comment If D-branes are the same as p-branes, and p-branes open out to “another universe”, why is the other universe invisible in D-branes?
But don't perturbed D-branes radiate away closed strings to return to a BPS D-brane configuration?

revised Do open strings with both ends attached to the same D-brane really exist?
huge mistake

Are you implying we have complementarity a la Niels Bohr between D-branes and p-branes?

comment At what scale does UV/IR mixing happen in string theory?
If UV/IR mixing happens at the string scale, what happens if we have S-duality between two different string theories? e.g. type IIB, or type I with heterotic SO(32)? There are now two different string scales. Surely UV/IR mixings can't happen at both scales simultaneously? The only scale invariant under S-duality is the Planck scale.

Can you elaborate upon the less understood aspects of UV/IR mixing at the Planck scale? Thanks.
