abstract
The spherically symmetric accretion of dark and phantom energy onto Morris-Thorne wormholes is considered. It is obtained that the accretion of phantom energy leads to a gradual increase of the wormhole throat radius which eventually overtakes the super-accelerated expansion of the universe and becomes infinite at a time in the future before the occurrence of the big rip singularity. After that time, as it continues accreting phantom energy, the wormhole becomes an Einstein-Rosen bridge whose corresponding mass decreases rapidly and vanishes at the big rip.

Wormhole Modeling Supported by Non-Exotic Matter
Applies the f(R) = R - μ Rc (R/Rc)^p model and shape function b(r) = r log(r+1)/log(r0+1) to Morris-Thorne wormholes and analyzes energy conditions for non-exotic matter support.
