>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.

In the physics community theories that reject dark matter are broadly considered pseudoscience and theories that reject WIMPs are broadly considered unlikely to be true.
