Physics Friday #15 [DWQ]: Multiverse theories
Preamble: What is DWQ?
This is another mini-series that will be ongoing. Similar to opinion posts, there is another type of post that I want to explore.
DWQ - Dealing with Quacks (alternatively, Crackpots or Nuts)
Both crackpots and quacks are unified by what they do. They propose there is something "fundamentally wrong with physics" and that they have this new theory that will change everything.
Their theory is about some fundamental truth with the universe. That the "physics establishment" is constantly attempting to chase ridiculous theories because they don't want to accept reality.
A crackpot is someone who generally has expertise in physics, or a related field like chemistry or engineering. Often they are motivated by a desire for fame.
A quack is someone who has no experience in the field, often with a monetary interest in what they are selling.
"Nuts", which is short for "religious nuts" are those who promote their ideas out of faith and a desire to spread their beliefs. They are more likely to strawman existing ideas first.
I hope that you, the reader, can already understand why I don't like these people. They muddy the waters, mess around with science communication, and give the profession a bad rep. They also lie and pedal disinformation, which ends up acting as a gateway to more serious conspiracy theories within the medical or political realm.
It's also important to identify that this acts on a scale. Technically, some string theorists are a lite form of crackpot - particularly in the way they present their theories and ideas to the public.
But they are significantly more respectable than a flat-earther, or a self-help guru, or a evangelical apologist.
The Multitude of Multiverse theories, or the MultiMultiverse
Multiverse theor(ies) are usually strawmans made by religious fanatics. Think PragerU as a great example.
The argument goes like this:
Scientists have no empirical explanation for fine tuning or the reason for the existence of the universe
In order to explain it, they constructed multiverse theory to explain the source of it
By occam's razor, the simpler argument is the existence of a creator entity, that fine-tuned things for us
Of course you can see how bad the arguments are. The problem is of course that science hasn't accepted any multiverse theory.
Multiverse theories are neat explanations or consequences of other theories, but they are either limited in their explanatory power, or their efficacy to test.
But what are the multiple multiverse theories? Here's three that people claim are multiverse theories:
Many worlds interpretation (a QM thing, and only a multiverse theory in pop culture)
Inflation multiverse theory (one possible consequence of the cosmic inflation hypothesis)
Just an actual multiverse theory (arguable cosmic inflation can lie here)
Many Worlds Interpretation
I've already run through the main gambit of what the Everett interpretation is, so I'm going to tackle this from a pop sci perspective.
When you were younger, you might've heard that the many worlds interpretation literally means many worlds. That with every decision you make, you create a new seperate branching reality. And that multiple realities can simultaneously exist.
Of course, there is an issue with this. Mainly that there aren't multiple realities - there is just one reality, in a superposition of states.
This superposition dictates there is one reality, just that this reality is probabilistic. These realties aren't separated by physical space. It's just one big 'wavefunction'.
Decisions in the many worlds interpretations are also examples of when pop sci goes wrong. It's not necessarily the religious nuts who cause this misconception.
What causes more splits in the wave function is the interactions within it. When an electron collides with a positron, when a chemical in your brain goes from one end to the other. Interaction is what creates these splits.
Technically, decisions are caused by the interactions between electrical signals in our brain, and us making a decision often involves interacting with the world around us. This is how the misconception arises, but the reality is that the split occurs well before and well after a choice is made.
Of course, it's important to state that, the many worlds interpretation is still not the "correct" interpretation. What it posits hasn't been proven.
Inflation Multiverse theory
Inflation theory in itself is already a bit on the rocks in terms of an explanation of why our universe is the way it is. There isn't really any way we can use GR/the standard model to explain why inflation happened. At least, without having to add an extra field or constant in our equations.
Generally, inflation is explained using the addition of a new inflaton field, which in the higher temperatures of the early universe, caused a rapid expansion of spacetime.
This rapid expansion is generated by the field living in a heightened energy state.
