Chapter 849: A Punch Comparable to a Nuclear Bomb

"When the Angelis meteorite hit the planet, how much energy was generated?" Eve was suddenly curious about the topic of the meteorite hitting the planet.

"This question..."

Da Liu pushed his glasses and analyzed: "This issue needs to be discussed separately. When a meteorite hits a planet, the first is kinetic energy, and then it may explode when it hits the ground.

"If you want to calculate the energy of the explosion, it will be more troublesome, but the kinetic energy is relatively easy to calculate.

"And, in fact, in terms of destructive power, the destructive power of one-way kinetic energy is far higher than that of an explosion."

Someone asked in doubt: "The power of the explosion is smaller than the kinetic energy? Isn't it?"

After thinking for a while, Da Liu explained: "Actually, in the impression of many people, there will be an illusion, subconsciously thinking that the explosion is very scary.

"But in fact, the destructive power of the explosion is very average compared to the unidirectional kinetic energy.

"It's easy to understand with an example, just take a bullet.

"The destructive power of the bullet after it is discharged from the chamber all comes from the gunpowder in the shell.

"So, if we pour out the gunpowder in the eggshell and make a firecracker, what do you think the power will be?"

This example is indeed very easy to understand. If the gunpowder in the shell is made into a firecracker, it will explode directly in the hand, and the power will not be too great.

Da Liu went on to say: "This is easy to understand, right? Using the gunpowder of a bullet as a firecracker, the most destructive power is the skin-breaking level.

"However, such a point of gunpowder, placed in a bullet, converts energy into kinetic energy when it explodes, and when the bullet is shot out, it can penetrate the hardest skull.

"From this it can be seen that kinetic energy is more destructive than explosion.

"In fact, most of the destructive power of the explosion is reflected in the shock wave. In fact, it is still kinetic energy destructive power. It is just a spreading shock wave. The farther the range is, the less damage it will cause."

Comparing the destructive power of firecrackers and bullets, it is indeed possible to clearly distinguish the difference between the destructive power of kinetic energy and explosion.

Eve tapped her chin with her finger, and said thoughtfully: "So, kinetic energy is indeed more destructive. No wonder an asteroid with a diameter of ten kilometers hit the earth and wiped out all the dinosaurs."

Da Liu typed out a set of data on his notebook,

Then he did some calculations and said: "As for the energy of the Angris meteorite hitting the beast planet...

"Let's calculate the kinetic energy of this meteorite's impact.

"Based on the exploration and analysis of the crater, we can probably draw a conclusion that the diameter of the Angelis meteorite is about three to five kilometers...

"Combined with the density of the magnetite and a portion of the rock, we can calculate an approximate mass.

"For the convenience of calculation, we take an integer, the mass of the Angelis meteorite, 30 billion tons.

"Then there's the speed at which the meteorite fell.

"The falling speed of meteorites on the earth is about 20 kilometers per second to 70 kilometers per second.

"Judging from the degree of fragmentation of the meteorite fragments in the Angelis crater, we can speculate that the impact velocity of this meteorite should be low.

"Therefore, we assume that the impact speed of the Angelis meteorite is 20 kilometers per second, and then calculate the kinetic energy at the time of impact.

"The final answer is 6 x 10^21 joules.

"6 times 10 to the 21st power, which is 60 trillion billion joules, converted to a higher unit, 600,000 kilojoules."

Hearing this number, Fang Yuan couldn't help but take a deep breath.

600,000 kilojoules, which is a terrifying order of magnitude.

Eve couldn't help but began to point her fingers: "The captain's dark matter dragon fist can hit 115 trillion joules, so..."

She wanted to calculate the difference, but found that the value was too large, so she couldn't calculate it all at once.

Fang Yuan coughed quickly, and said: "Then what, let's calculate the power of the little boy."

The numbers are so different that it's hard to compare.

After all, an asteroid with a diameter of five kilometers has a mass of 30 billion tons, and the quality of light is not comparable to that of humans.

However, if it is the nuclear bomb called "Little Boy", it is somewhat comparable.

In the last century, the nuclear bomb named "Little Boy" was dropped on an island and almost ended a war.

Chen Likun was particularly interested in this kind of data analysis, and quickly took up the conversation: "I remember the data of this nuclear bomb very clearly.

"The little boy is 15,000 equivalents, converted into joules, that is 63×10^12 joules, which is 63 trillion."

Hearing this value, Fang Yuan was a little satisfied, with a smile on his face.

Eve began to count with her fingers again: "The little boy with 63 trillion joules, the power of the captain's dark matter dragon fist is 115 trillion joules...

"Hey, it's almost the same. Captain, you can do it. You can hit two nuclear bombs with one punch."

From the numerical point of view, the power of Fang Yuan's punch is indeed equivalent to twice the energy produced by the explosion of "little boy".

However, the problem of kinetic destructive power and explosive destructive power still exists.

The Dark Matter Dragon Fist is a unidirectional kinetic power, while the nuclear bomb explosion is a spreading power in all directions.

The difference between the two can indeed be compared with firecrackers and bullets.

Therefore, in terms of destructive power alone, the destructive power of the 115 trillion joules of dark matter Dragon Fist at one point far exceeds that of the "little boy".

However, the destructive coverage of the Dark Matter Dragon Fist is relatively small.

Therefore, if it is used to deal with the tide of star beasts, nuclear bombs like "little boy" are actually more effective, and the dark matter dragon fist is more suitable for killing high-level star beasts.

Fang Yuan said with a serious expression: "It's not enough to hit twice the power of a nuclear bomb with one punch. I said what does the staff want from me?"

The person in charge of the assessment team said blankly: "'Little Boy' was already a fission bomb in the last century, with a yield of only 15,000 tons. Now the nuclear weapons commonly used by humans are hydrogen bombs, most of which have an equivalent of more than 500,000 tons. It's not enough to compare."

Eve helped to argue: "That's not right. How can the destructive power of kinetic energy be compared with the destructive power of an explosion? The destructive power of firecrackers and bullets is ten times worse, right?"
