Although parallel universes are an element of science fiction, there are some scientific theories capable of sustaining them. But what if the parallel universes really exist? Could we travel to them?
It will certainly not be easy, but proposed to explore this possibility, in an article published last week, which combines Quantum Physics and Philosophy.
Parallel universes appear in two sites in physical theories, begins by explaining the magazine.
One of them is ours extremely primitive universe theory. In those tumultuous times, many universes may have been inflated at once (and continued to inflate) and branched into a huge number of individual universes, each with its own types of physics and provisions of matter. But traveling to other universes would not be easy, because they are far beyond our observable horizon and move faster than the speed of light.
The other multiverse potential is the interpretation of many worlds of quantum mechanics. This interpretation says that when a random quantum process occurs, a “universe” obtains one of the possible results, while other universes obtain others. Like this, the multiverse is constantly being filled with all possible quantum possibilities.
“But how would we come to one of these parallel universes?” He asks.
The trick is to build a time machine
However, back in time introduces all kinds of unpleasant paradoxes, such as infamous.
Attempts to solve this dilemma through the study of quantum mechanics have had mixed results. If they are left to their luck, the quantum fields tend to lose control when time machines are involved. Also, even classic and non-quantum systems are faced with problems.
Let’s say we have a switch that can turn on and off the time machine. We do not know how alternative stories can accommodate changes in their space-time structures, regardless of any quantum processes that are happening at a subatomic level.
However, if we could build a time machine, we could easily test if alternative stories are created. All we would have to do would be to change something in the past we remember.
If we are not allowed to do so, we know that there is only one timeline with a past that is recorded in the stone. But if we fulfill the mission, we know that the alternative stories are real and that the interpretation of many worlds of quantum mechanics can be valid.
As Space.com writes, we don’t know if none of this is possible. And so we cannot exactly exclude it. Time trips to the past seem prohibited, but for reasons that we cannot easily discern.
“Our past seems to have disappeared forever – but it is also possible that it is just a branch of many and visiting alternative universes is as easy as… Well, it doesn’t look easy“It concludes Space.com.
