I've been ruminating over an idea that's been floating around in my head for a few weeks. My understanding of theoretical physics is lacking compared to many of the members of this fine establishment, so I'm curious to hear the thoughts of someone more knowledgeable than myself.
In asymptotic safe gravity, you have a non-gaussian fixed point at which the theory becomes conformally invariant.
Also in AS, spacetime at the Planck scale is believed to go from four dimensions down to two (I think this is the way it works, but my understanding of the term dimension as it used in this context may be incorrect- I am not sure if they are referring to geometry or the order of mass terms in the Lagrangian, etc...).
In string theory you have a two dimensional world sheet the equations of motion of which are given by conformal invariance (beta = 0 gives string equations of motion). So wouldn't it be natural to ask if AS gravity is equivalent or dual to a stringy model at the fixed point (but not necessarily elsewhere)?
I look forward to hearing thoughts on this. Thanks.
