I think this is a misunderstanding people come to when we say 95% of the energy in the universe is invisible to us, they assume that means we only understand 5% of everything. While it in fact takes a great deal of knowledge to understand that there is a portion of the universe invisible to us. In the most broad strokes our understanding of the universe is pretty much correct in the way Newtonian Mechanics are pretty much correct. Newtons gravity did a very good job of explaining the way objects would interact together, and those explanations still hold even as relativity and quantum mechanics have turned those laws on their heads and given us a better more detailed way of explaining many of the same interactions. I think we can confidently says the Universe will end up being in the range of 13.5B years old, the year 4.2B, FTL travel is not going to work within the confines of normal space, evolution is how living populations come to be... We may gain deeper and more nuanced explanations of these things, but we aren't about to learn everything we know is wrong.
