A few days ago, the Andes Mountains of South America.

Beyond the 1,700-meter-thick rock formation, there is a huge cavity deep underground, and under the irregular dome is a calm underground lake.

A few years ago it was just a giant underground cavern that could no longer be ordinary, but now it has been occupied by aliens, and the lake is overgrown with giant alien vines that lead to the dome, and the servants shuttle back and forth between the giant vines; The water was full of giant insects, jumping up to the surface from time to time; The irregular dome is overgrown with glowing plants, bringing a little light to the dark cavern.

In the northwest corner of the underground lake, several giant insects suddenly rushed out of the artificial tunnel that led to the unknown direction, and on the back of each giant insect sat an alien covered in carapace.

They rushed all the way to the underground lake, almost into the water before stopping.

The nearby servants hurriedly leaned over, supported their chests with one hand, and bowed down to greet the aliens.

The servants were tall and stood only a little shorter than the alien sitting on the back of the worm, but the status of the two sides was extremely unequal.

The aliens ignored the servants and jumped off the giant worms, which served as mounts meekly lying on the shore, and none of them ran around.

The servants didn't dare to approach at all, they stood there honestly, not daring to move, until the alien at the head waved their hands, and they quietly retreated.

One of the aliens looked left and right, then pointed to a giant vine near the shore: "That's it!" ”

The giant vine went straight up and down, one end rooted underwater, the other attached to the dome, and there was only an unsightly sac at a height of more than a meter above the water.

An alien waded into the water, walked to the giant vine's bag, looked inside, and then turned around and touched his forehead, which in alien habits means good, okay, mature, and so on.

The alien on the shore responded with the same action, and the man turned around and slit open the sac, releasing a worm-man with deformed legs.

The wormman fell weakly at the feet of the alien, and the alien who was high up condescended: "Get up!" ”

The four-legged insect man got up from the water slowly, trembling and not daring to look up.

An alien asked contemptuously, "Is it that he understands the laws of the stars?" ”

"That's him." The other alien replied affirmatively, "I just sent it back and put it in, and it was ripe today...... He is the most important thing we have learned in the past few years, and in human parlance, we should call him an expert in the laws of the stars, as I have confirmed from the slaves. ”

"Raise your head!" Aliens say.

The wormman looked up, his eyes full of confusion.

"Tell me the laws of the stars!" Aliens speak with a threat.

The worm people are still at a loss, and they don't understand the meaning of aliens at all.

The alien was furious, and he raised his leg to give the insect man a kick, but he didn't want to be stopped by his companion: "He may not understand what you mean." ”

"How so?" The aliens are puzzled.

Changing people from insects is a new technology that has only recently been developed, and the failure rate is terrifyingly high, but this method of changing people from vines has been used for many years, and the failure rate is negligible.

The worm man in front of him is impossible to control and fail.

"Look at me." The alien walked up to the insect man and asked in a low voice, "Do you know the laws of the stars?" ”

The wormman shook his head in confusion.

The alien looked back at the others: "I knew!" ”

"I don't know what I'm keeping him for?"

"Keep watching!" The alien turned around and looked into the wormman's eyes, "Stellar weapons, do you understand?" ”

The wormman still shook his head.

"A stellar explosion?"

The wormman still shook his head.

"Stellar fragments?"

The wormman still shook his head.

Now the aliens didn't know how to describe it, so they thought about it for a while before changing to another way: "What is the most powerful weapon of mankind?" ”

The wormman finally reacted, but opened his mouth but said nothing.

At this time, the alien couldn't bear it anymore, and asked sharply: "Do you know or don't know!" ”

"Yes!" The wormman replied very clearly, "But I don't know how to say it." ”

Although his mind is full of alien language, there is no such concept of atomic nucleus in alien language, and he wants to find a similar concept, but what kind of expression does he use?

Particle?

No!

Neutrinos?

Nor ...... It seems that aliens' understanding of matter has gone into a misunderstanding, and their understanding of the microscopic level is only at the cellular level...... To be precise, it's the cell structure, DNA or something, that is, at the molecular level, and it's a macromolecule, and there is no concept of atoms at all.

But how can cells be understood as atoms?

The insect man was stunned by all the aliens, and the most impatient one immediately asked, "What do you say?" ”

Worm Human: "Nuclear eapon, humans call it Nuclear eapon, I don't know how to say it, I can't find the right language!" ”

Speaking of this, the insect man suddenly hugged his head, and the whole person fell into panic and uneasiness.

The alien had realized that there was something wrong with the way he was asking, and immediately changed his words: "No matter what it's called, I want to know this thing, the more detailed the better!" ”

The nuclear physicist who transformed into a worm man obeyed the orders of the aliens in his heart, but he didn't know where to start for a while.

The alien knew that he had indeed caught the big fish this time, and he knew that this person must have been controlled, so he did not rush to urge it, and waited patiently for the insect man to speak.

The wormman thought about it for a while, and finally decided to start from the beginning: "First of all, it's the atomic ......"

Worm people started with the concept and structure of atoms, first gave the most basic physical concepts to this group of lo B aliens, and then talked about special relativity, time expansion, length contraction, mass-speed relationship and so on, and finally talked about the mass-energy relationship.

Hearing this, all the aliens had their eyes lit up, their full attention, and they listened carefully word for word.

In fact, aliens know what an atom is and what the nucleus is, but such a profound knowledge can only be mastered by real aliens, and it is impossible to instill such valuable knowledge into the slave soldiers, so they make this kind of oolong full of knowledge, but they can't find words to describe it.

But when it comes to the relationship between quality and energy, it is a new concept that aliens have never been exposed to, and whether the aliens present understand it or not, the only way to do it is to keep it in mind first.

It wasn't until the wormman's statement came to an end that the aliens breathed a sigh of relief, and then took out the things they didn't understand, and asked one by one, even why E equals mc2.

The worm man was almost asked by the alien to collapse, E=mc2 is E=mc2, where is there so much why?

In the end, he could only explain that the relationship between mass and energy is one of the greatest and most profound discoveries of human beings, and this thing involves very advanced mathematical knowledge, and he is engaged in physics, but he is really not good at mathematics, and the specific process is really unclear.
