I find the storylines in movies to be intriguing, but in reality I don't believe they exist for the simple reason that a parallel universe would have to be a construction, which would imply that an all-powerful being (at least in our eyes) would have to be responsible.
I strongly disbelieve that an all powerful being, even if it existed, could give a crap about us.
I mean, look at us. We are the trailer park planet of the galaxy - our planet is even surrounded by floating garbage. We're drowning in our own pollution and toxic chemicals and are slowly, yet decisively destroying the very environment that provides us with life support and sustenance. Any existing god would have intervened at this point, and none have, so this isn't going to magically fix itself.
No, I don't. I understand that they came up with the idea to explain the slit experiment, and it does neatly explain it. But it has other problems that are starting to mount. Physicists are slowly starting to abandon this as a viable explanation
I'm happy to except other universes but not the popular idea of them being identical bar a small change. Today I sprinkled 56 grains of salt on my dinner, does that mean in another universe the only difference was 57 grains in fact everything from 0 to a silly big number of grains. Then if you take everyone else on the planet putting salt on their dinner you have a stupid number of mathematical combinations and thats even before you add the pepper.
That's indeed true Poppy. But I doubt the ONLY difference would be in the number of grams of salt within any specific universe; other possibilities could also have been taken into effect before or after the pouring of the salt.
Every single possiblity that can occur within an enclosed Quantum Mechanical System is called that system's Wave Function, and this corresponds to different energy levels which translates into different outcomes at the Macro scale. When we observe matter, according to the Copenhagen Interpretation, we force its Wave Function to collapse from Its state of decoherent superposition. Said decoherent superposition is the state of every single energy level within that Quantum Mechanical System existing at the same time. So it can be said that as long as we don't observe this system, every single possiblity and outcome is occuring at the same time, it isn't until we observe it, that we force it to choose one state and outcome, which is entirely at random. This is what Einstein didn't like about Quantum Mechanics; you can never predict with certainty what the outcome will be, but only predict the chances of it occuring.
So according to the Copenhagen Interpretation, once we force that system to choose only one state of energy at random by observing it, that state translates into an outcome in the real world. The other possibilities disappear and don't ever have a chance of happening again within that strict frame of time. The Many-Worlds Interpretation denies that Wave Function Collapse ever occurs and that observing matter causes one of the possibilities to occur in this Universe, but that the others still occur within this strict frame of time in Parallel Universes less than a millimeter away from our noses in a process known as Instantaneous Decohesion. These Parallel Universes occupy the same coordinates that we do, but exist in separate planes of time separated, according to M-Theory, by the 5th dimension. As 3 dimensional creatures, we can only feel the effects of the 4th dimension (time) as we age and we're completely unaware of the other choices we could have taken or could have occurred in the 5th dimension.
A thought experiment to put this into perspective is called Schrödinger's Cat. Imagine a Cat within inside a non-transparent box, so you can't see inside of it. Along with the cat, is an unstable radioactive material and a Geiger Counter hooked up to a device which will release poisonous gas if it defects radioactive decay, killing the cat. Let's say that every minute that passes there's a 50% chance that the material will decay, killing the cat by poisonous gas. Since there's no way for us to know the outcome because the box is not transparent, it can be said that after 10 minutes have passed, the cat is both dead and alive at the same time. It isn't until we open the box that we see that the cat is either dead or alive.
So the Wave Function here would be 2: either dead or alive. The Decoherent Superposition is in effect as long as we don't open box; both states of energy are occuring at the same time. When we open the box we collapse the Wave Function, forcing the system to choose one of the states at random; therefore seeing the cat as either dead or alive. This is for the Copenhagen Interpretation, formulated by Niels Bohr. In the Many World's Interpretation, formulated by Hugh Everett III, Wave Function doesn't collapse and instead Instantaneous Decohesion does. So we can say that if the Cat survives all 10 minutes once we open we box, the Cat died 10 times in 10 separate Parallel Universes right next in door in the same frame of time and at the same physical coordinates. This is the Basis for the Quantum Suicide and Immortality thought experiments. These experiments take place from the perspective of the Cat inside the box and is meant to distinguish the Copenhagen Interpretation from the Many-Worlds Interpretation of Quantum Mechanics, but with the cat replaced with a suicidal human and the Geiger Counter hooked to a gun instead of poisonous gas.
