NASA confirms ‘impossible’ thruster actually works

In summary, recent articles have reported on NASA's confirmation that an 'impossible' space thruster actually produces thrust, potentially revolutionizing space travel. However, the evidence for this is based on a conference paper which has not been peer reviewed and was tested in an iterative manner with manual frequency control. The authors also could not reject the null hypothesis, suggesting this may be just a null result.

These articles are all over the place the last couple of days. Yours appears to be a near carbon copy of an article at gizmodo, which in turn got their article from the Spanish gizmodo site, which in turn got their article from The UK Wired site. This would be better as a study in poor scientific journalism than a question about fringe science.

Note very well: We don't discuss fringe science at this site.

All of these articles are based on a recently presented conference paper: http://ntrs.nasa.gov/search.jsp?R=20140006052. This is just a conference paper; we can reject it just on that basis. Conference papers do not count as peer reviewed scientific literature. What's worse, from the paper, emphasis mine,
Integration of the two test articles and their supporting equipment was performed in an iterative fashion between the test bench and the vacuum chamber. In other words, the test article was tested on the bench, then moved to the chamber, then moved back as needed to resolve issues. Manual frequency control was required throughout the test. Thrust was observed on both test articles, even though one of the test articles was designed with the expectation that it would not produce thrust. Specifically, one test article contained internal physical modifications that were designed to produce thrust, while the other did not (with the latter being referred to as the "null" test article).
The authors couldn't reject the null hypothesis. This might we be just a null result, which is exactly what should be expected.

Related to NASA confirms ‘impossible’ thruster actually works

1. What is the ‘impossible’ thruster and why is it significant?

The ‘impossible’ thruster, also known as the EmDrive, is a propulsion system that was first proposed by British inventor Roger Shawyer in 1999. It is significant because it claims to produce thrust without the need for any propellant, defying the laws of physics.

2. How does the EmDrive work?

The EmDrive uses microwaves to create thrust by bouncing them back and forth inside a closed, cone-shaped chamber. This creates a difference in momentum, resulting in a net thrust in one direction.

3. What evidence does NASA have to support the EmDrive’s functionality?

NASA conducted several experiments to test the EmDrive, including a peer-reviewed study published in the Journal of Propulsion and Power. The results showed that the EmDrive did indeed produce small amounts of thrust, although the reason behind this is still not fully understood.

4. What are the potential implications of the EmDrive if it is proven to work?

If the EmDrive is proven to work, it could revolutionize space travel by providing a more efficient and cost-effective propulsion system. It could also potentially lead to new advancements and discoveries in physics.

5. Is the EmDrive technology ready for practical use?

Not yet. While the initial results are promising, more research and testing are needed to fully understand the mechanics of the EmDrive and improve its efficiency. It is also important to note that the EmDrive has not yet been peer-reviewed by the wider scientific community.
