Mallett’s vision for a time machine centers on what he calls “an intense and continuous rotating beam of light” to manipulate gravity. His device would use a ring of lasers to mimic the spacetime-distorting effects of a black hole.
Can only go back to when you started operating the device. So, basically the Primer time machine, except the math says it has to be done at galactic black hole amounts of energy sort of scale.
The study suggests that some event within the last 350 million years altered its trajectory, preventing it from settling into a circular orbit.
That’s within the current best estimates for the age of Saturn’s ring system… maybe the same catastrophic event that formed the rings is also responsible for the anomaly in Titan’s orbit?
