While every chance should be made to further explore our current assumptions (such as with the LHC), we shouldn't be neglecting low hanging fruit that challenges our ideas (such as the EMDrive). If as much as 1% of the money that is being spent on LHC went to "anomalous science" we'd likely have a conclusive answer on whether the EMDrive doesn't work. Science is tool that disproves, and we've been hacking it into a proofing tool for far too long. It's time to go back to basics and figure out more about what we don't know.
> McCulloch’s theory makes two testable predictions.
Think about the cost of either of those experiments - vanishing in the face of other science that is being performed today. If science wants to see the EMDrive go away, and is certain that it doesn't work, a comparatively small grant is all that it takes.
