Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.
This is amazing news. It’s like being shown that Neutonian physics are wrong, so now we have the ability to come up with a better model, then massive advancements in technology can occur.
Bingo. All models are “wrong”, good models are useful despite being “wrong”. Relativity is wrong too since it can’t account for anything quantum… Relativity isn’t better, it’s just more accurate under certain conditions - but outside of those conditions it’s more complex than it needs to be, and Newton’s models are good enough.
So it works fine on human scales, but for most of the universe it is inadequate. That means it’s wrong. Quantum physics and relativity are also wrong since he are unable to reconcile the two, despite them both being the best models we have for their respective scales. We have known for the past century that we have only just begun to understand the universe, and that all our models are irreconcilable with each other, meaning that they are ultimately wrong.
Just because a model is useful doesn’t mean it is right.
I agree with the essence of your point but personally I’d never use the word “wrong”, only incomplete. Seems weird to call Newton’s laws “wrong” when the only reason that we are willing to accept GR is that it reduces to Newton.
It’s not so much that it reduces to Newtonian predictions but that at human scale and energy levels the difference between Newtonian and general relatively is so small it’s almost impossible to tell the difference.
What you’re describing is literally what it means for general relativity to reduce to Newtonian mechanics. You can literally derive Newton’s equations by applying calculus to general relativity. In fact, if you ever get a physics degree, you’ll have to learn how to do it.
Dangerous way of putting that since we have so many easily weaponized idiots who will carry that water, a better way to say it would be “our understanding of neutonian physics is incomplete at the moment”
I agree, it is more accurate that way. English is not my first language, so I missed that detail. In South Africa, we also don’t have a significant anti-science movement, so it does not always occur to me naturally. The scientific approach is generally well respected and understood here.

We did find out that Newtonian physics is wrong. Einstein got famous for it and we now use general/special relativity and quantum phsyics.
I think it’s better to say that Newtonian physics is incomplete rather than wrong.

Ah. So it’s relative.
No, Newtonian physics works just fine. Unless things are too big, too small, too fast, or too slow.
At least that’s what a meme I once saw said.

I prefer mine:
