Terran fortnight, Martian or registered with Betelgeuse 5? And in *some
STATES!* apparently there is in use an archaic measure for the furlong
which varies by .000002 % which I suppose is within your precision and
the "give or take"... I'm guessing the furlong is still 10 chains, 220
yards but their chains or yards vary? The wear on the end of the
"chains" could account for more error than that, not to mention
manufacturing variation!
"The nice thing about standards is that we have so many to choose
from"

Andy is also known for:
"Never underestimate the bandwidth of a station wagon full of tapes
hurtling down the highway."
But I think it needs to be updated to Minivan or 9 passenger SUV.
In the spirit of "will it blend?" and "how much is a buttload?" I
have to ask, what is the speed of light in "furlongs per fortnight?"
- Steve
So it sounds like during the expansion phase a lightyear was still a
lightyear but growing bigger? If you were there how would you
tell? My platinum standard meter bar is now a longer but still
standard meter bar? Has time dilated as well? If so what does the
age of 13.5by mean? In what dimensions could you measure these
changes? [Confusion may be an understatement.]

"Because of the changing rate of expansion, it is also possible for
a distance to exceed the value calculated by multiplying the speed
of light by the age of the universe. These details are a frequent
source of confusion among amateurs and even professional physicists."

Regardless of the poetic 'outer edges' is it possible what

where the radius is time and is 13.5 by? The center being when
the big bang occurred. Then the furthest object would be
diametrically opposite and hypercircumferentially at 13.5*pi
bly or 42.4 bly away? So in the 'now' being at 30bly away is
chicken feed.

Where is "the outer edge of the Universe" and what sort of
observation would locate something there? All that the
original report in Nature established was redshift (7.51), age
(700 Myr after the Big Bang), and a surprising rate of star
formation (330 solar masses / year).
