Theoretical physicist from Vienna, Austria. My focus is the theory of strong interactions and its study via the AdS/CFT correspondence, but I am also interested in aspects of general relativity, particle physics and string theory not related to holography.

comment AdS/CFT dual of $N$ D$p$-branes at finite temperature
Your statement is not true, AdS is not restricted to $p=3$.

comment Why & What extra dimensions in M-theory?
@CuriousOne: While it is possible that this is true, I don't see how this contributes anything to an answer to this question, which is not about the "correctness" of string theory, but about its basic principles.

@BlessedGeek: I suggest that you look up and try to understand the meaning of dimension in the context of physics, this will definitely help you find an answer to your question.

comment Philosophy enquiry of string theory
@innisfree: The development of scientific theories is motivated both by experimental input and conceptual issues. Since experimental evidence for string theory might lie beyond our current technological capabilities (keyword: Planck scale), conceptual questions naturally play a bigger role (think quantum gravity, grand unification). While I acknowledge that people do raise those questions in the context of string theory, their justification is questionable. These issues are hyped especially on the level of popular science, but there is little actual scientific value to them.

comment Philosophy enquiry of string theory
@innisfree: "ST is not a theory like any other; it challenges our ideas about science." May I ask how you come to this conclusion? The only real difference between string theory and GR or QFT is that it contains much more than these two frameworks, and that it allows one to address deeper questions, which is due to its more fundamental nature. How does this challenge anything we know about science?

comment String frame and Einstein frame for a Dp-brane
Would you be so kind and tell me what the source of your expressions is? The answer might depend on the definition of $\phi$.

comment Energy not conserved with accleration by a constant force
@Brilliand: If you supply external energy, the energy os the original system is definitely not conserved, but increased (as you have correctly pointed out through your formula).
