Exploring Cosmic Strings: Dimensions & Gravitons

[SpaceDreamer]

I have reading about cosmic strings and have some questions about them, are they in any way related to other dimensions even though they are one dimensional? Also do they have anything to do with gravitons and the cause of gravity?

No, they are simply topological defects that have only 1 dimension. By dimension we mean the mathematical dimensions, like the XYZ axis on a graph. A cosmic string would be a defect running in 1 dimension, so it would have length but no width or height. (The wiki article says it would have a diameter of about 1 femtometer, which is about the diameter of a proton, so it may or may not be actually 1 dimensional, but for all intents and purposes it can be considered 1d)

They are not related to gravitation, although they would manifest as mass, and would therefore be a source of gravitation like all mass and energy are.

But all that is my interpretation of what the wiki article says, so I can't guarantee that it is accurate.

The paper was helpful and interesting so thank you, I saw as I was reading it, it might be possible to locate the strings theoretically in the real world. Besides what is in the paper would any of you guys know how this could be done.

Thank you for your interest in cosmic strings and their potential connections to other dimensions and gravitons. Cosmic strings are hypothetical one-dimensional objects that are thought to have formed in the early universe during a phase transition. They are believed to have a high energy density and can potentially stretch across vast distances in space.

In terms of their relation to other dimensions, it is currently unknown if cosmic strings have any connection to higher dimensions beyond the three spatial dimensions we are familiar with. Some theories suggest that cosmic strings may exist in a higher-dimensional space, but this is still a topic of ongoing research and debate.

As for their connection to gravitons and the cause of gravity, cosmic strings have been proposed as a possible source of gravitational waves, which are ripples in the fabric of space-time. Gravitons, on the other hand, are theoretical particles that are believed to be the carriers of the gravitational force. While there is currently no direct evidence linking cosmic strings to gravitons, some theories suggest that the interactions between cosmic strings and other particles could potentially produce gravitons.

Overall, the study of cosmic strings is a fascinating and complex area of research that continues to be explored by scientists. While their relation to other dimensions and gravitons is still not fully understood, further studies and experiments may provide more insights into these intriguing objects and their potential role in the universe.
