By using two microsingularites in close proximity to each other, it is possible to create, manipulate and alter the Kerr fields to create a Tipler gravity sinusoid. This field can be adjusted, rotated and moved in order to simulate the movement of mass through a donut-shaped singularity and into an alternate world line. Thus, safe time travel.

ACCELERATION = TIME DILATION
As pointed out earlier, acceleration will produce time dilation. This can be observed by the “twins paradox”. As one twin stays on Earth, the other twin in his accelerating spaceship experiences a slower passing of time.
