The discussion centers on the potential for future scientific discoveries to challenge current understandings of physics, suggesting that established theories may be wrong from different perspectives. Participants emphasize that scientific progress often involves overturning previous beliefs, as seen with the advent of relativity and quantum mechanics. The importance of asking the right questions is highlighted, with concerns that complacency in inquiry could hinder future advancements. The conversation also touches on the compatibility of new theories with established measurements, asserting that any valid scientific theory must align with proven results. Ultimately, the dialogue reflects a deep engagement with the evolving nature of scientific knowledge and the philosophical implications of discovery.

The more we discuss this issue the more we agree. I never said that NP wasn't useful I just said it was wrong, its assumptions were wrong and its basic tenets were wrong and that Newton himself knew and admitted it. It worked and in most practical applications it still works within reason. That does not change the fact that it is wrong. I pointed this out as one example of it actually having happened in response to the original question of this thread.

You ask "what question?" My answer is any question.
You fear that one day the Omega will be upon us and we'll have nothing left to do. I'm more afraid that we'll give up trying to get there.
I don't fear it.
I'm not so sure about civilization.
I just think that one day, perhaps soon, that it will be here.
This thread is about how it would be observed.
Just posting some thoughts on that.
And wondering what we will then do?
It will not be a case of giving up. Giving up will not be an option.

Can we agree upon the following:
1)We must regard NP in its "ontological claims" dead wrong because it's predictions in several areas are way off from measurements we've made?
2)At these various areas, we cannot as easily dismiss the "ontological claims" of QM&GR for the reason that predictions we've made have a stunning match with the measurements?
3)That QM&GR can (and must) be regarded as more GENERAL theories than NP, because in the domain where NP works excellently, QM&GR in their respective limits reduce to the statement that "Newtonian effects" will be the most dominant effects of those we may measure?
(For example, in the limit \frac{u}{c}<<1, the Lorentz transformation will agree to a dominant degree with results stated by the Galilean transformation.)
4) If this hadn't been the case, (for example in that the Lorentz transformation did NOT reduce to the Galilean in the low-speed limit)
then physics would essentially have been sundered into 3 distinct regimes which had no way of talking to each other?
5)When dealing with complex phenomena in the region where the Newton approximation is excellent (let's say weather forecast, seismology, oil drilling, whatever), the reasonable scientific procedure is simply to disregard the "peculiarities" of GR&QM as simply unnecessary complications in our modelling practice.

If you agree to this, I retract all of my grumpier statements, and apologize..

I will go even further than that. In #1, NP is not dead wrong because of gross errors.
It is wrong because its assumptions are wrong (ontology). NP works as a very accurate model when applied to non-relativity velocities and situations. We still don't have a good handle on gravity or inertia other than characteristics of a theorietical Higgs Field.
#3, I would say that GR and QM are more general in that they are applicable under all or at least most circumstances.
Classical Physics is and remains a useful model for non-relative and non-microcosmic situations, that has never been in question. It is however limited to these situations and can not even be considered "special theories" as their basic assumptions have been proven by numerous observations in every case to be wrong.
If you want to call that ontological correct but applicably wrong then so be it. My point or opinion is that it is always wrong no matter how useful and accurate in normal circumstances it may be.
We also know that even as accurate and general as GR and QM are they are not complete nor completely absolutely accurate as we can't account for gravity nor merge the two together in one all inclusive theory of everything.
As all of you said it is more a difference of interpretation and/or view point than a difference of theory or opinion; i.e. we agree generally but not specifically.
Nor is it necessary to take back anything nor apologize as the rules here in the PF's in general and the Philosophy section specifically are:
1. No quarter asked and none given.
2. No holds barred.
3. All's fair in love and war.
4. This is all out war, and to mix my metaphors, if you can't stand the heat get out of
the kitchen, or if you prefer, the PF's.

NP is wrong (that is, the assumptions) are wrong because it necessarily predicts something which demonstrably, by evidence, is wrong.
It is falsified by evidence, and evidence remain (and I will continue to say so) the fundamental acid test by which any theory must pass.

Well, it is ALWAYS WRONG to call a first-order appproximation to a solution for an exact solution, isn't it?
(Such approximations are not, in general only to be found in NP).

To neglect terms in an assumedly correct diff.eq. in order to get a simpler problem is ALWAYS WRONG if that's what you want to say..

I don't see an omega.
I see an omega inside of an omega, and on until infinity.
I see us, our solar system, our galaxy, our universe,
And finally I see a blade of grass.
Where you see an end, I see only the beginning

And why are we making Haikus ?

Because you have read Stephen King?

I just use the imagery. The premise is still the same. use your own symbol. It could be a molecule, or any other form of existence. As long as the message gets across.

The haiku is actually pretty good :smile:

Personally, I am inclined to say that we are overdue for the next Omega point.
And I wonder why.

How silly are observers from the other side of the Omega going to think we are :rolleyes:
Right up there with the Flat Earth and Celestial Spheres. I'm sure.

Enjoy
