"In the past week, there have been no hotter words than interstellar voyages and space folding, and even the front line in Nia is not as noticeable as these two words, and when people are very surprised, there must be a part of them who always stay sober and rational, and objectively look at the advantages and shortcomings of the current situation, that is, us. Pen, fun, pavilion www. biquge。 info”

"Before starting today's class, let's start with this interstellar voyage and space folding, and analyze, behind the optimistic mood, the hidden dangers are buried."

Wu Chen, like an ordinary college student, holding a textbook and notebook, chose a front seat to sit down in the lecture hall, and the old professor who lectured glared at him dissatisfied, so he ignored him and continued to face the circular lecture hall and talk eloquently.

"The practical application of space folding has been successful, and people seem to have entered the interstellar age all of a sudden, and the calls for going out of the solar system and entering the galaxy have come and gone, so why, for the past week, the official attitude has been calm, and no ambitious interstellar voyage plans have been announced? Only one Mars development project has gone into form? ”

"The reason is inseparable from our curriculum, and that is that we are currently facing a huge shortcoming - materials!"

"Why do you say that?"

"Students who are concerned about the practical application experiment may remember that the output power of the nuclear fusion reactor exceeded the maximum volume of the magic matrix unit, and the energy overload reaction reached 500%, under normal circumstances, this experiment has failed so far, the pure gold and mythril used to build the magic matrix will definitely be ablated, the planarized energy used for the two points must overflow, and under the chain reaction, the other mechanisms inside the spacecraft will definitely be destroyed by the huge energy......"

"Why is this happening?"

"The reason is that the purification of two special substances, Adamantite Gold and Mithril, has not been able to achieve a breakthrough for a long time!"

Wu Chen wrote down the three keywords of pure gold, mythril, and purification in his notebook, and then looked thoughtful.

"Yes, these two special substances are fundamentally different from the original matter of our earth, and the smallest unit that constitutes them is not the arrangement of molecular formulas, but the solid formation of energy combined with a special tiny molecule. Under the high-magnification microscope, these two substances are in an energetic liquid state, in this state, there are about 20-40% impurities, these impurities are difficult to refine by current technical means, in the case of the highest purity of only 80%, the magic matrix unit constructed in the integrated circuit mode, perhaps the size of a fingernail, integrates thousands of magic arrays. Just like ordinary circuits, the huge amount of energy flowing in it will cause loss per unit area, and under the loss and conversion of energy, it can cause a huge local high temperature, which may cause the burning and short circuit of each unit circuit......"

"Why am I emphasizing this? The reason is that in the process of space folding, the farther apart the two points of AB, the more huge energy is required to act in the magic matrix unit, and the three-dimensional space based on the two points of AB is flattened at the energy level, and the farther the distance, the higher the energy and the greater the power...... Lo and behold, everyone understands that with the existing purity of Adamantite and Mithril, it is dangerous to fold space beyond the safe power, and this practical application has been successful, what about next time, next time? It must be known that the distance of this space folding is only 450,000 kilometers, which seems extremely far, but it is only the extent that light can reach it in 1.5 seconds, and this is already the limit we can achieve with space folding technology! ”

"Anyone with a little common sense knows that the maximum folding distance of 450,000 kilometers is far from enough to support human beings to enter the galaxy, and even a thousand times or ten thousand times will not help, the minimum speed scale for interstellar navigation should be positioned as light years, and what about us now, it can only be 1.5 light seconds!"

Wu Chen was already frowning when he heard this, he rubbed his temples with a headache, and he felt very tricky for a while!

His Majesty's power doesn't seem to be able to solve this problem, he can come up with 100% pure Adamantite Gold and Mithril, but he can't make all Adamantite Gold and Mithril easily purified by the existing technology from the level of law.

His Majesty's power is not unlimited, especially when his main realm and power are still limited to Nia.

"This is the huge shortcoming we are currently facing in the field of materials, and is this shortcoming only reflected in the folding of space?"

"No, it's not!"

"As we all know, those so-called starships are still using backward rocket boosts to get out of gravity, are there no more advanced power engines? No, it's not, there are controlled fusion reactors that can provide far more power than a rocket engine, but the alloy used to build the spacecraft can't withstand such a huge energy output, even at the lowest power! ”

"Professor!" A student raised his hand, and after receiving permission, stood up and questioned, "Two days ago, the latest space shuttle that the International Space Agency has announced, its power plant seems to have abandoned the rocket engine, and directly uses the nuclear fusion reactor as a reusable power, and it can also directly locate the moon from the earth's base, and it can use the space folding engine to teleport from the earth to the moon without even taking off!" ”

The old professor smiled and motioned for the students to sit down while explaining, "Space shuttle? I don't know if you have noticed, the size and volume of this space shuttle? Yes, with the reduction of volume, increased mass and density per unit area, this space shuttle can offset the huge stress overload of the nuclear fusion reactor to the greatest extent, but this space shuttle, which is only the size of a space shuttle, may be used as a space fighter or something, can it act as a huge transport aircraft and cargo spacecraft? ”

"No, if the shortcomings of the material are not solved one day, it will not appear one day."

"There are many, many examples like this, now, our background in the occult is still too shallow, far from the time when you can sit back and relax, students, don't be too ambitious, there are still countless difficulties in front of you in the future, okay, now we have normal classes, please turn to the one hundred and fifth page of the textbook, today we are going to talk about the correspondence between magic materials and molecular formulas."

The buzzing discussion stopped, and one of the students seemed unwilling, and finally couldn't help asking, "Professor, can it be that the current interstellar voyage can only be a mirror?" ”

The old professor took off his glasses, "Of course, the solar system is already at our disposal, and with the use of multiple space folding, our footprints may be able to advance far, but it is not enough to support us to become a real interstellar race, so you still need to work harder."
