After introducing the manufacturing principle of strong interaction force materials, Ding Yi suddenly turned his head and said:

"By the way, Qiao Lu, guess how much this thing weighs?"

This really stumped Qiao Lu, and if you think about it carefully, you know that the nucleus of an atom is equivalent to the ratio of the size of an ant to the size of a stadium, and the density of matter compressed to this extent must be beyond imagination.

"I'm afraid there will be tens of thousands of tons?" Qiao Lu asked hesitantly, he was really not sure about this number.

Shen Huabei on the side shook his head and said, "Far more than that!" Let's just say it's as heavy as a planetary engine! ”

Qiao Lu couldn't help but gasp, the metal sphere in front of him was just the size of a flint equivalent to a planetary engine, and it actually contained the weight of an entire planetary engine?

"You mean, the Earth Cannon is firing a planetary engine!?"

Ding Yi replied: "Let's just say that, if you want to talk about the cost, the resources consumed may be even more. ”

So far, The Wandering Earth has unlocked a variety of uses for planetary engines, but compressing planetary engines into cannonballs is a bit of a test of imagination.

"You're mad!" Qiao Lu sighed.

Launching an entire planetary engine as a cannonball, such kinetic energy is simply unimaginable, and it is true that only the Earth Cannon can do such an exaggerated thing.

Not to mention anything else, throwing this metal sphere at the earth now is estimated to be enough to destroy the entire earth, and there is no need to launch it at all.

"It's going to pass through the earth like a bullet through cheese?" ”

"Ahem, I guess it's even scarier than that." Ding Yi replied:

"As I said earlier, its surface remains at absolute zero because the vibrations of the molecules are completely gone. But it also means that if the energy generated by the outside world is large enough, it is still possible to make its molecules vibrate again. ”

"So when it hits a planet at high speed, the huge kinetic energy generated by the impact, the high temperature and high pressure when it passes through the center of the earth, will cause the molecules on its surface to vibrate again, and then produce a chain reaction that spreads throughout the sphere—"

When he heard the chain reaction, Qiao Lu understood what was going to happen.

When the nucleus of an atom breaks off the strong interaction force and splits into multiple nuclei, the result is nuclear fission accompanied by a huge release of energy.

In the same principle, when this strong interaction force material is fissioned due to the huge kinetic energy of the impact and the high temperature and high pressure of the earth's core, the resulting explosion is equivalent to the power of hundreds of millions of tons of nuclear bomb explosion, which should be converted into trillions of tons of TNT equivalent, there is no need to calculate, anyway, no planet can withstand it.

This is a complete star-destroying weapon, and even the other way around, if it is not a large enough planet, it will not even be able to detonate it!

For example, a planet the size of the moon passed through like a bullet through cheese, leaving only traces like minimally invasive surgery.

But when it hits the Earth or even a larger planet, the consequences are as unimaginable as just mentioned.

In addition, it should be noted that although it is a strong interaction material like the water droplets in the three-body problem, the difference is still quite large.

Only the outer shell of the water droplet is a strong interaction force material, which wraps around the artificial intelligence computer, the strong interaction force generator, the thruster for compressing the electronic rain, and 12 space force field engines for sharp angle turns, etc.

So the mass of the water droplet is only about the weight of a truck, not the weight of a planetary engine like the metal sphere in front of you.

What's more, the shell of the water droplet is pinned by the force field generated by the strong interaction force generator, and is not manufactured by compression.

The typical feature is that the electrons outside the nucleus are not pressed into the nucleus and neutralized with the positively charged protons as neutrons, but form a flowing electron rain on the surface.

The electron rain quickly converges towards the tail of the water droplet in the form of pulses along the absolutely smooth surface of the strong interaction force material, forming a beautiful electron vortex ring, which is also the force that pushes the water droplets forward.

All of these factors result in the fact that the water droplets do not explode violently like a chain reaction, and because the strong interaction force field always locks in the vibrations of the molecules, there is no re-vibration of the molecules.

Once the internal strong interaction force field dissipates, the strong interaction force material in its outer layer will fall apart due to the electromagnetic force repulsion between the protons, and no energy will be released.

Depending on the manufacturing method, the properties of materials with strong interaction forces are also very different.

The Wandering Earth does not produce water droplets, but another material with strong interaction force, which is close to neutron degeneracy in physical properties, and releases huge amounts of energy when it changes back to normal matter.

In any case, this weapon is powerful enough to destroy a planet, but it is quite expensive, after all, it is the weight of a planetary engine that is being launched.

"In that case, how are we going to use it against the Death Star?"

Qiao Lu finally remembered this most critical problem, the diameter of the Death Star was only 160 kilometers, and it was definitely not enough to detonate this cannonball.

"If it's just to destroy the Death Star, it's really not worth the trouble we have to go to such length." Ding Yi replied, "But in order to obtain the energy core of the Death Star, you have to do this. ”

"What do you mean by that?"

"The Death Star isn't big enough to detonate this cannonball, so we can use it to deliver a surgical, pinpoint strike that pierces the Death Star's command room in one hit. Without damaging the power core, paralyze the Death Star completely. ”

Shen Huabei answered: "But according to the information provided by Galen Ersor and the Death Star blueprint, the command room of the Death Star is located above the top edge of the super laser cannon launch. If we want to hit the command room with precision, and also avoid damaging the Death Star's energy core as much as possible, we can only perfectly achieve our purpose by using the Earth Cannon to return fire at the moment when the Death Star actively aims its super laser cannon at us. ”

Qiao Lu frowned and said, "But if we let the Death Star's super laser cannon hit the earth, won't we lose all our efforts?" There is no point in dying together! ”

The Wandering Earth is not crossed over to overthrow the rule of the Galactic Empire, and there is no point in exchanging the Death Star at the expense of the Wandering Earth.

If you can use the earth cannon to destroy the command room of the Death Star while avoiding being destroyed by the super laser cannon, this will be the real happy ending.

Ding Yi nodded and said, "That's right, we also took this into account, so-"

"We're going to use Earth Cannon to fight the Death Star!"
