Towards Quantum Gravity
Aside from the obvious statement that it should be a theory capable of unifying general relativity and quantum field theory, not much is known about the true nature of quantum gravity. Because it is an exciting area of research, there are many new ideas about quantum gravity, but they often diverge to such an incredible degree that it seems impossible to decide which of the many possible directions the ongoing developments should be pursued.
The aim of this book is to give graduate students an overview of quantum gravity but it also covers related topics from astrophysics. Some well-written contributions can serve as an introduction into basic conceptual concepts like time in quantum gravity or the emergence of a classical world from quantum cosmology. This makes the volume attractive to philosophers of science, too.
