The metric is spherically symmetric, static and transversable in the sense introduced by Morris and Thorne, with an exponential deSitter scale factor multiplying the spatial part
, where:
— cosmological constant
— redshift function has no effect
— shape function choice 1
— shape function choice 2
— throat size
— location of the throat
Coordinates with bar correspond to embedding space and "scale" exponentially with time.
—
in terms of
, embedding function in choice 1
— ensures that this ratio is time-independent in choice 1
— ensures that this ratio is time-independent in choice 2
— the usual "lift" function and embedding function in choice 2
