Lemme try again.
No astrophysicist has said there are UNDOUBTABLY eleven dimensions, and certainly not in this thread; what your guy said was, etc etc.
close enough. i'm honestly not so up on my astrophysics.

Has any astrophysicist said "UNDOUBTABLY" anything? They're professional guessers, aren't they?

Astrophysics and theoretical physics are getting mixed up.

Quote:
Astrophysics is the branch of astronomy that deals with the physics of the universe, including the physical properties (luminosity, density, temperature, and chemical composition) of celestial objects such as galaxies, stars, planets, exoplanets, and the interstellar medium, as well as their interactions.

Quote:
Theoretical physics employs mathematical models and abstractions of physics in an attempt to explain experimental data taken of the natural world. Its central core is mathematical physics 1, though other conceptual techniques are also used. The goal is to rationalize, explain and predict physical phenomena. The advancement of science depends in general on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigor while giving little weight to experiments and observations. For example, while developing special relativity, Albert Einstein was concerned with the Lorentz transformation which left Maxwell's equations invariant, but was apparently uninterested in the Michelson-Morley experiment on Earth's drift through a luminiferous ether. On the other hand, Einstein was awarded the Nobel Prize for explaining the photoelectric effect, previously an experimental result lacking a theoretical formulation.

I would say astrophysicists have more of a sense of legitimacy since they are using indirect evidence while theoretical physics use other mediums such as mathematics and have no physical evidence, direct or indirect. Saying that, M-theory is mathematically proven but that really doesn't mean shit.
