Re: Very impressive.
Very impressive indeed. However, my understanding is that we see pulsars because we happen to lie within the path of radiation that is emitted as it rotates, ie, they don't radiate in all directions.
I therefore wonder how far we would need to travel before we are no longer aligned with a particular pulsar's beam and it effectively goes 'out'? The solar system is probably covered, but i would guess that 10's of light years wouldn't be.
Chances are we would begin to see different, new pulsars as we move further out, but wouldn't we need to know their position with some degree of accuracy before they could become a new reference point?
