Concentric Tori and Free Fall into the Past

[Travis Tremlee]

What are the similarities and differences with this time machine in the arxiv link and John Titor's descriptions of his time machine with its Tipler sinusoid?

The most remarkable feature emerging from this computation is the presence of future-oriented timelike geodesics starting from a point in the outer Minkowskian region, moving to the inner spacetime region with CTCs, and then returning to the initial spatial position at an earlier time; this means that time travel to the past can be performed by free fall across our time machine.

A time machine is an isolation machine due to it being surrounded by an event horizon. Therefore Schrodinger's cat is not in a box but behind an event horizon isolated from the outside world...

 


A Kerr black hole seems to be similar to a torus with its ring singularity...

Yep, you actually need two to create a "tunnel".
