Normally, I’m all for language changing over time. If some word is used a certain way, so beit. But not here. Not in a case where people can end up saying dumb shit like “Evolution is just a theory.” I will physically fight people on that, If need be.
If you consider gross misuse (i.e. mixing up “theory” and “hypothesis”) to be a valid form of etymology (e.g. making new words), I have a question to axe.
(I apologize to linguists’ families who now have to clean up bodily fluids and/or arrange a funeral.)
To be perfectly fair, you can’t “prove” or “disprove” a theory. You can only discover new evidence that supports the theory or another competing theory. Multiple competing theories can be equally accepted as correct.
The issue is people using exactly that definition to reject science. We also have a theory of gravity, but gravity itself is an observation. Evolution should be too, regardless of our theories about it.
Also, String Theory isn’t doing anyone any favors.
I think anyone who uses the word “literally” to mean anything other than “in a literal sense” is a moron who never actually thinks about what the words coming out of their mouth mean, and I always will.
People who do not seem to understand that language is different than they wish it to be, are the actual morons. Not only morons, but pampas morons. Language is messy, imprecise, and always in flux. Language is a construct of the collective of its speakers, not you alone, nor anyone else. This is why we have specific lexicons for various industries, and academic fields. Even those are constantly being updated, and revised.
And, more importantly, I will use language as I please; I don’t have to justify my use of words to anyone. That is why I don’t see why people complain about using words “the wrong way”. Even if it is, I will still insist on my right to produce whatever gibberish my mouth is willing to put forward.
In fact, not even everybody has to understand it. If I say something that I think is true, but in a language that only I can speak, then it would be okay for me to say it anyways, even if nobody understands it. That is because while it’s important to always speak the truth, it’s not always important to be understood by others.
I remember seeing somewhere that the “colloquial” usage is actually the original and that the scientific community is the one that changed it. I do agree that the evolution argument is stupid but it’s hard to blame the non scientific populace for not knowing the distinction. The evolution denier just don’t have a lot else to stand on.
In physics we call some results “laws” and some “theories.” The difference has absolutely nothing to do with our certainty in the validity of the results.
Newton’s Laws of motion are called that because they can be written as concise mathematical equations, and allof the content is there. Einstein’s Theory of special relativity is just as valid, and even contains Newton’s Laws as a special case, but the content of the theory can’t be written in simple, concise equations. There are several equations included in special relativity, but they do not represent the entire content. For example, the most important statement of the theory cannot be written in equation form at all: “The measured speed of light in a vacuum will be the same for all observers in inertial reference frames, regardless of the relative speed of their reference frame.”
Darwin’s Theory of Evolution likewise cannot be written in concise statements (mathematical or otherwise), but our certainty in its validity is no less than in Newton’s Laws.
Another important subtlety: I was careful to say that we are certain of the validity. People who don’t know better are fond of saying that Newton’s Laws are wrong. This is a fallacy. Scientific laws and theories can only be valid or not, they can never be true.
A law describes what happens, a theory explains why. The law of gravity says that if you drop an item, it will fall to the ground. The theory of relativity explains that the “fall” occurs due to the curvature of space time.
In a scientific context, a hypothesis is a guess, based on current knowledge, including existing laws and theories. It explicitly leaves room to be wrong, and is intended to be tested to determine correctness (to be a valid hypothesis, it must be testable). The results of testing the hypothesis (i.e. running an experiment) may support or disprove existing laws/theories.
A theorem is something that is/can be proven from axioms (accepted/known truths). These are pretty well relegated to math and similar disciplines (e.g. computer science), that aren’t dealing with “reality,” so much as “ideas.” In the real world, a perfect right triangle can’t exist, so there’s no way to look at the representation of a triangle and prove anything about the lengths of its sides and their relations to each other, and certainly no way to extract truth that applies to all other right triangles. But in the conceptual world of math, it’s trivial to describe a perfect right triangle, and prove from simple axioms that the length of the hypotenuse is equal to the square root of the sum of the squares of the remaining two sides (the Pythagorean Theorem).
Note that while theorems are generally accepted as truth, they are still sometimes disproved - errors in proofs are possible, and even axioms can be found to be false, shaking up any theorems that were built from them.
Science can never answer “why.” In your example, the question why is just moved, from “why does it fall?” to “why does mass distort space-time?” In both cases physics just describes what happens.
Not every action needs a cause. Especially when entering the subatomic level, quantum effects appear to be fully probabilistic. Nothing causes the electron to emit a photon exactly then at exactly that energy, it’s just something that happens.
Even at the largest scales, quantum effects have shaped the structure of superclusters of galaxies and in many models underpin the beginning of the universe.
At these extreme ends, the concept of causality gets weaker, and asking “Why?” starts to lose meaning. You could say nothing caused many things, or equally say they happened because they could.
