I don't think so. Science in my mind is less about knowing and more about understanding/trying to understand things. If science was about knowing things, we'd have absolute truths. Thing is, we don't;everything we "know" has the potential to be "wrong" and affected by information gathered later. Actually scratch what I just said;if knowledge is the collection of things we perceive to understand then we absolutely have knowledge, but if knowledge is absolute facts of life/existence/whatever, we literally have none of it. We can't have absolute truth until every single data point that ever is, was, and could be is collected.
Science is like a big ball of wibbly wobbly, sciency wiency, schtuff. It IS magical fantasy lala land, thats what makes it cool. Thats how we managed to have this EM Drive do something it theoretically shouldn't have been able to do. It did something magical. And now using science we're gonna try to make sense out of it so we can understand it.

Words like 'know', 'knowledge', 'truth', 'understand', 'fact', are just fine, as long as one uses them in a context where they still have a meaning. A very common problem with young philosophers is that they, launching out into the extreme, move out of that semantic context and then pompously declare "there is no truth", "science doesn't know anything", bla bla etc. This is commonly exploited by murky powers, wanting to muddy the waters. Don't fall into that trap.
No, science is not a magical fantasy lala land. It's a rather strict discipline, the goal of which is to make, constantly enlarge and refine a sort of *map* of how things relate. Thanks to that map, we are then able to get from A to B in reality. Like when designing and building a working aircraft with performance according to design target. Or design and build a microprocessor. Or go to and land on the Moon.
The *map* is just a map. The symbols and concepts exists only in the map. But the map is often so extraordinarily reliable, that it's more than perfectly appropriate to talk about knowledge and facts. In any sense that those words can have any meaning, it is so.
The fact that the map is continuously updated and filled in with new details, old features modified, has no bearing on that. For the uses where the map, even the old map, is reliable, it is knowledge. It is what *knowledge* means.
There is no difference between how science and other "knowledge" -systems works psychologically or semantically. The difference is in the rather strict discipline that science adheres to, which produces and serves the reliability of the map. Religions, astrology, UFO-logy, New Age etc, are also just maps. They are human fantasies one can have knowledge about, but these systems themselves do not contain any knowledge. Those are fantasy lala-lands, because their systems lack the rules and discipline to discern knowledge from fantasies.
The map will always just be a map. It will never be reality. But this doesn't mean that we don't have or never will have "absolute truth", it only means that "absolute truth" is a poor, semantic concept, that has too powerful associations it doesn't deserve.
