Just to be clear; wormholes, as a thing, is a result of theoretical calculations, allowing them to exist. The existence of wormholes might also "help" some calculations make sense. So it is a mutual relationship between the calculations and the idea of a wormhole.
In reality though, wormholes does not exist, and by any means does not make sense.
However "wormholes" can be something else, and therefore exist anyway - as something else than a portal to another time and place.
More on that subject on a later time.
