Well, GM I hope you use the list I gave you
WHich I stole from you :3

[Xantalos]

+1 for everything involving no star

What if we're on a large moon with a large atmosphere that orbits so close to a gas giant that the atmosphere of the moon blends with the atmosphere of the other. Like, there's just a continuum from one atmosphere to the other. So you could fly a jet from the moon into the upper atmosphere of the planet.

Or would that just result in tons of atmospheric drag that would quickly send the moon crashing down into the gas giant?

[10ebbor10]

You can't go into orbit willy nilly. There are certain constants that need to be abided.

In order to go that low, the moon needs to be
    -A: Very,Very light (Likely to be blown out of orbit by a sudden wind gust.)
    -B: Very,Very Fast (Friction)
    -C: Have a positively huge gas giant (Friction still kills it)

Also, gas pressure will automatically spread out, so you can hardly go from high pressure, to low pressure (high atmosphere), to high pressure.

I think you actually could if you take gravity into account.

If you stood on the moon's surface facing the gas giant and flew straight "up" (ie. towards the gas giant), the atmospheric pressure would be relatively high near the starting point on the surface, then as you get further from the surface of the moon, the atmospheric pressure would steadily decrease until you reach a point (The L1 Lagrangian point, I believe) where the atmospheric pressure would start increasing because of the gravity of the gas giant.

But yeah, I'm not sure you could ever form a stable system like that due to friction from atmospheric drag. Could it maybe be unstable, but last for a few million years?

[10ebbor10]

Gravity is not a very strong force at those distances. Besides, the L1 point would lie pretty close to the lunar surface. You won't really have a significant difference in athmospheric density.


I don't give such a system more than an hour. This is, for all points and purposes, a meteoroid barreling into a hostile atmosphere at a very high speed. Most likely, the moon'll break up under the tidal stress, burn up, or simply crash.

Since there haven't been any other sense-making planets, KAON IT IS. Suggest what you want to start out as!

[wolfchild]

Something fairly basic, give us an opportunity to take it pretty much any direction

more like a flat blob than an amoeba. Getting out of the unicellular stage generally takes ages...

Right, right. This.

Wait, what is Kaon? Is it the one with no star?

It's the orbitless one, but there's enough stars so we won't freeze.

Aw. That's less of a challenge than an ice world.
