(With apologies to Shakespeare)
"Double, double toil and trouble; Fire burn and cauldron bubble."
— William Shakespeare, Macbeth (1606) act 4, scene 1, line 14
The 2003-02-15 issue of NewScientist has an article titled "Our Universe in glorious detail" on pages 12-13, about results from the Microwave Anisotropy Probe (MAP). On page 12 is a small sidebar "Our Universe: The Facts", which contains (among others) the following two items:
- Age: 13.7 billion years
- Hubble constant (expansion rate): 71 km/sec/megaparsec
Since I'm interested in pregeometry (a term coined in the 1977 paper "Is physics legislated by cosmogony?" by J. A. Wheeler and C. M. Patton, and meaning "...something deeper than geometry, that underlies both geometry and particles."), I wondered what the above would entail at the Planck scale.
