How are you quoting?

No, it would not.
This problem is about the hydrostatic equilibrium of a self-gravitating sphere of water. Let's take:
According to the last equation here, we have that:
dP = g(r) rho(r) dr
Water under great pressure does compress, but just to make things easy, let's assume it doesn't. This makes rho=1000Kg/m^3, a constant. We can also use the Shell theorem to point out that g(r)=-GM/r^2, where M is the mass inside r. We have thus:
M=4/3 pi r^3 rho
dP=-4/3G pi r^3 rho (rho/r^2)=-4/3G pi rho^2 r
Now we integrate this from R to 0, and determine that the pressure at the centre of a planet of radius R is:
P(R)=2/3G pi rho^2 R^2
The radius of earth is roughly 6371Km, which means that if it were made entirely out of water, the pressure at the centre would be about 5.67gPa. Now take a look at this phase diagram for water and notice that at this pressure, and for any temperature roughly between 0 and 100C, water is in the Ice VII phase. Which is solid.
Thanks to rpenner here. Why can't I get fucking rho and pi to display?
You jest, but are entirely right. Quoting the article quoting the Federal Review Board for something:
This applies to, for example, media that contain indecent, extremely violent, crime-inducing, anti-Semitic or racist material, also to media content that glorifies National Socialism, drugs, alcohol abuse, self-inflicted injury or suicide, to media content propagating vigilante justice and to media content that discriminates against specific groups of people.
There is no way that doesn't include Wagner.
With all the fancy scientists in the world, why can't they just once build a nuclear balm?
