[Cherenkov rad.]() aside:

Why can't you arrive sooner than the #SignalFront emitted + propagating from any specific event in which you took part ? -- Simple enough:

Any receiver you met after having taking part in a specific event
can learn about this event either (at the latest) from you, as you meet;
or else even before having met you (having rec.d the corresponding signal front already).

The linked article is signed by some Don Lincoln. (There's no link given there to a mastodon account, or to any applicable Wikipedia page.)

Anyways, I fully concur with your outright assessment of that article: total crap!

Instead: The #SignalFront plainly arrives with, or before, any signal.
