The propellantless propulsion drive system of Exodus Propulsion Technologies, according to its co-founder and ANASA engineer, has produced enough thrust to overcome Earth’s gravitational pull.
This finding, which seems to go against accepted physics, has the potential to transform space travel over the next thousand years.
A veteran of prominent NASA initiatives like the Space Shuttle, the International Space Station (ISS), the Hubble Telescope, and the ongoing NASA Dust Program, Dr. Charles Buhler thinks that this fundamentally new force is a historical discovery.

A Propulsion device that defies physics
EmDrive and the pursuit of propulsion without fuel
British electrical engineer Roger Shawyer first proposed the idea of a propellantless drive, popularly referred to as the “impossible drive,” in 2001.
The so-called EmDrive asserted that it was reactionless, did not need fuel, and broke recognized physics laws, particularly the conservation of momentum. In 2021, after twenty years of testing, the EmDrive was finally declared useless.
Still, the idea of a propellantless machine lingered, and now a new rival with the support of a former NASA scientist has surfaced.
How the EmDrive is said to operate
Microwaves are contained within a conical chamber that makes up the EmDrive. Roger Shawyer, a British engineer who invented the device, suggests that a differential in radiation pressure caused by the microwaves bouncing inside the hollow could provide a net thrust towards the narrow end of the cone.
This idea indicates that propulsion can be generated in a closed system without the need for an external reaction mass, which defies our understanding of physics.
Skepticism and controversy
The touted capabilities of the EmDrive continue to be met with great skepticism by the scientific community. Numerous scientists contend that the idea defies the accepted principles of physics, most notably the conservation of momentum.
They contend that experimental mistakes like air currents or thermal effects are probably to blame for any apparent thrust detected in EmDrive tests.
Trial outcomes and difficulties
The claimed thrust of the EmDrive has been replicated by a number of research teams, with varying degrees of success. A group from NASA’s Eagleworks lab reported to have measured a slight but steady push from an EmDrive device in 2016. Their findings, meanwhile, were criticized for possible methodological errors and were not subjected to peer review.
Independent research conducted later on have not been able to replicate the stated thrust. After a thorough investigation of the EmDrive in 2021, a team from Dresden University of Technology discovered no indications of any unusual thrust.
They came to the conclusion that there is no detectable net propulsion produced by the device and blamed noise and experimental faults for earlier favorable results.
Critical analyzes and theoretical justifications
Theoretical explanations for the EmDrive’s purported thrust have been put forth by its proponents, who frequently bring up ideas like quantum vacuum fluctuations or the pilot-wave interpretation of quantum mechanics.
But because these ideas lack solid mathematical formulation and experimental confirmation, the mainstream scientific community has viewed them with mistrust.
Critics contend that any attempts to use fringe ideas to explain the workings of the EmDrive concept are erroneous and that the notion itself is fundamentally defective. They stress that such extreme assertions require extraordinary evidence, which has not materialized.
The present state and potential of the EmDrive
Research on the EmDrive is still ongoing despite the dearth of strong proof and the scientific community’s general skepticism.
In the hopes of discovering new physics or confirming the stated thrust, a few ardent supporters and fringe scientists are still devoting their time to further research on the idea.
However, the EmDrive’s chances of being used in real life seem dim given the growing body of evidence opposing it and the lack of a solid theoretical basis.
Physicists generally agree that the EmDrive is not a true propulsion breakthrough, but rather an experimental artifact.
Finding of a “New Force”
Before concentrating on electrostatics, Buhler’s team—which included members from the Air Force, Blue Origin, and NASA—investigated propellantless engines for many years.
With each iteration, their devices produced more push than they had at first. Their “New Force” drive produced enough thrust in 2023 to defy gravity on Earth.
“Essentially, what we’ve discovered is that systems that contain an asymmetry in either electrostatic pressure or some kind of electrostatic divergent field can give a system of a center of mass a non-zero force component,” Buhler told The Debrief. “So, what that basically means is that there’s some underlying physics that can essentially place force on an object should those two constraints be met.”
Wary optimism and the requirement for confirmation
Although Buhler makes several fascinating predictions, the history of propellantless vehicles is replete with outcomes that at first glance appear promising but are ultimately refuted by empirical data.
For example, the EmDrive first showed promise in 2016 when NASA’s Eagleworks team claimed to have measured thrust. Subsequent research discovered no thrust, though.
Prior to rejoicing over this possible discovery, thorough, independent investigation is needed to confirm the findings multiple times. Buhler’s team may have discovered an undiscovered physics quirk, but that’s still a very unlikely scenario.
Even Buhler admits that more research is necessary, saying, “It’s going to take a physicist much smarter than me to come up with all of that.” In his opinion, other scientists are in the best position to evaluate and analyze their findings in order to determine the nature of this recently discovered force.
Space travel in the future? Time will tell.
In conclusion, the scientific community is excited about future advancements and the chance to investigate this possible discovery in more depth.
One thing is certain in the interim: the identification of a novel force that can produce propulsion without the need for propellant has the potential to fundamentally alter space travel and alter our knowledge of the cosmos.
Scientists, engineers, and space enthusiasts alike are excited and look forward to the prospect of a propellantless propulsion system that challenges our current understanding of physics, even though rigorous testing and verification remain ahead.
The future of space travel appears more promising than ever as we teeter on the verge of a technological revolution.
