Zusammenfassung
Results of recent experiment reinstate feasibility to the hypothesis that
biomolecular homochirality originates from beta decay. Coupled with hints that
this process occurred extraterrestrially suggests aluminum-26 as the most
likely source. If true, then its appropriateness is highly dependent on the
half-life and energy of this decay. Demanding that this mechanism hold places
new constraints on the anthropically allowed range for multiple parameters,
including the electron mass, difference between up and down quark masses, the
fine structure constant, and the electroweak scale. These new constraints on
particle masses are tighter than those previously found. However, one edge of
the allowed region is nearly degenerate with an existing bound, which, using
what is termed here as `the principle of noncoincident peril', is argued to be
a strong indicator that the fine structure constant must be an environmental
parameter in the multiverse.
