We know that in QM and QFT, spacetime is given, fixed, nondynamical stage.(adsbygoogle = window.adsbygoogle || []).push({});

We know that gravitons framed as a QFT can give rise to GR as an effective field theory.

how do we know that spacetime geometry is dynamical independent of its effects on fermions and bosons? perhaps gravitational lensing is not the result of curvative but gravity-particles.

What's the difference between stating that gravity is a manifestation of local spacetime geometry, and

gravity is a particle field of gravitons, moving across an eternal, timeless, shapeless, non-dynamic, inert minkowski type background, that interacts with everything, including matter and energy, in a curved-path manner? time dilation is the result of gravity fields interacting with fermions/bosons, not curved spacetime.

Therefore, Smolin and LQG's quest for BI is wrong and misguided. Gravity is a field, that interacts with other fields, that exist as a part of spacetime, not spacetime itself, and is not quantized. Lorentz invariance holds below the subplankian regime, it is only the discrete nature of matter-energy that prevents it from being explored, but there is an infinte continuous space below the subplankian regime.

Gravity effects the motion of particles, but not time itself, which is absolute and flows everywhere.

QM is more fundamental than GR, QM's ontology is more fundamental than GR"s ontology, and GR's properties are an emergent property, an illusion of a field that interacts with all other fields and fermions, not spacetime itself.

The LQG project is doomed to failure.
