Is there a minimum unit of time in string theory?

Click For Summary
SUMMARY

The minimum unit of time in string theory is defined as the Planck time, which is the duration it takes for light to travel a Planck distance. Strings, being of Planck length, cannot exist in smaller spacetime intervals. This implies that any manifestation of matter as a vibrating string requires the definition of a whole string within the constraints of Planck time. Recent discussions indicate that string theory does not inherently create time but exists within the framework of spacetime.

PREREQUISITES
  • Understanding of Planck time and Planck length
  • Basic knowledge of string theory concepts
  • Familiarity with spacetime and its properties
  • Awareness of entropy in the context of finite temperature in string theory
NEXT STEPS
  • Research the implications of Planck time on quantum mechanics
  • Explore the relationship between string vibrations and spacetime
  • Investigate recent studies on string theory at finite temperatures
  • Examine the concept of entropy in string theory frameworks
USEFUL FOR

Physicists, theoretical researchers, and students interested in advanced concepts of string theory and the nature of time in quantum mechanics.

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.
