I always thought that the centre was molten. There was something on the TV
in the UK a couple of weeks ago which seemed to indicate that the centre is
actually solid, although around that it is molten.
I did not see it all and was only watching bits of it, but it would appear
some female researcher had proven this. The proof appeared to be based on
the time of travel of shock wases from earthquakes and the different speed
they travel through solid and liquid.
