Cosmological Time in (2+1)-Gravity
We consider maximal globally hyperbolic flat (2+1) spacetimes with compact space S of genus g > 1. For any spacetime M of this type, the length of time that the events have been in existence is M defines a global time, called the cosmological time CT of M , which reveals deep intrinsic properties of spacetime. In particular, the past/future asymptotic states of the cosmological time recover and...

Rapid advances in observational cosmology have led to the establishment of a precision cosmological model, with many of the key cosmological parameters determined to one or two significant figure accuracy. Particularly prominent are measurements of cosmic microwave background (CMB) anisotropies, led by the seven-year results from the Wilkinson Microwave Anisotropy Probe (WMAP) [1–3]. However th...
متن کاملCosmological measurements, time and observables in (2+1)-dimensional gravity
We investigate the relation between measurements and the physical observables for vacuum spacetimes with compact spatial surfaces in (2+1)-gravity with vanishing cosmological constant. By considering an observer who emits lightrays that return to him at a later time, we obtain explicit expressions for several measurable quantities as functions on the physical phase space of the theory: the eige...

The canonical Cosmological Time Function (CTF) is a tame global time function on matter-free maximal globally hyperbolic (2+1) spacetimes with compact space of genus g. In particular, when g ≥ 2, (CFT) is a solution of a relaxed constant mean curvature evolution problem; the connected components of a dense open set in each level surface Sa have both intrinsic and extrinsic constant curvature; e...
متن کاملQuantum gravity and cosmological observations
Quantum gravity places entirely new challenges on the formulation of a consistent theory as well as on an extraction of potentially observable effects. Quantum corrections due to the gravitational field are commonly expected to be tiny because of the smallness of the Planck length. However, a consistent formulation now shows that key features of quantum gravity imply magnification effects on co...
