Traversable wormholes from broken cosmic strings and vacuum black hole pair prodction

Oh, right.

First, it’s extremely high-quality. Both Gary Horowitz and Don Marolf are famous; I’ve been to conferences and colloquia where they’ve keynoted.

Second, it’s more confirmation that wormholes are actually valid.

Horowitz, Marolf, et. al show, both analytically and numerically, that you can create stable traversable wormholes in our (deSitter) universe without requiring unphysical amounts of negative stress-energy.

This particular paper uses black hole pair production mediated by a broken cosmic string.

That’s actually not exceptionally difficult to do all things considered, as those conditions generally exist shortly after the Big Bang.

In essence, this paper verified our conjecture that Weyl-forges work with microscopic black holes under exotic (early universe) conditions.
