From another point of view:

Science isn’t easy. It isn’t supposed to be. The process of open publication, peer review and clear data are a part of science because they help us understand how the Universe works. It can be inconvenient and contentious, but it works. Through this process, new ideas are faced with an uphill battle. This is particularly true of ideas that would contradict the foundational theories of physics. So it’s tempting to react to such opposition by playing a different game. Rather than addressing criticism, you start building a story where your idea is obviously right, and others are simply too closed-minded to see it. Down that path lies pseudoscience, and sometimes you can watch it happening. Take for example, Mike McCulloch‘s theory of Modified inertia by a Hubble-scale Casimir effect (MiHsC), also known as quantized inertia.

There are problems with this idea from the get-go. For one thing, the Unruh effect in standard quantum theory is extraordinarily small. If you accelerated a trillion times greater than Earth gravity, you’d only see a thermal temperature of 40 billionths of a degree above absolute zero. Furthermore, since Unruh radiation comes from all directions, it couldn’t create the effects of inertia on its own. But rather than be deterred by this, McCulloch adds other effects into the mix. Since the observable universe is finite, the wavelengths of Unruh radiation is limited, and combined with a cosmic Casimir effect and a bit of information theory, can somehow produce the effect of inertia. The Unruh effect, Casimir effect and information theory are all well established in modern physics, but their hodge-podge combination in MiHsC is misapplied.
