What is the nature of dimensionality in 11 dimension M-theory?

SUMMARY

The discussion centers on the nature of dimensionality in 11-dimensional M-theory, emphasizing the existence of metric equations for dimensions and the cyclic flow of energy between them. Participants reference "Gravity" by James Hartle as a key resource for understanding metric tensors in compactified dimensions. The conversation highlights the need for foundational knowledge in quantum field theory (QFT) and string theories to engage meaningfully with M-theory topics. The thread concludes with a recommendation to explore simpler examples, such as the Riemann sphere, for questions about topology and compactifications.

PREREQUISITES
  • Understanding of metric tensors in general relativity
  • Familiarity with quantum field theory (QFT)
  • Knowledge of string theory concepts
  • Basic comprehension of topology, particularly compactifications
NEXT STEPS
  • Study "Gravity" by James Hartle for insights on metric tensors
  • Learn about quantum field theory (QFT) fundamentals
  • Explore string theory principles and their implications
  • Research the topology of the Riemann sphere and its applications
USEFUL FOR

Physicists, theoretical researchers, and advanced students interested in M-theory, quantum field theory, and the mathematical foundations of string theory.

TL;DR
What are the signatures and distance metrics for the compactified dimensions?
They're dimensions, so they DO have a metric equation, right? Does energy flow cyclically between pairs of dimensions? To me, that's what rotation is.

Are you trying to learn here? There's a pretty decent explanation in "Gravity" by James Hartle (the only undergraduate-level general relativity textbook I known of) including an example of a metric tensor for a manifold with a compactified dimension.

Or are you trying to see how many times we'll let you violate the forum rule about personal speculation?
 
If you want to discuss M-theory, @Paige_Turner, then it is best to do it in the "Beyond the Standard Model" forum. However, it is an extremely technical subject, that cannot be dealt with on a "B" level thread. You will need to learn QFT and string theories first, and there is no shortcut.

It is something else to ask about the topology of compactifications. For questions about them, I recommend choosing some easier examples like the Riemann sphere.

The question as stated is unanswerable, so I close this thread.
