Richard Gott III of Princeton University, this solution involves two cosmic strings
-- a pair of extremely thin, invisible strands of concentrated energy that warp space-time in a peculiar way.
Gripped,I watched on -through an increasingly complex discussion of cosmic strings
, space- time continuums and loops in the universe -all entertainingly presented,all explained in simple terms,but all utterly impenetrable.
This could be an optical illusion--or perhaps the result of some physical phenomenon such as spherical shock waves colliding or cosmic strings
He has done research work on models of the very early universe studying inflationary cosmology and cosmic strings
Many theories predict the existence of cosmic strings
The theoretical field is thick with candidates such as magnetic monopoles--particles with a single north or south pole--and endless wires of tightly bunched energy called cosmic strings
(SN: 12/7/96, p.
Proposals on a growing list range from decaying superheavy particles in this galaxy to colliding cosmic strings
of energy stretching across all of space.
are investigating another type of model, one in which the missing energy would come from a tangle of lightweight cosmic strings
distributed throughout the universe.
Our results point to several experimental and theoretical situations where such structures may be relevant, ranging from defects in liquid crystals and vortices in superfluid helium to the structure-forming role of cosmic strings
in the early universe," Niemi and Faddeev say.
These results suggest that cosmic strings
preserved remnants of primordial matter, seething at the high temperature of the Big Bang, long after the birth of the universe.
Hence, the principle of mediocrity favors scenarios in which cosmic strings
or other spacetime defects (SN: 10/15/94, p.
Noting the similarity between the mathematical model used by Kibble for the formation of cosmic strings
and models used in condensedmatter physics to describe certain kinds of phase transitions, researchers have in recent years turned to laboratory experiments to test the credibility of Kibble's structure-forming mechanism.
That theory holds that variations in the microwave background are the same in all parts of the sky Other theories, which require the presence in the early universe of unusual structures, called cosmic strings
or textures, predict just the opposite.
