Scientists have been coming up with new ideas to explain how the controversial propulsion system works.
The electromagnetic propulsion engine, which some scientists believe could herald a new era of spaceflight by replacing conventional chemical rocket engines, has been a hot topic recently.
EmDrive allegedly works by converting electrical power in to thrust without the need for propellant through a process that scientists argue is in direct violation of the laws of physics.
Now in a renewed effort to understand exactly what is going on inside the controversial engine, researchers have been mulling over possible explanations for its peculiar behavior.
