According to the multiverse theory, our universe is just one of many other universes. Just think of Doctor Strange, it's not bad in terms of representation, if we can't imagine what the multiverse could be like, of course it's a slightly watered down version.
Maybe we are just a slice of the infinite universes we call the multiverse. Maybe these universes appeared after the Big Bang, or they may be hidden in extra dimensions, or they may have formed when a quantum property transforms from possible states into a single reality.
Many worlds are reflected
The multiverse hypothesis appeared in science 40 years ago, when it was discovered cosmic inflation belief This explains the exponential expansion of space. This explained how multiple universes could exist and claimed that after the Big Bang, the universe inflated and expanded like a balloon. The theory of cosmic inflation also sheds light on the nature of the universe and the multiplicity of independent bubble universes that could exist. But it also demonstrated that matter is evenly distributed throughout the universe, and why space is not curved on the largest scales we observe.
The shape and history of the universe depend on this curvature.
If the density is greater than a certain critical value, the universe is curved like a sphere and may collapse. On the other hand, if it is less than the critical value, it is negatively curved, starting out like a saddle, but spreading out faster.
Many cosmologists have recently turned to cyclic universe theories, which hold that the universe moves in a never-ending cycle between inflation and contraction. These theories contemplate multiple universes existing at different times.
Neil Turok, Physicist at the University of Edinburgh researchDevoting his excavations to the multiverse, a few years ago he proposed, with Latham Boyle, who works at the Perimeter Institute, an alternative to cosmic inflation that could explain the evolution of the early universe. This became the mirror universe.Which extends back in time since the Big Bang.
According to them, the mirror universe explains all the things inflation can do, but also other mysteries, such as the enigma of dark matter and dark energy. In their imagination, it is a geometrically symmetric universe, like an hourglass, with one side showing the universe flowing forward in time, and the other half showing the universe flowing backward in time. In the middle is a singularity, where the wavelength of radiation in the universe would be smaller than the small Planck length, about 10 to 20 times the diameter of a proton.
the It's a mirror image. Unlike the JKSimmons series, we cannot reach the other side.
According to Turok, the theory will be tested in the near future using instruments from the Euclid satellite and the Vera C. Rubin Observatory. If the analyses are successful and the theory is confirmed, it could be the most convincing theory of dark matter.
Are we really?
By the way, the mirror universe theory could also solve another problem with the big bang theory:
Do we even exist?
According to this theory, there should have been as much matter as antimatter at the beginning of the universe. When they collided, they destroyed each other. But why is the universe full of matter? And where did the antimatter go? However, if there is a mirror universe running in the opposite direction, then the question of where the antimatter went is solved: to a companion universe running in the opposite direction to ours.
Boyle and Turok found that their new approach allowed them to calculate the gravitational entropy of the universe, understand the curvature of space, the cosmological constant, and the total entropy of radiation. As evidence, they examined the cosmic microwave background radiation, the leftover light from the Big Bang. This could help you find alternate universes. As long as the theory is proven, it remains Dr. Strange And the It's a mirror image..
