Four Books!

So far, I have written four books that cover quantised inertia, among other things like the scientific method and what it is like to be a maverick scientist, from various points of view.

I was invited to write my first book, Physics from the Edge (2014) by World Scientific. The title had three meanings. First of all, quantised inertia's main claim is that the cosmic edge (horizon) affects inertia here, so it is indeed physics from the edge of the cosmos. The second meaning is that I felt myself to be on the edge of the physics community. The third meaning was an allusion to Carrie Fisher's Postcards from the Edge... partly because I always fancied Carrie Fisher. The book introduces QI and some applications of it. You can get a good feel for the early years of QI. The theory was slightly different back then. Many things have improved but some nuances have been lost. It is expensive though, as it was publish as a monograph.

My second book (2021) was called Falling Up. It is a sci-fi novelette, published on Amazon. I wrote it, off and on, from about 2004 to 2021 so it contains bits from the entire history of QI. The antigrav lab scene, for example, was written before I derived QI and was living on a station platform (in a tiny flat I must add!). It has many good reviews on Amazon and 4.7 stars. One reviewer said that "If Frank McCourt was to write a sci-fi novel it would read something like this." Excited by that comment, I read his novel, Angela's Ashes, and it seemed almost grammarless! I'll take it as a compliment anyway.

My third book (2023) was called Hacking the Cosmos, and is also a novelette. It was written more recently, as you will see from the social environment I describe. It introduces QI from the new information standpoint and also describes the feeling of alienation from the physics community that I've felt, almost as if I was indeed guilty of destroying the cosmos. I refer to some of the relevant QI papers in the book.

My fourth book (2024) called Quantised Accelerations is the second QI textbook and was published by Robert Zubrin's Polaris Books. I wanted with this one to demonstrate the old empirical approach (i.e. genuine science) that has been almost entirely lost in these times. The book starts by discussing 54 anomalies that cannot be explained by modern physics. It then introduces QI, and shows how QI explains most of the anomalies. I also discuss applications: thrust, power and interstellar travel, and some consequences for philosophy. I wrote it to be accessible, there are equations, but they are simple, and I drew cartoons and schematics to help explain the ideas. It is still selling well and has 4.7 stars on Amazon.

I have loved writing them, and I hope you enjoy reading them.

A Potted History of QI

2001. Trigger moment. Perhaps this is the point at which it all began. I was working at the Met Office. After the angst of post-docs, a secure ocean modelling research job meant I was able to branch out a little. On 6th February for various reasons I had to hide in the library and there I read about a paper of Haisch, Ruella and Puthoff in New Scientist, wherein they attributed inertia to the zero point field (zpf). I loved the approach. Later I realised it was wrong since they have to hard-wire an arbitrary cutoff to get rid of a background zpf, so I developed Quantised Inertia instead which relies on zpf gradients so is not affected by absolute values. This is my method: to not allow anything arbitrary into a theory.

2006. Pioneer. The first paper on Quantised Inertia. I showed that if you assume that inertia is due to Rindler horizons damping Unruh radiation (an excited quantum background / zpf) then this predicted the Pioneer anomaly, the cosmic mass and various other observed oddities.

2012. Galaxies. For a long time I was unable to work out how to apply QI to galaxies, they are more complex than lone spacecraft, but I worked out how to do it in this paper and showed dark matter is emphatically not needed. I did it in more detail in a paper in 2017.

2013. The mechanism. I proposed for the first time a beautiful and direct mechanism for the inertial mass we all know and love. When an object accelerates in one direction, is sees a relativistic horizon in the other direction. This horizon damps the quantum background creating a quantum gradient that pushes back on the object giving it inertia. i.e. inertia is not intrinsic to the object but due to external quantum forces. You might say this is ‘mass without mass’. I also mentioned how to make objects move without propellant: by making artificial horizons (bits of metal).

2014. Textbook1. My first textbook on QI was called Physics from the Edge: full of anecdotes, equations and a few cartoons. It was published by World Scientific, but was not the mass market breakthrough I needed because it was priced as a monograph and too expensive.

2015. I had a go at predicting the apparent thrust of Shawyer’s emdrive and QI seemed to predict it very well, especially the effect of adding dielectrics to the cavity. I took this as evidence that my musings on propellant-less thrust in 2013 were not idle.

