Wow, nothing stays the same except change. I just heard that Pluto will no longer be classified as a planet. We learned this stuff way back in grade school and now they are going to change this on us. It's impossible to keep up.

I get it but, this case if different.
In your example mankind expanded their knowledge and recieved some new information. In poor Puto's case we got no new information, we simply changed the DEFINITION of a planet.
Allow me to give you a perfect example of this:
Imagine the shape of our globe, if we chose the widely known shape of the earth before 1492. "For the sake of tradition, we'll pretend and teach our children that the world is flat, because we suddenly decide that flat means circular or gloval in shape. Of course the dictionary would now define round as something conpletely different. Changing things to conform to new data is OK but, to change the dictionary is ridiculous. You must have a constant on which you base all other knowledge." --Get it?
And don't shun poor Pluto now that she's no longer a planet. You can still send a christmas card, even if it's just to a large ROCK.
"obsolete" definition, new" definition - my head hurts.
Again, you must have a constant on which you base all other knowledge. Without a constant you have nothing. If an inch was not ALWAYS an inch how would you define a foot or a yard? Things can only change in relative to an absolute.
