Is the universe a random high frequency folded space?

If according to the big ** theory (this is the view recognized by most scientists), the universe is the product of the big **, so it should be limited, but it has been constantly expanding, and we don't know when it stops, whether it can stop or what happens after it stops.

As for the "boundary" of the universe, I think there is, and the "outside" of the universe should also exist, but it is limited by the level of human knowledge and understanding, and we cannot imagine and explain these contents. Let me give you a small example to illustrate this problem:

A small fish lives in the center of the Pacific Ocean, its life can not leave the center of the Pacific Ocean, in its "eyes", the surrounding sea water is its "universe", it can only "know" to this extent, it can only think that its "universe" is boundless and infinite, if a fish tells it that the outside is very big, the border between the front and back and left and right is the land, the fish will definitely "laugh" at its ignorance, but in fact, if someone fishes out the fish and puts it on the seashore, Only then can this fish know that the "cosmic space" in which it lives is really boundary, and at the same time, it can also see what is outside its "universe".

We human beings are like the "little fish" mentioned above, because we are limited by knowledge and technology (in the final analysis, it is the degree of development of the brain), we cannot find the "edge" of this space of life, so we think that the universe is infinite, if which day, which year, which one? If. If we really reach the "edge" of the universe like a small fish to the seaside, we will find that the universe is really finite, and then we can realize what is outside the universe, otherwise, human beings will never think that the "outside" is "incredible" because they cannot find the edge of the universe!

Perhaps, before the death of the earth, human beings will not be able to reach the "edge" of the universe, because there is nothing that we humans can put on the edge of the universe like catching a small fish and putting it on the seashore, but we cannot say that the "edge" does not exist because we can't reach it, nor can we say that there is nothing outside the "edge" because we can't see the "edge". The so-called "universe is infinite" can only be understood to mean that the level of knowledge relative to human beings is infinite, and it is certainly finite in substance.

A little humble opinion, welcome to discuss.

"Finite and unbounded" is a concept that is easy to understand. In a nutshell:

For a plane, it is either infinitely large or finitely large, but boundary.

But for a sphere, it is typically a finitely large surface with no boundary.

The same is true for straight lines and circles.

The above are two-dimensional and one-dimensional examples, respectively. The same applies to 3D or 4D.

But for a line in one dimension to become a circle, it has to be bent in the second dimension. Similarly, for a two-dimensional plane to become a sphere, it has to be bent in the third dimension.

Therefore, it is not difficult to understand that the universe is finite and unbounded, but it cannot be imagined, because people can only perceive three dimensions, and likewise they can only imagine three-dimensional things in their brains. The bending of the three-dimensional universe is not conceivable, it can only be expressed by mathematical formulas.

The universe is a very, very large whole, and the earth or some other star is only an extremely small part, and man is an extremely small part of a star.

It cannot be said that randomness has a certain regularity.

The universe as understood by modern science is constantly expanding, that is to say, the universe started from a point a long time ago, which is what we call the singularity (the universe is large**), and what is like outside the universe is outside the scope of our understanding.

Your questions are generally automatically categorized after writing "Know> Education, Science, > Natural Sciences".

People can't imagine thank you.

Agree with the statement upstairs and emphasize the "my question" in the upper corner

This is an assumption of modern physics.

It doesn't exist, because the argument outside the universe is absurd, we know that the universe refers to time, the universe refers to space, and the universe is the concrete form of existence of time and space, and the concept of outside the universe has no meaning, just like 0 does the divisor.

It is inversely proportional to how much we know about the universe! Other words! The less we know, the more probabilities! The more we know, the less likely it is!

I believe that aliens definitely exist.

We are not alone.

1 Secret of the Sun, 2 Mars Red Planet.

3 threats from the depths of space: 4, Jupiter, giants, planets, 5, the moon, 6, spaceships, Earth.

7 Mercury and Venus 8 Saturn - King of the Rings.

9 Alien galaxies 10 The birth and destruction of the rampant.

11 Outer Planets 12 Most Dangerous Places.

13 search for aliens after 14 big **.

It's nothing, there's no space, there's no time, there's no matter, there's nothing.

It can also be said that the universe is infinite, the universe is boundless, the beginning of the universe is also the end, the end is also the beginning, and beyond the universe is also the universe, perhaps the high-dimensional universe, or some kind of mysterious structure, or God, or God, or Elysium.

The universe is finite and boundless [like the surface of the Earth, which has a certain size (i.e., finite) but no edges. The universe is the same, it is finite, but the gravitational pull of the universe itself is so great that it bends the space in the universe back to itself (like a circle, but it is only four-dimensional). ]

Hope to adopt, thank you.

is infinite, and the universe expands at the speed of light.

I can't figure it out, something infinite, I can't imagine it.

The probability of aliens in the universe should be 100 percent. Because the universe is infinite, there are countless stars like the solar system, and there should be many planets like the earth that are suitable for intelligent beings to survive, but our human beings are currently limited in their ability to reach other galaxies to explore. This is a purely personal opinion and is not to be relied upon.

The probability of extraterrestrial life is close to 100%, and the probability of extraterrestrial advanced intelligent life is relatively low, but it will not be less than 1%.

I think it's 0%, this question first depends on the definition, you have to say that there is extraterrestrial life or extraterrestrial intelligent life in the universe, I believe it is 100% existent, the sun is just an ordinary star, there are 200 billion stars in the Milky Way, and there are more than 200 billion galaxies outside the Milky Way, which is too probable. But if you say that there are aliens, it's impossible, they can't be called human, because the definition of human beings is the definition of intelligent life on earth, just like if it's like in the Rise of the Apes movie, apes with high intelligence still can't be called humans. So extraterrestrial life must not be human, but alien species, extraterrestrial intelligent life.

Therefore I think that there will be extraterrestrial "people".

The universe has no boundaries.

The universe is infinite, because the universe refers to the sum of all material space and time, and time is infinite.

The word "universe" probably originated from the famous ancient philosopher Mozi (about 468-376 BC). He used "universe" to refer to the east, west, south, and north, and the space in all directions, and "Zhou" to refer to the time of the past and the present. Past, present, or future; Is it a recognized, or an unrecognized......In short, everything is everything.

From a philosophical point of view. It is believed that the universe has no beginning and no end, and that it is boundless. However, we are not going to go deep into this esoteric concept, and we will leave it to philosophers to study.

We might as well zoom out a little and talk about the universe that can be understood and observed using the science and technology available to us, which people call "our universe" or "total galaxy".

According to the latest observations, the farthest galaxy that has been observed from us is 13 billion light-years. That is, if a beam of light is emitted from the galaxy at a speed of 300,000 kilometers per second, it will take 13 billion years to reach Earth. This distance of 13 billion light-years is the extent of the universe as we know it today.

To be clear, the extent of the universe as we know it today, or size, is a spherical space centered on the Earth and radiated by a distance of 13 billion light-years. Of course, the Earth is not really the center of the universe, and the universe is not necessarily a sphere, but we can only understand this extent due to our current observation capabilities.

In this spherical space with a radius of 13 billion light-years, about 125 billion galaxies have been discovered and observed, and each galaxy has hundreds to trillions of stars like the Sun. So with a simple math problem, it's not hard to see how many stars there are in the universe that we've observed. In such a vast universe, the earth is really like a drop in the ocean, so small that it is insignificant.
