But anyway, the newest breakthrough is thorium
nuclear clocks, which IIRC are 5 orders of magnitude more stable
than cesium clocks.  (And probably 5 orders of magnitude more
expensive...)

"optical clocks" that are developed to get more precise and
more stable versions of atomic clock times.

Record my prediction: it's not going to happen.
 
 

 
I don't know enough about Thorium 229 nuclear resonances to be able
to predict one way or the other.  Do you have a good reason or
reference for your thoughts here?
 

Michael's principle.
If you don't know what it means, search comp.arch archives.
