If any of you want a break from shitposting about the mentally disabled, the 1% who live in upscale condos, and Lady Gaga, the following is genuinely cool. Genuinely cool NOT as in "this new rocket is 5% more efficient," but as in "this breaks existing laws of physics if it holds up." Cool enough that I think GBS (and not just SAL) might appreciate it. Anomalous Thrust Production from an RF Test Device Measured on a Low-Thrust Torsion Pendulum Nasa validates 'impossible' space drive NASA claims to have tested a propulsion system that generates thrust without using reaction mass. If this is actually a real effect and not an experimental error of some kind (very possible), it could change space exploration forever. According to classical physics (i.e. Newton's laws of motion), momentum is supposed to be conserved. If you want to accelerate an object in one direction, you have to exert a force by accelerating and ejecting matter in the opposite direction. In space, this is a major hassle, because a spaceship needs to carry propellent that contains both the energy needed to accelerate matter and that matter itself. It's as if an airplane had to carry both jet fuel and all the air that's going to go through the engines. Heavy and inefficient. There are ways to make spaces rockets more efficient, such as ion drives which accelerate a small amount of matter to very high speeds (as opposed to regular chemical rockets, which accelerate a large amount of matter to lower speeds). But an engine that uses no reaction mass at all is something else entirely. If we didn't have to worry about reaction mass, we could potentially build a ship around a fusion reactor that accelerates at a constant rate within the next century, making interstellar travel practical within a person's lifetime. The current theory is that this propulsion system, which uses microwaves, interact with "virtual" quantum particles somehow to generate the thrust. Again, there's a good chance this will turn out to be some sort of experimental error like the faster-than-light neutrino debacle a few months ago, but if this is real, then holy poo poo. The future is truly here.

It's looking pretty iffy still though. They used a 'test article' as an experimental control, which was physically altered so as not to produce any thrust. Unfortunately it produced as much thrust as the 'working' thruster. Add that to the amount of thrust generated being pretty negligable, and it looks like it's just an artifact of the test setup. That having been said, I'm still crossing my fingers for a reaction-mass-less drive. If it does turn out to be true, the free-energy guys will come out of the woodwork though, since it really means getting something for nothing.

They even built a model that did nothing as their control to test in the same conditions and be sure it wasn't something in the testing protocol loving up their results. But it seems like it really works. The next thing they could do is put one in space and see what happens.

About as real as perpetual motion: http://space.io9.com/a-new-thruster-pushes-against-virtual-particles-or-1615361369 They made a null device designed to not produce thrust and measured the same thrust as the "engine". quote:Now, which is more likely? In addition it wasn't "NASA" playing with this, it was a few NASA employees, and what they released wasn't a study or a paper but a bulletin asking for comments.

This would be a good starting premise for a movie or book, but real life is never this interesting. I still haven't heard anything about all that asteroid mining that was supposed to create a golden age or something.

OP, I really wish this was real, but unfortunately the control experiment also passed, so basically the NASA bulitin was just saying "we tested it but our experiment was a total wash". E: where are my manners, I forgot the obligatory dick joke, so I'll just note that your thrusts are as powerful as this device.

Very little has been disclosed about the real Stargate program, so I'd like add to that discussion... Stargate is real so gently caress yer propulsion system quote:Years ago, after watching Stargate, I was fortunate enough to have a lively talk with a very intelligent, highly ranked military officer.
