Anonymous users2024-02-05The universe is 11 dimensions.
According to the M theory (a type of superstring theory) proposed in the 90s, the universe is 11 dimensions and is made up of vibrating planes. For Albert Einstein, the universe is only 4 dimensions (3 dimensions of space and 1 dimension of time), and modern physics believes that there are 7 dimensions of space that we cannot see.
How do scientists explain the difference between the dimensions we already know and those that may exist but are not? They made an analogy: an ant walks on a piece of paper, and it can only walk right or left, forward or backward.
Neither high nor low means to it, which means that the third dimension of space exists, but it is not recognized by ants. In the same way, our world is made up of 4 dimensions (3 spatial dimensions, 1 temporal dimension), but we are not aware of all the other dimensions.
According to physicists, there should also be 7 dimensions. Although there are so many dimensions, these dimensions are invisible, they are wrapped up in each other and are called compressed dimensions. To clarify this view, let's take the example of the ant in our imagination.
We can imagine rolling up the piece of paper on which the ant walks until it forms a cylindrical shape. If an ant walks along the wall of paper, it will eventually return to the starting point, which is an example of a compressed dimension. The above phenomenon also occurs if you can walk along the famous Mebius, of course, it is 3 dimensions, but if you walk along it, you will always return to the starting point.
The Mebius belt is compressed from the perspective of dimensions, according to physics, it has three dimensions, but whoever walks on it can only recognize one dimension of people. It's a bit like the guy on the left: up or down, but never to the end.
If the ant does not walk along the curved wall of the paper tube, it will never return to its original starting point. This is the example of 2 dimensions (or the kind of dimension that we perceive), and if we follow it all the way, it is impossible to return to the original starting point.

Anonymous users2024-02-04The entire universe is 11 dimensions, and human understanding can only be understood up to 3 dimensions.
One-dimensional: There is only length, i.e., lines.
2D: A flat world with only length and width, i.e., faces.
Three-dimensional: The objective existence of the real space is the three-dimensional space, with three measures: length, width, and height. The concept of multi-dimensional space introduced in mathematics, physics and other disciplines is a scientific abstraction made on the basis of three-dimensional space.
Four-dimensional: A 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".
The 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 together with time constitutes the so-called four-dimensional space.
Five-dimensional: In this space, time may exist in a concrete linear way.
The remaining six dimensions: Humans have only explored five dimensions, while the other six dimensions are called hyperspace.

Anonymous users2024-02-03Time plus space is 11 dimensions, and the 11 dimensions of space are based on the M theory (a synthesis of various superstring theories) proposed in the 90s, and the universe is 11 dimensions and is composed of a vibrating plane.
Modern physics believes that there are still 7 dimensions of space that we can't feel, but they do exist.
Yes, the universe is four-dimensional, but three dimensions are space and the other is time. Therefore, it cannot be said that "the universe is a four-dimensional space". >>>More

Four-dimensional space-time. There are various multidimensional spaces in mathematics, but so far, the physical world we know is only four-dimensional, that is, three-dimensional space plus one-dimensional time. The high-dimensional space mentioned in modern microscopic physics is another meaning, which has only mathematical significance. >>>More
