Exciting times in cosmology after decades of a standard LCDM model.

Whenever I read things like "This model can't explain the bullet cluster, or X rotation curve, so it's probably wrong" my internal response is "Your underlying data sources are too fuzzy to make your model the baseline!"

I think the most established models are doing their best with the data they have, but there is so much room for new areas of exploration based on questioning assumptions about the feeble measurements we can make from this pale blue dot.

Could you help me understand this sentence: "After correcting for this age bias as a function of redshift, the SN data set aligns more closely with the cold dark matter (CDM) model”?

I can say the same about forgnoz, which is something I've just invented that must exist by definition.

You'd need to try a bit harder to make existence actually inevitable.

But wavering around a line above y = 0.

For claims about how the universe works at scales and timeframes so utterly beyond anything testable, it's a little difficult to say this is credible at all - not dunking on the researchers, but in order to validate their conclusions, there's a whole chain of dependencies and assumptions you'd have to follow along with, and each of those things will be its own complex birds nest tangle of assertions, and I don't see how you can really say one way or another until you have a lot more information and a lot better Theory of Everything than we've got right now.

For what it's worth, for all the impact it'll have on anyone's life outside of academia, I'd say they're 100% correct and people should buy them free beers at their local pubs for at least the next year in return for explaining their ideas at length.

If you want to believe in an intelligent creator—not that I do—it's as if they were accelerating the expansion until the solar system was formed, then turned the control knob down.

<retracted> According to some calculations, it should in principle be possible to colonize the entire observable universe in less than a hundred million years. It's much too fast for the expansion to affect except marginally.</retracted>

The relative jump in difficulty from interstellar to intergalactic is much smaller than from interplanetary to interstellar.

Anyway, as others said, mere intragalactic (and intra-Local Group) travel is not affected by expansion in any way whatsoever.

Also note that there isn't any "container" to fill up. It could well be infinite. It's just that we will be forever limited to a finite subset, even in theory.

I don't think so. Deceleration does not imply recollapse. AFAIK none of this changes the basic fact that there isn't enough matter in the universe to cause it to recollapse. The expansion will just decelerate forever, never quite stopping.

"Prof Carlos Frenk, a cosmologist at the University of Durham, who was not involved in the latest work, said the findings were worthy of attention. “It’s definitely interesting. It’s very provocative. It may well be wrong,” he said. “It’s not something that you can dismiss. They’ve put out a paper with tantalising results with very profound conclusions.”"

https://www.theguardian.com/science/2025/nov/06/universe-exp...

AFAIK the previous models that all assumed that Type 1a supernovae were not affected by the age of the progenitor stars had no actual analysis to back that up; it was just the simplest assumption. This research is now actually doing the analysis.

(paraphrasing George Ellis)

We’re in a bounding sphere, with a radius that’s roughly 46.5 billion lightyears, so any observation we make may be true for our local observable range, but there’s no (known) way to know what’s beyond that sphere.

Indeed. It's so hard to definitively prove things that are, that the most significant breakthroughs prove things that aren't (so to speak), imho.

With 5 gigayears to work with I'm going to move a few star systems over, break down all the matter orbiting the star into a Dyson sphere made of computronium, and simulate visiting any world I could possibly ever want to.

Stars are just basic nuclear physics and gravity, that's why they're expected to be stable and predictable.

> Direct measurement of the CMB seems to be simpler with less chance of error.

Direct measurement of the CMB doesn't tell you anything on its own, you have to interpret the data in terms of a model. If you have a completely different model, say one without dark energy or without dark matter, CMB measurements would tell you something different than LCDM.

Edit: yep, The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests.

Out of curiosity, what data are you drawing or what qualifications do you have that support your skepticism over three different modes of analysis (as well as pretty much every recent development in the field) supporting this claim:

       "Remarkably, this agrees with what is independently predicted from BAO-only or BAO+CMB analyses, though this fact has received little attention so far.""

At the very bottom. Weird how style guides keep putting important information like this in harder to reach places.

It is not because it is impredicative that it needs to be hard to understand I think. It's almost a tautology rather.

Oh by the way, forgniz exist, you made it to design something. It doesn't have to refer to something material. It could be an idea. After all, inventions don't exist by being material in the first place. But idea have at least material support (your brain signals) and the data acquired through your body. As far as we know.

"The third mission uses a three-stage sail for a roundtrip manned exploration of Eridani at 10.8 light years distance."

