A few days ago an article appeared in Forbes magazine directly criticising me and quantised inertia. I understand that after working for decades on dark matter, many find quantised inertia difficult to accept. I do hope to persuade them slowly, but a debate should be based on empirical evidence and this article did not present any. It also misexplained quantised inertia, and vaguely attacked my attitude, so I need to answer it.
For example, the article accuses me of not addressing criticism, but all the comments I have received from the mainstream say I am violating a theory that only predicts 4% of the cosmos (in some sense). What exam can you pass with a mark of 4%? What matters to me is whether I am violating empirical data. No-one has shown that. It is true that I need to show how quantised inertia might fit together with general relativity, but that is a far lower priority than comparison with data, and to compare QI with GR some communication between me and general relativists needs to begin, but it has been cut off, and not by me. I haven't been accepted at a physics conference since 2012 and most physicists have refused my attempts to engage by email.
The article claims I am on some sort of mad slide into pseudoscience, but if you look at the facts: in every one of my 17 published papers I have tested quantised inertia against real data, and it worked without adjustment. In contrast there has never been any direct evidence for the dark matter the mainstream believe in, and the hypothesis is nothing but adjustment. So you have to conclude that it is the dark matterists who have been on the slide into pseudoscience for decades and the only reason they haven't noticed is they are all happily going down together, so self-correction has become impossible.
The article claims that Unruh radiation is so small it is incapable of generating an inertial force, but the author has not understood my papers: I have shown quite simply that when it is made non-uniform in space by relativistic horizons, Unruh radiation does produce the right amount of force. Please see this paper: preprint and a later one where Dr Jaume Gine corrected an error I made to give better results: journal.
The emdrive thrust (which QI predicts) is not "within the noise" as the article claims. The NASA emdrive paper went through five reviewers before being published. Of course, they and all of us may have missed some mundane effect we don't know about yet, but to suggest that all five reviewers do not know noise when they see it is implausible. Noise does not usually pass peer review.
The article says “How strongly verified [mainstream] theories are”. I have received such comments from many reviewers, especially recently, and I can never understand how this can be said with a straight face: mainstream theories predict only 4% of what we see. If that is 'strongly verified' than those words must be in a different language.
The article claims “This hodge-podge is misapplied”. How easy it is to say something like that, but what data proves it is misapplied? It is not enough just to say it and hope that people won't bother to think. Words must be supported by data, but there is no supporting empirical evidence anywhere in the article.
The article says QI “Overturns basic/established physics”. Well, I realise the difficulty of doing it, and do not take it lightly, but it is absolutely fine to modify fundamental physics so long as experiments are still satisfied, and they are. Quantised inertia has only a tiny effect in normal regimes, but it changes things in very low acceleration regimes, which is exactly where normal physics fails. It allows us to predict not 4% of nature, but much closer to all of it, offering an explanation for anomalies at low accelerations such as galaxy rotation and cosmic acceleration. Basic physics is self-contradictory anyway. We know its two halves (GR and quantum mechanics) do not fit together either formally, or causally with Bell test experiments. Quantised inertia allows us to fit it together a little more since the whole point of it is that relativity and quantum mechanics work together to make inertia.
Towards the end, the article bizarrely seems to accuse quantised inertia of being too successful, since it explains so much. First of all, since when is empirical success a crime? That is taking scepticism too far, and that does no-one any good. Also, the reason QI fits these anomalies, as well as the standard data, is because I designed it after looking at new data with an open mind. In my opinion, and I think history shows, that is exactly the right way to advance science and it is what the dark matterists have forgotten.
Quantised inertia is far from complete. It is an approximation to a full theory that I do not have yet. I need the help of other physicists and their great skills to look for the phenomena it predicts (see here) and flesh out the theory. The problem I have is the excruciating one of trying to persuade extremely well-educated and driven people, that I have no desire to antagonise at all, that they are wrong in this one matter, and enlisting their help (which I need) at the same time! If they wanted evidence for my lunacy then they could cite my hopeless optimism in this social respect.
My crucial point remains empirical: quantised inertia agrees with the data more simply than MoND or dark matter (see here for example). There is no way to get away from that fact. They can claim I'm a lunatic with delusions of gradeur (maybe I am, it is not for me to say) but after it all the mass of data that support quantised inertia will not go away, and in the end it will save all of us.
