A recent article mentioned a gas jet from a quasar (wasn't it a galaxy,
though?) as an example of faster than light transmission of signals.
This example is not necessarily a case of something actually moving
faster than c (a signal, or whatever). On possible explanation that
I have seen for this phenomenon is analogous to what happens when you
shine a flashlight on clouds and move it quickly from one side of the
sky to another. The apperant velocity of the spot is very high, but
the actual movement that takes place is really quite small. Well, I
don't know if this is useful, but I just thought I'd mention it.
