Hey👋 spacegeeks ....
Dr.strange mmm well an epic sci-fi movie and the Buzz is about the 'multiverse' and other dimensions alright now,we are now gonna leave the parallel dimensions aside.now what is a 'multiverse'....think about it many of us may have heard about the universe cause we all have come across it in highschool..or some other study..now coming to the 'multiverse' a 'multiverse' (meta-universe)is also called a 'meta -universe' which is the hypothetical set of finite and infinite possible universes, including the universe in which we live. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, and the physical laws and constants that describe them.(the physical laws of our universe will not be applicable to other universes)
And the universes between the 'multiverse'is called 'parallel universe'
The graphical representation of the 'multiverse'
And now who described this whole 'multiverse'thing sure not dr.strange😂😂,well it was described by Erwin Schrödinger In Dublin in 1952, and it was based on his noble equations
Explanation:
The structure of the multiverse, the nature of each universe within it, and the relationships among these universes differ from one multiverse hypothesis to another.
And the term'multiverse' is used particularly in 'science fiction'and 'fantasy' many physicists believes in 'multiverse'
Some have argued that the multiverse is a philosophical rather than a scientific hypothesis because it cannot be falsified. The ability to disprove a theory by means of scientific experiment has always been part of the accepted scientific method.Paul Steinhardt has famously argued that no experiment can rule out a theory if the theory provides for all possible outcomes.
In 2007 a physicist named laureate Steven Weinberg stated that if the multiverse existed, "the hope of finding a rational explanation for the precise values of quark masses and other constants of the standard model that we observe in our Big Bang is doomed, for their values would be an accident of the particular part of the multiverse in which we live."well that's so hypothetic😑😑.
Evidence:
So do we have an evidence to prove the existence of these whole 'multiverse'thing well yes in around 2010 a scientist named Stephen M. Feeney he analyzed the data from the Wilkinson Microwave Anisotropy Probe (WMAP) he claimed to find evidence suggesting that our universe may have been collided with other (parallel) universes in the distant past.However, and it was taken away by a more thorough analysis of data from the WMAP and from the Planck satellite, which has a resolution 3 times higher than WMAP, did not reveal any statistically significant evidence of such a bubble universe collision.In addition, there was no evidence of any gravitational pull of other universes on ours😯.and even the brightest mind of 21st century Stephen Hawking also stated about it.
Classification of these 'multiverse' theories
A scientist named Max Tegmark has provided a taxonomy of universes beyond the familiar observable universe. And they are the four levels of Tegmark's classification and are arranged such that subsequent levels can be understood to encompass and expand upon previous levels.
The levels are
- Level I: An extension of our Universe
- Level II: Universes with different physical constants
- Level III: Many-worlds interpretation of quantum mechanics(oh! Man that's a lot of data to handle I'm just 17 phew quantum mechanics)
- Level IV: Ultimate ensemble
And there are other theories like
- Brian Greene's nine types
- Black-hole cosmology
- Anthropic principle
- Occam's Razor
- modern realism
Arguments against those theories
The below lines are from The new York times, by the author of a brief history of 'multiverse' named Paul Davis
For a start, how is the existence of the other universes to be tested? To be sure, all cosmologists accept that there are some regions of the universe that lie beyond the reach of our telescopes, but somewhere on the slippery slope between that and the idea that there are an infinite number of universes, credibility reaches a limit. As one slips down that slope, more and more must be accepted on faith, and less and less is open to scientific verification. Extreme multiverse explanations are therefore reminiscent of theological discussions. Indeed, invoking an infinity of unseen universes to explain the unusual features of the one we do see is just as ad hoc as invoking an unseen Creator. The multiverse theory may be dressed up in scientific language, but in essence it requires the same leap of faith.
— Paul Davies, A Brief History of the Multiverse
I personally think that we may be living in a 'multiverse' that would be so cool cause we won't be we would be infinite.
And sorry for not giving any mathematical equations cause I don't know math my brain cannot process math😊
