The EmDrive is Most Likely Not a Warp Device.

Science reporting and science have something of a strained relationship. Whilst most scientists are modest and humble about the results that they produce the journalists who report on it often take the opposite approach, something which I feel drives the disillusionment of the public when it comes to announcing scientific progress. This rift is most visible when it comes to research that challenges current scientific thinking something which, whilst needs to be done on a regular basis to strengthen the validity of our current thinking, also needs to be approached with the same trepidation as any other research. However from time to time things still slip through the cracks like the latest news that the EmDrive may, potentially, be creating warp bubbles.

Warp Capable Craft

Initially the EmDrive, something which I blogged about late last year when the first results became public, was a curiosity that had an unknown mechanism of action necessitating further study. The recent results, the ones which are responsible for all the hubbub, were conducted within a vacuum chamber which nullified the criticism that the previous results were due to something like convection currents rather than another mechanism. That by itself is noteworthy, signalling that the EmDrive is something worth investigating further to see what’s causing the force, however things got a little crazy when they started shining lasers through it. They found that the time of flight of the light going through the EmDrive’s chamber was getting slowed down somehow which, potentially, could be caused by distortions in space time.

The thing to note here though is that the previous test was conducted in atmosphere, not in a vacuum like the previous test. This introduces another variable which, honestly, should have been controlled for as it’s entirely possible that that effect is caused by something as innocuous as atmospheric distortions. There’s even real potential for this to go the same way as the faster than light neutrinos with the astoundingly repeatable results being created completely out of nothing thanks to equipment that wasn’t calibrated properly. Whilst I’m all for challenging the fundamental principles of science routinely and vigorously we must remember that extraordinary claims require extraordinary evidence and right now there’s not enough of that to support many of the conclusions that the wider press has been reaching.

What we mustn’t lose sight of here though is that the EmDrive, in its current form, points at a new mechanism of generating thrust that could potentially revolutionize our access to the deeper reaches of space. All the other spurious stuff around it is largely irrelevant as the core kernel of science that we discovered last year, that a resonant cavity pumped with microwaves can produce thrust in the absence of any reaction mass, seems to be solid. What’s required now is that we dive further into this and figure out just how the heck it’s generating that force because once we understand that we can further exploit it, potentially opening up the path to even better propulsion technology. If it turns out that it does create warp bubbles than all the better but until we get definitive proof on that speculating along that direction really doesn’t help us or the researchers behind it.
