Early Universe Cosmology in Internal Relativity
Olaf Dreyer
We present a new approach to early universe cosmology. Inflation is replaced by a phase transition in which both matter and geometry are created simultaneously. We calculate the sp…
Why things fall
Olaf Dreyer
In this paper we discuss Internal Relativity, a recent program to address the problem of quantum gravity. In our approach we change the relationship between spacetime and matter. C…
Relational Physics and Quantum Space
Olaf Dreyer
In a purely relational theory there exists a tension between the relational character of the theory and the existence of quantities like distance and duration. We review this issue…
Isolated Horizons in 2+1 Gravity
Abhay Ashtekar, Olaf Dreyer, Jacek Wisniewski
Using ideas employed in higher dimensional gravity, non-expanding, weakly isolated and isolated horizons are introduced and analyzed in 2+1 dimensions. While the basic definitions…
