This is currently the most likely way humans can think of to reach another coordinate faster than the speed of light.
Under current scientific exploration, the speed of light cannot be surpassed, and the nearest planet in the universe that humans can detect with an environment similar to the earth is sixteen light years away from the earth. One light year is 90,000
More than 400 billion kilometers, close to 10 trillion kilometers, which means that the planet that has been detected so far has an ecological environment most similar to that of the Earth is more than 150 trillion kilometers away from the Earth.
At present, the fastest aircraft developed by humans can reach a speed of more than 70 kilometers per second, which is only one-fourth thousandth of the speed of light. This means that an aircraft manufactured with current technology cannot reach a place sixteen light years away.
It will take more than 60,000 years to create a super Earth, which is much longer than the history of human civilization.
Even if the speed of light could reach five thousandths of the speed in the movie The Wandering Earth, it would still take 3,200 years to complete this journey, which is almost the length of the history of Chinese civilization.
Therefore, even if we can find a closer planet with an Earth-like environment for humans to expand their territory in the cosmic ocean, it is still wishful thinking given the current level of science and technology. The most important thing is that it is limited by the speed of the aircraft.
Under such circumstances, the space folding theory emerged, and according to current scientific understanding, the distortion and folding of space do indeed exist. Of course, all of this is currently only a theory or even a conjecture, and no one has ever experienced it.
space folding, but this theory is considered to be real.
First, make sure that space folding really exists. Then, if space folding becomes controllable by technological means, the increase in "speed" will be completed, surpassing the speed of light in time - in fact, the speed of the aircraft does not increase during space folding.
, only the space has changed.
This concept appears in many science fiction works. For example, the most famous one is Marvel's Guardians of the Galaxy. Star-Lord and others rely on the so-called jump engine to straighten the space in front of the aircraft and use the space to retract.
Achieving the speed of light beyond the speed of light. This may seem to be the opposite of the method of achieving space folding, but it is actually the same thing. They both use distortion and deformation of space to achieve the speed of light beyond the speed of light.
Cheng Yu, as an originally very promising finance student, naturally knew something about these theories, so when he saw the animation of the redeemable item, his first reaction was space folding.
In my mind, I gently clicked on the icon that was still repeating the map folding, and a translucent dialog box slowly appeared above it.
The five words in the dialog box completely confirmed Cheng Yu's guess.
"Teleportation".
Just these five words.
The concept of teleportation should have first appeared in some supernatural works, which were often mythical or magical works, not science fiction works. When the concept of space folding appeared, teleportation was also
The explanation becomes displacement achieved using space folding.
At this moment, according to the animation, the explanation of this instantaneous movement undoubtedly means space folding. Or, to be more precise, the Shenhu system used the concept of space folding to explain the brand-new function it gave Cheng Yu.
ability.
Clicking again, the system popped up a translucent dialog box, which said: Please confirm whether to redeem the teleportation spell?
Below are naturally two buttons for confirmation and cancellation.
Cheng Yu took a look and found that the points required to redeem teleportation spells were slightly higher than other items, but they only required twenty points. In order to have a deeper understanding of this redeemable item, Cheng Yu could only redeem one first.
After selecting Confirm, the exchange is successful, and the system pops up a translucent dialog box again.
"A high-level teleportation technique, a one-time consumable. After use, the host can achieve a teleportation with a straight-line distance of no more than 6,400 kilometers. This movement distance can be used superimposed..."
Seeing this, Cheng Yu frowned slightly.
The number six thousand four hundred kilometers is a little strange, but Cheng Yu soon realized that this is approximately the radius of the earth. The average radius of the earth is about six thousand three hundred and seventy one kilometers, and this six thousand four hundred kilometers is obviously
Implemented for this value.
What does it mean to be superimposed? Could it be that by exchanging two teleportation spells, they can be superimposed and used to obtain a movement distance that directly penetrates the earth?
Cheng Yu continued to look down.
"And the arrival point is only the surface of the host's planet. When using it, you need to specify the precise longitude and latitude coordinates of the arrival point. If the straight-line distance between the two places exceeds the maximum movable distance, the consumable will be invalid and will not have other effects on the host.
