Do people really have a past and present life, and can they travel through the past and future?

Well, but according to Hawking's doctrine in the black hole, crossing can be established. As long as you reach the speed of light, you can reach through a black hole through an accelerator, is there another article that you are reading that is exactly the same as this one? That guy isn't you, but lives on a planet called "Earth" with mist-shrouded mountains, endless fields, noisy cities, and 7 other planets revolving around a star?

His or her life experience is the same as yours every second. However, maybe she's about to put down the article at the moment, and you're going to read it.

The idea of this "doppelganger" sounds strange and implausible, but it seems that we have to accept it because it has been supported by the results of various astronomical observations. The most popular and simplest model of the universe today states that there is a galaxy about 10 (10 28) meters away that is exactly like our Milky Way, and there is an identical you in it. Although this distance is beyond people's imagination, it does not affect the reality of your "doppelganger" existence.

The idea originated from a simple "natural possibility" rather than the assumption of modern physics: that the universe is infinitely large in size (or at least large enough) and is evenly distributed with matter, as astronomical observations have suggested. That being the case, it can be concluded according to the laws of statistics that all events, no matter how similar or identical, occur an infinite number of times:

There will be an infinite number of planets that will give birth to human beings, and among them there will be people who look exactly like you, who will look exactly like you, who will have the same names, whose memories and even the same actions, and choices that will be exactly the same as yours, and there will be more than one such person, to be exact, an infinite number of them.

Recent cosmological observations show that the concept of parallel universes is not a metaphor. Space seems infinite. If that were the case, everything that could have happened would have happened, no matter how ridiculous it might have been.

Far beyond the reach of our astronomical observations, there is a universe that is exactly like ours. Astronomers have even calculated their average distance from Earth.

You will probably never see your shadows. The farthest distance you can observe is the farthest distance that light has traveled since the Great **: about 14 billion light years, or 4x10 26 meters, which defines the size of our observable horizon, or simply put, the size of the universe, also known as the Hubble volume.

In the same way, the other universe you live in is a sphere of the same size. The above is the most intuitive explanation of "parallel universe". Each universe is a small part of the larger "multiverse".

A parallel world.

Eventually, you will travel to a world similar to that of an ancient dynasty.

The more you say.

I firmly believe that it is possible!
