The PlaneShift World

[Zephyrus]

I did a little bit of hollow planet in physics; it depends how far down you are. Because you will be pulled to where most of the mass of the planet is. If that is beneath us then gavity pulls down, but if there is more mass above you then you will be pulled up (towards the surface).

However, for a stalagtite to piont down like that you need downward gravity to pull the water that forms it. So in short yes will will have gavity but it will be slightly less than on the surface.

But from talads description, you would be pulled to the cieling, and the stalagtite couldnt exist. Because if the center is completely hollow, most of the mass *is* the suface. I guess thats what happens to physics when gods get involved...

I am more curious why it doesnt cave in, and why its not full of molten magma  ?(

[karakth]

Mmm perhaps using what whemyfield wrote in the RP forum, we could say that the planet is \"A dead, hollow husk of what it once was\"?

[Zephyrus]

But there would be so little gravity if it is hollow, because there would be next to no mass... Unless the planet is much much much bigger than earth or made out of a very very very dense material. Other wise there would be no atmosphere as the gases wouldnt be pulled down and kept in the planets gravitational field.

Like i said, physics says bye bye when gods are involved.

[Zephyrus]

Under the physics we understand, using talads description the planet would look something like this:



A&B: You would be pulled to the sides of the cave except if you were right in the middle, where you would float.

C: The water wouldnt \"fall\" either way, not unless the mass of the stalagtite or the patch under the lake was absolutely massive, i.e. some super dense material; osmium

D: people inside the stalagtite would be either pulled towards the surface (the ceiling), or the sides of the stalagtite if they had enough mass.

and finally E: the crystal would i imagine act like modern day fibre optics, refracting light at the angle of incidence into  yliakum

Remember that there is magic. There may be other forces controling things.

Hmm...

I was under the impression that the stalactite and the massive cave were all part of a much larger planet, in which case the physics/gravity would all work out fine. So that hollow area makes up the *entire* planet?

In any case, seeing it visually really helps it sink in even more than the description did. Looks very cool! Very unique concept.. I can\'t say I\'ve ever seen any setting quite like that before.

Nice!

Let\'s do this the easy way, shall we?


<-- World

1) Turn it upside down.
2) The blue stuff is massive ... planet... and the white stuff is cave and stalagtite.. mite... Whatever it is.

Therefor my logics say that no matter where you are on the planet, you get pulled down. Am I right, or is there some kind of physician present who can clear up the details? Hmmm?

[DepthBlade]

Good Job Zephyrus ! Yours is the best of them all

[lynx_lupo]

Grono, Zephyrus is almost right. But so is Xordan.

And remember people, even Yliakum is so big we\'ll be discovering it for ages. Then ask yourself why it\'s called planeshift.

the mass center wouldn\'t be in the cenetr of the planet anymore...

[karakth]

Bah magic nothin\'. Magic is fine and all but it will get really boring after a while if you keep doing impossible stuff and then saying \"Uh...Magic?\"

Since the Graphics Engine simulates physics on Earth, the ratio of physics laws to magic have to be at least 6:4 (or 60% Physics, 40% magic), IMHO.

[Kiva]

karakth - Since when has a 3-4 feet tall dwarf been able to jump about 1 1/2 his own height on earth? That seems just a little impossible, unless I\'m just completely mistaken.

About the magic stuff. Well, who says we ever get to know how the world is put together? And honestly, why do we even care? Is it really true that the community has become so bored that we discuss the smallest things about the game, such as \"How do the physics of PlaneShift work?\" It\'s not right, people. Get over it. The game works, and that\'s all we need to know.

[karakth]

We\'re only bored until CB comes out

And I think the dwarf jump is a glitch. Hmm someone should fix it. Dwarves shouldn\'t be able to jump so high, or they\'d be fleas

Besides, people always start discussing the physics of a make-believe world (like the \"a dragon can\'t fly\" argument in DnD).

Although when you think about it, our RL world is held together by magic too. Well, particles are held together by magic. Why do two opposites attract (electrons and protons)? Dunno.

The wizards of this world are Quantum Physicists, IMO.

Virtual exchange particles, in the case of the electromagnetic force (electrons and protons as you put it) that is photons

Nowhere in the whole history does it say that the larger cave  is as large as the whole planet. It only says that it is three times larger than Yliakum.

However, after reading the entire history this afternoon, and talking with Talad, I saw I was completely wrong

for example, the cave is actually hundreds times as big as the stalactite(\" Laanx wandered into a cave that was hundreds of times bigger than the one he created, where beings without a name dwelt. At the middle of the cave, he saw a deep lake full of life, whose shores were a fertile soil.\", with \"the one he created\", I think he\'s referring to Yliakum)

Then, while talking to Talad, it got even worse
He told me that even on my map, the cave was too small, it could go completely through the planet  and cover the whole center of the planet too. (yes, I think this is a really weird idea too, and I say we don\'t discuss this but just let this rest untill CB is finished and then try to find out how it really should be.)

I think that we, for now, should use Ripostellar\'s map, with a larger cave as reference to how the complete world should look like.

Seeing as Talad is the head honcho... thats why i think the world is hollow...
