We have only been doing science in anything near a methodological and serious way for maybe 200 years. It would be delusional to think we have a complete or accurate map of physics, cosmology, or metaphysics, especially since every culture before us had their certainties and most of those turned out to be wrong or very incomplete. We do have better cognitive and physical tools than the Egyptians or the Aztecs. I am reasonably confident in our “settled science.” There will probably never be a perpetual motion machine or an FTL drive unless it goes about it in some radical way that brings in some deeply weird implications, e.g. FTL where you can never be sure what slice of the multiverse you’re in at the other end of the flight. But there could be phenomena, forces, or aspects of physical reality that we simply haven’t been able to reliably detect or study. Or there could be insane weirdness hiding right in front of our faces because a fish might not notice water, and we are one cognitive leap away from a big reveal. My favorite personal wild speculation is that what we think might be psi, and sometimes shows up in experiments as such, is actually a side effect of something else like emergent patterns in complex systems or causality being weirder than we think. Nobody is doing ESP. Instead we are seeing something about information or causality as vexing as the double slit experiment, but we have not yet been able to wrap our heads around what is even happening. We can’t see it because we are in it, or because it’s just too weird. Maybe it’s witnessed in humans and other living things because life is tapping into quantum phenomena somehow where it becomes significant, such as by some kind of warm noisy quantum computation at the subcellular level. This is where whatever-it-is shows up, and also why attempts to detect it with electronics and machines fails. Just speculation of course.
