Open strings in superstring theory can indeed have their ends attached to different branes, which raises questions about potential observable effects in our universe. If a string representing a photon has one end on our brane and the other on a separate brane, it could theoretically influence interactions or observations in our universe. However, the implications of such a configuration are complex and not fully understood, especially for those new to the subject. For beginners seeking to learn more about superstring theory, it is recommended to explore introductory resources that simplify the mathematical concepts involved. Understanding these foundational ideas is crucial for grasping the broader implications of string theory in physics.

Hello, I have only recently begun learning about superstring theory and I have a few queries. one of which is this.

Open string must have ther ends attached to a brane, I think I am right in saying that one end can be attached to one brane while the other to another separate brane. So in the brane world situation where our observable universe exists in a brane which is just one brane of many; imagine an open string (say one that describes a photon) having one end attached to our brane and then other end attached to another. Would this situation lead to something observable?

again i have little understanding of super string theory and virtually no mathemtical understanding of the theory so i don't even know if my question has much meaning.

I would also really appreciate if someone could point me towards some entry level material to learn from.
Thanks

Thread 'Questioning the timescape model'

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
