The Supermassive Podcast episode on the Multiverse which inspired this video: audioboom.com/posts/8420475-d...
The sci-fi TV show Rick & Morty uses the idea of a multiverse in its episodes and its a brilliant story. But in terms of the science, does it check out? Well there are two main ways of interpreting the idea of a multiverse in physics (both hypothetical and unproven), either (i) the quantum mechanics many worlds interpretation, or (ii) the bubble universes from eternal inflation. So which one does Rick & Morty explore? And how does it compare to other sci-fi shows employing the idea of a multiverse like Everything Everywhere All At Once, Spider-Man: Into the Spiderverse, Spider-Man: No Way Home, His Dark Materials, Doctor Who, Community (Remedial Chaos Theory and the darkest timeline), and Sliding Doors.

👩🏽‍💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

"You might remember doing the double slit experiment in school" we clearly did not go to the same kinds of school lol. The highest level science experiment we did in school was boiling water in paper bags.

Huh? I started secondary school in 1961. We did the double slit experiment. Towards the end of my time there we even did it with discrete photons. This is standard school physics.

[@conradcomics]

Futurama has done both. The quantum mechanics Many Worlds version was the plot of a whole episode. The bubble inflation version was just a first act bit. The latter was in one of the early episodes where Fry wanted to experience all the things that could now be done because it was the future. One of which was traveling to the edge of the universe, where, using a coin operated telescoping viewer, Fry and crew viewed a cowboy universe version of themselves. When asked about an infinite number of them, Fry was told there was only the one, which hints that this was another bubble universe touching ours. The Many Worlds was the Professor made box containing another universe where the results of coin flips were the opposite of their universe.

When Rick C-137 invents teleportation, Rick Prime lectures him about realizing that "traveling the whole galaxy means that you're the last guy to invent teleportation", and then says he's going to invent something much greater. The teleportation device with the blue portals Rick C-137 invents isn't the "portal gun" -- it's just local-universe teleportation. The portal gun mechanism isn't same-universe teleportation, it's many worlds multiverse teleportation.

@@ArmyGuyClaude No, that's fuel for a space ship.

[@Crowelephant]

Can you help me understand what "you're the last guy to invent teleportation" means? I don't get it.

[@robinhodson9890]

It means you tap into a huge existing network of all the other Ricks who've done it before: Then the next Rick who discovers it independently becomes the last one, and so on.

[@timhiers3617]

Given that it's just within the local universe, I would assume it even means that other local-universe aliens have done it, including non-Ricks, since they would still be confined to their local universes. Basically because someone else has previously invented it,, you're just the "last guy" that's done it, not the first.

"Star Trek:The Next Generation" episode "Remember Me" . Dr. Crusher gets caught in a bubble universe created by a "Warp Bubble" that slowly shrinks causing the crew of the Enterprise to disappear and the size of the universe to shrink until she's the only one left on the ship in a Universe 700 meters across. (And the ship's computer thinks this is totally normal)

[@Le3eFrereBrunet]

And the famous quote Crusher: Computer, what is the size of the universe? Computer: the universe is an hemisphoroid region of a diameter of x million kilometres.

[@chinsta00]

The name of the character seen in this and other episodes, "The Traveler", could be an apt description of someone capable of traveling 10^(10^29) metres away to another bubble. That said, dialogue spoken by "The Traveler" makes reference to "alternate realities", which seems more consistent with the quantum many worlds multiverse.

I'm sure someone else has already said this, but The Tardis from "Dr. Who" is described as a bubble universe attached to ours, which is how it travels through time and also why it is bigger on the inside.

[@vigilantcosmicpenguin8721]

Wait, so the Doctor just has their own personal universe? Real estate prices would be through the roof for that.

[@robinhodson9890]

It doesn't matter whether the TARDIS uses a different universe or not: It's just a travelling door (wormhole - except such a door would appear spherical). This also explains how the TARDIS is able to park inside itself - at least this stops the Doctor bothering ofher people for a while.

