Cosmic strings are one-dimensional topological defects that exist in the fabric of space, characterized by having length but no width or height. They are not directly related to other dimensions or gravitons, although they can manifest as mass and thus act as a source of gravitation. The discussion references a wiki article and a research paper that explore the theoretical aspects of cosmic strings and their potential real-world detection. While the interpretation of cosmic strings is based on existing literature, the accuracy of these interpretations is not guaranteed. The conversation highlights interest in further understanding and locating cosmic strings in practical terms.
