In addition to the tall and mighty future high-tech images such as Iron Man and Superman in the Marvel Universe, there are also "Ant-Man", which is the size of an ant, but also a very powerful character.
The "Ant-Man" in the movie is so powerful, but in reality, many scientists say that ants are a two-dimensional creature, and many experiments have been done to demonstrate it.
For example, with a pen to draw a circle with an ant as the center of the circle, the ant will be disoriented, rampage but can not get out of this circle, the original ant's vision is not very good, its eyes can only see the flat two-dimensional world, most of the time it is using the sense of smell and the antennae above its head to distinguish the direction.
The world in the eyes of ants is two-dimensional, so are ants two-dimensional creatures?
As we all know, ants are actually three-dimensional in the eyes of humans, not a flat line or a point, although in the eyes of humans, the body of the ant is very small, but the appearance is still three-dimensional.
So is there a four-dimensional space in the universe, and what do we think of as three-dimensional human beings look like in the eyes of four-dimensional space creatures?
In 1905, Einstein published a number of papers on special relativity, and since then he has continuously demonstrated the scientific nature of relativity, on the basis of which he proposed scientific ideas such as "four-dimensional space-time" and "relative space-time theory". Most of the various dimensional space theories that emerged later were based on Einstein's theory of relativity as the first theory.
And today we will talk about the concept of multidimensional space, to see if ants are two-dimensional creatures? And is there a multidimensional space in our world?
<h1 class="pgc-h-arrow-right" data-track="16" > ant physiology and related studies </h1>
As mentioned earlier, although ants have compound eyes, they are not as useful as human eyes. Its compound eye vision is not only extremely limited, but it can only see the flat world, so it cannot see the existence of humans at all.
That is to say, in the world of ants, there are flat things such as points, lines, and surfaces, and the world it sees is two-dimensional. For example, a straight line we see might be a high wall in the world of ants.
There are many types of ants, and the physiological structure is not exactly the same, we mainly talk about the physiological structure of ants from most of them.
In terms of body size, ants are relatively small, of which male ants and queens are larger, so they have a high status in the colony.
In terms of color, ants have many colors such as red, black, and brown.
In appearance, the ant has six legs, and the appearance of the ant tentacles is not very obvious to the naked eye, but the tentacles are one of the important parts of the ant, the entire antennae are about 4-13 segments, and the length of the antennae of different types of ants is also different.
Most ants live in underground nests, but there are also flying ants, which have wings and live in different areas.
For years, scientists have been working on how ant colonies work together, and what exactly ants use to communicate in the colony, accurately completing their tasks in their daily work.
Scientists have found that because the compound eye of the ant can only see the two-dimensional world, the ants in daily life mainly rely on sensations in communication, especially in hearing, smelling, and touching.
You may wonder about this sense of hearing, can ants talk?
Of course not, ants mostly rely on external objects, such as knocking on wood or rubbing to make sounds. How do I tap to make a sound? When the worker ant encounters a crisis in the nest, it will swing its body back and forth on the tree at the top of the nest, colliding with the tree, thus making a sound and warning the ant colony of the danger.
Friction sound is that ants will rub their abdomen with the body organ "file" to make a sound. So the ants don't speak, they don't have their own language, and the sound here is more like a fixed signal.
Ant touch mainly relies on the antennae, as mentioned earlier, friction when hearing sounds is to send signals, then the antennae are to receive signals, and the ant's tentacles can smell the smell of the companion and identify the companion when it comes into contact with the companion.
In this way, after the tentacles contact the companion, an invitation to the companion to carry the grain together can be issued, and after the other party receives it, the inviting ant will leave a smell on the way to the grain so that another ant can carry it.
<h1 class="pgc-h-arrow-right" data-track="43" > the way ants move on a daily basis </h1>
In addition to doing a lot of research on the ants themselves, humans are more curious about the daily cooperative lifestyle of the colony. Because the ants themselves have no brains, without the brain, they do not have the ability to think, but if there is no ability to think, how can they achieve that within the ant colony, each ant can perform its own duties and unite to maintain the life of the ant colony?
American scientists were curious about the behavior of ants similar to human populations, so they studied the genetic sequences of ants in detail.
The results of the study really shocked scientists, because they found that ants have up to thirty percent of the genetic sequences that are the same as human genes, and this discovery seems to show that the way ants cooperate is determined by a part of genes, because humans with the same genes will also cooperate to live together.
Rheinberg, the author of the study, said: "The life of each ant in the population starts from the same origin, and their genetic structure is the same. Thus causing them to make very different brain signals that correspond to their social class behavior must be determined by epigenetic mechanisms. This finding could help us better understand the effects of epigenetics on human brain function. ”
Chinese scientists have found that the social behavior of ant colonies is closely related to the neuropeptide genes of ants, and in the research work, they put two different ant colonies together to study, and finally found that their neuropeptide genes are basically similar.
This is why ants around the world have teamwork social behavior despite their different locations, and scientists speculate that this type of neuropeptide gene has existed in ants in ancient times and has continued to this day.
