What is the concept of multidimensional existence of time?

The idea of this parallel world is very similar to my thinking about "probability".

If "probability" really exists, that is, all kinds of possibilities are really possible, then it stands to reason that there will be parallel worlds.

If "probability" is just that people cannot predict the future, people's abilities are limited, and the future direction is the only certainty, then there is indeed no parallel world, but it falls into "fatalism".

At the level of energy we can grasp, time is a one-way dimension that cannot be retraced backwards along the timeline.

The level of energy at the disposal of our civilization is far from sufficient.

Under our current knowledge.

Time is a dimension that runs in one direction.

For this question, it is advisable to read a brief history of time in Hawking's book.

The one-dimensionality of time means that time has only one dimension.

Research: Starting from the analysis of the continuity and sequence of time and the relationship between the two, the characteristics of one-way one-dimensionality of time are demonstrated. A new field of interest in Chinese philosophical theory is the study of human subjectivity and human value.

The birth of Marxist historical materialism marks the scientific confirmation of the theoretical and scientific spirit of human subjectivity. However, for a period of time, China has been in an abnormal state of silence in the study of the main problem.

The concept of time in the history of philosophy arose from practice and developed with the development of practice and science. Generally speaking, the study of space began earlier than the study of time, and the results were more remarkable. When the ancient geometry and mechanics have made considerable achievements in the study of space, the study of time has hardly been involved.

Although we make extensive use of the concrete concept of space-visual metaphor for the concept of time, time is only one-dimensional compared to concrete objects that occupy a certain space with three-dimensional properties (length, width, height). Scholars have long discovered that many languages use one-dimensional (one-dimensional) spatial words to describe time. For example, we only say that time is "long", not "wide" or "high".

Time, in relation to space, is a continuous system of past, present, and future.

It's like it's four-dimensional. Because we can't see or touch, it's an abstract thing.

The point is one-dimensional, the line is two-dimensional, and the surface is three-dimensional.

Time is one-dimensional, space is three-dimensional, and space-time is four-dimensional, i.e., space + time.

Let's put it this way, the three-dimensional space plus one-dimensional time that Lao Ai said is actually four-dimensional space-time rather than four-dimensional space, and the two concepts are very different (a little bs old love, countless harms).

Of course, the fourth dimension of four-dimensional space will not be time, four-dimensional space plus time is called five-dimensional space-time, and the speed of time will not make us close to high-dimensional or low-dimensional space, if we are three-dimensional creatures, then I have always been and always will be three-dimensional creatures (different dimensions cannot coexist in the same space).

Because they cannot coexist, it is impossible for other four-dimensional beings to control our time, and the so-called compressed space is nothing more than the ability of the matter there to "perceive" several dimensions.

For example, a one-dimensional particle simply means that it will not move up and down, back and forth – that is, it has lost the ability to "perceive" the other two dimensions. In fact, it is still three-dimensional in our eyes.

LZ thinks a lot, do you study science?

In addition, I don't recommend Du Niang or anything.,If you want to go, go to the English Wikipedia .......

Let me tell you this: the two-dimensional space is a plane, the three-dimensional space is the space in which we live (it is three-dimensional), and the four-dimensional space is a virtual shadow, which people can see, but they can't be moldedDo you think they have something to do with the fast mantle of time loss?

Why is it that the faster we feel that time flies, the closer we get to four-dimensional space, and vice versa, the closer we get to two-dimensional space?

I can't understand this sentence, so I don't explain it, hehe, there are creatures in the four-dimensional space, this is not certain, but they absolutely cannot control time, this is for sure, you think about it carefully, we humans belong to three-dimensional creatures, right, but can we control three-dimensional? Of course not! Therefore, four-dimensional beings cannot control four-dimensional.

I don't know what the concept of four dimensions you understand?

Generally speaking, people recognize three-dimensional space, and time is called four-dimensional space-time.

The dimension of time is an abstract concept, embodied by the changes of space, and is not a physical existence.

One dimension is a line, two dimensions are a surface, three dimensions are static space, and four dimensions are dynamic space (because of time).

The parameters that we have to change in physics to describe a changing event. This parameter is called a dimension. A few parameters are just a few dimensions.

For example, to describe the position of a "door", only the angle is needed, so it is one-dimensional, not two-dimensional. To put it simply: 0 dimensions are points, without length, width, or height.

One dimension is a line made up of countless points, only length, no width or height. A two-dimensional is a surface made up of countless lines, with length, width, and height. A three-dimensional body is a body composed of countless faces, with length, width and height.

Dimension can be understood as direction. Because the human eye can only see three dimensions, it is difficult to interpret more than three dimensions. Just as a person with normal intelligence and a congenital absence of one eye and one ear (so that there is no binocular effect, binaural effect), it is difficult for him to understand distance, and he is likely to think that the world is two-dimensional.