[@xnonsuchx]

I liked the Doctor Who episode saying goodbye to Rose in another dimension where he says he’s burning up a star to just send a message. It kinda demonstrated the idea that while some things might be possible, the power needed to even attempt them make them impractical/impossible (if you’re not as advanced as fictional Timelords).

[@TheWyrdSmythe]

A key difference between the two is that in Many Worlds, there are branches of a single reality, so doppelgängers are a natural aspect, but bubble universes have no connection to each other, so doppelgängers are purely statistical coincidences and presumably much rarer whereas you’d have an infinite number of doppelgängers in Many Worlds. BTW: the “bubble universe” or “pocket universe” is an old staple of SF that many have mentioned in the comments. These are different from the bubble universes created by eternal inflation. They’re usually smaller and contained next to if not _within_ our universe. “Micro” universes are very popular.

[@fh5926]

If there were an infinite or just very, very, very large number of bibble universes, you'd have doppelgangers there too. You might even have exact copies.

[@trevinbeattie4888]

That reminds me of an episode of “Mork and Mindy” where Mork was literally shrunk down in Mindy’s apartmetn to a quantum scale where he landed in an alternate Earth. And then there was the weak premise of the “Supergirl” movie where Zaltar claimed that Argo City was in “inner space”, and when Kara leaves the city she somehow emerges out of a lake on Earth.

It's worth mentioning that Dan Harmon created both Rick and Morty and Community.

[@vigilantcosmicpenguin8721]

That was actually two different Dan Harmons. It's the same person, but from different timelines.

[@rsaunders57]

The bubble worlds interpretation occurs a couple of times in Dr Who. They make a couple of bubble universes accessible through some sort of rift at the point where they touch. They ignore the prospect of them forming at great distance, and allow then to touch or move inside each other.

[@MaryAnnNytowl]

And Doctor Who tends (well, the writers tend) to play with alternate reality ideas, which are from the quantum mechanics side, as well. The Doctor has no rules, LOL! ❤❤

[@MonkeyJedi99]

You know what sounds better than the bubble universe hypothesis? The Bublé universe hypothesis. Which is to say, a universe exists where everyone is a Canadian singer/songwriter.

It’s not an interpretation, it is completely unrelated. It has nothing nothing to do with quantum physics, and can coexist with other kind of multiverses.

[@danteblankenship6213]

I missed your comment, as I watched this video on my phone. I was suggesting that the void ships suggested a bubble universe, and with either Tom Baker or Peter Davison (I cannot remember which), there were some episodes in null space (which sounds like the space between universes to me).

[@supremeownage8995]

I think the main thing you've missed here is that the Ricks only seem to portal around in something they call the central finite curve, essentially only the universes that have Ricks, or all the new universes forming from existing Rick universes. The series is kinda vague beyond that, other than that Ricks managed to section themselves off from all the other universes where they're not the smartest person in existence. I kinda assumed this was a protection thing, by isolating themselves in their own separate pocket universes they are safe from all the things out there way smarter and more dangerous (That, or an ego thing). This also explains the similarity of personalities as if all these universes branched from "ones with Ricks", they might all share that common ancestry from the moment the central finite curve was created? Regardless, Rick and Morty remains one of the most thought provoking science fictions!

Great video as always. The definitive multiverse show is Sliders. It's about a group of scientists (including Jerry O'Connell and John Rhys Davies) who develop a way to travel to other alternative realities that are similar to our own but still different in some way. It's well worth checking out if you haven't already. Also, after thinking about it, the Myst series of computer games may have more in common with the bubble universes interpretation. In the series, each age (i.e. world that you visit through linking books) is supposed to be its own separate universe, but I don't recall it ever stating that each one exists in its own dimension.

Broiler is a setting on the oven with a separate tray, usually underneath the oven, that turns on the flame to maximum. Used to quickly brown/sear toppings without changing the doneness of something previously cooked.

18:13 The word "broil" means to bake in an oven where there is a heating element on the ceiling of the oven too, and not just the floor. When you run both elements, then both the top and bottom get heated at the same time, and it tends to create a crispy top layer on the baked food.

