"If you only have a few more days to live in this world, how are you going to spend those few days?"

"I spend these days with my family because I am usually very busy at work and have no time to take care of them."

"I may confess to the girl I like that I have had a crush on her for many years and have never had the courage to say it to her."

"I will donate all my assets to charities to help those in need."

"I said upstairs, you're too fake, aren't you? There is no real name here, so what you say is so high-sounding as the spokesman of the Ministry of Foreign Affairs? ”

"9494, if I am dying, I must spend all my money before I die, eat, drink, have fun and sing all night, and also experience what it means to be drunk and drunk, otherwise I will not come to this world for nothing."

"Cut, the world is really going to be destroyed, no matter how much money there is, it's just waste paper, you can't spend it at all, it's better to master a few weapons to get affordable, see all the men killed, see all the women raped, by the way, grab the nuclear button suitcase of the leaders of various countries, try to see if it can really be launched, this is the last madness!"

"Look! This is the inferiority of human beings! Finally speaking your mind, right? It can be seen how obscene and dark you guys are in your usual sanctimonious manners! ”

"I accidentally took the moral high ground upstairs again, and I was addicted to pretending to be a, right? I don't believe you haven't thought that much in your heart, the keyboard man said beautifully, maybe when the aliens come, the first traitor to be a traitor is you, no, you are an earth traitor, a solar system traitor! ”

"Okay, don't argue, this topic is too heavy, and the landlord has a problem with this topic, and he didn't explain the cause and effect, whether he has cancer, AIDS and other incurable diseases and has no days to live, or the world is going to destroy human beings and the earth is going to explode, there is still an essential difference. If the latter is the case, IMHO, everyone knows that in a few days the end of the world, human society will inevitably fall into great chaos, think about it, human beings are going to be extinct, can law and morality still restrain the demons in everyone's heart? The arrival of the end will only make those people more bottomless and unscrupulous, and I guess even the police will not have the heart to arrest people at that time. As for the first case, are there still fewer people getting cancer and AIDS over the years? I don't seem to have heard of anyone who has a terminal illness and does everything to kill people and set fires, unless that person has rabies or is bitten like a zombie in a post-apocalyptic movie, but it is not his subjective consciousness that he will do bad things, because he is already delirious and can be treated as a severely mentally ill person. Besides, a terminal illness is not a death sentence, and isn't the original smallpox tuberculosis also a terminal disease? I have reliable internal sources that it is said that Fermi has already started to implement the 'crossing' plan, which will send people to the future by freezing them, when all incurable diseases such as AIDS, cancer and so on will be solved. ”

"Please, don't you watch the news?" The 'crossing' project is now a household name, okay, what kind of uncle party is still doing here, besides, do you really believe that a small third-rate company like Fermi, which is barely listed, has the strength to study a world subject that has been painstakingly worked hard by generations of top scientists without substantial progress? The crude technology hype is not just to sell a few more dollars for stocks, which is similar to Hawking's obsessive black hole all day long and finally just to sell a few more books. ”

"Looks like we're going to have to sort things out for you stupid humans, so sit down and applaud. First of all, it's a foregone conclusion that Stephen Hawking is a true theoretical physicist, not a best-selling author of children's fiction as you would call him, right? Needless to say, although Hawking does seem to have strayed in some branches of research. Second, Fermi is not a small company, but a little-known strength group, they have several of the world's top basic physicists in their laboratory, and there are many projects with the Chinese Academy of Sciences. ”

"Speaking of the 'crossing' plan, I have to complain here, such a lofty future science and technology project, but the name is too earthy and too low, which reminds me of the inferior Xiaobaiwen on the Internet that I read in elementary school, which caused physical discomfort. Well, speaking of which, I have to brutally pop the beautiful soap bubble of your dreams once again,' The crossing plan is actually two projects, but the principle of operation is similar, that is, freezing, one of the items is room temperature freezing, this method requires the injection of a viscous reagent in the human blood, to minimize blood circulation and metabolism, the freezing temperature range, but also due to each person's physique is different, generally between minus ten degrees Celsius and minus dozens of degrees, figuratively speaking, in fact, it is to let a vegetative person hibernate, the difficulty of the operation lies in the precise control of temperature, under the premise that the cells are not frozen to death as much as possible to reduce the temperature and maintain cell activity, it is said that they have developed the first generation of reagents and experimented with mice and monkeysThe results of the experiment will not be known until two years later. This is somewhat similar to the hibernation plan described in "The Three-Body Problem", which does not use the extracorporeal circulation system, but in fact it can only be done for a short period of time. The longest is only a few decades, because the organs are still aging, although this process has been slowed down dozens of times, but if you insist on asking to be frozen for hundreds of thousands of years, then you may miss your life, or even die directly, I do not recommend that most of the people in the countries and regions that have not passed the bill use this project as a substitute for euthanasia, because the cost of these reagents and freezing is not cheap, much higher than jumping off a building and jumping into the sea and touching the electric door. ”