In all cases encountered so far however, learning more has enabled us to identify new limits on possibility, and usually to narrow down on the details. It’s a practically endless series of "why"s that grow ever more exact, until we find the limits of what can be known. Maybe this chain has an end, maybe not, but to claim that science cannot answer any “Why?” is just wrong.
Nothing causes the electron to emit a photon exactly then at exactly that energy, it’s just something that happens.
I have to say this doesn’t sound very scientific to me.
Science would settle at “it’s just something that happens”? Certainly not the scientist in me, lol. Everything that happens is driven by something, in my mind. Some process. Even if it “appears” probabilistic or whatever. Seems like a probabilistic model is applicable to the behavior, perhaps, but we can’t measure or see such small things so we can’t really make any more detailed models than that. Isn’t that right?
So just because we don’t yet have a model for it or understand it fully, but we can describe it with some model, doesn’t mean we are finished or should stop there, IMO.
It’s like saying the dinosaurs went extinct after the youngest bones we’ve found. Or that they are exactly as old as the oldest bones we’ve found. But, we haven’t found all the dinosaur bones, or at least we can’t know that we have or haven’t. And we definitely haven’t found the bones of those dinosaurs that didn’t leave behind bones.
Oh, lots of physicists think the same way! Even Einstein did, nearly a century ago he said “God does not play dice with the universe”, because the popular Copenhagen Interpretation posits that the stochastic quantum wavefunctions are reality, that there is nothing more. Both Pilot Wave Theory and the insane Many Worlds interpretation are attempts at describing quantum mechanics without the inherent randomness, and there are even more less mainstream theories.
Yet even today the Copenhagen Interpretation with it’s wavefunction collapse is still the most widely accepted interpretation among physicists. As of now, there isn’t any evidence for any interpretation, and just the barest logical evidence against some interpretations. We cannot tell even the general direction in which a better theory might be in. So far we can only describe the probability of things happening, and there’s nothing to say we need anything more than that.
Perhaps one day we’ll have discovered that the universe is deterministic and causality makes sense at every scale, but that’s definitely not our current understanding.
Sorry for taking so long to write a response. I had to think a bit about this.
So, I don’t think it feels very satisfying to the average physicist to just say “well, atoms sometimes just spontaneously emit photons”. It’s a model that correlates well with our measurements, but there’s no proof that it is true.
In some sense, the purpose of science is to make sense of the world, and it surely isn’t the most satisfying thing to be left without an ulterior explanation. That is why I think it is important to repeatedly ask why, until one finds the primordial source of causality.
Oh, absolutely! There are lots of physicists working right now to figure out the ins and outs of advanced quantum mechanics. There’s been a century long fight between the ones who think our current rules must be incomplete and the ones who don’t care why the rules are what they are so long as they work. There’s a surprising amount of dogma here too, with schools of thought being supported by proponents instead of science. I think that’s changing now, but I feel like that’s partly why physics hasn’t really expanded quantim physics at all.
So perhaps we will find a solid causal link between everything. Perhaps we’ll nail down entropy as a real property instead of just a statistical observation. Maybe we’ll truly understand the origins of not just this part of the universe, but the wider multiverses through time, space, and fields.
But maybe we’ll find that causality isn’t so solid, with time-like paths everywhere, and determinism only at medium scales. Perhaps the nature of existence is beyond gleaming for those held within.
Right now, we have no idea one way or the other. I definitely agree with continuing to ask why, but even the existence of the answers is up for debate, let alone the nature of those answers. I’m especially cautious of putting convenient explanations in the place of those unkowns.
So maybe saying so authoritatively that some causes don’t exists was an error on my part. Sorry about that. It would be more accurate to say that some causes might not exist, especially in some models, and that we can’t tell the difference yet.
where people can end up saying dumb shit like “Evolution is just a theory.” I will physically fight people on that, If need be.
Then again, why bother? If people want to say dumb shit, what concern is it of yours? It’s the same when people say “the earth is flat”. It’s not, but I would never fight someone over it. That’s just not worth my time in most cases.
I appreciate your passion for scientific literacy - it’s crucial for combating misinformation. However, I’d like to share some perspectives that might broaden our understanding of scientific knowledge and how it develops.
First, it’s worth noting that the distinction between “theory” and “hypothesis” isn’t as clear-cut as we might think. In “The Scientific Attitude,” Stephen McIntyre argues that what truly defines science isn’t a rigid set of rules, but rather an ethos of critical inquiry and evidence-based reasoning. This ties into the “demarcation problem” in philosophy of science - the challenge of clearly defining what is and isn’t science. Despite this ongoing debate, science continues to be a powerful tool for understanding our world.
