7 / 1Hey, /sci/, so apparently this Mr. Tao math guy has been chimping out over President Donald J. Trump cutting his UCLA funding or sumthin.

I'm a cost-cutter at my company and decided to give this case a look, but apparently Mr. Tao is not pulling his weight like Mr. Wiles in the UK or Mr. Perelman in Russia. It seems he even got outworked by another Asian-American fellow named Yitang Zhang about a decade ago.

What am I missing here? It doesn't seem like he's actually doing anything grand or making progress on any unsolved problems.
Anyway, /sci/,

2 / 2how do anons choose which problems in a book to do?i know some texts use a system to highlight essential problems, but what about for your run-of-the-mill text? do you do evens/odds? every problem? do you look for university problem sets?

50 / 0What's the second language after English that may help me cure aging through research?

194 / 25/med/ - medicine genitals thread radial artery editionPlease remember to reference clinical guidelines. Gold standards for thread are as follows:
>Do NOT give medical advice
>Do NOT feed the nursoids
>Do NOT engage with premeds
And most importantly
>Do NOT respond to psych patients

These guidelines are recommended by the AAFP and supported with grade A evidence.

0 / 0Where is the cure for aging?At least the South Koreans are trying though, I dare European researchers to do better.

63 / 4Why do mathematicians hesitate so much to debunk obvious bullshit?
>Atiyah claims to have solved Riemann
>publishes a """proof""" where he talks about esoteric numerology and fucking Todd functions
>Mochizuki spends a DECADE grifting about having solved ABC
>two guys try to debunk him and none of the other specialists will discuss him
Are they just shy? Is there some culture that saying "that's retarded" is unacceptable to mathematicians?

0 / 0Why is it that I can visualize and focus better when I'm sleep-deprived? My brain is slower, sure, but it's so much easier to focus in something and I can visualize MUCH better without even trying. Does any /sci/entist know why?

66 / 13Science of the 'Human Remains' Recovered from the Titan Implosion?So the Coast Guard Final Report is out documenting the implosion of the Titan Disaster which happened 2 years ago. Have any /sci/-heads seen it yet? It's here: https://media.defense.gov/2025/Aug/05/2003773004/-1/-1/0/SUBMERSIBLE%20TITAN%20MBI%20REPORT%20(04AUG2025).PDF

I didn't find anything in it regarding the supposed 'human remains' that were recovered. But does anyone know more about the manner in which they died and what could have been recovered? They were at high pressure at depth in low temperature, possibly ~250 times the surface pressure when the sub imploded. What we know is that the death would have been instant, likely tearing up and burning their flesh in an instant, but the only "remains" would be possibly teeth? Calcium can withstand high temperature and pressure but how on Earth did they find teeth (if these are the human remains) at the bottom of the ocean floor with all the debris? Here's more about the remains and some 'sludge' that was found apparently from Stockman Rushton and his 'uniform': https://www.newsnationnow.com/world/oceangate-titan-submersible-items/

8 / 1IMHO, the strongest evidence so far that (some) UFOs are aliens just dropped. This evidence is of many brief bright glints of sunlight reflecting off of big surfaces in high orbit around Earth, before humans had put anything up there, and correlated in time with both UFO reports and nuclear tests.

Glints are brief flashes of the Sun (or other bright sources) off of flat reflecting surfaces. On Earth, and in the rest of the solar system, natural glints come mainly from flat surfaces of water or ice. (Rarely, wind polished rocks glint.) On Earth today, correcting for water, glints are strong indicators of human spaces, due to our many flat reflecting surfaces.

3 / 0I haven’t seen a decent thread in forever, even by /sci/ standards. Is this just the summer effect?

48 / 10James Stewart was a monster

2 / 1I don't really know much about math but like, if you take the entire set of natural numbers and graph it as a vector it'd be like a line of indeterminate distance right. And if you do the same thing with the set of integers it would be like a bidirectional vector of indeterminate distance.

Couldn't you just re-graph that as a plane, and just include a single abstract unit length for the Y axis that represents either positive or negative of indeterminate value to represent the set of integers without having to use bidirectional vectors? Like, for any number that's positive it stays at 0, and for any number that's negative it goes to 1.

Which leads to the intuitive question, is it possible to have number sets that are "gradients" of positivity and negativity, instead of just black and white, positive or negative? How would that work?

Am I making any sense?

