[time-nuts] Fast than light neutrino

[Bob Bownes]

As always, the answer is 'it depends'. :)

Solid rock? Liquid rock? Gaseous rock? Plasma? :)

Wavelength?

A nice light rock like calcite it probably isn't too tough to measure.
Si02 is pretty easy too, I'm sure.

For classic basaltic or feldspathic rocks, I suspect you are going to
need something well outside the visible spectrum. At least in the
first two phases. Not to mention the issues in a non homogenous rock.