2017. DARPA said they ‘had been watching me for some time’, and came to visit. I was given $1.3M to test for thrust in the lab. My papers on the emdrive and dielectrics reminded a smart engineer called Frank Becker of some anomalous capacitor tests he once did and he teamed up with Ankur Bhatt to do some tests. In liaison with me they found thrust and then so did other labs including one I set up at Plymouth with a great engineer called Richard Arundal (fun times!).

2019. My Spanish post-doc Jesus Lucio and I published a paper showing that only QI can explain the orbits of wide binary stars. I loved working with Jesus (as I did with Richard).

2020. Unruh Radiation is Real. Michael Lynch and his team made the first observation of Unruh radiation in positrons decelerating in crystals at CERN, and kindly emailed me in some excitement to tell me. This was good news since I’ve been depending on the existence of Unruh radiation for 14 years – it’s essential to QI.

2023. Space Test. A forward thinking company called IVO Ltd and led by Richard Mansell (a thoroughly decent guy you can’t help but admire) tested a Becker and Bhatt style capacitor in a professional vacuum chamber and saw QI thrust. They then launched a test into space! Unfortunately, the cubesat was lost before the test could be made but they’ll try again in 2025.

2024. Textbook 2. This year I've shown that only QI can explain the orbit of Proxima Centauri, our nearest neighbour in space, which orbits Alpha and Beta Centauri far too fast. I also completed my second textbook, published by the great Robert Zubrin, who is himself a force of nature. I made sure this one was a lot cheaper than the first and it is selling well. In it, I point out 54 anomalies that old physics cannot explain, introduce QI, and show how it predicts these anomalies. I also propose how it could produce new clean energy sources and how it not only explains the orbit of Proxima but how QI thrust could get us there in 10-15 years.

It's been a great adventure, but the best is yet to come...

My New Book: Quantised Accelerations

These are exciting times for Quantised Inertia (QI). I've just published a paper, my first in three years, showing that the only dynamical model that can predict the orbit of our closest neighbour in space, Proxima Centauri, is, surprise, surprise QI! This paper was just accepted and published by the Monthly Notices of the Royal Astronomical Society no less (see references).

Also, my new book on quantised inertia is available from Amazon next month, on the 15th July (see references). I've been working on this book for seven years, and it is, I hope, nothing less than an empirical reboot for theoretical physics. Like Gaul, in Caesar's eyes, the book is divided into three parts:

In the first part I have no mercy on the standard model of physics and I discuss 54 observed anomalies that prove that the old physics just can't cope anymore. These range from the large-scale cosmic acceleration which makes a mockery of any pretence of conservation of energy in physics, down through the well-known galaxy rotation problem that gave rise to the need for the awfully arbitrary dark matter, the wayward asteroid Oumuamua, down through laboratory thrust oddities, the Abraham-Minkowski paradox, the long running controversy of cold fusion and the proton radius anomaly. This is a scale range from 10^-15 to 10^26 metres.

Then, just when you are giving up hope that any physics can explain these diverse anomalies, I introduce quantised inertia and show that it predicts what people have been calling the usual property of inertia, but with a slight change that predicts the anomalies as well. It gets rid of the gravitational constant, which turns out to be the speed of light squared times the cosmic scale divided by its mass. Happily, one less constant to learn at university (I always found it to be a perfectly acceptable constant but with Frankenstein units).

Just as you are breathing a sign of relief that physics might look up from its invisible entities and untestable strings, I introduce all the applications of QI which include much better satellite thrusters, the ability to get to Proxima Centauri (yes, the same) in less than 15 or so years, self-thrusting materials, FTL comms and a possible way to generate energy from it.

My overall goal is to put physics back into its best mode: first look, then think, then get busy!

The Hubble "Tension"

If you say boo to a goose and it flies away, rather than attacking you as they used to at York University, then the sounds you hear coming from it will shift to a lower frequency as the waves from your point of view are spread out. This is the Doppler effect and applies to light waves as well. As we know, Edwin Hubble noticed that the light from distant galaxies was red shifted, that is, the wavelength of the light we received from them was longer, implying that the galaxies were moving away from us and that the further ones were moving away faster than the closer ones. This was taken to mean that all the galaxies were moving away from a common centre as if there had been a Big Bang (or a Big Boo) 13.6 billion years in the past.

Looking at local galaxies, the Hubble expansion rate has been measured to be 73 km/s/Mpc. That is, galaxies one megaparsec (Mpc) away from us are apparently moving away from us at 73 km/s.

