Anonymous users2024-02-08The space around it.
The space-time we live in has four dimensions (3 spatial axes and 1 timeaxis), according to Einstein's concept called four-dimensional space, our universe is made up of time and space, and this timeline is an imaginary value axis.
Mathematical dimension. A point is 0 dimensions based on a point, a point is 1 dimensional based on a straight line, a point is 2 dimensions based on a plane, and a point is 3 dimensions based on a body.
Straight lines are 4 dimensions based on planes, 6 dimensions based on volumes, and 9 dimensions based on planes."
Physical dimension
For example, two parallel lines can be regarded as two relatively independent one-dimensional spaces, and in order to get from one line to the other, a new line needs to be established to connect the two, and this line is the dimension. Dimension 0 is a point and has no length.
1 dimension is the line, only the length. Dimension 2 is a plane that is made up of length and width (or curves) to form an area. 3 dimensions is 2 dimensions plus height to form volume.

Some theories predict that the universe we inhabit actually has more dimensions (usually 10, 11, or 26). But these additional dimensions measure the subatomic size of the universe. Dimensions are theoretical models, and this is more evident in non-classical physics.
So you don't care what the dimensions of the universe are, as long as it's easy to describe.

Anonymous users2024-02-07Physically, according to string theory (a new theory, introduced in Hawking's popular science book), the world really exists in 10 dimensions, three spatial dimensions, one time dimension, and six undimensioned dimensions curled up in the nucleus of the atom.
Theoretically, there is no upper limit to dimensions, and at least at present, there should be no theory that can prove that there is an irrationality or contradiction above 10 dimensions.
In terms of mathematical dimensions (non-real dimensions), there is no upper limit at all, because this is something that is prescribed by the individual, and you will understand what this means when you learn the multidimensional space in advanced algebra or linear algebra.

Anonymous users2024-02-06There are four dimensions that we can feel, including the dotted timeline. This is also Einstein's four-dimensional space theory, three-dimensional objective existence can be felt, and time is nothingness, we know that the classical theory of relativity is to talk about time ......But many physical theories need to recognize more dimensions, such as superstring theory, which requires dimensions of 10 ......The universe is expanding, elementary particles are condensing in various forms, so theories are being disproved at various speeds......This is a world of elite research, a wonderful world. If you are interested, you can find more books to read, and you will understand the world better.

Anonymous users2024-02-05Dimensions should be an inclusion of "attributes, scopes, coefficients, and affordability". Refers to different meanings in different objects.
For example, the dimension of the universe, the dimension of steel, and the dimension of an event each refer to the expansion coefficient of a certain field of its own.
The psychological dimension is the ability of a certain aspect of the psyche to bear and how flexible it is to scale in such an event. Beyond this dimension, what changes will occur in this regard, etc.

Anonymous users2024-02-04Dimension, also known as dimension, dimension, and dimension, is the number of independent parameters and degrees of freedom of the system, and in physics and mathematics, the dimension of mathematical space is informally defined as the minimum number of coordinates required to specify any point in it.
Dimension 0 is a point and has no length. 1 dimension is the line, only the length. Dimension 2 is a plane that is made up of length and width (or curves) to form an area.
3 dimensions is 2 dimensions plus height to form a "volumetric surface". Although the average person is accustomed to the integer dimension, in fractals the dimension is not necessarily an integer, but may be a non-integral rational number or irrational number.
The space around us has 3 dimensions (up and down, front and back, left and right). We can move up and down, southeast and northwest, and the movement in other directions is only represented by 3D space axes. Moving down is the same as moving up in a negative direction, and moving northwest is just a mix of westward and northward.
In physics, time is the fourth dimension, and unlike the three dimensions of space, it has only one, and it can only go in one direction.
The space-time we live in has four dimensions (3 spatial axes and 1 time axis), according to Einstein's concept called four-dimensional space-time, our universe is made up of time and space, and this timeline is an axis of imaginary values.

Anonymous users2024-02-031. A plane can be seen as a collection of points, so there are points (infinitely many) in a plane
2. In the plane, establish the plane coordinate system, then the points in the plane can be represented (or determined) by a pair of real numbers (x,y).
3, same as 2; By the way, "visible" is a concept that has no mathematical meaning.
There is a theoretical upper limit, and mammals live 7 to 8 times as long as they are sexually mature. In the 2016 study, Jan Vijg, a molecular geneticist at the Albert Einstein College of Medicine in the United States, and colleagues analyzed global demographics over the past century and confirmed that the maximum age has remained around 115 years since the mid-1990s. Based on these results, the authors concluded that the natural age limit for humans is 115 years, and that the probability of people surviving beyond 125 years is less than 1 in 10,000. >>>More

From two sides of your problem.
First of all, restructuring can only allow you to gain traits that already exist, such as the strength of a bear, the speed of a leopard, and the eyes of an eagle. But if you want to get a new trait, you have to wait until the gene is mutated, or you have the ability to create new genes, like God. >>>More
This, I don't know what era of theory you are looking at by that Da Liu. Obviously, that theory has been rejected by practice, because what it deduces contradicts the facts, so even if this theory has ever appeared, it is still an abandoned theory. >>>More
Theoretically, human beings have achieved space odyssey, but it will be at least 50 years after ordinary people's space odyssey with the current level of scientific and technological development.
