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

How QI gets rid of the Gravitational Constant, Big G

Inertia has never been understood, it has just been assumed that “Things keep going in a straight line, unless you push on them”, but why? Quantised inertia (QI) explains why.

This diagram shows an object (the black circle) accelerating to the left. Quantum mechanics states that all accelerated objects see a warm bath of thermal (random) radiation called Unruh radiation (orange) that has now been observed at CERN (Lynch et al., 2021). Relativity states that information from the far right will never catch up to the object since it is limited to the speed of light (c) (the black area to the right). The new assumption of quantised inertia (QI) is that the object & horizon (edge of the black) damp the Unruh radiation between them, as in the Casimir effect (the blue area) so more radiation pushes the object from the left than the right – this model predicts inertia (McCulloch, 2013).


QI also explains galaxy rotation without dark matter, since at a galaxy’s edge the accelerations are tiny so the waves of Unruh radiation get too long to fit inside the observable cosmos (size=Θ), so they cannot exist (Mach: what you cannot ever perceive you should assume does not exist). There is no doubt that it is QI & not dark matter that explains galaxy rotation since the galaxy rotation problems starts at the exact radius where the Unruh waves get as long as the cosmos (McCulloch, 2017). This also predicts a minimum acceleration for nature of 2c^2/Θ.

This is how QI gets rid of the need for the gravitational constant G. The lower the acceleration, the longer the Unruh waves. Physics must act to make sure that the length of the Unruh waves is less than the cosmic diameter, so in any volume there must be at least enough gravity to keep the acceleration above the minimum acceleration, so

GM/r^2 >(2c^2)/Θ

Since Θ=2r and we’ll assume it is on the threshold, then

G=(c^2 Θ)/2M

This relation has long been known to work (try putting numbers in). Now quantised inertia explains it. Since we know the speed of light, c, the cosmic size Θ (to 10%) and the cosmic mass, to within a factor of 10, from counting galaxies, we can calculate G and replace G in all the equations with the right hand side above. This new physics also predicts that G varies in time, as Θ increases. So, next time someone mentions the gravitational constant, tell them it isn't, and furthermore that it is not needed at all!

A Quantised Inertia Drive is to be Launched to LEO by SpaceX

I’ve been in the ‘New Physics’ arena for 17 years now, and things keep getting weirder. When I started out in 2006, peer reviewers of my early papers were of the opinion that they didn’t exactly believe QI but it was more likely than dark matter, they could not find anything logically wrong and the theory agreed with the data, so that was that. In other words, they put logic and facts before mere opinion.

Today, an article appeared on Universe Today (see below from the Wayback Machine) reporting two factual events that I’ve had to keep quiet about for months due to an NDA (Non-Disclosure Agreement). The first is that a US company that I have been liaising with, called IVO Ltd, tested a QI thruster in a professional vacuum chamber and found it to agree with the QI theory. The quote from IVO CEO, Richard Mansell was “All Quantum Drives showed thrust consistent with predicted Quantized Inertial calculations. Control Drives confirmed that thrust measurements were not consistent with any other known forces.” The second piece of news was that they are to launch a QI drive on a SpaceX rocket on June 10th for a test in space. I was pleased that at last I could talk about these two pieces of news, but a few hours later the article had been deleted due to pressure apparently from ‘some physicists’ who doubted the QI theory. 


Who are these titans of physics who can erase facts that threaten their opinions within a few hours?! That would be like suppressing all news of the next SpaceX launch because you don’t believe in space: let them at least test the idea. Let’s hope this essay does not also magically disappear...

The article has of course been saved by the great Wayback Machine: Link

Kudos to Universe Today. They have republished the article with more balance. 'Tis here: Newlink
