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

[Tachyon]

Thanks for the info sounds interesting. I had another look at the paper but again not finding it easy to extract information. Do they give a way to calculate how much energy is required for a wormhole of a given radius? If so how does it stack up to OA?

I’d have to run their simulation software to check. It’s something I’d like to do but I’m rather occupied with my own research at the moment.
