I've been thinking about vortons--closed loops of cosmic string that are stable because of the angular momentum of trapped particles on them--and I wonder if they might be useful for something.

I did some very rough mass calculation of them. I assumed a vorton with a circumference of about 9.4 femtometers, and that a kilometer of cosmic string has a mass exactly that of Earth. I got 56,284,774.2 kg. Wow. Black holes of the same mass are only a couple of orders of magnitude smaller, but of course they are unstable due to Hawking radiation.

Like black holes, vortons can have a charge, so they can be manipulated.
