. With his students and collaborators, he was the first to propose that imaging this object with millimeter-interferometry would reveal the shape and size of the shadow predicted by general relativity, thereby providing empirical evidence for the validity of the
Kerr metric

, which today is poised to make a mm-wavelength image of this object as predicted almost two decades ago.
Melia and his students have developed the so-called R
h=ct Universe, a cosmological theory that, they argue, has accounted for the observational data better than all other models proposed thus far. In this cosmology, the Universe has no horizon problem, and therefore evolved without inflation.
Melia's cosmology is notable for its simplicity and its adherence to the symmetries implied by the Friedmann-Robertson-Walker metric, which require the comoving frame to be inertial. Its timeline has been confirmed by the discovery of high-redshift quasars, whose billion-solar-mass size is too large to accommodate within the compressed time scale of the standard model. In R
h=ct, these supermassive black holes would instead have easily grown by billions of solar masses via conventional Eddington-limited accretion.
