Are there four or how many universes are there or are there only one universe or many universes?

Some cosmologists believe that our universe is the only one; The big ** is not in any point of the universe**, but the entire universe itself**. However, the newly proposed inflation model suggests that our universe is only a very small part of the entire inflation region, which is larger than 1026 centimeters, when our universe was only 10 centimeters. It is also possible that this inflation zone is part of a larger system of matter that began in a state of irregular chaos.

Just as in the history of science, human understanding has expanded from the solar system universe to the galactic universe and then to the large-scale universe, and today's science is trying to further move human understanding to some kind of "skyrocketing universe" and "irregular chaotic universe" in exploration. Our universe is not the only universe, but part of some larger system of matter, and the big ** is not the whole universe itself, but a part of that larger material system. Therefore, it is necessary to distinguish between two different levels of the concept of the universe, philosophy and natural science.

The philosophical concept of the universe reflects the infinitely diverse and eternally developing material world; The concept of the universe in natural science deals with the largest celestial system that human beings have observed in a given era. The relationship between the two cosmic concepts is that of the general and the individual. With the development of the concept of the universe in natural science, people will gradually deepen and approach the understanding of the infinite universe.

Clarifying the differences and connections between the two concepts of the universe is of positive significance for upholding the Marxist theory of universal infinity and opposing the theory of universal finiteness, creationism, mechanism, agnosticism, philosophical substitution, and cancellation.

From Hawking's theory, we know that there is not only one universe, but there may also be several parallel universes or multiverses.

1 pc. Science is not as advanced now.

Space is infinite, matter is infinite, energy is infinite, the universe is defined, time has no beginning and no end, how much do you think it should be?

Today's technology doesn't tell.

There should be more than that, there are many substances in the universe, but what we can see and detect is very small, and there are many unknowns.

There is only one universe, and it is the collective name of the whole space.

B.C., the ancient Greek scholar Eudox put forward the idea that the sky is round and the place is round, that is, what we call the geocentric theory, and later the advent of the Copernican heliocentric theory overturned this view, and also made people realize that the place where we live is a planet in the vast universe, and beyond this planet, there are many such planets. Later, with the development of this technology, scientists observed other stars in the solar system through astronomical telescopes, and Galileo was the first astronomer to discover the details of the celestial bodies in the solar system.

When Galileo used a telescope to observe the starry sky, he proved Aristotle's view that "the sky is round and the earth is round" wrong, and also confirmed that the Milky Way is a collection of stars. The universe is vast, and the splendid universe in Hubble's eyes.

The above is the process of human exploration of the universe, when people asked what was beyond the earth, there were many large and small stars outside the earth that made up the solar system, and there were many such star systems that together formed the Milky Way. Now back to the question, what is beyond the universe? Although the current level of science and technology is not yet enough to explore the universe, or even the universe has not been fully explored, since this question is asked, we can boldly guess that there may be various different universes large and small outside the universe.

Although the current level of science and technology is not yet up to the level of exploring things outside the universe, I believe that in the near future, our footsteps will definitely set foot outside the universe and explore the mysteries outside the universe. Mankind's exploration of the universe has never stopped. Since the invention of the telescope, people have gained a better understanding of the observation of the universe and realized that the Earth we live in is not the center of the universe, and the Milky Way is not the center of the universe.

The universe is unimaginable. The existing observation technology is still very limited, and it is impossible to see the whole picture of the universe.

There is only one universe.

The universe is a big generalization.

Just like the whole world of the earth, it includes all countries.

The universe refers to infinite space-time. The corpse of the Warring States period (390 BC 330 BC) proposed in "The Corpse": "The four directions are called the universe, and the ancient and modern are called the universe."

According to the definition of the concept of the universe, there is only one universe, and the universe can be divided into observable and unobservable universes. The observable universe is an area that humans can observe, with a radius of about 13.8 billion light-years. The unobservable universe is an area that cannot be observed by humans, with a radius of more than 13.8 billion light-years.

