Cultivation: I Have Studied Abroad in the Modern World

Chapter 263: Chapter 152: Experimental Tips

Upon hearing Tang Mudao say he had a way, the other four couldn’t help but turn their attention to him.

Tang Mudao pondered: “I mentioned to you before, Zheng Fa, our major job in astronomy is to collect various signals from the universe, be it X-rays, rays of light, or even microwave signals—in the end, they’re all observations of electromagnetic waves. These observations often last many years, resulting in a large volume of corresponding records.”

Zheng Fa nodded and waited for him to continue.

“So, theoretically speaking, many observatories would have records of electromagnetic signals from the day of each solar term—except these electromagnetic waves are usually regarded as noise.”

“I’ll check the public data from a few observatories; I should be able to get the relevant records.”

Upon hearing this, Zheng Fa couldn’t help but gratefully say: “Then we will have to rely on Professor Tang!”

Tang Mudao waved his hand and headed to his room, probably to search for some documents.

However, Old Man Bai asked: “With so many observatories and such a variety of signals received, how can we determine which signal is the one we’re looking for?”

It was a good question.

Electromagnetic waves are too common—almost infinite. Each observatory receives a vast quantity of electromagnetic signals at any given moment.

On the other hand, observatories are scattered across various regions, whether they can observe the special signals that Zheng Fa is hoping for is another matter.

Of course, they didn’t know, but Zheng Fa understood—

The Xuanwei Realm is ultimately not quite the same as the modern world. Although both have the concept of solar terms, the connotations may not be the same.

Therefore, whether this kind of special electromagnetic wave exists in the modern world is a more critical issue.

This is somewhat akin to looking for a needle in a haystack.

“There’s one method,” Zheng Fa said.

“If my hypothesis is correct, then we can make a deduction—on the day of the solar term, there will be special electromagnetic waves.”

“And such electromagnetic wave signals will not appear on non-solar term days.”

“If we find this special electromagnetic signal in the corresponding records, it would partly validate this hypothesis.”

“If not discovered, then of course the hypothesis would be incorrect.”
