My biological black technology

"DNA hard drive?" Hou Zhijie took a deep breath after hearing this, "Using base pairs to encode data, similar experiments have indeed been verified in current academic laboratories."

"And in terms of storage density, DNA hard drives are a hot topic for mass data storage in the future. Theoretically, one kilogram of DNA hard drives can store all the information in the world. However, this technology still has too many difficulties to overcome. Problems such as slow synthesis speed, high synthesis cost, inability to read and write quickly, and inability to read and write randomly.”

"However, being able to artificially synthesize DNA weighing ten kilograms and still preserve it for such a long time is enough to judge that the alien intelligent creatures that made this box are technologically more advanced than us and can create a practical DNA hard drive. The possibility is very high." Hou Zhijie followed Cheng Xiang's thinking and said, "If this is the case, then a 200g DNA hard drive in a single small box should be able to store 400 million TB of information."

"If the content inside can be parsed out! Even if there is only one thousandth or one ten thousandth of the useful information, it will bring immeasurable value." Hou Zhijie's breath tightened when he said this, and his breath became very Urgent.

Cheng Xiang's expression also became solemn at the same time.

Indeed, as Hou Zhijie said, if this is really a hard drive, a DNA data hard drive left by an alien intelligent creature, then its value is absolutely inestimable.

The data volume of 400 million terabytes is enough to store one-fifth of all the information currently held by humans on earth. Such a massive amount of information, even if it is partially complete and partially useful, is still a huge golden mountain waiting to be mined.

In particular, this is the information left by an alien intelligent civilization.

No one knows what would be stored on such a data hard drive.

The information stored here may be the wisdom and social sciences of other civilizations, it may include more advanced civilizations’ understanding of the universe, it may be their own research, and it may also include their scientific and technological achievements.

There is so much space to imagine.

Between two civilizations with vastly different technological levels, even a common toy in the eyes of a high-level civilization is full of value for learning and research in the eyes of a low-level civilization.

Silence for a few seconds.

Cheng Xiang and Hou Zhijie looked at each other and felt deeply the huge possibilities and endless imagination. Maybe there was important information to solve the gene lock problem.

After dozens of breaths, the two tried to calm down.

"We have to adjust the research plan."

"The research team can be divided into two parts. One part will follow the previous ideas and study the genetic characteristics in a biological direction to find out whether there are gene fragments that match biological characteristics. The other group can assume that these DNAs are storage media, and then use biological storage The idea of ​​​​the medium to find its laws."

"It should indeed be like this." Hou Zhijie agreed, "I will make arrangements right away."

Soon, the previously transferred research team immediately divided new tasks under Hou Zhijie's arrangement. At the same time, Hou Zhijie made a brief report to his superior organization. In addition, through this secret channel, he applied for more than a dozen urgent tasks. Information storage experts came to assist.

With this important new discovery about the mysterious box, the possible huge value in it cannot be overemphasized, so that night, eight information storage experts were in place, and the rest were on their way. On the road.

In the blink of an eye, four days passed.

The newly received data today has been sent to the space center.

Cheng Xiang skillfully copied the project files from the hard disk to the computer and double-clicked to open them.

"If the genetic data in the last 10 numbered boxes are successfully compared with the gene sequences in the previous 39 boxes, then our previous guess that these 49 boxes store the same information should be able to be concluded. A definite conclusion." Cheng Xiang said.

Hou Zhijie, who was standing aside, nodded in agreement. At the same time, the information storage expert who was standing aside also nodded at the same time, "Yes, the data in the thirty-nine boxes in front of it, although there are many individual wear and tear, but overall, From the above, it should be confirmed that it is the same data."

"If the genes in the next 10 boxes can still match, then we can be absolutely sure that the 49 small boxes in this box store the same gene, and the 49 copies are backups of each other. This is also the storage data The most common data disaster recovery and fault-tolerance measures."

"This makes the previous speculation that this box is an information storage medium more likely!"

Research matters are not considered certain until they are fully verified and successfully verified.

This comparison work has been going on for five days, and Cheng Xiang is already very familiar with it. He summarizes and imports the newly obtained data documents into the local computer engineering library.

Select all numbered documents and start comparing!

With the help of supercomputer, the entire calculation process only takes more than ten seconds, and the results have been obtained.

Everyone looked at the calculated statistical results.

The result is exactly the same as the previous incremental comparisons.

After eliminating interfering factors, the same parts are five nines.

Joy flashed in everyone's eyes, Cheng Xiang took a deep breath and stood up. "So far, we can draw a definite conclusion. The genetic maps in these forty-nine small boxes are definitely the same."

Hou Zhijie also burst into joy upon hearing this.

"Furthermore, according to the research progress of another group of ours, no obvious biological genetic characteristics have been found yet."

"In other words, it is increasingly possible that this genetic map is a data storage medium."

Everyone around had no opinion on this conclusion.

Seeing that everyone had no different opinions, Cheng Xiang immediately continued: "In this case, we need to clarify our next work on this matter."

"Before we can do real data analysis, we must have good reasons to rule out that these genes record biological genes."

"Director Hou." Cheng Xiang looked at Hou Zhijie.

Hou Zhijie immediately stood up straight.

"I need you to evaluate the most appropriate sampling and testing plan in the shortest possible time. And notify the space center as soon as possible so that they can operate the scanning equipment on Mars according to our needs and extract the sampling data fragments we need."

"yes!"

"Remember, you must hurry up. In addition, I remember that in our current Mars space orbit, there are spacecrafts with the ability to return, and the Mars base also has the ability to send ground items into the Mars orbit. Please consult the space center immediately. If we need to get the box from Mars back to Earth as quickly as possible."

"With the fuel currently stored in the spacecraft staying in the Mars space orbit, how much time do we have at most. We must draw conclusions before that time period."

The shortest distance between Mars and the Earth is more than 50 million kilometers, and the longest distance is as long as 400 million kilometers. During this journey, the spacecraft needs to consume precious fuel whether it is changing orbit or accelerating. If there is not enough fuel, the only result is that the spacecraft will be lost forever, let alone the important things saved in the spacecraft. Therefore, this time must be determined from the beginning.
