Is this a reference to the money kind of inflation? 172.70.131.6 16:03, 21 October 2022 (UTC)
- no 172.70.114.205 16:29, 21 October 2022 (UTC)
- I do think it a form of irony that when I hear "inflation" I do *NOT* think about bubbles or balloons. 20:08, 21 October 2022 (UTC)

I think this comic might be referencing the eternal inflation model: as the universe eternally inflates at an exponential rate, bubbles form where the inflation slows down, creating a disjoint multiverse from these bubbles being unable to interact with each other. In this comic, the process is shown as recursive. LegionMammal978 (talk) 16:42, 21 October 2022 (UTC)
- I'm included to agree. Should the article be changed? 20:08, 21 October 2022 (UTC)
This comic would be perfect motive for a mug. Fabian42 (talk) 19:04, 21 October 2022 (UTC)
- Though I think you mean "motif", although I also agree in principle with your word as well, if it does motivate someone to create one... ;) 172.70.162.77 20:33, 21 October 2022 (UTC)
- I also think it's a really good motivation to create a GIF, I came here to find one... If I can find the time I'll do it! Raphaël xyz (talk) 13:05, 24 October 2022 (UTC)
I don't think this comic references the big bounce, but rather the theory of nested universes. The way it works is each black hole spawns a new universe, and is connected to a white hold in the new universe. If true, our universe came from another universe capable of producing black holes, and since our universe has black holes in it, according to the theory it has in turn created additional universes, each with the potential capability to produce its own black holes and therefore create additional universes. It's kind of like universe propagation.
[Responding to the title text:] As a cosmologist, it most certainly does not! Cosmic inflation took less than 10^-32 seconds involving superluminal expansion of points starting the width of a quark from each other. Any physical gas inflating of a membrane is simply not comparable, and if this is a joke about [1] then it's not funny. I would die on this hill if I had time to argue with you all about this. 172.70.211.146 21:52, 21 October 2022 (UTC)
Not sure "The Big Bounce" has currency here, as per the current explanation. That's a cyclic theory (generally relying upon a Big Crunch ending one version of universe, the result sparking the next Big Bang... certainly in the version I would favour, if it turned out we were actually not destined towards untempered expansion and either Heat Death or Big Rip as the unending finale) not a recursively embedding one (e.g. Inception-like realities within realities). But that's just my opinion. Someone who actually finds a Big Bounce model of spacetime more satisfying than any open-ended one, even. 172.69.79.201 22:04, 21 October 2022 (UTC)
- There are a number of cyclic cosmologies possibly involving a "big crunch" such as ekpyrotic theories, but we need telescopes much more powerful than the JWST to say anything about whether they are possible, likely, or propose improvements to them. If the pre-inflationary universe was actually a point, we may never know. There is a large variety of other open questions which are much easier to answer. 172.69.134.131 00:21, 22 October 2022 (UTC)
- Any Big Bounce/Crunch worth describing as such needs a crunch-point (or nearly so). Bubbles from bubbles from bubbles has no crunching and is more Steady State With Continuous Generation (i.e. infill to the expansion out of the visible horizon, as a sop to the evident redshift without subscribing to how that finite age requires a BB origin) if you want to introduce any particular real-world™ theories. It has Big Rip similarities, too, perhaps.
- Bearing in mind that the comic-universe can be anything it wants, without bearing upon what we do/could see. Plus the real© universe is probably yet so much stranger than even our best guesses (and 'disproved' guesses of old) suggest, and we are are still nowhere near the mark. 172.69.79.173 08:24, 22 October 2022 (UTC)
This makes me think of his earlier comics. N-eh (talk) 00:15, 22 October 2022 (UTC)
I just realized the two cueballs are not on doppelganger hills. Perhaps an allusion to, as opposed to their being multiple nested universes, one metauniverse in which our bubble universe (with cueball) actually exists blowing regular, non-universe producing bubbles? 172.70.214.151
I feel a definite reference to M.C. Escher here, his Metamorphosis murals were like this, the end of one part starting another, and I'm sure at least one ended how it started (even if the Cueballs aren't identical, on different slopes of their hills). NiceGuy1 (talk) 06:49, 22 October 2022 (UTC)
If he meant economic inflation, he would have said "...with economic inflation", not "regular inflation". This part of the "explanation" is wrong.172.70.230.75 19:59, 22 October 2022 (UTC)
I could be imagining it, but line drawing the hill on the right appears to be quantized...and I've seen arguments about space quantization that prevents such infinite recursions. Philhower (talk) 13:18, 24 October 2022 (UTC)