At some point, the field reaches a sudden drop-off, at which point the expansion rate suddenly slows down to our expected GR level. The inflaton field then remains at a local minima.
Where does the Multiverse theory come into this?
The drop-off of the inflaton field is not universal. It only occurs at particular points in spacetime. This creates a 'bubble' of space that slowly expands in comparison to the surrounding ocean of space that is rapidly expanding.
We exist in one of these bubbles, which expands at a normal rate. But we aren't the only bubble.
There could be several bubbles surrounding us. All separated by physical space that expands at incredible rates. These bubbles create an effective multiverse.
It's not technically a multiverse because every bubble is still in one single physical universe.
Generally, this version of inflation multiverse theory is better accepted as it has inflation theory to back it up. But it's still not provable, so it's not regarded as truth.
The actual Multiverse theories
There are several multiverse theories. But the key thread linking the other multiverses, is that there is no physical way to traverse the space in-between worlds, and that each universe is seperate in beyond a physical capacity.
I can't go into many different multiverse theories, because the main point is that they're all either bullshit or thought experiments.
One example is the "temporal multiverse theory" which states that time is actually a 3-dimensional quantity, were our multiverses are caused by separations in time.
When you go back in time and alter the past, you end up in an alternate timeline future. This is a common way to interpret most time travel movies or scenarios.
Another is the "10-dimension" theory. There are 3 dimensions of space, 3 dimensions of time, and 3 dimensions of "universe". What is this universe dimension? Well it's effectively supposed to be an altering of the fundamental physical parameters.
The problem is that we don't think that the universe happens to perfectly have three degrees of freedom in it's construction.
The 10th dimension is usually unexplained in this theory.
So what was that fundamentalist strawman about?
There is an idea in physics called "quantum darwinism". This theory basically states that from the many worlds interpretation, there will be one probabilistic reality where human consciousness lives in. And thus that version of reality will be the one we see, as it was fit for human life.
This principle can be extended to various different versions of multiverse theory. That out of the many possible realities, we observe the reality that created the perfect conditions for human life.
This argument, that the universe was predisposed to observation, because it had to circularly, is called the anthropic principle. It can be said that it's an extension of the copernican principle.
And that's it. That's the strawman. Of course, this form of darwinism is not really an actual theory, more a thought experiment.
Conclusion
This post is slightly less long than the other ones but still a lot. Oops! Ruh roh!
Anyways, I hope y'all like this post with a different topic. They will be rarer because I want to take my time tackling these types of posts. Please lmk if you think this post was informative or if you'd like to see more!
Next week will probably be on Baryon Acoustic Oscillations. Follow if you wanna see more!

two things with Miguel's theory I'm not getting and something everybody else has probably already talked about by now but I need to rant about it because this shit is slowly eating away at my brain:
1. this whole theory was created because Miguel started comparing his situation with Miles's, sparking that whole "don't play a role that wasn't meant for you" attitude, but to me there's a huge plot hole in that mindset - Miles never chose to be spiderman
like the entire reason why those dimensions collapsed was because Miguel went out of his way to travel to another dimension and father a child that wasn't his, that's not comparable to Miles because Miles didn't go out of his way to get bit by a radioactive spider from another dimension, the spider got drawn towards him because of Kingpin's collider and he's been dealing with it in the best way he can. Miles became spiderman because of someone else's actions, which means that for his universe, it was fate. He quite literally couldn't have dealt with that in any other way and it bothers me how Miguel is self projecting onto Miles by insinuating that he doesn't deserve to exist, especially when you consider the fact that there isn't some sort of uniform way that a spiderman is supposed to get bitten, they just get bit a deal with the aftermath.
which then leads to my next point...