<h1 class="pgc-h-arrow-right" data-track="56" > ants are two-dimensional organisms </h1>
As mentioned earlier, just because the compound eye of the ant can only observe flat organisms, can we conclude that the ants are two-dimensional organisms? Obviously, no, because the paradox is that ants are three-dimensional in the human eye, with three-dimensional properties, so ants in human eyes are three-dimensional creatures.
The origin of this statement should be that it stands on the side of the ant, because the world it sees itself is two-dimensional, so if the ant has thoughts, it should take it for granted that it is a two-dimensional creature, which is consistent with the world it sees.
Just like us humans, we live in a three-dimensional dimensional space, and the world we see is three-dimensional, so we think we are three-dimensional creatures.
This is probably ten thousand Hamlets in the eyes of ten thousand people, and what we are, what dimension of space we are in, depends entirely on how we see the world.
So two-dimensional, three-dimensional, or even four-dimensional, is uncertain, relatively speaking.
If we must argue whether ants are two-dimensional creatures from the perspective of the original organism, then the most scientific and reasonable statement should be, "In the world of ants, it is a two-dimensional creature, and in the human point of view it is a three-dimensional creature." ”
We are curious about what the world is like in the eyes of ants, ants without brains only rely on tactile hearing to work in a world full of lines to survive, carrying food on time every day, exploring routes, even if there is no wisdom but have been insisting, I have to say that life has always been a tenacious existence.
<h1 class="pgc-h-arrow-right" data-track="71" > human vision and research on multidimensional space </h1>
The mention of multidimensional space refers to the human definition of the concept of space-time.
In the period of formal enlightenment, the first time that human beings viewed the concept of space-time from a scientific perspective should be in the period of Newtonian mechanics. At that time, people thought that time was like an ever-expanding line, it was flowing, but we couldn't see it. And it is believed that time and space are relative, and there is no interweaving between the two. Obviously, this view is very one-sided.
Later, after Einstein put forward the famous theory of relativity, people had a new understanding of the understanding of time and space, and Einstein's theory of "bell slow" and "ruler contraction" in special relativity clearly stated that there is a close relationship between time and matter in space, and the two are closely related, and have always coexisted.
The proposal of this theory holds that the world in which time and space are integrated should be "four-dimensional space", which is also the first time that human beings have put forward a vision for multi-dimensional space.
Time in four-dimensional space is no longer a single linearity, but has an extension like a "surface", and under certain conditions of material motion, time can be frozen and stationary at a certain moment.
The exploration of four-dimensional space in general relativity goes one step further, and if time and space in special relativity are straight, then general relativity is curved.
The strong gravitational field causes them to bend, and the stronger the gravitational field, the stronger the bending will be. And in this curved space-time, humans may achieve space-time travel.
In the 20th century, in response to the emergence of new concepts in the concept of space-time, Prigogine proposed the "dissipative structure theory".
Prigogine introduced the new concept of time, "internal time", which is closely related to the evolution of systems, which is a measure of the degree of evolution of systems. It is a kind of "evolutionary time", which is the internal driving force of the evolution of all systems. Corresponding to the internal time is a space with organization and function.
This understanding is based on the more in-depth understanding of the four-dimensional space of relativity, which he believes that all comparisons in the four-dimensional space are relative, but the motion of the system is in an absolute state.
In today's twenty-first century, it is believed that time and space are organically integrated in a fixed formula to form the whole of four-dimensional space, and four-dimensional space is the unity of relativity and absoluteness.
<h1 class="pgc-h-arrow-right" data-track="93" > the possibility of space-time travel </h1>
For hundreds of years, human beings have been very enthusiastic about traveling to the future world, and after the emergence of the theory of relativity, this yearning and fanaticism for crossing has reached its peak. Christopher Nolan's film Interstellar embodies the possibility of humans crossing time and space.
For the first time in the film, the image of the film shows people that the five-dimensional space in human cognition now has time, which we have not been able to see and touch, but has been deeply affected, in the five-dimensional space in a state of matter, like a huge bookshelf, the pillars of time and the events that occur in space are closely intertwined, and this time time time can be seen and even touched.
It is true that as a three-dimensional creature, even if human beings have developed brains, our understanding of the existing world is still limited, let alone the vast universe.
However, adhering to the spirit of exploring the unknown, human beings have always made new discoveries about dimensional space. I don't know if there is science in the world of ants, and perhaps where we don't know they are also actively exploring our world, and in their world we are a high-dimensional civilization.
<h1 class="pgc-h-arrow-right" data-track="104" > multidimensional spatial organisms coexist </h1>
For ants, humans are highly intelligent beings. However, human beings are not a grain of dust for the vast cosmic world, but may only be a short moment in the evolution of the long universe.
We may have been coexisting with creatures of different dimensions, and sometimes we perceive each other's presence without disturbing them too much. The world is a pluralistic whole, and we are eager to explore more unknown areas and to coexist with creatures in multi-dimensional space.