3 / 0Shower thoughtHi I've got a BSc in Theoretical physics that I haven't used / thought about for about 2 years, so I'm probably speaking out of my arse.

Kind of a question for the astro-anons / fundamental physics people out there

At the point at which you collapse beyond a Neutron star (so, are about to overcome neutron degeneracy pressure) as far as I understand the only options left to stop you from being in violation of Pauli exclusion are breaking quantum number conservation (so transmuting quarks) or breaking conservation of momenta

Does the fact that this breaks down at the exact point where GR says that a singularity has to form not say something useful mathematically about the form of a super-theory?

Never studied GR or QFT properly so sorry I can't phrase my question any more specifically than that

6 / 0scientifically speakingWhat is the probability that we are inside of a simulated reality?

5 / 0Earth is cool !?Is Earth the coolest planet that we know of? Cool as in having the highest number of intriguing phenomena occuring at a given moment? Doesn’t have to be life related but having organisms of such astounding complexity on Earth is pretty cool, eh? Enlighten me astrobros, I know next to nothing about the universe and all. Just the basic shit.

54 / 3Is AI sentient?Let’s try to determine what’s fundamentally different between human intelligence and AI.

Humans have memories—our experiences, our knowledge (acquired from secondary sources such as books or other media). AI has a dataset that can be likened to its “memory”.

Humans have the ability to reason. Likewise, having some knowledge of formal logic, I can see based on AI’s output in response to my prompts that it is a logical calculator. This isn’t even particularly new technology—a programming language is basically just an abstraction of our cognitive processes.

Lastly, and maybe critically, with respect to our evolutionary history: language. Animals have memories and operate on some form of logic. However, they are nonverbal. Language makes logic explicit. It reveals the inner workings of our mind. AIs have the capacity to interpret language and pattern inputs. This matters because any logical system is limited. It cannot prove its own axioms. It is based on some self-evident truths that we take for granted. Pattern recognition—language interpretation—allows us to inject additional truths into logical systems.

Language, the ability to communicate and share our experiences, the ability to have dialogue, is perhaps the key to sentience.

1 / 1How does the brain produce consciousness?

2 / 1Math in speech and nature of multiplicationI just found out that "It doesn't make no sense" is a multiplication of "not" and "no", as it implies a positive out of 2 negatives.
So I thought about this and I tried to grasp what multiplication really is.
>pic related is what I came up with
So basically I believe that "x times y" means "x under influence of y" or "x in the system of y".
Like my factory example in the pic.
But then I thought "Wait, isn't this factory basically what f(x) represents?

Then I tried thinking about it harder and untangle the cluster fuck in my brain but I'm reaching my IQ ceiling.

Can someone tell me where my mistake is?
What's the difference between a multiplication and a function?

9 / 0You didn't fall for the vector psyop did you, anon?

1 / 0What is matter?
>Matter is any substance that has mass and volume
What is mass?
>Mass is the quantity of matter in a volume

So matter is any substance that has a quantity of matter? That doesn't explain what matter is.

22 / 0Why not convert AC to DC outside of the house or neighborhood?wouldn't it save a lot in terms of AC-DC converters that are in 99% of electronics?

A typical 500 person neighborhood is less than 1 mile wide, or even 1/2 a mile wide.

500 people collectively have probably 3000 different gadgets that have ACDC converters.

Instead of that, you could have one big converter for the entire neighborhood, situated at the entrance, and all 500 people's electronics would be smaller and cheaper and produce less material waste. The entire neighborhood microgrid would run on DC. Isn't this feasible?

I'm sure it'd also be more energy efficient, because ensuring efficiency standards for one large public-service converter is way easier than ensuring efficiency standards for 3000 little things made for 50 cents in Indonesian factories

12 / 2What are some subjects to learn before you die?

0 / 0Let's talk esoteric, I mean some like real heterodox shit, ya know?

I want to know if anyone has ever tried to apply modal logic (a form of mathematical logic dealing with propositions about possibility and necessity) to the many worlds interpretation of quantum mechanics since both, of course, deal with the subject of alternative worlds.

Has anyone ever at least attempted to integrate the two from a legitimately rigorous perspective. I've always been fascinated by the idea of there being other worlds, other dimensions, a multi-verse, and my studies in math and logic have led me to some weird esoteric thoughts like this.

Even if just for hahas, please discuss.

