It gives a Lorentz Factor of 1.0008.

So the time dilation is basically negligible.

Even at half the speed of light you only get a Lorentz Factor of 1.15. The velocities required for large time dilations are massive.

Also have huge doubts as to these findings. Had heard of them a while back when NASA and China did tests and not any more convinced now. It is most likely just measurement errors like what happened with the faster-than-light neutrino.

I'd rather focus on the fantastic "maybe" than the status quo "probably not". I'd rather the world keep at stuff like this with hopeful optimism until it's totally debunked, than simply going with an attitude like

“My insight is that the EMDrive is complete crap and a waste of time,” Carroll tells io9. “Right there in the abstract this paper says, ‘Our test campaign can not confirm or refute the claims of the EMDrive’, so I’m not sure what the news is. I’m going to spend my time thinking about ideas that don’t violate conservation of momentum.”


as was linked in an earlier article. There's a thing we've got here that's producing weird results so let's account for those fully. If things are as we think we are and we can't get thrust without propellant, oh well it was an interesting problem to work through. If things aren't as we think we are, well oh well at one point we thought the sun went around the earth and it was perfectly reasonable to think given the evidence we had before that.

Exciting if it becomes practical.