2. canon events aren't completely linear, they're single incidents that coincidentally happen to every spiderman
from my perspective, canon events aren't these uniform rules that you have to abide by, they're similarities in the multiverse that just so happen to align because they have a common denominator - someone playing the role as spiderman
like it's not a "every spiderman does this exact same action and goes through these exact same movements and watches someone die in the exact same way" type of thing, it's a "every spiderman watches a police chief they have close relations with die" type of thing, which leaves a ton of room for leniency
(honestly, that by itself contradicts Miguel's "you're not meant to be spiderman" thing because Miles has canon events just like everyone else, which means that being spiderman was his fate, but that's not the main point I'm leaning into)
the way a spiderman goes through a canon event doesn't mean as much as the canon event actually happening, a main example being Miles getting bitten by a spider that technically wasn't his, but still becoming spiderman and going through canon events just like everyone else
so that leads me to ask another question: if all of Miles's other canon events happened without fail, then what did Miguel see in Miles that led him into believing that he'd be able to save his dad if he tried to?
because as far as I'm aware, all of the other spidermen at the very least attempted to save their police chiefs and failed at doing so, they didn't sit back and watch them die like Miguel is tryna force Miles to do: so wouldn't Miguel going to Miles's dimension and fighting him have an effect on Miles's canon event? in a similar way that Miles went to Pavitr's dimension and interrupted Pavitr's canon event by saving his police chief for him?
like obviously I don't think Miguel will go out of his way to save Jefferson, but if Jefferson is supposed to die while Miles tries to save him, then wouldn't stopping Miles from trying to save Jefferson have the opposite effect??
and here's an extra third point that I thought of while typing this all out:
3. if Miguel believes that Miles being an anomaly gives him the potential to break out of canon events, then he's blatantly ignoring the large probability that Miles has the potential to save his dad and everyone in his dimension, not just one or the other
because if Miles has the ability of creating a bad outcome then he has the ability of creating a good outcome, one cannot exist without the other so even if we lean into Miguel's theory, we have to heavily rely on his self projection in order for it to make sense
and this isn't even me getting into the possibility that all of the other spiders likely realized Miguel's theory was off way earlier on (they're super geniuses so I hope they did) but didn't argue against Miguel because of the lingering "what if he's right", that one in a million chance. the fear of the unknown kept them from questioning what didn't make sense and that resulted in them throwing Miles under the bus
wit allat bullshit goin on, I'm honestly not that surprised that Hobie openly supported Miles from the start, that "fear what you don't know" mentality is often used by fascist leaning governments to manipulate the mass populous, and Hobie, living in a fascist apocalyptic society, peeped that shit immediately and dipped from HQ after he made sure Miles was okay on his own
so uh...yeah! Miguel is tweaking and mentally unwell, spiderpeople in general aren't that good with friendships, Miles needs to reconsider his friendship tier list and set some boundaries because that "they won't take care of you and accept you the way we do" line Rio said hit him hard, (I feel like that's an allegory towards blackness and the experience black kids go through when venturing out on our own and finding our place in outside spaces so I might do another post on that but idk), but Hobie's pretty chill so I hope him and Miles become best buds in the next movie that'd be really nice
yup, that's it I think, if you have more to add please do so I'm so hyperfixated on this shit it's kinda insane actually-
(I started typing this out at 7AM and used a fuck ton of colors so I hope this is understandable, if I'm completely off base and misunderstood the whole multiverse thing please call me out cause I wanna understand this shit so badly)

Pocket Guide to Intercosmic Travel
So, you've just become aware of the multiverse! Eternity, reality, omnicosm– no matter what you call the largest unit of existence that supersedes mortal notions of time and space, you're going to need to reframe your perspective on it. Here's a handy guide to get you started!
Multiversal Structure
The multiverse is composed of two aspects: universes (aka cosmoses or yggdrasili) and nullspace (aka aether or ginnungagap).
Universes
A natural-born universe, also called a “cosmos” or “yggdrasil,” originates as a single infinite point containing all of the spacetime and mass-energy of its existence in compressed form. This is called a “seed singularity” or just a “seedling”: a singularity of infinite potential. This seedling sprouts infinitely-branching possible spacetimes after initial expansion; any possible split fork moment in probability down to the quantum level creates a new timeline (or “branch”) extending off of the previous one.