.”
Cheng Yu could easily understand this.
The earth is a sphere, so using space folding to teleport is essentially to make a secant line of the earth's cross section between the starting point and the end point. Space folding will not be performed in an arc. On a sphere
On the cross section, that is, on a circle, the longest secant line is the diameter of the circle, which is twice the radius - of course, the line equal to the diameter cannot be called a secant mathematically.
If Cheng Yu needs to teleport, it will actually be done at two points of this secant line. Only in this way will it be a straight line. Therefore, if the length of this secant line exceeds 6,400 kilometers, Cheng Yu will
Plunging headlong into a certain location inside the earth is obviously contrary to the rules of teleportation, which requires that the destination is only on the surface of the planet where the host is located. Such teleportation is basically equivalent to being buried alive.
Based on this, Cheng Yu was quite grateful that the God Digging System judged such behavior as invalid, and it was just a waste of a teleportation spell. Otherwise, as long as he failed to teleport once, he would die directly from this stupid behavior.
To be on the safe side, there will definitely be no problem if Cheng Yu exchanges two teleportation spells every time before teleporting. In that case, even if he teleports from Mount Everest, the highest peak in the world, to the opposite side of the earth, it will not be a problem.
Even though the distance is increased by less than nine kilometers, it will not affect the fact that his final teleportation point is above the earth's surface.
But for some reason, Cheng Yu always feels that this setting is a bit cheating. You can either directly exchange forty points for a teleportation spell, and this teleportation spell can allow Cheng Yu to teleport from any point on the earth to any point in the distance.
Is that enough? Why do you need to do something like teleporting to the radius of the earth with twenty points?
Cheng Yu frowned slightly. This kind of superfluous thing was obviously not something that the God System would do. After all, in order to avoid wasting the teleportation skills redeemed, Cheng Yu could have exchanged two teleportations each time.
Use the techniques in combination to ensure everything.
Soon, Cheng Yu gained insight into the subtleties of the system's settings.
The teleportation spell is redeemed with twenty points. Once it is judged to be invalid by the system, it is equivalent to a waste. For such waste, points will be deducted during the normal life span.
Cheng Yu estimated that for this kind of waste, another 20 points would be deducted from the guarantee as punishment. This is because the system is trying to trick people!
At the same time, Cheng Yu thought that if he used two teleportation spells to superimpose each time, when the secant line was less than or equal to 6,400 kilometers, he would have wasted twenty points. This would still be
What a move to deduct points!
Isn't this too boring? Just to deduct points from me, what's the point?
Cheng Yu was really speechless at the system's fussy behavior.
But he soon noticed a hint of danger. If the penalty for this waste was just twenty... well, even a hundred points would be a drop in the bucket for Cheng Yu, who now has a lot of points.
No pain or itch. Moreover, Cheng Yu has a large number of non-picking time periods and unrestricted time periods. During these time periods, the system will not punish his wasteful behavior. Then, as long as Cheng Yu has a little control
If you think about the remaining non-tapping time period or the unrestricted time period, which time will be consumed every time you use the teleportation technique, then won't the system never be able to punish Cheng Yu? Then such a setting still makes sense.
What?
Obviously, the system will not make meaningless actions. Since there are all kinds of contradictions here, it can only mean that the system has other explanations for this rule.
The length of a conversation has almost no meaning to Cheng Yu now. He hasn't actively sought an explanation from the system for an unknown amount of time. The pattern of the small speaker has also accumulated countless conversations.
It’s been a long time.
In order to thoroughly understand the rules for using this teleportation technique, Cheng Yu decided to clear the previously accumulated conversation duration.
After using the conversation duration, the system sound appears.
"The host has not used dialogue time for a long time. Is there anything I can do for the host?"
Damn, this system is getting more and more nifty.
Cheng Yu didn't bother to complain and asked directly: "When I use the teleportation spell, the distance I need to teleport exceeds the longest movable distance of a teleportation spell, and the system determines that the consumables are invalid. Is this right?
Will it result in a waste assessment for me?"
