I keep seeing versions of this post, which imply a bizarre misunderstanding of how we know the world.

Do people imagine that if we'd never observed galaxies or neutrinos or exoplanets or the cosmic microwave background, we could have *imagined* these things & that would be just as real?

Or that we've magically reached the point, just now, where we no longer need to observe the world?

I also have to point out that the most expensive space telescope (JWST) cost about $500 million/year. We spent 1000x that much on AI development in 2025.

Data collection is essential for discovery...and it's remarkably cheap compared to many other things we do routinely.

I've also seen smart people tie themselves into knots trying to defend the original claim.

"He just means big science is expensive."
"He just means that AI can help with data analysis."
"He just means that string theory is a dead end."

But that is not the claim, and the efforts to justify it only make the argument even stranger.

@coreyspowell well, for analysis of ever increasing amount of astronomical data, some kind of automation is needed anyway. So maybe it would be better use of AI, than all this chatbot nonsense.

The huge colliders are special case, that now there is AFAIK no special prediction in physics, which can be confirmed or falsified at higher energies. Somehow it is probably not the direction to find any new physics (which would be cool). Also the dark matter detectors are somehow infamous as spending huge amount of money for (predictably) finding nothing.

The situation in astronomy is very different and of course we need new telescopes and new ideas for telescopes. Lot of them would have to be placed in space, probably.

So, somehow the discussion "what next in science" makes sense, and I would not probably bet on particle colliders to be the right answer. Still, over-relying on LLM-líke AIs si ridiculous. Of course, science needs new (not necesarily "more") empirical data and also, for huge amounts of data, some automation to process them.

@xChaos @coreyspowell Astronomers have been using automated data systems for years and these work very well at finding patterns in data. These are not general programs but finally honed analysis software. The issue is, and always has been, to work out what you want to look for. This always needs human intervention and I doubt very much whether any LLM would contribute anything beyond what we put into it.

As you say new telescopes are needed but I would not rule out the wish for a new larger collider. There is still a lot of good science to be done at higher energies even without any new major findings. Although I suspect there are some things lurking out there....

In all cases the cost will be high but relative to the cost of all the weapons expanded in the last few weeks it's not that big.

What's next in science is always a problem when the question tries to pit one side of science against another. You simply have no idea where the next breakthrough comes from. My bet is somewhere in biology and brain science.

If it were me and here we are talking physics I would scrap all manned spaceflight and put that money into science missions and telescopes as well as basic science.

@SamanthaJaneSmith @coreyspowell I am fan of manned spaceflight, but maybe, the funding should be different from science. Manned spaceflight is more or less extrapolation of great voyages, mountain climbing, polar expeditions, and such. I would compare it rather with great sport events... excepts is too ambient (most of the time) and the risks are of different type then risks undertaken in sports, so the funding model of great sport events would not work. It attracts attention of few people and in different way.

The TV show paradigm is definitely more worth replacing, than science.

But when talking about understanding universe, both large and small... you know, I am not scientist, just huge fan of science and history of science, but on amateur basis. It is exciting to invent concepts about how the universe works and be able to do something new, based on these new concepts. Sometimes, save lives.

The intuition, that there may be more to learn when looking at night sky at higher and higher resolutions and more frequency bands, than by smashing particles together at higher and higher frequencies is maybe wrong, who knows.

Definitely, trying to guess things without any input data means doing pure math. You can construct mathematical objects without input data... but why?

There was this strange case of string theory in physics, which thrived even without predicting any observation or suggesting any experiment. No future collider would prove or disprove this. Some theories are too far off....

I feel like there are two major approaches in natural sciences: one is this belief, that if mathematical object is possible, it simply exists somewhere in nature (so we see all this spirals and ornaments in plants, and so on) and the second approach is statistical analysis of gathered data.

Human language is not mathematical object, but LLM AIs somehow treat it as if it was. I seriously doubt, that searching through "all possible conversations" can replace science...

