Chapter 903 Two hundred megabytes

After a main-sequence star that is near the end of its life becomes a red giant, its temperature will rise sharply and its volume will expand rapidly.It will soon expand its diameter by two hundred times, devouring the planet whose orbit is close to itself.

It's just that this "soon" is measured by the universe as the standard.

In humans, this process would take quite a long time.

However, the sun does not need to expand so much to destroy human beings.Just a little bit of heating or cooling of the sun would be catastrophic 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 star." Xiang Shan put his hands on his chest, closed his eyes, and asked: "Then, I will give you permission to make any plans you can think of. , what will you do?"

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

"Humanity's current technology is simply impossible to complete interstellar migration. This is something we have just discussed." Xiang Shan closed his eyes and said, "Directly take a spaceship to emigrate? Impossible. Because there is no way to create such a large Enough to hold the spaceship of the immigrant group. Go to hibernation? It is even more impossible. The success rate of human hibernation technology is very pathetic."

"Taking a step back, 'frozen sperm and eggs' and 'parenting robots' are not unacceptable. Teams immigrated in the form of cells may no longer belong to humans in terms of social attributes, but under this premise, they are still 'Acceptable', right? At least they have continued the creature 'human'. Ah, but if there is any malfunction in the parenting system, even if these fertilized eggs become babies, they will all die young."

"But what if freezing cells doesn't work? Or, what if any organic matter can't support it?"

"For example, this journey takes 10 years, 100 million years, etc. 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 at all... Take another step back? One step?"

"'As long as the things that arrive in the new homeland include our genetic information'." Xiang Shan sighed: "Compared to the choice of 'not culturally human, but biologically human', it is actually just a step back. And at this time, if we take a step back, it is...'as long as we have the genetic information of our planet's organisms'."

"But Ogun has no cells in it!"

"Didn't you say it just now? Because no cells can last for 10 years, maybe letting cells multiply in Ogun is also an option-choose some cells that can absorb nuclear radiation and put 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 couldn’t keep it sealed for 10 years. The atmosphere and water inside have been lost.” Xiang Sandao: "Ogun's voyage time is too long. Such a long time, such a low level of technology, nothing can be guaranteed."

"As you said just now, the information engraved on the slate is still there, and the information outside the slate has disappeared in large numbers. The mechanical system is aging due to the accumulation of errors as a whole, and the possible microorganisms cannot keep up with the internal environment of Ogun. changed and became extinct. In the end, only the information on the slate was conveyed."

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

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

"correct."

"Two hundred trillion."

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

"But is that really enough?"

"This is [-] megabytes compressed by the compression algorithm." Xiang Shan said, "I remember that all the genetic information of human beings is only a few gigabytes?"

"Considering that there are a large number of repetitive sequences and conserved sequences in the genome..." Yawgmoth stroked his chin with his right hand, thinking: "Perhaps it is possible to develop a compression algorithm with a high compression rate?"

"There must be a way to record them in the simplest order, remove all direction symbols, start symbols, and stop symbols, and convert them into binary or quaternary. By reproducing organic matter, it may be possible to create..."

Xiang Shan rubbed his forehead, thought for a while, 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 the recreated cells to become intelligent life again. During this process, the original genetic information has long since been mutated beyond recognition Right? No, the emergence of intelligent creatures is an accidental event! Perhaps the sun in the new homeland has also become a red giant, and the cells that are produced are still plankton, and there is no sign of evolution at all..."

"But the genetic information carried by those plankton has existed for billions of years." Xiang Shan said: "They can only send [-] megabytes of information with all their efforts. 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', then it is for 'the continuation of genetic information'." Xiang Shan said, "I think it's back to basics."

Yawgmoth said suddenly: "If this information is carried by other civilizations, it may be a 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 unbelievable. Just for this bit of genetic information?"

"Think about it, your planet is about to be destroyed, but your civilization can only transmit [-] megabytes of information with all its strength." Xiang Shan sighed: "At any rate, some microscopic biological reactions are still based on the lowest energy. Principles and other physical laws are common to the entire universe. But culture... who knows if your culture is based on some unique physiological mechanism?"

"These [-] trillion are already a civilization, and it's the cry of the last strength."

"After all, they really only have a chance of [-] trillion."