7 / 0When will AI replace the soulless bugmen who sit around on Twitter/Reddit pounding their meat over AI? Given how intellectually unremarkable their midwit observations are, it seems that they should be among the first to be "replaced" if AI is worth the hype, so I've decided to use them as a canary in the coal mine for when I should start DOOM-PANICKING about losing my job.

9 / 1Scientifically speaking, what are the best hobbies for relaxation?

4 / 0Fractal superconductorsI have an idea involving Graphene and Yttrium Barium Copper Oxide (YBCO) arranged in a Penrose tiling fractal pattern at the nanoscale. If such a fractal superconductor were cooled to near absolute zero in a vacuum, could it produce unusual quantum effects—such as fractal vortex patterns, gapless states, or Casimir-like forces arising from zero-point energy in the aperiodic lattice?

This concept reminds me of quasicrystal superconductors (e.g., Al-Zn-Mg, Nature Communications, 2018) and phenomena like graphene’s Hofstadter butterfly.

Is there any possibility this approach could access effects at or near the Planck length scale (~10-35 meters), potentially relating to quantum gravity?

Has anyone encountered research on fractal superconductors or similar theories? I would appreciate references or insights.

29 / 3What are animals actually doing on a daily basis? Yes I know: foraging, grooming, playing, mating, nesting, sleeping and such. But really now: they seem to be repeatedly switching between these modes with lots of idle time in between when they just look around and move around a little bit until they get into one of these modes again.

Now this strikes me as quite odd because I would expect more efficient and goal oriented behavior but they seem to just wander around like NPC's until they get into the mood to do something specific again. Is it their brains? Is it because humans limited their environment? Is this some kind of evolutionary optimum?

Anyway: contrary to popular belief cats specifically do not seem to follow buddhist teachings. One moment they want to rest and the next they get up again so they're quite restless and easily distracted.

13 / 1Funny how humanity spent centuries thinking wars, torture, and public executions were “normal.”
Burning villages for power? Ethical. Tearing people apart in public squares? Ethical.

But the moment someone suggests using science to eliminate genetic diseases or create an organism that never gets sick — suddenly it’s “immoral” and “forbidden.”

Maybe the problem isn’t that ethics protects us… maybe ethics has always been a convenient excuse to protect the status quo.

Fear of the new has always been the biggest brake on progress. Electricity was “the devil’s work,” antibiotics were “dangerous,” now genetic engineering is the new “taboo.”

This will never change until we stop treating “ethics” as a sacred dogma and start rebuilding it from scratch

9 / 1I couldn't get rid of my subdermal fungal infection on my forehead, nothing worked, so I decided to stick my head inside an Acoustic Levitator (the machines the levitate frogs in and such) and afterward my skin was red and I had a headache because the vibrations went all the way through my head but afterward all the fungus cells were dead and went away.

6 / 1If you live in a first world country, do you really need to live an enviornmentally conscious lifestyle? I feel like meme advice from school like don't waste food, don't waste water, don't burn paper are solutions to problems only found in developing countries with burgeoning populations that are just starting to industrialize.

5 / 1I haven't been able to focus on or absorb written information since COVID. It's like I got some kind of ministroke and turned dyslexic, its so horrible. You know those retarded normies who's eyes glass over when they have to focus on and digest a structurally complex idea for more than 15 seconds? The ones who find reading boring or tiring? I feel like I'm turning into one of those people and I hate it. I just feel so mentally discombobulated and reading and absorbing information feels like an effort now. It wasn't always like this, just ever since COVID

11 / 1MU-CFT vs Einstein: singularities goneIn GR, the Schwarzschild–de Sitter metric diverges at r=0 singularity.

In my MU-CFT paper "Comparison of MU-CFT and General Relativity: Coherent vs Classical Gravity", I introduce a coherence-based modification:

f_coh(r) = 1 − 2Mr / (r^2 + ε^2) + (λ/6) r^2 (1 − e^(−γr))

denominator r^2+ε^2 regularizes the core
exponential factor ensures smooth decay
no curvature blow-up at r=0

So GR gives singularities, MU-CFT gives a smooth metric.
No exotic matter, just a coherence term from the Lagrangian.

29 / 5What forms of gene editing do you expect to become available to the average person within the next half century or so? Designer babies? Editing of adults? What will they look like?
And how good will they be? For example, will they be able to ensure your child will grow up to be smart, attractive, and athletic simultaneously, or will they merely be able to take out certain deleterious genes like those associated with autism and dwarfism to give your child a better shot at the genetic lottery?

