SpaceX are launching this drive in October, so let's see if we will be rewriting physics or not.

Very interesting, Martin!  I was testing my Super Methane producing engine the other night.  Lit a match and I was out to Jupiter and back in no time!  🚀  After eating my super chicken 🌯

Great find, Martin. I am working on research projects that are reasonably close to this quantized inertia (QI) hypothesis, and I was not aware of it. That means that this idea is certainly not main stream and generally known or accepted. Having said that, work on QI has been published in journals with proper peer review, which means it has already passed some sanity checks. However, it is also greeted subject to skepticism; see, for instance, https://academic.oup.com/mnras/article/489/1/881/5545603

The next logical step would be experimental evidence. I am looking forward to the SpaceX launch 🙂

The physics in this article is, of course, completely beyond my ability to understand but I noticed that the value used for the Hubble Constant is quoted as Ho = 2.3 ± 0.9 × 10^−18 s^−1. How is this related to the value of 70 km s^−1 Mpc^−1 which we usually see?

It's the same, just expressed in different units. Mpc stands for Mega Parsec, which is a unit of distance. Hence, km Mpc^-1 has no physical units since it is a ratio of distances. To be more precise, 1 Mpc = 3.2 million light years, and one light year is about 10^13 km. One Mpc is roughly comparable to the distance between us and the nearest spiral galaxy (Andromeda).

Intuitively, the Hubble constant describes how fast the universe expands. Imagine you have a ruler that is initially 1m long bot grows by 1cm per second. The corresponding Hubble constant would be (1 cm s^-1 )/ 1m = 0.01 s^-1. The real constant is much smaller (2.3 * 10^-18 s^-1), but to compare that with astronomical observations, it is easier to express it in the way that every Mpc grows by about 70km every second.
