World line: Stone Gate is set as a single universe (there is no parallel universe), the single universe runs according to the world line, but changes in the past will cause the world line to change (that is, the node where the universe was changed in the past, runs according to another line).
World line convergence: If the past change is an ordinary event, the changed world line tends to converge, which will lead to a fixed result. The α world line (Greek letter + world line) is a collective name for many world lines that are converged.
The world line beats: If the past changes are major historical events, the world line beats, and the future will also undergo great changes.
Normal beta line (without brooch intervention): John Tito appeared in 2000, published the world line theory → the assistant completed the time machine paper based on John's theory → the assistant and the father held a time travel conference in Japan on July 28, 2010 → the father Kill the assistant and snatch the paper→The father escaped to Russia to publish the paper→The time machine caused the third world war→The research on the brooch and the barrel was successful. The full version of the time machine (can travel through the past and the future)→The working soldier returned to 2000 in the time machine Annual pseudonym John Tito
Normal alpha line (no brooch intervention): The working warrior appeared on July 28, 2010. Due to the coordinate deviation, the time machine smashed on the roof of the conference building, and the meeting of the assistant's father was canceled → sern monitoring lab → sern shot and killed, I am happy, take the assistant away Develop a time machine, the assistant becomes the mother of the time machine, and the future becomes the town of despair → Brooches and barrels escaped to form a resistance organization, and the barrel developed a time machine with residual blood (can only go back to the past, not the future) → The working warriors come year 2010
SG line was deceived brooch observation perspective: brooch witnessed the death of assistant (actually not dead) → sent the first Dmai, causing sern monitoring → world line became α → sern shot and killed, really happy to capture assistant → brooch is really happy to save, more Time travel, change the world line → the brooch removes sern's monitoring of the first Dmail → the world line changes back to SG, the assistant is still alive at this time
Main line (until episode 24): The β-line brooch witnessed the killing of the assistant, and sent the first Dmai → Since this Dmai was monitored by sern, major historical nodes changed, and the world line was changed from β to α → α World line under the brooch to save Really happy, traveled through time many times and changed the world line → Finally, the brooch found that the reason for the change of the world line was the first Dmai, so sern's monitoring of the first Dmai was eliminated → the world line changed back to β (the assistant was dead at this time) → brooch Deceiving yourself in the past, because the assistant did not die and the assistant's father's paper was burned, the major historical node changed → the world line became SG
The difference between alpha line and beta line:
1. The future of the beta line is the third world war, and Brooches and Buckets have developed a complete version of the time machine; the future of the alpha line is the desperate township ruled by sern, and the bucket has developed a remnant blood version of the time machine.
2. The α-line working soldiers have not been to the year 2000 due to the residual blood of the time machine.
3. Since the alpha-line John Tito did not appear, the alpha-line assistant did not believe in the time machine theory, while the beta-line assistant perfected the thesis based on John's world-line theory. (Therefore, it is impossible for the assistant on line α to die on July 28, 2010. Even if the meeting is held normally, the assistant's father will not kill the assistant for robbing papers.)
The difference between the beta line and the SG line: 1. The SG line assistant is not dead. 2. The papers robbed by the SG line assistant's father were burned.
Many Dmails in the alpha line do not need to be cancelled (such as buying lottery tickets, multiple Dmail experiments when the assistant summarizes the rules, etc.), because the changes in the world line caused by these are too small, it is impossible to cancel them back to the beta line. There is no need to cancel the Dmail of Suhuazi et al. In theory, Suhuazi can be kept jumping back to the beta line for women.
