All time exists at once. There is no creation of past or present or future, for they all were created already. It is the focus of consciousness which creates the illusion of time's linearity.
In geometric terms, it is the intersection of n-D forms.
The intersection of 2 unequal 1-D lines in 2-D space is a 0-D point. If one of the lines is rotating with respect to the other, the point of intersection will move from negative infinity to positive infinity in half a rotation. This could span eternity if the line represented time.
The intersection of 2 unequal 2-D planes in 3-D space is a 1-D line orthogonal to the normal vectors of both planes.
The intersection of 2 unequal 3-D volumes in 4-D space is a 2-D plane.
Finally, the intersection of 2 unequal 4-D hypervolumes in 5-D space is a 3-D volume, which can describe the entire universe at a given instant. Thus by rotating one of the 4-D hypervolumes, a continuously-moving universe can be created. However, the entire 4-D expanse of space and time always exists; it is only the focus of consciousness that changes linearly.
