For me it is Cellular Automata, and more precisely the Game of Life.
Imagine a giant Excel spreadsheet where the cells are randomly chosen to be either “alive” or “dead”. Each cell then follows a handful of simple rules.
For example, if a cell is “alive” but has less than 2 “alive” neighbors it “dies” by under-population. If the cell is “alive” and has more than three “alive” neighbors it “dies” from over-population, etc.
Then you sit back and just watch things play out. It turns out that these basic rules at the individual level lead to incredibly complex behaviors at the community level when you zoom out.
It kinda, sorta, maybe resembles… life.
There is colonization, reproduction, evolution, and sometimes even space flight!
- Free software
- Group theory, Church notation and Lambda Calculus making many things in Math under one roof
- Design of CPU and Operating Systems. Both fields are made by geniuses.
I was kinda oblivious to the world of FOSS until simultaneously switching to Lemmy and also resuscitating an old computer by installing Linux. It took a long time for me to wrap my head around the fact that people are just cranking out parts of OS’s, or pw managers, or file zip utilities for shits and giggles in their free time, and not even charging for it. A game or two as a passion project I could understand, but who sits down after work and plods through a zip utility?
After years and years of “if the service is free, you’re the product” it really takes some time to rewire my brain. It’s almost enough to make me wish I went into software instead of mechanical, so I could pitch in on something.
You could design parts or projects for 3D printing
The concept of emergence blows my mind.
We have this property in our universe where simple things with simple rules can create infinitely complex things and behaviours. A molecule of water can’t be wet, but water can. A single ant can’t really do anything by himself, but a colony with simple pheromone exchange mechanisms can assign jobs, regulate population, create huge anthills with vents, specialty rooms and highways.
Nothing within a cell is “alive”, it’s just atoms and molecules, but the cell itself is. One cell cannot experience things, think, love, have hopes and dreams, or want to watch Netflix all day, but a human can.
The fact that lots of tiny useless things governed by really simple rules can create this complexity in this world is breathtakingly beautiful.
Kinda ties into your example :)
Reminds me of the statement that you can’t dissect a rabbit to find out why it’s cute
Won’t stop me from trying [joking]
Don’t, rabbit necropsies are the worst smelling thing you’ll ever encounter.
How come? Why rabbits specifically?
Not sure why, just that I was in a building when one was being performed and it stunk up the whole place to the point I almost went home because I was going to vomit. My boss put out a bowl of liquid that neutralized the odor, thank god.
Just like the trillions of parameters that make up machine learning models that can speak or create images

Dear God, it’s beautiful. (And genuinely seriously important)
It kills me how much more of it there’d be, and how much better off we’d be in general, if we weren’t forced to spend so much of our lives working for other people.
Now we’re at a top 3 idea which haunts me. We have everything to make life so amazing now, but we just can’t let go of these defunct paradigms that drag us down into a lower common denominator existence.
Alan Watts contextualizes our daily lives as the outer, “fine spray” at the edge of the big bang --still exploding. Planets “people-ing” and your daily schedule, relationships, accuisition of goods, etc. is just the complex late stage of the big bang explosion. The explosion is chaos but as time goes by order slips in and creates “complexity”. This is all still an explosion.
Symbiosis in nature….it always brings up feelings of awe and wonder for me. Especially in forests. The “wood-wide web” or “mycorrhizal network” being my latest obsession . The fact that the fungi joins the trees together through the roots to allow for exchange of nutrients, water, and chemical signals between plants. And then there’s the forest canopy, and the role it plays in keeping the forest healthy.
Trees are awesome.
Evolution as a concept; not just biological. The fact that you can explain the rise of complex systems with just three things - inheritance, mutation, selection. It’s so simple, yet so powerful.
Perhaps not surprisingly it’s directly tied to what OP is talking about cellular automata.
DNA still blows my mind. Some weird simple molecules that just happen to like to link together have become the encoding of how complex biological systems are constructed. Then mash two separate sets of DNA together, add a little happenstance, and you have another new being from those three things you mentioned.
There’s something interesting in here about the persistence of legacy systems that I can’t quite put my finger on. Rest assured I will be consumed by the thought for the remainder of the day.
