Super Battleship Reborn

Looking at the stars all over the sky, the scientists were all silent and thinking nervously.

I have an idea. A scientist of the No. 75 race stood up and said nervously: In our current theoretical system, our big universe is limited but boundless. Then, we Can you think that this small universe torn from the big universe has the same structure, limited but boundless?

What does this mean? Xiao Yu asked back, while gesturing to it with encouraging eyes.

In fact, Xiao Yu knew very well what the scientist was going to say, and so did Xiao Yu's thoughts, but Xiao Yu did not express his thoughts. When appropriate, it is also important to cultivate the way of thinking of these scientists. Anyway, a false name doesn't matter to Xiao Yu, Xiao Yu is happy to hand over the honor to these scientists, so that they can work for him more attentively.

Encouraged by Xiao Yu, the scientist seemed to be more confident. It saluted Xiao Yu, and then said: First of all, we know that light travels through space, and the curvature of space also bends light. After reaching the edge of the universe Afterwards, the light will go back the same way. Therefore, I have a speculation that all the stars in this small universe are the same one.

Xiao Yu nodded slightly. The scientist's thinking is exactly the same as his own.

There was a lot of discussion in the conference room, some scientists expressed their support and some expressed their opposition.

Let's discuss the possibility of this speculation. Xiao Yu said, waving the arm manipulating his phantom, and sent a command, and the three-dimensional projection equipment projected two mirrors between Xiao Yu's hands .

These two mirrors are very ordinary, no different from the mirrors made by humans in the earth age. Two mirrors stand facing each other, immediately. Infinite phantoms appeared in the two mirrors, extending to the infinite distance of nothingness, endless, with no end in sight.

This phenomenon is very common, and it is easy to reproduce this scene in human society in the earth age. Xiao Yu even did this kind of experiment when he was a child, that is, take two mirrors and let them look at each other . Then there will be an infinitely extended image in each mirror. This is because the light is reflected back and forth between the two mirrors. First, mirror a shines on mirror b, and there is an image of mirror b in mirror a, and then mirror b reflects the image of mirror a and the image of mirror a. It is reflected again, and then the a mirror shines on the b mirror... every time the light is reflected. The number of such phantoms will increase by one, more and more. up to infinity.

This scientist's point of view. It's the same as the infinite phantom that will appear when two mirrors look at each other. Xiao Yu pointed to the phenomenon that appeared in the two mirrors and said, This phenomenon can probably explain why what we are seeing now In this small universe where we live, there are so many stars with exactly the same data in terms of spectrum, volume, mass, density, etc. The reason is very simple, they are all the same star in the first place. It’s just that its light has passed through the edge of the universe infinitely many times reflection, so it looks like there are so many stars.

All the scientists showed a look of sudden enlightenment. As junior fifth-level players, they can easily understand every reaction in this process.

Because it is in Xiao Yu's existing theoretical system. The universe is finite but infinite. Just like a two-dimensional plane universe, curl it into a three-dimensional world sphere, and the creatures in the two-dimensional universe live on the surface of this sphere, so it is easy to understand the sentence of finite but boundless, because obviously, these two-dimensional Creatures, no matter from which point to which direction, no matter how far they travel, they can't find the boundary of this universe, and at best they return to the origin.

same,

A three-dimensional world, seen from a four-dimensional perspective, is also a sphere, but a four-dimensional sphere. It is still limited, but it has no boundary. The light propagates in the three-dimensional space, and it is impossible to break through this three-dimensional universe, at most, it is to return to the origin.

So that's a good explanation. The light of a white dwarf starts from the white dwarf and then spreads in the three-dimensional world, perhaps because of the difference between the four-dimensional world and the three-dimensional world, it does not return to the origin after returning, but appears in another position . Then, from the eyes of the living beings in this universe, there is one more star in the starry sky of the universe. Then its light continues to spread and returns again, and it looks like there is another star... After countless reversals and deflections, the current situation is formed. It seems that there are countless stars that are exactly the same in the universe. of stars.

