Chapter 644: Chapter 539: Everything is changing, only the speed of light is constant!_2
Steg, who had previously scoffed at Jeffrey, fell silent for a mont, then also nodded.
“Well said, the developnt of magic studies and the perfection of theories cannot happen overnight, and we must not affirm everything just because of the authority of the proposer. Just like Chairman Lynn’s postulate in the theory of relativity about the constancy of the speed of light, I think that it simply doesn’t accord with logic. I can even think of over a thousand thods to refute it!”
The wizards gathered here nodded as well, for they had co together today to inquire about this very issue from the Star of Magic.
However, just as Steg had finished speaking, another voice rang out from inside the manor.
“Oh, really? I wonder what those thods might be? I would like to hear about them!”
The previously confident Steg’s face changed instantly, and he imdiately turned his head towards the direction of the manor.
The person who arrived was naturally Lynn, accompanied by a majestic beast over three ters tall. It was Mutuo who had just taken its stand at the gateway, barring everyone from entry.
All the grand wizards present had co to refute the theory of relativity, but upon truly seeing Lynn, so began to have second thoughts, starting to ponder whether there was sothing amiss with their own theories.
There had been no shortage of those who believed they had identified theoretical flaws and could disprove the Star of Magic, thus making a na for themselves.
After all, everyone knew that Chairman Lynn had no scruples when it ca to discussions about magic studies and had even openly stated on multiple occasions that he welcod anyone to prove his theories wrong with rigorous theories and precise experintal results!
Yet, to this day, no one had been successful, and the number of those who had been figuratively slapped in the face was countless.
Even the stellar elental orbital model, which was the only theory proven wrong, had been corrected by Lynn himself with an even more fitting quantum probability cloud theory—indeed, to this day, many wizards still firmly believed the stellar elental orbital model was the truth because it was just too perfect.
Despite having many concerns, they had co all the way and it wouldn’t be good to turn back now. Steg braced himself and spoke up. “Chairman Lynn, regarding your latest publication on the theory of relativity released today, I have many doubts and questions that I wish for you to clarify!”
“Since it is a discussion about academic matters, let’s co inside and talk,” Lynn replied without any intention of making it difficult for Steg. He had anticipated that releasing the theory of relativity would inevitably cause a huge stir in the academic world.
The microcosmic phenona do indeed seem difficult to understand from a macrocosmic perspective.
Steg then breathed a sigh of relief and stepped into the manor along with Jeffrey, Sanchez, and others.
Lynn led them to the optical laboratory, and Steg looked around the room, which was filled with many magical instrunts with nas he could not pronounce, all seemingly exquisite.
“Let’s discuss your questions here, one by one. We might as well start with the principle of relativity!” Lynn said directly.
The wizards exchanged glances and Steg was the first to speak. “In your paper, you said that all inertial fras of reference are equally valid, that none is more special than another. So if I am running towards you now, it can also be interpreted as you running towards , is that correct?”
The equality of reference fras in the principle of relativity was the first issue that confused him,
“No, before understanding this concept, I need to explain what an inertial fra of reference is!” Lynn shook his head. “It refers to the situation where an object maintains relative rest or moves at a constant speed along a specific path. Without external forces causing a change, it will continue to move at its current velocity.”
“For example, all of you standing still right now can be considered inertial fras of reference inside this planet.” As Lynn spoke, he pulled out a silver coin and threw it sharply. “If I am the fra of reference, then it could be said that this silver coin is moving forward at a speed of fifty ters per second!”
“Does this have any significance? Regardless of whether it’s from the perspective of an inertial reference fra, isn’t its speed and direction the sa?” a senior Wizard asked in surprise.
“No, without this reference fra, we might as well say that the speed of this silver coin is thirty kiloters per second!” Lynn shrugged and said with a smile.
Steg and the others were taken aback for a mont, then turned to look at the silver coin nailed to the wall and began to ponder with furrowed brows.
A senior Wizard who had studied astronomy quickly caught on. “This is the speed of the Eternal Star orbiting the Sun!”
Because they were inside the Eternal Star, if they took the Sun as the reference fra, they were indeed moving at a speed of thirty kiloters per second around the Sun.
“But, that doesn’t seem quite right either?” Steg said thoughtfully. “It is the Eternal Star that is moving, the speed of this silver coin is still fifty ters per second.”
Lynn retorted, “Suppose you are sitting on a high-speed train, not moving yourself, but to people outside the station you are still moving away from them at high speed.”
Steg was suddenly at a loss for words and unable to respond for a good while.
Lynn went on to explain. “Without an inertial reference fra, distinguishing up from down or north from south is utterly aningless. For instance, inside the Eternal Star, to people living in the northern hemisphere, north is up, while for those in the southern hemisphere, south is up!”
“The reason we can clearly distinguish directions now is because gravity is pulling us down to the ground, making the center of the Earth ‘down’, and the other directions are naturally discerned as well!”
In just a few sentences, Lynn had clarified the necessity of inertial reference fras and why reference fras are equated, and since all present were senior Wizards, they naturally had no difficulty understanding.
But this gave rise to a second question.
“Speaker Lynn, I understand what you an, but forgive for being blunt, your theory of the constancy of the speed of light seems to conflict with the concept of the equivalence of reference fras,” Steg spoke up again.
“Suppose we release a laser magic inside the Eternal Star, then as seen from the star, shouldn’t the speed of light be the speed of its revolution plus the speed of light?”
The example Steg brought up was akin to the silver coin Lynn had thrown, using Lynn’s own words as a rebuttal.
Lynn was naturally not going to be tripped up by such a minor issue, and replied with an unperturbed smile. “How do you think waves propagate? And what factors affect their speed?”
When Steg saw Lynn shifting the topic, he frowned slightly but still answered. “The transmission of waves naturally relies on a dium, as for their speed of propagation…”
“The speed of chanical waves depends solely on the dium; they are not affected by other factors!” Lynn explained. “For example, sound is a type of chanical wave!”
“Under normal temperature and atmospheric pressure, it propagates at a speed of three hundred and forty ters per second. Its speed will not increase just because you are running and shouting at the sa ti! An example of this is when you use Thunder Magic—the sound may arrive after the lightning because it’s much slower than lightning and isn’t affected by external forces.”
“Therefore, no matter what state you are in, as long as the dium doesn’t change, any asurent of chanical waves within an inertial reference fra, in any position or angle, with instrunts, will inevitably yield a stable and constant value!”
Jeffrey suddenly saw the light and exclaid excitedly. “Light is also a wave, a rather special electromagnetic wave that also possesses certain wave characteristics, so asuring its speed is actually asuring its rate of propagation in a certain dium!”
Lynn nodded with a smile, knowing this, the mystery of the constant speed of light was half understood, although the remaining half was the most difficult to understand!
