Lindbergh's voyage between the stars with tears is certainly a necessary measure for Sith teaching, but it is also a business need. He was assigned to the maintenance of the Plantagenet by Commander Hadwin, and now he is going to the dimensional fleet to discuss the matter.

"Teacher, where is the dimensional fleet moored?" Tears were in high spirits, she had always been proud to be a member of the "alien organization with a huge conspiracy", and now she could see it with her own eyes, and she couldn't hide her excitement, "Is it on Mars?" ”

"Mars?" Lindbergh continued to stare at his phone, looking up the legal terms, and casually replied, "Didn't we just fly?" ”

"What! Why don't you even remind me. Can you fly back, I want to see Mars! ”

"Don't make a fuss." Lindbergh suppressed the disciple's nonsense, "Sit down, it's time to speed up." ”

"But where the hell does the dimensional fleet stop?"

A naïve girl, the limit of imagination is only to Mars.

"Our destination is not in this universe." Lindbergh sat in the captain's seat, and saw that the gravitational test data was gradually stabilizing during the monitoring, and immediately ordered the main control logic core, "The warp engine stops, the inertia protection force field is turned on, and the time-lapse engine is warmed up." ”

With the order to sail, the starry sky outside the Plantagenet string window changed, and the starlight, which had been distorted in the curvature field, returned to normal.

On the bridge, Tears and Lucie suddenly felt light, and the unfamiliar rules of physics enveloped them.

"It is troublesome to start the chrono engine in the material universe, and before the speed of light is exceeded, the strong acceleration will tear apart any mortal body, so an inertial protective force field is needed to balance the force on the entire ship." Lindbergh's absent-minded explanation, the reason why he said absent-mindedly, was because he was speaking completely into his new fruit phone.

"Wait a minute, isn't it impossible for objects to accelerate to the speed of light?" Zuotian Tears surprised her teacher, and she actually remembered the most basic physics course, "Didn't I say in class that the speed of light is an absolute scale, and there is no speed in the universe that exceeds the speed of light." ”

"Good!" Lindbergh felt that the tears were saved, and looked up from his phone, "There is indeed no existence in the universe that exceeds the speed of light. But the premise of this definition is 'in the universe', in other words, if an object exceeds the speed of light, then it no longer belongs to the universe, which is the principle of superspace. ”

"I don't understand." Tears pitifully admitted.

"Why do you think objects can't exceed the speed of light, or why is the speed of light the absolute scale of the universe?" Started talking to the phone again.

"Uh, that's it......"

Tears pointed at each other in embarrassment, and peeked at her sister Lucieu, the elf was even more dazed than her, and it seemed that she could not count on it. I really hate asking questions in class anytime and anywhere.,It's still such a clueless question.。

"It's probably the definition of a scientist, it's like an axiom, it doesn't need to be discussed, hahaha." She played a trick.

"The speed of light is not an axiom, in fact, it is always slowing down." Lindbergh, of course, didn't expect his disciples to answer. The controversy about the speed of light has accompanied almost the entire second phase of technological civilization, and even on the home planet of the Sith, there have been various theoretical hypotheses.

But just as people in the Middle Ages would never again believe that the earth was round – until seeing is believing.

So, Lindbergh needs to have someone see it for themselves before he can continue with the following explanation.

"Then ......" Lindbergh saw that his disciple was sitting down obediently and nodded, "Chrono engine, ignition!" ”

The Plantagenet's crew erupted into a roar, but the Chrono Engine was not a fuel-injected engine, and it didn't pull out an exaggerated tail flame at the stern of the ship, as it would have been when the Plantagenet was cruising with its warp engines on it. In space, the Plantagenet can cruise at tens of billions of times the relative speed of light, but in reality, this is nothing more than a misunderstanding caused by the characteristics of curvature navigation.

No curvature engine can make a starship exceed the speed of light on an absolute scale, even if the warp engine installed on the Plantagenet has a curvature field of an incredible 10.0 - this curvature can theoretically reach any coordinate in the universe in an instant.

The principles of the chrono engine and the curvature engine are very different, the former is field acceleration and the latter is field distortion. When cruising on the physical plane, most travelers opt for a warp engine because it is smooth and safe.

The Chrono Engine can also be used in the material plane, but it must be equipped with an inertial force field balancing system, otherwise no mortal matter can withstand the acceleration of the speed of light. In addition to the expensive inertial force field balancing system, the stability of the Chrono Engine itself is very questionable, and its failure rate is a well-known meme in the multiverse.

Lindbergh himself, along with the Plantagenet, was shipwrecked in the universe during a misguided chrono voyage and had to send a distress signal to the nearest dimensional fleet.

