- If travel to other realities and multiverses is possible, then so is conflict between them, but how would a multiversal war be fought?

This post should probably be pinned to the top. I've seen a couple of comments wondering about it.
What stunnes me most of all... how can the fundamental "energy" as for example our dear atoms... how they can build us.. arrange and move to make us.. it is not like they have a brain and advanced enough agreement and communication system or even sight or hearing or senses... how..just.. wow.!
That and indeed how anything exists at all...
My two most mind-blowing... " ? "
And women.. naturally. 💓😉👍
With best wishes for you and yours. ✨️
Hacking the simulation should reference the stellaris precursor empire that committed planned civilization-wide suicide in an attempt to unplug from the simulation

You should pin this comment so that it doesn't get lost in the other comments.
Infinite versions of me are eating a infinite amount of snacks while watching a infinite amount of Isaac Arthur content. Because there are no verson of reality where i dont watch this show!
Also Lenard Nemoy is there and on the show.
A well rehearsed simp kissassing.
Cosmic cheese burgers
Isaac-ception
So that's why I'm always out of cheese-its.
Terry Pratchett's Long Earth series explores the idea of an infinite unpopulated multiverse -"The books explore the theme of how humanity might develop when freed from resource constraints: one example Pratchett has cited is that wars result from lack of land, and he was curious as to what would happen if there was no shortage of land or other resources."
Kane Pixels' interpretation of The Backrooms mirrors that, albeit from a very different perspective.
Loved this book series especially the potato stepper box👍
If you liked this series of books you would love Craig Alanson's Expeditionary Force series, would recommend the audio books version as the narration is brilliant 👍
In a post-scarcity universe, the only things that would be valuable would be intellectual properties and complex devices, since anything physical would be easily reproducible, and this would probably radically alter people's behaviors, because most of us spend our current time accumulating resources, and we would need something else to do !
@@sprinkle61 making intellectual property and complex devices
In Warhammer 40k one Orc warboss travelled trough time to fight his own posse and himself.
For a good fight and to get another one of his favorite weapons..
Thanos does that in one story arc too, it's got a bit of a 'there are no more worthy enemy's to face, so why not battle myself?" flavor that's better than the default evil twin approach
I watch Isaac Arthur to help mend the times between good science fiction and new science.
He is quite inspiring ✨️
There's probably a version of me who became a multiversal conqueror, bringing peace and prosperity across countless universes through armies of ages assembled from across time and space, yet who in his spare time would still watch a video from alternate versions of Isaac Arthur talking about this exact scenario.
By their very nature, no conqueror brings peace.
If we lose to the Ant Universe, I for one, welcome our new insect overlords. I’d like to remind them that as a trusted TV personality I can be helpful in rounding up others to tool in their underground sugar cave.
AntMan only needs to worry about snowplows.
EDF! EDF!
I think you should keep the tinfoil hat on JJ 👽
Love your show JJ keep up the great work and please do a episode on lizard people 😂
I was super into the Batman & X-men animated series in the early to mid-90’s too, I’m glad we have that in common, Isaac
I love these topics too
ha ha ha.... thats the kind of line someone says as they are locking you in a cage in their basement, or going through your trash to find memento's.
j/k
Could you talk about multi dimensional empires or systems of governance throughout time and realities ?
This is actually an idea I've never been presented or possibly fathomed. Warhammer God Edition
@@michaelmoran6364 Warhammer 500,000 million, when the 50,000th chaos god is finally born, Matt ward, reviving the Ultramarines and one shotting everyone else, because obviously they are the best and leading humanity to rule the universe because did I mention the ultramarines are the best?
This episode reminds me of a short set of stories in the SCP Foundation called Project Palisade. A prime version of the aforementioned Foundation invents a device that creates alternate universes and its through this device that they find out that 1) the prime timeline is but a speck in the multiverse around it and 2) a higher plane of universes are having a war that humanity can never comprehend and a shrapnel of a weapon launched from a grunt in that war is launched directly at the prime timeline and humanity assumes its a universe-ending threat so they used the universe creating machine to create the titular palIsade: a bunch of universes to shield the prime timeline from that shrapnel.
