Physical Interpretation of Compactified Dimensions?

Click For Summary
SUMMARY

String theory's compactified dimensions are theorized to represent the local permissible evolution space for strings, which vibrate in 10 dimensions, while M Theory expands this to 11 dimensions. These additional dimensions may be compact and so minuscule, on the order of the Planck length, that they are imperceptible to light and gamma rays. High-frequency gravity waves may penetrate these dimensions, potentially leading to interactions with the multiverse through black holes. Although the theory remains largely untestable, it is anticipated that M Theory and quantum gravity will receive significant attention in the pursuit of a Theory of Everything.

PREREQUISITES
  • Understanding of string theory fundamentals
  • Familiarity with M Theory and its implications
  • Knowledge of Planck length and its significance in physics
  • Basic concepts of black holes and multiverse theories
NEXT STEPS
  • Research the implications of M Theory on our understanding of dimensions
  • Study the role of gravity waves in theoretical physics
  • Explore the concept of the multiverse and its relation to string theory
  • Investigate current advancements in quantum gravity research
USEFUL FOR

Physicists, theoretical researchers, and students interested in advanced concepts of string theory, M Theory, and the quest for a unified theory in physics.

Do string theory’s compactified dimensions have a predicted physical interpretation? Do they for example represent the space/planes/domains in which a string ‘lives’? That is, the local permissible evolution space of a given string?IH

One dimension open or closed strings vibrate in 10 dimensions, at least mathematically. The later M Theory had 11 dimensions. Outside of our visual 3 space dimensions and one time dimensions may lie the other 6 or 7 compact dimensions that if they exist, they maybe so small , Planck length order of magnitude, that nothing, nor even light and gamma rays, can penetrate them. Nothing, that is , except possible high frequency gravity waves with wave lengths so small that makes them possible to enter them and beyond to the postulated multiverse (other Branes) by way of black holes. This is all postulated, the Theory may not be falsifiable, but much attention will be focused on M theory and quantum gravity in the decades ahead, as the search continues for a Theory of Everything to unlock the universes darkest secrets. Maybe. And that's about all I know from the readings.
