Science!!

So we've gone from 12 planets (or more) to 8 in less than two weeks. It will now be officially a "dwarf planet". While I'm fine with this designation, the way this has been handled makes astronomers look pretty much like a bunch of jamooks.

The new clause that boots Pluto (and Ceres) out is that the "dwarf planet" meets all of the qualifications for regular planet but "has not cleared the neighbourhood about its orbit". As indefatigable42 has pointed out, a better way of saying this is that the object isn't unique in the neighbourhood. Ceres isn't, because there are several more  quite large asteroids around, and umpteen smaller ones. And Pluto isn't because we know know of several more large objects in the outer solar system, one which is larger than it is. All the eight "classical" planets clearly are.

Also, as has been noted elsewhere Gustav Holst's The Planets has the correct number of movements again!

At the monthly Canadian Space Society meeting Tuesday, we had filmmaker Michael Lennick as our speaker, probably best known for his wonderful Discovery Channel series Rocket Science.  His talk morphed away from the stated topic (how acceptance of risk has changed at NASA from the early days of spaceflight)  and became more about the forgotten pioneers of the Space Age, like  Joe Kittinger, who bailed out from a balloon at 100,000 feet, and how their efforts helped shaped  NASA programmes.  He has a new show coming up on PBS in the fall on Edward Teller, one of the father's of the H-Bomb (Dr. Teller's Very Large Bomb).

The post-talk talk went all over the place, but he said two things I found particularly interesting. The first was about how he had once considered doing a show about the idiots who don't think we went to the Moon (to be called The Moon Hoax Hoax) and in talking to college students who should have known better, he came away with three reasons they had doubts.

  1. It was technically possible to have faked it.
  2. It was "done" by the government, and the government lies to us.
  3. If we could go to Moon, why can't we now? How could we have forgotten how to do it?
The other item of real interest was regarding another show he's working on, When Good Robots go Bad, about creating a real artificial intelligence. He thinks that the first AIs will be sociopaths (much like HAL). They can think, but they won't think like us, and they won't "get" humans. He also says that the US government has been pouring money into AI research at NASA/JPL and other government labs, and that researchers have told him that they were about 18 months away from a real breakthrough. In that event it would probably be a good idea to not hook them up to anything more than a chessboard until we're sure they do like us.

You know, Capricorn One wasn't even that good of a film. To be the start a huge conspiracy is just sad. We don't currently know how to build pyramids anymore, but there they are.

Most conspiracy theories I've encountered seem to be due to Occam's razor having got lost at the back of the medicine cabinet - people get so caught up in working out elaborate ways that something *could* have been faked, that they don't notice that the theoretical fake method is usually at least as complicated/expensive as doing it for real, and riskier because of all the people who'd have to be in on it. I'm willing to believe at least a few people in the upper echelons of power got there by being amoral sociopaths, but they must be amoral sociopaths with realistic cost/benefit and risk assessment skills; the other kind wind up in jail pretty early in their careers.

Every now and again I dip a toe into the wonderful world of 9/11 conspiracy theory. Currently, the big thing is that cruise missiles were used in the attacks, not airplanes, and either 1) holograms were used to make the cruise missiles look like airplanes, or 2) every video feed in Manhatten was hacked in real time to replace the images of missiles with airplanes.

Because hijacking four airplanes on the same day is just impossible you know. Despite that fact that in 1970 a Palestinian terror group succeeded in hijacking three airliners simultaneously (they tried for four). The hostages were eventually all released in exchange for a few prisoners (the planes were burnt).

Well, we CAN build pyramids, just not the way they were done back...well..whenever they were actually done (Even discounting all the silly stuff, there's some questions that just don't fit observed facts). Someday there'll be a breakthru, some painting or something that will have some long missing clue. Or we'll find the anti-grav sleds and beam cutters under some statue :)

Like going to the moon. It's not really technology we lack, it's will, but that's an old, sad song. Man, if Bill Gates decided to fund a private SSTO manufacturing company and building REAL wealth for the world instead of throwing billions down the bottomless well of problems that won't be addressed by REAL solutions, think of what could be done.

I'm not at all happy with this re-classifying the planets thing. I know, means nothing in the bigger issues of today, but dammit, Pluto should be a planet. It just should. I know that when we finally get out there they're going to end up changing their minds again.

And Donald, props for the X-20 icon. That still bugs me, how FAR the project got and then *pfft* stopped. I mean, IIRC, they were at the 'bending tin' stage, everything was ready to go, and "oh, sorry, it's NASA and capsules now, thanks for everything but...no"

I'm surprised Boeing didn't just say "screw you' and went ahead, knowing full well that with a proven ship, the Air Force just might come back, and if not them, NASA would surely find a use for it. I mean, good lord, look at how much money was spent on aircraft built 'on spec' all thruout the '50s and early '60s...proof of concept, testbeds...

Of course, there's the fringe that says it WASN'T cancelled, that the USAF has been flying the Dyna-Soar for decades now, but you know all that has to be banana juice...

DAMMIT! I want my 'Wheel' in space! I want SSTO! I want my moon bases! *pant pant pant*

sorry.

Nah, they're flying X-302's out of Groom Lake. The Stargate program has gotten so big that NORAD had to move out of Cheyenne, y'know...

Hiho,

And I'm going to use this post as a forum for my latest gripe about this definition: Is there a defintion of what a planet's "neighbourhood" is? Or are we going to get into situations like:

Scientist #1: Chavroom is a planet.
Scientist #2: No, it isn't, because Chavram is in its neighbourhood.
S1: What? Chavram is clearly outside of Chavroom's neighbourhood.
S2: No it isn't.
S1: Yes it is.
S2: No it isn't.
S1: Yes it is.
S2: Oh, look, this isn't even an arguement.
S1: Uh... yes it is...
S2: Oh, shut up.

And so on? :)

Cu,
Andrew

Not to mention, there are plenty of asteroids that cross the Earth's orbit (the Apollo asteroids, I think they're called). Does this mean that the Earth hasn't cleared its orbit and shouldn't be called a planet?