@xChaos @coreyspowell Hi again. The problem with manned spaceflight is that it sucks out the funding from the science program and tbh it is not good value for money. It may be "adventurous" but is that what taxpayer money should be spent on? I think not.

So theories in science are only theories if they are testable otherwise you have beliefs. (this is why the existence of a "god" is a belief - it can't be proved). So progress in science relies on (a) theories that can predict observable data you can observe either now or in the future (b) data to test these theories on or develop new ones from. These go hand-in-hand. Either data or theory may start a new field of research.

So lots of people do construct theories based on mathematical constructs only. Some may become useful some may not. Not all mathematically possible objects can exist or do.

No, you intuition about looking in more detail or different bands is correct which I why I believe they will build more colliders.

Not sure you are right about string theory tbh. It was a candidate for the strong force but it didn't work - however, it did seem to open possibilities for gravity. So it was actually trying to explain a physical phenomena. It is still very much in the - not sure phase of whether this works - but do remember that it is trying to explain the fundamental nature of the world which is observable..... it did however seem to provide some help in some very esoteric ideas that have implications in the real world. But these are way beyond my understanding as I am not a particle physicist or string theorist.

@SamanthaJaneSmith @coreyspowell well, I don't generally want to argue. I am not really scientist, partly for dumb reasons, which I regret now, partly simply because the required decisions would be needed at age, when I was not ready for it, may it was about the era our country was going through... I was too much hypnotized by "informatics" taking over everything. It was the mindset, which finally resulted in current LLM bubble, RAMageddon, etc. But I did not have enough concentration and focus anyway. Who knows, what could I focus on, if there was no programming around.

But I am fan of basic research and scientific knowledge. The "manned spaceflight vs. science funding" is mostly artificial political dilemma, and it could be compared to competitive sports vs. availability of some sport activity for public. There can be synergies on many levels.

You could argue, that particle colliders suck funding from other fields of basic research. Sometimes you just bet on certain direction of research and sometimes you spend money finding nothing. Eg. manned spaceflight, while basically just publicity stunt, would be probably better investment, than some attempts on dark matter detection. Maybe better publicity stunt, than "please give us money, so we can find nothing and prove it". I mean, there are worse scams, but sometimes, finding nothing with high level of signifixanxe is not the best message for general public, while cool space selfie may be much better message  

I don't want to join the general speticism about physics, which may be even somehow encouraged by climate change deniers. There are some parts of physics, which can be locally tested and are well known and probably won't be disproved any time soon. But at the same time, I would definitely invest into fine tuning of technologies for storing energy, instead of building larger collider. Sorry. There are real technological needs with political consequences...

@xChaos @coreyspowell Oh I don't necessarily disagree I would rather spend money on social care for example. I was simply talking about space and particle physics. It is in the end as you say political, as is everything.

The problem is we never know where a breakthrough will come... And that means some kind of balance in the program both in science and technology. Sadly that is not how it works.

@SamanthaJaneSmith @coreyspowell I believe some great discoveries were made ... by mistake.

The very birth of modern science from alchemy was series of mistakes... they were following some prescribed rituals, thought to be magical, but they messed up and invented stuff like eg, phosphorus. Also, mandragora was maybe ginseng and it really kind of prolongs life... but doesn't always grow on gallows hill..

So, if some next generation of science emerges, it may very well be results of mistake, done by current AI alchemy crowd. At least, the face similar problem: they spent whole lot of funding to deliver some promised miracle, sometimes even literally same, as alchemists did... and in the process, they invent and share various tricks, and even made the mistake of inventing chemistry....

So it seems to me to do something with a chance of new discovery by mistake, which can happen even by trying manned spaceflight. On the other hand, investing into basic research, which can be trusted to really not even predict anything, is kind of strange game...

Eg., from the point of view of military technology, it is absolutely safe to fund string theorists, because they are not likely to produce any terrible "string bomb" or something like that :-) You don't even risk creating another universe by mistake, or so: only lot of very nice papers and diagrams and equations are going to be published, with no dangerous real world consequences (which is not such a bad societal outcome... kind of art, maybe...)

