By way of illustration, I recall reading a short story where
telepathic twins were part of an experiment to test if telepathy might
be a way to communicate FTL. One was "volunteered" to go into a black
hole, and the other stayed beyond to record their telepathic
communication. As the first twin approached the black hole, the
second twin "heard" the first twin's thoughts getting slower and more
incoherent, but just as loud as if they were in the same room. At the
end of the story, the second twin could only hear the first twin
scream in agony, forever.
