What is a Reactionless engine?
Table of Contents
By definition, a reactionless drive or inertia propulsion engine is any form of propulsion not based around the expulsion of fuel or reaction mass. The name “reaction mass” comes from Newton’s Third Law of Motion, usually expressed as, “For every action, there is an equal and opposite reaction.”
Is reactionless drive possible?
Physicist: In a word: no. A reactionless drive is basically a closed box with the ability to just start moving, on its own, without touching or exuding anything.
Can you move in space without propellant?

A NASA study has recently concluded that the “Cannae Drive,” a disruptive new method of space propulsion, can produce small amounts of thrust without the use of propellant, in apparent discordance with Newton’s third law.
What is curvature propulsion?
And that is the reason why the “curvature propulsion engine” is not limited by the speed of light or the difficulties of propelling any object larger than a (mass-less) photon to the speed of light– the “curvature propulsion engine” is NOT moving or being propelled itself, but “moving or propelling” the SPACE AROUND …

Is electromagnetic propulsion possible?
This week, the team formally published their experimental evidence for an electromagnetic propulsion system that could power a spacecraft through the void—without using any kind of propellant.
Can electricity be used for propulsion?
Electric Propulsion (EP) is a class of space propulsion which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means. The use of electrical power enhances the propulsive performances of the EP thrusters compared with conventional chemical thrusters.
What is warp theory?
Alcubierre’s warp drive would work by creating a bubble of flat spacetime around the spaceship and curving spacetime around that bubble to reduce distances. The warp drive would require either negative mass – a theorized type of matter – or a ring of negative energy density to work.
