Greetings, Mister Principal: Absolute time and space

The banquet to welcome Reiner back was held as scheduled, and life at Crescent College returned to its original calm state.

Reiner paid close attention to the progress of the ruins. Every week, he received reports from the Rainbow Tower, recording every detail of the excavation of the ruins. Unfortunately, after they left, the excavation work of the ruins continued. There is still little progress, perhaps because this ruins has been lost in the long river of time for too long, and all valuable things have been wiped out.

Turning his attention back from the ruins report, Reiner saw the latest issue of the academic journal.

The cover of "Truth" is an atomic model, and what is different from the previous one is that the nucleus of this atomic model is no longer a simple ball, but is composed of particles of two different colors.

Opening "Truth", the first article Reiner saw was a paper on neutrons and protons.

The first author of this paper is Reiner Ingle, and the collaborators include several legendary mages and high-level mages. The most eye-catching one is one of the names.

Oriolus von Hohenheim.

Without announcement or news, Master Hohenheim returned to people's attention in the form of a paper.

Although the content of this paper is very shocking to the mages, more people are still focusing on the news of Master Hohenheim's return.

Not only the Tower of Rainbow, all major media across the continent are rushing to report on Master Hohenheim. Some who can get first-hand information follow and report on Master Hohenheim’s movements after returning to the Tower of Rainbow. Other media can only list Master Hohenheim's achievements one by one and make some special topics that are better than nothing.

Reiner's "Daily Prest" has such a topic, but compared to the achievements of Master Hohenheim, the topic of this newspaper focuses more on overthrowing the theory of the four basic elements. After all, Reiner is half a Priest, so he naturally needs more coverage.

Taking his eyes away from the newspaper, Reiner turned over the paper and saw the following articles. The title of one of the papers caught Reiner's attention.

"Some Thoughts on Absolute Space-Time and Aether", author: Isharis Alberton.

"Absolute time and space?"

Reiner quickly began to read this paper written by the legendary mage. The starting point of the paper was the inconsistent phenomenon of time flow experienced by the mages in the ruins of Eliot's demiplane. Lord Alberton tried to find this The reason for the phenomenon, because he is good at the law system and has done a lot of research on force and space, he discussed a concept, that is, absolute space and time.

The concept of absolute time and space mentioned by Mr. Alberton is actually inherited from the recognized principle of the ancient Magic Empire, that is, the laws remain unchanged under any circumstances.

This is easy to understand. The truth that mages are committed to exploring is a formula that can explain any phenomenon. This formula can naturally adapt to all situations, and if the environment changes, a magic law will change accordingly. , then this law is not universal.

Based on this principle, two arguments can be derived, the absoluteness of space and the absoluteness of time. This is also easy to understand. Since the laws are unchanged and applicable in various situations, then the laws are used to describe Space and time must also be unchanged. One meter is one meter no matter what the situation is, and one second is one second no matter what the situation is. For this reason, such as Alberton's second law, F= A formula like ma can ignore various complex situations and achieve the most essential rules.

This is the principle of relativity between absolute space-time and laws. Described in relatively formal language, it means that the mathematical form of laws will not change in any reference system.

As for the issue of ether drift, Lord Alberton put forward a hypothesis, which was first based on the inference that the speed of light is limited.

The inference that the speed of light is limited was discovered by astrology mages when they observed changes in the stars, because it is known that the orbit of the planet is an ellipse, and as the distance between the planet and the sun changes, the cycles of certain star changes will change, and According to Regens' three laws, the rotation time of the planet is fixed, which means that it takes time for the star changes observed by the mages to be transmitted to the planet. The farther the planet is from the observation object, the longer the light propagation time. On the contrary, the shorter it is, which is contrary to the past belief that the propagation of light is instantaneous. The Newington-Holland equations were proposed to calculate the speed of light, which also verified this inference.

Lord Alberton assumes that there are two moving observers A and B in the ether. They are separated by a certain distance and synchronize the watches in their hands through optical signals. Since they both think they are stationary, they are synchronized. The clock only needs to calculate the time it takes for the signal to travel.

But if there is a third observer C, who is stationary relative to the ether, then in his observations, the two moving observers A and B do not actually synchronize their own watches, but only Received the time of your location.

At the same time, due to the definition of ether ~IndoMTL.com~ people cannot feel the flow of ether, so they do not know whether they are moving, then all behaviors that use light to calibrate time will have errors.

According to the principle of relativity of laws, this should not happen, because it means that the laws change during motion.

Or mages can choose to abandon the ether doctrine, but even so, similar problems will still arise under certain circumstances. Starting from the ether drift experiment, the foundation of the entire magic is shaking in the wind and rain.

If the discovery of protons and neutrons in atomic nuclei gave mages hope of penetrating into the microscopic world, then the drift of ether and the problems it derived gave mages a sense of despair.

Because for mages, formulas and theorems are like tools for understanding the world, and they are precious crystallizations gained from exploring the world. If the principle of relativity of laws did not exist, then the towers built by mages for thousands of years would It will collapse in an instant, because all known laws are not fixed and can be changed. The world will change from knowable to unknowable, which means that the mages' exploration will ultimately yield nothing.

This is no less than the memory from the last era that drove Master Hohenheim crazy. If it weren't for the fact that Lord Alberton's paper did not delve too deeply into the loopholes of the principle of relativity of laws, plus this There are not many people doing basic theoretical research, which is likely to lead to large-scale academic panic. ...
