Gravity is not a hard thing to understand. If energy is released when two objects are gravitating towards each other, then something must release it. It narrows number of possible options. My current best guess is that we are inside gigantic object (about hundred of order of magnitudes larger than our Visible Universe, made of particles about few dozens order of magnitude smaller than Planck scale) with conditions similar to conditions in neutron star. So gravitation is just Casimir effect at scale.
