NASA peer reviewed paper showed that they had tested the propellentless EMdrive propulsion on a highly sensitive device in a vacuum and detected 1.2 millinewtons per kilowatt of propulsion.

Many remain unconvinced.

Despite having a setup that has been pretty much operating for years, how many data points are in the paper? Eighteen. Now, if this were a really time-consuming experiment, I wouldn’t let that bother me. Hell, some synchrotron experiments have only a single data point. But this is clearly not a time-limited experiment.
