Statting out the earth...

[Tack122]

I at one point saw figures for how much health the earth should have, anyone know where I could find that again?

Or if anyone is willing to do the math...

[Innis Cabal]

the earth? Well its a col+ creature, and if you want it to be alive, so that would make it an elemental, so give it that hit die and what level do you want it to be?

[Cybren]

Well then again, how much of different stuffs is in the earth? If it's mostly iron, 16740551.

[Tack122]

Well having it as a creature doesn't make much sense, its not sentient nor able to move (technically but orbits don't count) so I guess it would be statted as an object.

As for the earths principle compound, perhaps there are are scientific journals on the composition of the earth.

Found one, formatting it.

silica (http://en.wikipedia.org/wiki/Silica) 59.71%
alumina (http://en.wikipedia.org/wiki/Alumina) 15.41%

Is the composition of the crust so we can assume it uses the hardness of stone. Because thats basically what all that adds up to.

[Quellian-dyrae]

Well if Wiki is correct and the earth's radius is a bit under 4,000 miles (8,000 mile diameter/thickness)...iron is 30 hp/inch of thickness...63,360 inches/mile...so...I get approx 75 billion hp.

[Innis Cabal]

so an alternate earth elemental, so its a col+ earth(iron) elemental

[Tack122]

I can't seem to find the rules for hardness on objects... I can't see the earth taken unmitigated damage from any attack so there has to be some sort of hardness or DR

[Innis Cabal]

give it DR 100/epic, that should make all but the strongest characters of your world totally ineffective

[Arbitrarity]

Or... not. The earth has crazy HP, some hardness. DR100/epic makes no sense at all.

[Drider]

Mining equipment would have to do massive damage to get past DR 100

[Tack122]

If anything DR then it should be DRx/-

x could reasonably be a thousand or more...

[Mewtarthio]

Nah, just lots of HP. You can damage the Earth pretty easily, but it'll take a long time to do so.

By the way, it's not DR; objects use Hardness.

[Demented]

The majority of the Earth is mantle, effectively lava. Apparently, you don't destroy lava; any mass of it reforms after whatever you do, barring certain effects. Voila, the Earth is theoretically immune to destruction. Likewise, the core is molten metal.

The crust is a relatively thin layer of natural stone, only a few miles thick and probably the only thing you can destroy. A 10x10x10 ft. cube of stone has 1800 hp. The 8 hardness is pitiful, but effective for protecting from most mundane attacks. The layer of loose stone/dirt that farm tools can be used on is so small as to be irrelevant.


Or, you could look for previous threads on the subject....

[jjpickar]

Actually, TV shows and movies in the 60's proved that it is fairly easy to destroy the earth. Just shoot a laser beam at it. Kaboom!

[magic8BALL]

The hardness of the earth is different in different places: 8 is solid rock, and thats the hardest parts of the earth, so anything more is silly.

HP: 8 000 miles x 63 000 inch/mile x 15 hp/inch (solid stone) is 7.56 billion hp

Keep in mind that not all the earth is stone: most of it is silica (sands) and the rest is relativly soft. So 7.5 billion HP and hardness 7 for an overall object isn't too hard...

So who wants to sunder the earth a-cleft? Anyone who can deal 7 500 000 007 damage in one attack in my book...

[Cybren]

Well yes and no. "destroying" the earth is hard considering that it would probably just recollect due to gravity anyway.

[The_Snark]

Over a geologically long period of time. And that doesn't do anything to help the Earth's inhabitants.

I think the point isn't so you can destroy the earth with an army of commoners wielding picks and hammers, it's more to see how big of an epic-level Ruin spell you need to blow up the planet.

Verbal component of the spell would have to be either "Commence primary ingition" or "Energize the demolition beams!" followed by some sound effects.

If we're going to destroy something we're going to do it right.

[Kyace]

Give it some sort of regeneration:

Massive Regeneration (Ex)
Planets heal 100 HP per round, planets can reattach severed parts instantly by holding it to the remainder with gravity.

Of course that means that with 101 robots that can beat the hardness, they could destroy a planet give enough time, but thats basically true in real life (http://en.wikipedia.org/wiki/Gray_goo) too.

edit:

Earth has an iron core for 10 hardness in places. :P

Also, quartz (http://en.wikipedia.org/wiki/Quartz), all that silica you just discounted, is harder than iron on the Mohs scale (iron is 4 on it, quartz is 7, so is roughly 16 times harder).

[lsfreak]

I don't think you can say the core has the hardness of iron, as it's *molten.* Rather, any physical object attacking it would take damage as in being dumped in lava, and probably lava that's at least twice as damaging as normal.

[Kyace]

I thought that only the outer core was molten, while the inner core was solid. Not totally sure now. They wouldn't seperate the core into inner and outer if both were liquid, would they?

[Demented]

Since nobody has been into the core, it's hard to say for certain if they're right.
Assuming they are...
The inner core is solid only because of the immense pressure. What would happen to it if that pressure was released?

There are some ideas.

[Maerok]

I'd just been thinking about this...

Colossal Animated Object: 30 feet in diameter (space it takes up); every 10 feet after is another "+".
Earth is 42240000 feet (8000 miles * 5280 feet/mile) in diameter.

(42240000-30)/10 = 4223997 "+"s

So, the Earth as an Animated Object would be a Colossal 4223997"+" Construct...

And it's HD would be like 32^4223998.

[Lucid_Archon]

I don't see any reason why a planet should have any regeneration. Am I missing something?

If you attack the ground and mess up a whole bunch of dirt, gravity just brings it right back anyway. You'd have to do a whole crapload of damage to actually make a dent.

[Tack122]

I think that DR or some insane hardness number would achieve this goal more realistically.

Such a thing makes it so that you have to do that insane ammount of damage to make the dent.(DR - Hardness)
As opposed to the gigantic crated filling up slowly or quickly depending on how massive the crater accually is. (regeneration)

[SolkaTruesilver]

You should try this website

http://qntm.org/destroy

and calculate how much damage is required based upon the mean they have of destroying the Earth.

And it's not just to eradicate what's on it. They want to destroy the astronomical body known as Earth.

[Closet_Skeleton]

Since lasers deal fire damage and objects take only half damage from fire then the Deathstar Superlaser deals 16 billion damage.
