Chapter 903 Two Hundred Trillion

After a main sequence star that is reaching the end of its life becomes a red giant, its temperature will rise sharply and its volume will expand rapidly. It will soon expand two hundred times in diameter and devour planets orbiting closer to itself.

However, this "soon" is measured by the universe.

In humans, this process will last for a long time.

However, for the sun to destroy humans, it does not need to expand that much. If the sun gets hotter or cooler just a little bit, it will be a disaster for the Earth's biosphere.

Once this sign appears, humans may not have much time to prepare. Reduced food production and climate imbalance are enough to trigger a sharp decline in human populations.

"Suppose, just today, you observe the signs of the sun turning into a red giant." Xiang Shan clasped his hands on his chest, closed his eyes, and asked: "Then, I will give you permission to propose any plan you can think of. , what will you do?”

David and Yawgmoth looked at each other: "This..."

"It is simply impossible for mankind to complete interstellar immigration with the current technology. This is something we have just discussed." Xiang Shan closed his eyes and said: "Immigrate directly by spaceship? Impossible. Because there is no way to build such a large A spaceship that can accommodate an immigrant group? It’s even more impossible. The success rate of human hibernation technology is very sad.”

"To take a step back, 'frozen sperm and eggs' and 'nursing robots' are not unacceptable. The team that immigrated in the form of cells may no longer belong to human beings in terms of social attributes, but under this premise, they are still 'Acceptable', right? At least they have continued the 'human' species. But if there is any failure in the parenting system, even if these fertilized eggs become babies, they will all die."

"But what if frozen cells can't do it? Or what if no organic matter can support it?"

"For example, this journey takes a hundred thousand years or a million years. In such a long time, the corpses of living things are enough to become fossils. Things as complex as cells probably cannot be frozen for such a long time. "

"At this time, can we take a step back?"

David was stunned: "There is no organic matter in Ogun... One step further? One step?"

"'As long as the things arriving in the new home include our genetic information'." Xiang Shan sighed: "Compared with the option of 'not culturally human, but biologically human', it is actually just a step back. But at this time, if we take a step back, it would be... 'As long as there is genetic information from the creatures on our planet'."

"But there are no cells in Ogun!"

"Didn't I just say that? Because no cells can be preserved for a hundred thousand years, perhaps allowing cells to reproduce in Ogun is also an option - select some cells that can absorb nuclear radiation and place them in a corner of Ogun , Let them reproduce from generation to generation, but maybe those cells died before we humans discovered Ogun, because Ogun could not keep the atmosphere and moisture inside for a hundred thousand years." Sandow: "Ogun's voyage took too long. With such a long time and such low technical level, nothing can be guaranteed."

"As you just said, the information engraved on the stone tablet is still there, but the information outside the stone tablet has disappeared in large numbers. The mechanical system has aged due to the accumulation of overall errors, and the possible microorganisms cannot keep up with the internal environment of Ogun. changes and became extinct. In the end, only the message on the stone tablet was conveyed.”

Xiang Shan sighed: "So, the truth about the codebook may be this. It is part of the genetic information of aliens."

David was stunned: "But, it's only...two hundred megabytes?"

"yes."

"Two hundred trillion."

"Yes." Xiang Shan sighed: "They tried their best, but they could only send 200 megabytes of information."

"But is this really enough?"

"This is 200 megabytes after being compressed by the compression algorithm." Xiang Shan said: "I remember that the entire genetic information of human beings is only a few gigabytes?"

"Considering that there are a large number of repeated sequences and conserved sequences in the genome..." Yawgmoth rubbed his chin with his right hand and thought: "Perhaps a compression algorithm with a high compression rate can be developed?"

"There must be a way to record it in the simplest order, remove all direction symbols, start symbols, end symbols, etc., convert it into binary or quaternary, and use the simple ones that are available locally at the destination. By reproducing organic matter, perhaps we can create..."

Xiang Shan rubbed his forehead, thought for a moment, and said, "Create alien creatures with the genetic information of their planet's creatures. The rest can be left to time."

David shouted: "But does this make sense? It may take billions of years for these re-created cells to become intelligent life again. During this process, the original genetic information has long been changed beyond recognition due to mutations. Right? No, the emergence of intelligent creatures is an accidental event! Maybe the sun in the new home has also become a red giant, and the cells that were created are still plankton, with no signs of evolution at all..."

"But the genetic information carried by those plankton has existed for billions of years." Xiang Shan said: "They tried their best and could only send 200 megabytes of information. This is the best result they can achieve."

David shook his head: "I still don't understand. Without human civilization, there is nothing special about human genetic information."

"If life has a 'purpose', it is for the 'continuation of genetic information'." Xiangshan said: "I think it is very simple and natural."

Yawgmoth suddenly said: "If this information is taken by other civilizations, it may also be a kind of continuation. At least the fire created by their planet for billions of years can be passed on to other civilizations."

David shook his head: "This... is too incredible. Just for this little genetic information?"

"Think about it, your planet is about to be destroyed, but your civilization can only pass on 200 trillion information with all its strength." Xiangshan sighed: "At least some biological reactions at the microscopic level are still based on physical laws such as the principle of minimum energy, which are common to the entire universe. But culture... Who knows if your culture is based on some unique physiological mechanism?"

"These 200 trillion are already a cry of a civilization, using all its strength."

"After all, they really only have 200 trillion chances."
