I also noticed the "centre" spelling, did a quick DDG search. Got a BBC graphical website that shows factoids as you scroll down a notional descent to the center of the earth.
While there were several interesting bits including the depth of a couple of known DUMBS and a few other things, the only two interesting bits that I found were at the very bottom and one other.
The bottom said (summary) congrats you made it but the pressure is overwhelming and you were cooked long ago.
The other was "hen's egg has cracked at 234 atmospheres"
weird b/c a hen's egg can only support 3 to 4.5 lbs of weight before it cracks. That's a static load-on-one-side type test, not uniform pressure all the way around, so not entirely valid as a comparator.
Did a quick search for the hen's egg thing and didn't find jack, but I didn't look hard at all.
Mean something to anybody, or just some physics so irrelevant that it won't come up when you goggle it?
