JUNAID BASHIR on Instagram: "A space drive is a theoretical propulsion concept in which a spacecraft could accelerate without ejecting propellant, unlike conventional rockets that rely on Newton’s third law. Instead of throwing mass backward, a space drive would generate thrust by interacting directly with the fundamental structure of space-time, inertia, or quantum fields. Several ideas fall under the space-drive umbrella. Some propose manipulating space-time itself, such as warp-drive metrics,
