welcome to the fray kbertsche.
If it's not falsifiable, it's not science!
It is amazing how often this needs to be repeated eh?
I am really surprised at how many folks here misunderstand or disagree with the scientific method! I am new to posting here; my initial impression is that this crowd is either not very scientifically literate or is intentionally being disingenuous to promote some agenda other than science.
Stick around. I think you'll find there are three kinds of posters here: your typical creationist (who can't be swayed by any amount of evidence that contradict what they believe they know), people of varying education levels with a keen desire to learn more (and some may think they know more than they do), and bonafide science types (with the education and resources to document and substantiate what they say).
I put myself in group two.
Enjoy.

The experiment took many years, but in the end the results were clearly in conflict with the predictions. The result? The theory survived unscathed, even though the data were (and are) perfectly valid. What had to be changed was not the theory, but an auxiliary hypothesis about the behavior of neutrinos.
So there was a theory that was falsified and that was changed: the one about neutrino behavior.
The hypothesis that was based on the theory is still a hypothesis that is allowed with the change to the the theory of neutrino behavior, but it has not been tested yet.
This gets more into theory based on theory based on theory than it does on theory falsification.

That's why you can't know for certain that you have disproved a theory any more than you can know for certain that you've proved one. Both falsification and verification are problematic.
So you think it is actually possible that the earth is flat?
(Or rather, a better theory for neutrinos was found to match neutrino behavior better than the existing theory, which is not exactly the same thing.)
The original theory did not match the data so it was falsified, the result was to modify the theory to match the data. What part of this is not the scientific process? Knowledge was still increased by the process yes?
The point is, however, that they thought they were testing a theory about the sun, but weren't. This is always a possibility when you have evidence that you think falsifies a theory -- maybe it's actually some other assumption that you've made that's wrong.
Which is why it is unreasonable to build too many theories on top of theory on top of theory with some steps involving unvalidated theories (hypothesis really) ... however this too is part of the review process on any theory in conflict with the evidence: the question is where the error comes from, not a discarding of the evidence to maintain the theory. Any part of the logical foundation can be the source of the error.
Both falsification and verification are problematic.
Validation is always problematic, but some things are definitely falsified with no equivocation: that the earth is young is one. We may not know exactly how old the earth is, but the certainty is that it is not less than 4.5 billions of years old.
Enjoy.

Do you really think we can say for certain that the Earth is not flat, but that we can't say for certain that the Earth is roughly spherical? Because that is what is being argued.
We can refine that to being roughly an oblate spheroid ... in the end we'd end up with a variable shape depending on the position of the moon and sun ... and hot spots and ... (I don't think there is a single shape involved eh?).
Each step of the way we move closer to what in reality exists. Yes we can definitely rule out flat, it has been invalidated.
Invalidation means that we no longer need to consider a flat earth within the realm of possible reality, as we hone in on what that reality is.
That would be the scientific process if it had happened that way, but it didn't. Scientists did not look at the data and say, "Aha, it disagrees with our theory about neutrinos, and therefore the theory is wrong."
It seems to me that you are arguing that they didn't make any changes at all to accommodate the data while pointing out that they made changes to accommodate the data. What part of evaluating all the elements that go into the prediction that did not come to pass to see where the error in making the prediction came from is NOT covered by what happened? This includes all theories involved.
Of course the more theories that are involved in a prediction can muddy the picture of which theory is falsified by a failed prediction -- this is the fault of using multiple theories before they have been validated than the fault of the theory.
The problem with your comment is that essentially all of modern science is built of theories on top of theories on top of theories.
My quibble is that some being used (especially in physics it seems to me) are without sufficient validation to qualify as more than a hypothesis and this leaves the structure more like a house of cards so you don't really know which card caused the house to fall. There is a difference in degree when using theories that have passed many prediction invalidation tests to build new theories and in using new ones that are barely out of the box.
What I am arguing is that falsification is not the essence of science, and that disproof is just as problematic as proof.
And you have failed to make your point. Repeating your assertion does not make it any more valid. The example you provided showed that invalidation occurred when the data did not match the prediction, that a change in a theory was made as a result. It was not the one that was used to make the prediction but it still occurred. Bad information was still ruled out and we are more honed in to what the possibility of reality is than before.
We also still end up with the point that IF they had not found any error in the foundation and structure of the house of cards that the top theory that was the source of the prediction would have been falsified by the data. Now they need to make new predictions to test the validity of the theories and see where that leads us in the quest for knowledge of reality.
Enjoy.

So are you saying we can validate things in science, or not? Previously you claimed that validation was problematic in ways that invalidation was not. Is that true or not?
I use validated for theories that have been tested by predictions that they have passed:
val·i·date -verb 1. to make valid; substantiate; confirm: Time validated our suspicions.
2. to give legal force to; legalize.
3. to give official sanction, confirmation, or approval to, as elected officials, election procedures, documents, etc.: to validate a passport.
This is distinct from proof. You can falsify - disprove - theories you cannot prove them.
The theory that the world is less than 10,000 years old is proven false by the evidence of tree rings alone.
The original claim was about testing a theory against data. In this case, a test of a particular theory was made and the theory failed, in exactly the way that is supposed to falsify a theory, and that theory was not falsified. Data that contradicts a theory may not falsify it. In this case it was another theory that was falsified;
You have repeated this several times yet fail to see that results contradicting a prediction falsified A theory and that theory was changed. IF that had not occurred then the theory in question would be falsified. Failure to see that this is in fact the scientific process is just denial of the facts.
Perhaps you have another example eh? Otherwise you are flogging a dead horse. The fact that you personally don't like the result has no bearing on the validity of the process.
Enjoy.

The evidence that the earth is older than 10,000 years is what disproves the theory that the world is 10,000 years old.
and simultaneously maintain that the theory that the world is more than 10,000 years old has not been proven true.
That is not a theory, that is the evidence that disproves\invalidates the above theory. Evidence is not theory, it is fact. Facts disprove theory.
Because of the evidence available, the theory on the age of the earth has been revised and currently is that it is 4.55 billion years old. This theory on the age of the earth is still not proven.
I'll ask you again, since you ignored my question the first time.
I thought you'd figure it out. Apparently you have been confused between evidence and theory.
Enjoy.

equivocation
This was your original claim:
Message 50
Sometimes the theory is changed, and sometimes it's scrapped, and sometimes neither happens. Take an example: Ray Davis's solar neutrino experiment was devised to test solar models, which made specific predictions about neutrino production by solar fusion. The experiment took many years, but in the end the results were clearly in conflict with the predictions. The result? The theory survived unscathed, even though the data were (and are) perfectly valid.
Now you state:
How can have I failed to see that the results falsified a theory when I stated exactly that?
We are still talking about the same issue, no other one has been introduced. This is called equivocation.
My job is done, thank you for playing.
Enjoy.

According to you, "The Earth is less than 10,000 years old" is a theory, while "The Earth is more than 10,000 years old" is not a theory. Uh huh.
Correct. The theory "The Earth is less than 10,000 years old" is falsifiable (and falsified) while the statement "The Earth is more than 10,000 years old" is not falsifiable as it is a fact.
You're right, your work here is done.
I'm glad you concede that.
Enjoy.