So, from an angle that Zotian Tears and Lucieu couldn't see, Lindbergh was deeply worried. The so-called once bitten by a snake for ten years is afraid of the well rope, he is worried that if something fails in the chrono engine, God knows how the tears that can't return home will torture him.

The only consolation is that if you really get lost in time and space, you can avoid Commander Hardwin—probably.

Lindbergh's cranky thinking has no metaphysical effect, and the Plantagenet logic master corrects the chrono elements, smoothly activates the acceleration field, and gradually increases the energy supply.

Under the protection of the inertial force field balancing system, the three members of the Plantagenet did not personally feel the terrible acceleration of one hundredth of a C per second. But the universe outside the string window began to change incredibly in the visual range.

Saten Tears noticed that the more ancient and unchanging brilliant starlight, which originally served as the background of the universe, gradually changed color. At first sky blue, then ice blue, and they were all bright white with a few reddish tinges. But in just ten seconds, the starry sky turned into a black velvet adorned with beautiful sapphires.

"Kepler Blueshift." Lindbergh explains aloud, "When we approach an object at high speed, its spectrum shifts towards the blue end. ”

"Teacher, what about our course?" Although the tears are very excited, there are also worries that they will not be able to go home. She hopes to write down whether Mr. Kobayashi "turns left" or "turns right", so that when she really gets lost, she can take "Uncle Stupid" and her sister home.

Tears, you're too confident in your long legs! Even if your legs were a hundred times longer, it would be impossible to cross such a terrible astronomical distance.

"Chrono jumps don't need to focus on the course of the material plane, just like if you want to fly into space on Earth, you don't need to choose a direction on the ground." Lindbergh reminded, "You need to pay attention to the present. ”

At this time, on the accelerometer, the scale has risen to 0.1C, and the blue stars in the sky are gradually distorted, not only the original color that is getting bluer and bluer has returned to white, but also the edges of the stars themselves have begun to blur, and finally, even one by one, the tail of the radiation has been dragged out.

In an instant, the stars in the sky suddenly burst out, turning into countless dazzling rays, centered in the direction of the bow of the Plantagenet, and quickly swept backwards.

The Plantagenet is like walking through a rain of swords. The blinding light made Tears and Lucieux close their eyes.

"What is this?" Lucie asked cautiously, she had expected Sister Tear to ask this question, but unfortunately Tear was rubbing her eyes as she name it was, wiping away tears stimulated by the surge of starlight with a tissue.

Unexpectedly, Lindbergh answered the question, but his voice was not directed at Lucie.

"It's a light barrier, a phenomenon when the speed is about to break through the speed of light. At the beginning of the Great Cosmic Age, this barrier had blocked countless ancestors. As the ship approaches the speed of light, its mass tends to increase infinitely. Therefore, even with abundant acceleration power, the spacecraft itself will collapse in a higher and higher gravitational field. ”

"As I said before, when you get close to the speed of light, the mass is infinitely magnified." Tears wiped his eyes.

"You have to see the nature of the speed of light." Lindbergh's hand pointed forward, "Or what do we catch up with when we really reach the speed of light." ”

After saying this, the ominous shaking on the Plantagenet became more and more frequent, making people feel terrified. At the same time, the sword rain outside the string window became denser and thicker, and finally turned into a light curtain that could not be seen directly. The ship had to raise a photon barrier to ensure that the members would not be burned through by the raging rays.

"What we caught up with was the cosmic microwave radiation background, or more figuratively, the shock wave of the Big Bang."

In the infinite light, Lindbergh raised his hands and proclaimed loudly like a third-rate magic stick: "This is the light of creation, the Higgs field that spreads outward with the Big Bang, which gives mass to existence, making energy a reality of a material plane."

We caught up with the light of creation, and we will inevitably be affected by it, and in such a strong Higgs field, the kinetic energy of the ship is directly evolved into the mass of the body. This is the nature of the speed of light, the reason why the speed of light cannot be surpassed. ”

"Oh." Tears echoed absentmindedly, "Then what should we do." ”

She's just a high school student, and even though she's been learning "alien technology" with Mr. Kobayashi for more than a year, she's actually practicing the way of the Sith in order to beat people as handsomely as Mai Trin.

She is more interested in "fashion" and "gossip" than "quality" and "energy". Little girl, you can't ask too much of her.

Lindbergh was very clear about his disciple's behavior, and he couldn't help but sigh. But the explanation doesn't stop:

"No matter how amazing it is, the Higgs field is also a material field, and its speed is still limited to the speed of light. Therefore, as long as our acceleration exceeds the speed of light, then even the light of creation cannot stop us. ”

Driven by the chrono engine, the acceleration data on the screen continued to climb, and Lucieu squinted her eyes to take a closer look, and the data at this time happened to be over 1.0C/S^2.
