one universe with a *beginning to time of which there was no before.
The future is infinite. The future of the hypersphere is Infinity.

Mitch,
we don"t need 4D and hypersphere. Euclidean 3D is quite good enough
and confirmed.

But who knows ...may be you are right, but :
- hypersphere needs 4D,
- hypersphere is 3D volume, 2D surface in 4D,

And what about time ?
4D + time ?
Any experiments ?
