Description
Cosmological data indicates that dark energy was phantom (w<-1) above
z=1, rapidly evolved across the phantom divide (w=-1), and today has w>-1.
These properties may arise from different dark components (a chimera) or
have a unified origin (an elephant - a single animal despite scientists
in the dark guessing a snake for the trunk, tree trunks for the legs, etc).
I describe ideas for dark energy elephants, and which falter, just as few
of Hannibal's elephants survived crossing the Alps to reach Florence.
