Re: civilization

I personally think, that if we're basing the development of a civilisation, that it be based on several criteria, not merely energy consumption-- Namely, the balance between adaptation, conservation and consumption. The truly-high civilisation will attempt to get the most maximum bang for the most m...

Re: I Suggest a revised definition of "planet"...

Particularly since Sedna has not shown any significant icy content in the reflective spectrographs that have been analysed.. And you're right- There are at least 3 classes of planets that we know of in our Solar syste- Rocky, condensed-gas core (proto-stellar) giants and solid-core gas giants. We're...

Re: I Suggest a revised definition of "planet"...

What I don't like about this is delimiting based entirely on non-scientific bases.

I strongly prefer the mass-accretion definition of a planet.
(Note that I said mass, not gravity.)

Re: Possible Problems with Celestia and Windows Vista!

er...just two quick questions here: what is Solaris, what is so great about Mac, and are either free? Solaris is Sun's workstation OS. It's Unix-like, but it's not Unix or Linux. Until recently (ie: with version 9 or 10) it had been commerciual, like SCO Unix, but now it's free to download, or you ...

Re: Possible Problems with Celestia and Windows Vista!

Depends on the software you're using. Some might have simple license migration programs, while for others, you could look into alternative applications that can work with your existing files. There is very little I have found on a PC that I can't do on a Mac, thankfully! (I'm no gamer, though, be th...

No, no... There's just one planet- the Earth. The rest are just wantering points of light in the sky, except for the Sun and Moon.

Re: I Suggest a revised definition of "planet"...

First off, I agree with the gravitational condensation definition for a planet; otherwise we'll end up trying to discuss whether or not even large sub-stellar orbitals (ie: gas giants) are even planets, based on whether or not the planet even has a core of any kind! (Sounds ridiculous, but think abo...

Re: Here is the "REAL" tenth planet of Solar System

Or that it could have, but being so far away from the greater influence of the Sun, it was able to attain some influence from the Galactic Plane, perhaps, but still locked into orbit with the Sun. It's a fair bet we'll see Solar influence out to at least 1000 AU- None of the new worlds are that far ...

Re: I Suggest a revised definition of "planet"...

You sure about that? Mercury has a large iron core, yes, but its mantle and crus are solid, meaning the planet is technically cold. I'm unaware of any Mercurian magnetic field. Mars' core has also gone cold, similarly, and any magnetic fields are localised near the surface. There have been no geolog...

Re: Possible Problems with Celestia and Windows Vista!

There are actually several different open-source and free-software licenses in use, such as Creative Commons, a number of them address some of the limitations of GNU's GPL, which did start the ball rolling over 15 years ago.

There are always alternatives.

Re: Here is the "REAL" tenth planet of Solar System

Is there a name for this new body yet? Yes! They decided to stop calling planets after roman gods. Instead they will call them after comic-characters from now on (well, fact is, the started already with Pluto). As of the '313' this planet will be called 'Donald' because this number is connected to ...

Re: Here is the "REAL" tenth planet of Solar System

Actually, I just thought... If the IAU does commend 2003 UB313 as the tenth planet, and gives it a name, what will the astrologers do: Many have already incorporated Sedna. Some already have Ceres, Pallas and Vesta. Even a few have already incorporated Cruinthe into their celestial pantheon. d.m.f.
