Splain?

I hear we keep bouncing shit off of it, so we conclude something is there.

That you see everything that that isn't emitting light, by light bouncing off it. :p
It does however have to be something that is larger then the wavelength( or something like that) . Which is why we use various types electron microscopes to view atoms.

The problem with keeping Pluto in is that if you do you would need to allow in all the other trans-neptunium objects of Pluto's size. That means we would likely be looking at not nine but 12,13 or perhaps 20+ planets which even the most conservative of scientists have trouble accepting. Sad to see Pluto go but it fits well with our growing understanding of solar system dynamics and evolution.
And once New Horizons arrives in that neighborhood, you'll probably have all kinds of Kuiper Belt Objects knocking on the door. If there's anything out there as dark as the darkest part of Iapetus, there's no way we'd ever see them from here. (And NH would probably have a tough time too.)



Sorry, Tsavo's still got you beat.


12/12

I'm going to go get me a job now with this quiz score on my resume. recruiters will be impressed by my 90 percentile placing.
Yes, I believe I would like to Supersize my fries today, thank you.

But there really isn't any science behind the designations, it's simple classification for classification's sake. It's like arguing about whether a particular mountain is really just a hill.

Hmm....

Here's a planet
There's a planet
And another little planet
Fuzzy planet
Funny planet
Planet
Planet
Truck

Don't ask.


Anyway, the whole thing with Pluto is a bit unfortunate; no planet had been discovered since Neptune, which was in...(checking; I used to know this, but sadly have forgotten:()...1846.
So hey, we see something way the heck out there, moving! PLANET PLANET PLANET!!!!!!
Then later on we find out that it's a little rocky iceball with a few more tiny iceballs orbiting it. And it's in some 3:2 orbital resonance dealy with Neptune. And that particular orbit is likely occupied by lots of other similar objects.

Demotion! Sorry! Please accept our apologies and this complimentary gift basket, which should be flying by in about 5 years.


(And yes, one of those things isn't a planet; we just don't have many planets to choose from which I'd call "fuzzy.")

That reminds me of driving through the coalfields of eastern Kentucky. I'd be driving down some narrow little mountain road with a mountain on one side and pampers trees on the other. Then I'd look in the rear view mirror and see nothing but one big "A".

I like that moon, Hyperion. Very cool.

12/12 what's funny is a large portion of those facts I've learned from TV and at least half of them from commercials.

That was really easy, and I'm essentially a layperson. Do people really get less than 12/12 on this?

I got 11. Got the aspirin question wrong. I don't take medication, I don't go to the doctor, and I don't watch or read the news. Haven't taken any kind of pill in about 8 years.

I got 11. I thought antibiotics kill bacteria, based on the fact that I vaguely remember there are some creams you put on your cuts to kill bacteria. In retrospect I realize those weren't antibiotic creams...

Antibiotics are suppose to kill bacteria... they don't kill viruses...

Antibiotics do kill bacteria.

Truthfully I didn't know that one immediately, had to break down the word into anti-bio = anti-life, virus is not life, therefore antibiotics don't kill viruses.

Aah, interesting. I guess that makes sense - antibiotics don't help against flu, etc.

The way the question was worded should have been a giveaway. It's common knowledge(I thought anyway) that antibiotics didn't work for everything. They worded it as viruses AND bacteria. That was the giveaway. It doesn't matter which they don't work against as long as you know it can't be both.

Well yes and no. Let's face it scientists want precise definitions and you can't really blame them for that. Even with mountains we all tend to draw the line somewhere, I think most people would look at you funny if you called a 20ft high hill a mountain. With planets the need arose when it started to become obvious that we were going to discover a LOT more Pluto sized objects out there with strange Pluto like orbits. Most people including the average person would have difficulty with the idea of 100 planets or more. When you look at it this way Pluto and its family really do stand out. Its orbit is inclined sharply with the plane of the solar system and it's part of a family of small rocky bodies out beyond the orbit of Neptune. In this light it seems more like a large asteroid. In fact the IAUs definition is fairly clear cut, it's not just a body of a given size.

"
The defining dynamic characteristic of a planet is that it has cleared its neighborhood. A planet that has cleared its neighborhood has accumulated enough mass to gather up or sweep away all the planetesimals in its orbit. In effect, it orbits its star in isolation, as opposed to sharing its orbit with a multitude of similar-sized objects. This characteristic was mandated as part of the IAU's official definition of a planet in August, 2006. This criterion excludes such planetary bodies as Pluto, Eris and Ceres from full-fledged planethood, making them instead dwarf planets.