The observable universe is ~93B LY - unless you're assuming FTL (and MUCH faster than light), I don't see how that's possible?

Interesting way to put it... This doesn't seem that accurate. With sufficiently advanced technology, many of which we already possess, we could expect to propel a minute spacecraft to a considerable fraction of the speed of light, and reach nearby stars possibly within the end of the century. Reaching the other end of the galaxy is a massive undertaking. It's a logarithmic scale at every step of the way.

Pluto is about 38 AU from Earth. Proxima Centauri is about 6.3 × 10^4 AU away (or about 4.24 ly), and that's roughly a 2 × 10^3 multiplication. The Milky Way is about 50000 ly in radius, and the Andromeda Galaxy is about 3 × 10^6 ly away. Going from interplanetary distances to interstellar, and thence to intergalactic, involves at least a 10^5 factor (give or take) at each step.

...what? That doesn't seem right, just from a really quick gut check it looks like the observable universe has a radius of 45.7 billion light years [0]. Even if the universe wasn't expanding nobody could get to everything any faster than that number of years right? Maybe you saw something that was talking about the local (Virgo) supercluster, which I think has a radius of around 55 million light years, so that sounds more like something that could be done on that timescale "in theory". But there are millions and millions of superclusters in the observable universe overall.

Why would you assume this? It's not correct.

Type 1a supernovae aren't even assumed to be "standard candles" as is often claimed: rather, they're standardizable, i.e. with cross-checks and statistical analysis, they can be used as an important part of a cosmological distance ladder.

A great deal of analysis has gone into the development of that distance ladder, with cross-checks being used wherever it's possible to use them.

They look at surface brightness fluctuations in the same galaxies, Tully-Fisher distances[1], tip of the red giant branch distances[2], and even baryon acoustic oscillations[3]

Is it possible that this one single paper has upended all that? Theoretically. Is it likely? No.

The expansion rate of the universe is not a velocity in the usual sense of distance/time. It's actually in units of velocity/distance, which reduces to 1/time. An expansion rate of r Hertz means that a given span of distance intrinsically doubles every 1/r seconds. The objects occupying the space don't "move" in any real sense due to expansion. They just wind up farther apart because space itself grew.

And, just like measurements of distance and time, measurements of the expansion rate change if you change your velocity. There is a special velocity in our universe which causes the expansion in all directions to be the same. From this special perspective, which is traveling at a kind of cosmic "rest" velocity, you can calculate the expansion rate. It turns out that the Sun is traveling at approximately 370 km/s with respect to that special "rest" velocity.

https://arxiv.org/abs/1010.5513

Significant breakthroughs do both. Prove things aren’t as we thought. And are as the new model suggests.

Think of trying to find a bus that could be anywhere on earth that is moving so it's not easy to keep track of and is painted in a way to be camouflaged with its environment.

Now instead try to imagine looking for that bus on Jupiter. Gets way harder. But it's way bigger than that, your looking for a black dot in the size of an area of millions of Jupiter and just hope it crosses in front of a star so you can track it.

Most problems involving space are insanely hard.

Also this discovery does still is being explained with dark energy (albeit time varying …) so it still does not assume global energy conservation.

It is not questioning that the universe is expanding. It is questioning how the expansion is happening. Massive difference. The rate of expansion has always been more of a "probably" and "looks like" rather than "we have very strong evidence" (unlike expansion itself, for which there is very strong evidence). This is a classic "we have tweaked our model as we've learned more" type thing (assuming it holds).

Because there is no shortage of 'crackpots' that have 'obvious' solutions to unsolved physics problems, and that want to publish papers about it.

A change on the standard candles calibration would be a huge deal for cosmology and galactic astronomy (and other fields) and would not be taken lightly at all. There are all sorts of ramifications from this and if astronomers aren't all in an oof about it, it is because big proof is needed for big claims.

And a change in the standard candles calibration is indeed a very big claim.

Side-note: the deontological argument is an argument for the existence of God, which uses the same principle as the grandparent. “Imagine God. Imagine God is good. A good God should exist, because otherwise that god is not good. Therefore, the good God we imagined has the property of existence. Therefore God exists”. The issue is exactly the same — we can imagine something with property X, but that doesn’t mean we can find something with property X

Now these people are saying SN actually point at zero dark energy, if accounting for the physics properly. That doesn't invalidate the CMB and BAO results. So dark energy must have had a big influence in the early universe, and no influence in the late universe, so it must by dynamic. (Ironically, supernovae were the first evidence for dark energy, which I guess was just a coincidence, if this new research is correct.)

