So, rather than being riemannian, spacetime is lobatchevskeyan, and is represented not by the sphere, but by the hyperbola? One question; since the Big Bang was an instantaneous event, yet gravity continues to exert its influence over 'billions and billions' of years, even unto eternity if a Big Crunch is not achieved, how can it be that a finite explosion, however large, will not eventually be drawn 'back to ground' by a pull that can exercise itself for an infinite duration? Wouldn't it HAVE to be achieved eventually, just because of the power of (potentially) forever over even a vast finitude?