So you can choose to do something, which is guaranteed to NOT give you any breakthrough, not even if you do it wrong (think about preserving some sacred texts in monastery) ... or you can do something, where the results can be random and poorly understood. (like eg. Podkletnov or so...)

Anyway: if something doesn't work, I don't think it is because "they are hiding it from us", but rather because not enough mistakes were made... yet :-)

@xChaos @coreyspowell Yes mistakes do lead to new things but they were doing what we call experiments. That is part of science. Yes doing anything may lead to a mistake which might benefit humanity. But if that is the approach then just do random stuff doesn't matter what. Which I guarantee will not really get places.

I don't know where you get your ideas that basic science can be trusted not to predict anything.... Everything, every technology is based on basic science.

Do you not think the first work on nuclear fusion was a load of equations.... Nobody knew it would lead to a bomb...

I have no idea where LLMs go, it's not AI of course. But they by their very nature do not seem to add knowledge but then again they are not my field.

I can't make any sense of your statement about choosing to do things.

Oh and it's not clear whether the Podkletnov effect is real or not as, at least from my cursory look, it's not been replicated. But again it's not my field.

Anyway thanks for the discussion. I think this has run it's course

@SamanthaJaneSmith @coreyspowell

This is complicated. I did not say "basic science can be trusted not to predict anything".

I just believe, that there are certain fields of research, which are generally not expected to turn into applied research and technology.

Fusion technology is special example, one of my favorites. I am 52 years old. But since my 12 years or so, fusion was available in 30 years. The basic principle works... somehow. For some time. There was tremendous amount of both theoretical and practical work done. Except... it does not seem to be scalable anytime soon. It is like trying to power steam locomotive with Heron steam engine: in theory, it should work. It is even kind of steam turbine! But in fact, the actual steam engine was built quite differently. So you can have knowledge, which is basically right, even known for centuries, but still get no practical results.

The popular summary, that inside fusion reaction, there would be "environment like inside Sun" is oversimplification: Sun is huge, but the average density of fusion reactions inside is just fraction of what would be required inside tokamaks. So the required environment would be actually much more extreme. It works in theory, but the engineering might never be sufficiently advanced - who knows. But the popular belief is, that it may be the only possible future.

So the society is just giving away certain constant, but probably not sufficient, amount of resources to fusion research, always not enough, so the they slowly crawl towards better and better results, which definitely prove, that it works... but at the same time, practical application is always 30 years in the future. You would also activate spent reactor vessels with neutrons, while turning them into heat... not really long life nuclear waste, but still...

So fusion is good question: if we put more money into fusion, than manned spaceflight or let's say, particle accelerators, would we finally get it working?

@SamanthaJaneSmith @coreyspowell also: can we except some breakthrough in nuclear physics, thanks to large colliders, which would help us to finally get fusion right? I seriously doubt so, but again, I am not expert... just maybe hard science fiction fan, or something like that. But there is still this "theory of mistakes", that when you are trying something, you can discover something completely different...

But the problem with fusion is mostly engineering... and perhaps few other problems, which are not just engineering, but rather extremely complex math, which you probably won't figure out without trying. So you iterate and try to make it slightly larger and different... so perhaps more teams in the world should be doing this, and not something else, but while it is applied research, you are still not guaranteed to achieve useful results.

So the activity kind of reminds me of ancient temple building. It does not automatically mean, that it is bad, because centuries ago, building temples was simply the way to organize society around some common activity, not directly practical (I am definitely not the first one, who has this feeling). Probably better, than fighting!

Do I want our everyday lives to rely on something as complex, as fusion energy? (or LLMs, by the way?). I am really not sure. I would rather trust something more simple, maybe. Solar panels and batteries are relatively straightforward and seem easy to understand. But they are not enough during the winter.... and of course, general computing seemed simple to me. But people wanted something more, than general computing could offer....

So perhaps: the basic research, which really does not threat to become the new key technology, on which everything relies, is not such a bad idea... I never said, that I am against basic research (even if myself I live and work outside of science and academia...)