But what is the source of all this Wave Function and Decohesion mumbo jumbo? It originates from an actual experiment known as the Double Slit Experiment; the grandfather of all Quantum weirdness!
It's scary to think that out there there's a poppy who's pure and chaste. I like to think of it as a big bag of mixed coins. You can lay them out in any order or pattern in large number of combinations but since the initial number is fixed you eventually repeat a previous pattern. If we replace coins with atoms the same logic applies. Furthermore given enough atoms all other possible combinations become possible including sister poppy living in a convent, dragons. Fairies, trolls, God, shit I've just proved God's existence...
YES. My ex once told me that my parallel self is doing the exact opposite of everything I do at every moment and I always think about that lol it’s cool to me. It’s just hard to believe that we are the only ones out there in this whole frickin solar system, why couldn’t there be a parallel universe?
I think parallel universes might exist. Our universe exists, so why can't others? Given enough universes (very important assumption), some are bound to develop in the same way for a while until a quantum event gives a different outcome for one than the other. Assuming free will and choice exist, which is an entire discussion itself, each choice is another event which can cause two previously identical universes to differ. Differences caused by quantum events don't need to be large or noticeable at all, but choices stack up to make slightly bigger differences in the world as a whole, as it's a pretty chaotic system.
Unfortunately, people need to be well versed in Hugh Everett's Many-Worlds Interpretation of Quantum Mechanics and be able to distinguish it from the Copenhagen Interpretation, understand the theorized closed-loop structure of the Graviton at the hypothesized String scale, know about the Wave-Particle duality of Matter and definitely be aware of the implications of the Double Slit Experiment, understand Wave Function Collapse, Superposition, and Instantaneous Decoherence Principles, know about Quantum Tunneling and Entanglement, the Heisenberg Uncertainty Principle, Quantum Suicide and Immortality, Schrodinger's Cat, Hilbert Space, M-Theory, Calabi-Yau Manifolds, and a whole host of other nerdy words and concepts in order to properly answer this question. So expect poor answers from people here.
The concept it meaningless in that a truly “parallel” universe would be inaccessible from our universe and thus its existence would be impossible to prove or disprove. If you mean a sort of alternate reality that could be accessed or measured from ours, the jury on that is to some extent still out to the extent that the question of whether its possible to “cut and paste” spacetime (in math-speak, modifying topological constants) is not settled by current theory. Otherwise, the connection between universes would have had to have existed from the Big Bang, and there are a lot of reasons to believe that would be impossible.
Nope. I think this has the same problem to time travel theory. Where basically no matter what we cannot time travel into the past cause if we could in the future we would of come back already. Same for Parallels since in theory one should figure out they exist and create a way to get to others. Kinda like rick and morty how the other version of him came to tell him about the portal gun. If it exists there is no reason why we haven't seen proof of travel between them Unless if there is no way to do so but then pointless to think about it.
Maybe time traveling and inter universe travelling is not accessible to public at large. How will we get proof when only a handful among millions are entitled to this? There are some rumors about mysterious people and events, probably tall tales,
I mean tbh you could say that about anything. Like what if we have proof of god but only handful people know this. So anything can really apply to that which is why i would just ignore that as an option for a basis of a theory. Could be right but i ain't gonna go back on all the info i have known to me or the general public just cause someone could be hiding something. Unless if there is enough evidence to show they are which there really isn't so right now.
I believe it is possible for there to be other worlds with life like Earth. However, I do not believe there is another me out there. Just one different decision, change of look, circumstance or even a minor change makes the other version of "me" a different person. Also, the Bible does not expand on anything outside of Heaven, Earth and Hell so it is completely possible for there to be life outside the Earth. The Bible's only focus is to instruct humans how we should be while on Earth and how that affects whether we go to Heaven or Hell.
I can’t say whether I do or do not believe that a multiverse exists because there is currently no definite proof of the multiverse existing. But the multiverse theory hasn’t been “debunked” either.
But ever since I watched the web series “man in the high castle” I’ve become intrigued by the multiverse theory where a vast array of worlds just like ours exist side by side. In each world things are different.
In our world the axis powers lost WWII, in another world the axis powers won WWII.
