Meaning and Definition
A theoretical, hypothetical one-dimensional topological defect in spacetime, postulated in cosmology and theoretical physics.
An extended, extremely thin and dense object with immense mass, predicted by some models of the early universe, which could have influenced the formation of galaxies. In a loose figurative sense, it can refer to any invisible, connecting line or force of immense scale.

FAQ
Frequently Asked Questions
No, cosmic strings remain a purely theoretical prediction. No conclusive observational evidence for their existence has been found.
Theoretically, they are predicted to be narrower than a proton but can be incredibly long, potentially stretching across the observable universe.
No, they are different concepts. Cosmic strings are macroscopic spacetime defects, while string theory strings are fundamental, subatomic entities.
While purely hypothetical, if one passed through our solar system, its immense gravitational influence could have catastrophic effects, but the probability is considered vanishingly small.