Once a universe has grown out its branches all the way to the very end, after entropy has rendered every single worldline into a uniform smear of cold, stable, subatomic matter, gravitational force is absolutely uniform across the entirety of spacetime. This causes the ends of the branches to collapse into new seed singularities and pinch off, drifting free through nullspace until accumulated exposure to the primordial background energy triggers germination through quantum flux. Because time and causality don't apply outside the spacetime of a universe, the reproductive cycles of universes form an infinite chain of reincarnation.
Pseudocosms
A pseudocosm or pseudoverse, colloquially called a “Haven,” is an artificial cosmos created by one or more godlike hyperichal beings. Usually created by heavily altering a harvested seedling, these constructs often defy standard universal structure, existing in stable localized monocausality with deliberately maintained (cyclical) entropy. They exist effectively as sandboxes for the transcendent hyperichals, allowing them to “play god.”
Nullspace
Nullspace, also called the “aether” or “ginnungagap,” is the “space” in which universes exist, though it is impossible to actually conceptualize as a “space” because it doesn't technically exist. Nullspace is both infinite and imaginary, meaning that there is no relative position in it: every cosmos exists both adjacent to and far apart from each other. Nullspace is uniformly suffused with a unique form of energy, called primordial or aethereal energy, which has no carrier particle and contains infinite potential. This infinite raw energy is thought to be the driving force of the quantum vacuum fluctuations in each causal universe, which also serves to trigger singularity expansion in newborn universes.
Intercosmic Travel
When an object native to a cosmos exits its branch without a protective pocket of spacetime, its waveform collapses. An object removed from its original spacetime becomes detached from its native past, future, and alternate instances (its “worldline”), inhabiting a new causal lineage tethered to itself alone. When sapient beings accomplish this (except in the case of hyperichal transcendence), their new causal lineage is often called a “personal timeline” or, more succinctly, “lifeline.” Material beings who are capable of intercosmic travel are called, among other things: “Travellers,” “aethernauts,” or “planeswalkers.” Non-material, transcendent beings who have converted themselves to a causality-free post-cosmic format and, effectively, achieved “godhood” are called hyperichals, or simply “Drifters.”
Hyperichals
Hyperichals are sapient beings who have converted themselves into stable, complex superstring resonance patterns which exist outside the spatiotemporal limits of their cosmos of origin. They have attained final and complete knowledge of physics, and have total mastery over the workings of reality through post-singularity thaumatech. This allows them to not only travel freely across the multiverse, but control the structure of reality itself. It is the most literal form of godhood there is; in fact, most universes with known gods are actually the subjects of hyperichal influence.
Cosmography
The best system yet conceived for cartographing specific instants in a given universe is that of the Cosmos Index in the Gardener's Eternal Archive; available in physical, metaphysical, digital, gravirtual, hyperwave, psychonic, superstring compact resonance, and other formats for convenience. Its method is quite similar to that of the hypothetical Library of Babel: a primary starting point followed by a long string of increasingly specific divergence points in time and space. The end result is that the full address of any point in the multiverse is a large paragraph of absolutely eye-watering numerical gibberish, punctuated by the occasional semicolon. Fortunately, the index includes a spot for a cosmic prime-branch's colloquial names as well, making things easier for all Travellers. This is also useful for including pseudocosms, such as the notorious realm of “Crundle.”
A parallel to this project is the Traveller Index, which functions essentially as a “multiverse phonebook” - it is a compendium of all known beings who are capable of intercosmic travel. Each entry consists of a being’s preferred identity, cosmos and specific instant of origin, and a superstring code –much like a hyperichal consciousness, a “superstring code” is a sub-quantum resonance pattern unique to each individual Traveller’s “lifeline.” There are technically infinite entries in the full Index, but its natural form exists in a superimposed state unbound by time or space. When it is localized for active reference, it can have anywhere from a dozen entries to trillions of entries.