I don’t remember the name, since I read it in the 70’s, but at least one book has used bubble universes. In the book, each universe is slightly different from the next, and so slightly alters the traveler. At one point, the protagonist and antagonist are in a chase where they move so far away from their “prime” universe that they were both fighting as giant worms. The concept of bubble universes hadn’t been proposed by physicists yet, but this is what the author was talking about.

I would say that Everything, Everywhere, All At Once's version is more akin to the bubble multiverse. They even show a map of the various universes relative to each other, and describe jumping as "slingshotting" long distances from one universe to another. In fact, they describe the universes in the multiverse as being organized with similar universes closer together, which as a computer scientist I geeked out over, because they basically said the multiverse is a latent space, and each universe is an embedding 😁 (Also, for their personalities: the different variants *are* very different, but the whole point of the jumping technology is that it mixes the minds of both the jumper and their destination together, so you get some of each personality, with the jumper's usually being dominant.)

Honestly we do have observational evidence of a Multiverse it's called the Mandela effect and if you haven't personally witnessed some of the things on the Mandela effects list then you have not been living your life to the fullest... ultimately everything is subjective and objective reality can't exist because in order to have objective reality you need to have an observer that exists from the beginning of time all the way to the end of time and even if such hypothetical Observer exists the end of time has not came yet therefore it's all subjective and if you follow the logical progression of the spatial dimensions if a fourth spatial Dimension exists then infinite three-dimensional spatial potentiality can fit into any size four dimensional existence!!!

i think the problem w the bubble theory for fiction are the following: 1 - it implies immediate or near-immediate travel to anywhere within your own universe, which would be an aspect that would be complicated to write for considering how big a universe is and would be difficult to convey in a novel way. what's the difference between a planet 10^10^9m away from one 10^10^19m away within a science fiction universe?? idk maybe you could have your characters visit a very far away anti-matter part of the universe? but that's the best idea i've got. the many worlds interpretation doesn't come with this "spatiality" attached 2 - and most importantly, as far as i understand nothing guarantees our neighboring bubble universes would be similar to ours. heck maybe due to different expansions rates of these neighboring universes, stars never formed, let alone life, let alone different versions of the main characters. meanwhile with the many worlds theory, neighboring universes have diverged more recently, so the same characters are guaranteed to exist in slightly different versions, which is exactly the kind of plot point fiction writers might like to hit! so i think the "many worlds" interpretation is just better for writer convenience and for telling more usual/intuitive stories. though now im curious with how a sci fi piece of media would approach the bubble universes concept!

[@scifirealism5943]

Wormholes could go anywhere But scifi wise- How do you control where wormhole goes? How do you which universe is where? It's always glossed over.

[@hcfornwalt]

I just wrote a similar comment to this before scrolling down and seeing this. As it pertains to rick and morty, they have the central finite curve to wall off similar universes... you're right, adjacent bubbles would not necessarily be similar. So the fact that the central finite curve exists in R&M means it's a multidimensional many worlds storyline. But in any other story that doesn't have something like a central finite curve, I don't see a huge difference between multidimensional many worlds and bubble universes... either your portal moves between dimensions or zaps you to another similar bubble really far away... doesn't change the storytelling.

[@birgitmelchior8248]

Exactly, a bubble universe is, storywise, not that interesting. Stories drive on conflict and recognizing a certain experience. You might somehow travel to another bubble and there might not even be planets or anything familiar. A bubble universe might have different laws of physics, so it might not even be recognizable to us as a universe.

Gen xer here and one of my favourite books from the 90's(at least cheap in the book stores) The Physics of Star Trek.

But I can still dream about wormholes and dream the cosmos.

[@millwrightrick1]

I think the first reference to a many world scenario was Robert Heinlein's story 'Elsewhen". Phil Farmer did do bubble type universes in his "World of Tiers" novels.And then there is Roger Zelazny's Amber novels which played with both concepts, and rather well too.

