Is the concept still current, of our three dimensional Universe being finite because it is curved in all directions but in four dimensional space, each of those curvatures being complete (a closed loop) which results in there being no edge to it?

...

So, if this hypothesis were to be correct there could be a pressure (or whatever it may be called in four dimensional space) which is greater on the inside of the closed curvature than outside. This could be the dark matter/energy which is responsible for the greater than expected expansion rate of the Universe. Does anyone know if this idea has been considered by other than me?
