Main Question or Discussion Point

According to some models of inflationary cosmology, the multitude of universes in the multiverse are connected by tiny wormholes that pop in and out of existence in the quantum foam. These wormholes can supposedly be formed in particle collisions. Could negative energy be used to hold these wormholes open? Or do quantum inequalities forbid this?

Also, if one were to try to enter one of these wormholes, would he survive or would the tidal forces rip him apart? In other words, are these wormholes basically just black holes that tear you up into individual elementary particles and then spit those particles into another universe?
