OK,
I'll bite:
From a paper by Stanek and Garnavich, using parallax distance =
measurements to "Red Clump" giants in M31 (hi AJ), a mean distance of
784 kpc plus/minus ~2 percent is derived. So I'll take 784 kpc (784000 =
parsecs) as "gospel."
So we have:
1 parsec =3D 3.08568025 =D7 10E16 meters
1 cubit =3D 0.4572 meters
cubits/parsec =3D 3.08568025 =D7 10E16 meters / 0.4572 meters =3D =
6.74908191164 x 10E16
Finally:
6.74908191164 x 10E16 cubits/parsec * 784000 parsec=3D 5.29128021872 x =
10E22 cubits
That's a pretty long walk . . .
Matt
