The Shawyer EM drive is not dead but now has serious competition… using lasers. This is almost a breakthrough but has not attracted much attention so far..

What’s with NASA dropping something like this??? Almost unforgiveable. Fortunately DARPA/ARPA did not give up and the latest results seem to be fabulous (when and if they are duplicated). Long video from Mike McCulloch https://youtu.be/341Yk4k51uY >From the Next Big Future comments: This is related to Mike McCulloch's >“quantized inertia” QI theory which itself is related yet different from the >usual Mach effect and Emdrive drama. McCulloch has a theory for inertia that predicts galaxies' rotation sans dark matter, distant binaries and other anomalies presumably without adjustment, and it has other several interesting implications. It explains the Emdrive and predicts several kinds of inertia-based drives using EM waves of different efficiencies…. To call it controversial is an understatement. In a way it is refreshing to get rid of the baggage of dark matter. It has always smelled a bit like a klutz concept… unless of course it is the “aether”
