oh okConsider a cavity in a fluid, with a time dependent pressure p(t), the radius R(t) of the bubble is:

sheirlythat first part of the equation should just be
R-(p&-1) as dividing by P would cancel the others out....however, how can you have infinity in the equation?

he's dividing by rho, not prho is density, p(R) the pressure at radius R, p(infinity) the asymptotic limit of the pressure as R is tended to infinity

ahhh i didnt see the rhoand well explained!

Yeah I know I suppose I stole that from Rayleigh and Plesset...*wistles*

the thing on the bottom is a rho not a pand the infinity is a subscript on a p, which is like the pressure at an infinite distance from the bubble (cavity)

I've just had a sudden thoughtthat looks enormously like the equivalent of the Friedmann equation in a McVittie spacetime. I don't know what I could do with that but it might be worth looking back over an aborted project in the McVittie spacetime.... Hmmmm.
Edit: I probably mean the Raychaudhuri equation rather than the Friedmann equation, since that's the same as the FLRW case.

I'm finding McVittie space-time hard to digest*runs back to fluid dynamics*

That's painfulas is the naked singularity sitting on the event horizon when you try and chew it.

I don't know what it would be like to stick your dick in a black holethough I can hazard a guess, but I really don't know what it would be like to try and stick your dick through a naked singularity. Either way you probably wouldn't live to tell the tale.