[@BirthQuakeRecords]

The bubble universe idea is vaguely reminiscent of all the "alternate earth" episodes of the original Star Trek - like "Miri" and "The Omega Glory". But those are mostly just silly intragalactic coincidences, not full blown bubble universes within 3D space (I think the furthest any ship in Trek has ever traveled was to M33). The bubble universe in the Dr Crusher-centric TNG episode "Remember Me" that someone else mentioned in the comments is a bubble universe in name only. It was more like a pocket universe created by a collapsing warp bubble (hence the name). Although it DID have an alternate/duplicate version of the ship and crew within it, so idk

Regarding the Everett interpretation, universes can recombine. If event C depends on either event A or event B, but there is no way to tell A or B led to C, then those universes existed but recombined, since they become indistinguishable. This should happen for only a small fraction of universes.

[@shanecomer6366]

It's been way too many years since I've read it, but I think the last book in the "Ender's Game" series dealt with the bubble universe theory. In summary, and if my memory serves correctly, they'd get into a "ship" where they'd merely think themselves outside of the current universe, then when they pop back into the universe whatever they held in their mind while outside of the universe would manifest for them within the ship. The book this was used in was "Ender in Exile."

[@theharbinger2573]

So I think an episode of ST TOS - Alternative Factor could be an example of bubble universe. Where the Enterprise encounters Lazarus, a being that finds a way to travel to another universe, that happens to be all antimatter. In attempting to connect the two he risks destroying both universes. Could be bubble, could also be extra dimensional. There was a Lazarus in both universes, so it is probably many worlds, but it is a bit ambiguous - if I am remembering properly. It was written in the late 60s, so pretty cool.

[@RyuichiNoGekido]

In Futurama, while there was an episode with a bunch of interdimensional boxes that would probably be considered "many worlds" type universes; there's also an episode where they travel to the edge of the universe and there's another universe waving back at them through coin operated binoculars. That might be bubble, but it's stated that there's only the two universes.

[@shanoukgaming6763]

A basic explanation of broiling. Using the top heating element in an oven at high heat typically 500°F/260°C or higher while using a broiler pan (a pan that has a slit top for grease to drip into). It essentially is similar to grilling on a BBQ.

Kudos for mentioning that classic Community episode! I would highly recommend reading This Is How You Lose The Time War by Amal El-Mohtar. It is an extremely beautifully written novella that won both Hugo and Nebula awards about two persons on opposite sides who start exchanging secret messages. All set against the background of a war that is fought by manipulating millennia of time lines across multiple universes. It is a short story with wonderful details like (non-spoiler) one person describing how she tries to catch a performance of Romeo and Juliet on every assignment, if possible, to see if it is a tragedy or comedy in that particular time line.

[@williambrown9166]

The Flash #123 September 1961 is a pop culture touchstone for bringing out the multiverse to non scientists like me. It may not have been the biggest at the time, but it lead to DC creating a multiverse, years before Marvel thought of it. As a kid in the 70s, I found the whole multiverse idea fascinating simply because of DC bringing the JLA and JSA together once a year. Of course DC and Marvel had the great story tellers and artists changing between the two companies, so they both ended up with it. That and Star Trek's mirror universe were the two that stand out most to a Gen Xer like me.

[@RubelliteFae]

I always found it odd that ST only explored one other universe. Once an author opens that can of worms, it bothers me when they only touch the surface. Same with time travel (which would really just be traveling between different universes of a multiverse by taking the long way around (against the arrow of time and back again instead of cutting across the "now moment"). Once you start that, such a huge number of possibilities are available-so it better be the one of the best damn story from all those possibilities. And, it never is.

[@williambrown9166]

@@RubelliteFae A 90s show called "Sliders" is a great example of that. The premise was exactly that: going between universes where the differences could be big, such as Russia controlling the western half of the US because they colonized it first, to small, like the Golden Gate Bridge being painted blue instead. (The show was set in the San Francisco area). John Rhys-Davies, one of the stars, has talked of his disappointment of the show degenerating into a monster of the week premise, when it could have been so much more. And he was right.

