The doctrine that the world is made up of objects whose existence
is independent of human consciousness turns out to be in conflict.
The experiments in question were first proposed as "thought experiments," intended for the imagination only. In the past few years, however, several versions of them have been carried out with
real apparatus. It now seems that unless some extraordinary coincidence
has distorted, the results the quantum-mechanical predictions will be confirmed. It follows that the local realistic theories are almost certainly in error.

Fluids play a key role in modifying the chemical and physical properties of fault zones, which may prime them for repeated rupture by the generation of high pore fluid pressures and precipitation of commonly weak, secondary minerals. Fluid flow paths, sources and fluxes, and the permeability evolution of fault zones throughout their seismic cycles remain poorly constrained, despite their importance to understanding fault zone behaviour. Here we use geochemical tracers of fluid–rock exchange to determine budgets for meteoric, metamorphic and mantle fluids on a major compressional tectonic plate boundary.
