摘要：
We present here analytical solutions of general relativity that describe evolving wormholes with a nonconstant redshift function. We show that the matter that threads these wormholes is not necessarily exotic. Finally, we investigate some issues concerning the weak energy condition violation and human traversability in these time-dependent geometries.
