Parallel universe is a concept that often appears in science fiction works, but as scientists explore the universe, more and more scientists are beginning to support the concept of parallel universe.
Parallel universe, also known as multiverse theory, originated from quantum mechanics. Quantum mechanics believes that a thing can be in two states at the same time, a particle can be in two places at the same time, and a cat in a box can be alive and dead at the same time. Since things can be in multiple states at the same time and have infinite possibilities, the development of the universe may also have different branches, thus forming parallel universes.
Parallel universes in science fiction are universes with different timelines; parallel universes in physics tend to be based on different probabilities of quantum mechanics, creating multiple universes with different times and different physical laws. . What does a parallel universe look like?
When it comes to parallel universes, many people will think of independent spherical universes distributed in unknown spaces outside the universe. Different parallel universes are relatively independent.
This is currently the most accepted parallel universe model. It is like galaxies in the universe. Each galaxy is relatively independent and distributed in the universe. Different galaxies have different celestial bodies and different parallel universes. There are also different worlds in the universe.
However, the parallel universe model of the spherical universe first assumes that the universe is spherical, but the shape of the universe is still in the exploratory stage, and according to current scientific detection data, the curvature of the universe is flat. This means This means that the universe may be an infinite open space, or a spatial geometry with planes.
Therefore, scientists have also proposed a new parallel universe model-nested parallel universe. Different parallel universes are nested within each other to form more complex shapes, even irregular shapes. Parallel universes with higher spatial dimensions are located in the central area of ??the nested model, and parallel universes with lower spatial dimensions are located outside the nested model. Is there another self in a parallel universe?
The most common theory of parallel universe is another self in the parallel universe. With countless parallel universes, there are countless possibilities. This is actually a matter of probability.
In the theory of quantum mechanics, microscopic particles can exist in two places at the same time. Within the possible range, particles may appear randomly anywhere. Therefore, from a probability perspective, parallel universes have the possibility of repetition. If there are enough parallel universes, the same things as other universes may appear.
But with the advancement of physical theory, many physicists have put forward new views on the physical laws of parallel universes.
Basic physical theories such as quantum mechanics and relativity may only apply to our universe, while other parallel universes are likely to follow completely different physical laws and even have different physical concepts.
In our universe, time moves forward forever and cannot be stopped, and mass produces universal gravity. But in other parallel universes, time may flow backwards, and mass may cause repulsion. This is entirely possible in different parallel universes.
Multidimensional space theory and parallel universe theory can help physicists solve many cosmic problems.
For example, antimatter is extremely rare in the universe. Antimatter and positive matter have different charges. Theoretically, the universe should be in a state of charge conservation, and there should be as much antimatter as positive matter. However, scientists have not found a large amount of it in the universe. Antimatter discovered.
Perhaps at the beginning of the birth of the universe, these antimatters reorganized the "antimatter universe" due to special forces, which is also a member of the parallel universe. Summary:
The theory of parallel universes is not a completely science fiction theory. With the development of physics, more and more scientists are beginning to support the multiverse theory of parallel universes.
However, the space in the universe that humans can currently explore is too small. Perhaps when humans truly discover the "boundary" of the universe, they will be able to directly see the magnificent scenery outside the universe!
