I have studied the concept of light cones, which Albert Einstein drew inspiration from and integrated into his theory of relativity. Building on this foundation, I propose that gravitational lenses could fold a light cone back onto itself. In my conceptual diagram, I positioned gravitational lenses on both sides of Earth, allowing the past and future light cones to fold inward. While this does not enable time travel, if my hypothesis is correct, it would cause the past, present, and future to overlap at a single point—potentially allowing the past or future to be altered.  

In my illustration, if point *E* emits matter particles, it triggers events in the future light cone. Conversely, if matter particles are directed toward *E*, they could influence events in the past light cone. If my theory holds, emitting particles toward *E* might enable corrections to the past.  

I have also attached my earlier draft on time, which I once submitted to the Royal Society. It was rejected for lacking scientific rigor and failing to reference prior work by earlier scientists (a criticism I agree with). Nonetheless, I included it here because I remain fond of one idea from it: *"We do not yet understand time well enough."*  

However, if this concept were to be experimentally tested, I might need to collaborate with NASA or relevant government agencies. To be honest, I do not fully trust government institutions, and I am uncertain whether NASA or any government body would even assist in conducting such an experiment.
