First of all, according to the 7 levels of cosmic civilization.
The first-level cosmic civilization is also called "planetary civilization", the civilization has the ability to exploit and use almost all the energy and energy on the planet, that is, the civilization is the absolute "master" of the planet, can control the weather, land, various natural phenomena on the planet at will, know the structural changes and rises and falls of the planet above and below ground, and even have the ability to destroy the surrounding planets.
The second-level cosmic civilization, also known as the "stellar civilization", has reached the point where it can leave its planet at will to develop and harness the stellar energy near its planet.
The third-level cosmic civilization is also known as the "galactic civilization", which can easily control the galaxy in which it is located, and can also develop and utilize all the energy in the galaxy at will, and even draw the energy needed by its own civilization from the existing black hole in the universe.
The fourth-level cosmic civilization is the "cosmic civilization", because the civilization can already reach the development and utilization of 70-80% of the energy in the universe, and even the energy of the entire universe.
The fifth-level cosmic civilization has reached the point where it can easily integrate and utilize the energy in the multiverse on the basis of the fourth-level cosmic civilization...
The sixth-level cosmic civilization can be said to be the category of the "realm of the gods" currently being explored by human beings, which can control time and space at will, and can create different universes at will...
The seventh-level cosmic civilization is actually a reserved level, a level that we are completely unaware of.
The main story of "Doraemon" is based on the time travel of the "time machine". The sixth-level cosmic civilization is mainly in controlling time and space. Time is running out, and the space has "if the phone booth", "the world in the mirror" and "the opposite star".
The main body of "Rick and Morty" is a parallel universe, and the main benchmark is based on the fifth-level cosmic civilization, which can easily integrate and utilize the energy in the multiverse. On the topic of time, only one episode deals with the time rift.
But in Rick and Morty and Doraemon, they have actually reached the level of civilization that can create the universe.
In Rick and Morty, the ship's engine is a universe created by Rick to provide them with energy.
In the theatrical version of Doraemon, Nobita's Creation Diary is Nobita's summer vacation assignment that creates an observation of the universe.
If you look at it this way, the cosmic civilizations of the two worlds have already reached the sixth level of cosmic civilization.
The representative of the technological level of the Rick Universe is Rick.
In the Doraemon universe, Doraemon, which has a large number of unimaginable technologies, is just a defective parenting robot.
Guess which universe level is high?
The Rick universe belongs to Rick alone to forcibly pull up the high level, if you let the Ricks continue to study for more than ten years, catch up with the doraemon universe technology level, it should not be a big problem.
In the impression, there are probably several kinds of technology in the Rick Universe:
Space Teleporter (similar to an unlimited arbitrary door).
Robots for stand-ins (similar in Doraemon).
Laser weapons (Doraemon's air cannon, shock gun).
Spaceships (similar props are available in Doraemon).
Props that turn Rick into cucumbers.
Doraemon's props are more.
Typical representative: Ruyi phone booth. The setting is a prop that can create the universe and subvert the concept.
Well, let's just come here and say that I still want to hear your opinion!
