It’s easy to grumble, perhaps with some justification, that Pre doesn’t answer questions. However, I think that when he does it is important to recognise that fact, and to make an appropriate response.

Pre, a little while ago you posted a helpful response regarding the possibility, or otherwise, of convection occurring because local temperature inversions might have happened within the mantle. It was not my intention to ignore this; the trouble is, I can’t find it now, and I don’t want to risk misquoting it. It had to do with the combined roles of heat and gravity in determining density.

Hunting time is at a premium at present, so any help that anyone can provide would be appreciated. There are at least 5 threads it could be in.

There never was nothing.
