Such a vast universe.

Not to mention that there is no existence that can reach the speed of light. Even if there is, to cross such a long distance, it would take 'billion years' as the unit of travel.

The Tianjue continued to shuttle through the wormhole.

A wormhole is even closer than a shortcut in the traditional sense. It directly connects two unrelated spaces.

But even with such a shuttle, the Tianjue still sailed in the vast universe for 35 days.

During this period, every time a wormhole was used up, a new time halberd would return, bringing with it a wormhole with a wider range. The sixth and seventh halberds all returned like timely rain.

Everyone has the same expectations and goals.

It is to reach the 'endless universe' beyond the edge of the universe, to help Brother Liu find Gu Fan, and to put a perfect end to his own journey in the universe.

And Liu brother.

It always transforms into different ethereal forms and sails around the Tianjue.

Occasionally.

Above the Tianjue, you can see Liu Di’s vague face.

Slowly, his eyes were no longer confused, but became as deep as the starry sky.

Like a god above the hustle and bustle of the world.

universe.

How big is it and how is it defined.

Of course, humans have not explored the entire universe, let alone observed the entire universe.

The so-called "observable universe" is actually an algorithm that is calculated with the help of changes in the light bands, radiation energy, ultraviolet bands, and infrared bands of celestial bodies.

The age of the universe should be about 13.72 billion years.

The area of ​​the universe is a sphere with the earth as the center and a radius of 46.5 billion light years.

So according to this inference, the universe is a disk? About this information.

Brother Liu once held a helpless and self-deprecating attitude.

The earth is a tiny speck of dust among the countless stars in the universe.

Human beings are an ordinary group among the countless lives in the universe.

But to summarize the entire universe with oneself as the center is somewhat self-aggrandizing.

Brother Liu has no intention of despising his own homeland, nor does he underestimate the achievements of countless human astronomers.

only.

The universe is so vast, how can we be arbitrary?

But with recent voyages, the outlines of the universe have become clearer.

Liu Di felt like he was slapped in the face.

According to current judgment, the universe is truly a circle, not an ellipse, not a square, and not an irregular dispersion.

In addition, there is another thing, which is the periodic table of chemical elements in junior high school textbooks. Those 118 elements actually encompass the universe.

Brother Liu felt as if he were in a dream.

Are humans so powerful? As a 0.7 level civilization, they are the center of the universe and can understand the composition of all matter?

Or... there is some unknown connection hidden behind this.

Why did Liu Di infer that the universe is round.

Because the route of Tianjue's voyage this time is based on the Earth, it is completely straight, heading all the way west, directly to the 'end of the universe'.

now.

The Tianjue has traveled 46.45555 billion light years and is only "a finger's breadth" away from the theoretical "edge of the universe."

Of course, this "one finger" refers to the scale of the entire universe, and the actual distance is still hundreds of light years.

The surrounding scene at this time can be described in four words - no one's land.

It is dark and deep here, and the light is extremely weak, almost non-existent.

Moreover, within a range of hundreds of light years, no decent celestial body was encountered, only some large pieces of debris were seen sporadically.

According to the theory of cosmic expansion, this piece of the universe has just emerged and does not have a complete ecosystem at all. Even slightly larger celestial bodies have not yet condensed into shape.

As for stars and life, it is even more impossible for them to exist.

Young Liu exclaimed in the bridge, "Has no one ever arrived here?"

Liu Di's voice rang in Liu Xiaodi's ears, "If you have such thoughts, then others will have them too."

Brother Liu, who was diffused in the vacuum, felt something in his heart and looked forward.

But I saw thousands of huge golden starships floating quietly in front of me.

Brother Liu sees things clearly.

Those starships were made of the most advanced alloys in the universe, and the assembly process was almost flawless. The appearance of those warships looked like ceramic works of art placed in the sun.

Brother Liu obtained their information instantly.

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

Jasper civilization, level 10 technological civilization.

The crew of the Tianjue are ready to fight. Is there another blind man preparing to block their way?

but.

Liu Di and the Tianjue sailed slowly and calmly past the Jasper fleet.

Brother Liu knows.

The Jasper civilization is just a technological civilization that is motivated to explore the limits of the universe, not arrogant and domineering.

and.

When it comes to the level of ten civilization, both technological means and racial wisdom have reached a certain height.

Unprovoked fighting and bullying are completely outside their scope of action.

From the outside, the Jasper civilization was just quietly observing the Tianjue.

But Brother Liu could hear it.

The creatures inside them were very stunned and discussed.

"For a starship this small, with incomplete supplies and equipment, it is hard to imagine how they managed to travel all these billions of light years."

"Do they have the huge financial resources to support countless star gates?"

"Moreover, it seems that this small starship will continue to sail?"

"I'm afraid what lies ahead is beyond its ability to resist."

"Even our Jasper civilization has stopped here."

The two forces passed each other and lived in peace.

The Tianjue continued sailing and after entering a wormhole, Jasper, a level 10 technological civilization, was left far behind and disappeared.

When the Tianjue sailed out of the wormhole again.

It's already 20 light years away.

The universe here is lonelier, darker and quieter.

It was almost a pure vacuum, and even small pieces of gravel could not be found.

But everyone, including Liu Di, had a strange feeling.

It feels like I can't perceive the passage of time.

For example, Brother Liu.

He was standing on the bridge and suddenly came to his senses. He didn't know whether he had been standing there for 10 minutes or 10 hours. He had no clear idea at all.

The white-haired peach looked at the peach pit in his hand in despair - Oh, this big peach, when did I eat it? Kunsang carried his baseball bat and kept one leg forward - Uh, what was I going to do just now?

The little bottle cap looked at the plant in his hand, somewhat puzzled - when did it bloom? Hmm? When did it bear fruit? Hmm? Why did it wither? The Tianjue was sailing quietly.

Because the outside scenery was pitch black and there were no reference points, no one knew whether the Tianjue was sailing or stationary.
