6.3 Wormholes

Wormholes are constructs of theoretical physics that, like a tunnel, represent a connection in spacetime. With their help one could travel through space and possibly simultaneously through time (cf.: Vaas, p. 167 f.). The name is somewhat deceptive, because a wormhole is not empty like a hole, but consists of space (cf.: Vaas, 2013, p. 178). In 1935, Einstein published an article together with the American physicist Nathan Rosen, which proves that the GTR allows wormholes, then called "bridges" (cf.: Hawking, 2018, p. 205). Its name was coined by the American physicist John Archibald Wheeler. He called the objects wormholes because he compared them to a worm crawling through an apple. The path or channel through which the worm bites its way is similar to the idea of a wormhole (cf.: Vaas, 2013, p. 166).