Lmao I like how to avoid having their own universe get but they just create others to take the hit instead. I hope these universes are uninhabited
@@ianharrison5758 some are, some aren't. While they create these universes, they experiment with some in order to develop something called reality stability (the capacity of a given universe to survive extrauniversal sources of destruction)
Any time someone talks about Copenhagen, I remember reading Stephen Baxter talk about the Friends of Wigner. That the observer himself is also a quantum event, and he requires a friend to observe him to see what he actually observed from the possibilities, and that friend requires a friend to observer him, and so and and so on, until at some point, you would reach the final, ultimate friend, the observer that collapses the quantum states of every possibility that has ever happened in the universe, collapsing the multiverse into a single timeline.
Or........the Copenhagen interpretation was created by fallible humans who came up with something that simply sounded better than saying "I don't know."
@@Vaeldarg it’s just a sci fi book
Yes I read the this book. Transdence is very interesting begin
@@AbdullahSAHIN-nz2md loved it
Re: previous iterations of the universe: one of the origins for Unicron was that he ate the previous universe before going into a dormant state, but missed the last remnants for whatever reason, allowing it to respawn. So a hypothetical Marvel/Transformers crossover could result in a Unicron vs Galactus showdown, one or the other says "Time for Round 2."
I believe Michael Douglas referenced the Kardashev scale in Quantumania, saying the ants achieved a type II civilization
I wanted to make so quantum-related joke, but in this reality I will simply note that somehow your videos have an ASMR effect on me and thus are both educational and relaxing at the same time!
I actually have a problem with falling asleep during them (despite finding them interesting). There are a few other channels I've noticed the effect from, all of which I actually enjoy. I think that it may have something to do with the rhythm and cadence of the speaker.
In one case, it's actually a DCS flight sim channel. I think that it may be the "highway hypnosis" effect of the constant jet engine sounds.
Why did the photon need to check into a hotel?
Because it didn't have enough energy to make it home!
Forget the amazing ideas for overall topics you come up with on your own and / or with whatever outside stimulus you also experience, I am blown away how well you are able to provide so much more to expand upon those ideas into possible ways to achieve it with technology we may or may not even have yet plus probably a couple of ways we may NOT be able to and then remind us how much we simply can't imagine just like people from barely a hundred years ago would see much of today like literally beyond what "crazy" stuff we thought we knew at the time. Your videos are absolutely wonderful to watch and listen to! 🤯 ❤️😁🙃
The “shield protecting your local reality” reminds me of Star Trek Voyager’a Year of Hell.
Recommended for multiverse lovers:
The 2011 movie Another Earth.
Ted Chiang's story "Anxiety Is the Dizziness of Freedom."
Steven Gould's novel Wildside.
This reminds me of a book I read a few decades ago about two civilizations that discover the mulriverse and eventually meet and go to war. Once if was classic fantasy is dragons, magic, the other was an advanced civ. No longer remember that series was.
There is an anime with the same premise called Gate
Dr Isaac Arthur and the Multiverse of Warfare!
That actually explain how there are countless 'first rule of warfare' - superposition.
Ooh I asked for a Multiverse vid a while back. Isaac never disappoints!
well, not this version of Isaac
Maybe it's because I have been listening to the great book, but at around 18m15s, you say an exact quote from it.
Specifically, from the great wise man who sits on top of poles spring, summer and autumn.
"You can only know what you can know".
Such great Arthurs.
One of the best episodes in quite a while
Thanks a lot, Isaac! I just exclaim with glee anytime you talk about the MCU.
My pleasure! :)
👍
If you use the single particle decay system to pick your lunch you do not know what you are eating until you taste it.
Most of them would be mundane. I think a lot of the tourism/scientific interest would be for those weird universes where insanely unlikely things happen in mundane situations... like one where someone assembles a bunch of monkeys and they actually do produce the complete works of shakespeare.
Downside is... as soon as all the multiverse aliens come to check out this bizarre anomaly, the whole place will collapse into a black hole.
Moral of the story? If you see a monkey start to type out shakespeare, be warned: The end is nigh.
