First, I read the comments on this question. People answer something, discuss it. But no one understood the question itself. Whatever the universe is, anything can appear in your imagination. The question is not posed correctly. It's like, - If the Tennis Ball is round, does that mean there is a banana ..........

Only imagination can appear in the imagination! The universe itself is imaginary as well as its infinity is also imaginary, in reality there is neither universe nor space, since only on the screen of reality can imaginations arise, that is, illusions, and there is no place in the imaginations of reality, this is how images can appear only on the screen, according to this movie on the TV screen is the director's imagination enclosed in light, and only the screen on which this light depicts the movie is real !!

No. Everything that we can add has not the slightest connection with reality, and the more we study reality, and not invent objects such as the Lord, Angels, the soul and the afterlife, the faster we will come to the immortality of man.

Answer 4

The question is very difficult, it goes beyond physics itself into the borderline area of ​​philosophy. The answer to it depends on the answers to two other questions:

  1. Is the universe infinite (both in space and time) and
  2. What do we mean by the word "exists"?
    The first question relates to the field of physics (astrophysics), but there is no exact answer to it yet. Almost all physicists now agree that our universe began more than 14 billion years ago and that the early stages of its existence were very different from its present state. But there is no certainty about its size in space (is there something outside the visible part of the universe) and further fate (in the future tens of billions of years), there are different models - and in the coming billions of years, they will probably change a lot more;).

If the universe is still infinite in space or time, then yes, any situation will repeat itself many times, as Nietzsche pointed out. If not, the answer to the second question becomes important. The fact is that from the point of view of quantum mechanics, we can talk about the Multiverse - the set of all possible states of the Universe. The elements of the Multiverse do not interact with each other, which makes it impossible to move to or from the "parallel universe", which is so popular in science fiction literature. But the universe itself is constantly moving from one state to another, "traveling" through the Multiverse.

Accordingly, if by the word "exists" we mean "exists in our universe", then in a finite in time and space of the universe, not all possible situations are realized. If we mean "exists in the Multiverse" then, apparently, everything.

The universe has not come from anywhere, and will not go anywhere. It is endless. She was not excited and she would not die. And any of its properties. Man is her property. Bearer of feelings. Able to change himself and his genetics. How many times does it go on forever? Probably endless. Feeling is an eternal property of the universe.

Answer 6

If you do not take into account the fact that the Universe is recognized as not infinite, then I would answer that everything that you have presented, provided that it does not contradict the laws of physics, is.

There is a theory of an immortal monkey: if to put an immortal monkey to a typewriter, that is, there is an infinitely small probability that she will ever write "War and Peace" on it, or any other work (s). Also here: if the Universe is infinite, then there is also an infinitely small (but it is) probability that the object you represent exists.

Answer 7
May, 2021

No, because from the point of view of elementary logic / mathematics, infinity is not "anything".

Take numbers as an example. In the range from one to two, there can be any decimal fraction with an integer "1" ie infinite number of digits. But not three, not five, not ten there cannot be. It is the same with the infinite universe - anything can be in it, but only within clearly defined boundaries. These boundaries are set by the initial physical parameters, and it will not work to go beyond them without going to another universe (parallel).

ru.wikipedia.org even more interesting is the formulation of the question, some theorists have been racking their brains about it for a long time :)

Answer 9
May, 2021

Even if we assume that our Universe is infinite, the answer is no, since imaginary objects from our consciousness can violate the laws of physics, and the size of the Universe will not affect this in any way.

If our Universe is still infinite, then if we move away at a sufficient distance (say 10 ^ 10 ^ 70 meters), then the objects will start repeating, due to the fact that the combinations of Planck states will simply end, accordingly, if the Universe is infinite, then there will also be an infinite number of repetitions.

If we adhere to the concept of the multiverse, then we can assume that in some of them other laws of physics will operate and our imaginations will be real, here only it won't be us, but our copies

Something like this

Answer 10

The universe is finite, according to the theory of the big bang (space is possible infinitely), it is worth digging towards the theory of the multiverse, then yes, everything is possible there, but not all physicists consider this theory even plausible, but again not all "physicists "once shared the idea that the sun is in the center in our system, then the scientific world turned the fact that the universe is expanding faster and faster, and not slowing down the expansion, and this is one of the three pillars of the theory of the multiverse, which by the way was created and developed by our compatriots ... # postwater offer

