Venus is so inconsiderate. It presents itself as a sister world, one that would seem at first glance to be very Earth-like, but… on closer examination it’s utterly hostile to life as we know it. Surface conditions would be extremely challenging for terrestrial life, what with the toxic atmosphere, crushing pressures, and blast-furnace-like temperatures.
That’s at the surface, however. Just fifty kilometers above the surface, there is a region with terrestrial pressures and temperatures, a veritable garden of Eden where an unprotected human would not be almost immediately incinerated but instead would expire painfully (in just a few minutes) due to the lack of free oxygen and the prevalence of toxic gases.
Artist s conception of travel through a wormhole (Credit: NASA)
Wormholes and other means of providing instant access between distant fixed points are narratively convenient. They make it possible to get characters from point A to point B without dying of old age en route. Wormholes (or their equivalent) constrain interstellar travel so that, for example, people cannot simply flee combat by going FTL, nor can they emerge above a planet before their photons arrive to carry out an unstoppable bombing run. From an authorial perspective, such constraints are very, very useful.
Once their attention had been drawn to wormholes some time in the 1980s, authors leapt on the chance to use them in fiction. See, for example, how frequently the phrase appears in American English.