There are plenty things that we could talk about legacy systems from an evolutionary approach. It’s specially fun when you notice similarities between software and other (yup!) evolutionary systems.
For example. In Biology you’ll often see messy biological genetic pools, full of clearly sub-optimal alleles for a given environment, decreasing in frequency over time but never fully disappearing. They’re a lot like machines running Windows XP in 2023, it’s just that the selective pressure towards more modern Windows versions was never harsh enough to get rid of them completely.
Or leftovers in languages that work, but they don’t make synchronic sense when you look at other features of the language. Stuff like gender/case in English pronouns, Portuguese proclisis (SOV leftover from Latin in a SVO language), or Italian irregular plurals (leftovers of Latin defunct neuter gender). It’s like modern sites that still need animated .GIF support, even if .WEBM would be more consistent with the modern internet.
The Elitzur–Vaidman bomb-tester, specifically (https://en.wikipedia.org/wiki/Elitzur–Vaidman_bomb_tester).
Next, that I can buy and program a computer for 0.30 USD that’s half the size of a grain of rice (ATtiny10). There are cheaper too, but that’s the one I like.
Finally, on to the horrifying: Boltzmann brains. The idea that given a reasonable interpretation of the laws of thermodynamics, and long spans of time, the most common form of brain in the universe ought to be one that forms due to random fluctuations. It exists for long enough to have exactly one thought (e.g. recall a false memory), then dissipates.
This ought to be by far the most common form of conscious mind in the Universe. In a sense, you could say it ‘blows’ the general case of minds.
Since you are a mind, statistically, you ought to be a Boltzmann brain. You may not be, but are unable to prove otherwise, even to yourself. So either we have some things left to learn about thermodynamics, or the most probable outcome at all times is that you cease to exist immediately after having your current thought (although I hope you don’t). Sleep tight!
Galaxies are not evenly distributed in space. Instead, when you look at the universe, galaxies are grouped in giant strings that look like a neural connections in a brain.
It blew my mind when I learned that we’re in a relatively dark, empty part of space compared to what’s out there. It really put into perspective for me how difficult space travel will be for us as we continue to advance.
Space is incomprehensibly big and its getting larger over time. We will never have meaningful travel outside the solar system. If humanity started traveling in space from the moment we evolved, we would be able to travel the length of the milky way around two times. Space is basically a boondoggle. Our solar system still contains lots of resources though, so its not totally worthless.
Yea … like Star Trek, with warp speed and everything, is basically all limited to our single Galaxy … and that’s not unrealistic given their technology.
Like in that space-faring future, the galaxy is basically the new continent and the inter-galactic divide the new great ocean that no one has ever crossed.

Part of the beauty and awe I get whenever I reread that famous excerpt from Carl Sagan’s Pale Blue Dot is the sense of how ephemeral and delicate our existence, and even the very human concept of “existence”, is. We are infinitesimally small and yet, through no fault of our own, our days, how we fill them, and the people we know hold some measure of importance to us. And it will all be gone - eventually. It’s a very somber note yet it makes me feel a certain sense of peace.
“Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there–on a mote of dust suspended in a sunbeam.”
thermodynamics. it sets hard physical boundary to what happens spontaneously and what can’t, how much energy you need to pump in or can recover from process, but not only that - it’s very broadly applicable, including large parts of chemistry, biology, information theory and more, like this https://en.wikipedia.org/wiki/Dissipative_system
The beautiful idea that blows my mind, is how much better the comment section for a question like this post presents is on Lemmy, than Reddit!
Anarchism based on mutual respect and aid. It’s truly beautiful.
Black holes and the uncertainty of what lies behind the event horizon. The possibility that inside a black hole, a whole new universe could exist without us ever knowing. When tripping through life taught me one thing, it is that many things can be seen as part of a huge fractal, and that view fits right into the interpretation that black holes are nothing else than universes in universes. After all, our big bang might just be another ordinary black hole, reaching critical mass.
Of course I can not prove it, but I love thinking about it.
Anyone able to ELI5 why wormholes and dimensional pockets are prevailing theories on black holes?
Like, I’ve got a lot of sci-fi under my belt and I need to figure out the sci part of it.
