path of light through expanding space, question
this question ought to be directed generally to whomever might like to help with an explanation
if a quasar is observed with redshift 1.7 or more then at the time it emitted the light we now see the quasar was receding at speed of light or faster
question how did the light ever make it here since it was initially swept back.
I have a vague notion but it still remains paradoxical and unintuitive to some extent. Maybe I could give an explanation
or pass along one I've heard. But I'd rather hear someone elses
take on it.
Im thinking of the teardropshape lightcones in eg. Lineweaver article "Inflation and CMB". assume you know article if not I'll give link
apologies for having initially directed this to Nereid since it is really an open question. I've tried to erase the thread so as to remove the title, but computer won't let me erase it at least for the moment