wormholes 1
Theoretically, wormholes are places where the fabric of space-time is thin, so it should be possible to travel through the universe, as evidenced in 'A Wrinkle In Time', where the main characters use what they call "tesseracts" to travel enormous distances through space (and, in later books, time.) It is my belief that these "tesseracts" are small, localized wormholes only one being can use, and are only connected to one universe. However, if someone was able to connect wormholes to another universe, it might be possible to travel between universes in that way.
Let us imagine a wormhole in one universe, and a different wormhole in another universe. By utilizing a universal linking device, otherwise known as a portal linker, one would be able to open a small passage between two universes. Now, let us say that someone, we'll call them B, decided to try to link two wormholes together to create a stable passage between the two universes. They would turn on the portal linker, using the space-time field to power it, and set off a seeking system, programming it to search for wormholes inhabiting areas of the multiversal fabric of reality that are close to each other.
Now that B has located the two wormholes, they should cast the two points the portal linker will use to create a passage between universes. The points should be fixed to each of the wormholes, and then B would turn on the portal linker, which would open a small passage between the two universes through the wormholes. If all goes well, the portal linker's passage should adhere itself to the wormholes, which would theoretically make a permanent passage between two universes by way of the wormholes. Unless something causes the wormholes to become unstable and collapse, the passage should remain open indefinitely.

Very busy this weekend but I just wanted to pop in because I thought about it and I wanted to share a thing. I've always liked time travel. Everyone hates it, but I think it's fascinating. The trick with time travel is that it's kind of like magic: The rules are whatever the writer says they are, and that's it. That's all there is to it.
But what's fun with time travel is that writers often don't think of every single possible loophole or contingency or unintended ramification and so a lot of stuff winds up getting conceived that was never meant to exist in the story.
That brings me to my personal favorite piece of accidental time travel metaphysics: The Time Bastard Phenomenon.
What is Time Bastard? Well, it's something that doesn't happen quite so often anymore since modern writers are fascinated by Multiverse Theory. Time Bastard is actually one of many things that Multiverse Theory solves by being a story's working time model. Multiverse Theory has its own problems but at least it gets rid of all those Bastards running around!
Time Bastard is a consequence of linear time travel, one timeline no branches, existing alongside malleable history where the traveler is capable of changing the past. It's not actually something travelers do, so much as a byproduct of time traveling under this system. It's the process by which the traveler or Bastard murders themselves by traveling.
Consider Marty McFly of Back to the Future. Yeah, I know, that movie's pretty much an oldie now. I'M OLD. DEAL WITH IT. In the movie, Marty travels to the 60's and nearly causes his own birth to be unmade. He saves himself by getting his parents together. But in doing so, he changes the course of history.
When Marty returns to the present, he finds nothing the same as he left it. His family's successful now. The school bully works for his dad, who's no longer meek and helpless. And Marty has that cool truck he always wanted.
That's great for him. But what happened to the Other Marty? The Marty that was born into this timeline? The one that grew up with all of this being normal for him. The one that the new version of his parents knew. Where did he go?
Well. The answer is that he went into the past. He went to the 60's following Doc Brown's experiment. We know because when Marty returns to the present, that's still the same. Brown still gets assassinated, and Other Marty still escapes into the past. He just. Doesn't seem to have ever arrived.
He's gone. Wiped from existence by our Marty's act of time travel, the very act of time travel that made him. This is what I mean by a byproduct of linear time travel coexisting with malleable history. Because the story does not operate on Multiverse Theory, the Other Marty is simply.... Nothing.
He jumped in the DeLorean, gunned it into the past, and then he ceased to exist. Erased from his own body and replaced by the Time Bastard Marty, who arrived in the 60's with a completely different set of memories, orphaned from a timeline that no longer exists.