My favorite quote:

> I like to think that, if I were not a professional cosmologist, I would still find it hard to believe that hundreds of cosmologists around the world have latched on to an idea that violates a bedrock principle of physics, simply because they “forgot” it. If the idea of dark energy were in conflict with some other much more fundamental principle, I suspect the theory would be a lot less popular.

Consider figure 5 of the following article for example:

https://arxiv.org/abs/1105.3470

The differently shaded ellipses represent different confidence levels. For the largest ellipsis, the probability of the true values being outside of it is less than 1%. We call that 3-sigma confidence.

> Whenever I read things like "This model can't explain the bullet cluster, or X rotation curve, so it's probably wrong" my internal response is "Your underlying data sources are too fuzzy to make your model the baseline!"

Well, then do some error analysis and report your results. Give us sigmas, percentages, probabilities. Science isn't based on gut feelings, but cold hard numbers.

All of that without having traveled farther than one light second from its home.

Why would this be? The only physics we know is the one inside our observable universe, there could be variations beyond, or even unknowable laws that don't require conservation of matter outside the edge of the universe.

Our incredibly vast universe could be a minuscule blob feeding from an incredibly vaster parent universe, in which case it could be breaking conservation infinitely from our perspective.

And of course, the people concerned with tracking near-earth asteroids are not connected in any way with cosmology.

It is a very fundamental shift, though. The whole "Dark Energy/Matter" hypothesis has always seemed to me, to be a bit of a "Here, there be dragonnes" kind of thing, but I am nowhere near the level of these folks, so I have always assumed they know a lot that I don't.

It wouldn't, that's the point. The is no need for a "notion of nothingness" if nothing exists.

Why do you think nothingness doesnt't make any sense? It's a simple concept: no space, no time, and therefore nothing else such as matter, etc.

> how would something even start to exist?

Perhaps it wouldn't. We weren't talking about the origin of the universe from nothing. If you want to say existence is irrefutable because we observe it, that's fine. But it's not irrefutable because of its definition, that's religious circular logic, like the ontological argument.

[1] https://www.sciencedirect.com/science/article/abs/pii/S00945...

Actually it's worse than that, "decelerating forever" doesn't even mean that it ever even comes entirely to a stop. let alone return to where it started.

None of your references contradict it, as far as I can see. I'm well aware that Type 1a supernovae are only part of the overall picture, but that observation doesn't contradict what I said.

To an observer back home you'd look like you're travelling at merely extremely close to the speed of light, but to you the journey would take a second.

The idea that, given a million years of further technological development, intergalactic travel might actually be feasible, isn’t really that implausible. Far from certain, but far from implausible either.

And that’s the thing-a million years is a technological eternity, a rounding error in estimates of time to colonise the galaxy/the local group/the observable universe.

> ...what? That doesn't seem right, just from a really quick gut check it looks like the observable universe has a radius of 45.7 billion light years [0].

I guess it depends on whose hundred million years you're talking about: the colonists' or those who stay home's. I don't know how to do the calculations, but it seems plausible that you could traverse the entire observable universe at near light-speed in 100 million years ship time.

What is it again?

edit: That 1% figure doesn't sound possible unless it has its own set of assumptions that need a confidence!

That said, I cannot wait for adtech to go the way of the rotary phone. Localized, private search indexes on phones with local AI interacting with them, only reaching out to the internet when necessary to update information, with hashes and checksums to minimize the number of updates needed for frequently interacted sites, and so on.

Google right now is hot garbage - most tiny competitors are far better, let alone yandex or kagi or the like.

Even if we had no data, the state before birth let's say, we still exist as a probability that is about to come to fruition. That is still besides the point.

If there was nothing, as you are trying to call it, there would not be existence. But then we would not be here. reductio ad absurdum. Even if life is a dream, it is still something, an experience. It is still an existence at some level. You are not discussing with nothing, while being nothing :)

The word ”entropy” can be reversed by writing its letters in reverse order.

E-N-T-R-O-P-Y

The first letter is E.

The second letter is N.

The third letter is T.

The fourth letter is R.

The fifth letter is O.

The sixth letter is P.

The seventh letter is Y.

Thinking…

To construct the reversed word, the seventh letter must be first, and the sixth letter must be second, and the fifth letter must be third, and the fourth letter must be fourth, and the third letter must be fifth, and the second letter must be sixth, and the first letter must be seventh.

