Yes, but you miss the point.
Science evolves and what was once a cast-iron certainty is now discarded. People used to believe that they would die (as passengers) if trains went at more than 30 mph. Serious people believed this! There is no telling what science will discover in time. BTW if they 'very rarely change' - they change!
If you went back in time (which probably defies the laws of physics, but never mind) and met the founder members of the Royal Society, you would find a group of very serious, very learned men. You would also be astonished by their ignorance of things we have long since accepted as being factual. I do not predict what the future holds, but I do believe that in 500 years or so they will hardly be able to credit our ignorance or the inadequacy of our understanding.
