@cassolotl@cybre.space: wormholes are one-way.
Me: How do you know wormholes even exist?
Cassian: because you can see them, they are like a black dot because they suck all the light in.
Me: that's a black hole.
Cassian: a wormhole is when you have two black holes that are connected.
Me: I think you may be conflating science fiction with science.
Cassian: I would never.
