Auckland, New Zealand: COSPA 2014: 10th International Symposium on Cosmology and Particle Astrophysics, 8-12 Dec 2014.http://hdl.handle.net/10092/10177Apparent cosmic acceleration can be understood by treating geometry of universe more realistically understanding fundamental aspects of general relativity which have not been fully explored – quasi–local gravitational energy, of gradients in kinetic energy of expansion etc. “Timescape” model gives good fit to major independent tests of CDM with new perspectives on many puzzles – e.g., ‘local’/global differences in H0; primordial 7Li ? Many tests can be done to distinguish from CDM. Must be careful not to assume Friedmann equation in any data reduction. “Modified Geometry” rather than “Modified Gravity”enConference Contributions - OtherFields of Research::51 - Physical sciences::5101 - Astronomical sciences::510103 - Cosmology and extragalactic astronomy
