The Wandering Planet

The huge fireball engulfed the water droplets and the bow of the Ark at the same time, and the too dazzling light even turned the dome of the dungeon into white, making it impossible to see anything clearly.

Countless people are anxious to know what's going on, but they can't get any news.

Fortunately, they did not observe all this directly on the ground, otherwise it would be no different from the consequences of a nuclear explosion with the naked eye.

The flames instantly illuminated half of the earth, making the side that was originally at night as bright as day at this moment.

Luo Ji, who was on the Fang Zhou, was probably the most confused. At the moment when the water droplets rushed in front of him, he had even played back his own life in his memory, which is commonly known as the revolving lantern.

His life was divided into two distinct parts, the part after he became a Wallfacer. Although this part of his life spanned two centuries, it felt compact and dense, like a day yesterday.

He quickly reversed this part, because this part is not like his own life, including the unforgettable love, it is like a fleeting dream, and he dare not think about his lover and children anymore.

Contrary to what he expected, the life before becoming a Wallfacer is also a blank in memory, and all that can be fished out from the sea of ​​​​memory are fragments, and the further forward, the rarer the fragments.

Did you really go to elementary school? Really had a first love? Occasionally, a few clear scratches can be found in the fragmented memory. He knows that some things did happen, and the details are vivid, but the feeling has disappeared without a trace.

The past is like a handful of dry sand in your hands. You think you are holding it tightly, but in fact it has already flowed through your fingers. Memory is a river that has long since dried up, leaving only scattered gravel in its lifeless bed.

His life is like a bear breaking corn, what he gets is also discarded, and there is not much left in the end.

The raging fire outside the porthole illuminated his face. Even though the Ark had super heat insulation and anti-radiation functions, it still made Luo Ji feel as if his whole body was about to be evaporated.

In the end he fell heavily to the ground, and at the same time recovered from the revolving lantern, Luo Ji was surprised to find that nothing had happened.

The flames outside the porthole gradually faded, and the dark cosmic background reappeared in front of his eyes, but there was no trace of water droplets anymore, and he was not instantly vaporized by the ultra-high temperature propulsion halo of the water droplets as he imagined.

"What's going on? Where's the water drop?" Luo Ji blurted out.

"It has ended."

Qiao Lu's voice came from the side, making Luo Ji understand that this was not a dream.

But he still couldn't understand, how could a kinetic energy shell penetrate the strong interaction force shell of water droplets?

As if seeing through his doubts, Qiao Lv smiled slightly and said:

"It's antimatter. The explosion you see is caused by antimatter."

"You blew up water droplets with antimatter?"

Luo Ji originally wanted to say that this was impossible, but antimatter weapons were indeed extremely powerful, and a piece of antimatter the size of a rifle bullet was enough to destroy a star-class warship.

However, the strong interaction shell of water droplets is also indestructible, and no explosion, no matter how large, is enough to destroy it.

But then he reacted and corrected: "You annihilated the water droplets with antimatter?"

"Correct." Qiao Li smiled and nodded.

It is generally believed that the horror of antimatter weapons lies in their terrifying energy release,

One gram of antimatter is equivalent to the energy of a 200,000-ton equivalent nuclear bomb, that is, the power generated by the explosion of 300 grams of antimatter can exceed the 50 million-ton equivalent Tsar Bomb.

But if we only rely on the power of the explosion, the water droplets can withstand human civilization's stellar hydrogen bomb with an equivalent of at least 350 million tons without any damage, and it will not make any difference if it is replaced by an explosion caused by antimatter.

Therefore, what Qiao Li really uses is the annihilation feature of the contact between antimatter and positive matter, so as to break through the indestructible strong interaction shell of water droplets.

No matter how strong the water droplet is, it is just a regular positive matter composed of atoms and molecules. As long as it is positive matter, it will be annihilated by antimatter. Therefore, it does not matter how hard the strong interaction material is, it is just the most basic physical law.

This is the limitation of water droplets, no matter how hard matter is, it cannot avoid being annihilated by antimatter.

As a result, the water droplets were completely wiped out, and the Ark survived the explosion unscathed.

Luo Ji further asked, "That's not right. According to the data measured by the Mantis, the water drop weighs at least a dozen tons. How can you get so much antimatter to annihilate it?"

One gram of antimatter will annihilate with one gram of positive matter, so if you want to completely annihilate a water droplet, you have to take out the same weight of antimatter.

Nowadays, human civilization cannot even produce one kilogram of antimatter. How can tons of antimatter be able to annihilate water droplets.

What's more, if there is such a large amount of antimatter, even if the power of the explosion is not limited to this level, it will definitely affect the entire earth, and it is impossible for the Ark to withstand it.

Qiao Li shook his head and said, "Not so much, we only use one gram of antimatter."

"one gram!?"

Luo Ji was greatly surprised. If it was just a gram of antimatter, then human civilization really couldn't produce it.

Antimatter is not something that only exists in theory. As early as 1995, scientists at CERN produced the world's first batch of antimatter-antihydrogen atoms in the laboratory. In 1996, the Fermi National Accelerator in the United States The laboratory successfully produced 7 antihydrogen atoms.

In the 23rd century, human civilization has been able to produce a few grams of antimatter, but considering that its power is far inferior to that of a stellar hydrogen bomb, it has not been used as an actual combat weapon.

However, Qiao Li successfully destroyed the water droplet with one gram of antimatter. Doesn't this mean that the answer is always in front of him?

"How on earth did you do it?"

"It's very simple, because the shell of the strong interaction force of the water droplet is only one layer of atomic thickness."

The reason why we can realize this is because the wandering earth has also developed a strong interaction force material, as long as we compare it with water droplets, we will know why.

The shell of the earth cannon is not much larger than a water droplet in volume, but it has the weight of a whole planetary engine. The molecules of the strong interaction force material are so tight that even the atomic nuclei are squeezed together. Of course, the density is many times higher than that of natural substances. .

But the quality of the water droplet is normal, at least not to an outrageous level, which means that the strong interaction force material only exists in its outer layer, and there are other mechanical parts inside the water droplet.

In the end, according to Ding Yi's calculations, if we want to use strong interaction materials to cover the entire surface of water droplets and maintain the mass within the normal range, we can only maintain the thickness of one layer of atoms.

Anyway, in the face of a conventional weapon attack, there is no difference between a layer of atomic-thick strong-interaction material and a one-meter-thick strong-interaction material, both of which cannot penetrate.

If the content of strong interaction materials is further increased, the weight of water droplets will inevitably be doubled several times, but the steering ability will be affected due to excessive inertia.

The thickness of one layer of atoms is the design that best combines mobility and defense, and the Trisolaran civilization has also achieved the ultimate in this aspect.

But this leaves a fatal weakness for water droplets, as long as a weapon that can break through strong interaction materials, even a gram of antimatter is enough to disintegrate the outer shell of water droplets.

The strong interaction force shell of the water droplet is maintained by a special internal force field generator. When the shell is broken down, the energy released by the annihilation of antimatter pours into the interior, and after destroying the internal generator of the water droplet, the positively charged atomic nuclei quickly disperse , the atoms resume their normal movement and become a metal-like alloy with the same weight as the original water droplet, then it is no different from ordinary substances.

This is the truth of the destruction of the water droplets. The Ark fired an antimatter armor-piercing projectile rather than an antimatter projectile!

By filling one gram of antimatter inside the shell, the moment it hits the water droplet, the antimatter successfully touches the water droplet, annihilates and disintegrates the indestructible strong interaction force shell, and the rest is handed over to this nuclear bomb with an equivalent of 200,000 tons The energy of the explosion is on it!