[@RubelliteFae]

@@williambrown9166 Was a huge fan of the first few seasons of Sliders as a kid (though, something about the actor that played the main character felt off-IDK what). The episode where they hadn't yet discovered penicillin always sticks out in my memory for some reason. It definitely fell off over the years. Was a shame how frequently they bumbled their way into figuring out how to help. 😅 Like, they just beat the odds due to luck too often. Loved it as a kid, tho. Also was a fan of Quantum Leap and later a massive fan of Stargate SG1 & Universe (obviously different premise, but similar result).

[@glennmcco]

@@RubelliteFaeI think I might have an answer as to why that is in Star Trek. SPOILERS AHEAD: Star Trek Discovery After the Discovery is sent into the future, Emperor Georgiau is told by a Federation scientist, I think Kovich(David Cronenberg's character), some spiel about the distance between theirs and the mirror universe getting larger, such that getting her back to the mirror universe is impossible with the technology of the Future Federation even though in the past several characters managed to travel and swap universes. I don't know if this is mentioned or alluded to or contradicted in anyway in any other series of ST but it would possibly also mean that this is an example of media using the Bubble Multiverse idea Dr Becky talks about in this video and I hope she sees this comment as it makes her quip about Star Trek towards the end of the video and the fact earlier she mentioned not knowing where to find an example of bubble Universes quite comical. But also, it would mean that if we assume the mirror universe is just the closest other bubble universe, that that is why its the single example we ever see in the show as other Universes would take more advanced or more powerful technology to be able to travel between and the longer after the early 23rd Century setting in the first 2 series of Discovery we're discussing the more difficult it is to even get between these universes.

[@RubelliteFae]

@@glennmcco That's a fair point. I've always presumed the MWI of QM meaning the only thing "increasing distance" between two universes/timelines is the amount of time that has passed since they diverged from each other. This would mean that more recent splits would be easiest to cross between (and also that there would be very little difference between the two). With bubble universes I wouldn't expect proximity to each other to correlate with similarity between the two (probability doesn't care about that proximity). And so, would expect them being vastly different. Thanks for the info. Good to know there's some sense to it even if not the logic of my personal headcannon.

Great series. On post scarcity too.

[@noppornwongrassamee8941]

I think the reason most multiverse stories don't do the Bubble Universe theory is because Bubble Universes is uninteresting. What's the difference between a Bubble Universe and an alien world? Scale obviously, but a story can't get too big in scale - especially visual stories like movies - without becoming incomprehensible to the audience. As a result, a world where Mushroom people rule won't look that much different from a universe where Mushroom people rule, especially if the human characters are only visiting for a half hour long episode or so. The exception might be fantasy stories where you have entirely different laws of physics being the basis for the fantasy world's magic. Which might technically be a bubble universe, but such worlds typically don't interact with other bubbles that have different physics. And a few such fantasy settings sometimes have our Earth - or something resembling our Earth - be part of it.

[@hcfornwalt]

Also, to travel between bubble universes, you essentially need either giant wormholes, or the ability to travel 10^10^10^googol times faster than light in order to move between them. From a narrative perspective, both of those are essentially indistinguishable from a portal gun. I agree that the energy for actual travel at that speed would seem to be beyond infinite, unless you allowed for some kind of strange matter with different properties (like negative mass?) or whatever. No matter what, you're talking about bizarre fictional physics that is just a bunch of words strung together to serve the plot. So from a story telling perspective, I don't imagine there's much distinction between saying 1) your portal transmits you between parallel universes closely separated in additional dimensions vs 2) Your portal opens a wormhole that travels all the way to a different bubble universe 10^10^10^googol km away instantaneously. The main reason why I think Rick and Morty doesn't do the bubble universe thing is that the central finite curve exists as an actual barrier... In a many worlds paradigm, there's reason to imagine that closely similar universes might only be slightly separated from each other along these extra dimensions, so you can "wall off" universes with similar characteristics. But with the bubble universe concept, there is no reason that similar universes would be adjacent... it's totally random what happens in each bubble, and you might have to skip over 10^10^10^googol bubble universes just to find the one in which you didn't eat that third slice of pizza. There would be no way to create a "central finite curve" to cordon off universes with similar characteristics.