This has been one of my favorite shows yet. You totally rock Isaac. Thank you for the amazing ride. I'm hooked. Lol
My Man!!! Thanks for awesome content as usually.
Biiiig fan here .
I just came across your channel and this video. Highly enjoyed it. And definitely love to shout out to my other favorite channel comics explained. He also educated me a lot on the multiverse and all things comics. I will continue to be a view of your channel and a new sub. Look forward to your future content
They have a lot more resources but they also have a lot more space to expand into, disproportionately more space in fact as the volume of space they would have to colonize rises with the cube of the number of universes they claim, whereas the number of resources they have only rises as the first power of the number of universes they claim.
Thank you this Chanel is definitely my favorite on TH-cam please never stop and if you must create an ai/clone of yourself to keep the Chanel going
Thank you so much for your content every week Isaac ❤️
always upvoting this amazing content creator that Arthur is . FULLSTOP
Really appreciate your work and the way you express information 👍🏻
Love your accent 😍
One of my favorite Authors, Dennis E. Taylor has a good one using this called Outland. Highly recommend it.
I'm particularly excited about the next episode. I would love to know more about Alpha Centauri and how to get there.
For the parents: your toddler is in a nice clean room you turn your back to the toddler for one second. By no longer observing the toddler they have entered a super position of mess. All possible messes the toddler can make has in fact been made. And it is your observation that causes the mess to leave that super position. Thus if you look the mess will in fact be your fault. So have a partner look first, then you can blame them for making the mess.
Or, alternatively, get them to clean it up!
Saw Kang last night and it was pretty funny , decently good movie. Low key (no pun intended) Kang is the best part of the McU right now.
Kang and Dr.Doom are the best antihero’s imo.
As far as the current MCU goes that's not a very high bar to meet...
@@higgsbonbon meh , they got big and think they don’t have to try. Likely waiting out till they get X-men to really go ham with mutants because at this point it’s kinda sus they haven’t shown up, plus the secret invasion and all that not too far off. Basically filler time but it’s not “bad” per say
I think a little plug for the Long Earth series needs to be gently inserted here. It would be a good answer for the Fermi Paradox as far as aliens are concerned but leaves us with the question: "Where are all the humans?"
this episode totally reminds me of the Long Earth series written around ten years ago. Great series BTW!
We need an “inter-species breeding” or a “Sexy Aliens” video.
the Captain Kirk principle
They... don't? It'd be easier to breed with an oak.
Unless you're talking more about different human-descended species interbreeding.
@@boobah5643 that can be one of the more plausible pathways that are explored.
the first thing i thought of when you were talking about quantum mania was the improbability drive from the hitch hiker series, god i love these books.
Love this channel!
When I see "Multiverse Warfare", it reminds me of the trilogy of Philip Pullman - His Dark Materials.Not very scientific story (not to mention kinda controversial 😅), but still - I like how the author imagined the beings that evolved differently in the parallel worlds, and how even four legged critters can develop human level of consciousness. As long as they have some "creative" limbs, like we have hands, they can become consious and develop at least some sort of primitive technology (fire, metal casting, some sort of wheels, maybe biotech, flight etc). It makes me wonder if we will ever find such beings someday ... somewhere. I guess time will show. Thanks for the episode!
on sliders theres multiverse warfare fought by factions that started as planetary civil war
You're one of the best youtubers Isaac
A what?
Hey Arthur.... what do you think about the Three Body Problem's "Sophons"? it fits well with this episode.
Brother Soldier, thanks once again for another excellent video. -Your placement of “Red Giant” by Stellardrone was superb! -I’d like to say this, also: I, speaking solely for myself, miss the math. I’m not a physicist. I am not a mathematician. But, out of a 30 minute video, your throwing an equation on the screen and taking 30 seconds to explain it, serves to “hammer home” that your mission is in fact based in actual science.
-Hope you and yours are well. -C.
I am just wondering about your mind. How refreshing to find a functioning, ordered intellect. Would you mind sharing a bit of your background illustrating perhaps just what has led to your outlook and understanding of matters? I find every one of your presentations fascinating. Thank -you so much!!! I thoroughly enjoy listening to someone more intelligent than myself who provides many new avenues of thought for me to wonder through!