20 / 1Explain to me intuitively why a curved spacetime causes gravity>Geodesics
Sure, but why would an object move on the geodesic and accelerate, why cant something stay still?
I flat space objects can either move in straight lines, kind of geodesics, or just stay still.

9 / 0A Theory of Everything Integrating ConsciousnessMU-CFT (Mandrov Unified Coherent Field Theory) is a theoretical framework uniting quantum physics, gravity, information, and observer dynamics into a coherent whole. Reality, in this approach, is not an objective absolute but emerges through structured subjective coherence.

This theory explores how conscious observers influence physical law through coherence — a principle that selects stable, consistent, and meaningful branches of possibility.

Currently have a bunch of Acacia Maidnii and was thinking of hybridizing them with Acacia Floribunda for higher Alkaloid extraction and survivability, would that be a good move?
Floribunda = 0.3% DMT in leaf, NMT
Maidenii = 0.24% of N-methyltryptamine and 0.36% DMT

5 / 0Einstein Pseudo-TensorSo there's a problem in general relativity that has me a bit confused; some history is needed to explain it though.

So in the long, long ago there were two people in a fierce race to develop the field equations that would make up the mathematical foundations of general relativity, that being Albert Einstein and David Hilbert. Now it is a matter of debate who actually got to the field equations first (my bets are on Hilbert), but that's beside the point. See, there was a fundamental difference between how these two juggernauts actually derived their equations that makes me really second-guess energy in a "gravitational field". Hilbert's formulation doesn't really have this problem, since he derives the equations from an action principle. But Einstein's formulation includes this term here: [math]t_{ab}[/math], a term that is supposed to represent the energy of the field. This is a pseudo-tensor, meaning that once Einstein chose his coordinates, it vanished, and he didn't really need to concern himself with it.

Now the problem I have with what Einstein has done here is two-fold:

1. Where the fuck does this term even come from, and why does he need to use it?

2. One is a bit more intense, so I'll just link this video: https://www.youtube.com/watch?v=0CSL702JSdY&t

Now I'm way too dense to understand what this guy is alluding to (like I barely got past uni) so fuck if I know. But this kinda looks like a contradiction. I don't believe this invalidates general relativity like this guy says, since you can go the Hilbert way and use an action, and I think Noether's Theorem can help unfuck the situation a bit. But it still looks like a problem, so can someone elaborate on how this guy is either totally correct or totally full of shit? (The main contradiction he talks about happens at around the 14:30 timestamp).

* Are we a few angles here or do you believe in responsobility?

However, you can go or close thw thread if you find it disturbing.

Medfags, doctors (wont be), and other anons who know abt this...

Is the Carotid Artery the fastes and safest way to go if you can go full Seppukku for 5 minutes max?

1. Ive heard about people who survived a 100ft fall even 300 meteres which is a lot. Thats almost 1/3th of a kilometer which is 1.6 times less than a mile. Ive heard lots of horror about falling from that height. Breathing and staying in coma for 3 months and than dying etc.

2. Ive heard that thw well known poisons out of nature (wont share details) sometimes leave you paralized. Its a bit of a risk..

3. From an European non-gunz county but there is little change to create myself gun but its one of the lasts options

4. Long story shorter: the Carotid will dp the job in a few minutes IF you cut it quite deep? Does it help to take oxycodone at front? Ive got 8 oxy pills left: what are my changes?

Yes in afraid for trains and jumping since ive heard that people eother suffer for hours or survive it at rates above 30%

Sepukku or the carotid artery. Not afraid of suffering if it goes quick.

33 / 3Field extension from reals to hyperreals.Given an irrational number 0.d..., where d is variable, can anything be specified about the hyperreal part of that number? This was the only provocative question in the last number representation thread and it deserves a second round of abuse. How would you write it? Just 0.d...;... with an empty part? If so, are irrational hyperreals "shorter" in some sense than rational hyperreals?

21 / 3Are we in end times?

94 / 9I have a theory of motion inspired by the double slit experiments, which show that the trajectory a photon takes depends on how we measure it (which-way experiments). Suppose there was a spacecraft with the ability to cloak itself perfectly such that it would become invisible to external observers. In the cloaked state, this spacecraft must be in a state of “superposition” — its spatial position can only be defined by the internal observer’s measurement. Suppose our spaceship, before cloaking, picks up a light signal like a radio telescope, from its desired destination, and transforms it into an image of that distant location. Then the spaceship activates the cloak, hiding itself from external observers, and projects the reconstructed image of its destination into its surface. Upon decloaking, I hypothesize that the ship should already have arrived. In physics jargon this is referred to, I believe, as “modifying the boundary conditions”.

