Today, Amway is a relatively niche, but many people call it a god-made anime - "Destiny Stone Gate".
The setting in this anime is not very kind to the audience, quoting various theories that do exist in reality, and students who are drilling the horns need to consult some information if they want to fully understand.
Even so, it can still win a good reputation with an excellent plot, theoretical loopholes aside, logic is basically impeccable, which is very rare for science fiction themes.
Introduction: Ryutaro Okabe – a college student with secondary two diseases, who calls himself a mad scientist - Phoenix Temple. He invented the "Telephone Oven (Tentative)" in the Institute of Future Machinery, a prop with an amazing function similar to time travel, capable of sending e-mails to the past. One day, the protagonist meets an 18-year-old genius girl, Makise Hongliqi, but only a few hours ago, the protagonist witnesses her being killed on the roof of the building... The story unfolds.
Simple spit on the theoretical part of the anime (if there is any omission, welcome to correct)
1. About time travel
Space strings:
It has a super massive mass, shaped like a string "crack", the width of the crack is about the same as that of elementary particles, and the shortest length must be the same as that of the Milky Way. Because it has a huge mass, it has the property of being able to distort space-time, and rotating the distorted space-time around you in the center of the string can go to any angle within 360 degrees.
That is to say, it is possible to do the same action as time and space jump, which is called the loss of angles in space-time...
what the hell？ Anyway, just accept it as a conclusion, right?
Wormholes:
Throw one end of the wormhole to the end of the universe at nearly the speed of light, and then immediately pull it back, according to the theory of relativity, moving at the speed of light time will slow down, in this case jumping into the wormhole can go back to the past, but the other end of the wormhole is often another location, so you have to do this step again to go back to the past of the current location...
Throughout the explanation, I seem to know only the "theory of relativity"...
2. Use Kerr black hole theory for data compression
According to Einstein's equation for gravitational field, the gravitational field of a rotating star that shrinks into a black hole eventually reaches a state of equilibrium that depends on only two parameters, mass and angular momentum, which represents the rotation speed of the star, similar to the spin of elementary particles.
Today's simulation diagram shows that Kerr's black hole is first of all axisymmetric, that is, the energy of the test particles rotating around the axis of symmetry and moving as short-range lines is conserved; at the same time, its angular momentum components around the axis of symmetry are also conserved; in addition, it also allows the test particles to follow the third conservation law; and in Kerr black holes, all mathematical equations, including some equations that govern the propagation of gravitational waves, can separate variables and thus obtain a clear solution.
I don't know if it is because of this reason that pig's feet can compress more than 3 terabytes of data into 36 characters, anyway, I really don't understand ~
3. The theory of animation (game) creation
World line convergence theory - wait, parallel worlds and this kind of I understand, different choices will cause the world to develop in different directions I can also understand, but there is only one world, the universe is only one, the reason why there are two world lines, is because of the existence of [observers], and small world changes will only be (cosmic force?). Gradually converging on the same world line...
exuse me？
The concept of the observer – the ability to reconstruct the world and retain memories.
Simply put, what does it mean from God's perspective?
4. Everything is the choice of the Stone Gate of Destiny
The Gate of the Stone of Destiny – The only world line that is not affected by the confines of the world line
Trick the observer, deceive the original self, deceive the world to get the happy ending?
Even if you know the method, you must not change the past, you must not transform the possibilities of existence into an established reality, the future is unpredictable, it is impossible to repeat, which is why people can accept all kinds of pain, misfortune and flying disasters, and stride forward - the phoenix courtyard is fierce
Finally, because the story is set in such a large way that students who want to fully understand Destiny Stone Gate can complete its games and radio dramas.
