If you closely follow developments in the world of science, the fourth, even fifth dimensions You have come across the discussions about it. If you don’t, you may be familiar with TV series and movies related to the subject.
The human brain has no trouble understanding three dimensions because the myriad variables we experience every day in our lives happen in three dimensions. Basically, humans are creatures that can easily understand the width, length and height of an object.
People can at least imagine things they can see, but not before. they have never experienced it they cannot form an image of a concept. Let’s make this more understandable by giving an example.
If you were told to imagine a color, you’d immediately think of one, wouldn’t you? What if you were asked to imagine a color that doesn’t exist?
The human brain cannot imagine a color that does not exist. Like because he can’t imagine the fourth and fifth dimensions… Carl Sagan, one of the most famous astronomers who ever lived on Earth, explains this situation in a very simple way with a video he made at the time.
The explanations may not make you understand the fourth dimension, but they do provide an enlightening way to understand why:
As you’ll see in the video, creatures have trouble imagining a dimension other than the one they’re in. We don’t have the slightest problem considering the width, length and height of objects because The dimension we are in consists of 3 components.
A being living on a two-dimensional plane can never understand or describe the third dimension. can’t imagine. Just like we can’t imagine a 4th dimension (a color that doesn’t exist) even though we want it.
So what does science say about the existence of 4th or even 5th dimensions?
Scientists are aware of the concept of time in the fourth and fifth dimensions. very different from us they say it is. While the time we experience now presents us with concepts such as the past and future, only the “now” is experienced in the 4th and 5th dimensions. It is said that our understanding of this concept is far beyond our logic.
According to the statements of the most famous scientists in the field, in different sizes Instead of the concept of time, the realities change. Events seem to move, but the concept of time, as we say, always looks to “now”. In other words, it is not linear like ours, but there is a circular flow of time in those dimensions.
To visualize different dimensions in our mind, we are helped by a form called “tesseract”:
This shape consists of two nested cubes, but the corners of the cubes appear to be connected. As Carl Sagan explains in his video, this shape watching your shadow The lengths seem to vary. This is precisely due to the difference in dimensions.
If you ask a scientist who is an expert in this field to point out exactly where the fourth dimension is, you are unlikely to get such an answer. As Sagan describes, we We live as beings trapped in the 3rd dimension. For this reason, even if the 4th dimension is explained to us, it is not possible for us to visualize it by imagining it.
The scientific world continues to conduct very exciting and in-depth studies to understand different dimensions. While everything is only theoretical for now, some calculations are that the fourth and fifth dimensions, It indicates that it can change the meaning of life. In short, the day we can understand different dimensions, it is possible that we will have a free life independent of time.
