If you’re openminded enough to listen to those who disagree with the standard model,
take an elastic band and turn one end. Instead of the band turning, you’ll have a twist in your band
and it takes time to unravel the twist. That’s what will happen to the stick and this travels at lightspeed,
because this is what light does. Light works like ‘the stick’ in your example.
And if you try turning it faster the ‘elastic band’/stick/‘atom on the other end’ starts breaking.
If you need FTL communication, then use gravity…somehow.

Probably quantum entanglement, which we (and certainly I) don’t fully understand yet
I think the standard model says the same thing, tbh…
Gravity waves doesn’t go faster than light though?
Iirc from the 2 YouTube videos I watched light can theoretically bend thanks to gravity, black holes anyone?
Space bends due to gravity. Light continues in a straight line through the now non-linear space, thus appearing to bend.
Gravity bends spacetime, light always goes in a straight line, bent spacetime means straight lines can be curvy. That all checks out.
But none of that helps you with FTL communication.
