my first post about space/cosmology theme ... why not ?... the topic of space has been of interest and important to me for a long time , i continue to study it as well as things from the category of archeology .
☀Cosmic String
(For some reason , the choice fell on cosmic string hmmm...) the consequence of the evolution of the universe, one-dimensional topological defect of space-time.
Cosmic strings are theoretical objects in physics that may exist in our Universe. They can be thought of as very thin but long "threads" or "strings" that can be enormous in length but very thin in thickness.
At the moment, cosmic strings are hypothetical objects and their existence has not yet been confirmed experimentally. Scientists are looking for ways to detect them, for example, by observing gravitational waves.
Scientists suggest that cosmic strings may explain some observed phenomena in the Universe, such as gravitational waves or anomalies in the cosmic microwave background...
( source ) ↑ - One of the interesting properties of a cosmic string is that it doesn't take 360 degrees to walk around one; it takes slightly less. This phenomena is called the "deficit angle", and leads to some interesting properties for the gravitational lensing of light by cosmic strings.

based on this source it can be assumed that a cosmic string colliding with the earth is capable of causing a strong earthquake
