SUMMARY

The discussion centers on the concept of the universe as a membrane with minimal dimensions, specifically addressing the LCDM cosmological model, which asserts that there is no experimental evidence supporting the existence of more than four dimensions. Participants highlight the search for missing momentum in scattering processes at the Large Hadron Collider (LHC) as a potential indicator of extra dimensions, while also noting that such missing momentum could alternatively suggest the presence of undetected particles.

PREREQUISITES
  • Understanding of the LCDM cosmological model
  • Familiarity with particle physics and scattering processes
  • Knowledge of the Large Hadron Collider (LHC) operations
  • Basic concepts of dimensionality in theoretical physics
NEXT STEPS
  • Research the implications of missing momentum in particle physics
  • Study the LCDM model in detail
  • Explore the role of the LHC in searching for extra dimensions
  • Investigate theoretical frameworks for higher-dimensional universes
USEFUL FOR

Physicists, cosmologists, and anyone interested in the fundamental structure of the universe and the implications of dimensionality in modern physics.

is our universe a membrane with almost no dimension(the space between two quarks)?

Not according to the cosmological model that best explains our observations, ie. the LCDM model. There is no experimental evidence of more than 4D.

One thing they are looking for at LHC is missing momentum in scattering processes. Missing momentum could indicate existence of extra dimensions. However, it can also indicate undetected particles.

thanks, that was a good explanation
