while Parallel universes are the main element in science fictionThere are some real scientific theories to support them. But if the parallel universes exist, can we travel to them? Certainly it will not be easy, but let’s explore this possibility.
The parallel universes are in two places in material theories. One in our perception Economic inflationThe theory of the very early universe. In those turbulent times, many universes may have swamped once (and continued) and branched into a huge number of individual universes, each of which has its own types of physics and material arrangements. But traveling to other universes will not be easy, because it exceeds our noticeable horizon and move faster than Light speed. It would take many of the frequent miles of the traveler.
Other capabilities Multiple universe It is in many worlds interpretation of quantum mechanics. This interpretation says that when a random amount occurs, the “universe” gets one of the possible results, while other universes get others. Thus, the multiple universe is constantly filled with all possible possibility.
But how can we reach one of those parallel universes?
The trick is to build a time machine. It doesn’t matter how you do that; You just need to return in time. Usually, return in time offers all kinds of bad paradoxes, such as fame GrandfatherOr, less violent, inconsistent history. Try to return in time and destroy your time machine. Now it does not exist, which means that you cannot return in time to destroy it, which means that it should be present.

maybe Traveling through time In the past, these reasons are exactly prohibited, according to guessing the protection of the timeline Stephen Hawking. Or perhaps travel through time to the past, but with one strict base: you cannot change the past. This is known as Igor Novakov’s self -associates. But how can you go to the past without changing it?
One of the possible answer is that when you travel to the past, you do not go to your past. Instead, it slides to another date. If you go back in time and kill Hitler, you do not kill Hitler your past; You kill someone else. In this alternative universe, Hitler was always killed by a killer who travels through time from another world. When you return to the future, you return home, with the past that has not changed.
The interpretation of many of the world provides a natural platform for creating this alternative history. If the universe is divided and constantly branched anyway, then traveling through time simply takes you from one of those branches to another. Or, at another possibility, when you come back in time, you create a new branch that was not before.
Although all of this looks elegant and tidy, it is going through the slight complications that no one has done at all. We do not know how this process actually reveals or through the mechanism that shows alternative history.
Attempts to move in the problem by studying quantum mechanics have achieved mixed results. I left for their own devices, the quantum fields tend to go to the corners when time for time. You can stabilize it – if you abandon some basic principles of theory, such as the principle of correspondence or monotheism, which says that quantum processes ultimately lead to sample behavior and that basic reactions are vice versa. No one is really ready to give up these, because they look essential for the theory – so we are stuck in that front.
Besides, even classic irony systems face problems. Suppose you have a key that can run your time device and stop it – for example, by opening or closing Worm. We do not know how the alternative history can accommodate changes in its chronological structures such as such, regardless of any quantity that occurs at an atomic level.
However, if we can create a time machine, we can easily test if an alternative date is created. All we have to do is change something in the past. If you are not allowed to do this (for example, regardless of how difficult you try, you cannot kill Hitler), you know that there is only one time schedule with a past closed in stone. But if you accomplish the task, you know that alternative dates are real and that the interpretation of the numerous worlds of quantum mechanics may be valid.
We don’t know if any of this is possible. On the other hand, we cannot exclude it exactly. It seems that travel through time to the past is forbidden, but for reasons we cannot distinguish easily. It seems that our past has disappeared forever – but it is also possible to be just one branch of many and that visiting alternative universes is easy as … well, it is not easy at all.