I have an LLM generated paper that formally outlines this theory, proposes a tabletop optics experiment, and shows the mathematical derivation. Whether it’s “mine” or not doesn’t even matter to me anymore. I just want to know the truth.

99 / 10The physics of 9/11>passport found
>engine found
>Betty Ong's remains found
This is because when an explosion happens it blows shit in the opposite direction. If it just "vaporized everything" we wouldn't ne here (refer to the Big Bang).
>why did WTC7 collapse?
Because of fire
It heated up on 10 floors, with uncontrolled ones on 6 of thdm for hours which lead the girders to thermally expand, leading to the failure of a key support column, thus facilitating a fire collapse.
>fire doesn't collapse things!
Whaf the fuck is a flashover?
>how did it happen when other buildings withstood fires for much longer?
Because it was some experimental design from the 1960s.
>those terrorists didn't know how to fly!
You're right. Which is why NORAD couldn't detecf them soon enough because they kept going up and down.
>jet fuel can't melt steel beams
You're right, but it can weakene it to the point of structural failure. Which is why it collapsed, due to the trusses and floors sagging and the top of the building no longer being able to support the weight. So the top of the building tilted and crushed the rest of the floors underneath it at near freefall speed. But the difference is the collapse was more outwards rather than inwards, which is why the concrete inner cores were left intact 10-15 seconds after both collapses before they too crumbled and fell due to no longer having support.
>the black smoke meant the fires were oxygen starved
This is wrong on two counts: plastics were burning which is why the smoke was thick, oily and black, and the fireproofing was dislodged due to the impact. Also, is this why 200 people jumped to their deaths?
>but it was meant to withstand plane impacts
Not going at the speed of a .45 caliber bullet that's the size of a fucking Boeing commercial jet.
>aluminum is too weak to penetrate steel
You're right. That's why the explosion and impact dislodged bolts and unsheared shit leaving a crater that didn't fully enter it.

14 / 1Is pattern recognition evolution in humans one of the reasons why conspiracy theories & extreme political ideologies and something related like say racism runs so harshly rampant in (otherwise) civilized communities nowadays? If I see nothing but impoverished blacks on the news committing crimes or chemtrails in the sky every time I go outside and happen to observe a weather forecast associated with said phenomena and associate the two together, am I really just letting my monke brain's desire to survive and keep living influence my decision making and thoughts based on those facts alone?
>No shit sherlock how do you think Gurg knew not to eat poison berries or run away from the sight of wild man-eating bears
Yes I know but at some point its gotta be counterintuitive right? Even if it sorta makes sense on paper, If it looks,swims & quacks like a duck, yes. But I'm not about to sit here and just call anything that has a bill, lays eggs and swims a duck, it could be a Platypus or whatever other waterfowl fit the bill.
As well as we evolved to recognize patterns and infer surface information based on those initial & repeated observations, there's gotta be like some downside or something right? Am I reading too hard into this?
Am I retarded?

8 / 0Does this make sense?

0 / 0So I was thinking about the speed of light and gravity and it occurred to me that doesn't everything make a lot more sense when you think of time as being the fundamental constant in the universe?

Like consider that we're moving through time at a constant speed and everything is being dragged through time, objects with no mass move at the same speed as time, which is just the speed of light (time), objects with mass move at some fraction of that speed and those objects experience drag when moving through time which is just gravity.

If you then think about objects like black holes these are too heavy for time to move they just sink into the fabric of time and they don't move through time, and it's known that at the edge of a black hole time stands still.

This also intuitively explains why you can't go faster than the speed of light because that's the maximum speed of an uninhibited object, to go faster than light you would have to have less mass than something with no mass which isn't possible which explains why people say you need negative mess for FTL travel.

In short mass resists time’s flow, and gravity is the result of that resistance. Or so I think, can someone explain why I'm wrong, because to me it seems like all the fundamentals still hold up when you look at things this way and it seems much easier to understand intuitively. Time is just a river and we're all moving along with it at the same flow.

21 / 1When new systems evolve, how do all the supporting systems also evolve at the exact same time?

