Also, i am wondering if there is any direct laboratory evidence to support that liquids cannot exist at these supposed temperatures and pressures? | |

May 12, 2015 at 23:31 | comment | added | dmckee --- ex-moderator kitten | Hmm ... good point. Not sure that I have the answer. The p-wave propagation tells us about the speed of sound in that layer, which casts some light on the density. I think that Sebastian is closer than I am there: the magnetic properties of the deep Earth combined with the density may be the strongest route but I am now officially outside of my area of competence. | |

stray "are separately" that confuses the reader...
