Gravitational wave propulsion

Gravitational wave propulsion is a theoretical concept that utilizes controlled gravitational waves—Ripples in spacetime caused by massive, accelerating objects—to generate thrust. By creating or manipulating these waves, a spacecraft could potentially push or pull itself through space without traditional fuel, exploiting the fabric of spacetime itself. While still speculative and beyond current technology, this idea hinges on advanced understanding of gravity and spacetime, aiming to enable efficient, long-distance travel by harnessing the natural phenomena predicted by Einstein's theory of general relativity.