To put it simply: n-dimension is the space formed by two perpendicular pairs of n straight lines. Because, humans can only understand 3 dimensions, so the later dimensions can be constructed by mathematical theories, but it is difficult to understand them carefully.

In quantum mechanics, the membrane theory, which is still being established, holds that the world is 11 dimensions. Four-dimensional space: The concept of space-time Most of the "four-dimensional space" mentioned in daily life refers to the concept of "four-dimensional space-time" mentioned by Albert Einstein in his "General Theory of Relativity" and "Special Theory of Relativity". Our universe is made up of time and space.

The relationship between time and space is that a time axis is added to the structure of space compared with the three axes of length, width and height of ordinary three-dimensional space, and this time axis is an axis of imaginary values. According to Albert Einstein's theory of relativity, the three-dimensional space we face in our lives plus time constitutes the so-called four-dimensional space.

In the very early days of the universe, within 10 -43 seconds of its birth, it was only 10 -33 centimeters in diameter, containing a wealth of ten-dimensional space, all of which were conjurified equally. In that space, the energy of the universe is extremely high, the temperature is extremely high, all four forces are integrated, and the theory of relativity and quantum theory can be reduced to one theory.

However, such a high-dimensional, high-energy, high-temperature space is extremely unstable, just like a balloon with too much flatulence, so the big ** happens. Dimensions are dissolved, energy diverges, and temperature decreases. Three-dimensional space and one-dimensional time extend infinitely, gradually forming the universe that we can perceive today; The other six dimensions are still confined to the Planck scale (i.e., 10 to 33 centimeters).

When the universe is at an extremely high temperature of 10 32 K (which is 10 26 times higher than the temperature of the sun that we get), gravity separates from other great unified forces, and gravity continues to extend as the universe expands. As the universe expands and cools further, the other three forces begin to break down, and the strong interacting forces and the weak-electric forces are stripped apart. <>

Is time multi-dimensional after all?

Whether time is multidimensional or not is a question that I would also like to know. Normally speaking, time is one-dimensional and linear.

Albert Einstein once made the point that the closer an object gets to the speed of light, the slower its time becomes. Assuming that a car is moving at 10 miles per hour, the light in front of the car is still moving forward at 10,000 miles per second, and if another car is traveling at 20 miles per hour, the light in front of it is still 10,000 miles per second. These two cars can't go faster than the speed of light, so their speed is distance divided by time.

Therefore, the reason why the light emitted by the car keeps the same speed is that the distance and time corresponding to the light change. So the faster the object, the slower its time will be.

There is also a time for light to propagate, because light is conducted to the eyes, and the eyes are reflected to the brain for time, so the world a person sees is always the world of the past. So the Sun you see is the Sun 8 minutes ago, and the stars and galaxies you see are all from N years ago.

Well, if a person has made faster-than-light motion with something, then what he sees is the past. The sun he sees may be the sun 9 minutes ago, the people he sees may be the people of the previous moment, and the things he interacts with are the same things as the previous moment. So is he not going back in time.

There are two hypotheses here,1. If he could see his past self and interact with it, then time would never be one-dimensional, nor would it be two-dimensional, but multidimensional, because this thing can be operated over and over again. Since one-dimensional time and three-dimensional space constitute one of our universes, then time in different dimensions and multi-dimensional spaces can constitute an infinite number of our universes.

2.If he can't see his past self and the interaction has a greater delay (he thinks that the interaction is with the past, but with the present, he can basically be sent to a psychiatric hospital). Then time is still one-dimensional.

To better understand this, we can give an example of a three-dimensional world and a two-dimensional world. Let's start by assuming that there are beings who live in two-dimensional planes, whose worlds are only long and wide, and who simply cannot understand the third dimension, the "high" dimension. Therefore, their perception of the three-dimensional world is limited to the projection of the three-dimensional object in the flat world, or the contact surface of the three-dimensional object and the flat world.

When a three-dimensional object comes into contact with the flat world, the fragments of the three-dimensional object in the flat world, such as the four pillars of a table and the two pairs of shoe prints printed by people on the ground, make the plane life even more confused—what do these fragments that cannot be put together mean? They couldn't imagine how four disconnected imprints could form a complete table. How can there be a complete pair of shoes on the intermittent shoe prints?

Moreover, there is a more complete person on the top of the shoe. Looking at the pieces in two dimensions, you can never put them together. <>

Time is certainly multidimensional, with planets of different sizes and different speeds.

Perhaps the whole mathematics and the whole mathematical formula are the miracles that happened in China in the Internet era, and the whole mathematical formula is different from any mathematical formula in the past in that the whole mathematical formula is also the law of the whole cosmology, which can inspire people's understanding of life in the universe

After talking for a long time, there is no question of the topic, what one-dimensional, two-dimensional and three-dimensional, that all refers to whether the space is good or not.

What time is multidimensional? The time is obviously set by our ancestors according to the law of sunrise and sunset, and people now think too much, right? ☺️

The nature of time: Time changes with the universe. Time is the dependent variable.