...
So, do you see why people love the Multiverse model so much instead? XD

What’s the Multiverse Theory? Does it connect specific fandoms or is it something different? I like to think that we’re connected to the fandom verses but IDK
Ooh excellent question, fellow internet traveler... The Multiverse Theory (or more or less, the version that I'm a fan of) is a theory our universe isn't the only one, and there are multiple universes parallel to each other, and these universes are presumed to comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them.
Like in Arrowverse (Arrow/The Flash/Supergirl/Legends of Tomorrow/Superman and Lois) they have multiple parallel realities, an example being Cisco and Caitlin from Earth-2 being "evil" meta humans. And like in Dr. Strange Multiverse of Madness where they travel throughout the multiverse to keep America Chavez away from Wanda. And how they end up on Earth-838 are apprehended and brought before the Illuminati, a group consisting of Mordo, Peggy Carter, Blackagar Boltagon, Maria Rambeau, Reed Richards, and Charles Xavier. And Wanda dreamwalks there and... Y'know, carnage ensues.
Supernatural also dives into the Multiverse concept a few times!
I really hope I explained this well enough for you 😃 (I'm sorry if this doesn't make sense, sometimes I can't really say what I mean.)

Y/n: So, if you're telling me that our dreams are like windows from which we observe the multiverse, and I am able to make premonitory dreams, that are dreams which then come true, does it mean that when I have that specific dream, I automatically teleport into that universe?

one of my ADHD life hacks is The Universe Splitter. Sometimes when I have decision fatigue, or feel stuck on an activity and unable to choose to do something else, I can circumvent it by selecting two options and letting a high-tech physics device tell me which universe I'm in.
A few weeks ago I was having trouble sleeping. (because I was camping in Wyoming, in the area with the highest number of grizzly bears in the lower 48. And my sister, who was living and sleeping inside the high-voltage electric bear fence, kept telling me about a griz who ate people in Banff. And how her neighbor got bluff charged awhile ago. And about a mule that stomped a grizzly off a teen boy and saved him. Right before I went outside of the bear fence to camp every single night!) So I put "keep reading" and "go to sleep" into the Universe Splitter app and...it didn't work because there was no cell service to reach the quantum device in Switzerland.
BUT. I have so powerfully conditioned myself to do what the Universe Splitter says, that I thought to myself "there is a universe where I go to sleep and it's this one," and fell asleep almost immediately
This app is more powerful than my concern about being eaten by a grizzly bear.

Some of y'all have it wrong when it comes to shifting
Tumblr media
So you might have been told that the method doesn't make you shift well I'm going to tell you that it does actually that’s all a method will ever do. When they say that a method isn't important on whether or not, you make it to your DR is 100% true let me explain 
Tumblr media
Now, if the method got us to our DRs we all would’ve shifted by now, so what makes us shift? How do we get to our DRs?  I want you to start thinking of your method as a jump now anyone can jump you can’t really do it wrong but the thing is if you jump to somewhere and that somewhere is far away then you’re not gonna make it and you can’t be disappointed when you don’t make it. now I don’t want you to think of your DR as far away but more as the connection is weak we’ve heard that before that connection to your DR is important, but I don’t think we stress enough compared to methods. Now your DR isn’t far but more that there is a gap in order to close that gap you need to be connected to your DR and once that gap is closed, when you jump you’ll actually make it. Now you’ve probably heard how to connect to your DRs write a letter to your dear self consume media of the place you’re shifting to make a Pinterest board write a the script, but I’m going, to be honest those won’t help you as fast now they may motivate you, but there’s an easier way to close the gap. I want you to write three things down that your dear self does daily they don't have to be big they can be simple and then I want you to do those three things, so that when you’re doing them, your DR self is doing them I think you might get the point so let’s recap shifting is like jumping, and your connection is the gap so you can’t jump wrong, but the gap can be too far so in order for you to make it to your DR you have to close the gap
