Falsifiability is critical for engineering, but not all science is for engineering. The further you get from engineering, the fuzzier the line between science and non science.
We try to apply the tools of science to things like astrophysics and paleontology, but they're practically never going to have engineering consequences. That's fine. It's great that we want to know stuff just because we like knowing -- even if "knowing" sometimes gets hard to define.
Falsifiability is a great tool for being able to say some things don't work. But it's important not to let it limit curiosity.