In our world the Soviet Union lost the Cold War, in another world the Soviet Union won the Cold War
If the multiverse exists, perhaps we are not meant to access it because each world had it’s own destinies/prophecies and opening a doorway to the multiverse can cause catastrophe by allowing unwanted visitors from the multiverse entering our world.

It's an interesting topic in SciFi. I find it possible that universes are like 'bubbles' floating in a sort of 'extended' or 'widened' universe - with no option for contacts between each other. A (naturally) next to identical 'copy' of me (or us) is absolutely unlikely to me; unless we are sort of part of a computer simulation. But those other 'me's' would not be me. (see: https://en.wikipedia.org/wiki/Simulacron-3 )
yes because i also believe in a timeline because i believe in the possibility of time travel so i believe that parallel universes is just our earth with different time lines, for example, i believe its the same life as me but with another timeline, so right now im broke and jobless, i believe if i wouldve stayed in school i couldve succeeded quicker so i stayed in school in that universe so i live a different life then i do in this universe, i hope you know what i mean, i might just sound crazy ha
No. It is a "shot in the dark" by "scientists" as a rationale for explaining how this planet is perfectly suited for sentient life AND to get past the otherwise insurmountable problems of repeated examples of irreducible complexity in organisms. The idea is that given infinite opportunities of course we would have a perfectly suitable planet that also has the perfectly timed simultaneous changes required to jump those hurdles. In truth it is an attempt to get around the "God" idea, and while it cannot explain the existence of space-time-matter-energy, it is far better than the other attempts. Those other attempts, when analyzed, have less likelihood than hitting a dime that is circling Alpha Centauri with a single shot from a pellet gun fired from the moon in such a way that it ricochets back and strikes the left eye of the Statute of Liberty.
It is a popular theory among physicists. I understand the theory and I know there is "math behind it" but on the other hand, you can put math behind things which clearly have nothing to do with reality. When it comes to the multiple versions of ourselves, there is more than one theory for that. One is that every possible outcome is played out in another universe. For example you could choose vanilla or chocolate ice cream and no matter what you choose, all other options branch off into other realities. Another is that we just live in an endless multiverse where it is inevitable that the exact same formula for you has assembled in another universe but your lives won't necessarily be the same. There is no branching but literally every possibility is guaranteed to exist. Then there is a combination of those two. I'm unconvinced so far but I'm not rejecting it altogether as a possibility.
The trouble with "Parallel Universes" is that it's Narcissistic. So there is another planet Earth and out of all it's chaos, you are on it. So that means everyone had to marry the same person on this planet. But instead of being a welder on this planet, you are an electrician on that planet. It's too far fetched.
Now if you said that on that parallel planet everything is different because things happened differently - then I'm game.
Open to someone going there and coming back with photos! I figure, I'm living in one of the parallel universes right now (1). If there are more, that be cool... not sure what I'd do with it though... go back in time? I can barely use the universe I have now.
If ya think about how large and small everthing is, it quite amazing... lucky to be alive so we can imagine all this stuff...
The other universes represent alternative timelines, and all but one of them are destroyed with each second of passing time as events unfold.
In other words, they exist in the future only. Every time you make a fateful choice, you eliminate all other potential universes except for the one you chose. Every choice made by every person and every random event causes the elimination of an infinite field of potential universes.
Unfortunately, while parallel universes with simular circumstances are interesting... I only subscribe to the theorys stating that some matter within our universe is outside our wavelength, and that we therefore do not interact with it... But, assuming there is an infinite number of alternate universes... Very few of them would contain humans.

No, I dont.
But i also dont understand the maths behind the idea but i suspect that its an error produced by our lack of understanding at this time.
Trouble is that our minds are not built to deal with issues like this, we can't even imagine the sorts of numbers thrown around with national economies so you can pretty much forget about anyone, even the best of us, bending their minds around the idea of infinities.
Well it's a reasonable theory. There are a couple of ideas and theories about this floating around in the physics community. The multiverse theory is interesting. Even the concept of higher dimensions talks about alternate worlds ranging from similar to us to the exact opposite of it, some with even their own different set of physics laws.
It's a fun conjecture. It's suggested fundamental constants might differ from world to world. My question would be if mathematics is an invariant. If it isn't, then this theory would only apply in this universe. In another universe, the same theory need not hold, which would be weird..
