Pulsars each have their own frequency, so each is unique.
ALso: A convention center orbiting the Cygnus X binary system.
A more nearterm convention spot: Copernicus Crater, 2006, as was
previously discussed on the >H list last year....

Since the universe is theoretically circular, i.e. if you travel in a
straight line you eventually return to where you started, then our
universal "center" is right here, which would also fit, since its all
relative anyways, a convention of trans and post humans would be at the
center of their diaspora, Earth.
Now considering that inside a black hole, the gravitational forces are
so great that the gravity of the rest of the universe is infinitesimally
small, that couls also be the closest thing to a "center" of the
universe, even though the inside is supposedly no longer part of this
universe....hmmmmmm. Possibly Cygnus X would have a hall for virtual
beings just above the event horizon, which would be the closest you
could get without actually leaving the universe. Funny, the point
closest to the "edge" of the universe is also closest to its "center".

No but I would say that the event horizon would be the universal meeting
point, as it allows extreme time dilation, allowing the inhabitants to
live to the end of the universe, and possibly through to the next one if
it eventually collapses, or to all travel into the next universe through
the hole that may be created by the singularity they are orbiting. In
this case, One would have to seek out black holes that have beacons
orbiting them to invite passerby to join the party. Also, given this
theory, might radio astronomers find advanced civilizations broadcasting
from blackholes at extremely low (i.e. redshifted) frequencies? Perhaps
we need to find black holes that are far enough away or large enough to
have quiet natural EM bands redshifted to be in synch with those bands
that penetrate an oxygen atmosphere? Pehaps with unusual EM bands?