Cosmology says no specific point in the Universe is special. That should apply to all universes of the multiverse, too. 🤔
Not exactly like that, it means on average you will find yourself in an average location of the universe. Applied further, we could expect most other universes to be similar to our own
We don't use beta decay in any clocks that I'm aware of. We do use beta decay to produce random digits. We use cesium and excite one (or more, I'm not entirely sure) of its electrons to a higher state, and then use the time it takes to "decay" to a lower state as the basis of timekeeping. We also define a second now as some multiple of that tiny time unit for a Cesium-60 atom's electron(s).
Every episode is so interesting.
Kang I've got my eye on you; Rick? don't you do it. there's a lot of similarities between this and multiplanar warfare in D&D, highly compelling.
You mean Blood War?

Thanks Isaac, your explanation has brought me a....Quantum of Solace.
The best part about time travel that if it ever gets invented, then it already will have been.
This is one of my favorite topics
i know this channel isn't normally a movie review channel, I think a review/explanation of Tenet would be great... the inverted entropy and following characters around is super fascinating
It's pseudoscience*.
There'd be nothing to review.
(*nonsense)
You are a good man Isaac! Doom is the most patrician choice!
Hey so I've got an idea for a paradox drive, on this topic: Cause a paradox, and make the path of least-resistance involve propelling something. Spaceship I'm thinking. Clarketech, but maybe there's something. If you've got time travel, this might work.
I am 22 seconds in, and my thought is, I could spend a few weeks watching SFIA videos, and have the raw material for a series of awesome SF novels. Which I have no time to write. But, Isaac, you are in the fictional acknowledgements of my fictional novel.
Great video Isaac love l The Kang video
I was way earlier but my alternate self turned into a dog and made a ruckus in front of my window in order to prevent a butterfly effect that would've wiped out this timeline.
So is there any "long root" examples of travel across different incarnations of Universes like how Galactus learned to exploit the Phoenix Force to protect him between Universal death and creation events essentially allowing him to go the long way between one universe and another?
Time travel and multiverse stuff reminds me of The Ship of Theseus in a way.
That's an interesting analogy to use and one I might borrow
What I love about Marvel is their answer to which model of the universe is correct: "Yes."
That's what happens when your 'world' is a fantasy kitchen sink.
you should check out ABC Warriors and Nemesis (2000AD)
The actually weird thing in Copenhagen interpretation is that it is assumed that the superposition "ends" when you observe it, instead of you "splitting" into versions that coexist next to each other.
There is no reason for this assumption, other than "That can't be right, this conflicts with my world view".
As far as I know, there hasn't been a proven upper limit on how many things can be entangled in a superposition, and the reason for this is easily shown by imagining yourself standing in another box, when you go to check on Schrödingers Cat. Schrödinger is outside that other box, and you are in a superposition which "inherited" the superposition when the cat's superposition "collapsed" by you opening the cat's box, from his perspective, whereas "to yourself" you are not, and the superposition is just "gone" or "collapsed".
One could then project that out further, and say that each time any superposition happens, this is part of the entire universe, and once it "collapses", the universe itself just "inherits" that superposition...
... And look where we are going! It's the Many Worlds Interpretation! What?! Whom?!
Yeah. As I understand it, Copenhagen is just Many Worlds, with an arbitrary extra rule (and resulting complications) to preserve whatever notion they had of a consistent universe.
If you spot mistakes, please let me know, always happy to learn :)
(As the saying goes, I love being right so much, I change my mind when I am wrong^^)
P.S. Excuse the long sentences. German is my first language. I'm sorry.
P.P.S.: This is not my original thought, this is just a compression of discussions I have read so far. Can probably find at least one link, if curious.
P.P.P.S. Turns out, Isaac mentioned roughly this. Since he later says that people just "pick favorites", I'll leave this here. While we don't know which Theory is true, some are logically infeasible.
I love how nearly every time you discuss war, the conclusion is "there are way too many cheaper/easier alternatives for it to be worthwile".
