I read Stephen Hawking's "A Brief History of Time" before, and I told a little story in the first chapter at the beginning, and I will narrate it next.
The scientist Bertrand Russell once gave a lecture on astronomy, and when he talked about how the earth moves around the sun, and how the sun moves around the silver heart, a little old lady sitting in the back of the room stood up and retorted: "What you are talking about is all nonsense, there is no one revolving around whom, our world is a flat plate on the back of a turtle."
The scientist then asked, "So what is this turtle standing on?" The old lady replied
You're a really smart young man, but it's not a problem, it's just that the turtles carry one by one, and finally form a turtle tower! ”
This is a very typical turtle tower model, which can be looped indefinitely as if there is no end. Some people use this model to ask what is beyond the universe? What is outside of it?
Just like this question, if our cells are magnified countless times, will they become a small universe again? There are various organelles and nuclei in the cell, and glucose and oxygen enter the cell at all times for aerobic respiration, generating some waste products and carbon dioxide to be excreted from the cell, carbon dioxide through respiration, and metabolic wastes such as uric acid through urine.
According to our conventional thinking, a matter seems to be infinitely subdivided, molecules, atoms, nuclei, neutrons, protons, electrons, etc., and with the development of the Large Hadron Collider, neutrons and protons can be knocked away and a bunch of quarks can run out. At present, according to the Standard Model of particle physics, the basic composition of matter is some point particles, and the following figure is the elementary particles in 61, including the propagators that make up matter and the basic forces, of course, gravitons are not included here.
In string theory, point particles are not the smallest structure, string theory proposes that the basic composition of matter is a vibrating string, and different frequencies show different point particles, which is that the size of these cosmic strings is very small, far below the Planck size, and the current human technology cannot detect it. So what are the strings? It's as if it's back to the problem itself, an infinite loop.
-
This could be a new universe, as it's all still circulating. Then it is likely that a new universe will appear after the cell is enlarged, which can also be said to be a figurative metaphor.
-
If you enlarge the cells n times, a new universe will naturally be formed. It's just that it's still different from the universe we live in. But then we'll have one more universe to study.
-
Of course, it's a new universe, and a cell is very small. Then there are still a lot of substances in it, and only by looking at it with a microscope, you can see that some of it is microsubstance.
-
Although the cell is too small for us to see with the naked eye, in fact, its small body contains complex structures, and we can think of it as a new universe.
-
When the cells are magnified by n times, then a new universe brings us a new and different story, so the universe is magical, and the cells are also magical.

Human cells zoom in and see organelles: mitochondria, ribosomes, Golgi apparatus and other organelles, continue to zoom in, you will see more subtle structures such as DNA double-stranded structure at the molecular level, continue to zoom in, you will see the nucleotides that make up DNA, continue to zoom in, you will see interconnected atoms at the atomic level, hand in hand to form molecules, continue to zoom in, you will see the nucleus, assuming you can keep zooming in, then you will see protons and neutrons, Up to the final elementary particle, so, whatever matter precedes it, it is magnified to the end of the elementary particle.
So, is there a bigger universe beyond what we know to be? It's hard to say. The universe as we understand it is the sum total of all information.
In this universe, the laws of physics apply everywhere. If there are other universes, will the physical laws in other universes be very different from ours? I don't know.
But Hawking argues that it is likely that the laws of all the universes will not be too far apart.
Combined with this problem, human cells do not need to be enlarged, it may be a universe, but the size is different, but our conditions are limited, too big can not be seen, too small is also invisible. We can only see things that are in proportion to our human beings. So with the human lifespan, the creatures in that cellular universe will also feel like many billions of years, just like we talk about the lifespan of the earth.
So time is also relative, related to the environment in which it is located.
The macrocosm and the microcosm are different in scale in the first place. Suppose there may be a universe in elementary particles, but the nature of that universe may not be quite the same as ours, or we can call it a parallel universe. However, this is all our imagination after all, and it is impossible to know whether it really exists, and we only hope that future scientific developments will dispel these doubts.
-
I think it's helpful in a certain way.
-
Then you'll see protons and neutrons, and finally elementary particles, so whatever matter precedes it, it's magnified to the end of a class of elementary particles.
-
There is currently no scientific basis for this.
-
I think that's a possibility.
-
Yes, theoretically, it is possible.
-
I think it should be, but it depends on the scientific research ability.
-
No, the concept of the cell is still different from the universe.
