We critically review the common belief that ultrahigh energy cosmic rays are protons or atomic nuclei with masses not exceeding that of iron. We find that heavier nuclei are indeed possible, and discuss possible sources and acceleration mechanisms for such primaries. We also show detailed simulations of extensive air showers produced by “superheavy” nuclei, and discuss prospects for their detec...

An inhomogeneous cosmology describing a spacetime without symmetry is shown to be able to inflate the early universe and explain the late-time acceleration of the universe without a cosmological constant and negative pressure dark energy and avoid the coincidence problem. e-mail: [email protected]
