    Is this the sort of negative mass that would possibly allow for stable wormholes and therefore time travel?

      I’d recommend Stephen Baxter’s “Ring” novel as a primer on cosmic strings, domain walls (the shell-like mass described here) and using wormholes for time travel.

      Basically covers all of the funky science described in this article

        It’s also really well written. You’ll have to read the rest of the Xeelee sequence afterwards though
