Is there a minimum unit of time in string theory?

Click For Summary
The discussion centers on the relationship between strings and time in string theory, questioning whether strings create time or vice versa. It is established that strings exist within spacetime and do not generate time themselves. The concept of decay rates for string vibrations is raised, but there is uncertainty about this aspect, particularly regarding finite temperature effects and entropy. The minimum unit of time is identified as the Planck time, which correlates with the size of strings, indicating that strings cannot exist in smaller units of time or space. Overall, the conversation highlights the complexities of defining time within the framework of string theory.

do string make time or does time make strings , since strings have varoius vibrations, do there have a decay rate? just a question maybe one of you might know an answer?

strings do not make time in ordinary string theory. They exist in spacetime and participate in the time from that. I don't know about decaying vibrations in strings. In fact I think it's only recently that anyone has worked on strings at a finite temperature, where you might discuss entropy. This is all just a rumor to me, perhaps someone more learned will chip in.
 
I think it depends on if time is relative. Does time require measurement or does it exist outside of that measurement?

Has anyone thought to define time in terms of string theory? Or is it taken for granted and still measured as it is?
 
time in string theory

Just posted a thread of defining time in string theory. The title is "minimum time" and its found in this (Strings, Branes and LQG) forum. In gist, the smallest unit of time is the Planck time (defined as the amount of time it takes light to travel a Planck distance). Since a string is a Planck length in size, it cannot fit into a smaller space. Therefore, when a photon travels through a Planck distance, it takes up the whole space and can only be defined as a whole string within that amount of time, no less. In other words, if all matter is manifested as a vibrating string, it cannot exist without defining a whole string.
 

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...
