Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Carl Sagan
Standard cosmological time, possibly without beginning depending on cosmology.
Space
Carl Sagan
Vast, general-relativistically curved.
Matter
Carl Sagan
Standard substantival matter; "we are made of star-stuff."
Observer
Carl Sagan
Plural physical observers; reverent-humanist stance; no metaphysical agency.
Energy
Carl Sagan
Standard physics.
Information
Carl Sagan
Information conserved at the world-scale; personal soul not.
Internal Tensions
Where each persona's working synthesis strains against itself.
Sagan's television persona was charged with sentimentality by some scientific colleagues (notably, his National Academy of Sciences blackball in 1992 was attributed to perceived populism). The Pale Blue Dot framing — Earth as a mote of dust in cosmic perspective — has been read as humbling and as evasive of moral urgency on the planet from which the photo was taken.
