String Theory and General RelativityWe give a historical review of some aspects of string theory relevant to our present understanding of General Relativity and connected with Einstein's unification program.doi:10.1007/978-88-470-2113-6_3M. PorratiSpringer Milan...
The low energy effective Lagrangian of string theory presents us with not only gravity, but the dilaton and the antisymmetric field as well. It is shown that a Brans-Dicke generalization of a metric theory of gravity with torsion that is derived as the exterior derivative of a potential is ...
Thus, we can say that there is some empirical evidence for string Theory - it predicts the graviton (as well as the photon)! General Relativity describes gravity, but it is not a quantum mechanical theory and so is expected to break down at very small scales (like the Planck length) and...
String theory has been held up as a possible "theory of everything," a single framework that could unitegeneral relativityandquantum mechanics, two theories that underlie almost all of modern physics. While quantum mechanics does very well in describing the behavior of very small things and genera...
This is because string theory allows for the consistent combination of quantum field theory and general relativity, agrees with general insights in quantum gravity such as the holographic principle and black hole thermodynamics, and because it has passed many non-trivial checks of its internal ...

Collective Coordinates in String TheoryGeneral Relativity and Quantum CosmologyHigh Energy Physics - TheoryA string theory in $3$ euclidean spacetime dimensions is found to describe the semiclassical behavior of a certain exact physical state of quantum general relativity in $4$ dimensions. Both the ...
The time difference amounts to hours, thus being measurable and permiting to distinguish between General Relativity and String Theory charged black holes.Alexis LarranagaPhysicsLarran˜aga Rubio, E.A., "Time delay in gravitational lensing by a charged black hole of string theory", arXiv e-...
A detailed discussion of the evaluation of tree-approximation scattering amplitudes is also given. Featuring a new Preface setting the work in context in light of recent advances, this book is invaluable for graduate students and researchers in general relativity and elementary particle theory....
String theory has provided a resolution of the puzzles that arise in the quantum theory of black holes. The emerging picture of the hole, encoded in the &#
