Humanity has long understood the universe. We have a physical framework that Mostly This matches our observations and new technologies allow us to analyze the big bang and take pictures of black holes. But the hypothetical EmDrive rocket engine threatens to augment what we know about physics… if it works. After the last round of testing, we can confidently say that there is no.
If you have memories from the 90s, you probably remember your interest in cold fusion, a chemical process that is supposed to produce fusion energy at room temperature instead of millions of degrees. (Pick your favorite size, all numbers are huge.) EmDrive is a cool fusion for the 21st century.First proposed in 2001, EmDrive uses an asymmetrical resonator channel where electromagnetic energy can bounce around. Exhaust, but proponents claim that EmDrive creates thrust
The idea behind EmDrive is that the tapered shape of the cavity reflects radiation in such a way that a large net force acts on the reflector at one end. Therefore, objects can be used This “engine” is for high performance driving. That would be a direct violation of momentum conservation.Interests in EmDrive were scattered until 2016, when NASA’s Eagelworks lab built a prototype and tested it. According to the team, they detected a small net force. But measurable and that Someone interested
There was a lot of skepticism about the Eagelworks results, and the other team was unable to replicate the results.A team from Dresden University of Technology conducted a comprehensive new test, trying to replicate the results from Eagelworks, and they found nothing – The zero thrust is generated by the Dresden EmDrive when electromagnetic radiation bounces around inside the resonator.
The team also tried to explain the Eagelworks results, which were done by designing different experiments. Dresden researchers used better measurement techniques to show that EmDrive was not generating the drive. But by scaling, measuring, and changing the resonator suspension points, they are getting the same clear thrust as NASA does.That’s confirmation that the Eagelworks’ thrust is just a thermal effect. The researchers also speculated that the Eagelworks picked the data by reporting random fluctuations in a way that did not represent the entire dataset.
This is really the end of the road for EmDrive.Without anyone able to pinpoint the massive physics elements that we have missed, there is no way this engine will function as described, the EmDrive proponents have to contain it unless they want to. Ends like a cool fusion crank from the 90s, that’s just science in action. But it’s a little boring, because EmDrive will change the world, if not fantasies.
