ROFLMAO

Good one Puke.

Actually, Jupiter's surface gravity is about 2.5 G's due to its high density. Saturn, Neptune and Uranus, OTOH, are between 0.9 and 1.2 G's or about Earth normal. The high G worlds would be huge rock and ice planets not gas giants.

Um, where did you get that 'surface gravity' information? I hope you realize that gravity is a function of mass, not density. There also is absolutely no scientific information about the 'surfaces' of any gas giants, just theories.
Also, to whomever made the comment about liquid being denser than solid, you are incorrect. Some solids, based on their freezing processes are less dense than their liquid counterparts (like water). But for most elements and compounds, solid is the densest state.

From my old high school chemistry days. I think that you meant "specific" gravity that I used. And again I'm not sure if that is the correct term to use. However, what I meant was that since things like iron are more "dense" than other things, the more "dense" elements / compounds should be at the center. Its what makes steel float in mercury.... That should IMO rule out the "diamond core" theory unless carbon is the "densest" element in the planet's composition.

Do you work for NASA?

Well, uh, you could use a search engine such as Yahoo and search on "planet surface gravity" or something similar and look at one of the thousands of references. Oh, and it absolutely is a function of density. Read one of the references.

If you're talking realism...
How do hydrogen /methane/ CO2 breathers invent fire? + how do ice planet dwellers invent fire?
How do gas giant dwellers (The colony base pic looks like it is hovering somewhere in the upper atmosphere) invent anything?
You can't mine iron without VERY LONG drill bits and of you can't make very long drill bits without carbon steel.
