The banquet to welcome Reiner back took place as scheduled, and life at Crescent Academy returned to its original uneventful state.

Reiner kept a close eye on the progress of the ruins, and every week, he received reports from the Rainbow Tower, detailing the excavations of the ruins, but unfortunately after they left, the excavation of the ruins still made little progress, perhaps because the ruins had been lost for so long that everything of value had been lost.

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

The cover of Truth is a model of an atom, but unlike the previous ones, the nucleus of this model is no longer a simple sphere, but is made up of two particles of different colors.

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

The first author of this paper is Reiner. Ian Gray, and the collaborators include several legendary mages and high-level mages, most notably one of them.

Orioles. Feng. Hohenheim.

There were no announcements, no news, and Master Hohenheim returned to the limelight in the form of a thesis.

Although the content of this paper was very shocking to the mages, more attention was still on the news of Master Hohenheim's return.

Not only the Rainbow Tower, but also the major media across the continent have rushed to report on Master Hohenheim's affairs, some of them can get first-hand information to follow and report on Master Hohenheim's movements after returning to the Rainbow Tower, while other media can only list Master Hohenheim's achievements one by one, and do some special topics that are better than nothing.

Reiner's "Daily Priest" has such a feature, but compared to the achievements of Master Hohenheim, the focus of this newspaper's special focus is more on Reiner, who overturned the theory of the four basic elements, after all, Reiner is also half Prest, so it is natural to report more.

Reiner, retracting his gaze from the newspaper, flipped through the paper and saw the next few papers, one of which caught Reiner's attention with the title.

Some Thoughts on Absolute Space-Time and the Aether, by Isaris. Alberton.

"Absolute space-time?"

Reiner soon began to read the paper written by the legendary mage, and the starting point of the paper was the inconsistency of the flow of time experienced by the mages in the ruins of the Elliot half-plane, and Lord Alberton tried to find the cause of this phenomenon, because he was good at the law system and had a lot of research on force and space, so he discussed a concept, that is, absolute space-time.

The concept of absolute space-time referred to by Lord Alberton is actually inherited from the accepted principle of the ancient Magic Empire, that is, the law remains unchanged in all circumstances.

It is easy to understand that the truth that the mages are committed to exploring is a formula that can explain any phenomenon, and that formula is naturally adaptable to all situations, and if a law of magic changes as the environment changes, then the law is not universal.

Based on this principle, two arguments can be derived, space absoluteness and time absoluteness, which is also easy to understand, since the law is constant and applicable in all situations, then the space and time described by the law must also be unchanging, a meter is a meter no matter what the situation, and a second is a second no matter what the situation, and it is precisely because of this that formulas such as Alberton's second law, F=ma can ignore all kinds of complex situations and reach the most essential law.

This is the principle of absolute space-time and law relativity, which is described in relatively formal language, that is, the mathematical form of the law does not change in any frame of reference.

As for the question of aether drift, Lord Alberton put forward a hypothesis, which is based on the inference that the speed of light is finite.

The inference that the speed of light is limited is discovered by the astrological mages when observing the changes of the stars, because the orbit of the known planet is elliptical, and with the change of the distance between the planet and the sun, the cycle of certain star changes will change, and according to Regens's three laws, the operation time of the planet is fixed, so this means that it takes time for the astrological changes observed by the mages to be transmitted to the planet, and the farther away the planet is from the object of observation, the longer the light propagation time, and vice versa, the shorter it is. This is contrary to the belief that the propagation of light is instantaneous, and the Newington-Holland equation calculates the speed of light, which also confirms this inference.

Lord Alberton assumed that there were two moving observers A and B in the ether, separated by a certain distance, and synchronized their watches with optical signals, and since they both thought they were stationary, the synchronous clock only needed to calculate the time it took for the signal to be transmitted.

But if there is a third observer, C, who is stationary relative to the aether, then in his observations, the two moving observers A and B are not actually synchronizing their own tables, but simply receiving the time of their own location.

At the same time, due to the definition of aether, people cannot feel the flow of aether, so they do not know whether they are moving or not, so all the use of light to calibrate the time will be incorrect.

According to the principle of relativity of the law, this should not be present, because it means that in motion, the law changes.

Or mages can choose to abandon the aether doctrine, but even then, similar problems can arise in certain situations, starting with the aether drifting experiment, and the entire foundation of magic is shaking through the storm.

If the discovery of protons and neutrons in the nucleus of the atom gave mages hope to go deeper into the microcosm, then the aether drift and the problems it raises have given them a hint of despair.

Because for the mages, formulas and theorems are like tools to understand the world, and they are valuable crystallization obtained from exploring the world, if the principle of relativity of laws does not exist, then the towers built by the mages for thousands of years will collapse in an instant, because all known laws are not fixed, they can be changed, and the world will change from knowable to unknowable, which means that the mages' exploration will eventually come to nothing.

This is no less than the memory from the last era that drove Master Hohenheim into madness, and if it weren't for the fact that this paper by Lord Alberton did not delve too deeply into the loopholes in the principle of relativity of laws, and because there were not many people who studied this basic theory, it would probably lead to a large-scale academic panic.
