The particle of light is the ultimate weapon of the three empires capable of intimidating the entire galaxy.

It's not some kind of single particle, it's an extremely complex storage structure, to be precise.

A large, barrel-shaped starship slowly emerges from the darkness. The front and middle parts of the ship are hollow pipes like gun chambers, and the tail end is a giant spherical reactor.

At the bottom of the spherical reactor, a high-energy laser cannon was installed, and as the countdown of the ship's spiritual electronic sound came to the end, the high-energy laser cannon opened fire violently.

The laser, which cannot be seen directly by the naked eye, suddenly blooms in the vessel, trying to break through the blockade of the reactor with the blazing heat.

The inner wall of the reactor is covered with a layer of scale-like crystal-like "mirrors", these mirrors have extremely high light reflectivity, and in the time of 1us, the light is set 3000 times, and because the light absorption of the crystal itself is extremely weak, the light intensity has not been reduced much.

The light is then projected into a gourd-shaped cavity at the top of the reactor by mirrors. This cavity has two parts, the lower part of which is a thick photonic crystal cavity that stores light for a few nanoseconds.

These few nanoseconds are enough to get the starship running, the engine at the tail of the hull provides energy, and the long conduit in the center is filled with electromagnetic fields.

After a few nanoseconds, the light detaches from the photonic crystal cavity and enters the upper part of the gourd-shaped cavity.

It's full of waves—cold atoms condensed by Einstein, and the speed of light is reduced to a very slow speed visible to the naked eye, even gradually approaching zero, using EIT electromagnetic induction transparency.

As a result, a beam of stationary photons is stored in the cavity.

In the eyes of the vast majority of civilizations that have developed classical electromagnetic theory, the photon itself has no rest mass, and if it does, then quantum electromechanics will be completely destroyed, and the theory of conservation of charge will be completely destroyed.

But, that's just for ordinary civilizations.

Humans cannot directly prove that the mass of photons is 0 by experiments, but can only calculate the upper limit of the geostationary mass of photons by measuring the planet's magnetic field by satellites - the vast majority of experiments have proved that the upper limit of the mass of photons is extremely low and very low, far from being compared with the lightest particle neutrino.

And the top civilizations such as the three empires can give a clear answer: the mass of the photon can be 10 minus 48 kilograms, which is one thousandth of the mass of an electron.

The mass of a photon is equal to one thousandth of the mass of an electron.

This may seem like a small weight, and even if an entire chamber were filled with the same photons, it would be nowhere near as heavy as a single hair.

However, whether it was the Empress, the Warlord, or the Supreme Wisdom, they all stared at the images on their respective flagship screens with the most solemn eyes.

The cavity, which carries photons of the weight of a hair, is packed into the rails with the utmost care.

Unfortunately, no sound can be heard in the vacuum, and when the ray burst at the end of the rail hits the cavity, enveloping the photons and pushing them towards the sun, the whole process is silent, and people cannot directly appreciate the solemnity and grandeur of it.

At this time, the overall construction of the Black Domain was mostly completed, and the photons with slight mass had just passed through the only exposed hole in the Black Domain.

The light particles passed through the black field, slowly crossing a distance of several light minutes at the speed of light, and because of the Doppler effect, they dragged a long redshift trajectory on the regular monitoring screens of the three empires.

Once the photon with mass hits the star, it will blast through the corona, chromosphere, photosphere, and troposphere, carving out huge holes, causing the star to crack and collapse under the sudden unbalanced gravity.

The three empires rarely use light particles, and each time they do, the light particles will directly destroy all living things in an entire star system - the intense radiation released by the stars will directly scorch all the planets within a certain distance, and the subsequent star explosion will also destroy the planetary bodies that are far away.

The leaders of the three empires stared at the picture extremely nervously,

The black domain is the "shield", and the light particles are the "spear", if the other party wants to solve the light particle threat, they must first destroy the black domain. But even if he had the Cosmic Cube and could erase the slowdown effect of the Black Domain, the whole process would take time - just enough time for particles of light to hit the sun and scorch the galaxy.

This is a completely contradictory thing, for thousands of years, the three empires have used the routine of light particle strikes and black domain blockades to wipe out one after another hostile civilizations that may rise, and if it goes well, the earth should also be a footnote to the victory of the three empires.

Why? Why hasn't that transcendent one appeared yet?

In the surveillance footage, the light particles are getting closer and closer to the star, but their sense of foreboding is getting stronger. This tingling sensation gradually spread to themselves, entangled their hearts like vines.

The Black Domain is far from being fully constructed, and only one last area needs to be filled.

.....

"Here they are."

In the accelerated world, Magneto stared at the calm and unwavering sky and said softly.

"Them?" Professor Charles hurriedly turned to the Central Intelligence Brain and saw the three imperial ships break away from the void and unfold the black domain of the solar system.

"Shhhh

Professor Charles gasped, the other party came too quickly, far more than he expected.

And the Central Intelligence Brain also gave the information of the black domain in a very timely manner.

"Once the Black Domain is fully constructed, the speed of light in the solar system will be limited to the speed of the third universe, which means that it will be difficult for conventional objects to leave the solar system."

Leon spoke calmly and calmly.

Professor Charles pursed his lips and said bitterly: "But you have a cosmic Rubik's Cube, and it stands to reason that you should be able to tear this spatial fold..."

"I do," Leon nodded, "but they're the smartest, or at least the most powerful, alien creatures in the galaxy, and they're far less stupid. What we can think of, they can think of too.

The complete Black Domain appears to be just creating spatial folds and reducing the speed of light, but in essence it is a prison of time.

When the speed of light decreases, although the life forms in the Black Domain will not detect any abnormalities, from the perspective of the life forms outside the Black Domain, the speed of time in the Black Domain will also be slowed down to the limit.

This concept is roughly similar to our brain world in a tank, except that the proportion of the flow rate of time concepts inside and outside the black domain is more exaggerated, and to the outside world, everything in the black domain is almost stagnant.

As long as they fill the last area, we will be completely trapped in it, and even if I can use the Cosmic Cube to get out of it, it will be hundreds of millions of years away for the outside world.

At that time, the three empires that had been washed by the torrent of time probably didn't even have scum left. ”

Professor Charles, who is also an old man, frowned and asked hesitantly, "Then why .....?"

"Why didn't they just close the Black Domain completely, and leave us a crack in the door, right?"

Leon smiled and expressed Professor Charles's confusion, and said calmly: "Because their mission is to completely wipe out the earth civilization, not to lock the earth civilization in a black box that can never be touched, which is obviously different from the order they received.

Second, they are also afraid. If the door of the Black Domain is completely closed, then everything inside the door is unknown. I have the Cosmic Rubik's Cube, and I can break down the door at any time, so the three empires that bear the heavy responsibility must stay outside the door and wait.

Thirdly, the question is, even they don't know when I'm going to break out, a thousand years? 10,000 years? Or 100 million years? They will wait outside the door until they die!

Fourth, the brain world in the jar is still running, and the humans in the black domain have endless time to climb the peak of science and technology, and when the black domain is broken, what if the humans in the gate have developed zenith star technology?

These aliens can't afford to gamble and don't dare to bet! That's why they set aside a crack in the door, and they had to wait for me to appear in the camera to confirm my next move before they could react to my rhythm.

In other words, they were inviting me in. ”
