Voyage of the Stars

"Before that, we were using long-distance communication based on quantum entanglement."

? ? ?

What?

While everyone was still confused, they heard the rhombus crystal continue to say: "In fact, after a billion years of hard work, some of our scientists have even thought that cosmic civilization is just an illusion, a level that seems feasible but can never be broken through. Because we have never seen a cosmic-level civilization, until one day, our quantum long-distance communication suddenly failed."

"Ah? You mean quantum over-distance communication? What does the failure of over-distance communication mean?" Liu Miyan asked blankly, thinking he heard wrongly.

But he didn't want the rhombus crystal to reply: "That's what you said, quantum super communication, a method of communication that uses the quantum entanglement effect to achieve long-distance and real-time communication. Quantum super-distance communication was originally used between me and other 'drifting bottles' The communication between me and my civilization and the communication with other "drift bottles" was interrupted, and it has not been restored until now. So now I don't know how our civilization So, where are you? Did you successfully reach your destination? Have you mastered the new method of long-distance communication?

I don’t know anything about anything that will happen next to my civilization except that it knows for sure what it means when quantum telecom fails. However, I am absolutely sure that there is nothing wrong with the function of quantum long-distance communication in my program. It is the universe that has changed.

In my information records, it should be the time when the ‘Bottle Project’ had just been completed and the Great Voyage had just begun. When my civilization set sail, it used the most primitive electromagnetic waves to store this information in our information storage device, and then resolutely led countless civilizations on the great voyage. "

In the past, we used quantum long-distance communication!

Previously, the ghostly effects of quantum entanglement could be used for long-distance communication!

Unexplained sounds echoed in everyone's minds, and they knew they had heard a huge secret.

For a moment, people who knew the significance of this news were really shocked, beyond shock.

According to the rhombus crystal, previous civilizations used quantum long-distance communication, but it suddenly failed, but it has not been restored to this day.

What does this mean?

It means that the physical laws of the universe have changed. The physical rules of the universe cannot change by themselves for no reason. Then there is only one answer, and that is that the physical rules of the universe have been modified by some kind of existence.

The long-distance communication based on the effect of quantum ghosts has failed. It has changed from being able to transmit effective information to being unable to transmit effective information.

Yes, humans have known this for a long time. Quantum entanglement is real. Its ghostly entanglement effect can transmit information over long distances, but it cannot transmit effective information.

This is because quantum is in a superposition state. When two quantums at a distance collapse, people cannot tell whether the other party's measurement first led to the collapse result, or whether their own measurement led to the collapse result.

To give a simple example, if two quantum quanta are respectively placed in the solar system and Proxima Centauri to determine their entanglement with each other, then when the quantum collapse of the entangled state occurs in the solar system, observers of the solar system do not know whether it is caused by the quantum collapse of Proxima Centauri or the quantum collapse of Proxima Centauri. Caused by my own measurements. Because whether it is the quantum in the solar system or the quantum in Proxima Centauri, their transition from quantum superposition state to collapse is random when viewed individually. In other words, it cannot be judged from a single perspective. It must be combined with the situation of the other party to judge. .

Based on the other party's situation, you need the other party to tell you, that is, to pass the effective information to you at the speed of light.

But in this case, the effective information transmitted based on quantum entanglement cannot exceed the speed of light.

This is a conclusion that has been confirmed by human experiments, that is, the ghostly over-distance interaction of quantum entanglement does exist, but it cannot be used for effective information transmission.

But now the rhombus crystal tells everyone here that in the past, quantum entanglement could transmit effective information over long distances and could be used as the principle of real-time communication over long distances. It is one of the basic physical laws of the universe.

The physical laws of the universe cannot change at any time, otherwise there would be no universe operating in such a precise manner. This means that the unknown existence that denies quantum long-distance communication from the level of physical laws can ensure that other rules are not affected and operate without loopholes after changing the physical rules.

All the laws of the universe have not changed, only quantum long-distance communication has changed.

Human beings cannot imagine the difficulty of modifying the physical laws of the universe, but they know that such an operation is much better than modifying the laws regardless of the consequences. Physicists have said that the universe is a precision instrument. If there is a slight change in one constant, the entire human race or even the entire universe will cease to exist.

But now there is such an unknown existence, which has changed the basic rules on which quantum ultra-distance communication relies. The entire universe and even the civilizations that use quantum entanglement for ultra-distance communication only have communication failures, instead of activating the whole body, the entire physics The system of laws has changed.

What a power this is!

Hmm. Maybe the physical laws of the universe are not as fragile as human beings imagine. They are so fragile that the whole body will collapse in one move, but this kind of direct modification of the basic physical laws will make the entire scientific and technological system established based on certain physical laws The ability to completely fail is probably only seen in novels.

But now the rhombus crystal clearly tells humans that such a thing exists in this universe, and that this technology was used three billion years ago, making the real-time communication capability of quantum gap communication in the galaxy completely ineffective from the basic law level.

"After your civilization left the galaxy, did the quantum long-distance communication system recover?" Yue Yuan asked while all the scientists were still deeply shocked.

The rhombus crystal did not hide anything, it said: "I don't know, maybe it's just the Milky Way, maybe the entire super information group, maybe the entire Great Wall of galaxies, maybe the entire universe, who knows! But one thing is certain, my civilization is That existence was not discovered from beginning to end until the final information was delivered to me.”

Yue Yuan was silent.

Even the pioneers had no way of knowing what kind of existence it was.

This kind of attack method that changes the laws of physics, even at the lowest range, covers the entire galaxy. What a powerful existence it is!

But where did such a being go?

Yue Yuan noticed that whether it is the top civilizations in the Milky Way, the Awakeners, or the Pioneers, they are all only level six civilizations, which is the interstellar level civilization category. So where have all the cosmic level civilizations gone? What was the reason for the rule change three billion years ago?

Is it a war between cosmic civilizations?

If so, how widespread is this rule change? Does it mean that the civilization embarking on the Great Voyage may reach the star field where quantum long-distance communication has not yet expired?

If there really was such a war in the universe that changed the physical rules, would there be other stars where the physical rules were modified?

Could this be what the Awakener meant when he said that space navigation is dangerous?

Thinking of this, Yue Yuan couldn't help but ask again: "So, doesn't it mean that there are similar stars in the Milky Way? Or phenomena."
