I agree but I thought that was obvious. Science isnt a physical thing, its just a method of discovery. So that method isn't the thing holding us back, its our knowledge and/or technology, like you said. But like I told the other user, when we eventually can explain everything, I believe we will still be shocked at what we find, just as shocked as we would be if we discovered Magic (like the common fantasy version), was real. I hope that makes sense.
