The acclaimed French cosmologist Luminet states in his latest 2008 book 'The Wraparound Universe':
Luminet seems to forget that not only may it be a richer geometry, but that it also may be wrong. The price is also a setting in stone of Newton's oh-much-too-simple law of gravitation and the blocking of a mechanism based on radiated spinning helix particles.
"General Relativity deals with gravity. This no longer is described as a force acting at a distance, but as a local manifestation of the non-Euclidean geometry of space-time. Einstein chose in effect to eliminate the physical action for explaining gravity, paying a price which translated into a needed enrichment of the underlying geometry."

By contrast, particles are proven to exist. Therefore a particle mechanism for the gravity force is the required foundation of modern physics. Is the last 100 years an amazing case of 'groupthink'. When will it get the much needed overhaul?Space-time is a theoretical entity with no basis in physical reality.