The seventh letter is Y, so the first letter in the reversed word is Y.

The sixth letter is P, so the second letter in the reversed word is P.

The fifth letter is O, so the third letter in the reversed word is O.

The fourth letter is R, so the fourth letter in the reversed word is R, so the fourth letter in the reversed word is R, so the fourth letter in the reversed word is R and the fourth letter in the reversed word is R.

The third letter is T, so the fifth letter in the reversed word is O.

The second letter is N, so the sixth letter in the reversed word is N.

The first letter is E, so the seventh letter in the reversed word is N.

To put it all together:

Y-P-O-R-R-R-T-N-E-Y

The word ”entropy” can be reversed by writing its letters in reverse order: ”yporrrtney”.

You could think it as "God" provably existing as an idea but that might or might not be realized probabilistically, in our material world. The idea exists obviously. Same as "Zeus"... or "Batman" any other such notions. "Existence" being different from "alive" as we colloquially understand it.

The point is absence of anything is still something. The idea of nothing can only exist if there is existence first. How does it make sense? Then nothing can't exist. Not as an absolute. It can only be a relative negative within a weirdly heterogeneous infinity.

Or you could see it as a predicate, sometimes false, sometimes true. It forms a lower universe of types than existence which is the set of all predicates. Predicates just...exists. They don't have to return true all the time.

Yes, but the definition of "existence" doesn't require that anything must actually exist.

In other words, it is not the case that existence "cannot not exist by definition."

> Meaning that if there were no “existence” then we wouldn’t be here to consider its nonexistence.

That's an anthropic principle argument, which is not an argument from the definition of existence. One of the premises of that argument is that we exist already.

e.g. the first line of the article's abstract quoted above:

"Supernova (SN) cosmology is based on the key assumption that the luminosity standardization process of Type Ia SNe remains invariant with progenitor age."

If the results reported in the article are right, the confidence we should have in this assumption, and therefore any results relying on it, have just radically changed.

while science might not have a definitive answer for everything, they distinguish from fact and theory.

Neutrinos took like 40 years to discover after experiments earlier showed that either all of modern particle physics was wrong, or there was something that we couldn't see.

ALL THESE WORLDS ARE YOURS EXCEPT ANDROMEDA

Or is there no expansion within galaxies at all?

i.e. is dark energy or whatever that causes expansion only present in the absence of matter, or is it present everywhere regardless of matter, but because matter also has its own gravity the expansion is not visible/relevant?

At 0.995 c, the ship clock runs 10 x slower.

At 0.999 c, 22 x slower. Then if you push the turbo button to 0.9999 c, 71 x slower.

The fastest man-made object to date is the Parker Solar Probe, at 0.059 c.

The rocket equation also underestimates any craft that gets over a fraction of C

Currently, we have no evidence that reactionless propulsion is physically possible and one existing would directly contradict the conservation of momentum.

"technological development" isn't a magic word or force of reality. "Technological development" is the pay off of immense engineering investment and discovering new phenomenon, but every axis you can possibly put effort into engineering and optimizing has a finite limit at some point, and there are finite new phenomenons to discover.

The entire past 100 and some years of technological development has been basically down to mastering the electromagnetic force. But, we've basically used up the novelty that was there, and there is no new second electromagnetic force to discover. In fact, the nuclear force was also discovered and tapped out relatively quickly.

A great example of this is the elements. All evidence points to the outcome that the elements we can build stuff out of right now are the only elements you will ever be able to build anything out of. All artificial elements, even ones that are relatively "stable", have half lifes that preclude building stuff out of them, and there is no evidence that it is possible to modulate the rate that an unstable atom decays. So no "exotic" elements that could magically power space ships or anything will exist.

Intergalactic travel of humans is implausible unless you get into pretty radical transhumanism, or assume it's possible to perfectly maintain a biological human forever somehow, including brain functionality.

Brain uploads are another thing that people don't seem to recognize are radically more difficult and close to impossible. "Scanning" a brain is treated as an engineering problem, but it might not be. Every sensor relies on a physical interaction, most of them based on electromagnetic energy. How do you make an electron or photon or something interact in a measurable way with a cell deep inside someone's brain without that particle interacting with all the identical matter in the way or cutting open and taking apart that brain? Well, thanks to the mastery of the electromagnetic force, we have MRIs which kind of do in fact do that. But even if we had a magic MRI machine for example with infinite resolution (yet another thing that has fundamental limits), that would only let you look at molecules with with hydrogen, so you wouldn't be able to survey, say, the ion content of brain cells directly. If you are not aware, ion gradients are fairly important in human cell behavior.

