My question is
Let's say you have an object moving through space locally at less than the speed of light. Is it possible to watch that object playing backwards like a record spinning the wrong direction according to the following version of general relativity? One where space doesn't exist in spots that would take an infinite amount of time to compute how it goes directly from causation in the direction of the future light cone such as where there would be closed time like curves. That is, could you watch an object playing backwards from something like light from that object bending around a fast moving black hole then bending around another fast moving black hole before it reaches you.
If the answer is yes, then that probably means it's also possible to produce something like the sonic boom but with light. I know that a an object travelling in a time contraction track fast enough while still being below the speed of light within the track could produce a luminous boom. So a really distant object that normally would be extremely dim could have a flash of appearing much brighter than usual. Having 2 images of a galaxy behind another galaxy from gravitational lensing doesn't count. I know that if you look at the one from more recently then the one from longer ago, you are observing one event first then another event that's in its past light cone. However, in each image, you are watching it playing forwards.