This is true for our world as well. Yet…
I remember an Asimov story I read as a kid. The primary protagonists were weird aliens in another universe, some kind of floating blobs that could phase in and out of each other. The story centered on their contact with earth scientists on the other side of a dimensional gate. Due to different fundamental constants in our respective universes, we could never survive any "travel" between universes, but the differential between universes allowed some energy extraction or something. However, in the long run, the bleed over of reality from our universes would cool atomic processes on their side and heat them up on our. Their chief scientist hoped that we wouldn't figure that out before our sun went nova, giving them an actually unlimited energy source by just opening a portal.
Anyone else remember that one?
That sounds like the Gods Themselves,.
@@isaacarthurSFIA Yah, that rings a bell.
Great, now I have to deal with Schrödinger's Observer along with his Cat. Stop locking living creatures into boxes, Erwin!
this makes me think of the combine in half-life they travel to parrallel dimenisions to colonize worlds
I find it amusing how many of us think war would actually be fought on such a scale. If beings had the power to do such a thing they'd most likely look upon war as something primitive alien species struggle with in early development.
I'm pretty sure the only people who say things like that believe that they're entirely rational, and that everyone else is, too. Which ignores a few details: The same facts applied by different values yields different preferred outcomes, even when everybody is rational; the relative worth of different desirable things isn't subject to logic; and most people don't make all their decisions rationally, nor should they be expected to.
And from a darwinist standpoint, ideas that claim they aren't worth killing for will lose to ideas that claim they are.
I bet there is a Interdimensional Council of Isaacs keeping multiverse rolling for a better tomorrow. 😁
the long earth series does a great job at painting how human migration would go if we found access to parallel universe. if you haven't checked it out i would advise it!
terry pratchett co wrote it. so its kind of out there. a reincarnated monk in an *AI* is a main character.
Thank you so much for your content Issac, it helped me to become more disciplined intellectually. and is endlessly intresting!
Love the shout out to Zelazny. Thanks much!
I would love Issac be a science/sci-fi advisor for the game No Man’s Sky.
Last I checked, the MCU still followed a core rule of Futurama's time travel; a time travel duplicate is always doomed. Although apparently with the caveat that the doomed copy can avoid an early end if the local original is killed instead - see Gamora for this. She was already dead so the replacement isn't (probably) doomed. But the alternate Nebua? Doomed. The time heist crew left the past and canceled out the doom, while Captian America just laid low until he caught back up with the MCU present, and his local original was frozen solid most of the time.
Even in the Copenhagen interpretation (which is obviously wrong), you know the outcome the moment any light or other energy interactions causally reach you (at the speed of light) after the "observer" opens the box. Just because you don't see the observer doesn't mean the outcome of the collapse hasn't affected you, and, because it has affected you (lightspeed x distance) time after the observer opened the box, there's no superposition persisting because of YOUR uncertainty as a conscious being. The matter and energy around you "knows" (has been causally affected by) the reality the observer encountered, even if you remain ignorant.
It would be interesting if two rivals invaded the other's dimension but the flow of time was faster in one dimension and slower in the other. If the faster one invaded it would appear to the defenders of the slower one that the enemy was attacking in hourly intervals whereas if the slower one attacked the defenders of the faster one the defenders would experience attacks occuring in intervals that seemed like weeks or months.
Into Isaacverse
Been waiting on this one.
After considering the issues with infinite improbability one may come to the conclusion that the idea essentially handwaves all of reality. I think this is the correct conclusion and should be neither alarming nor otherwise consequential as it only exemplifies something we already knew: That nothing can truly be known and we can only do our best.
I like to think that the universe is infinite in all directions, that whether you go left, up, north, or up or down the scale or up or down the timeline, eventually you'll find another Earth. Even if it's just infinite in one direction, it would remain true, as long as you're looking in that direction. Hard to get to those places/scales though, so it makes for a nigh impossible-to-traverse multiverse, but it makes more sense to me than slightly altering your vibration when each particle in your body vibrates at least a little differently from the rest already or universes budding off of the choices we make, given that those choices are entirely bound by the laws of physics in this universe.
Colonizing the Multiverse is the solution to the 'Dark Matter and Dark Energy' questions ... [dramatic theme music] Dun Dun Duuuuun!