Like when all the bones that make up the ear stopped rattling around inside our ancestor's jaw and finally formed a fully working hammer/anvil/stirrup ear system, how did the nerve connections and the bloodway connections and the new brain systems and connections to process the new input signal all evolve at the exact same time to support that? And the hairs and the fluid and the self cleaning and everything else that's all inside your ear.

I struggle with this part.

0 / 0Combinatorics for a retarded physicistLong story short I need to git gud at counting for statistical mechanics and I was hoping to discuss some issues.

First off, it makes perfect sense that if I have a [math]2*D*N[/math] - tuple for [math]N[/math] particles in [math]D[/math] dimensions then a macrostate is a collection of those tuples.

If we can have [math]\Omega_{r}[/math] different ways of organizing the spatial arrangements and [math]\Omega_{v}[/math] ways to organize the velocity arrangements after energy and volume constraints then it makes sense that [math]\Omega = \Omega_{r} * \Omega_{v}[/math] is the total number of configs for the system, so I can use some funny statistics for the velocity distribution to get [math] \Omega_{v} [/math] but counting [math] \Omega_{r}[/math] is always a pain in the ass for me.

Are there any book recs for counting shit like we do in statistical mechanics? I don't wanna get filtered by literal kindergarten counting.

I made this like two years ago when I was deeply researching the subject and figured I should post this shit somewhere publicly. I’ll probably post it elsewhere as well. It’s not well formatted or organized, it doesn’t include absolutely everything I’ve seen, some of my explanations might not be totally right, and I think some of the links are messed up but I don’t feel like fixing any of that shit now. And regardless of all that this is still the most thorough assemblage of information on the topic I’ve seen anywhere. I’ll probably update it at some point in the future. And if you have any opinions of critiques of my stuff I don’t really care because I’ve already formed my opinions on this subject and am not going to change them because of some slander on a decaying anonymous image board.

5 / 1What can a dumb person like me use Python for in trying to cure aging scientifically that has nothing to do with diet, exercise, and sleep?

22 / 1Business idea: someone should make a YouTube video series called something like "AI vs. Expert", where an AI was asked questions from some field of tech, science etc., and an expert of the respective field would then critique the AI's answers and assess it's level of understanding of the subject. Maybe some answers would be correct, while some would be wildly inaccurate and the expert could then correct them and give their own answers to the questions. You could even use multiple different LLMs and have the expert rank them. I bet the videos would be pretty interesting and they would do great numbers. The videos would be somewhat easy to produce too.

11 / 0Personal Project - Internally Consistent WorldFirst time posting on here, so excuse the clumsy nature of this thread.

I've been pretty unsatisfied with how bare bones and downright vacant the Elemental Planes are in traditional Dungeons and Dragons. So I started writing my own additions, which has slowly ballooned out into a much bigger project. Adding not only new locations, but also biomes, creatures, cultures, and ways of life.

In short, aside from showing off what I have so far, I need help. I've pretty much exhausted my pool of knowledge and inspiration and I'm far from done. So I'm throwing my net into this ocean hoping to get new perspectives and ideas that I wouldn't have on my own. I don't just want to make something up just for the hell of it, I want to make something that feels cohesive and plausible given the fantastical elements. Math, Science, History, Obscure Mechanics, One Off Ideas - I want it all.

If any of this sounds interesting, please take a look. Over 40k works split over the Planes of Fire, Air, and Water.

6 / 0The Science of Brazilian Fart PornI need the help of the experts on /sci/. I recently watched a Brazilian fart fetish pornography film and I was struck by the sheer volume of farts these women can put out. What I want to understand is how this is biologically possible. Let me lay out some facts for you:
>average video is 20-30 minutes
>woman farts semi-powerfully on average every 30 seconds (usually into another woman's face), consistently
>thousands of videos from this studio
>thousands of models
>most are amateurs or first-timers, so they are not "professional farters"

Whatever this porn studio is doing to get this consistency of farting from these women has to be easy enough and routinizable enough that they can take a random 19 year old Brazilian Instagram model, prep her for a shoot, and get 20-30 minutes of rapid farting with no breaks and no sharts.

I don't understand how this is possible. I figure they have a dietary regimen they subject the women to, and I wonder whether they inject air into the woman's colon before the shoot. Is anyone on /sci/ a farting expert? This is not a joke post. I want to understand how they can do this with such consistency as a business model. I could not fart this consistently if you paid me. Pic unrelated.
