       It is as established as ANY postulate (assumption) is.
       It is established by the international scientific community
       to the extent that it now has a precisely DEFINED value of EXACTLY
       299,792,458 m/ s as of October 1983 IIRC.

       only implied as far as I can tell.
       'Serious' physicists predict that tachyons will/would emit
Cerenkov type shock waves that have not yet been observed.

       Not any known to the general public
       - but Robert B Zannelli <Spinoza321@AOL.COM> seems to think so.
