Chapter 21 Tritium Tube
What is half-life?
Half-Life is a game developed by a fat guy with a binary brain Phew.
The half-life is the time required for half of the atomic nuclei of a radioactive element to decay. Determining historical dates based on the half-life of the radioactive isotope carbon 14 is a commonly used research technique in archaeology. As long as the decay content of the radioactive element is measured, the age of the target object can be determined.
It sounds quite high-end, and seems to have nothing to do with ordinary people's daily life, and even less to Bai Yang, an ordinary high school student. We ordinary people live peacefully, what does it have to do with radioactive isotopes? What does it have to do with half-life?
Yes, please raise your left hand.
Roll up your sleeves.
Look at your watch dial in the dark - if you are an old-school...gentleman with a vintage luminous watch, its dial is coated with a common radioactive isotope.
tritium.
Bai Yang didn't even bother to sleep. He immediately got up from the bed, took out his cell phone and opened Taobao.
With the help of the almighty Taobao, there is nothing you can't buy.
Tritium tube!
Tritium tube is a common luminous tube, fully enclosed glass material, small ones are a few millimeters long, large ones are one or two centimeters. The inner wall of the glass tube is coated with phosphorus fluorescent powder, while the tube is filled with tritium, a radioactive isotope of hydrogen. The thin tritium gas is weakly radioactive, which excites the fluorescent powder to glow. This thing is often used in luminous watches, military compasses, and rear sights of firearms. Sometimes it is also used as a buoy indicator light by anglers who never go air force.
The half-life of tritium is twelve years, which means that half of the tritium elements will die after twelve years, the brightness of a tritium tube will drop by half after twelve years, and it will be close to extinction after twenty years.
The timing is just right!
Tritium tubes are just right for use as time calibration objects.
Bai Yang planned to buy two brand new tritium tubes on Taobao, and then go to Xianyu to find a tritium tube that had been used for about five years and another that had been used for about ten years, two new and two old.
This is his plan:
Use UV glue to stick the four tritium tubes in a transparent plastic box and arrange them in the order of new, five years, ten years, and new. When BG4MSR digs out the time capsule, Bai Yang will ask her to find the time marker inside the capsule and ask her to answer about the luminescence of the tritium tubes. If the four tritium tubes are luminous normally, and there is no difference from when she buried them, then the other party is talking nonsense.
Doomsday and 2040 are all bullshit.
If the four tritium tubes emit almost no light in the dark, it proves that the girl is telling the truth and at least twenty years have passed.
If the five- or ten-year-old tritium tubes were extinguished but the new ones were still glowing, that would prove that BG4MSR was indeed living in the future, but she had misjudged her own age.
Bai Yang believes that there is no harder and more tenable evidence than this. This is what is called using force to overcome cleverness, grasping the essence, and going straight to the main point, without so many twists and turns. Even if the opponent is James Bond, 007, or the flying thief, and there are ten thousand ways to secretly dig out the time capsule underground to see what is hidden inside and then bury it back as it is without anyone noticing, it cannot change the luminescence result of the tritium tube.
As long as you don't reveal in advance that it is a time marker or a tritium tube, the other party will not be able to know what it is, let alone lie to you.
By verifying with forces beyond human reach, all falsehood and lies can be eliminated.
This is Bai Yang’s method.
I buried the tritium tube here, come on!
I am not afraid of any means you use, no matter how you do it, as long as you open the lid and take a look, I will definitely know whether what you say is true or false.
Place your order!
Thirty yuan each, and two cost sixty yuan.
It's going to hurt for a while again.
But Bai Yang was eager to try. As a high school student who had studied hard since childhood, he rarely had the opportunity to do such a bold, absurd and rebellious thing. However, Bai Yang became more and more excited. His dull life, which was as boring as boiled water, finally had a hint of different color. In novels and movies, this is often the opening of a grand adventure. He did not fall asleep until three in the morning, his mind full of his plans, and he overslept the next morning.

Banxia put down her headphones and microphone and slowly lay down on the desk.
What does he mean?
Can you provide me with evidence? Can you prove that this year is 2040?
But doesn’t he claim to be living in 2019?
How can a person who lived twenty years ago help me?
The girl's cheek was pressed against the cold wooden table, her right elbow resting on the table, and an amulet was hanging on her index finger, gently swaying like a pendulum - it was a coin left for her by her teacher. There was a hole in the coin and a red string was passed through it, so she could usually hang it around her neck. Banxia's eyes followed the coin as it swayed back and forth, and she was puzzled.
The fat plastic desk lamp was placed next to Banxia's head. It was the only light source in the room. The girl's face was illuminated by the light, while her body sat in the dark. She liked to sit in the dark and think. The quiet night could calm her brain enough.
How could he provide me with evidence over twenty years?
Bury it? Hide it? And wait twenty years?
Banxia easily thought of this. The other party lived twenty years ago - let's assume that he really lived twenty years ago (in fact, Banxia didn't believe it, but she had no choice), then he dug a hole in that era, buried the things he wanted to send in the soil, and then notified herself through the radio station and asked her to dig it out.
If you can find it, it proves that it is all true.
He will know that she lives in the year 2040.
She was also able to confirm that he lived in 2019.
Sounds wonderful.
Banxia stared at the red rope and coin hanging on her fingers. The coin gradually lost kinetic energy due to friction, and the amplitude of its swing became smaller and smaller. Finally, it stopped and slowly rotated around the hanging rope, twisting the rope into a double helix.
This sounds reasonable, but the teacher once said that what sounds like what looks like is different, and what looks like what is done is different. To judge whether something is feasible, it is not enough to rely on ears alone. You need to mobilize your ears, eyes, hands and brain.
The girl's brows slowly frowned, and she was vaguely worried.
If the other party really wants to do this - if he really wants to purposefully deliver something to you over a long period of twenty years, then this may not be an easy thing to do.
Once you have a goal, obstacles will naturally follow. This world always makes you arrive at a destination you don’t want to go to inadvertently, and at the same time sets up many obstacles in front of the destination you want to reach.
It is definitely - definitely - not as easy as it might seem.
