The northern Quarken is covered with traversable ice every third or fourth year.
If XmNinitialFocus is NULL, the first traversable non-tab-group widget that is not contained within a nested tab group receives focus.
Now, you might think, remembering your school physics, that this completely rules out the possibility of constructing traversable wormholes.

Intense dryness pervades the atmosphere during nine months of the year; but little snow falls, and the western passes are so little subject to intermittent falls of fresh snow as frequently to be traversable during the whole year round (see Ladakh).
