We all know what length, depth, width and time are. These measurements allow us to perceive the world as (as we think) it is. But in truth, we have been looking for other dimensions for a long time that may be hidden from us. We turn to the physics of cartoons and games, consider the ideas of an ever-expanding universe and, in the end, come up with completely amazing theories.
Super Sargasso Sea
In one of his books, the writer Charles Hoy Fort described the "super-Sargasso sea", a dimension that collects all the things that disappear in our world, and then vomits them back. The most obvious example of the existence of such a sea for him was the rain of animals. According to Fort, it is the "super-Sargasso sea" that gives birth to animal rains.
The "Super Sargasso Sea" revolves above and with our world (or remains stationary above us while we move). Fort even imagined that aviators could lead expeditions to the "super-Sargasso sea" and find there animals that have disappeared from Earth, or other things swallowed by the sea - even messages from other worlds.
Studying the places where the mysterious rains appear, the Fort came to the conclusion that its sea stretches from Great Britain to India. Search at your leisure.

Hammerspace (pocket universe)
In cartoons, we see this all the time: the character pulls something out of thin air and uses it to create a comic effect. This mysterious dimension, which stores random things, has a name: pocket universe, hammerspace.
Invented by fans of the anime Ranma ½, pocket universe refers to a place that exists outside of the camera. Clowns know the most about this space. Perhaps this is the habitat of clowns. Often, cartoon characters get hammers and other weapons from Hammerspace, with which they beat each other to defuse the situation.
The pocket universe has different sizes: in one you can store several things, in the other you can open a door and exit on the other side of the globe.
Paraspace
Paraspace was invented by writer Samuel Delaney to describe a common feature in science fiction: when a character leaves his own world and travels to another place, those places exist in paraspace.
What happens in para-space affects the real world of the character, and before the appearance of this term, other dimensions were called subspace. Delaney decided to move away from him, emphasizing that another dimension is no less real than the one in which the character was born.
After this idea was extended to such things as experience or the feeling of the otherworldly, when the experienced sensations are so strange and bizarre that a person begins to see them more clearly than his real environment. In general, this is a dimension within a dimension when there is no "in between". It's hard to imagine, I understand.
Flatland
In 1884, a minister and scientist named Edwin Abbott Abbott wrote a book in which he presented a world with only two dimensions. "Flatland" is the story of a character, a modest square who lives in a world in which the more edges and corners you have, the higher you stand on the social ladder.
Once every thousand years, Flatland takes on a being from another dimension - three-dimensional. This being, a three-dimensional sphere, is trying to convince those living in Flatland that there is a whole other world. Abbott describes a flat world in amazing detail, from how the cardinal directions without a sun or stars are determined, to the laws of inheritance and the role of women in the society of this world. The result is a satirical picture of Britain in the Victorian era.
Funnel of time
Doctor Who travels a lot in time, back and forth, in space and space-time, all using the TARDIS. More recently, several real scientists have outlined the possible principles of the TARDIS and described how this setup enables time travel.
The TARDIS (which by its nature is larger on the inside than on the outside) is a bubble separated from the outside world by a curve of space-time. Anyone on the outside will see two bubbles that first separate and then merge when the person inside moves in the same direction. This is because they begin to move in a circular trajectory (similar to the movement of objects in the night sky) and for the same reason we see that the planets change direction in retrograde motion.
Although this works in theory, in practice it is unlikely, since the substance necessary to start the process will openly violate the laws of conservation and consumption of energy.
L-space
According to Terry Pratchett, this logical ideal equation describes the relationship between knowledge and power: books = knowledge = power = (strength x distance2) / time. And this is where the L-space comes in.
L-space is the dimension that connects all libraries. And you can be in them without even realizing it. Large libraries can become an L-space full of shelves of books that stretch indefinitely. This dimension contains every book written in the world, every book yet to be written, and books that were in plans but were not written.
Anyone who learns to cross L-space can find and read any of these books, but they will have to follow strict rules. Only senior librarians are privy to the rules (keep quiet, return books on time, don't break causation) and know how to avoid potentially dangerous books.
Hyperspace
Hyperspace is a famous science fiction cliche where energy from other dimensions creates a spatial back door for travel faster than the speed of light. The methods for such travel are very different; today we are used to "using" wormholes for this, hundreds of years ago we used something completely different.
The idea of fast travel through space goes back to 1634 and the book Somnium by Johannes Kepler. In it, people travel to an island 80,000 kilometers above the earth, and the only way to get there is to open an interdimensional path with the help of demons. Kepler described that demons begin their journey depending on the phases of the moon. With the help of opium, they put travelers to sleep and use an unknown force of acceleration to move them through space.
5-dimensional black holes
In 2002, theoretical physicists developed the idea of ring-shaped black holes, but only 14 years later supercomputers were able to model them. This theory describes a black hole that somehow forms a series of bulges that are cut off to create new black holes, much like water dripping from a tap. In the process, a pure singularity is formed, and the theory of relativity - the basis of all our scientific theories - collapses.
A black hole of this kind can only exist in five dimensions, and only in five dimensions can a pure singularity form on our side of the event horizon. General relativity suggests that these singularities are born only when they are safely trapped inside a black hole, but ring-shaped black holes, in theory, can lead to the creation of a naked singularity and violate the laws of the universe.
Pockets of the universe
Alan Guth, a theoretical physicist at the Massachusetts Institute of Technology, is believed to be the originator of the idea of cosmic inflation. Part of this theory is that the universe is constantly expanding, and as it expands, it creates more and more space-time. Together with it, an infinite number of pocket universes are born, such portions of reality in which anything can happen and will happen through an infinite number of time.
Guth believes that we are in one of these pockets, with an infinite number of other pockets around us. The "pockets of the universe" are the plural of the universe, and in each of these pockets the laws and constants of nature remain homogeneous. Leave the pocket of the universe - and everything will change, from physical laws to measurements.
The theory of ten dimensions
Most of us perceive the physical world in three dimensions - length, depth and width. To these three spatial dimensions is added a fourth, temporarily, dimension. However, according to superstring theory, we are somehow influenced by several other dimensions, although we do not perceive or see them.
The fifth dimension exists with our world and is simply different from ours enough for us to measure this difference. The sixth is the plane on which all possible universes and pockets of the universe exist, but only those that were born like our universe. The seventh dimension consists of worlds that began with conditions different from ours, and the eighth dimension is a dimension of the endless stories of the worlds of the seventh dimension.
In the ninth dimension, there are worlds with physical laws that differ from ours. The tenth dimension contains everything we can imagine, and much more. Since it contains more than we can imagine, according to this theory, we cannot imagine or understand more than ten dimensions.
