Chapter 502

That's right, the world of One Piece also has air, and the density of the air is not low. After all, at the same altitude of [-] meters, the air density on the blue star can't make people survive, but it can in the world of One Piece.

So Bailixiu's kinetic energy bomb is the same in the world of One Piece, flying in the air will be subject to air friction.

This is like the world before Bailixiu crossed over, rockets and planes flying in the air will be subjected to air friction, which will heat up sharply.

Of course, the speed of the kinetic energy bullet fired by Bailixiu is more like a meteorite, because the speed is too fast, so it rubs and burns in the air.

You must know that the blue star where Bailixiu was before the crossing had an average of 2 tons of extraterrestrial meteorites entering the atmosphere every year, about [-] pieces.Since most meteorites fall in inaccessible areas such as oceans, wild grasses, forests and mountains, there are very few casualties!Moreover, most meteorites will be "burned" when passing through the earth's atmosphere, so fireballs rarely appear.

However, how big a meteorite can fall through the atmosphere on a blue star?This problem is actually not simple!
The composition of extraterrestrial meteorites

In general, according to the composition of extraterrestrial meteorites, they can be simply divided into three categories:

Comet meteorites, rock meteorites, metallic meteorites.

Different types of meteorites pass through the blue star's atmosphere differently.

Comet meteorites: This type of meteorite has basically the same composition as a comet, and even itself is a fragment of a comet!We know that comets are mainly composed of ice crystals and dust, so this type of meteorite is easily destroyed by the earth's atmosphere when it passes through the blue star's atmosphere, and even the wreckage cannot exist!
So far, Blue Star scientists have only discovered the remains of a comet-like meteorite, which shows how difficult it is for this type of meteorite to pass through the atmosphere.

Rock meteorites: According to the investigation of scientists, there are many giant craters with a diameter of more than [-] kilometers on the blue star. Most of the initiators of these craters are rock meteorites!For smaller rocky meteorites, the atmosphere destroys or burns them to a very small size, making them less harmful to Earth.

But for some giant rock meteorites, the effect of the atmosphere is very small. If these meteorites fall on the earth, it will undoubtedly be a disaster for life on earth!The extinction of the dinosaurs is likely to be caused by an asteroid hitting the earth!In the face of such a huge celestial body, the atmosphere is powerless!
Metal meteorites: In fact, metal meteorites are similar to rock meteorites, except that meteorites contain more metal elements.

However, compared with rocky meteorites, this metal meteorite has a higher temperature resistance and friction resistance coefficient than rocky meteorites because of the metal inside.

Therefore, under the same volume and speed, metal meteorites can naturally fly farther in the atmosphere, and have a better chance of smashing into the ground instead of burning up directly in the atmosphere.

And the kinetic energy bullet of the star-piercing electromagnetic gun is made of tungsten metal, so the tungsten metal that is both high temperature resistant and wear-resistant is naturally better able to withstand the friction of the air, but even so, it can only barely keep it below [-] meters. The speed is not burned and melted by air friction. If the speed continues to increase, the temperature of its friction with air cannot be resisted by tungsten metal.

Of course, if you want to resist the friction and combustion of the atmosphere, in addition to using metals with higher melting points and more wear-resistant, you need to increase the volume to resist the friction of the atmosphere.

After all, the friction between the air and the meteorite is on its surface, and its surface is consumed first. Therefore, if the volume is enough, nature can increase its flight distance in the atmosphere by continuously consuming the outside of the meteorite.

Generally speaking, the speed of meteorites entering the earth is about 5000 meters per second, and the angle is about 45 degrees!Of course, there are also some meteorites whose speed is faster and can reach [-] to [-] kilometers or even [-] to [-] kilometers per second. They only exist in the troposphere for a few seconds, but it is precisely these few seconds. But it determines the "life and death" of the meteorite!
So how big a meteorite can fall through the atmosphere on a blue star is actually hard to determine!Generally speaking, small meteorites will be burned up in the process of passing through the troposphere!A slightly larger meteorite will also consume at least 90.00% of its mass to pass through the atmosphere.

We can make an analogy. When an artificial satellite passes through the atmosphere of a blue star, it will leave some debris, but there are also cases where it is completely destroyed. Therefore, using the ratio of an artificial satellite as a reference, a meteorite with a diameter of about two meters will be a critical point .

Almost meteorites with a diameter of less than two meters will be destroyed by the atmosphere, while meteorites with a diameter of more than two meters are likely to "survive"!Although tens of thousands of meteorites pass through the atmosphere on the blue star every day, very few of them can pass through the atmosphere. It can be seen that almost all meteorites are destroyed by the atmosphere!
But for meteorites with a diameter of more than ten meters or even hundreds of meters, the atmosphere cannot prevent them from falling, and if a meteorite of this size falls into a densely populated area, it will undoubtedly cause huge casualties.

However, the meteorite can ensure that it will not be destroyed by air friction by increasing its size, but Bailixiu's star-piercing electromagnetic gun cannot do this.

Because the electromagnetic acceleration orbit of Bailixiu's star-piercing electromagnetic gun can't be enlarged or reduced, the size of the electromagnetic artillery shell can only be fixed at this size.

But for this, Bailixiu has a solution, which is to use the unique armed color domineering winding in the world of One Piece.

As long as the armed color domineering is wrapped around the kinetic energy bullet, then there is no need to worry about the kinetic energy bullet rubbing against the air.

It is conceivable that if Bailixiu really solves the problem of friction and combustion of kinetic energy bombs, it will be possible to snipe and kill the opponent outside of the range of knowledge and domineering.

For example, if the opponent's knowledgeable domineering range is one kilometer, then Bailixiu will snipe and kill within one kilometer. Even if the enemy's knowledgeable domineering senses the attack and kill of the kinetic energy bullet, he will still be killed because he has no time. kill.

After all, it only takes one tenth of a second for a 1000-meter-per-second electromagnetic kinetic energy projectile to fly over a distance of [-] meters.

In such a short period of time, even those who can knock down a mountain with one punch probably don't have time to dodge.

Moreover, the armed domineering winding electromagnetic kinetic energy bullet can not only isolate the friction with the air, but also further enhance the hardness of the electromagnetic kinetic energy bullet and increase its ability to penetrate armor.

However, the idea is beautiful, but the reality is very cruel, because now Bailixiu simply doesn't have enough time to learn Armed Color Domineering, let alone the further application skills of Armed Color Domineering.
