Does anybody have any knowledge on closed timelike curves

Question

can i ask you some questions? there is no email adress.

Answer 1

I answered this once before.  In order to create a closed time-like curve, you would have to be able to travel backward in time.  This would lead to a contradiction in that some point in space-time would lie in its own past.  So a clsoed-time like curve violates causality, and isn't possible.
