With due respect to prevailing mainstream cosmology, some points are still nagging in my mind... 1. It is stated that Dark Matter does not interact with light, but Dark matter has Gravitational impact. So does it not put a big blow to the Unification Efforts? I mean does it not imply that Electromagnetism has got nothing to do with Gravity (from the Dark Matter point of view only). 2. It is stated that from t = 0 to t= 10^-43 sec remains unexplained and may be QGT would throw some light on this. But inflation supposed to have happened at the accelerated pace from t = 10^-35 to t = 10^-32 seconds and at the end of this inflation the size of universe was still very small (some cricket ball or Football size) having the entire mass. The question is what about Chandra limit and all? The estimated mass of the universe is around 10^53 Kgs, could it have remained compressed in such a small space? 3. About CMBR: I abide by the present explanation of this. But the question is.. Our Universe is Homogeneous and Isotropic, so whatever remote radiation we get around us has to be same? This alone can answer the uniform radiation signal around us (of course it cannot answer the nature of spectrum). But the point is, the relics of a cricket ball size universe is prevalent and present even after 14b years? If this is so then we should have observational evidence of such radiation around any celestial object, ditto around every object. 4. This is just the freaky curious question, is there any concept of ageing of light? Why I am asking this is, that we do not have much issues with the local group Galaxy red shifts (they are Gravity bound) but we get substantial Red Shift (Hubble Expansion) for Galaxies which are very far away, kind of aged light.
