		<description>I think some of you are way too testy about a simple toy. There are toys that &quot;aliens&quot; &quot;ghosts&quot; super heroes that fly, etc.. All sorts of toys that don&#039;t exactly exude accuracy in real life! At least Fisher- Price has found a toy that has my son excited about the planets. He could name them all in order at age 3. The dvd&#039;s are cute little cartoons intended, I&#039;m sure, to ENTERTAIN children. By the way, in the third dvd, there is a flying moon cow that saves the day. We live on a farm and my son isn&#039;t trying to help our cows jump over the moon or fly or save the solar system! So -- maybe (just maybe) children can understand that EVERYTHING they see on TV isn&#039;t real. Please find another way to sell your book other than petty attacks against a preschooler&#039;s fun little toy.</description>

		<description>Thought Matteo, my 4 year old son, as of 8/17/08, was only Planet Hero lover.
Thanks for your support,my wife and I have taken Matteo to planetarium,
but he was too young at 2 and 3.</description>

		<description>Hmmm, Firefly wasn&#039;t all bad. As far as I recall, it is 1 star, multiple planets, and the worlds are all actually moons. Hence why some can be travelled between quickly, and some take weeks. It was supposed to be that way. The old west had to move slowly from place to place, so autonomy from a centralised/federal government was easier. Firefly is suggesting that we can return to that pattern once distance becomes so great again that we can&#039;t just cross the entire empire in a day.

Of course the bits involving reaver chases, proximity, and communication (the &#039;cortex&#039;) are obviously wrong.

As for terraforming, I think we are meant to use our imaginations. There was enough population or not enough equipment, so the centre worlds were colonised/terraformed first. Then they did the outer moons. There may be social reasons why the worlds couldn&#039;t be properly developed.
Hell, Australia wasn&#039;t exactly exploited for its resources. Why move to a hellhole when you can just deport undesirables there?</description>

		<description>&quot;And that’s only diameter. The galaxy has depth, too. Its volumes is approximately… let’s see… carry the three… a bajillion times that of the solar system. It’s no contest.&quot;

That gave me a chuckle. Cheers.</description>

		<description>Dunc:

&gt;There are several instances in Firefly when the word “galaxy” is used instead of “system”. As in: “The Earth got used up, so we moved out and terraformed a whole new galaxy of Earths.”

I always assumed that they didn&#039;t mean galaxy as &quot;a lot&quot;, not the literal meaning of the word. Guess that is why they didn&#039;t pick up on it.

As for the rest of the physics in Firefly(going places too fast), i really do not know how long it would take to fly from earth to Jupiter with a relativistic drive. And they never did explain how they were propelled(ie, in the series, i don&#039;t think i ever heard them say that they were going X% of lightspeed or anything like that).

BUUT, i don&#039;t want to start a whole physics in the firefly conversation, i fully agree with you, it was just the galaxy thing.

And what they did in Farscape was brilliant.. &quot;Einstein was wrong&quot;.. nothing more.. nothing less.. me like :)</description>

		<description>Well, if nobody else will - no fear of LHC black holes, seriously.  If Hawking is right, these will &quot;evaporate&quot; rather quickly in a burst of radiation and particles, which will probably be their signature while still in the collider.

Of far more concern are negative strangelets, as outlined in this paper:

http://arxiv.org/PS_cache/hep-ph/pdf/9910/9910333v3.pdf

;)  - oh, just somebody TELL the folks at TU24 that the asteroid is made of negative strangelets...</description>

		<description>Black hole in the solar system? I&#039;m surprised that no one has mentioned Riofrio; slowing light and GM=tc^3 and all, implying that tiny primordial black holes haven&#039;t evaporated by Hawking radiation, etc.</description>

		<description>I try to get the science right in my SF.  I include some old unscientific SF tropes necessary for the story, like faster-than-light drives, but even there I use a jump or space-straining of some kind (a la Alcubierre) rather than just having the thing zoom past c on some kind of thruster.  Maybe only the Niven-boy science geeks will get it, but I just feel better writing the stuff as accurately as I can.

Of course, getting the tech stuff right doesn&#039;t mean it&#039;s good writing...</description>

Phil didn&#039;t scrounge kids toys looking for the blurb -- I sent the pic to him after I noticed this watching my kids pore over gaudy plastic toys.  Yes, I was bored.  And yes I need a new day job but for different reasons.</description>

		<description>&lt;i&gt;Agreed, but that isn’t exactly what TBA said above.. He said Joss confused the solar system with the galaxy.&lt;/i&gt;

There are several instances in Firefly when the word &quot;galaxy&quot; is used instead of &quot;system&quot;. As in: &quot;The Earth got used up, so we moved out and terraformed a whole new galaxy of Earths.&quot;

And seriously guys, I dug it as much as the next rabid Sci-Fi fan, but there&#039;s lots of bits of the physics (and economics) that don&#039;t actually make any sense. Sorry. Joss just chose not to draw attention to those shortcomings with reams of treknobabble.