Recently, a new method was devised to calculate the Hubble constant from observations of the Cosmic Microwave Background, that represents the cosmos long ago at a redshift of Z=1000, and then extrapolating forward using standard models assuming dark matter and dark energy. Perhaps not surprisingly they got a different answer: 67.7 km/s/Mpc.

This discrepancy is now much bigger than the uncertainties in these two numbers, so it is significant (Reiss et al., 2019). As is usual in physics now, to avoid offending anyone, this is called "The Hubble Tension", but in fact it is a falsification of the present model (as stated, the difference is larger than the error bars).

What does QI have to say about this? Well, there is an interesting link up. If you look at the difference in these speeds you get 73 - 67.7 = 5.3 km/s/MPc. Scaling this up to the speed at the edge of the cosmos you get 155,000 km/s and if you calculate an acceleration from this by dividing by the age of the universe you get

Acceleration = 3.8x10^-10 m/s^2

This is the mutual acceleration of both sides of the cosmos and we just want that of one, so when we divide by two we get about 2x10^-10 m/s^2. Those who know about quantised inertia, QI (surely most of you reading by now) will see immediately that this is the minimum cosmic acceleration predicted by QI as 2c^2/CosmicScale = 2x10^-10 m/s^2. So maybe the Hubble "Tension" is just the fact that they left QI out of their model!

Note that there is probably more to this, as I'm not sure I believe in the physical acceleration model either, but you must admit this does all fit rather well!

The 18th Birthday of Quantised Inertia

Recently, last Thursday, it was the 18^th Birthday of Quantised Inertia. Back then, in 2006 I was a humble ocean and wave modeller at the UK Met Office in Exeter, with a hobby of thinking about physics in the evenings. It was on the 1^st February, 2006 that I first realised that Newton’s First Law was slightly wrong (ie: QI) and that this was a big step

I gave my first talk on QI (then I called it MiHsC) later that year at the Alternative Gravities Conference at the Royal Observatory in Edinburgh where I had the last talk, and I nearly did not get to speak as they all wanted to go to the pub! In 2007 I published the first paper on QI. One of my colleagues at the Met Office told me I shouldn’t have such grandiose dreams, weathermen should stay below Karman Line. I submitted anyway and my first paper on QI was accepted by MNRAS (a prestigious astronomical journal). The reviewer was delightfully amused that I’d used the term ‘forecast’ instead of ‘predict’ and did not quite believe QI, he said, but he also said it was better than the alternatives he'd seen already published, so why not publish?

By 2008, I’d published enough papers to leave the Met Office and get into academia at Plymouth University, lecturing in geomatics (the maths of positioning in space) which was a subject vague enough to fit. I enjoyed the teaching, and my courses on GPS Positioning stimulated me to develop a better way to formulate QI, using uncertainty in position and information. I finally managed to show that QI predicts galaxy rotation without dark matter which is a massive result, and very clear in that even the onset of the anomaly is predicted well, and I was invited by World Scientific to publish a monograph.

In some papers I mentioned producing thrust from QI, and a few years later DARPA got in touch (2016), said they'd been "following my work for some time", and invited me to apply for funds. I applied and won $1.3M to test for what I’d predicted: thrust from highly accelerated objects in cavities. We first tried photon cavities. I used labs in Germany and Spain, which I was soon unable to visit due to covid, but the photons were too light (pun intended) to work. Fortunately along came engineers Becker and Bhatt who'd read my papers and they suggested electron cavities instead (capacitors). That seemed to work in their lab and IVO Ltd (Richard Mansell) confirmed and improved on it. I managed to get DARPA funds to Plymouth to replicate it with engineer Richard Arundal (a paper is in review) and now IVO have launched a test into space via SpaceX and Rogue Space Systems! Another recent development is that Lynch et al. (2021) have finally confirmed Unruh radiation using CERN data. Morgan Lynch emailed me excitedly to tell me. This is good for QI, which has been assuming its existence for 18 years!

Now I am temporarily between jobs, busy with new QI books (one sci-fi and one text book) and papers, but given the crazy acceleration of the past few years, there is some relief in pausing to decide how best to progress. QI (my hobby) is so big now: a radical change to physics, thrust, clean energy, interstellar travel... It needs development for the sake of getting humanity to the next level, yes, but to avoid burn out I do need to get back to the feeling that this is a deep scientific exploration & not just the race of all time.

Keep Calm and Quantise Inertia!