"The host's guess is good. This will indeed cause the system to make a wasteful assessment."
"So points will be deducted?"
"Yes."
"How much will be deducted?"
The system obviously stagnated for a moment. Although this time was very small, Cheng Yu was still keenly aware of it.
There is a pit here!
If there are no pitfalls and only twenty points or even one hundred points are deducted, the system will never stagnate...
Cheng Yu suddenly thought that he had now reached the highest level of the system. The rewards he received were no longer restricted by the one hundred points cap, which almost meant that the punishment he received would not be capped by one hundred points.
Limited by points.
The system’s answer also confirms this.
"Wasting hard-earned points is the behavior most hated by the system. Wasting the system to exchange items is equivalent to wasting points. Therefore, every point wasted will result in a penalty of 100 points deduction."
A hundred points will be deducted for wasting one point? These twenty points, damn, two thousand points!
The co-authoring system is waiting for me here! You old Yinbi!
If it were in the past, Cheng Yu would have cursed loudly, but now he would no longer waste his energy on useless arguments with the system. A curse would be enough when he was shocked.
"Haha, you guys are really cruel. If I hadn't realized this, I'm afraid I would have easily deducted at least two thousand points from you."
"The host is wise." The tone of the system that is neither yin nor yang is becoming more and more mature, and it is indeed becoming more and more like an old yinbi.
"Correspondingly, if I don't consider the straight-line distance between the two points I need to teleport, and use two teleportation spells to superimpose each time, once the moving distance is actually smaller than one teleportation spell,
If the effect distance is too high, then the system will judge that a teleportation spell was wasted."
"The host is wise."
A slight smile appeared on Cheng Yu's face, and he asked again: "So, even if I am in the no-digging time period or the unrestricted time period, the waste of points will not be protected by these two time periods. The system
It will still be judged that I wasted points, right?"
The system came to a standstill again, and soon, it made a sound like gnashing teeth: "The host is really getting wiser and wiser, and you have thought of this. Then please use the teleportation technique every time in the future.
When the time comes, let’s do some math problems.”
Cheng Yu responded with a slight smile and didn't take it too seriously.
If this was just a math question, it would not be difficult for a top economics student like Cheng Yu. The system would not come up with such an elementary question to embarrass Cheng Yu.
Although the earth is said to be a sphere, in fact, no place on the earth's surface is a regular arc, but has highs and lows. Even the earth is not a regular sphere. In this case, you want to calculate the absolutely correct
Numerical values are nothing more than wishful thinking.
But after Cheng Yu realized that the system had become an old yinbi, he had already thought of a solution to this problem.
He only needs to roughly calculate the length of the secant line between the two points where he needs to teleport. If it is much greater than 6,400 kilometers, then there is no doubt that he needs to use two teleportation techniques to superimpose.
And if it is much less than 6,400 kilometers, it will be easier to handle.
The key to the problem is actually that when the value was calculated, it was very close to 6,400 kilometers. This is when Cheng Yu needs to be careful.
But Cheng Yu actually had other ways to avoid this problem.
If the secant of a standard circle is equal to or less than its radius, this means that the length of the arc between these two points is equal to less than one-sixth of the circumference of the circle. As we all know, the circumference of the earth is about 40,000 kilometers.
This also means that as long as Cheng Yu wants to teleport to a distance less than 6,600 kilometers, he can basically use a teleportation technique to achieve it.
Or simply set this value a little lower, for example, 6,400 kilometers, so that he will never be judged as having teleportation invalid.
And if the place Cheng Yu needs to go is close to 6,600 kilometers from his current location, he can first move more than 200 kilometers in the direction of that place, and then use a teleport to complete it. China
It's so big, no matter which direction he goes, he has enough space to adjust his position. In this way, except for the destination that is definitely more than seven or eight thousand kilometers away, Cheng Yu can almost use a teleportation to complete it.
This may waste some time, but it will never result in a direct waste of points.
There is no need to worry about wasting time. Cheng Yu has enough time periods to ensure that he will not be punished by the system.
"Okay, just memorize Sikuquanshu silently until the conversation time runs out." Cheng Yu waved his hand.