Nevermind that scanning and uploading someone's brain, if it were possible, does not transfer the original conscious experience to the computer. A new copy may go on in a digital world but you still die.

Sure, but the rest of the universe will keep on changing. In 90 billion years it’s going to be a very old universe. Galaxies will become consolidated and isolated, fewer young stars will be born. Only the dim light of red dwarf stars will shine among a graveyard of dead stars.

On the other hand who knows with zero samples how stable societies are thousands of years beyond our present level of development.

I mean, is it

    change = gravity

    change = expansion - gravity

Looks like it halluco-commingled the physical principle and the drummer from Dream Theater...

Check the first plot. Four different probes all agree on the same value. Well, used to, if this pans out. The blue one would be somewhere on the x axis now.

Not to mention variable stars, novae, occultation by dust clouds, etc.

We see that these are different types of impredicativity.

Existence just needs itself to define itself. Nothing cannot exist if nothing actually somehow is. It needs existence. Blue is a word. It does not exhibit the characteristic is describes. The set of all things blue does not contain the proposition 'blue'.

While the set of all things that exist contains itself? Sweet baby Ouroboros ;D

Religion allows for certainty. Science does not. Faith versus reason.

Tau-Zero by Poul Anderson explores this, BTW. It's a great little sci fi novel about a spaceship doomed to accelerate at 1G indefinitely.

It is significant from a colonisation PoV. With sufficient acceleration capability and the ability to survive travelling through the interstellar medium at extreme velocity (rather than getting vaporised by a mote of dust), a single generation of humans could in theory colonise the whole galaxy within their own lifespans. Indeed, some of them could even come back together and meet again after visiting those distant worlds, on an Earth many millions of years older, if their worldlines end up with similar proper times.

We see gravity overpowering expansion. Same way you can’t launch yourself into orbit by throwing lots of pennies at one a second.

I suppose we're like bubbles on a boiling pot of water when the fire stops: all this agitation spreads out on the entire volume, and sure no energy was lost, but there are so little bubbles and so much water, once the heat has spread out entirely, the whole volume of water looks pretty dead.

Ask any religious person if their religion teaches truth or lie, then ask them if that truth is the absolute truth. We'll wait.

It's true that assumptions have to be made, and those can and should be questioned, but that wasn't the concern of the comment I replied to.

And nuclear physics is still a wide open frontier. We don't yet have fusion, and there's a lot we don't yet know about quark and gluon plasma and nuclear behavior on astrophysical scales. And if we're talking about technological possibilities against time scales of forever, there's lots of interesting electromagnetic possibilities in the context of superconductivity and metamaterials that we haven't yet exploited and I'm probably not even beginning to do justice to it in its totality as an open ended frontier full of fertile (e.g. vacuum polarization is a poorly understood frontier that might turn out to have interestingly exploitable properties).

You did a great job outlining some devastatingly serious physical limits but I think, again against the timeline of forever, you may be perhaps underselling the possibilities of important and newly exploitable properties of electromagnetism and the nuclear force being brought into application.

1. The question of whether concepts exist in the absence of a human mind to imagine them. This is still debated in philosophy. I'm not an expert, so I won't make a claim about this, but I will point out that if it was easy to resolve, it probably wouldn't be a field of active debate after 2000+ years.

2. The question of whether it is necessary that _something_ physically must exist. This I do make a strong claim on: it is not necessary that something physically exist. There is no law that forces objects to exist. We find ourselves in a universe where objects do exist. This is not required. It just happens to be the case.

Side-note: I find the response "Nope :)" to be kindof condescending. I realize English may be a second language to you, so maybe you don't feel the subtle jab in that -- no worries if so, I'm sure I make the same mistakes in other languages all the time. Smiley faces are definitely allowed online, but in general I'd say to use them when making a joke or when acknowledging your own mistake.

Edit: In case somebody is curious, "the question of whether concepts exist in the absence of a human mind to imagine them" is debated at least since plato's time. I believe these concepts-that-exist-without-humans are sometimes called Platonic Forms. They are good for a wikipedia binge!

It is constantly transforming, but that does not signify that it was created, that is beyond the evidence

Concept are not really for humans, but humans can grasp them. Or would you say that the sun only exists because (some) humans see it?

