That's the best part about science.

I am a bit sick of this narrative. That science can make mistakes is in no shape or form, one of its strengths. It is a weakness of the process. The lipstick putting can be exposed by simply asking if you would not prefer a version of the scientific method that is never wrong.

No human process is perfect. Every human makes mistakes. If more people were able to admit being wrong the whole world would be a better place.

It isn't making mistakes that's a strength, it's the commitment to acknowledging and addressing mistakes.

The thing is we have a lot of models which make very accurate predictions most of the time, which are useful for doing some impressive science. But we have no accepted theory of what is actually happening behind the math. What we have is that in 1925 most theoretical physicists decided that we have already uncovered the most fundamental structures of the universe and further investigation into how or why things are t…

> in 1925 most theoretical physicists decided that we [are done] No. Just... no. Even advancing that fifty years to 1975, the Standard Model reigns not because people want it to reign, but because no one can knock it off its throne. There is no better idea that can explain more than the Standard Model can. It's not a conspiracy. (I did used to joke with my students that progress in physics stopped around 1975, which…

From my understanding of the parent I think he's not saying that nothing is trying to replace the standard model etc. But instead nobody is trying to explain the standard model (or whatever).

For example, wavefunction collapse. You can see the wikipedia page for all its interpretations. There's no such page for Newtonian dynamics (even though gravity is also spooky action at a distance) and classical EM (you're telling me there's more of these fields everywhere I can't see).

I think it's simply because classical experiments are a primary source and quantum experiments are a secondary source of information. The classical case you just see and know the result. Quantum experiments you're always looking at some medium that detects or measures or whatever the original interaction. So you're only interrogating the detector, not the original particles or interaction. So of course we're stuck with an interpretation problem. It's the same problem with news. The primary sources are always 100% certain what happened because they saw it. The secondary source will allow for more interpretation because they have heard from multiple primary sources, etc.

9 years of philosophy and I'm over platonic realism and reading contemporary philosophy of science. The thing is, we are wrong, but this stuff is useful to make predictions. Everyone knows about the copernican revolution. But when it first happened, the old models(earth at the center of the solar system) were more accurate at predicting where the plenets would be.

The difference with the Copernican stuff is that you can fly a satellite (e.g. Voyager) to the edge of the solar system, look back, and see the planets orbiting the sun. There is no sane way to put the earth in the center once you do that. If I do a push up the Earth moves beneath me but no reasonable person says I'm pushing the Earth away. Hence I feel heliocentrism is simply an observable fact. It's not a mathemati…

Aye, but we only sorta kinda "know" what things like black holes might be. We have models that make sense to us based on our understanding of science, and we think our instruments can faithfully report on what they can be with measurements we believe we are making correctly, but we have no clue what we don't know, and no real way to prove it, just theorize, and sort of bundle up what we believe is data supporting it.

There are so many observations that fit the theory at this point, that we know there is a supermassive black hole in the center of our galaxy just as well as we knew the earth orbited the sun before the voyager flight.

Academic here. It's actually great for us. You're usually the first to see the implications for your niche area and have a chance to get a hot paper out rather than a moderately impactful one.

I think it depends on who has the hot paper and who has the outdated results. I was in academia for quite some time and when sometime cool comes out that renders other results less important, there are always winners and losers beccause the only thing that matters in academia is impact and the latest and greatest - not the blind alleys along the way. There isn't really an "us" in academia like there is in a private c…

im pretty sure in private companies people are vying for promotions and trying to out maneuver their colleagues in the eyes of management. just look at ai use, johnny knows how to prompt better than sammy, so johnny looks like a 2x more productive programmer. its every man, woman and child for themselves.

We have very good ideas about it, including the issue described in the OP. We also don't know how gravity and the other forces work together. We don't know where other life is in the universe. We don't know how to travel to other stars. We don't know what is under the surface of Europa (but we'll soon find out).

And we have a very good idea of what we know because our theories, based on our observations, predict things accurately.

The original upthread comment and followup seem like taking some philosophical questions to logical extremes.

The Higgs and black holes are quite different. We've basically observed Higgs according to how we've defined them, while we've only observed phenomena consistent with black holes as we hypothesize them. Singularities are the result of theories based on (ironically named) real numbers, it's entirely possible that what we call black holes are really dark stars formed from exotic matter that can only exist in hyper-extreme conditions, like a leveled up neutron star.

Hmm, fair enough - I checked Wikipedia. My mind completely erased the "sophon" bit or whatever it was called, it just got erased again. Not a fan of that particular fairy dust. I thought they were referring to the inability of the aliens to make an accurate calendar.

No, I was referring to the human scientists' reaction to the sophons' interference. But I thought that the Trisolarians' inability to predict their planets' path also seemed weird. Yes, the three-body problem isn't analytically solvable, but you can brute force it, and I would imagine that a species that is capable of creating sophons and starships with hulls made out of the Strong-force could calculate their planet'…

I believe at some point they disclose the Trisolaians aren’t actually interested in “solving” the problem. They do have analytical methods, but the problem isn’t prediction but rather the fact that everything they have will routinely burn to the ground and they’ll need to restart from 0. Also they will at some point get flung into a sun.

The “we need to solve this problem!” thread was a ploy to get earthly scientists invested in their plight such that they could convince them to support their cause from the inside.

I think it is similar to the 'All models are wrong but some are useful' adage.

There is reality and there is the math at which we point at it with. The pointing will never be reality but that doesn't mean it is useless.

In the same way you cannot blow the wind with the word 'Fan'. But the concept of a fan is very useful.
