This is sort of like "Cold Fusion", except it has stubbornly resisted attempts to falsify the results. It it works, it will change...well..IMO, just about everything, in time.

An Alternate Theory of Inertia
The theory of QI was first proposed in 2007 by University of Plymouth physicist Mike McCulloch as an alternative to the Lambda Cold Dark Matter (LCDM) model. This theory was an attempt to reconcile General Relativity (GR) and Quantum Field Theory (QFT) to explain the rotational curves of galaxies in a way that did not require Dark Matter (and as an explanation for the Pioneer Anomaly). The theory comes down to two essential elements:
According to GR, there is an event horizon in the Universe where light cannot reach an object because cosmic acceleration exceeds the speed of light. A similar horizon is produced if an object accelerates in one direction (known as a Rindler horizon). Anything beyond this is outside the observable Universe and cannot affect the object at the center of the “Rindler space.”
According to QFT, similar radiation is predicted for an accelerating object (Unruh radiation). QI posits that Unruh radiation is the origin of inertia. Similar to the Alcubierre Metric (but on a larger scale), the Rindler information horizon expands in the direction of acceleration and contracts behind it.