(Since I know someone&#039;s going to ask... For example: in the first episode they can communicate with no discernible time-lag over a distance that will take some time to cover [I forget exactly how long]. So they must be travelling at pretty low speeds relative to &lt;i&gt;c&lt;/i&gt;. But they can travel between all these &quot;planets&quot; or &quot;moons&quot; in sufficiently short times that they must either be travelling at relativistic velocities, or the worlds in question must be very close together. Yet the worlds must have relatively stable orbits [and so can&#039;t be that close together], or there&#039;s no way in hell you could terraform them. Assuming you accept that terraforming is even feasible, never mind in the absurd timescales described [even if they did all miraculously have about the right mass]. And if you were investing sufficient resources to terraform a planet in a few years or decades, does it seem reasonable to leave the exploitation of that vast new resource you&#039;ve just created to a bunch of dirt farmers? Who can somehow afford to have livestock transported across space, but can&#039;t afford a diesel generator or a half-decent machine shop? And don&#039;t get me started on the artificial gravity, which continues to work even when all power, including basic life-support, is gone. Oh, and chance close encounters in deep space? Close enough to risk &lt;i&gt;collision&lt;/i&gt;? Orders of magnitude less likely than winning the lottery.)

Me, I think Farscape took the right approach: &quot;We know the science doesn&#039;t make sense, and we don&#039;t care. It&#039;s &lt;i&gt;fiction&lt;/i&gt;, guys.&quot;</description>

		<description>Given your statement:
&quot;But I love taking the opportunity of someone else’s error to actually do some real astronomy education.&quot;

then perhaps in the future you can include some proof reading?

&quot;the utter layers of the star explode outward&quot;

Hate those &quot;utter&quot; layers....and do things often explode inward?</description>

		<description>And kudos to Utakata for finally bringing in mention of the Sailor Scouts to this blog.  Although my personal favorite is, and always will remain, the incomparable &lt;i&gt;SAILOR MERCURY!&lt;/i&gt;  Mizuno Ami, the babe of all babes.</description>

		<description>I think Bellatrix is white rather than blue, although I certainly don&#039;t recall its B-V value offhand.

Large blue suns may have large &quot;habitable zones,&quot; but since they last so briefly, they don&#039;t have time for any of their planets to produce oxygen atmospheres.

And as for negatrons...

According to Darkwing Duck, positrons and negatrons are the basic particles of good and evil.  (&quot;I learned that in school,&quot; says Gosalyn.)</description>

		<description>Blue Sun was a corporation, not the system&#039;s name.  Although that doesn&#039;t mean there&#039;s not a blue sun in there somewhere.</description>

		<description>What are you trying to pull, Phil? If you ever cared to do a bit of careful research you&#039;d learn that black holes could easily sneak up on us unawares:

Rimmer: ...But a black hole is a huge impacted star. It&#039;s millions of miles wide, it&#039;s massive! Why didn&#039;t you see anything on the radar screen?

Holly: Well, the thing about a black hole, its main distinguishing feature... is it&#039;s black. And the thing about space, the colorof space... your basic space color... is it&#039;s black. So how&#039;re ya supposed to see &#039;em?</description>

		<description>&gt;Joss mentioned somewhere or other (handwave handwave) that all the &gt;events of Firefly happen in the one solar system. Something about that &gt;popped up in the movie, where they explained that it’s a system with a &gt;lot of gas giants with habitable moons or something. Probably multiple &gt;stars, weird orbits and so on. Specifically, he said there’s no warp drive in &gt;use anywhere in Firefly, so it’s all happening at what your mancrush &gt;friend Wil Wheaton would call “impulse speeds”.

&gt;So there you go.

Agreed, but that isn&#039;t exactly what TBA said above.. He said Joss confused the solar system with the galaxy. What you are saying, and what i&#039;ve gathered, is that the entire show takes place in just one solar system. Though i don&#039;t think it has multiple stars(well, never stated one way or the other in the show).

But that is an artistic choice by Joss, that is not him confusing the solar system with the galaxy... hence my confusion</description>

		<description>Utter layers of a star? That’s utterly ridiculous, man.

Also, I may be corrupt, but I ain’t little.</description>

		<description>Yeah, there&#039;s a map of the Firefly star system floating around.  It&#039;s an open cluster with... I want to say six or seven stars, and lots of planets and moons amongst them.  I don&#039;t think there was any confusion about it being a galaxy; the closest I can think of was the emptiness that they said turned people into Reavers, but there&#039;s plenty of empty between star systems that can fit that bill.  And those are just folk tales, of course.</description>

		<description>I was kidding about the &quot;ebiggen&quot; thing, by the way; I actually like that &#039;word.&#039;
So, I guess this might be the time to admit that Space: 1999 had a strong influence in why I studied astronomy every chance I could get... seriously, I loved that show when I was a kid (and still am a fan of its first season), and wanted to know more about the real moon, solar system, the universe in general. What I discovered is that the universe is even cooler than what I&#039;d watched on tv, but that show in particular kicked off my lifelong interest! (And the Eagle is still one of the coolest sf spaceships designed, ever.)</description>
