Voyage of the Stars.

Chapter 1236 Quantum Entanglement Long-Distance Communication
However, with such a short distance, many level six civilizations have already failed. They are either civilizations in the Great Voyage Organization or civilizations on the voyage route of the Great Voyage Organization.

Every inch of the starry sky and every bright star in the night sky are telling their own stories. Some events have been experienced by human civilization, while others are forever outside the event light cone of human civilization.

If a civilization born in the M87 nebula also looked up at the stars like humans did on Earth, and looked in the direction of the Milky Way, and if they had the ability to see the Earth, then the Earth they see now should be just recovering from the asteroid impact that caused the extinction of the dinosaurs, and the ecological environment of the Earth is gradually recovering, and the ancestors of mammals are rising.

Faster than light is so amazing.

If there really is such a civilization with extremely strong observation capabilities, I wonder how they would feel when they learn that the group of mammals they see now have actually come to their homes in warships in a highly civilized manner.

Perhaps they will point to the small mammals on Earth that have just crawled out of their holes and say to humans: Is that you? Why don't you look like them?

And humans might respond like this: I'm standing right in front of you, and you can see how I look like I used to.

Unfortunately, due to the limitations of observation levels, such things will not occur in the universe, or in other words, they will not occur at the level of sixth-level civilization.

Therefore, when updating the observation data of the M87 nebula, scientists of human civilization can only exclaim, "So this is what it is like," "It has undergone such changes in million years," and "Is this its true appearance now?"

Scientists who think more deeply may ask, "Does time really exist?" and then think about things like the event cone and the nature of time.

The observations in the Earth era are all of its appearance 87 million years ago, and it certainly looks different now. In the human database at that time, the central black hole of the M nebula is a supermassive black hole with a relativistic jet, whose jet material is close to the speed of light and the length of the jet reaches light years.

Such a huge relativistic jet can still be captured by human radio and X-ray telescopes even if it is 54 million light years away.

It still has relativistic jets, but their intensity has been significantly weakened because the black hole can swallow less matter.

Such changes will also provide valuable data for human civilization in studying the relationship between supermassive black holes and galaxy evolution. Humanity's high-energy physics field will also make progress due to the updated data.

In fact, it is not only humans who benefit, because M87 has a relatively special position in astronomical history. Civilizations born in the direction of the line between it and the Milky Way can generally observe its previous appearance and record it.

The reason why humans pay so much attention to this area is not only because of M87 itself, but also because other member galaxies in the Virgo Cluster are also quite special. For example, its other member galaxy, M100, is a key calibration point for humans to measure the scale of the universe through Cepheid variables, and is also an important measurement object for the expansion rate of the universe, namely the Hubble constant.

It can be said that this star field has important significance in the history of human astronomy development. The first black hole photo taken by humans was the central black hole of M87.

It is precisely because of this that many old people from human civilization who come here have a sense of déjà vu, a feeling similar to when they walked out of the solar system and reached Betelgeux: we have come to the place recorded by the ancient philosophers while looking up at the stars.

Whether it is the Pleiades or the M87 nebula, behind each name there is a story of ancient philosophers looking up at the stars. Perhaps when they first looked up at the stars with curiosity, it was destined that future humans would turn curiosity into a sail for a long voyage, and visit those places that they could only see from afar.

From Chang'e flying to the moon to Kuafu chasing the sun, from Kongming Star in the constellation of Betelgeux to M87 today, that is the romance of the universe, and also the victory of that curiosity hidden in the depths of wisdom.

It is the curiosity deep in my wisdom that has set sail for knowledge. "This galaxy is so huge!"

On the Tianqin, an astronomer looked at the updated data and exclaimed to his colleagues.

Data shows that the supermassive black hole at the center of M87 has a mass of 65 billion times that of the sun, while the central black hole of the Milky Way has a mass of only 440 million times that of the sun, and the central black hole of the Andromeda Galaxy has a mass of only 1 million times that of the sun.

However, its diameter is not much larger than that of the Andromeda Galaxy, which is only about 300,000 light years. But it has several times more stars than the Andromeda Galaxy, which is not contradictory, because the universe is three-dimensional, and the diameter is a parameter that extends in all three spatial dimensions.

While astronomers from various civilizations were marveling at the size of M87, a piece of news from quantum physics came like a thunderclap, sweeping across all civilizations of the Grand Voyage Organization. Oh no, even the sixth-level civilizations in the Falcon Voyage Organization were shocked.

The source of the news is the Yinxin civilization.

As a civilization that has only recently mastered its own unique technology, they are very proud of their unique technology in detection and communication, and often say in public virtual meetings that they are the eyes of the Great Voyage Organization.

Such pride has also made them form a habit after their repeated voyages across the galaxy, which is to explore the starry sky before other civilizations, such as drawing new star maps, correcting old star maps, and of course the testing of communication systems that they have been doing.

This time the news came from the communication system.

When the scientists of the Galactic Center civilization conducted the first experiment, they thought they had made a mistake. It was not until they repeated it dozens of times and found that the result was correct that they dared to report the conclusion to their leader.

Scientists from the Silver Heart Civilization were shocked to discover that quantum entanglement long-distance communication had actually been realized here. And this news spread to all civilizations at the speed of tachyons in an instant. As a result, the civilizations of the two major voyage organizations immediately set out to verify the experimental results of the Silver Heart Civilization.

Without any surprises, all experiments yielded the same result: quantum entanglement can transmit effective information at speeds exceeding the speed of light.

Since the Great Voyage Organization had already learned about quantum entanglement and long-distance communication from the pioneers, after discovering that quantum entanglement and long-distance communication here was actually effective, the various civilizations immediately came to two conclusions.

First, the real-time communication of quantum entanglement has never failed here. Second, it failed before, but it recovered.

From behind this incident, each civilization also got a glimpse of the impact of the legendary cosmic civilization war. The cosmic civilization is so powerful that they can actually change the laws of cosmic physics on an astronomical scale of tens of millions of light years.

People who woke up from their trance couldn't help but feel fortunate that what was changed was the superluminal effective information carrying law of quantum entanglement, which had little impact on the warships and life survival of various civilizations. Otherwise, everyone would have been finished by now.

At this moment, the image of the Paper Civilization unconsciously emerged in the minds of many people, and they recalled the warning or the reason why the Paper Civilization went to the Sculptor's Hollow.

It seems that the route towards the Bootes Void is indeed difficult to travel!
