Everything changes, at one time the earth was flat and the universe revolved around it. Science at any given time is our best guess, with all the currently available evidence. There will always be differing opinions and only time can tell, the differing opinions allow us to think more freely about the possibilities, which may not yet have been thought of. If you are told there is only one solution you won't try and find the ten or more other possibilities.
Sometimes the incorrect conclusions from the past did help, such as disease was spread by smell, the 'smell' doesn't spread disease but their assumption led them to move waste and smelly things away from clean things such as water sources etc which was good for them, but may have limited any further thinking.
Surely as we increase the scale and granularity at which we can observe we will never stop learning, and changing our constants. I've heard that even Pi gets larger as we get more computing power to be able to define it to a higher number of decimal places.
I look forward to seeing the book.