[@rastarn]

I remember watching a documentary some time ago, that talked with different physicists, all working at a large, think tank location. One of the many worlds interpretation models proposed by one of them, posited that individual universes hung, ebbing and flowing, like multiple layers of thin sheets in a breeze, at subatomic small distances apart from each other. Every so often, two of those sheet universes may brush against each other, and that would cause a big bang, creating a new sheet universe. I can't remember who it was, but I still love that visualisation.

[@evangonzalez2245]

That's brane theory 👍

[@georgwrede7715]

I used to think that Many Worlds was impossible because it would fill the space, so to speak. But lately it dawned upon me that all you need is an extra dimension. Just like Flat Worlders couldn't "see" the world of Third Dimensions, we couldn't "see" an 𝙞𝙣𝙛𝙞𝙣𝙞𝙩𝙚 𝙣𝙪𝙢𝙗𝙚𝙧 𝙤𝙛 𝙫𝙚𝙧𝙨𝙞𝙤𝙣𝙨 of our world in the Fourth Dimension. (Not here counting Time as a dimension.) -- To visualise this, I told my son that a Monitor has three colors, RGB. With them it makes 256^3 colors. But a bee sees also Ultraviolet. That doesn't mean it sees "one color more", but for all regular colors, it sees each of them having a different shade of Ultraviolet in the mix. So "a bee monitor" would have to show 256 * 256 ^ 3 colors. Having said this, I still feel that Many Worlds is just a nifty trick to escape the revenge of the cat.

[@physics_hacker]

R&M being a many worlds multiverse is also backed up by the episode where they accidently turn the house into a superposition and every decision continues to fracture it. So we know that in R&M, a many worlds situation is possible even just for one garage, so what's preventing that from happening to, say, the whole universe? Probably nothing. It also explains how they keep flip flopping between the ideas that the multiverse is infinite, and that it's somehow finite (central finite curve, "I told you we can only do this few more times!" referring to hopping to a new universe because of a mistake, etc) because the many worlds multiverse is technically not infinite, since you can only have so many branches, but from a human perspective it's effectively infinite.

[@ThanosDestroyeryearsago]

Many worlds being finite or actually infinite is debated upon and not agreed upon. Some believe it to be finite. Others think it’s countably infinite, others think it’s uncountably infinite. So, that’s not entirely a fact. Well, none of it is, but there’s other views on it.

But was really a device that sends the criminals to. Which is a world that is ruled by criminals. The "good cop" sent his doppelgänger to this world. But he soon found his way back. And the weird part was whenever each one killed their opponent they would get stronger. A lot of martial arts were fought. And soon the "good cop" fights his doppelgänger again and sends him back to the "Multi-verse" and he saves his wife. This was somtime ago and I remember they did call it a multi-verse .

[@Pharisaeus]

I would argue that Anathem actually goes also into the "bubble universe" direction as well, considering the matter in other universes visited by Daban Urnud is different from matter in Arbre universe. Basically the "many worlds interpretation" is used to describe what Incanters can do (so inspect multiple narratives inside a single universe), but the travels Daban Urnud does are actually "jumping into another bubble"!

Baking or roasting cooks by raising the ambient temperature inside the oven, and there are convection bake/convection roast settings that use a small fan to circulate the air so the cool food can't cool off the nearby air as much; this results in shorter cooking times. As others have said, broiling is cooking by radiant heat from a very hot element at the top of an oven; it browns or cooks the surface without really heating the interior of food. And just for completeness, boiling down means to boil off water from a dilute solution to increase the concentration of the good stuff. For example you can take watery sap from a maple tree and boil it down to a thick delicious maple syrup!

[@wakkawakka7624]

To Broil is to turn the top element of your electric oven on so the top of your casserole dish gets blasted with heat right at the end of normally baking something. It makes the top that delicious crusty brown look. I also broil a pizza after it's finished so the cheese isn't rubbery. Do not walk away from an oven on broil. You can easily burn the top of your food. You shouldn't broil glass casserole bakeware. But you can broil porcelain bakeware. Sometimes broiling a cheap metal baking sheet makes it warp.
