I have read papers regarding mechanisms responsible for maintaining the compactness of the extra dimensions and also read papers regarding how the 3 large dimensions became large.
Mechanisms include:
1) Casimir Energy
2) Strings winding around the compact toroidal directions.
Could someone PLEASE explain what the mechanism is that the matter/energy actually COUPLES to spacetime.
Is it merely a general relativistic effect (like a contracting spacetime) or is it deeper.
I have wandered this for a LONG time and never really received a good answer that I can say I truly understand.
Thanks in advance.