I always wanted an April Fools episode of the TV show "Sliders", where they jump into the portal and end up in one of the MANY, much more likely, Earths where the planet didn't form at all, or didn't have life. IRL, I consider Multiverse ideas to be on the same level as Religious claims; unfalsifiable fun, but not science.
They did end up on lifeless Earth's twice that I can recall. The first universe that Quinn landed in where San Francisco was devoid of life and was a frozen hell with ice tornados. There was a second episode where they did land on an Earth where complex life didn't take hold and it was mostly barren. They also landed on an Earth where everything was gigantic and they were being chased by a carnivorous bunny the size of a truck. 😆
If the planet doesn't exist/is inhospitable, you don't get enough television to fill your forty minutes of airtime.
5 dimensional Stellaris with multiverse time-travel
Theres an Earth out there where Star Trek has played out exactly like the shows. Same with most other works of fiction. Thats kinda cool if its true.
I.A. using Futurama to extenuate his point; GENIUS. Again.
Weirdly, I cut away from this for breaking points coverage of the ongoing fall out from that chem train derailment, and that's never happened with Arthursday before....
I just realized how close this was to Ashtabula. Are you guys okay?!
On a long enough timeline, the probability of shuffling a completely ordered deck goes to 1.
- I. Arthur
But, so does the likelihood of being unalived.
- The Narrator (Fight Club)
Yet so does the likelihood of being "re-alived".
I don't recall voting for this episode topic 🤔 but I would have. 👍 👌
New Fermi paradox solution just dropped. Time travelers collapsed their worlds into black holes.
Hmm 🤔 you know I've wanted to tackle writing a book that tackles the idea of The Multiverse. Have a character that's trying to stop a villain from conquering it, and even though he fails in some universes he understands that he only needs to succeed in one of them, so the story fallows him and his multiverseal clones around as they constantly get closer and closer to the goal of defeating this villain in every universe, and while he dies in a lot of different universes the story will always pick right back up with a new clone, that hasn't died yet, right up till the time he succeeds.
I'm at about the 3 minute mark right now and wondering if Isaac is going to talk about the long earth series
Given enough time whatever initial conditions that made you today will also create you again one day. We are all virtual particles who's natural state is the void but for small glimpses of time we exist in the most spectacular way
"Observation" in regards to quantum stuff is a misnomer. A better word would be "interaction", particles "observe" other particles by interacting with them, and thus particles (or collections of particles) themselves act as observers for these experiments. In the act of interaction, all the measurement stuff is revealed.
So this is just infinite improbabilities issues 2.0, great cuz its my favorite episode
*now* we're getting head-splitting
Michael Moorcock's Eternal Champion series covers this (in a more fantasy, not so much science fiction standpoint)...and he is the one who coined the term multiverse (last I checked).
In the Corum cycle the 'gods' basically closed off a couple dozen universes so it was a cul-de-sac/closed off from the bigger multiverse: which made 'scaling' (moving between the universes) in scaling ships into/out of the group difficult: effectively making an absurd 'castle' defense around your own universes.
Yeah Moorcock and Zelazny both played with the concept a lot in their works in the 70s, more fantasy than scifi but still very good stuff
@@isaacarthurSFIA
indeed. They don't get the credit they deserve.
Although, I'd tend to think there is a trans-universal fermi paradox that comes up if we don't take the Copenhagen approach:
IF universes/realities can be bridges/crossed...where is everybody? Even a Kardeshev I/II civilization could achieve the ability before gaining control of their entire universe (or even a dozen galaxies).
One could envision the K1 civilization that discovers inter-universal travel and uses it to exploit 10k other Earth's for various resources: never leaving their solar system.
.
...Let alone a Kardeshev III/IV or beyond that just does the same but rather than 1 planet: entire galaxies.
...It would seem to posit either its too abstract/difficult a feat to achieve; that copenhagen principle is correct (and they may as well not exist) or that life is so incredibly, stupidly unlikely, that the chance intelligence at our level even arising across a multiverse is unlikely.
Wow! I was already a fan, but just to hear Karl Popper mentioned, oh Anywhere... You da man Isaac
