07:38 <G-Mobile> eggoraptor, if you had an earth radius ball of water, what would the middle do?

11:44 <egg> where is your ball

11:45 <egg> temperature is probably going to matter?

13:15 <UmbralRaptor> I want to say that below about 1000 km from the surface it'll be solidish even if hot.

15:23 <egg> hmm

15:24 <egg> damn you phase diagram, why don't you go hotter https://upload.wikimedia.org/wikipedia/commons/0/08/Phase_diagram_of_water.svg

15:24 <egg> hm http://ergodic.ugr.es/termo/lecciones/phase.gif

15:25 <egg> O_o https://cdn-images-1.medium.com/max/800/1*m_pTi_VkcpWrHt4nCS76GA.png

15:26 <egg> it goes liquid again from supercritical fluid at high enough pressure? O_o

15:32 <egg> StochasticRaptor: so from that last diagram we have a fluid until above ~30 GPa at 1000 K; inside the Earth the pressure should be ~30 GPa at 1000 km (and it's quite hot there too)

15:32 <egg> StochasticRaptor: so maybe you can get screwed-up fluids all the way down?

16:52 <DeterministicRaptor> Not sure it'll be hot enough at depth over the long term.

16:56 <egg> DeterministicRaptor: what if it's heavy water

16:57 <DeterministicRaptor> Spiked with uranium?

16:57 <DeterministicRaptor> Or are we aiming for multiple Jupiter masses of water? >_>

17:23 <Greys> we're aiming for earth radius

17:35 <egg> DeterministicRaptor: Greys: ok, so I guess it won't get very hot

17:36 <egg> Greys: how far is it from a star

17:37 <egg> DeterministicRaptor: also one jupiter mass would be enough for things to remain hot over the longish term

17:37 <egg> DeterministicRaptor: [periodic reminder that jupiter is hot]

17:37 <egg> jupiter is weird

17:39 <DeterministicRaptor> The weirdness greatly increases in the brown dwarf regime.

17:49 <G-Mobile> earth orbit, earth star

17:49 <G-Mobile> utter destruction?

17:52 <DeterministicRaptor> Longterm hydrogen loss, probably.

20:23 <DeterministicRaptor> Which will make the environment rather weird. Possibly small amounts of free oxygen.
