Super Battleship Reborn

Looking at the stars, scientists are silent and thinking nervously.

"I have an idea." A scientist of the seventy-fifth race stood up and said a little nervously: "In our existing 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 in return, and at the same time he gestured it with encouragement.

In fact, Xiao Yu knew exactly what the scientist was going to say, and Xiao Yu's idea was the same, but Xiao Yu didn't say what he thought. At the right time, it is also important to cultivate the thinking style of these scientists. Anyway, stigma does not matter to Xiao Yu. Xiao Yu is happy to give honors to these scientists, so that they can work harder for themselves.

Encouraged by Xiao Yu, the scientist seemed to have a lot of self-confidence. He gave a gift to Xiao Yu, and then said, "First of all, we know that light relies on space to propagate, and the curvature of space will also make it bend. When it reaches the edge of the universe After that, the light will return the same way. So I have a speculation that in this small universe, all the stars are the same. "

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

There was a lot of discussion in the conference room. Some scientists expressed support and some opposed it.

"Let's discuss the possibility of this speculation." Xiao Yu said, waving his arm that manipulated his ghost, sent a command, and the 3D stereo projection device projected two mirrors between Xiao Yu's hands. .

These two mirrors are very ordinary, and there is no difference between the mirrors made by humans in the earth era. The two mirrors stood opposite each other, immediately. Infinite virtual shadows appeared in both mirrors, extending to the infinite infinity, infinite, without seeing the end.

This phenomenon is very common, and it is easy to reproduce this scene in the human society in the earth era. Xiao Yu, a young boy, also did such an experiment, that is, take two mirrors and let them face each other. . Then an infinitely long image appears in each mirror. This is because the light is reflected back and forth between the two mirrors. First, the a mirror hits the b mirror, and the a mirror has the image of the b mirror. Then the b mirror reflects the image of the a mirror and the image of the a mirror. It shines again, and then the a mirror hits the b mirror ... every time the light is reflected. The number of such ghost images will increase by one, more and more. All the way to infinity.

"This scientist's point of view. It's the same as two mirrors facing each other and there will be infinite virtual shadows." Xiao Yu pointed to the phenomenon appearing in these two mirrors and said, "This phenomenon can probably explain why we are now In this small universe, there are so many stars that are exactly the same in terms of spectrum, volume, mass, density and other data. The reason is very simple. They were originally the same star. However, its light has passed 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 realization. As elementary and fifth-tier families, they can easily understand every reaction in this process.

Because in Xiao Yu's existing theoretical system. The universe is finite but boundless. Just like a two-dimensional flat universe, curl it into a three-dimensional world sphere, and the creatures of the two-dimensional universe live on the surface of the sphere, so it is easy to understand the limited but boundless phrase, because it is clear that these two-dimensional Creature, no matter what direction and direction they sailed, no matter how far they sailed, they couldn't find the boundary of the universe, at most they returned to the origin.

Similarly, a three-dimensional world, from a four-dimensional perspective, is also a sphere, but just a four-dimensional sphere. It is still limited, but has no boundaries, and light spreads in three-dimensional space, and it is impossible to break out of this three-dimensional universe, at most it is to return to the origin.

Then it is very easy to explain. The light of a white dwarf starts from this white dwarf and 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 location . From the perspective of the creatures in this universe, there is an extra star in the universe starry sky. Then its light continued to propagate and returned again, and it looked like there was another star ... After numerous inversions and deflections, it has formed the current situation. It seems that there are countless identical ones in the universe Stars.

It is like an infinite virtual image reflected by two mirrors facing each other.

At the same time, it is well explained why this phenomenon does not occur in the real universe. Because the light will continue to weaken in the process of propagation, it is likely that the attenuation from the side of the universe to the other side is too weak to be observed. Another point is that the scope of the big universe is too wide. Even the light takes more than 10 billion years to reach the edge, and the universe has only been 13.7 billion years since its birth. .

Therefore, it is impossible for such a scene to appear in the big universe. Only in such a micro universe can there be such a phenomenon.

"But there is a point to point out, this is just a speculation for us." Xiao Yu said, "We just found an explanation, but we couldn't verify it. Smart One said it very clearly, we only have one chance. Once If there is a mistake, there is no possibility of recovery. So now, I need a way to verify this speculation. And there is another point, even if we verify that our speculation is correct, how can we eliminate the ghost and find out the truth? This Still a tricky issue. "

Because it is clear that since only one of these stars is an entity and the rest are ghost images, the hiding place of Intelligent One must be the real star. But ... how can I find this real star among the countless surrounding shadows?

"We have the ability to verify this speculation, and at the same time, we can also find this real star." Luca III said, "Actually, there are some mistakes in your statement, master. Each of these infinite stars is not false. Shadow, each one is an entity, but they are still the same. "

This statement seems a bit contradictory. In this cosmic starry sky, the number of stars observed so far alone exceeds one billion. Each of them is an entity, that is, one billion stars, but they are the same one, one billion and one. How big the gap is, and it seems that there is no way to link these two numbers.

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

"It's actually very easy to explain," Luca III said, "because no matter which star we choose and approach, we will eventually be transported to the same place in this three-dimensional world curled into a four-dimensional sphere. It's right next to this real star. So this test is not difficult at all. Just choose one of these billion stars, and we will come to the real target. I think what Smart One said We only have one chance to choose words carefully, it is just putting psychological pressure on us and making us dare not choose easily. "

After hearing Luka III's statement, the meeting room fell silent again. Scientists are thinking hard, including Xiao Yu.

After being silent for a while, Xiao Yu said, "This statement makes sense. Our existing theoretical system is very supportive of this statement, and it can perfectly explain what we are currently experiencing. But ... one more thing, we How to verify this speculation? Well ... very good, this speculation is actually very well verified ~ www.wuxiaspot.com ~ Luca III looked at Xiao Yu's ghost with a smile and nodded : "It's really good to verify. "

At this moment, there are still some scientists who still don't want to understand. They are still confused and staring at them. Xiao Yu explained: "Since the three-dimensional universe is a closed sphere in the four-dimensional world, we will eventually return to the origin no matter which side we sail to, then we should simply sail once and see if we will return to the original Place. We wo n’t be close to any star until the verification results come out, which is not a violation of the rules. "

"That's it." Luka III continued: "In fact, if we just want to verify the deflection of the light and explain why there are so many stars, we only need to launch a powerful artificial sun, and then observe whether the universe is The rest of the powerful artificial sun will appear. However, in order to verify that every star is a physical entity, it is best to sail for yourself, so that the data obtained is more complete and reliable. "

"Okay. An artificial sun has been launched and it can last for half a month. Well ... if we calculate correctly, the diameter of this small universe is only 30 to 40 billion kilometers. According to the speed of light, we In the latest three days, we will see another ghost image appearing in the universe. If a ghost image really appears, we will sail to this ghost image and see if we can finally reach this artificial sun. Next to ... "

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