According to Feynman, the cosmological constant problem tell us that there could be something profound about gravity, which we still don't know, http://members.aon.at/chakalov/Schwarz.html#1 http://members.aon.at/chakalov/Sarkar.html Going back to an old debate of 1917, it seems to me that both Levi-Civita and Einstein were undoubtedly right [Ref. 1]. More at http://members.aon.at/chakalov/Montesinos.html#1 http://members.aon.at/chakalov/Loinger.html How could Levi-Civita and Einstein be right? I'm wondering if you or any of your colleagues would agree that there is an incredible puzzle about the nature of gravity.

The stages of the theoretical discovery (1917-2003), http://arxiv.org/abs/physics/0312149 "This result has an unquestionable logical soundness, as it was finally admitted by Einstein himself. Of course, it implies the rejection of the various pseudo (false) energy tensors of the gravitational field proposed by Einstein and by other authors: a false tensor cannot have a true physical meaning! "Einstein objected that in such a way the total energy-momentum of a closed system would always be equal to zero -- and this fact would not imply the further existence of the system under whatever form. However, from the standpoint of the coherence of the formalism, Levi-Civita -- and Lorentz  -- were undoubtedly right." -------------------------------------------------------------------- non existance of gravitational waves??
