I read an elektor article that claims faster then light comms.
So much so it claims an led is lit 400mS before you press a button to turn it on.
The process uses ulf Rf frequencies and only a few standard parts as well as 400m of cat 5 cable.
Being an april edition it sounds like a fools joke to me.
 
That would seem to be a fair assumption.

Lighting the LED before you press the button isn't faster than light, it's prediction.

What if you change your mind about pressing the switch after the LED turns on?

What if it doesn't let you change your mind to prevent you from interrupting the time-space continuum?
 
Weird innit.
I dont believe it enough to go and get the solder iron.
