In any case, after the next science paradigm shift, what we now know may be seen as incomplete and ridiculous.
What we now know is already seen as incomplete, because we see it is, but it will hardly ever be fair to call it ridiculous.
For example, Newtonian physics is two paradigm shifts behind and the only thing that's ridiculous about it is how incredibly strong it's predictive power is.
No mathematical construction we may use to explain and predict the behaviour of the universe can justify itself, so, there must be some kind of meta-physic behind it.
But that's unsurprising. After all, mathematics can hardly justify itself either - it's unclear what that may even mean, but it is a theorem of mathematics that for interpretations which would now be considered reasonable it isn't true.
If you want to take things to the extreme, in the end no form of human inquiry is impervious to a sufficiently obtuse form of epistemological skepticism. And you always need a meta-theory: in case of science that's at least the philosophy of science.
So imagine that a guy from the future gets here and says the equivalent of Battuta or any other folk going to Newton and just say "Hey look pal, particles are also waves, and we can't ever determine both their speed and position accurately, and spooky entanglement exists, and objective histories are a sham, and and and". You'd immediately laugh at the guy.
Ok, but why wouldn't I? I mean, people tell me all kinds of **** on a daily basis.
If that hypothetical person can explain to me the mathematical model behind his new theory and convince me its consistent and has general relativity and quantum mechanics as limiting cases, I'd have hopefully stopped laughing. But even if that's possible, it would take years.
