What is a wormhole NASA?

Could you please explain what a "wormhole NASA" is? I've heard this term mentioned in the context of space exploration and cosmology, but I'm not entirely sure what it refers to. Is it a specific type of technology NASA is developing? Or is it a theoretical concept related to black holes or spacetime? Could you elaborate on the scientific principles behind it, if any? And if NASA is actively researching this, what are the potential applications or implications of such a wormhole? Thank you for your clarification.
