<p>The whole point of Einstein's equivalence principle (in all its variations) is that gravity is not a force in the same way that the electromagnetism, or the weak and strong interactions give us forces. The fundamental idea is that we are weightless in free fall local inertial frames (on time like geodesics in curved spacetime without rotation about our centers of mass). Therefore, the force of gravity in the sense of Newton's 17th Century theory is locally eliminated. Therefore, whenever we f...Jack SarfattiMon, 31 May 2010 01:40:10 +0100REVIEWS OF MODERN PHYSICS, VOLUME 82, APRILâ€“JUNE 2010 Nano-Tech Quantum Noise

<p>The problem of why the Pioneer Anomaly's anomalous acceleration is the same order of magnitude as the square root of the dark energy density though in the wrong direction has bugged me since 2002. Of course both dark energy and dark matter density are same order of magnitude .73 vs .23 of critical density for a flat space universe found in the inflation model.
