Why can t four dimensional space communicate with three dimensional space?

This is because the dimensions are different, so contact cannot be made, and there is no way to have too close contact, so there is no way to communicate in space.

Because these are two dimensions, there is a barrier in the middle, we can only observe and not talk, just like we can see the two-dimensional world, but the other party is not aware of our existence at all.

Because there are many differences between four-dimensional space and three-dimensional space. What seems simple in four-dimensional space is incomprehensible in three-dimensional space.

I think it's because it's not in the same dimension, just like a person can't communicate with a dog.

The world we live in is a three-dimensional world, a world made up of bodies, and almost everything will look like it, but intelligent scientists are wondering what the world is like outside of the earth. Based on a variety of experiments, scientists have discovered a hidden world, that is, the world of time, which many people think does not exist, it is only an objective definition of people. In fact, scientists are aware of the existence of time periods.

The duration seems to be disturbed and changed, and time is one, which means that there is another invisible dimension of duration in the three-dimensional indoor space, and time seems to suffer from the harm of quality, and the greater the quality, the greater the harm. And the universal existence of time-hazardous objects in space, whether it is a superblack hole or a neutron star, confirms the scientists' conjectures. Therefore, scientists feel that people's cosmic space is a four-dimensional world.

Our cosmic space is a four-dimensional time composed of three-dimensional indoor space and duration, although people's perspective at this stage is only in three dimensions. However, scientists have determined that if people go into the fourth dimension of time, they may be able to see some wonderful objects, such as time.

Three-dimensional space is the level of clothing, food, housing and transportation that we have now, and the fourth dimension is usually called time, and the timeline is equal to an endless length of pipes, and we are a cube in the tube, and we can't enter the fourth dimensional space now, which means that we can't understand the objects in the two-dimensional space, they are only the length and width, and everyone thinks that there are no microorganisms in the two-dimensional space, and this is the limitation of three-dimensional space creatures. If one day you can find a safe passage from the third dimension to the fourth dimension, you will be able to travel through time and space.

Some people say that the fourth dimension is a body (or superbody), and there is basically an extra dimension in the three-dimensional space, but no one can say what this dimension is. In addition, one narrative method is to think that the high-dimensional space is a fitness exercise in the low-dimensional indoor spaceFor example, a two-dimensional space (surface) for fitness exercises establishes a three-dimensional space. In the same way, fitness in three-dimensional space establishes four-dimensional space, and so on.

The point is that we are now in three-dimensional space. If you want to enter the four-dimensional space, you have to change quantum mechanics.

That is to say, entering the thinking space is where real human beings live, and our human thoughts are three-dimensional, but in fact there is another scene of life, which is four-dimensional.

It's because the place where we humans actually live is a three-dimensional space, but there is also a parallel space, which is a four-dimensional space, and there is another group of people living there.

In simple popular science language, one dimension is a point, two dimensions are a filial piety plane, three dimensions are a space that exists in length, width and height and distinguishes between inside and outside, and four dimensions is also a space, but because four dimensions have one more direction than three dimensions that we can't imagine, so looking at three dimensions from four dimensions, we can directly see the inside of Naqin's three-dimensional space, and can directly see the things in the box without opening the box, and even take it out.

For example, when we take away a piece of candy placed in front of an ant's eyes, the candy disappears out of thin air in front of an ant that is similar to a two-dimensional creature that has been sold.

In four-dimensional space:

From the perspective of any dimension, three dimensions are a three-dimensional image, but they are different three-dimensional images, just as we can see the front, the top and the side when we look at the three-dimensional world, and in the eyes of people in the three-dimensional world, the two-dimensional world is a collection of countless lines (one-dimensional world), then in the eyes of people in five-dimensional space, the four-dimensional world is also a collection of three-dimensional worlds, so we can know that the dimension of high-latitude space is more than that of low-latitude space, which can be used to observe low-dimensional space.

This is what is called "vertical" in mathematics. As long as we figure out how to replace the three-dimensional plane image we see in the three-dimensional world with the three-dimensional image, we can find the extra dimension in the four-dimensional space.

At present, very few people know the term four-dimensional. But for those who know, there are three theories of four dimensions as far as I know.

The first is linear mathematics, which is a space surrounded by four straight lines perpendicular to each other in a space.

The second is the superstring theory, which is a space made up of four strings smaller than the "quark" plasma.

The third is Einstein's theory of relativity, which is three-dimensional space plus a time axis.

As for which theory can be accepted by the general public, at the moment, this theory is very abstract, and most people who know about it tend to favor the third type. Hope it helps.

The n-dimensional space is formed by an infinite number of n-1 dimensional spaces arranged in a certain way. Just like the space we live in, we humans can perceive three-dimensionality, we can draw a face, we can draw a line, a point. This is the projection of a low-latitude object in a high-dimensional object.

And if we draw a three-dimensional figure on a piece of paper, then this is the projection of a high-dimensional object on a low-dimensional object. This kind of projection simply allows the shape of a high-dimensional object to be represented in a lower dimension. Because humans can perceive three dimensions, and ants can only perceive two, even if we draw a three-dimensional figure on the paper they crawl on, it will only think that it is just some lines.

Because they can't perceive three-dimensionality. Human beings may live in four dimensions, but they can only perceive three. Perhaps, to borrow the theory of relativity, we live in a four-dimensional space with the passage of time around us, which may be a new dimension, but it is beyond what we can perceive, so there is no such thing as a low-dimensional object that can perceive a high-dimensional object.

What is the difference between three-dimensional space and four-dimensional space? And how to understand it? After reading it, my brain was opened.
