Apparently Albert Einstein said “…for us physicists believe the separation between past, present and future is only an illusion, although a convincing one.” (H/T Armstrong Economics.
This is an important idea because if the past, present and future are essentially human constructs, the product of thinking, then that will have profound implications on our understanding of geology.
Which means that the only reality is the here and now, which leads to the insight that if this is so, then life is, with no start and no end.
And on a quite different topic Malaga Bay’s Tim Cullen is posting some interesting stuff on Liesegang Cavities, Geodes and lunar hollows here.
I must confess to having believed in the hollow-earth idea when a callow youth working for the New South Wales Geological Survey during the late 1960’s; I am occasionally reminded of it.
And when the facts change, I change my mind, so Tim’s posts on hollow rocks and a hollow moon prompts a rethink, especially when he points out that it was updated seismic modelling that progressed the early evidence of a hollow seismologically ringing moon to its present day description of a solid iron core etc, The Ringing Moon post .
I say this because during the last 10 years of my professional career I have encountered too many geophysical anomalies from numerical modelling that when empirically tested were found to be flat out wrong. So when NASA scientists reckon that the more refined seismic processing confirmed an earth-like core in the moon, when before the evidence pointed to a hollow, ringing, moon, then one starts to wonder whether the hollow earth model has any basis in physical reality. And more pertinently whether existing seismic modelling of the earth’s interior is accurate.
Of course we can’t have a hollow moon because that would be contradicted by the solar accretion model, self gravitation and other geophysical or astronomical illusions, including the idea of planets and moons being the end products of a plasma Z-Pinch star formation process.
For the moment I am stumped.
