No object in the world is ever the same, and even the same leaves and plants will show subtle features when carefully compared.

These are all phenomena that manifest the uniqueness of living beings.

However, when one point of view is proposed, there must be another opposing point of view.

The birth of the mirror image made it possible for human beings to visualize their own appearance.

So, every time you see yourself in the mirror, will anyone think that maybe in another time and space, will there be a different self?

It sounds like a very crazy idea, and I guess few people think about it, but scientists have such a theory, that is, the parallel space-time theory, also known as the multiverse theory.

Just imagine, in a parallel time and space, is there really another self?

This argument is often used to show that the subsequent development of a different course of events or a different decision exists in different parallel universes.

Infinite universes, each parallel to each other on its own timeline.

The matter and laws of physics are the same in every universe, but the occurrence of events is not the same.

You can use the analogy of a treemap, when the time and space progress to a causal event fulcrum, there will be several bifurcation branches, leading to different event outcomes.

In the parallel universe theory, there are infinitely many fulcrums and bifurcations, so there are infinite timelines, and there are infinitely many different universes in progress.

Just like the relationship between a tree and its branches, different branches are equivalent to different time and space, and their natural direction is different.

This theory is also often used to explain other refutations, such as the one about time, that "a ball falls into a time tunnel, goes back in time and crashes into itself, thus making it impossible to enter the time tunnel".

To solve this refutation, in addition to assuming that time travel is impossible, it can also be explained by parallel universes.

According to the parallel universe theory, the ball crashes into itself, and it doesn't, in two different parallel universes.

With the in-depth study of quantum mechanics, the theory of parallel space-time has been continuously proposed, debated and demonstrated by scholars in various fields.

Parallel space-time refers to other dimensions that are separated from a certain space-time and exist parallel to the original world, which are both similar and different.

In these dimensions, there are also planes that were born under the same conditions as the current Earth dimension, and there may be planets that are the same as the planets inhabited by humans, or planets with the same history, and there may be people who are exactly the same as humans.

At the same time, in these different dimensions, things will have different outcomes: species that are extinct in one time and space may be evolving and growing in another.

Having said all this, it is just to avoid river crabs and lead to a time and space that is close to our world but not the same.

In a parallel space of refutation, the same civilization evolves, but like "Schrödinger's cat", inside and outside the box, completely different, and the whole world is divided into two versions of itself.

Like the earth, there are mobile phones, cars, skyscrapers, computers and the Internet, railways and sea and air routes throughout the territory, and there are also yellow, white and black skin colors.

However, the civilized world here is no longer composed of many countries in their own countries, but has been unified into a whole "Union" of states, collectively known as the Azure Federation.

This planet is called the Azure Star.

As the crust of the Azure star moves, the continents above the Azure star gradually converge in one direction, and although there are still seas between some areas, the distance has been much closer.

In order to facilitate the distinction, the Teal Federation divides the world into twelve continents, and people of all colors live together and blend with each other.

With the development of the world, Chinese, English, French, German and other Chinese languages on the earth have evolved into the dialects of the continent on the blue star, and as for the unified language, it is an ancient language called Yayu.

Of course, the blending of cultures has not erased the legends of different regions.

For example, mythological stories such as Norse and Greek also exist.

And what is even more absurd is that here, the unreliable creator has even rudely blended the modern city with the bizarre world, and many things that are not like reality are not distant ancient legends for the inhabitants of this world.

There are two flowers, one on each branch.

That's where our story comes from.
