So if you're looking for cosmic strings, you look for galaxies that seem to appear twice, and there's no visible cause of lensing.

Morphology
The compound is directly compositional: 'cosmic' (relating to the universe) + 'string' (a thin, thread-like object) yields the idea of a string-like object in space. Although the full scientific implications (energy concentration, one-dimensionality) are technical, the basic referent is literal and predictable from the constituents, so a B1 learner knowing both words would grasp the core meaning.
Etymology
Cosmic string may come from a simple image: a very thin string or 'thread' stretched across space and full of energy, with cosmic meaning 'in space'. That's why the name is used for a tiny, energetic line in the universe.
