Robert -
Meanwhile, I still want to know what space-time was expanding relative to!
<semi-serious> Relative to the concept of a constant (geodesic) distance
metric (in Furlongs of course) calibrated the Speed of light (in F/F of
course)? Distance == Time for Light to Travel / C . </semi-serious>
At what time (in femto-fortnights) after the big bang was our universe
roughly one buttload in volume?
Hint: conversion factor is roughly 7.56*10E-06 cubic furlongs/buttload.
Challenge: What is the value of Pi in a spherical metric space
(assuming the universe expanded from a point in the shape of a spheroid)?
Referring back to an earlier thread: Just because I don't do math
doesn't mean I can't do arithmetic!

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!

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?"

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.]

http://en.wikipedia.org/wiki/Metric_expansion_of_space:
"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
might be meant is in the context of a hyperspherical universe
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).
