Wormholes are entirely speculative and need exotic matter with negative mass to exist. According to the optical Raychaudhuri's theorem, which describes the motion of nearby matter in curved spacetime, this requires a violation of the averaged null energy condition.

That is, wormholes defy mathematical boundaries of spacetime being positive in any particular region. Importantly, Einstein's field equations can yield unphysical solutions or things like closed timelike curves that create causality paradoxes and other strange phenomena.

I've got one wandering around my home and workshop that finds the item I'd like to use in a few minutes and sends it to another random place in my home or workshop but two days in the future.

Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are allowed as responses to this comment. Any anecdotal comments elsewhere in the discussion will be removed and our normal comment rules apply to all other comments.
