Not so much tachyonic though as according to "gravity's speed"
coming down or braking from the standing electrical field wave.
"... didn't have relativity in order ...", that's rich.
Article the other day, "astonishing new laser-and-thorium setup
reduces the cloud of electron-physics and enables an entirely
new configuration of experiment, that amazingly both refines
and reduces 'what we all thought' as physical constants".

[snip more blahblahblah]
You really should give direct references. <https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.133.013201>
or the press release with it <https://newsroom.ucla.edu/releases/nuclear-spectroscopy-breakthrough-could-rewrite-fundamental-constants-of-nature>
Summary:
They succeeded in exiting a isomeric resonance in the ^{229}Th nucleus
at about 8 eV, with a lifetime of about 600 second. (so in the far UV,
using a fluorite crystal that is still transparent at this wavelength)
This may be used to create a still more accurate frequency standard,
hence a clock. (eventually)
Nothing very 'amazing' or 'astonishing' about it,
just another decade of precision gained,
after a decade of hard experimental work,
