what are these wormholes that some claim to be trying to make or, at least, simulate? The Maldacena equivalence implies that an Einstein-Padolsky-Rosen entangled state of two quark/gluon/etc field theories without gravity, suitably chosen, is physically equivalent to an Einstein-Rosen bridge joining two suitable black holes in a string theory on an appropriately curved space with more space dimensions than the field theories have.