You're talking about the "bubble universe" hypothesis. This hypothesis was proposed by physicist Andre Lind. The content of the hypothesis is roughly as follows:

In a certain space, there are countless universes, just like bubbles, human beings are only in a bubble, and current technology cannot detect the edge of the "bubble" we are in, so this is only a hypothesis, and it has not yet been confirmed.

There are many hypotheses in the scientific community about you, but none of them are certain. So there is no exact answer at the moment.

According to the current level of science and technology, only one universe can be detected, and in science fiction**, there may be countless universes, but it cannot be confirmed yet.

To think about this question, first figure out what is the meaning of the universe? What is the scope of the universe? Figure this out. The meaning of the universe can be formulated according to this question. Thus knowing how many universes there are.

There is a universe for only finch.

The universe is a general term for the vast space and the various celestial bodies and diffuse matter that exist in it, and the mainstream view in modern cosmology is that the origin of the universe originated from a large **, which evolved from a state of extremely dense and extremely high temperature in the past, and reached a state through continuous expansion, which is called the grand theory of the universe or the theory of singularity.

Although the size of the entire universe is unknown, the size of the observable cosmic rock can be measured, which is estimated to be 93 billion light-years in diameter. In various multiverse theories, a universe is one of the components of a multiverse on a larger scale, and each universe itself includes all of its space and time and its matter. With the gradual improvement of the level of sky survey observation technology, human beings continue to try to draw the whole picture of the entire universe.

Earth: Earth is a planet in the solar system and is inhabited by humans.

The Earth is an irregular oblate sphere. The combined effect of the uneven distribution of mass in the Earth's interior and the centrifugal force generated by the Earth's rotation makes the Earth's natural surface extremely complex. Therefore, it is common to think of the mean sea level and its continuous extension to the land as a geoid level.

How many dimensions is the universe? You may need to count well.

Concern. At present, in our understanding and cognition, the universe is a four-dimensional space-time, three-dimensional space plus one-dimensional time, a little more academic to take out a Cartesian coordinate system x, y, z axis plus a time, in daily life is up and down, front and back, left and right plus a time. This model is easy to understand in our minds.

The two-dimensional space, one-dimensional space, and even zero-dimensional space that are lower than the three-dimensional space are relatively easy for us to understand, but the higher-dimensional space is not figured out in our brains. For example, how to understand the extra one-dimensional space in four-dimensional space? Should I put it in?

Although we can't imagine what high-dimensional space looks like, mathematical tools can! In the sixties of the last century, by chance, string theory appeared, the Italian theoretical physicist Viniziano was studying the various properties of the strong nuclear force, and accidentally used Euler's formula more than 200 years ago to describe the properties of the strong force, but everyone could not figure out the internal reason, until 1970, the University of Chicago's Nanbu Yoichiro, the Bohr Institute's Nelson and Stanford University's Suskin revealed the secret hidden behind Euler's formula. If one-dimensional vibrating strings were to simulate elementary particles, then their strong forces could be described by the Euler function, and string theory originally held that the universe was 26 dimensional.

However, with the development of high-energy experiments, it has been possible to explore the deeper subatomic world, and experiments have shown that some of the numbers predicted by the string model contradict actual observations. This theory was gradually forgotten until the 80s, when the first revolution in string theory began to emerge with superstring theory, this time the theory that the universe is 10 dimensions space.

In the nineties of the last century, a new theory M theory was developed in superstring theory, which is the "cutting-edge product and essence" of string theory. The M theory believes that the universe is 11-dimensional space-time, which means that except for the four-dimensional space-time on the macroscopic level, the extra 7-dimensional space is all curled up together, which may be on the Planck scale, which cannot be observed at all by current observation technology. For example, from a distance, the wire looks like a one-dimensional line, but at close range, the line is still three-dimensional.

The universe is infinitely large, and the number cannot be determined.

The universe is not infinite, the universe is infinite, you can't imagine it?
