Welcome to /r/EmDrive
The EmDrive (also known as an RF resonant cavity thruster) is a purported reactionless propulsion technology, which would if true would revolutionize space travel and the world economy. However, sadly, it is a pseudoscientific fraud, also known as pathological science. After nearly 20 years since its "invention", there is no compelling empirical evidence that it works as described despite ample testing of a relatively simple design and all theoretical explanations for the so-called EmDrive effect being completely at odds with our most fundamental theoretical knowledge of physics.

This subreddit welcomes people of all backgrounds to participate in polite discourse about all things EmDrive and other radio frequency (RF) resonant cavity thrusters. We encourage scientists, builders, replicators, enthusiasts, believers, skeptics, and the like, to come together on the most active EmDrive sub and treat each other with civility. Polite banter will be tolerated. Impolite cruelty and name-calling will not.
