This is interesting and if the experimental evidence confirms this hypothesis, it bodes well for our future. A universe where we can interact with spacetime via engineering is one that allows for a lot of creative freedom. They also have another interesting article claiming that the imaginary structure of QM is the result of stochastic optimization on spacetimes: https://www.nature.com/articles/s41598-019-56357-3

Maybe the UAPs really are just secret warp drive tech we made 20 or 30 years ago.
