SUMMARY

The discussion centers on the concept of discrete space and its relationship to the Planck length, specifically questioning whether distances beyond the Planck length, such as those near proton width, have been proposed or studied. Participants reference the implications of discrete space-time, where energy and momentum conservation occurs modulo the inverse lattice spacing. The conversation highlights the theoretical framework established by physicist Leonard Susskind regarding the energy desert between TeV and 1019 GeV, emphasizing the need for further exploration of lengths beyond the Planck scale.

PREREQUISITES
  • Understanding of discrete space-time concepts
  • Familiarity with Planck length and its significance in physics
  • Knowledge of energy conservation principles in quantum mechanics
  • Awareness of high-energy physics, particularly the energy scales mentioned by Leonard Susskind
NEXT STEPS
  • Research the implications of discrete space-time on quantum field theories
  • Explore theoretical frameworks that propose distances beyond the Planck length
  • Study Leonard Susskind's theories on the energy desert between TeV and 1019 GeV
  • Investigate experimental approaches to measuring distances at sub-Planck scales
USEFUL FOR

Theoretical physicists, researchers in quantum mechanics, and anyone interested in the implications of discrete space-time on fundamental physics.

Discrete space has been proposed at Planck length. But has any other distance been proposed(studied), like near proton width.

Discrete space time means that energy and momentum are only conserved modulo the inverse lattice spacing.

Yes, but my question was about if anybody tried or thought that the Planck length might not be the only length possible. Since, as Susskind puts it the desert from TeV to 10^19 GeV. Of course, I know the rarional for Planck length case.
