While we see wormholes in fiction all the time, they aren't always addressed as Einstein-Rosen Bridge. At this time, there are two examples in my mind which used exact term Einstein-Rosen Bridge:
In Thor: Ragnarok (2017) movie, Banner addressed Devil's Anus as Einstein-Rosen Bridge.
In an episode of Justice League (2001) or Justice League Unlimited (2004) TV series, Flash ran at lightspeed on Green Lantern's track to create a wormhole near Sun to suck something out of Sun. Here, Batman or someone in Justice League used the term Einstein-Rosen Bridge.
When was the term Einstein-Rosen Bridge first used in Science Fiction?
