//Let's try again, sending in plain text:
//
//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 . . .
