Bonjour,
En faisant quelques recherches sur l'effet Unruh, je suis tombe sur la theorie de l'inertie quantisee MiHsC (Modification of inertia Hubble-scale Casimir effect) du physicien Mike McCulloch.
J'ai lu un peu sur sa theorie, y compris son blog, et ca a l'air fascinant.
La theorie dit que a masse inertielle est due a l'effet Unruh. Il arrive a expliquer avec sa theorie la matiere noire. Voici l'explication succinte de l'idee:

Voici le papier complet

Il pretend aussi que sa theorie explique l'anomalie de la sonde Pioneer:
De plus il pretend que la theorie peut rendre compte de l'effet Podkletnov :MiHsC predicted a reduction of
inertial mass for the Pioneer craft of about 0.01% which made them more sensitive
to the Sun’s gravity resulting in an extra predicted Sunward acceleration
of 6.9 × 10−10m/s2, in agreement with the Pioneer anomaly.

Est-ce que cette theorie pourrait avoir du sens pour expliquer la matiere noire et la masse inertielle?Abstract
The Podkletnov effect is an unexplained loss of weight of between 0.05% and 0.07% detected in test masses suspended above supercooled levitating superconducting discs exposed to AC magnetic fields. A larger weight loss of up to 0.5% was seen over a disc spun at 5000 rpm. The effect has so far been observed in only one laboratory. Here, a new model for inertia that assumes that inertial mass is caused by Unruh radiation which is subject to a Hubble-scale Casimir effect (called MiHsC or quantised inertia) is applied to this anomaly. When the disc is exposed to the AC magnetic field it accelerates, and MiHsC then predicts that the inertial mass of the test mass increases, so that to conserve momentum it must accelerate upwards against freefall by 0.0058 m/s2 or 0.06% of g, in good agreement with the weight loss observed. With disc rotation, MiHsC predicts an additional weight loss, but 34 times smaller than the rotational effect observed. MiHsC suggests that the effect should increase with disc radius and rotation rate, the AC magnetic field strength (as observed), and also with increasing latitude and for lighter discs.
Merci,
Nicolas.
