Emdrive might change the law of inertia (for the Earth too!)

EmDrive: UK scientist claims 'new physics' explains galaxy rotation and
theoretical space propulsion:

"British physicist Dr Mike McCulloch, who previously used quantised inertia to
explain how the controversial electromagnetic space propulsion technology EmDrive
works, says that he has new evidence showing his theory can also explain galaxy
rotation, which is one of physics' biggest mysteries.

McCulloch, a lecturer in geomatics at Plymouth University's school of marine
science and engineering, says he now has even more evidence that his "new physics
theory" about quantised inertia works, and that it makes it possible to explain
why galaxies are not ripped apart without using theory of dark matter."