Your stance seems to align with positivism, which views scientific knowledge as objective and verifiable. However, other epistemological approaches exist. Joseph A. Maxwell’s work on critical realism offers a nuanced view that acknowledges both the existence of an objective reality and the role of human interpretation in understanding it.
Maxwell defines validity in research not just as statistical significance, but as the absence of plausible alternative explanations. This approach encourages us to constantly question and refine our understanding, rather than treating any explanation as final.
Gerard Delanty’s “Philosophies of Social Science” provides a historical perspective on how our conception of science has evolved. Modern views often see science as a reflexive process, acknowledging the role of the researcher and societal context in shaping scientific knowledge.
Larry McEnery’s work further emphasizes this point, describing how knowledge emerges from ongoing conversations within communities of researchers. What we consider “knowledge” at any given time is the result of these dynamic processes, not a static, unchanging truth.
Understanding these perspectives doesn’t diminish the power or importance of science. Instead, it can make us more aware of the complexities involved in scientific inquiry and more resistant to overly simplistic arguments from science deniers.
By embracing some psychological flexibility around terms like “theory” and “hypothesis,” we’re not opening the door to pseudoscience. Rather, we’re acknowledging the nuanced nature of scientific knowledge and the ongoing process of inquiry that characterizes good science.
What do you think about these ideas? I’d be interested to hear your perspective and continue this conversation.
Normally, I’m all for language changing over time. If some word is used a certain way, so beit. But not here. Not in a case where people can end up saying dumb shit like “Evolution is just a theory.” I will physically fight people on that, If need be.
Theory meaning “unproven assumption” is one of the definitions in Merriam-Webster so it is not a new definition.
You’re just angry word means something you don’t want it to mean. Just like the literally-figuratively crowd.
If you consider gross misuse (i.e. mixing up “theory” and “hypothesis”) to be a valid form of etymology (e.g. making new words), I have a question to axe.
(I apologize to linguists’ families who now have to clean up bodily fluids and/or arrange a funeral.)
The aks variant pronunciation of ask is fine. It is part of a dialect.
It’s not gross misuse, it’s how the word work in common use.
To be perfectly fair, you can’t “prove” or “disprove” a theory. You can only discover new evidence that supports the theory or another competing theory. Multiple competing theories can be equally accepted as correct.
The issue is people using exactly that definition to reject science. We also have a theory of gravity, but gravity itself is an observation. Evolution should be too, regardless of our theories about it.

People who do not seem to understand that language is different than they wish it to be, are the actual morons. Not only morons, but pampas morons. Language is messy, imprecise, and always in flux. Language is a construct of the collective of its speakers, not you alone, nor anyone else. This is why we have specific lexicons for various industries, and academic fields. Even those are constantly being updated, and revised.
And, more importantly, I will use language as I please; I don’t have to justify my use of words to anyone. That is why I don’t see why people complain about using words “the wrong way”. Even if it is, I will still insist on my right to produce whatever gibberish my mouth is willing to put forward.
Edit: In other words, right to be wrong.
Yeah, as long as everyone involved understands what is being said I am fine with it.
In fact, not even everybody has to understand it. If I say something that I think is true, but in a language that only I can speak, then it would be okay for me to say it anyways, even if nobody understands it. That is because while it’s important to always speak the truth, it’s not always important to be understood by others.
The use of literal to mean figurative has been common for hundreds of years (literally). If it’s good enough for James Joyce, it’s good enough for you
And so is gravity, and the concept of colors.
I remember seeing somewhere that the “colloquial” usage is actually the original and that the scientific community is the one that changed it. I do agree that the evolution argument is stupid but it’s hard to blame the non scientific populace for not knowing the distinction. The evolution denier just don’t have a lot else to stand on.
Could you explain the difference to me? 🙏

Now do theorem
You mean, as opposed to lemma? I’ve never been confident that I understand the difference between those. :(
A law describes what happens, a theory explains why. The law of gravity says that if you drop an item, it will fall to the ground. The theory of relativity explains that the “fall” occurs due to the curvature of space time.
I was referring to the difference between a theory and a hypothesis.
Theorem would also be interesting to add to the mix.
In a scientific context, a hypothesis is a guess, based on current knowledge, including existing laws and theories. It explicitly leaves room to be wrong, and is intended to be tested to determine correctness (to be a valid hypothesis, it must be testable).

Science can never answer “why.” In your example, the question why is just moved, from “why does it fall?” to “why does mass distort space-time?” In both cases physics just describes what happens.
But that is why it happens. Causality in most certainly something that can be discerned scientifically.
But then, to follow up on your statement, what is the cause of all causes?
In other words, where does the chain of causes begin?
Not every action needs a cause. Especially when entering the subatomic level, quantum effects appear to be fully probabilistic. Nothing causes the electron to emit a photon exactly then at exactly that energy, it’s just something that happens.

/jk you’re entirely right
