The Wizard of Oz . <| sep |> More than 5 different universities have already verified these engines . They record anomalous thrust , but there is no understanding of where that thrust is produced . The results that made this popularized in media were late to the game , these have been around for decades and the team from NASA got involved after a university from China released their findings , which were then followed up by numerous universities around the world including several in the US . The original paper that made all the headlines was newsworthy not because it was new or unique , but that the expected result of the nulltest covering the ports should have resulted in no thrust but it did not . That led to lots of wild speculation which is what media loves to do .