It's like an infinite phantom reflected by two mirrors facing each other.

At the same time, it is also easy to explain why this phenomenon does not occur in the large universe of the real world. Because the light will continue to weaken during the propagation process, and it is likely to be too weak to be observed when it is transmitted from one side of the universe to the other. Another point is that the scope of the big universe is so vast that even light takes more than 10 billion years to reach the edge, and the universe has only been born for 13.7 billion years. .

So it is impossible for such a situation to appear in the macrocosm, and only in such a microcosm can such a phenomenon occur.

But one thing needs to be pointed out. This is just our speculation. Xiao Yu said, We just found an explanation, but we can't verify this explanation. Smart No. 1 has made it very clear that we only have one chance. Once If you make a mistake, there is no possibility of recovery. Now, I need a way to verify this conjecture. And there is another point, even if our conjecture is verified to be correct, how can we eliminate the ghost and find out the truth? It's still a tough question.

Because obviously, since only one of these stars is an entity, and the rest are phantoms, the hiding place of Smart One must be the real star. But... how to find this real star among the countless phantoms around it?

We have the ability to verify this conjecture, and at the same time, we can also find this real star. Luca No. 3 said, Actually, there are some mistakes in your statement, master. Each of these infinite stars is not a fiction. Shadows, each a substance, yet they are still the same.

This statement seems to be a bit contradictory. In this cosmic starry sky, there are more than one billion stars currently observed. Each of them is an entity, that is, one billion stars, but they are the same one, one billion and one, the gap between them is so huge, it seems that there is no way to connect these two numbers.

All the scientists looked at Luca III, waiting for it to continue.

Actually, it's easy to explain. Luca-3 said, Because no matter which star we choose and approach, we will eventually be transported to the same place in this three-dimensional world that is curled into a four-dimensional sphere. It is next to this real star. So this test is actually not difficult at all. Choose one of the billion stars and approach it at random, and we will come to the real target position. I think, what Smart One said We only have one chance, and the words we have to choose carefully are nothing more than putting psychological pressure on us to make us dare not choose lightly.

After listening to Luca III's statement, the conference room fell into silence again. Scientists are all thinking hard, including Xiao Yu is also thinking.

After being silent for a while, Xiao Yu said: This statement is very reasonable. Our existing theoretical system fully supports this statement, and it can perfectly explain what we are currently encountering. But... there is one more thing, we How to verify this conjecture? Well... very good, very good, this conjecture is actually very easy to verify.

Luka No. 3 looked at Xiao Yu's phantom with a smile on his face, and nodded: It's really easy to verify.

At this moment, there are still some scientists who have not figured it out and are still confused, looking at the two in confusion. Xiao Yu explained: Since the three-dimensional universe is a closed sphere in the four-dimensional world, no matter which way we sail, we will eventually return to the original point, so let's just sail once and see if we will return to the original point. place. Anyway, before the verification results come out, we will not approach any stars, so this is not a violation of the rules.

That's it. Lucca-3 continued: Actually, if it is just to verify the deflection of light and explain why there are so many stars, we only need to launch a powerful artificial sun, and then observe whether there are any stars in the universe. The rest of the powerful artificial suns will be enough. But in order to verify the statement that every star is an entity, it is best to go on a long-distance voyage in person, so that the data obtained will be more complete and more credible.

Okay. An artificial sun has been launched, and it can last for half a month. Well... If our calculations are correct, the diameter of this small universe is only 30 to 40 billion kilometers. According to the speed of light, we Within three days at the latest, another phantom will appear in the universe. If there is a phantom, we will sail to this phantom to see if we can reach this artificial sun in the end next to...

This is my whole plan. Xiao Yu said, If it can be reached, then the first test will be easily passed. If it cannot be reached, it will prove that we are wrong, and we will think of other ways .”
