No. You still have it wrong. I have never claimed that the number of planets in the solar system is subject to change, I have claimed that the number of known planets is subject to change. There is a big difference.
Further, also according to your stance, the only audience which received dogmatic instruction on the issue was the general populace... sun. It only reflects a change in classification and the language we use to communicate.
I have never claimed that the number of planets in the solar system is subject to change, I have claimed that the number of known planets is subject to change.
The amount of known planets has never been part of the conversation. The conversation has been specifically about what is known in the solar system, as it applies to the amount of planets thought to inhabit the same.
Actually I knew perfectly well as a child that the number of planets listed in preschool books was intended to be a list of known planets and not an exhaustive list of all planets.
Sure. And the "list of known planets" from when you were a child has just been changed. Except instead of being exhaustive, it appears that list was a tad too aggressive.
So no, I do not think the general populace received dogmatic instruction, I suspect you are in the minority.
We're not talking about my studies, we're talking about the general public. If the general public didn't think that there were nine planets in the solar system why do you think the folks at IAU even bothered making their announcement?
The very first website I found on the subject has this at the bottom...
That's hilarious. The very first website you found--- and inexplicably opted to cite anyway--- contains outdated information! And on top of it, in no way, shape or form does the citation you quote help your cause. There is no mention of anything that would lead the reader to believe that perhaps there are more planets, just that some of them haven't been photographed up close. Brilliant!
Now it is up to you to provide a quote of that 'rock solid' pronouncement.
That shouldn't be too hard. Check out iau.org for starters, or any other astrological websites.
From the Wikipedia page it appears that the matter was actually rather controversial and is still up for discussion in their 2009 conference.
Then I guess my primary point is underscored by you again: the scientists can't make up their mind. Go figure.
We could perfectly well decide that earth is the only body that we shall call a 'planet', but that would in no way reflect negatively on the scientific facts known about bodies orbiting the sun. It only reflects a change in classification and the language we use to communicate.
Let's see if I have this straight. You suggest that perhaps one day further definition of the term planet may come to exclude all celestial bodies but the earth, thereby rendering the solar system as made up of one planet and a bunch of, well, other bodies.
So, if I'm figuring this right (and I think I am), when or if that day comes, and we consider the solar system to contain one planet, will that be
more or
less planets than we have currently? Would that be a change, or would that be the same thing?
