Oi. The great weakness of academics is the obsession with semantics. Debating the words used is a poor subsitute for exploring the concepts.

The experimenters are clear their ‘wormhole’ is a computational “hologram” of a one-dimensional wormhole. These operational words are the concept.

This was a computational experiment designed to show something akin to ER=EPR, or the idea that entanglement is equivalent to a wormhole, an ER bridge. Its a fascinating line of inquiry into what makes the stuff of our universe, and hopefully a few laypeople get to learn about it because of their work.

This was never an experiment about the wormholes of science fiction, if that is how people read the headlines.
