No. I don't know of any cosmogony that postulates a massive central point. They generally assume zero mass-energy. >To me there is > something wrong with this idea because there is no reason for > thinking that the strength of gravity now is any more than it > has been in the past, so how come everything managed to escape? > "Does not compute" says I. > > So how about this: There was never any 'singularity' in the > sense of an isolated ball of energy/mass which exploded > 'outwards' to spread itself ever more thinly through the 'empty' > space-time that grew and continues to grow. All current theories suppose that spacetime is expanding - not that a ball of matter expands into a pre-existing spacetime.
