Query: If the spin of gravitational field depends on spacetime dimension   In this manuscript a different perspective on gravitational field has been
proposed, suggesting different features of gravity depending on spacetime
dimension, which can explain preventing the formation of singularity inside
blackholes and also suggest interpreting spin-1 fields emerged in theories with
dimensional reduction mechanism, as different aspects of gravitational field.
