Cosmic strings are hypothetical 1-dimensional topological defects which may have formed during a symmetry-breaking phase transition in the early universe when the topology of the vacuum manifold associated to this symmetry breaking was not simply connected.

In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other.

A strange pair of galaxies several billion light-years away could be evidence of a hypothetical 'crease' in the Universe's fabric known as a cosmic string.

Jan 8, 2010 · Cosmic strings are analogous objects that may have been formed in the early universe. They could be produced during one of the early symmetry-breaking phase transitions predicted by many particle-physics models, for example one associated with the breaking of a ‘grand unification’ symmetry.

Dec 9, 2021 · A cosmic string is, put simply, a flaw. A crack. A defect. A fold in the very fabric of spacetime itself. If they exist, they were made in the earliest moments of the big bang, when the insane energies were capable of twisting and distorting spacetime so …

Mar 8, 2023 · Abstract: We review applications of string theory to cosmology, from primordial times to the present-day accelerated expansion. Starting with a brief overview of cosmology and string compactifications, we discuss in detail moduli stabilisation, inflation in string theory, the impact of string theory on post-inflationary dynamics (reheating ...

Jan 1, 2025 · Cosmic strings were first theorized in the mid-1970s as a possible outcome of symmetry-breaking processes in the early universe. The concept emerged from the work of theoretical physicists Tom W. B. Kibble and others exploring the implications of grand unified theories (GUTs) for cosmology.

Jul 15, 2024 · Cosmic string theory represents a captivating intersection of theoretical physics and cosmology, offering profound insights into the early universe and the fundamental forces that govern it.

Feb 5, 2025 · One exciting area of study involves String Theory, which suggests that everything in the universe is made up of tiny, vibrating strings. This theory aims to address some of the unanswered questions in physics, like why gravity is so weak compared to other forces.
