Is there a second space in the world? Does the universe have a second space?

Another world, do you know how you lived?

I don't know what you mean by second space, but according to the latest theories and hypotheses, there are wireless universes in the universe, and black holes are the doors of every universe, you may not be able to imagine how they exist, in fact, no one knows, can only be explained by four-dimensional space, that is, we human beings are not developed enough in their own brains, and their eyes can only see the limitations of visible light, and cannot see the four-dimensional space, but the four-dimensional space may really exist, and what I want to say here is that the fourth dimension is not time, or space.

I don't know if I can have your questions.

If you're honest, no one knows about it right now, but if you guess (and all scientists are guessing, but it's very plausible), we think there is, it's like when we all agreed that the Earth had no boundaries and then we found out that there were boundaries. And then guess, well, and through hard work, I found out that there really is, and now we're in the guessing stage, and it's the computing stage.

Some scientists have put forward this theory, but whether there is anything specific and has not been really confirmed.

There should be but it hasn't been confirmed.

By the definition of space, there is.

Some. The fourth space is the four-dimensional space.

Four-dimensional space is a concept of space-time. In simple terms, any space with four dimensions can be called a "four-dimensional space". However, most of the "four-dimensional space" mentioned in daily life refers to the concept of "four-dimensional space-time" mentioned by Albert Einstein in his "General Theory of Relativity" and "Special Theory of Relativity".

According to Einstein's concept, our universe is made up of time and space.

The fourth space is that there is an additional time axis in the structure of space compared with the three axes of length, width and height of ordinary three-dimensional space, and this time axis is an axis of imaginary values.

I believe that there is, and it may be, a space parallel to us, a fourth space that can never intersect.

Probably not. But theoretically, three-dimensional space has length, width and height. Four-dimensional space has length, width, height, and timeline. Xenodimensional? It's a wormhole. Accidentally fell into it. The world is full of wormholes.

Yes There are a lot of facts that can be said. People who enter from the cave can see what the last century was like when it was alive and more like the last century! There have been pilots who flew into wormholes and disappeared from the radar on the ground, and then appeared in the radar where the radar disappeared two minutes later, which is equivalent to two minutes when the plane flew into other space and then appeared out of the place where it disappeared, and the pilot saw the scene of World War I on Earth in those two minutes.

When the plane landed, the staff told the passengers on the plane that they didn't believe it. And then they were blinded because everybody on the plane was two minutes slower.

Theoretically, this is possible, but in practice it is not known.

There is only multidimensional space, we are three-dimensional animals, two-dimensional animals cannot see three-dimensional things, for example: a small ball fell into a hole, it seems to us like this. But in the eyes of the critter, the ball disappears. And things that are a few dimensions more than three-dimensional, we can't perceive.

I recommend you to watch more** to pass such a boring day.

Theoretically exists, to be precise, a four-dimensional space.

I don't explain one-dimensional space too abstractly, just like the situation before the birth of the universe. Two-dimensional space is equivalent to what we call plane space, only "long" and "wide", for example, ants are typical two-dimensional space creatures, it can only perceive "front and back, left and right", but not "up and down", so ants can climb walls like Spider-Man, like walking on the ground. Three-dimensional space is the world that we humans and most animals perceive, we can perceive "length", "width" and "height", but ants cannot, if you lift an ant out of a group of ants, other ants will feel that the ant "disappears" from the world they can perceive.

Four-dimensional space is "length, width and height" plus "time", if we use four-dimensional space to explain the world we can perceive, it is just a "time period", for example, I play a game online at 14 o'clock and go offline at 15 o'clock, "I" is precisely from the space of 14 o'clock to the space of 15 o'clock. "14 o'clock space" and "15 o'clock space" are relatively independent and "exist" at the same time, if I am still online at 15 o'clock, then "I" have entered "another 15 o'clock space", and I am still online in this 15 o'clock space. Four-dimensional space is difficult for us to understand, just as two-dimensional creatures are hard to understand three-dimensional space.

We human beings are three-dimensional creatures, and we can only come and go freely in two-dimensional and three-dimensional spaces (I don't explain one-dimensional), so we can infer that there are dimensional beings, then there are absolutely four-dimensional creatures, but according to Eistin's theory, if you want to come and go freely in four-dimensional space, your speed must reach the speed of light, which is obviously impossible (human beings reach the speed of light, and the body will decompose into a cellular state (and possibly an atomic state)! But I don't rule out that someone will be able to do it in the future, for two-dimensional creatures, our three-dimensional creatures are god-like beings, so it can be assumed that four-dimensional creatures look at us like ants, which is definitely not alarmist! If it's far away, just answer this, I hope these are what you want!!

I've thought about this question before, so let me tell you what I think.

Space: In fact, you should understand the word Liang separately, to be precise, space refers to, space + space, that is, space plus time.

A one-dimensional space, a point or a line, is just a simple point and line, there is no area and height, or only a length of space.

A two-dimensional space is a space where only the area exists, and there is no height, only the area.

Three-dimensional space, with length, width and height, is also the space that we have the most contact, and in three-dimensional space we have the expression of volume.

Four-dimensional space, on the basis of three-dimensional space, adds the concept of time, the space that changes volume with time, this space is also accessible to us, but its change is very slow and difficult to detect.

I still haven't understood the rest for the time being, but the word "dimension" is called "dimension" in Japan, that is, "one-dimensional" and "two-dimensional".

What kind of world do you mean by this world?

I can tell you that, as far as I know, many spaces and parallels exist.

There are countless stars, and there are countless spaces.

The world as I understand it is that there are countless kinds of parallel interfaces.
