Theoretically is it possible to propel a vessel through space by creating a wave in space time using intense amounts of light to bend space time?
The problem is creating the expanding part of space-time. It is not possible to do that with ordinary mass-energy (not with light or anything else with positive mass-energy). It is known that to create such a bend in space-time requires mass-energy that violates the averaged null energy condition (Wikipedia- Energy condition). There is nothing that is known to violate this energy condition, but theoretically such things could exist (Arxiv paper on the theoretical violation of said energy condition).nitronewt said:It would seem that if we could create a pulse strong enough to bend space-time in the manner showed by Antiphon's link, it could create a wave in space-time that would propel a ship forward.
Gravitational propulsion is a theoretical method of space travel that utilizes the force of gravity to propel a spacecraft without the need for traditional rocket propulsion systems.
Gravitational propulsion works by utilizing the gravitational pull of celestial bodies, such as planets or stars, to accelerate a spacecraft. This can be achieved through techniques such as slingshot maneuvers or using the gravitational pull of a planet to assist in the spacecraft's acceleration.
The potential benefits of gravitational propulsion include reduced fuel consumption, faster travel times, and the ability to explore deeper into space. It also has the potential to make space travel more cost-effective and sustainable.
Gravitational propulsion is still a theoretical concept and has not yet been implemented in any spacecraft. However, certain aspects of gravitational propulsion, such as slingshot maneuvers, have been used in past space missions to increase speed and conserve fuel.
One of the main challenges of gravitational propulsion is accurately calculating and predicting the gravitational forces of celestial bodies. Other limitations include the need for precise timing and positioning, potential risks to astronauts, and the need for advanced technology and resources to implement this method of propulsion.
