.

The cosmic void area has subtle temperature changes. Generally speaking, the microwave radiation temperature of the Great Wall of the Universe is slightly higher, while the microwave radiation temperature of the cosmic void is slightly lower.

On the cosmic microwave radiation background map, the void area is blue, while the Great Wall of the Universe is red.

Due to random variations in the expansion of the standard universe, a cold spot may appear as a one-fifth region.

According to the Alliance's parallel spacetime theory, the void cold spot is caused by a collision between our universe and another parallel universe.

Our universe exists in its own cosmic bubble, just like an atom, and countless other parallel four-dimensional universes exist simultaneously within the five-dimensional space-time.

Once two parallel universes collide, it may affect their respective interiors.

The existence of cosmic voids is closely related to other universes. If this view is accurate, then there must be countless parallel universes next to our universe.

"Check this cosmic void." Ma Wu is no stranger to cosmic voids. The Alliance has done a lot of research in this area.

"OK."

The dark wave scanned over, and there was no difference between the data and the alliance's data.

The fact that the universe is empty is just a small thought.

If two parallel spaces collide violently, it may even cause the death of all life in the two parallel spaces.

Using atoms as an example, a slight parallel space-time collision is equivalent to a chemical reaction of atoms, which at most results in the loss of some electrons; while a severe collision is equivalent to a nuclear reaction, which is very likely to destroy the integrity of the two parallel space-times.

Humans should be lucky that five-dimensional creatures did not use this universe as "nuclear fuel", otherwise humans would have been finished by now.

"Captain, there is an abnormal data."

"Tune it out."

Ma Wu browsed this data carefully, and the more he looked at it, the weirder it became.

Abnormal data shows that there are some strange planets in the center of this cosmic void. Originally, according to the characteristics of the void in the universe, these planets should not exist here.

"The age of the planet is generally around 37 to 40 billion years? How is this possible?" Ma Wu was confused.

The Alliance has long calculated the age of this universe, which is probably about 27.6 billion years ago.

"The data is not wrong. I have measured it three times." Austin curled his lips and replied.

"What's strange? Qingjiao."

"exist."

"Adjust the coordinates and target the ancient star cluster."

"almost done."

Explorer 4 opened the space door and instantly jumped to the vicinity of the super-aged ancient star.

"Austin takes another detailed measurement," Ma Wu ordered.

"OK."

The instruments of Explorer 4 started working, and these hundreds of ancient stars and their planets were scanned.
