The Internal Time Formalism in Canonical Gravityization of the theory both general covariance and the conventional apparatus of quantum field theory. The idea is to extract dynamical variables representing many-fingered time from the phase space of general relativity and then use them as one uses such variables in the quantization of parametrized

Numerical Relativityto astrophysics. While this research field is not new, there are many reasons to believe that it is achieving a certain maturity that will make it useful to the larger relativity and astrophysics communities. I review a number of new developments in numerical relativity, including new collaborations

Integral Constraints in Cosmologyl implications. Traschen’s integral constraint vectors have a particularly simple relation to the Killing vectors of de Sitter spaces. Integral constraints, of which Traschen’s are a special class, exist on any hypersurface with any vector field and on any background..Integral constraints for non-li

Markus Beckmann,Stefan Schalteggerlaxy distribution. There is evidence the luminous central parts of the giant galaxies were present at redshift . = 3. In the cold dark matter model for structure formation the galaxies would have to have been assembled not much earlier than this, in pronounced collapses that may be observable. The g

Messung der ökonomischen Nachhaltigkeitave shown that active star formation in galaxies has continued over the same redshift interval over which active galaxies display strong cosmological evolution. At redshifts greater than 2, there is evidence that many galaxies underwent bursts of continued star formation and that, at the largest red