-
The concept of the cell is still different from the universe.
-
The exploration of the universe has never stopped, and it is normal to make some conjectures, because we do not know what kind of state of existence the universe is, whether it is a completely objective thing, or a living object, which is not clearThis requires the development of our science and technology to a high enough level in the future, and we can only judge it with a relatively clear understanding of the whole universe, which can only be guessed through some imagination at present.
-
I think that after the cells are enlarged, there is a universe, and there are a lot of matter compositions, so I think the universe is also a living entity, and I also think that there are other bigger things outside the universe that we have not discovered yet.
-
Human cells will not be a universe after enlargement, just because there are too few living substances in human cells, and if we say our definition of life, the universe is not a living body.
-
No. Because human cells are enlarged to a lot of atoms, not a universe. Because there is no life in the universe, it is not a living being.
-
Human cells are magnified n times, and it is a universe, and it is infinitely circulating, and there are many small substances in the cells, although we cannot see them with the naked eye, but they are particularly clear under the magnification of the microscope.
-
I don't think human cells are like this, because human cells have boundaries, but the universe has no boundaries.
-
Human cells are magnified n times and are the next universe, because the human body is made up of cells, and the human body has a particularly large number of cells, just like a universe.
-
Human cells are magnified n times, and I think this is another universe, and it is infinitely circulating, because there is also a very complete system inside the cell, there is a very sound system.
-
Yes, when a human cell is enlarged to n times or infinity, there may be a universe in it, and there may be no end to such a cycle.
-
Cells are not the universe.
Cells zoom in and see organelles: mitochondria, ribosomes, Golgi apparatus and other organelles, continue to zoom in, you will see more subtle structures such as DNA double-stranded structure at the molecular level, continue to zoom in, you will see the nucleotides that make up DNA, continue to zoom in, you will see interconnected atoms at the atomic level, hand in hand to form molecules, continue to zoom in, you will see nuclei, assuming you can keep zooming in, then you will see protons and neutrons, Up to the final elementary particle, so, whatever matter precedes it, it is magnified to the end of the elementary particle.

If you enlarge the cells n times, a new universe will naturally be formed. It's just that it's still different from the universe we live in. But then we'll have one more universe to study.
-
In the universe, the concepts of big and small are relative, and the infinite magnification of a cell of the human body seems to be a little similar to the universe we know nowTherefore, some people have put forward such a conjecture, the cells of the human body are more similar to the current universe, so is it possible that the universe in which we live may be the cells in the body of some huge organism?
From the perspective of people's perception of animals as a whole, it should not exist, because the creature of this size is completely beyond the imagination of human beings, just like the words we usually see flies, it is such a big size, but you suddenly magnify it 10 times, and it becomes a question type as big as a person, you can only think about it, because it is not a mammal, it does not have such a heart structure as a human being, and he cannot carry oxygen through blood. So if someone tells you that there is a mosquito about the size of a human and that it's still alive,If you know a little bit about biology, you will think that this is impossible.
Since it is beyond the scope of human boats, then we are not able to infer it scientifically now, we can only use our own imagination, because the structure of the atom, the structure of the universe, and the cells of the human body, there is a certain similarity between the three, so human beings have made great conjectures that the human body is composed of countless atoms, everything in the universe is like this, and then everything is made of atomsIsn't it that an infinite number of atoms come together to form a new cell body, which then also belongs to a larger organization.
The exploration of the universe has never stopped, and it is not clear that the truth of the universe is not clear, and it is naturally normal to make some conjectures, because we do not know what kind of existence the universe is, whether it is a completely objective thing, or a living object, which is not clearThis requires the development of our science and technology to a high enough level in the future, and we can only judge it with a relatively clear understanding of the whole universe, which can only be guessed through some imagination at present.
There is a huge gap in technique, physicality, expressiveness, and professionalism.
It's not a real event, but it's a real subject.
The script of "Shinjuku Incident" has been constantly supplemented and revised, and it took Er Dongsheng nearly ten years to rise, with a huge pattern and complex context, telling the rise and fall of a generation of gangsters. Although the characters in the film are fictional, each case comes from real events in Japanese Chinese society, and the overall documentary style is presented, "We have asked people in the mainland, Hong Kong and Taiwan in Japan, and all the stories are adapted from real people and real events, and there is nothing fictional. I believe that these Chinese in Japan are open to us. >>>More
