: Last week, we talked about the mysterious Unruh effect, in which
find themselves bathed in a sea of particles.
: ... inertial observer sees that there's a type of friction between the
and the quantum field which should inhibit that acceleration by creating ...
: But the
doesn't directly see that friction.
: The answer is that the
perceives themselves to be plowing through a bath of Unruh particles, and these produce the drag.
must expend more energy to produce the same acceleration.

: It tells us that
find themselves in a warm bath of particles.
: This means that any events happening to the left of that diagonal line will never affect the