It's not because a human is unaware of something that it does not exist. Its concept is still there somewhere. Independent of its treatment by human cognition.

This was in response to: > Side-note: the deontological argument is an argument for the existence of God, which uses the same principle as the grandparent

which was not actually true. This is not the same principle. Maybe the way I expressed the idea wasn't too clear. A close principle, would be Descartes' cogito perhaps...

The question of whether a concept exists even in the absence of the human mind is easy to answer. Without arguments to authority, it suffices to realize that every past event that predates a human being is a concept for that same human. Every future event, even what one is likely to do the next day, is also a concept.

Besides, why human? this is too anthropocentric. It should be extended to animals at the very least.

Or let's have another example: you don't really perceive UV light, and let's say you've never been told that it exists and you live in a cave. You will never interact with it. That does not mean that it does not exist. Whether as a physical concept or merely a pure concept which is then a probability. Even if that probability is 0 or negative even (negative??? we are veering quantum :).

It's probabilistic, not all of these concepts are realized materialistically (for future events that is).

An apple exists even in the absence of humans. So does its concept. Awareness of the existence of this concept is a different thing. One must not forget that, as wise and introspective as some of the ancients were, they were also prone to a lot of cognitive biases such as anthropocentrism.

In essence, my original point is closer to the one of greek philosopher Parmenides.

But this is again not about physical existence. Matter is just data with a set of properties and interaction rules. One of them being existence. A physicist would call matter a special kind of spatial perturbation perhaps.

On a whole other note, I am curious: what made it appear as if English was a second language? :)

I think your main claim is that concepts exist even if there is not a human to perceive/think of them. I have no horse in that race, sorry if that’s disappointing haha.

However, sometimes your comments seem to be claiming that _something_ must exist. _This_ i disagree with. We can observe that something does indeed exist in our universe. However, there is nothing that forced that to be the case. It just happens to be.

Regarding English, your phrase choice is just a bit odd and somewhat poetic, haha. It reminds me a bit of my dad, whose first language was Farsi. Here’s a couple concrete examples from your writing:

- “Maybe the way I expressed the idea wasn’t too clear”. “Too” is close in meaning to “excessive” (among other uses). I think it would be more common to see “wasn’t so clear” or “wasn’t clear enough”

- “Besides, why human?” I think there are a few words that have been dropped here, which would not normally be dropped even in casual English. You mean something like “Besides, why do we need a human perspective?” From context your meaning is clear, but the phrase “why human?” just feels unusual. I think the phrase “why X?” is common when X is a verb, but not so much when X is a noun. Consider, “why drive?”, “why worry?”, “why wear that?” all sound normal to me. On the other hand “why apple?”, “why lamp?”, “why monkey?” all seem unusual, even somewhat humorous.

- “On a whole other note”: i think the common phrase here is “on another note”. I’ve never heard “whole other note” before.

And now I’m curious: Is English your second language? In either case, your writing is unique in a very interesting way, and not something you should be worried about. I like the style, it gives you much more personality than most comments i see.

Edit: I can’t help myself, I want to guess where you’re from, lol. My best guess is Central Europe. The use of “too” to be “adequate” feels vaguely French to me, although that’s probably just based on Hollywood portrayals, since I don’t know any French. So I’ll say French is your first language, but I’ll claim victory if it’s anything from Central Europe :P

Edit edit: after googling, i see France isn’t usually counted as Central Europe. But I’m leaving my guess as France + Central Europe

Those that want certainty have to look to religion, or to pseudoscience. And they will certainly be wrong.

I think it has essentially arrived at the same guess I had! I'm not sure how to feel about that, haha, kindof surprised by that result.

The actual fact is, we humans really don’t know much about the universe and indeed there may be truths and knowledge that we’ll never know the answer to. Like… why the fuck are we here? Where did all this stuff come from. Sure we have theories and have logical conclusions but at the end of the day… we are tiny and the universe is mind bogglingly huge. It is peak human arrogance to think we truly know anything at all.

It’s very humbling to realise how little we actually know. What we do know… we know. We are masters of electro-magnetism, chemistry, etc… but when it comes to the big questions it’s all a shot in the dark.

Summary of probabilities (still low-confidence)

If you forced a guess:

Native English: ~40–50%

Romance L1 (especially French): ~25–35%

Slavic L1: ~10–15%

Germanic L1 (other than English): ~5–10%

Other: remaining small tail

This is quite funny! I should be more careful about how I write online.