"Another project is ultra-low temperature freezing, how low is it? minus 273.15 degrees Celsius, that is, absolute zero in the standard sense, as everyone knows, under absolute zero, molecules are inactive, so cells can not talk about aging and division, theoretically can be frozen indefinitely, but absolute zero also only exists in theory, in fact, it is impossible to create a space that is completely free of molecular particle activity, there is no such space in the universe, it can only be infinitely close to absolute zero, and to achieve close to absolute zero, and to maintain it for hundreds of thousands of years, in addition to having an absolutely airtight rigid container, a large amount of liquid helium cooling is also neededand a continuous and sustainable supply of high-quality and stable energy. This energy source is, of course, electricity, even if it is necessary to maintain a small freezer close to absolute zero for one minute of electricity consumption is already an astonishing astronomical amount, not to mention to maintain this temperature for hundreds of thousands of years, before the realization of controlled nuclear fusion, there is no need to think about it, the manufacture of rigid containers is also a long way to go in terms of materials and processes, and there is a higher mountain to cross, that is, thawing, the human body frozen at absolute zero needs to be thawed to room temperature instantly, Otherwise, if the thaw is slow, the particles that make up the human body may be reorganized, turning into air or a pile of Tetris or a puddle of shit, or decomposing into a formless, colorless and meaningless pile of particles, and thawing the human body directly from a state close to absolute zero to room temperature is tantamount to a fool's dream for the current level of science and technology, so this second absolute zero freezing crossing plan is not reliable at all. Perhaps the only point is that physicists in certain countries can once again use the pretext of achieving controlled nuclear fusion to cheat some money. ”

"However, even if the above two methods can achieve hibernation and crossing, it will not have a half-curative effect on terminally ill patients, because the molecular structure has not changed, cancer cells are still cancer cells, HIV is still HIV, even if you freeze for thousands of years, and then come back to the world, idiots are still idiots, they will not become smarter, and lazy people will not become diligent because of this. However, if you really travel to a thousand years later, maybe people have completely cured cancer and AIDS at that time, and even found a way to live forever, but it is definitely better to build a time machine by yourself by relying on frozen travel, I am afraid that after a thousand years of human beings have long been extinct, you are left on the earth, lonely, miserable, and devastated, and then you should hate yourself for living too long and are anxious to commit suicide. ”

"Okay, I'm the landlord, don't be crooked anymore, there are many political and sensitive words in this post, I'll close the post now, let's all disperse, go back to each house and find each mother."

"The Last Days of Your Life", this is a post that Lifus accidentally found when visiting a Chinese forum before, published more than 500 years ago, when Fermi was only established, gravitons have not yet been discovered, Zou Dufeng has not yet become famous in the world, human beings have not yet gone out of the earth, people still have work to do, there are still marriage and family, nation and country, religion and faith, there are still bright days of spring birds and flowers, medical insurance and social security have not yet been popularized to everyone, poverty and hunger have not been eliminated, Cancer and AIDS were still being treated with conservative drugs and radiotherapy, and the average life expectancy was only a pitiful 70 years, when there were many kinds of animals and plants on the earth, and the sky was still blue.

"If you only have a few more days to live in this world, how are you going to spend those few days?"

Lifus is also thinking about this now. He searched carefully along the bottom of the cavity of the mountain, and found that there was no exit at all, and the results of the ray detection made him very frustrated, the rock walls around and under his feet were very thick, and the thinnest place was dozens of meters, but outside was a cliff and an abyss, and he couldn't detect it to the end, and he didn't know how deep it was. His current situation is like an ant falling into a Coke bottle, with no hope of getting out alive.

Since it is autumn and the flood season has passed, the underground river at the bottom of the cave looks more like a babbling stream, flowing from the southwest, dividing the bottom of the cave into two irregular areas, and finally flowing out from a stone crevice on the south side of the cave.

Lifus carefully observed and probed the crack in the rock, and it was possible to drill down with the radiation suit and equipment removed, and the river did not shrink at a distance of tens of meters, and there were no obstacles to block it.

But he didn't try it easily, the unknown river channel that can't be detected by the ray is undoubtedly full of danger, most of the channels that water can pass through can't be passed by the human body, and the water may even seep directly from the sandstone layer somewhere, so people can only wait for death, or the most aggrieved way to die. Livers decided to try again when he was finally cornered.
