> and we don't currently know how to make a wormhole, but we know they're physically possible I'm not aware of any actual observational evidence or even strong theoretical prediction that wormholes exist or that they are physically possible. Some parameterizations of our models don't rule out their existence, but it's all hypothetical. Including the question whether they are traversable.
