I've suggested (& published in 21 journal papers) a new theory called quantised inertia (or MiHsC) that assumes that inertia is caused by relativistic horizons damping quantum fields. It predicts galaxy rotation, cosmic acceleration & the emdrive without any dark stuff or adjustment. My Plymouth University webpage is here, I've written a book called Physics from the Edge and I'm on twitter as @memcculloch

Bozeman, Montana or TU-Dresden?

This is a summary of the visit I have just made to Prof Martin Tajmar's esteemed Institute fuer Raumfahrttechnik at the Technische-Universitat-Dresden (TU-Dresden). I arrived on time at 10am. One of his students met me and took me to his office and then after a short chat, I gave a one-hour talk on quantised inertia (QI) to him & his research group of 30 or so. Martin Tajmar asked a few questions, eg:
  1. How does the cosmic horizon interact with local dynamics in QI given the speed of light limit? (Answer: there is no relativistic speed limit for monochromatic waves).
  2. Your assumption of an average acceleration of photons in the emdrive is wrong, they accelerate only when they rebound (Answer: true, but my assumption now has more backing, see below).
  3. What is the degree of shielding of Unruh radiation by matter? Won't that introduce an adjustable parameter to QI? (Answer: Maybe).

After the talk we all went for a meal at the nearby canteen, and I made it clear, as I tried to do in my talk, that I am very confident about quantised inertia on a galactic scale, but I need Tajmar and his team's world-class experimental expertise to bring it down to the lab scale.

Then he gave me a tour of his labs, in which he seems to be testing most of the anomalies I have heard of. I saw the equipment he used for the 'Tajmar effect' that I tried to explain in a paper in 2011 (see refs). It is still embedded in its concrete well. I held his small emdrive. He also has a massive wind tunnel for more mundane aeronautical experiments. At one point he said "And here is my Stargate..". I looked through a window and saw a huge room in which he is building something that looks like the fictional stargate (it's not).

Back in his office, a student who has just started a PhD devoted to the emdrive gave a talk on recent progress. They have applied 3-10 Watts to an emdrive and measured a thrust of two microN, but it disappears when they subtract thermal changes due to an asymmetrical expansion of the cavity and the resulting changes in the centre of mass. Note that this is a thrust ten times smaller than the thrust NASA JPL was getting for a similar power and this work is still in progress.

We talked about Travis Taylor's mirror proposal. It may not be possible to build as originally proposed, due to the dielectric and mirrors not being able to fit together - manufacturing limitations. So they suggested a simpler arrangement where the dielectric and mirrors do not touch.

Martin then said "We are physicists, let's play" and started writing on a white board, asking me for the relevant QI formulas to put in, and this way, we derived the maximum acceleration of a photon of given frequency. The result was interesting because it means that for visible light bouncing off a mirror the Rindler horizon will be so close that a shield will not effect it, but it also shows that for microwaves the horizon is cavity-sized, so they can see the emdrive shape, or a shield.

The most unexpected thing that Martin said to me was in the evening while socialising (I had some delicious Saxische Sauerbraten and dumplings, and rather more than my usual amount of beer). He criticised most of the well-known lab anomalies as being debatable due to often sloppy technique, and yet showed some interest in an anomaly I thought had been wildly discredited: Hutchison's. I thought I'd had too much beer.. Good physics is of course predictive, but the profession itself is not!

Quantised Inertia Needs You!

It was not long ago that I myself was trying to get a full time post, now, not only do I have one but I am offering a post-doctoral position. So, if you are good at the numerical modelling of the interaction between em radiation and physical systems, preferably using COMSOL/Java, you fully understand what is behind the terms Unruh radiation and Rindler horizons, and you are keen to help with the conquest of space by helping to develop an 'electric rocket' for much safer, cheaper launch and propellant-less thrust in space (ie: saving both the planet and the human race) then this job advert is for you:

Research Fellow in Modelling Propellantless Thrust, University of Plymouth, UK.

We are seeking an enthusiastic postdoctoral researcher with excellent skills in physics & numerical modelling, to develop a predictive model based on a ground-breaking theory called quantised inertia. The numerical model will be used to design a new kind of thruster.

The new theory suggests that inertia is caused by an interaction between Unruh radiation and matter. It explains, for example, galaxy rotation without dark matter, but in order to enable accurate experimental tests of the theory, it must be fully coded into a numerical model that can predict exactly how Unruh radiation will push on any given configuration of matter. Your role will be to do this coding.

You must have a PhD in physics, experience in translating physics into numerical models, an understanding of the interaction between radiation and matter, quantum mechanics and relativity. Experience of COMSOL and java will be an advantage.

You will work with Dr Mike McCulloch. The post includes short trips to Dresden (Germany) and Madrid (Spain) to liaise with groups who are setting up experiments.