Answer 11
May, 2021

According to the ideas of modern physics, the universe is not infinite, but if you start from the question, then the answer is also no. In an infinite universe, most likely there will be only everything that can appear and exist in accordance with the laws of physics, but here we still need to clarify - the substance is also finite, and in large parts of even our finite universe there is no this substance, which means that there is nothing there (although a huge space is filled dark matter)

Answer 12
May, 2021

Things may appear in my imagination, the existence of which is impossible in accordance with the laws of physics known to us. But the laws of physics known to us extend and work not only within our galaxy, but are applicable to the entire known universe. Until now, there have been no prerequisites that in some parts of the Universe the laws stop working or work differently. This means that the same laws of physics work in unobservable parts of the Universe. Therefore, regardless of whether the universe is finite or not, it cannot be argued that there is any object in it that can appear in your imagination.

But if we assume that the theory of the multiverse is correct, and different universes have different laws of physics and there are an infinite number of such universes, then, of course, absolutely everything that can (and cannot) be imagined can exist.

There is an assumption that the universe is a hologram. http://www.vesti.ru/doc.html?id=1166955

http://laser-portal.ru/content_425

It turns out that everything is upside down , only that which already exists can appear in your imagination. You yourself can essentially be a projection (invented in the imagination), only for another observer. As well as infinity and finiteness (Planck's value) - the same is essentially just an invented value of our consciousness as an observer of this phenomenon.

Answer 14
May, 2021

The universe is not infinite.

But, if it were infinite, then any events that have already occurred and can happen, and an infinite number of times, could occur in it.

I believe that the question of whether events that violate the laws of physics could then occur is metaphysics, as is the very existence of an infinite universe. Science cannot yet give an answer to this.

But if you expand your question to the Multiverse, then, assuming its existence, we can assume that there are universes with different laws of physics, where the events of your favorite books take place. And there are an infinite number of such universes.

Answer 15
May, 2021

Michio Kaku's book gives a very good idea of ​​the infinity of the universe.

Think of the universe as the surface of the Earth. Its area is finite, but if we go in one direction, then we will never reach the end, but sooner or later we will return to the starting point. The same is with the universe, but only with the condition that it is three-dimensional. So the volume of the universe is finite, and the existence of any object in it is impossible. But there are still parallel universes!

But these are only theories, and how it really is nobody knows.

Answer 16
May, 2021

The answer is obviously no. Because infinity does not imply an enumeration of the entire universe, everything and everyone.

Well, imagine, for example, a chain of colored balls and your endless supply of these in a box, let there be seven colors for convenience. And you endlessly add and add balls, hoping to get All Chains of Balls ... But bad luck, when you add another ball, at least 6 more variants of chains open, where at the end instead of yours there is a ball of a different color. Etc.

Guys, infinities are different. One infinity may not include particles of another at all, for example, natural numbers and regular fractions :) This is so, if you don't find fault with the definition of consciousness and imagination.

Answer 17
May, 2021

Yes, if the universe were infinite, then it would contain absolutely all possible combinations of matter. So any object, whether invented, invented, or unreal - it will exist.

I once liked the example with the number PI. It is a number in which its decimal representation never ends and is not periodic. And if you take each letter in the alphabet, represent (encrypt) numbers from 0 to 9, then among the PIs you will meet FULLY any of the books written earlier and any of the books of the future. And in general, whatever you encrypt (picture, film, song) with numbers, it ALL will someday be in the decomposition of the number PI completely. That's what infinity is.

Unfortunately (or fortunately), infinity is just mathematics. It is only in our minds and has nothing to do with our world.

Answer 18
May, 2021

Consciousness is inside the universe, acts according to the laws of the universe, is a part of the universe. The word infinity appears in consciousness under the influence of external causes. It did not arise by itself from the void there. Certain events had to happen that caused the emergence of an understanding of infinity. That is, consciousness must first go to a kindergarten, then to school, then read some book, and only then understand what infinity is.) That is, infinity in consciousness is an approximate copy of real infinity, as if its small passport. To understand real infinity, consciousness would need to be as infinitely large as the universe and fully reliably reflect it.

If existence is a manifestation as a cause of effects, then any imaginary object exists. For example, I will come up with some kind of illusion (of a flying hippo), someone will go to the site, read about the illusion, realize, will laugh for a long time and skip breakfast. That is, the illusion has become the cause of the effects in reality. It turns out that these consequences cannot be ignored. This is not to say that the illusion does not exist at all. The illusion arose for some reason and itself became the cause of some consequences. That is, it became a link in the chain of existence of phenomena ...
