Gott noted that two straight, parallel, infinitely long cosmic strings hurtling past each other in opposite directions could provide a suitable setting for time travel.
The first cosmic strings were unstable and split into small pieces capped by monopoles.
Theory forbids cosmic strings from having ends, so they must appear as loops or infinite strands.
Cosmologists have postulated the existence of cosmic strings to account for the pattern of galaxies in the universe (SN: 12/7/96, p.
You obviously want to push it further-to know not just how many vortices or cosmic strings there were, but also if they are all in loops or long, straight strings.
These experiments showed that a phase transition could generate linelike defects analogous to the cosmic strings of the Kibble mechanism.
Cosmologists have suggested more exotic models -- involving cosmic strings, for example -- that both fit with the new findings and seem to explain the lumpy cosmos.
From this abstract mathematical stew, they extract a mess of exotic geometric structures -- cosmic strings, monopoles, domain walls, global texture -- that rumple the smooth distribution of matter and energy in the universe.
In the past, many of these possibilities -- cosmic strings, global textures, late-time phase transitions -- would have appeared too strange for anyone to take seriously.
It's a way of keeping speculation about dark matter from falling entirely into the hands of particle physicists, who have proposed an array of strange candidates, from weakly interacting massive particles to cosmic strings (SN: 3/4/89, p.
Even physicists often need help in teasing out what such equations mean -- what predictions they make about the behavior of electrons, galaxies or cosmic strings.
